FOOTNOTES:
1.	If the entrance to a garage or covered vehicular passageway faces toward the street to which its driveway has access, said entrance shall be at least 20 feet from the street lot line.
2.	At the end of each row or block of one-family attached dwellings, a yard shall be provided along the street line or side lot line of at least ten feet plus one foot for each dwelling unit in excess of two. In M and F districts, a building subject to the side yard formula: 10+L/10 may be built to the side lot line: (a) as a matter of right if, on the adjoining lot, a principal building with no setback from that lot line already exists or is proposed to be built concurrently; (b) by special permit if the Board of Appeals finds that reasonable development of the lot necessitates building to the side lot line, such action does not unreasonably infringe upon the light and air of any existing adjoining building, and the party wall is solid and has neither doors nor windows. A building with no side yard shall not have a building wall on the side lot line extending more than 70 feet to the rear of the front yard required by this By-law; except that a building wall may be located along any part of a side lot line on which a principal building on the adjoining lot abuts between the rear yard required by this By-law and the required front yard line. Where building walls more than 70 feet to the rear of the required front yard are not permitted to be built along the side lot line, said walls shall have a side yard setback not less than: 10+L/10 the "L" dimension being that portion of the wall required to be set back from the side lot line.
3.	L is the length of a wall parallel (or within 45 degrees of parallel) to the lot line, measured parallel to the lot line, subject to the provisions of § 5.41 for buildings of uneven alignment or height. H is the height, measured as provided in § 5.30, of that part of the building for which the setback or yard is to be calculated.
4.	Automotive uses are subject to the requirements of §§ 6.08 and 6.09.
5.	See § 5.07, Dwelling in Business and Industrial Districts.
6.	See § 5.54, Exception for Existing Alignment.
7.	See § 5.64, Side Yards for Non-Dwelling Uses in Business or Industrial Districts.
8.	See § 5.73, Rear Yard in Business or Industrial Districts.
9.	Where two different maximum height figures are specified with a hyphen for the same use in one zoning district, the lower figures shall apply to any lot or part of a lot located in a buffer area as defined by § 5.31, paragraph 3. Where a height figure is followed by a zoning district designation as defined in § 3.02, that figure shall be the maximum allowable height in that category for that particular district.
10.	The setback requirements for other dwelling structures in any of the S and T districts shall be the most restrictive setbacks required for the dwellings permitted in the districts, but the side yard setback shall be no less than 10 feet in any case.
11.	PBI (Public Benefit Incentives) for floor area ratio and height may be granted only if the requirements of § 5.21 and § 5.32 respectively are satisfied. B represents buffer area and NB nonbuffer area regulations. Further, projects shall also be subject to any design guidelines adopted by the Planning Board.
12.	Where any land in a G-2.0 Districts abuts a public street opposite any land in an S district, any building in the G-2.0 District shall be set back a minimum 20 feet from the street lot line facing the S district and the setback area shall be landscaped and not be used to provide parking.
13.	See § 5.91, Minimum Usable Open Space, for open space requirements for residential use with more dwelling units than are permitted as of right in that district.
14.	For life care facilities in S-25 districts, the Board of Appeals may allow by special permit an FAR up to 0.3, where appropriate public benefits are provided, such as listed in § 5.21, paragraph 1.
15.	For dwelling subject to § 5.11, paragraphs 2 and 3, the allowed floor area ratio maximum shall be the same as for 1-family detached dwellings subject to § 5.11, paragraph 1 in the relevant zoning district.
16.	In the G-1.75 (LSH) Limited Service Hotel District, for Use 8A, Limited Service Hotel, the following dimensional requirements are allowed: Floor Area Ratio Maximum of 3.30; Height Maximum of 90 Feet and 8 stories above grade; and Minimum Rear Yard - None.
17.	See Section 5.06 - Special District Regulations, d. General Business and Medical Research (GMR).
18.	See Section 5.06(4)(g), Special District Regulations with respect to uses and all dimensional requirements.

19.	See Section 5.06 - Special District Regulations, subsections f. Cleveland Circle Local Business District L-0.5 (CL) and i. Cleveland Circle Hotel Overlay District.
20.	See Sections 4.07 and 5.06.4.j with respect to uses and all dimensional requirements.
21.	See Section 5.06.4 – Special Districts, subsections b. Coolidge Corner General Business District G-1.75(CC) and k. Waldo-Durgin Overlay District with respect to uses and all dimensional requirements.

§ 5.00 DISTRICT REGULATIONS

1. Except for districts in the Harvard Street Main Street Corridor, the regulations for each district pertaining to minimum lot size, minimum lot area per dwelling unit, minimum lot width, maximum height of buildings, maximum floor area ratio, minimum usable open space per dwelling unit, minimum front yard depth, minimum side yard width, minimum rear yard depth, minimum setback distance of top of wall from any lot line, shall be as specified in this section, Table 5.01, Table of Dimensional Requirements, subject to the further provisions of Article V. For districts in the Harvard Street Main Street Corridor (H-MS, H-MS-O, H-MST, H-MSN), Article XI supersedes § 5.01 through § 5.05, § 5.06.4.a through § 5.06.4.o, and § 5.07 through § 5.92 in its entirety.

GENERAL REGULATIONS

§ 5.01 LOT AREA OR YARDS REQUIRED

The lot or yard areas required for any new building or use shall not include any part of a lot that is required by any other building or use to comply with any requirements of this By-law. No required lot or yard area shall include any property the ownership of which has been transferred subsequent to the effective date of this By-law if such property was a part of the area required for compliance with the dimensional requirements applicable to the lot from which such transfer was made.

§ 5.02 SPACING OF NON-RESIDENTIAL BUILDINGS ON THE SAME LOT

Where two or more main buildings for other than residential uses are proposed to be built upon property in one ownership, front, side, and rear yards are required only at lot lines abutting other property.

Figure 5.01 - Buildings on the Same Lot

§ 5.03 SPACING OF RESIDENTIAL BUILDINGS ON THE SAME LOT

Where two or more main buildings to be used as family dwellings are proposed to be built upon property in one ownership or where one or more such buildings are proposed upon property where there are one or more existing residential buildings, except as provided in § 5.04, required front, side, and rear yards shall be provided between each building and assumed lot lines shown upon the building permit application. The Board of Appeals, however, may by special permit, modify the yard dimensions between such buildings designed and intended to remain under the same ownership and management where it is demonstrated that there will result light, air, sunlight, and amenity of a standard no lower than would result from such requirements.

§ 5.04 RESIDENTIAL BUILDING ON REAR OF A LOT

Where a permitted main building, designed for occupancy by one or more families, is to be located on the same lot with and to the rear of another permitted main building, each such building shall be independently provided with all required front, side, and rear yards, and required lot area; and the distance between such buildings shall not be less than twice the required rear yard depth. The Board of Appeals, however, may by special permit modify the yard dimensions between such buildings intended to remain under the same ownership and management where it is demonstrated that there will result light, air, sunlight, and other amenities of a standard no lower than would result from such requirements. Access to the street shall be provided as specified in § 5.14.

Where an existing garage, stable or similar detached structure on the rear of a lot with a permitted main building, is to be converted for the occupancy of one or more families, the provisions of paragraph 1. above shall apply.

Figure 5.02 - Residential Building on Rear of a Lot

§ 5.05 CONVERSIONS

In the case of the conversion of a single-family detached dwelling to a two-family dwelling in an SC or T District, or the conversion of a dwelling to create additional dwelling units in an F or M District, the structure shall conform to all dimensional requirements specified in § 5.01. However, the Board of Appeals by special permit may waive any of said dimensional requirements, provided that no previously existing nonconformity to such requirements is increased and provided that all other requirements of this By-law for such conversions are met.

§ 5.06 SPECIAL DISTRICT REGULATIONS

Purpose

The following Special District Regulations recognize that unique land use, environmental, architectural and other physical conditions present within the Town may require detailed neighborhood, district or site planning and design review to insure: orderly and planned growth and development; historic and natural resource conservation; residential neighborhood preservation; economic viability of commercial areas; and concurrent planning for transportation, infrastructure and related public improvements. To insure that the dimensional and related requirements of the Zoning By-Law address these unique conditions, Town Meeting, from time to time, in accordance with M.G.L. Chapter 40A, may establish Special District Regulations and the Board of Appeals may consider applications for Special Permits based on those regulations.

Establishment

The establishment of Special District Regulations shall be based on one or more of the following:

A study of land use, building, environmental, economic, architectural, design or other physical features of an area or district that defines the conditions and purposes supporting the establishment of Special District Regulations and the geographic area that will be subject to the regulations.

The Comprehensive Plan, neighborhood or commercial area plan that defines an area where Special District Regulations should be applied.

A conceptual or schematic design plan for one or more parcels of land or buildings within a district that will benefit from Special District Regulations.

Procedures

Applicants for Special Permits, subject to Special District Regulations, shall submit to the Board of Appeals the supporting studies and plans defined by § 5.06.2.

Special Districts

Multiple or Attached Dwelling Development in S-0.75P District

For a multiple or attached dwelling development in an S-0.75P District, in addition to the special permit findings in § 9.05, paragraph 1., the Board of Appeals must find that the development will preserve a substantial portion of the existing buildings on the site and significant architectural features thereof, particularly those buildings with historical significance.

Such developments shall be subject to the Community and Environmental Impact and Design Review procedures and standards of § 5.09, Design Review.

For such developments, the Board of Appeals may grant by special permit a maximum gross floor area and a number of dwelling units higher than permitted in Table 5.01 where any of the following conditions obtain, provided that the increase shall not exceed 10% for each condition below and shall not exceed 20% in total beyond what is permitted in Table 5.01, but such floor space shall not be included in the gross floor area for the purpose of calculating parking requirements.

Setbacks of proposed buildings from abutting residential property: 1% bonus per 10% setback increase in excess of required. The setback shall be calculated as the weighted average setback based on the length of the proposed building(s) from the nearest lot line abutting or across the street from residential property.

Open space in excess of total required open space: 1% bonus per 10% extra open space (either landscaped, usable, or a combination thereof).

Concealed parking: 1% bonus per 5% of required parking concealed below grade or within a residential structure.

Coolidge Corner General Business District G-1.75 (CC)

All applications in the G-1.75(CC) District shall be subject to § 5.09, Design Review. The Preservation Commission, Transportation Board, or any other interested Town body may submit an advisory report to the Planning Board and Board of Appeals for their consideration. Any such reports shall be transmitted to the Board of Appeals with the Planning Board report and shall be considered therewith.

For such applications, the Board of Appeals may grant by special permit an increase in gross floor area subject to the procedures, limitations, and conditions of Table 5.01 and § 5.21.

For such applications, the gross floor area of the building used to calculate the maximum permitted floor area ratio shall include the floor space at or above grade in an accessory building or in the main building intended and designed for the parking of motor vehicles, but such floor space shall not be included in the gross floor area for the purpose of calculating parking requirements.

For such applications, the Board of Appeals may grant by special permit an increase in height in accordance with the procedures, limitations, and conditions of Table 5.01 and § 5.32.

For such applications, residential development shall be permitted above the first floor.

For such applications within the Waldo-Durgin Overlay District, the Board of Appeals may grant by special permit an increase in gross floor area or height subject to the procedures, limitations, and conditions of § 5.06.4.k.

Multiple or Attached Dwelling Development in S-0.5P District

For multiple or attached dwelling developments in an S-0.5P District, in addition to the Special Permit findings in § 9.05, paragraph 1., the Board of Appeals must find that:

the development will preserve a parcel of land of seven (7) acres or more as a single lot, with not less than 6 acres as open space, which may be in condominium ownership, and will preserve significant exterior architectural features of significant historical buildings on the site, but excluding minor buildings such as sheds, garages, greenhouses etc., located on said parcel and significant landscape and topographic features, and

at least seventy-five percent (75%) of all parking spaces required by the Zoning By-law will be located in a subsurface parking garage.

Such development shall be subject to the procedures and standards of § 5.09, Design Review.

For such development, the Board of Appeals may grant by Special Permit a maximum height greater than is permitted in Table 5.01 for building(s) on a single lot, provided that the maximum height shall not exceed 70 feet. The Board of Appeals, however, may require a greater front yard setback for any part of the building taller than 40 feet if necessary to reduce the impact on abutting single family residences to a reasonable degree. Notwithstanding any other provision of this By-law, for the purpose of this § 5.06, paragraph 3. only, height is defined as the vertical distance to the top of the highest roof ridge from the average of finished ground level adjoining the building at all exterior walls.

General Business and Medical Research (GMR)

All major impact applications for new structures, outdoor uses, and exterior alterations or additions in the GMR-2.0 District shall be subject to the requirements of § 5.09, Design Review, obtain a special permit per § 9.03, and meet the following requirements:

the maximum height shall not exceed 115 feet. The maximum gross floor area and open space requirements as described in Table 5.01 shall be determined based on the combined total area of all lots within the GMR-2.0 District.

no less than 35% of the total area of all lots within the GMR-2.0 District shall be devoted to open space, consisting of the part or parts of the lots at ground level designed and developed for pleasant appearance with trees and shrubs, ground covers and grass, including other landscaped elements such as natural features of the site and walks and including areas developed for outdoor use for recreation. Such space may not include lot area used for automotive circulation or parking. Hard surfaced walks and plazas may not exceed 55% of the total area required for such open space.

The buildings shall be subject to the following special dimensional requirements, as illustrated in the Figure at the end of § 5.06(4)d:

No buildings shall be constructed within the area defined by the north and west Pearl Street property lines, and lines perpendicular to said boundary lines, one line 80 feet from the intersection of the west and north boundary lines on the west boundary line, and the other line 115 feet from the intersection of the west and north boundary lines on the north boundary line. In a situation where the interpretation of the boundaries of such area is not clear, the Board of Appeals may determine a no-build area that it deems will best approximate the requirements of this subsection;

ii)

Any development that has frontage on both Pearl Street and Washington Street shall contain an area designed and intended for non-vehicular use not less than 45 feet in width that is interior to such development area and not on the perimeter bounding Pearl Street or Washington Street, which area shall be kept open for public pedestrian passage;

iii)

The maximum height of any building measured to the top of the railings or parapet above the roof shall not exceed 65'-0" within the area defined by the Pearl Street north and east property lines, a line parallel to the north boundary line located 130'-0" from said boundary line, and a line perpendicular to the north boundary line located 115 feet from the intersection of the north and west boundary lines. It shall not exceed 55 feet within the portion of this area defined by the Pearl Street north and east property lines, and a line 30' from the east boundary line and parallel to said boundary line. In a situation where the interpretation of the boundaries of such area is not clear, the Board of Appeals may determine an area that it deems will best approximate the requirements of this subsection. Only in the area in which the height of 65'-0" is permitted, substantial rooftop structures such as observation towers, elevator penthouses and mechanical equipment may exceed this height limit by 10 feet or such greater amount as may be authorized by special permit granted by the Board of Appeals;

iv)

The gross floor area of the buildings used to calculate the maximum permitted floor area ratio shall include the floor space at or above grade in an accessory building or in a main building intended and designed for the parking of motor vehicles, but such floor space shall not be included in the gross floor area for the purpose of calculating parking requirements;

There shall be a front yard setback of 9 feet from the front lot line bordering Washington Street and Brookline Avenue, subject to modification by the Board of Appeals as provided in Section 5.43.

no less than 25% of the provided parking spaces shall be offered to residents for overnight parking.

no less than 1% of the hard construction costs of constructing a building within the GMR-2.0 District (exclusive of tenant fit-up) shall be devoted to making off-site streetscape improvements (such as, but not limited to, lighting, street furniture and widening sidewalks) and undertaking transportation and community benefit mitigation measures. In addition to review by the Planning Board, a plan of the proposed off-site streetscape improvements and a description of the proposed transportation mitigation measures shall be submitted for the review and approval of the Director of Transportation and the Director of Parks and Open Space or their designees.

The parking requirements for applications in the GMR-2.0 District shall be reviewed as a single lot without regard to lot ownership and in light of the proximity to rapid public transit shall be as follows:

retail use: one parking space per 533 g.s.f. of floor area

office use: one parking space per 800 g.s.f. of floor area

research laboratory use (Use 36B): one parking space per 1,250 g.s.f. of floor area

medical office use: one parking space per 467 g.s.f. of floor area

For any major impact project within the GMR-2.0 District, a Transportation Access Plan Agreement ("TAPA") that includes recognized Transportation Demand Management ("TDM") programs shall be a condition of the special permit. Such TAPA shall be submitted to the Director of Transportation and the Director of Planning and Community Development for their review and approval. All owner(s) of the property or properties subject to the special permit shall submit an annual report for review and approval to the Director of Transportation relative to the implementation and effectiveness of the TAPA. The Director of Transportation in consultation with the Director of Planning and Community Development shall determine whether the TAPA is working satisfactorily or whether reasonable modifications to the TAPA are required. The TAPA shall be modified to incorporate any reasonable requests of the Director of Transportation within sixty (60) days after they issue their determination. Failure to issue such a determination within sixty (60) days of receiving the annual report shall be deemed acceptance of the report and existing provisions of the TAPA. If any owner objects to any new request as being unreasonable or not required, such matter may be presented to the Transportation Board for recommendation to the Board of Appeals for determination.

The maximum number of parking stalls within the GMR-2.0 District shall not exceed 683, excluding drop-off and loading zones. The Board of Appeals may also approve, based on the criteria set forth in § 9.05, accommodation of up to 20% additional number of vehicles, which may be in tandem parking arrangement, and/or any other parking arrangement, operation or devices that enable additional vehicles to be accommodated within parking garages.

All structures and uses in the GMR-2.0 District shall be subject to the following provisions, including both developments that constitute major impact projects and developments that do not constitute major impact projects:

Notwithstanding any other provision of this by-law with respect to calculating allowable height of a building, within the GMR-2.0 District the height for a building shall be measured from the mean natural grade of ground contiguous to such building. In a situation where the interpretation of natural grade is not clear, the Board of Appeals may determine height that it deems will best approximate the requirements of this subsection.

All lot lines which are not front lot lines shall be subject to the provisions applicable to side lot lines.

Buildings within 125 feet of the intersection of Pearl Street and Brookline Avenue property lines shall be no taller than 30 feet, as illustrated in the Figure at the end of § 5.06(4)d. In a situation where the interpretation of the point from which the height restriction is measured is not clear, the Board of Appeals may determine the restricted area that it deems will best approximate the requirements of this subsection.

Prior to the issuance of any special permit for a major impact project under § 5.06(4) d(1), the maximum gross floor area and open space requirements as described in Table 5.01 shall be determined based on the Lot Area and not based on the combined total area of all lots within the GMR-2.0 District. Subsequent to the issuance of any special permit for a major impact project under § 5.06(4)d(1) that has not lapsed, the maximum gross floor area and open space requirements as described in Table 5.01 shall be determined based on the combined total area of all lots within the GMR-2.0 District.

A special permit granted under this section as well as special permits granted under other sections of the Zoning By-law that are combined in a single decision with the special permit granted under this section shall lapse within 2 years if a building permit is not issued and construction has not begun by such date except for good cause.

By special permit of the Board of Appeals, signs may be permitted on building walls not parallel or within 45 degrees of parallel to the street.

Figure 5.02a - Special Dimensional Requirements for the GMR District

Fisher Hill Town-Owned Reservoir Site Mixed Income Housing Overlay

It is found that the Fisher Hill Town-Owned Reservoir Site (the "Site") has been identified in the Town's Comprehensive Plan and through a Fisher Hill Planning Process ("Planning Process") as an appropriate site for mixed-income housing development of a high quality and contextual design. For this reason, the development of the Site shall be permitted under the criteria of this section. It is further found that, due to the sensitive nature of the Site, a construction oversight committee of neighbors and other stakeholders will be charged to advise the Building Commissioner during construction.

Any applicant may seek relief under this overlay, provided it meets the following requirements:

It contains no more than 40 units of housing.

More than 50% of the units on the Site shall be affordable, defined generally in accordance with Section 4.08.2.c, to households with incomes up to 120% of median income, defined in accordance with Section 4.08.2.f. These units shall include at least 25% of the units on the Site that shall be affordable to households with incomes up to 80% of median income and which shall also qualify for the Town's Subsidized Housing inventory as per Massachusetts General Laws Chapter 40B and 760 CMR 56., including requirements for minimum unit size. In no case, however, shall an affordable unit be smaller than those sizes listed in Section 4.08.6.c of the Zoning Bylaw. These affordable units shall, to the extent feasible, consist of an equal mix of 2 and 3 bedroom units.

Any development plan that is created under this overlay district shall include the full design and/or design guidelines for each component of the development as well as landscape guidelines for the overall district. The Planning Board shall review and approve the guidelines with any modifications the Board sees fit. The approved design and/or guidelines shall be binding on any future purchaser or developer of any component of the development.

A project that qualifies for use of this overlay district shall be subject to the following review criteria and process:

The applicant shall apply for a Special Permit, which the Board of Appeals may grant if, upon review of a master site plan, it finds that the project meets the following criteria:

It has met all the requirements of Section 9.05 of the Zoning Bylaw;

It has met the requirements of Section 5.09 of the Zoning Bylaw relating to Design Review for a Major Impact Project;

It is consistent with the design guidelines approved by the Planning Board as per 5.06.4.e.3 above;

It has a viable plan for maintaining affordability for the longest period permitted by law that has been approved by the Department of Planning and Community Development.

A preliminary subdivision plan for the Site must be approved by the Planning Board. In addition, if any Approval Not Required lots are to be created along Fisher Avenue as part of this project, the Planning Board must complete its review of the ANR plan. A definitive subdivision plan that addresses any conditions placed on the preliminary plan and ANR lots may be submitted subsequent to receipt of this Special Permit. A Special Permit granted under this overlay shall be conditioned upon approval of the definitive subdivision.

If this initial Special Permit is granted, and the land is subdivided as per the approved definitive subdivision plan, construction on each lot shall be permitted subject to the conditions set forth in the Special Permit, which shall include design review by the Planning Board. Such design review shall be conducted as per sign/facade review in Section 7 of the Zoning Bylaw, and shall determine consistence with the project Special Permit, including design guidelines. The specific location of each single-family detached and attached dwelling unit within a parcel may be adjusted as part of this review, provided that it meets all setback requirements and is otherwise consistent with the dimensional requirements of the Special Permit and design guidelines.

Any lot that is created as part of this process and is not built upon within 3 years of issuance of the Special Permit must be landscaped consistent with the overall landscape plan approved for the Site as part of the Special Permit.

Any Special Permit sought under this overlay district shall permit the following uses for lots located in their entirety more than 100 feet from Fisher Avenue:

Principal Use 5 (attached dwelling unit). For this use, no side yard setback is required on the attached side of the structure.

Principal Use 4A (dwelling in a separate lot for three families or attached dwelling on a separate lot for two families); however, only three-family dwellings shall be permitted; and

Principal Use 6 (multiple or attached dwelling of four or more units), provided that no more than 4 units may be contained on any one lot other than as provided for in 5.06.e.6.a.4 below.

Any other uses sought shall be in accordance with other relevant sections of this Zoning Bylaw.

Any Special Permit sought under this overlay district shall permit development subject to the following dimensional requirements, superseding any conflicting requirements in Sections 5 and 6 of the Zoning Bylaw for the underlying zoning district.

Provided that the Site is laid out consistent with the design guidelines outlined above and in the Planning Process, the Site may be developed subject to the following restrictions:

An overall maximum Floor Area Ratio of 0.4, or a maximum total of 72,000 square feet shall be permitted.

No building located on any part of the Site other than the "Multifamily Lot" referred to in 5.06.e.6.4.a. below, shall be larger than 4,500 square feet of Gross Floor Area.

No attached single-family dwelling unit shall be larger than 3,500 square feet.

One lot ("the Multifamily Lot") shall be permitted to have a set of buildings under uses 4A, 5, and 6, provided the Gross Floor Area of these buildings does not exceed 36,000 square feet.

Minimum lot sizes and widths, yard setbacks, and open space requirements in the overlay may be reduced as part of the overall Special Permit provide the plan is consistent with the vision for the Site referred to in the Planning Process. However, no more than four lots on the site shall be smaller than the 15,000 square feet.

Consistent with the Town's Planning Process, more than one principal structure shall be permitted on the same lot, for the Multifamily Lot only. For that parcel only, the maximum height permitted may also be increased to 45 feet. For all other buildings, the base zoning district maximum height requirement of 35 feet shall apply.

Consistent with the Town's Planning Process, parking requirements under Article 6 of the Zoning Bylaw may be modified. In particular, the parking requirement for the affordable units shall be 1.75 spaces per unit. A significant majority of the parking shall be located below grade, in garages, or otherwise shielded from public view.

Consistent with the higher level of affordability on this site required by the Town's Planning Process, Section 4.08 of the Zoning Bylaw shall not apply to projects using this overlay, with the exception of the minimum unit sizes in Section 4.08.6.c.

These dimensional restrictions apply to the overlay district as a whole and shall not be exceeded on the Site if it is developed by more than one applicant.

Any other dimensional relief sought shall be pursued as per any other relevant sections of this Zoning Bylaw.

Once any lot in the Site is subdivided and conveyed to be used for construction of a single-family home or an attached dwelling unit (a "Sold Lot"), the Sold Lot shall not be in violation of this Section 5.06.4.e or any other provision of the Zoning Bylaw or any Special Permit granted with respect to the Site by virtue of any violation of any other lot in the Site. Likewise, no other lot in the Site shall be in violation of this Section 5.06.4.e or any other provision of the Zoning Bylaw or any Special Permit granted with respect to the Site by virtue of any violation of any Sold Lot.

Cleveland Circle Local Business District L-0.5(CL)

It has been determined through study of the Local Business District in Cleveland Circle that there exists potential for redevelopment of much of this district. It has further been determined that, due to the circulation and multiple transit systems in this area as well as the proximity of the municipal boundary with Boston, any redevelopment in this district would need to be closely analyzed for its impacts on the roadway, transit and pedestrian system and for its overall design taking into consideration previous mitigation due to traffic flow patterns within the district.

All applications in the L-0.5(CL) district shall be subject to § 5.09, Design Review. Further, any development in this district shall, for the purposes of determining if it is a Major Impact Project under § 5.09.3.b., be viewed in its entirety, even if a portion of the project is located in another municipality.

All Major Impact Projects in this special district shall be required to submit a traffic impact and access study that clearly outlines the strategy for providing access to and from the proposed development and the impacts of that access on the transportation system of the Town, the area's mass transit systems, pedestrian and bicycle circulation, and public safety in this area. The Board of Appeals may condition any Special Permit under § 5.09 on a specific plan for traffic mitigation that will take into consideration previous mitigation due to traffic patterns within the district and, if appropriate, compliance with an approved Transportation Demand Management program.

In any review of a project that is located across municipal boundaries, the project and improvements shall be reviewed as a single lot, without regard to municipal boundaries, in connection with parking requirements or setbacks. Additionally, any Design Review per Section 5.09 shall include review and approval of the entire length of the facade facing the MBTA property line as well as any lighting proposed along this length, irrespective of municipal boundaries. Such facade shall be designed and constructed with care and quality of finishes equivalent to the northern facade.

Davis Path Special District G-(DP)

It has been found through study by the Davis Path Special District Zoning Study Committee that very specific rules are required to encourage appropriate redevelopment of the Davis Path Special District, due to the combination of the close proximity of the White Place National Register District, which contains residential uses on lots that are relatively shallow in depth, the substantial differences in elevation between the Davis Path Special District and the White Place district, the substantial differences in the scale of existing buildings in the White Place district and existing and proposed development in the Davis Path Special District, and the solar orientation of White Place district and the Davis Path Special District. Following a comprehensive study by financial, architecture, and transportation experts, the Committee further concluded that the concepts relating to Building Envelope, facade articulation, and parking requirements have only been deemed appropriate for this Special District, and not intended to affect other districts.

For the purposes of the Special District, any proposed building shall be permitted to have more than one principal use. For example, a restaurant greater than 5,000 square feet may be located in the same building as a Limited Service Hotel without being considered an accessory use.

Building Envelope

This section describes the three dimensional space within which all Building Construction must occur, subject to further limitations and exceptions as provided in this Section 5.06.4.g. Notwithstanding the provisions of Section 5.31, Building Construction shall include all portions of a structured parking area or building, including elevator penthouses, mechanical equipment enclosures, water tanks and water towers, and cooling towers, with only the exceptions set forth in Section 5.06.4.g.3.e below.

Minimum Yard Setbacks shall be defined as follows:

20 feet from the property line bordering the MBTA property.

ii.

7 feet from the property line bordering Davis Path.

iii.

5 feet from the property line bordering Boylston Street for the ground floor (excluding support columns).

iv.

5 feet from the eastern property line of the G-(DP) District.

Height of Building shall be measured from the District Record Grade rather than as prescribed in Section 5.30. The District Record Grade shall be the record grade of Boylston Street at the edge of pavement opposite the midpoint of the southern boundary of the G-(DP) district. The Height of Building shall be in no case taller than 65'. Additionally, any elevator penthouse, mechanical equipment enclosure, water tanks and water towers, or cooling towers may in no case be taller than 80' from the District Record Grade. Notwithstanding the foregoing, in no case may any Building Construction exceed the Building Envelope set forth in Section 5.06.4.g.3.d below, except as expressly provided in Section 5.06.4.g.3.e below.

Figure 5.02b - Height of Building Measurements in the G-(DP) District

The Building Envelope shall be further restricted by an Angled Plane beginning at an elevation 20 feet above the District Record Grade and aligned with the MBTA property line, with such plane rising toward Boylston Street at an angle of one foot of vertical height for every 2.25 horizontal feet from the MBTA property line in a direction perpendicular to the MBTA property line.

Figure 5.02c - Angled Plane Diagram

Exceptions to the Building Envelope may be permitted only as follows:

Flag poles and transmission towers not exceeding 5 feet in horizontal width including appurtenant equipment;

ii.

railings up to 44" high provided they are at least 75% open (measured at 90 degrees to the vertical surface);

iii.

seasonal shading devices, including any awnings and canopies, provided they are removed between October 1st and April 1st; and

iv.

if within 72' of the Boylston Street property line, a projection or projections containing no more than 4,000 square feet of total gross floor area, such floor area to be measured by the area of the floor immediately below any mass that penetrates the Angled Plane, but in no case 15 feet above the Building Envelope at any point as shown in Figure 5.02d.

Figure 5.02d - Diagram of Allowable Projection Above Angled Plane

No relief by Special Permit may be approved for setbacks, height, floor area ratio, or projections above the defined Building Envelope beyond any provisions specified in this Section 5.06.4.g. For example, relief from setbacks per Section 5.43 shall not be available for buildings within these provisions. Similarly, the "public benefit incentive" exceptions to floor area ratio and height regulations set forth in Sections 5.21 and 5.32 shall not apply.

Any building facade parallel to or within 45 degrees of parallel to any property line other than the eastern property line shall be designed and constructed with care and quality of design equivalent to the Boylston Street facade. Visual articulation shall be achieved for each such facade by (a) employing variations in materials and/or ensuring that no portion of any such facade is coplanar for more than 3,500 square feet without a change in depth of 2 feet or more in depth, or (b) utilizing other design elements that, in the affirmative and written determination of the Design Advisory Team provide equivalent or better visual relief with respect to building massing, for reasons expressed in such written determination. The Planning Board and the Board of Appeals shall provide a similar written determination and reasons with respect to facade design.

Nearby properties, including properties north of the MBTA property, shall be visually screened and protected from the lights of any parking lot or garage by compliance with the requirements of Section 6.04.6, notwithstanding the fact that such properties do not abut and are not across the street from any proposed parking lot or garage.

All applications for new structures, outdoor uses, and exterior alterations or additions in the G-(DP) District which seek a floor area ratio (FAR) greater than 1.0 or reduced parking requirements shall be permitted only on a lot no less than 28,000 square feet in contiguous area, shall be subject to the requirements of Section 5.09, Design Review, obtain a special permit pursuant to Section 9.03, and meet the following requirements:

All underlying provisions described in Section 5.04.6.g.1 to 5.04.6.g.6 above.

An FAR above 1.0 may be increased by special permit up to 3.0 for Principal Use 8A (Limited Service Hotel), up to 2.0 for other residential uses, and up to 2.25 for all other uses. Where a building contains more than one use, the gross floor area attributable to each use (including an allocated portion of any common areas) shall be computed and divided by the total allowable gross floor area for such use to determine a percentage. The total of all percentages for all uses shall not exceed 100%.

Parking and Vehicular Requirements

Parking requirements may be reduced from Section 6.02, Paragraph 1, the Table of Off-Street Parking Space Requirements, for the following uses:

Residential studio units that are less than 500 net square feet in size: 1.0 parking spaces per dwelling unit

Residential units that are less than 700 net square feet in size and have less than 2 bedrooms: 1.25 parking spaces per dwelling unit

Limited Service Hotel: 0.5 spaces per room and no additional spaces shall be required for floor areas used for eating, drinking, dancing, meeting halls or similar purposes

Retail: one space per 500 g.s.f.

Office: one space per 600 g.s.f.

Medical and Dental Office: one space per 400 g.s.f.

ii.

In addition to relief available under Section 6.04.14.c, the width of a building facade facing or within 45 degrees of parallel to the Boylston Street property line devoted to the entrance or exit of a garage, carport, loading dock, parking area or other vehicular use may as of right:

exceed twenty-four feet in width, provided, however, that no such individual entrance or exit shall exceed 30 feet in width and the total width of all entrances and exits shall not be more than 40% of the facade; and

in the case of multiple entrances, the measurement shall not include the portion of any facade between the entrances that is usable floor area.

iii.

Notwithstanding the provisions of Section 6.06.6, only one loading dock shall be required.

iv.

Notwithstanding the provisions of footnote 1 of the Table 5.01 Dimensional Requirements, the entrance to a garage or covered vehicular passage facing the street shall be at least 5 feet from the street lot line.

The applicant shall provide trees at regular intervals approximately every 25' along the public sidewalk of Boylston Street. The final design of landscaping along the public sidewalk shall be approved by the Director of Parks & Open Space or their designee.

In addition to (d) above, the applicant shall devote no less than 1% of the hard construction costs (including any site work, above-ground or underground structures, but exclusive of tenant fit-up) towards improvements to the adjacent Davis Path and/or Boylston Street Playground, with such improvements subject to the review and approval of the Director of Parks & Open Space or their designee, or, in the alternative, the applicant shall make a cash payment to the Town in an equivalent amount to be utilized by the Town for such purposes.

Renewable Energy Overlay District (SOL)

The Town is interested in being designated a Green Community by the Commonwealth of Massachusetts. The Town is also committed to decreasing its carbon footprint by encouraging the development of alternative energy supplies. For these reasons, the Town has surveyed potential sites for a renewable energy facility and created this overlay district.

Notwithstanding any other portion of the Zoning Bylaw, including Section 4.07 - Table of Uses, the location of renewable energy generation facilities in the form of ground-mounted solar photovoltaic arrays shall be permitted by-right in this district. While both large- and small-scale solar photovoltaic facilities are allowed, large-scale solar photovoltaic facilities are encouraged.

Compliance with Laws, By-laws and Regulations: The construction and operation of all solar photovoltaic installations, large or small, shall be consistent with all applicable local, state and federal requirements, including but not limited to all applicable safety, construction, electrical, and communications requirements. All buildings and fixtures forming part of a solar photovoltaic installation shall be constructed in accordance with the State Building Code.

No ground-based solar photovoltaic installation shall be constructed, installed or modified as provided in this section without first obtaining a building permit.

Site Plan Review: Such facilities shall be subject to site plan review by the Planning Board to ensure that the facility is adequately set back from neighboring properties, reasonably shielded from view, and that utility connections are adequately screened. Such site plan review shall be conducted in accordance with the design review process outlined in Section 7.03, paragraph 2, of the Zoning Bylaw with the exception that such site plan review is not discretionary and any conditions attached cannot render a Large Scale Solar Facility (of at least 250 kW DC) infeasible. All plans and maps submitted for site plan review shall be prepared, stamped, and signed by a Professional Engineer licensed to practice in Massachusetts. Pursuant to the site plan review process, the project proponent shall provide to the Planning Board the following documents:

A site plan showing:

Property lines and physical features, including roads, for the project site;

ii.

Proposed changes to the landscape of the site, grading, vegetation clearing and planting, exterior lighting, screening vegetation or structures;

iii.

Blueprints or drawings of the solar photovoltaic installation signed by a Professional Engineer licensed to practice in the Commonwealth of Massachusetts showing the proposed layout of the system and any potential shading from nearby structures;

iv.

Off-grid systems shall be exempt from this requirement.

Dimension and Density Requirements

Setbacks: For ground-mounted solar photovoltaic installations, all setbacks from lot lines shall be at least 25 feet. As part of Site Plan Review, the Planning Board may require larger setbacks if appropriate for screening, provided, however, that such larger setbacks shall not have the effect of rendering a Large Scale Solar Facility (of at least 250 kW DC) infeasible.

Appurtenant Structures: All appurtenant structures to ground-mounted solar photovoltaic installations shall be subject to reasonable regulations concerning the bulk and height of structures, lot area, setbacks, open space, parking and building coverage requirements. All such appurtenant structures, including but not limited to, equipment shelters, storage facilities, transformers, and substations, shall be architecturally compatible with each other. Whenever reasonable, structures should be shaded from view by vegetation and/or joined or clustered to avoid adverse visual impacts.

10)

Design Standards

Lighting: Lighting of ground-mounted solar photovoltaic installations shall be consistent with local, state and federal law. Lighting of other parts of the installation, such as appurtenant structures, shall be limited to that required for safety and operational purposes, and shall be reasonably shielded from abutting properties. Where feasible, lighting of the solar photovoltaic installation shall be directed downward and away from residential structures and shall incorporate full cut-off-fixtures to reduce light pollution.

Signage: Signs on ground-mounted solar photovoltaic installations shall comply with the regulations of Article 7. A sign consistent with these regulations shall be required to identify the owner and provide a 24-hour emergency contact phone number. Solar photovoltaic installations shall not be used for displaying any advertising except for reasonable identification of the manufacturer or operator of the solar photovoltaic installation.

Utility Connections: Reasonable efforts, as determined by the Building Commissioner, shall be made to place all utility connections from the solar photovoltaic installation underground, depending on appropriate soil conditions, shape, and topography of the site and any requirements of the utility provider. Electrical transformers for utility interconnections may be above ground if required by the utility provider, however, they shall be screened from view.

11)

Safety and Environmental Standards

Emergency Services: The large scale solar photovoltaic installation owner or operator shall provide a copy of the project summary, electrical schematic, and site plan to the local fire chief. Upon request the owner or operator shall cooperate with local emergency services in developing an emergency response plan. All means of shutting down the solar photovoltaic installation shall be clearly marked. The owner or operator shall identify a responsible person for public inquiries throughout the life of the installation.

Land Clearing, Soil Erosion, and Habitat Impacts: Clearing of natural vegetation shall be limited to what is necessary for the construction, operation and maintenance of the ground-mounted solar photovoltaic installation, or otherwise prescribed by applicable laws, regulations, and bylaws.

12)

Monitoring and Maintenance

Solar Photovoltaic Installation Conditions: The ground-mounted solar photovoltaic installation owner or operator shall maintain the facility in good condition. Maintenance shall include, but not be limited to, painting, structural repairs, and integrity of security measures. Site access shall be maintained to a level applicable to the local Fire Chief and Emergency Medical Services. The owner or operator shall be responsible for the cost of maintaining the solar photovoltaic installation and any access road(s), unless accepted as a public way.

Modifications: All material modifications to a solar photovoltaic installation made after issuance of the required building permit shall require approval by the Planning Board.

13)

Abandonment or Decommissioning

Removal Requirements: Any ground-mounted solar photovoltaic installation that has reached the end of its useful life or has been abandoned consistent with sub-paragraph 13.b of this section shall be removed. The owner or operator shall physically remove the installation no more than 150 days after the date of discontinued operations. The owner or operator shall notify the Building Commissioner by certified mail of the proposed date of discontinued operations and plans for removal. Decommissioning of the installation shall consist of:

Physical removal of all large-scale ground-mounted solar photovoltaic installations, structures, equipment security barriers and transmission lines from the site.

ii.

Disposal of all solid and hazardous waste in accordance with local, state, and federal waste disposal regulations.

iii.

Stabilization or re-vegetation of the site as necessary to minimize erosion. The Building Commissioner may allow the owner or operator to leave landscaping or designated below-grade foundations in order to minimize erosion and disruption to vegetation.

Abandonment: Absent notice of a proposed date of decommissioning or written notice of extenuating circumstances, the solar photovoltaic installation shall be considered abandoned when it fails to operate for more than one year without the written consent of the Planning Board. If the owner or operator of the ground-mounted solar photovoltaic installation fails to remove the installation in accordance with the requirements of this section within 150 days of abandonment or the proposed date of decommissioning, the town may enter the property and physically remove the installation.

Financial Surety: Proponents of ground-mounted solar photovoltaic projects shall provide a form of surety, either through escrow account, bond or otherwise, to cover the cost of removal in the event the town must remove the installation and remediate the landscape, in an amount and form determined to be reasonable by the Building Commissioner, but in no event to exceed more than 125 percent of the cost of removal and compliance with the additional requirements set forth herein, as determined by the project proponent. Such surety will not be required for municipally- or state-owned facilities. The project proponent shall submit a fully inclusive estimate of the costs associated with removal, prepared by a qualified engineer. The amount shall include a mechanism for calculating increased removal costs due to inflation.

Cleveland Circle Hotel Overlay District

It has been determined through study of the Local Business District in Cleveland Circle that potential exists for appropriate, planned redevelopment of the western side of this Local Business District. It has further been determined that, due to the circulation and multiple transit systems in this area as well as the proximity of the municipal boundary with Boston that this is an appropriate district for development density consistent with transit oriented development schemes. For this reason, additional uses typical of transit oriented developments may be permitted under the criteria of this section, as long as such development is planned in a way consistent with other pedestrian-friendly commercial properties in Cleveland Circle.

Any applicant may seek relief under this Overlay District by Special Permit per Section 9.03 and Design Review by Section 5.09, provided it meets the following requirements within the Town of Brookline:

It contains a minimum of 40 Limited Service Hotel guest rooms.

The Floor Area Ratio of the proposed project shall be no less than 2.2 and no greater than 2.5.

For the purposes of this Overlay District, any proposed building shall be permitted to have more than one principal use. For example, a restaurant greater than 5,000 square feet under separate ownership and operation from a Limited Service Hotel may be located in the same building as the Limited Service Hotel without being considered as an accessory use, or as part of the Limited Service Hotel use.

Any application requesting relief under this Overlay District shall be subject to the following dimensional requirements, superseding any conflicting requirements in Article 5 of the Zoning By-law. Any other dimensional relief sought shall be pursued as per any other relevant sections of this Zoning By-law.

Maximum Floor Area Ratio: There is a strong desire for pedestrian-friendly uses along Chestnut Hill Avenue in this Overlay District, which has a grade change of more than 8' along this edge of the District. Therefore, with regards to calculating Gross Floor Area in this Overlay District, up to 10,000 square feet of area on the ground floor fronting Chestnut Hill Avenue may have finished floor to ceiling heights greater than 12', but no greater than 18', without requiring the Gross Floor Area to be calculated by multiplying this area by a factor greater than 1 where the floor to ceiling height exceeds 12'.

Setbacks and Build-to Lines:

Buildings shall not be greater than 15 feet nor less than 5 feet from the frontage of Chestnut Hill Avenue; and

Any portion of building within 50' of the frontage of Chestnut Hill Avenue that is above three stories shall be set back not less than 5 feet from lower floors, along all facades. For the purposes of this Overlay District, "Story" shall be defined as that portion of a building included between the upper surface of a floor and the upper surface of a floor or roof next above, whether or not such space is enclosed; and

Buildings shall be set back not less than 5 feet from the MBTA right-of-way.

The maximum height permitted is 56 feet;

Substantial rooftop structures such as observation towers, elevator penthouses and mechanical equipment shall not be located within 15' of the MBTA property line.

A screen fence along the property line with the MBTA right-of-way which exceeds a height of seven feet may be allowed by Special Permit granted by the Board of Appeals.

Parking requirements for Special Permit applications utilizing this Overlay District shall be as follows, superseding any conflicting requirements under Article 6:

Minimum Parking ratios:

Limited Service Hotel use: 0.5 parking spaces per hotel room

Retail use: 0.75 parking spaces per 1,000 g.s.f. of floor area

Restaurant use: 1 parking space per 1,000 g.s.f. of floor area

Office/Medical office use: 1 parking space per 1,000 g.s.f. of floor area

Subject to the approval of the Brookline Director of Transportation and Engineering, the required off-street loading facilities under Section 6.06.6 may be limited to the provision of 2 loading bays.

Any other parking relief sought shall be pursued as per any other relevant sections of this Zoning By-law.

The following traffic mitigation measures shall be required, subject to the review and approval of the Brookline Director of Transportation and Engineering:

Vehicle ingress and egress:

Vehicle ingress and egress to and from Chestnut Hill Avenue shall be via no more than one curb cut two lanes in width, controlled by a traffic signal. Such traffic signal shall include demand-actuated technology such that the light phase for egress from the Overlay District will not be triggered when there is no demand.

A segregated parking facility containing not less than 60 vehicle parking spaces shall be provided for the exclusive use of the Limited Service Hotel guests, visitors and employees. Vehicle egress for all users of this segregated parking facility shall be via the one-way rear exit roadway easement to Beacon Street. Both signage and physical barriers shall prohibit any vehicles entering the Limited Service Hotel segregated parking facility from exiting that facility back onto Chestnut Hill Avenue. To the extent a parking area is established to be shared by multiple uses, hotel users (except for taxicab/shuttle service vehicles and deliveries) parked in the shared parking area shall be required to exit the one way rear exit roadway to Beacon Street and other users shall exit via Chestnut Hill Avenue.

Vehicle egress for all uses other than that of the Limited Service Hotel and for taxicab/shuttle service vehicles and deliveries shall be via the single Chestnut Hill Avenue curb cut. All vehicles exiting the site onto Chestnut Hill Avenue must be able to make either a left or a right turn. No right turn on a red light shall be permitted from the site onto Chestnut Hill Avenue.

Taxicab stand and taxi pickup and drop-off shall be provided in an adjacent area on both the Brookline and the Boston segments of the site.

Final traffic design and mitigation shall be required and include the potential impact of the redevelopment of any directly abutting parcels, regardless of municipal boundaries. Specifically, the traffic design and mitigation shall allow for no more than a total of 110,000 square feet of Limited Service Hotel use; 48,000 square feet of office or medical office; and 18,000 square feet of restaurant or retail use.

Pedestrian improvements shall include:

Improvements to two pedestrian crossings across Chestnut Hill Avenue, including at Cleveland Circle as well as the crossing aligned with vehicular turn-around at the MBTA station south of the MBTA right-of-way. A third pedestrian crossing shall be provided where the signal for the Chestnut Hill Avenue entrance will be located, near the Boston/Brookline boundary, if approved by the Brookline Director of Transportation and Engineering as well as Boston Transportation Department.

Sidewalk improvements on the western side of Chestnut Hill Avenue shall include a minimum 10' wide sidewalk from the Brookline Boundary to the MBTA bridge and a replacement of sidewalk from the MBTA bridge to Clinton Road.

Noise. A required condition for any Special Permit under this Overlay shall be an enforceable agreement and/or condition to the Special Permit that requires the property owner to comply with the requirements any Noise By-law or ordinance of both Brookline and Boston, without regard to municipal boundaries.

Emerald Island Special District

The Emerald Island Special District - the area bounded by River Road, Brookline Avenue, and Washington Street - is an area in transition. It has been determined through study by the River Road Study Committee that specific zoning parameters are required to encourage appropriate redevelopment of this district. In developing these zoning parameters, due consideration has been given to the prominent location of this area as a major gateway to Brookline. The proximity of the Muddy River, Emerald Necklace, Longwood Medical Area as well as the differences in the scale of existing buildings, recently permitted and proposed developments, access to transit, and the solar orientation of sensitive nearby uses, including the residences of Village Way and Emerald Necklace Park all combined to shape the Special District parameters. Following a comprehensive study by financial, architecture, urban design and real estate experts, the Committee further concluded that the following concepts related to allowed uses, building heights, building form, parking requirements and the public realm are appropriate for this Special District.

Definitions. For the purposes of Section 5.06.4.j, the following terms shall have the listed definitions:

Micro Unit Dwelling: A building where a minimum of 50% of residential units measure no greater than 500 square feet in gross floor area. Buildings containing Micro Units may have flexible common areas for living and/or working.

Age Restricted Dwelling: A building where all residents are 62 years of age or older. Such units shall be subject to an age restriction described in a deed, deed rider, restrictive covenant, or other document in a form reasonably acceptable to Town Counsel that shall be recorded at the Registry of Deeds or the Land Court. Age and occupancy restrictions shall not preclude reasonable, time-limited guest visitation rights or accommodation for caretakers for the primary resident. The age and occupancy restrictions shall be enforceable solely against the violating unit and not the development as a whole, by the owner of one or more dwelling units or by the Town of Brookline. In the event of a violation, and at the request of the Town, the owner of the unit shall comply with the age and occupancy restrictions.

All applications for new structures, outdoor uses, and exterior alterations in the Emerald Island Special District which exceed a floor area ratio of 1.0, a height greater than 40' and/or seek alternative parking and loading zone requirements shall be permitted only on lots greater than 13,600 square feet in contiguous area and only for the uses described in Section 5.06.4.j.4, shall be subject to Site Plan Review by the Planning Board as described in Section 5.06.4.j.5, shall be subject to the requirements of Section 5.09, Design Review, shall obtain a special permit per Section 9.03, and shall meet the following requirements:

Setbacks and Sidewalk Widths:

All buildings shall be setback 10 feet from the mid-district drainage easement as shown in Figure 5.06.4.j.1 below.

ii.

All buildings shall be setback 45 feet from the Point of Intersecting Tangents of Brookline Avenue and River Road as shown in Figure 5.06.4.j.2 below.

iii.

Notwithstanding Section 5.01 and other than as provided in Sections 5.06.4.j.3.a.i and 5.06.4.j.3.a.ii, there shall be no additional setback requirements except as is necessary to achieve the required sidewalk widths for the district. For the purposes of the EISD only, sidewalk shall be defined as the area between the building facade and the face of the curb. The required sidewalk width shall be measured from the ground level of the proposed building facade to the face of the curb at the time of special permit application. All sidewalks shall maintain a minimum 5 foot wide walkway clear from all obstructions, including, but not limited to tree pits, structural columns and street furniture. The minimum sidewalk width along Brookline Avenue and River Road shall be no less than 12 feet. The minimum sidewalk width along Washington Street shall be no less than 10 feet.

iv.

Where it can be demonstrated that achieving the required sidewalk width would be infeasible in limited areas, the Board of Appeals may by special permit reduce the required width of the affected areas to no less than 8 feet on Washington Street and River Road. No relief may be granted for a reduction in sidewalk width along Brookline Avenue. Applicants for a special permit to reduce the width of a sidewalk shall provide written and graphic documentation to the Planning Board illustrating why the required width is not attainable in the affected area. The Planning Board may in an affirmative and written determination make a recommendation to the Board of Appeals to reduce the width of the sidewalk in limited areas. Where relief is granted, applicants shall provide counterbalancing amenities in the form of wider sidewalks and/or landscaping on-site or in the immediate area adjacent to their site, subject to the review and approval of the Planning Board.

The construction or renovation of such buildings consistent with these plans shall be confirmed prior to the issuance of a Certificate of Occupancy.

Street trees shall be provided at regular intervals approximately every 25 feet along the sidewalks of Brookline Avenue, Washington Street and River Road. The size, location and species of all trees at the time of planting and the final design of all landscaping in the public way shall be approved by the Director of Parks and Open Space or his/her designee. In circumstances where trees cannot be provided as stipulated above as determined by the Director of Parks and Open Space or his/her designee, the applicant shall provide an equivalent amount of trees and/or landscaping at appropriate locations on the site or make a financial contribution to the Town in an equivalent dollar amount for similar improvements in adjacent parks and public spaces.

The applicant shall devote no less than 1% of the hard construction cost of constructing its project, (including any building, site work, above ground or underground structures, but exclusive of tenant fit-up) to making off-site, streetscape and parks improvements within 500 feet of the Special District boundaries. In addition to review by the Planning Board, a plan of the proposed off-site improvements shall be submitted for the review and approval of the Director of Transportation and the Director of Parks and Open Space or their designees. Alternatively, with the approval of the Director of Transportation and the Director of Parks and Open Space, the applicant may make a financial contribution to the Town in an equivalent dollar amount to be used by the Town for such purposes.

Public seating and pedestrian-scale lighting shall be provided at regular intervals. The location, number and design of all seating and lighting in the public way shall be approved by the Director of Parks and Open Space or his/her designee.

Notwithstanding the provisions of Sections 6.06.6 and 6.07, the number and size of required loading zones may be reduced in accordance with Site Plan Review as noted in Section 5.06.4.j.5 below.

A building shall not have more than 30% of its frontage along a street devoted to residential use including associated lobby use.

Any proposed building shall be permitted to have more than one principal use. For example, a restaurant or retail business may be located in the same building as a permitted residential, or office, or hotel use without being considered an accessory use.

Exceptions to Maximum FAR and Maximum Height

Additional height may be granted by special permit up to 85 feet for buildings primarily containing Micro Unit Dwellings, Age Restricted Dwellings or the following uses: 6 (Multiple or attached dwelling of four or more units), 6B (Dwelling, Live/Work Space); 8 (Hotel); 8A (Limited Service Hotel); 20 (Medical Office); 21 (Professional Office); 29 (Store less than 5,000 SF), 30 (Eating Place less than 5,000 SF); 33 (Stores not exceeding 10,000 SF); 33a (Stores over 10,000 SF); 34 (Place for the sale and consumption of food and beverages exceeding 5,000 SF); 66 (Accessory Laboratory), only for buildings located a minimum of 189.12 feet from the intersection of Washington Street and Brookline Avenue, provided that the footprint of any building mass above a height of 65 feet covers no more than 55% of the lot area. Buildings may also contain Principal Uses 18A (Small Group Health/Fitness), 20a (Licensed Veterinarian), and 32 (Service Business) provided that such uses occupy no more than 25% of the building. The required 189.12 foot distance from the intersection of Washington Street and Brookline Avenue shall be measured from the Point of Intersecting Tangents as show in Figure 5.06.4.j.3 below.

Additional height of up to 110 feet may be granted by special permit for buildings containing only the following uses: 8 (Hotel) and 8A (Limited Service Hotel) and only for buildings with frontage on Washington Street provided that the footprint of any building mass covers no more of the lot area than is specified in Table 5.06.4.j.1 and as depicted in Figure 5.06.4.j.4 below. Where an applicant can demonstrate that additional lot coverage for any building mass above 35 feet would result in an improved building design, the Board of Appeals may by special permit grant an increase in the maximum percentage of lot coverage as shown in Table 5.06.4.j.1 below. Applicants for a special permit to increase the maximum percentage of lot coverage shall provide written and graphic documentation to the Planning Board and Design Advisory Team illustrating how the building design has improved. The Planning Board may in an affirmative and written determination make a recommendation to the Board of Appeals to increase the maximum percentage of lot coverage as shown in Table 5.06.4.j.1 below. The Design Advisory Team shall provide a similar affirmative written recommendation.

Table 5.06.4.j.1 Maximum % Lot Area Coverage by Building Height
Building Mass Heights	Maximum % Lot Area Coverage	Maximum % Lot Area Coverage By Special Permit with Planning Board Recommendation

FIGURE 5.06.4.j.4 Maximum % Lot Coverage by Building Height

Parking and Vehicular Requirements:

Notwithstanding Section 6.02, there shall be no minimum parking requirements for the following uses and such uses shall have the maximum parking limits noted in Table 5.06.4.j.2 below.

Notwithstanding the above, where it can be demonstrated that additional parking is needed, the Board of Appeals may by special permit increase the maximum parking ratio by no more than 20%. Applicants for a special permit to increase the maximum parking ratio shall provide written documentation to the Planning Board demonstrating the need for additional parking. The Planning Board may in an affirmative and written determination make a recommendation to the Board of Appeals to increase the maximum parking ratio by no more than 20%.

Notwithstanding the above, dedicated spaces for Car Sharing Organizations (CSO) may be provided without regard to such maximum parking limits. If such dedicated parking spaces are not leased by any CSO they shall be dedicated to bicycle parking and appropriate bicycle parking hardware shall be provided.

Table 5.06.4.j.2 - Maximum Parking Limits
USE	MAXIMUM PARKING
Principle Use 6 (Multiple or attached dwelling of four or more units) and Age Restricted Dwelling	1.25 per unit
Principal Use 6B (Live/Work space)	0.50 per unit
Micro Unit Dwelling	0.50 per unit
Principal Use 8 (Hotel) and 8a (Limited Service Hotel)	0.40 per room
Principal Uses: 18A (Small group health/fitness); 20 (medical office); 20a (Licensed veterinarian); 21 (professional office); 29 (store less than 5,000 SF); 30 (Eating places less than 5,000 SF); 32 (Service use business); 33 (Stores not exceeding 10,000 SF); 33a (Stores over 10,000 SF); 34 (Place for sale and consumption of food not exceeding 5,000 SF); 66A (Accessory Laboratory)	1.50 per 1,000 SF

Design Standards:

Building facades parallel to or within 45 degrees of parallel to any property line shall be designed and constructed with equal care and quality. Visual articulation shall be achieved for each facade by (a) employing variations in materials and/or ensuring that no portion of any such facade is coplanar or unbroken for more than 3,500 square feet without a change in depth of 2 feet or more, or (b) utilizing alternative methods of vertical or horizontal articulation, or (c) utilizing other design elements that, in the affirmative and written determination of the Design Advisory Team provide equivalent or better visual relief with respect to building massing, for the reasons expressed in such written determination. The Planning Board and the Board of Appeals shall provide a similar written determination and reasons with respect to facade design. During their review of all proposed building designs, both the Design Advisory Team and Planning Board shall consult the Emerald Island Special District Design Guidelines developed by the River Road Study Committee for guidance on general exterior massing, scale and design.

In order to minimize visual and audible impacts, all rooftop mechanical equipment shall be insulated and screened to the greatest extent possible from all public ways via substantial screening materials and/or shall be located in the interior of the building. Additionally, all rooftop mechanical equipment shall be located such that all shadow impacts are minimized.

Waldo-Durgin Overlay District

It has been determined through study of the northeast block of Coolidge Corner that potential exists for careful, planned redevelopment. It has further been determined that, due to the circulation patterns as well as the adjacency of this area to cultural anchors, retail businesses, transit systems and residential neighborhoods, a mix of residential and commercial uses are appropriate. Significant improvements to the pedestrian realm, the provision of publicly accessible amenities for the neighborhood, sustainability improvements and the preference for parking infrastructure to be located underground are all reasons why additional density may be allowed by Special Permit under the criteria of this section.

At any point prior to June 1, 2020, an applicant may seek relief by Special Permit under this Overlay District by completing the Design Review preapplication process as set forth in Section 5.09(3)(a)(2) provided the proposed project includes the following requirements and limitations:

Includes a minimum of 57,000 square feet of contiguous land

Includes a Hotel component with at least 160 rooms.

The Board of Appeals may grant a Special Permit under this section allowing for a project that meets the following requirements and limitations. Conformance with said requirements and limitations shall be made conditions of the Special Permit.

The project must contain a minimum of 12% Open Space. For the purposes of this requirement, Open Space shall include parts of a Lot at ground level that meet one or more of the following criteria: contiguous landscaped areas that are at the least 200 square feet in size; and walkways open to the public that include planted containers, landscaped beds, and/or street trees.

Parking

All parking structures shall be located underground and shall be a maximum of 115,000 gross square feet in size.

ii.

The number of parking spaces required per Article 6 of the Zoning By-Law may be reduced at the request of the applicant, following review of a parking study and favorable recommendation by the Planning Board.

iii.

Parking Infrastructure Flexibility – To encourage the reduction of vehicle use over time, an applicant may seek a modification to any Special Permit granted under Section 5.06.4.k to both reduce the number of required spaces and convert the use from underground parking to other allowed uses, subject to all other provisions of the By-Law with respect to use, as long as updated traffic and parking studies demonstrate those parking spaces are no longer needed. Any such below ground space, whether or not it is habitable, shall be excluded from the maximum Floor Area Ratio calculations.

iv.

Any fees charged for parking must be separate from any rental, lease, sale, employment, contract or other arrangement permitting a user to occupy the building.

The Gross Floor Area Ratio for a project permitted pursuant to this section shall not exceed 6.0. If a Special Permit application includes less than 86,250 square feet of underground parking infrastructure, then, in addition to the review processes described in Section 5.09 (Design Review) the applicant shall, prior to submitting a Special Permit application, request a public hearing with the Economic Development Advisory Board (EDAB) to review the financial feasibility of the project. Based on the information presented by the applicant and/or EDAB’s consultant(s), if any, EDAB may make a recommendation to the Planning Board and Board of Appeals as to whether the Floor Area Ratio is justified.

The maximum building height may be 160’ for portions of a building that are within 180’ of Pleasant Street and 110’ of John Street; otherwise, the maximum building height is 125’. These maximum building heights do not include rooftop structures such as elevator penthouses and mechanical equipment. Building heights shall be measured from the District Record Grade rather than as prescribed in Section 5.30. The District Record Grade shall be the record grade of Pleasant Street at the edge of pavement opposite the midpoint of the Pleasant Street boundary of the Waldo-Durgin Overlay District.

Figure 5.06.4.k.1 – Height of Building Measurements in the

Waldo-Durgin Overlay District

The residential component of the project shall not include more than 132 units that do not meet the Affordable Unit definition in Section 4.08(2)(c) nor shall it contain more than 13 habitable, above-ground stories of primarily residential use.

The non-residential component of the project shall not contain more than 10 habitable, above-ground stories.

No rear yard is required. The above-ground portion of any building shall be setback at least 10’ from the property line bordering John Street.

Use Flexibility

The ground floor use along the entire length of Pleasant Street may only include the following uses as defined and regulated in Section 4.07, Table of Use Regulations: entertainment and recreation facility (Use 16), certain retail uses (Uses 29, 33, 33A), restaurants (Uses 30 and 34), and office (Use 35). Additionally, the building use along Pleasant Street must include at least one retail (Use 29, 33, or 33A), or restaurant (Use 30 or 34) space that is at least 30’ wide along Pleasant Street and a minimum of 1,200 square feet in floor space.

ii.

The ground floor of a residential building may have maximum frontage along a street that exceeds the 40% maximum in Use 6 in Section 4.07 - Table of Use Regulations, if the applicant adequately demonstrates that: (i) the location of residential and non-residential uses of the ground floor are appropriate given the transition between residential and commercial neighborhoods; and (ii) the average frontage for the first floor is no more than 75% residential.

iii.

Any proposed building shall be permitted to have more than one principal use. For example, a restaurant or retail business may be located in the same building as a permitted residential or hotel use without being considered an accessory use.

Any application including new structures that seeks relief under this Overlay District Special Permit shall:

be subject to Site Plan Review by the Planning Board to ensure that there is adequate provision of access for fire and service equipment; ensure adequate provision for utilities and storm water storage and drainage; ensure adequate provision of loading and passenger pick-up zones; ensure adequate provision of parking; minimize impacts on wetland resource areas; minimize storm water flow from the site; minimize soil erosion; minimize the threat of air and water pollution; minimize groundwater contamination from on-site disposal of hazardous substances; maximize pedestrian, bicycle and vehicle safety; screen parking, storage and outdoor service areas through landscaping or fencing; minimize headlight and other light intrusion; ensure compliance with the Brookline Zoning By-Laws; maximize property enhancement with sufficient landscaping, lighting, street furniture and other site amenities; minimize impacts on adjacent property associated with hours of operation, deliveries, noise, rubbish removal and storage. All plans and maps submitted for site plan review shall be prepared, stamped, and signed by a Professional Engineer licensed to practice in Massachusetts. Pursuant to the site plan review process, applicants shall provide to the Planning Board and the Director of Engineering a site plan showing:

Demonstrated design compliance with any General By-Law related to erosion and sediment control and stormwater management;

ii.

Property lines and physical features, including roads, driveways, parking for vehicles and bicycles, loading areas and trash storage for the project site; and

iii.

Proposed changes to the landscape of the site, grading, vegetation clearing and planting, and exterior lighting.

be deemed a Major Impact Project with respect to Section 5.09, Design Review.

include as a condition of the special permit a Transportation Access Plan Agreement ("TAPA") approved by the Director of Transportation that includes Transportation Demand Management ("TDM") programs and an annual report review process. All owner(s) of the property or properties subject to the special permit shall submit an annual report for review and approval to the Director of Transportation relative to the implementation and effectiveness of the TAPA. The Director of Transportation in consultation with the Director of Planning and Community Development shall determine whether the TAPA is working satisfactorily or whether reasonable modifications to the TAPA are required. The TAPA shall be modified to incorporate any reasonable requests of the Director of Transportation within 60 days after they issue their determination. Failure to issue such a determination within 60 days of receiving the annual report shall be deemed acceptance of the report and existing provisions of the TAPA. If any owner objects to any new request as being unreasonable or not required, such matter may be presented to the Transportation Board for recommendation to the Board of Appeals for determination.

Allowing the additional density through the Special Permit contemplated by this Section has a potential benefit contemporaneous with its inclusion in the By-Law. However, planning objectives potentially achieved by this Section may not be met if substantial time elapses. Therefore, if upon closing the public hearing on a Special Permit under Section 5.06.4.k, the Board of Appeals finds: (a) more than two years has elapsed since the opening of the public hearing; and (b) the amount of elapsed time is, in the discretion of the Board, excessive and contravenes the planning objectives of Section 5.06.4.k, the Board may deny the request for a Waldo-Durgin Overlay District Special Permit.

Fisher Hill Special Overlay District

It has been determined through study of the former Newbury College campus that the potential exists for careful, planned redevelopment. It has further been determined that, due to the surrounding residential development pattern, and the municipal need for housing for an aging population, assisted living residential uses in a life care facility designed with a similar architectural character as the neighborhood are appropriate. Benefits to the community include maintenance for adaptive reuse of the Mitton House and creating a public easement along Fisher Avenue to preserve mature shade trees, and are significant reasons for why additional density may be allowed by Special Permit under the criteria of this section.

At any point prior to December 31, 2020, an applicant may seek relief by Special Permit under this Overlay District by completing the Design Review preapplication process as set forth in Section 5.09 (3)(a)(2) provided the proposed project includes the following requirements and limitations:

Includes a minimum of three acres of contiguous land.

Includes a life care facility with a maximum of 160 units as its primary use including all related accessory uses.

Open Space

The project must dedicate a minimum of 40% of lot area towards Open Space. For the purposes of this requirement, Open Space shall include parts of a lot at ground level that are contiguous landscaped areas and walkways that include planted containers, landscaped beds, and/or street trees. Usable open space is not a requirement for this use.

ii.

The open space requirements of Table 5.01 — Table of Dimensional Requirements may be reduced in accordance with Site Plan Review as noted in Section 5.06.4.1.4 below.

Parking

98 parking spaces shall be provided with a minimum of 43 concealed.

ii.

iii.

Parking area setback along the southern lot line shall be no less than 20 feet.

iv.

The parking and drive requirements under Section 6.04, including stall width and depth, aisle width, and width of entrance and exit drives, may be modified in accordance with Site Plan Review as noted in Section 5.06.4.1.4 below.

Once a minimum of five years have passed since the issuance of a Certificate of Occupancy for any project promulgated pursuant to a Special Permit granted under this Section, the holder of said Special Permit may seek modification of the Special Permit to allow the provision of fewer than 98 spaces, but only through a reduction in the number of non-concealed parking spaces and only upon a showing to the Zoning Board of Appeals that such a reduction will not impact the neighborhood.

The Gross Floor Area Ratio for a project permitted pursuant to this section shall not exceed 1.15.

From the rear lot line, no less than 50 feet.

Refer to Building Height and Setback Diagram.

Accessory Structures allowed within the site setbacks include retaining walls, fencing, and utility equipment- ie generator and transformer. Setback for all structures is 6' min. from any lot line. Where required for emergency vehicle access, retaining walls and fencing can encroach on front yard setbacks.

Notwithstanding the provisions of Section 6.06.6, the number and size of required loading zones may be reduced in accordance with Site Plan Review as noted in Section 5.06.4.l.4 below. If the loading zone includes an area for trash and recycling this area for trash and recycling shall be enclosed. If the entire loading zone including the area for trash and recycling is fully enclosed, such area shall not count towards the project's total gross floor area.

Design Standards: During their review of all proposed building designs, both the Design Advisory Team and Planning Board shall consult the Fisher Hill Special District Design Guidelines developed by the Newbury Zoning Committee for guidance on general exterior massing, scale and design.

Any application including new structures that seeks relief under this Overlay District shall:

be subject to Site Plan Review by the Planning Board to ensure that there is adequate provision of access for fire and service equipment; ensure adequate provision for utilities and storm water storage and drainage; ensure adequate provision of loading zones; ensure adequate provision of parking; minimize impacts on wetland resource areas; minimize storm water flow from the site; minimize soil erosion; minimize the threat of air and water pollution; minimize groundwater contamination from on-site disposal of hazardous substances; maximize pedestrian, bicycle and vehicle safety; screen parking, storage and outdoor service areas through landscaping or fencing; minimize headlight and other light intrusion; ensure compliance with the Brookline Zoning By-Laws; maximize property enhancement with sufficient landscaping, lighting, street furniture and other site amenities; minimize impacts on adjacent property associated with hours of operation, deliveries, noise, rubbish and recycling removal and storage. All plans and maps submitted for site plan review shall be prepared, stamped, and signed by a Professional Engineer licensed to practice in Massachusetts. Pursuant to the site plan review process, applicants shall provide to the Planning Board and the Director of Engineering a site plan showing:

Demonstrated design compliance with any General By-Law related to erosion and sediment control and stormwater management;

ii.

Property lines and physical features, including roads, driveways, parking for vehicles and bicycles, loading areas and trash storage for the project site; and

iii.

Proposed changes to the landscape of the site, grading, vegetation clearing and planting, and exterior lighting.

be deemed a Major Impact Project with respect to Section 5.09, Design Review.

Allowing the additional density through the Special Permit contemplated by this Section has a potential benefit contemporaneous with its inclusion in the By-Law. However, planning objectives potentially achieved by this Section may not be met if substantial time elapses. Therefore, if upon closing the public hearing on the Special Permit contemplated herein, the Board of Appeals finds: (a) more than two years has elapsed since the opening of the public hearing; and (b) the amount of elapsed time is, in the discretion of the Board, excessive and contravenes the planning objectives of this Section, the Board may deny the request for a Special Permit.

§ 5.07 DWELLINGS IN BUSINESS AND INDUSTRIAL DISTRICTS

Dwellings in business and industrial districts shall conform to the minimum usable open space and minimum side and rear yard requirements of the M district with the same maximum permitted floor area ratio as the business or industrial district in which the dwelling is located or of the M-2.0 district for dwellings in G-1.75 districts. However, if the Board of Appeals finds that a waiver of such dimensional requirements would promote reasonable development of the site compatible with adjacent buildings and the surrounding area, the Board may waive such requirements by special permit.

§ 5.08 EXCEPTIONS TO DIMENSIONAL REQUIREMENTS FOR USES 9 & 10

The floor area ratio requirements as applied to Uses 9 and 10 listed in § 4.07 shall be less restrictive than as specified in Table 5.01 in the following respects:

Where several lots in the same ownership and also in the same use district are separated from each other only by an adjacent street or intersecting adjacent streets, the area of all such lots may be aggregated in calculating floor area ratio.

The floor area ratio shall be increased by one per cent for each 2,000 square feet of lot area exceeding the lot size minimum for the district under consideration, up to a maximum of 65 percent.

Under a special permit the Board of Appeals may permit further modifications in the dimensional requirements specified in Article V as applied to Uses 9 and 10 to the extent necessary to allow reasonable development of such a use in general harmony with other uses permitted and as regulated in the vicinity.

§ 5.09 DESIGN REVIEW

Purpose

The purpose of this section is to provide individual detailed review of certain uses and structures which have a substantial impact upon the character of the Town and upon traffic, utilities and property values therein, thereby affecting the public health, safety and general welfare thereof. The design review process is intended to promote the specific purposes listed in § 1.0, paragraph 1. of this By-law.

Scope

In the following categories all new structures and outdoor uses, exterior alterations, exterior additions, and exterior modifications or changes, including exterior demolitions, which require a building permit from the building department under the Building Code, shall require a special permit subject to the community and environmental impact and design review procedures and standards hereinafter specified. Exterior alterations, exterior additions and exterior changes (except as provided below), including fences, walls, and driveways, to residential uses permitted by right in S, SC, T, and F districts; signs as regulated in §§ 7.02, and 7.03; and regulated facade alterations as defined and regulated in § 7.06 shall be exempt from the requirements of this section.

Any structure or outdoor use on a lot any part of which is located in the G-1.75(CC) or L-0.5 (CL) Districts or which fronts on or is within 100 feet of: Beacon Street, Commonwealth Avenue, Boylston Street, Harvard Street, Brookline Avenue, or Washington Street.

attached dwellings in groups of three or more

designed groups of single-family dwellings as per § 5.11, paragraph 2.

multiple dwellings with four or more units on the premises, whether contained in one or more structures

lodging houses and hotels

gasoline service stations

outdoor automobile sales and storage for sales

Procedure

General

Site Disturbance and Clearing — Pursuant to § 3.c.2) and § 4.a. of this Article, the applicant seeking a special permit or variance shall maintain all existing trees and other site features until a special permit or variance is approved.

In the event that site excavation, grading or clearing of trees and vegetation does occur on a property that is the subject of a pending application for a Special Permit or Variance, the Planning Board or Board of Appeals may take the following actions:

Request in writing that the Building Commissioner order the applicant to stop work and cease all activities associated with excavating, grading, or tree and vegetation clearance.

Request that the applicant engage the services of a Massachusetts Certified Arborist to inspect the subject property and file a written report with the Town's Tree Warden detailing the following:

The nature and extent of the excavating, grading or clearing trees and vegetation that has occurred, including the species and caliper size of the trees and plant material removed, where possible.

Preliminary recommendations, to the extent practicable, that will either restore the site or introduce replacement trees and landscape features as part of the landscape plan.

Based on the report and preliminary recommendations from the Director of Planning and Community Development, the Board of Appeals may, as part decision on an application for a Special Permit or Variance, include conditions that will require, to the extent practicable, the restoration or replacement of trees, landscape and other site features.

Either prior to or following the filing of an application for a Special Permit or Variance with the Town Clerk, the applicant may submit to the Building Commissioner, a request to proceed with limited site disturbance or clearing necessary to conduct site surveys and other routine predevelopment investigations not associated with routine property maintenance. The request shall be in a form prescribed by the Building Commissioner. Upon receipt, the Building Commissioner shall convey the request to the Director of Planning and Community Development, Tree Warden and Planning Board. The Planning Board, in consultation with the Director of Planning and Community Development and Tree Warden, shall have 14 days to either recommend approval, approval with conditions or denial of the request. The applicant may appeal the determination of the Planning Board to the Board of Appeals.

Preapplication — Prior to a formal submission to the Building Commissioner, the applicant is strongly encouraged to take the following steps, and in the case of a Major Impact Project as defined in Section 5.09 3.b. such preliminary steps are required:

consult with the Building Commissioner and Planning Director or their designees for technical advice relative to the community and environmental impact and design review standards of this section; and

schedule and hold at least one neighborhood meeting and make good faith effort to notify in a timely manner abutters, tenants of abutters, Town Meeting Members for the precincts of all abutters, neighborhood associations, and other interested citizen groups to review the project plans, and the applicant should actively promote citizen involvement throughout the review process. Timely notification requires notices to be mailed or delivered at least seven days prior to the scheduled neighborhood meeting. Failure to provide timely notice for a Major Impact Project shall require scheduling of another meeting with timely notice. In the case of Major Impact Projects, the meeting shall be convened prior to the Planning Board's preliminary meeting as required by Section 5.09 3.b.4). The Department of Planning and Community Development will assist the applicant in identifying the parties to be notified; and

meet with the Planning Director or their designee to determine if the Planning Board has adopted design guidelines which pertain to the proposed project; and

meet with the Transportation Director and the Planning Director or their designees for advice on the preparation of any required transportation studies; and

meet with the Town's Tree Warden and/or Tree Planting Committee if either the removal or relocation of existing public shade trees or the planting of new public shade trees is proposed. Removal of public shade trees is governed by Massachusetts General Law Chapter 87.

Application — Applications for uses subject to community and environmental design review shall be submitted to the Building Commissioner and to the Board of Appeals in accordance with the procedure for special permits specified in §§ 9.03 and 9.04, including the requirements for public notice and hearing and referral to the Planning Board. The report of the Planning Board to the Board of Appeals shall contain a specific evaluation or statement in relation to each of the following:

fulfillment of the preapplication phase of this section;

designation of the proposal as a major impact project (or exemption as such) as defined in paragraph 3., of this section;

conformance with each of the standards listed in paragraph 4. of this section; and

conformance with the goals and objectives of the Comprehensive Plan.

conformance with the Affordable Housing requirements in § 4.08, where applicable.

The Board of Appeals shall not deny a special permit for any use or condition which requires a special permit solely because it falls into one of the categories listed in § 4.01, paragraph 3., unless it finds that the use or condition departs from the standards listed in paragraph 4. of this section to such an extent as to produce a serious adverse impact upon the character of the area or upon traffic, utilities and property values therein, thereby adversely affecting the public health, safety, and general welfare. In reviewing applications under this section, the Board of Appeals may require modifications, conditions and safeguards reasonably related to the community and environmental impact and design standards of this section.

Major Impact Projects Only — Prior to formal submission of an application to the Building Commissioner pursuant to this section, the applicant shall consult with the Planning Director and the Building Commissioner or their designees to determine whether such application involves a major impact project which shall be defined as any residential development of 16 units or more, any nonresidential development containing more than 25,000 square feet, or any other project with the potential for substantial environmental impact on the community. If the proposal is deemed by either official to be a major impact project, then the following procedural requirements shall be completed prior to the filing of an application with the Building Commissioner.

The applicant shall meet informally with the Planning Director and the Building Commissioner to discuss the development program and the relevant Zoning By-law requirements.

The applicant shall submit to the Planning Director or their designee a program statement and zoning analysis of the proposed project, schematic site plan, massing model with a photo of the model, and perspective massing studies prior to a preliminary review by the Planning Board. If a floor area bonus is proposed, the applicant shall first present material for a proposal without any bonus and then an alternative with the bonus, indicating the public benefit features possible, if the bonus is granted.

The Planning Director or their designee shall, in the normal course of notification of the Planning Board's preliminary meeting on the project, send the program statement, zoning analysis, and schematic site plan to the following departments and boards: Building, Engineering/Transportation, Fire, Police, Public Works, Conservation Commission, Economic Development Advisory Board, Preservation Commission, Tree Planting Committee and, if a residential development, the Housing Advisory Board. The enumerated departments and commissions and any other entities with an interest in the project may at their discretion submit in writing a statement of their concerns and recommendations to the Planning Board and Board of Appeals.

The Planning Board shall review these materials at a regular Planning Board meeting and shall issue an initial report to the applicant within three weeks of the preliminary meeting. Once the basic environmental aspects of the proposal, and in the case of a residential development project of sixteen units or more, the affordable housing aspects of the proposal, are reviewed by the Planning Board, the applicant may proceed with a formal submission to the Building Commissioner.

All § 5.09 Projects — To aid the Board of Appeals in making the findings required in § 9.05 and the Planning Board in preparing the advisory report provided in § 9.04, the applicant shall submit the following materials in addition to the usual drawings at the time of application to the Building Commissioner:

Model — An inexpensive study model or final presentation model at a minimum scale of 1 inch equals 20 feet showing the tract, abutting streets, proposed contours, proposed buildings, and the massing of abutting buildings. (Not required for additions, alterations, or changes which increase gross floor area by less than 100%.)

Drawing of Existing Conditions — A drawing showing the location, type, size, or dimension of existing trees, rock masses, and other natural features with designations as to which features will be retained. In order to meet the conditions for approval of a special permit as specified in § 9.05 all existing trees, rock masses, and other natural features shall be retained until a special permit is approved. The location of existing public shade trees situated within the public right-of-way adjoining the subject property shall also be located on the drawing if any modification to the public sidewalk or a new or modified curb cut is proposed or required.

Drawing of Proposal

Structure — A drawing including color and type of surface materials showing front and rear elevations, and side elevations where there are no adjoining buildings, and floor plans.

Landscaping — A drawing showing the location, dimensions, and arrangements of all open spaces and yards, including type and size of planting materials, color and type of surface materials, methods to be employed for screening, and proposed grades.

Photographs — Photographs showing the proposed building site and surrounding properties, and of the model (if required). Applications for alterations, modifications and additions shall include photographs showing existing structure or sign to be altered and its relationship to adjacent properties.

Impact Statement — A statement by applicant with explanation of how each of the community and environmental impact and design standards is incorporated into the design of the proposed development. In cases, where construction is located within 50' of a public shade tree, the method that will be used to protect the tree during construction shall be submitted for review and approval of the Tree Warden. Where a particular standard is not applicable, a statement to that effect will suffice. An environmental impact statement prepared in accordance with state or Federal regulations may be accepted as a substitute in lieu of this statement.

Transportation Studies — Certain projects which, due to their size, use characteristics or location, may have a significant impact on traffic require the preparation of transportation studies. The following development threshold levels indicate the nature of studies required. However, additional studies may be required for projects of any size which the Transportation Director or the Planning Director consider may have substantial environmental effects on the community. Any required transportation studies must be prepared in accordance with the Transportation Access Plan Guidelines issued by the Transportation Department. An access Plan should include a transportation impact analysis and, as warranted, a proposed package of mitigation measures. Impact mitigation measures may include-but should not be limited to: construction management; traffic mitigation and encouragement of transit use; parking management; transit improvements; number and location of bicycle parking and storage facilities; parking and access for delivery and service vehicles, pedestrian amenities, and capital improvements.

Projects with more than 10,000 square feet of non-residential space or 10 dwelling units shall require the preparation of a Project Summary and Project Description.

Projects with more than 25,000 square feet of non-residential space or 25 dwelling units shall require the preparation of a Transportation Impact Study and Access Plan and may require the preparation of an Access Plan Agreement.

Projects over 100,000 square feet of non-residential space or 100 residential units shall require the preparation of a Transportation Impact Study and an Access Plan Agreement.

Parking resulting from a Transportation Access Plan Agreement shall receive an annual permit from the Building Department. The permit shall require the fulfillment of all elements of the Transportation Access Plan.

Design Advisory Teams

The Planning Board is authorized to appoint a Design Advisory Team (DAT) to assist it in design review of any project that requires a special permit under Section 5.09, Design Review. In the case of a Major Impact Project, or substantial modification as determined by the Building Commissioner or Planning and Community Development Director to a Major Impact Project, the Planning Board shall appoint a DAT. DAT review of a project shall be coordinated with any other applicable review of the same project by other Town Boards and Commissions. The DAT shall consist of the following: one or more Planning Board member(s); professional architect(s), landscape architect(s) or other design related professional(s); and one or more neighborhood representatives. The DAT will provide professional design review assistance to the Planning Board and the Planning and Community Development Department in review of certain § 5.09 projects which may have a significant impact on the character of the area. The Planning Board may, in its discretion, also appoint representatives from other appropriate Town boards and commissions to serve on a DAT, when deemed necessary to insure coordinated project review. The Planning Board shall appoint a DAT at a regularly scheduled meeting where public notice has been provided pursuant to Section 9.08. At the direction of the Planning Board, the applicant may be required to meet with the DAT to discuss resolution of design concerns. Following a meeting with the DAT, the applicant must include in any further submissions its responses to issues raised by the DAT. The DAT may also submit a report to the Planning Board and the Board of Appeals for consideration.

Plan Revisions

Any plans revised after a formal application has been made to the Building Commissioner shall be submitted in triplicate to the Building Commissioner prior to the Board of Appeals hearing. Once the Board of Appeals public hearing on the proposal is closed, any plan revision, other than a change governed by a condition of the Board of Appeals approval, which in any way affects or alters the visual appearance of the facade, roof, or cornice line, or modifies the site plan, shall be reviewed by the Building Commissioner and the Planning Director, or their designees. If such revision is deemed by either the Building Commissioner or Planning Director to constitute a change other than a minor modification, the matter shall be referred to the Planning Board for its recommendation in accordance with the community and environmental impact and design review standards of this section and to the Board of Appeals for any action it deems appropriate.

Community and Environmental Impact and Design Standards

The following standards shall be utilized by the Board of Appeals and Planning Board in reviewing all site and building plans. These standards are intended to provide a frame of reference for the applicant in the development of site and building plans as well as a method of review for the reviewing authority. These standards shall not be regarded as inflexible requirements. They are not intended to discourage creativity, invention and innovation. The specification of one or more particular architectural styles is not included in these standards. The standards of review outlined in paragraphs a. through o. below shall also apply to all accessory buildings, structures, freestanding signs and other site features, however related to the major buildings or structures.

Preservation of Trees and Landscape — Trees and other landscape features shall be preserved in a natural state, insofar as practicable, by minimizing tree and soil removal, and any grade changes shall be in keeping with the general appearance of neighboring developed areas. Public shade trees within the public right-of-way are governed by Massachusetts General Law Chapter 87 and, where feasible, shall be preserved and the appropriate addition of such trees is encouraged.

Relation of Buildings to Environment — Proposed development shall be related harmoniously to the terrain, trees, landscape, and natural features. The Board of Appeals may require a modification in massing so as to reduce the effect of shadows on abutting property or on public open space and public streets.

Relation of Buildings to the Form of the Streetscape and Neighborhood — Proposed development shall be consistent with the use, scale, massing, height, yard setbacks and architecture of existing buildings and the overall streetscape of the surrounding area including existing abutting buildings and existing buildings that conform to the zoning by-law on lots of similar size in the neighborhood. The Board of Appeals may require a modification in massing, scale, height, setbacks or design so as to make the proposed building more consistent with the form of such existing buildings and the existing streetscape, and may rely upon data gathered that documents the character of the existing streetscape in making such a determination. Examples of changes that may be required include addition of bays or roof types consistent with those nearby; alteration of the massing, scale, setbacks and height of the building to more closely match such existing buildings and the existing streetscape, or changes to the fenestration. The street level of a commercial building should be designed for occupancy and not for parking. Unenclosed street level parking along the frontage of any major street as listed in paragraph 2., subparagraph a. of this section is strongly discouraged. Otherwise, street level parking should be enclosed or screened from view.

Open Space — All open space (landscaped and usable) shall be so designed as to add to the visual amenities of the vicinity by maximizing its visibility for persons passing the site or overlooking it from nearby properties. The location and configuration of usable open space shall be so designed as to encourage social interaction, maximize its utility, and facilitate maintenance. All landscaped open space shall be continuously maintained.

Circulation — With respect to vehicular, bicycle and pedestrian circulation, including entrances, ramps, walkways, drives, and parking, special attention shall be given to location and number of access points to the public streets (especially in relation to existing traffic controls and mass transit facilities), width of interior drives and access points, general interior circulation, separation of pedestrian and vehicular traffic, access to community facilities, demand for and availability of bicycle parking and storage facilities, and arrangement of parking areas that are safe and convenient and, insofar as practicable, do not detract from the use and enjoyment of proposed buildings and structures and the neighboring properties.

Stormwater Drainage — Special attention shall be given to proper site surface drainage so that removal of surface waters will not adversely affect neighboring properties or the public storm drainage system. Storm water shall be removed from all roofs, canopies and paved areas and carried away in an underground drainage system. Surface water in all paved areas shall be collected at intervals so that it will not obstruct the flow of vehicular or pedestrian traffic, and will not create puddles in the paved areas. See By-Laws of the Town of Brookline-ARTICLE 8.25 Stormwater Management.

Utility Service — Electric, telephone, cable TV and other such lines and equipment shall be underground from the source in the public way to all buildings on the site. The location and screening of transformers and dumpsters shall be indicated on the site plan. The proposed method of sanitary sewage disposal and solid waste disposal shall be indicated.

Advertising Features — The size, location, design, color, texture, lighting and materials of all permanent signs and outdoor advertising structures or features shall not detract from the use and enjoyment of proposed buildings and structures and the surrounding properties.

Special Features — Exposed storage areas, exposed machinery installations, service areas, truck loading areas, utility buildings and structures, and similar accessory areas and structures whether on the building or on the ground, shall be subject to such setbacks, screen plantings or other screening methods as shall reasonably be required to prevent their being incongruous with the existing or contemplated environment and the surrounding properties.

Safety and Security — With respect to personal safety, all open and enclosed spaces shall be designed to facilitate building evacuation and maximize accessibility by fire, police, and other emergency personnel and equipment. Insofar as practicable, all exterior spaces and interior public and semi-public spaces be so designed as to minimize the fear and probability of personal harm or injury by increasing the potential surveillance by neighboring residents and passersby of any accident or attempted criminal act.

Heritage — With respect to Brookline's heritage, removal or disruption of historic, traditional or significant uses, structures, or architectural elements shall be minimized insofar as practicable, whether these exist on the site or on adjacent properties.

Microclimate — With respect to the localized climatic characteristics of a given area, any development which proposes new structures, new hard-surface ground coverage, or the installation of machinery which emits heat, vapor, or fumes, shall endeavor to minimize, insofar as practicable, any adverse impact on light, air, and water resources, or on noise and temperature levels of the immediate environment. The development shall comply with the provisions of the Noise Control By-law.

Energy Efficiency — To the maximum extent possible, proposals shall utilize energy-efficient technology and renewable energy resources and shall adhere to the principles of energy-conscious design with regard to orientation, building materials, shading, landscaping, and other elements. Efforts shall be made to harmonize energy-related components with the character of the building and its surroundings and to prevent adverse effects on the energy consumption of neighboring structures and on the environment.

Specific Standards for Beacon Street And Coolidge Corner General Business District

A front setback may be required greater than would be required under § 5.54, paragraph 2., if deemed necessary to preserve the line of existing facades where this is essential to the purposes of this section.

Where preservation of the existing roof or cornice line of adjoining buildings is considered necessary to the preservation of the desirable visual quality and property values of a particular part of Beacon Street, or the G-1.75(CC) District, conformance with that roof or cornice lines may be required; or, in the case of new buildings permitted to be taller than such adjoining buildings, a setback of the building may be required at the level of the adjoining roof or cornice line.

Where the nature of the following design features is considered significant to the preservation or enhancement of the desirable visual quality and property values of a particular part of Beacon Street, or of the G-1.75 (CC) District, any new structure or alteration shall be harmoniously related to nearby pre-existing structures and the street facade in terms of color, texture, materials, scale, height, setbacks, roof and cornice lines, signs, and design elements such as door and window size and location, door and window detailing including materials for sills, lintels, frames, and thresholds, and any other major design elements.

Guidelines — The Planning Board is authorized to adopt additional guidelines for specific areas of the Town, subject to public notice, hearing and review by the Planning Board. These guidelines amplify the standards outlined in subparagraphs a. through l. above. The goal of these guidelines is to promote building design which is compatible with the character of the Town and its neighborhoods and to avoid negative impacts on these neighborhoods. The guidelines shall be used by the reviewing authority in considering proposals. Strict adherence to the guidelines shall be important in all new development projects but will be especially important where an applicant seeks to take advantage of higher floor area or building height than allowed in § 5.00 by providing public benefits under the provisions of § 5.21 and § 5.32. The guidelines include, but are not limited to, consideration of the following concerns: building massing and setbacks which may in certain cases be more restrictive than those otherwise specified in this By-law; provision of screening and maintenance of screening between non-residential and residential properties; design and location of parking areas and structures; provision of site vehicular access; provision of streetscape improvements including widened sidewalks and streetscape amenities; design character and materials of building facades; and building design and active uses at first floor level facing a public street.

Limited Service Hotel District (Use 8A) — Notwithstanding the other provisions hereof, no special permit shall be required under § 5.09 for a Use 8A - Limited Service Hotel in the G-1.75 (LSH) Limited Service Hotel District which otherwise satisfies the applicable provisions of this By-law. In the G-1.75 (LSH) Limited Service Hotel District, the area of any floor space intended and designed for on-site or off-site parking which is made available for use by the public in a limited service hotel, and any increase in floor area in any existing building resulting from additional parking provided for use by the public in such building or the lot on which such building is located shall not be included in calculating the gross floor area of any building. In addition, in the G-1.75 Limited Service Hotel District, (i) there shall be no minimum rear yard requirement and no minimum setback requirements (either above or below grade) for any structure or facility which provides parking for use by the public and which is otherwise permitted under this By-law, and (ii) access drives for any such structure or facility may be located on an adjoining lot and share a common driveway with such lot. Except to the extent specifically otherwise provided in this By-law, all of the provisions of the By-law applicable to the G-1.75 (CC) Coolidge Corner District (including, without limitation, § 5.06, paragraph 2. shall apply to the G-1.75 (LSH) Limited Service Hotel District.

LOT SIZE, AREA, AND WIDTH REGULATIONS

§ 5.10 MINIMUM LOT SIZE

Where a minimum lot size is specified in Table 5.01 no main building or use shall be erected or established on any lot of lesser size, except as may be permitted by § 5.15.

§ 5.11 CLUSTER SUBDIVISIONS, DESIGNED GROUPS OF SINGLE-FAMILY DWELLINGS, AND ESTATE CONVERSIONS

The minimum lot size for lots in a residential subdivision approved by the Planning Board may be 20,000 square feet in an S-40 District, 12,500 square feet in an S-25 District and 7,500 square feet in an S-15 District, provided that the following conditions are met:

the subdivision is 5 acres or more in total area in S-40 Districts, 3 acres or more in S-25 Districts, and 2 acres or more in S-15 Districts, including public or private ways, platted lots, and the permanent open space specified below;

the total number of lots does not exceed the number that would result if the total area of the subdivision were divided by the minimum lot size for lots in subdivisions not subject to this Section;

land is set aside within the subdivision and its maintenance as permanent open space assured by covenant satisfactory to the Board of Appeals or by some other manner satisfactory to the Board of Appeals, in compliance with M.G.L. Chapter 40A, The Zoning Act, the area of such land to be not less than the difference between the total area platted in the subdivision and the total area which would have been so platted if all lots were of the minimum lot size for lots in normal subdivisions not subject to this Section, as determined by the Planning Board in the review of the subdivisions;

the land so set aside is shown on the approved subdivision plan and provided in such a manner that it is usable for recreation or other activities, and is accessible to all residents of the subdivision or, where the land has been deeded to the Town, to the public.

The Board of Appeals by special permit may authorize the development of designed groups of single-family dwellings in S and SC Districts subject to the following conditions and procedures:

the lot is 5 acres or more in area in S-40 Districts, 3 acres or more in S-25 Districts, 2 acres or more in S-15, S-10 and S-7 Districts; and 1 or more acres in SC-10 and SC-7 Districts. Lot area shall be defined in accordance with, § 2.12, paragraph 6 and contiguous lots may be combined to satisfy the acreage requirements of this paragraph;

except as increased under § 5.11, paragraph 2, subparagraph d., the total number of dwelling units does not exceed the number that would result if the area of the lot were divided by the minimum lot size in the district for single-family detached dwellings (the "base density"). Where the computation of base density results in a fractional number, only the fraction of one-half or more shall be counted as one. The Board of Appeals may limit the total number of dwelling units to less than the base density if in its judgment substantially adverse lot conditions, such as soil, topography, shape, significant landscape features or abutting uses, so require. In determining the lot area for purposes of calculating the allowable number of dwelling units, if any part of the lot is wetland as determined by the Conservation Commission, no more than 10 percent of the area to be used for calculation shall be wetland;

permitted dwellings may be either attached or detached or any combination of the two types;

the Board of Appeals may grant a number of dwelling units higher than permitted in § 5.11, paragraph 2, subparagraph b. where any of the following conditions obtain, provided that the increase shall not exceed 25% in total beyond what is permitted in § 5.11, paragraph 2, subparagraph b.

Open Space — A 1% bonus for every 20% increase in landscaped open space over the minimum amount of landscaped open space required by Table 5.01 and a 1% bonus for every 20% increase in usable open space over the minimum amount of usable open space required by Table 5.01.

Concealed Parking — A 1% bonus per 5% of required parking concealed below grade, within or under a residential structure.

Superior Site Design — Up to 10% bonus for superior site design, which may include, without limitation: public open space, either accessible to the public or within public view; historically appropriate building materials; preservation of existing dwellings or other architecturally significant structures; preservation of significant trees; street improvements such as wider sidewalks, underground wiring, lighting, landscaping, and pedestrian walkways and benches; provision of active and passive recreational facilities that are appropriate to the proposed development and to its immediately surrounding neighborhood; maintenance of Town open space; creation, restoration and preservation of access to existing Town open space; preservation and protection of environmentally sensitive areas; sensitivity to the surrounding neighborhood; support for neighborhood facilities and services; and preservation of historical structures significant to the Town. Any such element of site design which usefully and substantially exceeds the applicable minimum requirement for such element, if any, shall be deemed to contribute to the superiority of such site design.

The entire lot shall be designed to, and shall, remain in one ownership and shall be developed and maintained as a whole, except that:

individual dwelling units together with the immediately adjacent yard areas designed for the private use of the residents of the individual dwelling units may be individually owned by any method deemed by the Board of Appeals to ensure the unified control and maintenance of the entire lot; and

the open space created under this Section shall be owned, preserved and protected as provided in § 5.11, paragraph 2., subparagraph j.

The minimum land area occupied by each detached single-family dwelling together with immediately adjacent yard areas designed for the private use of the occupant family shall not be less than is required in § 5.11, paragraph 1.;

The minimum land area occupied by each attached single-family dwelling together with immediately adjacent yard areas designed for the private use of the occupant family shall be 2,000 square feet, and the minimum width of such land area and of each such dwelling between party walls shall be 25 feet;

The maximum horizontal dimension of any group of attached single-family dwellings together with one-story wings or attached accessory structures shall not exceed 150 feet, and the maximum horizontal dimension of that part of such a group that is more than one-story in height shall not exceed 120 feet;

Each group of attached single-family dwellings shall be separated from the end of any other such group by a distance not less than two times the minimum side yard specified in Table 5.01 for the district in which the site is located; and where two such groups are placed face to face or back to back and are parallel or within 45 degrees of parallel they shall be separated by a distance not less than the sum of the minimum front and rear yards specified for the district in said section;

The open space created under this Section shall be designed, developed and maintained for the use and enjoyment of all residents in common, and shall be restricted by deed or covenant to be used primarily for recreational, park, conservation or other open space uses, and shall be conveyed to the Town and accepted by it for park or open space use, or to a non-profit organization the principal purpose of which is the conservation of open space, or to a corporation or trust owned or to be owned by the owners of the dwelling units. When facilities for the service and maintenance of the open space are located within the open space, their combined gross floor area shall not exceed one half of one percent of the open space area;

No building, parking area, swimming pool, or any area designed and intended for active recreation shall be located nearer to any side or rear lot line than the dimension specified for the minimum rear yard by Table 5.01 for the district in which the site is located and the Board of Appeals may require that such intervening space be so densely landscaped as to provide effective visual screening from adjoining property zoned for residence; except that no detached single-family dwelling need be farther from any lot line than required by the yard regulations applicable in the district;

An application for a special permit for a designed group of single-family dwellings under this Section shall be subject to the Community and Environmental Impact and Design Review procedures and standards of § 5.09;

In granting a special permit for a designed group of single-family dwellings under this Section, in addition to the findings required under § 5.09, and § 9.05 the Board of Appeals shall find that:

the location, topography, vicinity or natural features of the site make it particularly suitable for such development, and

the design of the development is such as to be in harmony with the prevailing character of the neighborhood.

The Board of Appeals may by special permit authorize the conversion of an existing structure or structures in S or SC Districts, constructed prior to the effective date of this By-law (July 27, 1962), to two or more dwelling units provided the following conditions are met:

The lot upon which the existing structure or structures are located is 5 acres or more in S-40 Districts, 3 acres or more in S-25 Districts, 2 acres or more in S-15, S-10 and S-7 Districts, and 1 or more acres in SC-10 and SC-7 Districts. Lot area shall be defined in accordance with § 2.12, paragraph 6., and contiguous lots may be combined to satisfy the acreage requirements of this paragraph;

one or more of the existing structure or structures to be converted contain at least 5,000 square feet of floor area either as defined in § 2.07, paragraph 1. or potentially habitable area that could be converted without any exterior construction that adds floor area;

except as increased under § 5.11, paragraph 3, subparagraph d., the total number of dwelling units does not exceed the number that would result if the area of the lot were divided by the minimum lot size in the district for single-family detached dwellings (the "base density") or, if:

more than 50% of the total number of dwelling units are contained in existing structure or structures; and

more than 50% of the total floor area of the existing structure or structures are preserved, restored, renovated and rehabilitated as dwelling units or ancillary structures; the total number of dwelling units does not exceed 125% of the base density. The number of dwelling units permitted by the Board of Appeals under this § 5.11, paragraph 3., subparagraph c. in excess of the base density shall reflect the historic, architectural and community significance of the existing structure or structures once converted to dwelling units, including, without limitation, their design, location, facades, building materials and compatibility with the predominant architecture of the surrounding neighborhood. The Board of Appeals may limit the total number of dwelling units to less than the base density if in its judgment substantially adverse lot conditions, such as soil, topography, shape, significant landscape features or abutting uses, so require, or if the preservation or restoration of the historical or other architecturally significant features of the building(s) would be prevented or materially impaired.

The Board of Appeals may grant a number of dwelling units higher than permitted in § 5.11, paragraph 3., subparagraph c. where any of the following conditions obtain, provided that the increase shall not exceed 25% in total beyond what is permitted in § 5.11, paragraph 3., subparagraph c.

Effective Conversion of Existing Structures to Residential Use — A 2% bonus per every 10%, in excess of 50%, of a percentage equal to the number of dwelling units contained in the existing structure or structures divided by the total number of proposed dwelling units on the lot.

Concealed Parking — A 1% bonus per 5% of required parking concealed below grade, within or under a residential structure.

The entire lot shall be designed to, and shall, remain in one ownership and shall be developed and maintained as a whole, except that:

the open space created under this Section shall be owned, preserved and protected as provided in § 5.11, paragraph 3., subparagraph f.

The open space created under this Section shall be designed, developed and maintained for the use and enjoyment of all residents in common, shall be restricted by deed or covenant to be used primarily for recreational, park, conservation or other open space uses, and shall be conveyed to the Town and accepted by it for park or open space use, or to a nonprofit organization the principal purpose of which is the conservation of open space, or to a corporation or trust owned or to be owned by the owners of the dwelling units. When facilities for the service and maintenance of the open space are located within the open space, their combined gross floor area shall not exceed one- half of one percent of the open space area.

An application for a special permit for a conversion under this paragraph shall be subject to the Community and Environmental Impact and Design Review procedures and standards of § 5.09;

In granting a special permit under this paragraph, in addition to the findings required under § 5.09 and 9.05, the Board of Appeals shall find that:

the location, topography, vicinity, or natural features of the lot make it particularly suitable for such development, and

the structure(s) on the lot is of an appearance which is compatible with the vicinity or which shall be preserved or restored in a manner to justify granting a special permit under this § 5.11;

In addition to the conditions and safeguards listed in § 9.05, paragraph 2. which the Board of Appeals may attach to a special permit relief, the Board may require facade, open space or other such easements to ensure that the historical and architectural character of the lot and structure(s) is protected.

The Board of Appeals, where appropriate, shall consult with the Planning Board, the Conservation Commission, the Preservation Commission and any other municipal authority, board, commission or other agency when any site condition, element of site design or other aspect of the proposed cluster subdivision, designed group of single-family dwellings or estate conversion falls within the regulatory authority of such municipal agency and bears materially on any discretionary increase or decrease in the total number of dwelling units allowed under any special permit granted under this § 5.11.

A proposal may combine the development alternatives permitted by paragraphs 1. through 3. of this § 5.11 provided that the site satisfies the most restrictive threshold acreage requirement of the subsections under which a special permit is sought. Otherwise, and where applicable, when a majority of the site's proposed dwelling units are to be developed as a subdivision, as a designed group or from the conversion of an existing structure or structures, then the development of the site will be subject to the conditions and standards set out in paragraphs 1., 2., or 3., respectively, of this § 5.11. Regardless of which subsection of § 5.11 governs the development of the site, any new construction shall contain only attached or detached dwellings, but converted existing structures may contain one or more dwelling units in any configuration.

All subdivisions of 10 lots or more seeking special permits or variances for increases in permissible density or intensity of use are also subject to the provisions of § 4.08.

§ 5.12 LOT AREA PER DWELLING UNIT OR EQUIVALENT

Where a minimum lot area per dwelling unit is specified in Table 5.01 the minimum lot area for the first dwelling unit on a lot shall be provided on such lot for each additional dwelling unit as specified in Table 5.01.

§ 5.13 LOT WIDTH

Where a minimum lot width is specified in Table 5.01 no main building shall be erected on any part of a lot which has a width less than is specified in said Section, except as may be permitted by § 5.15, and except that under a special permit the Board of Appeals may permit lot widths less than the minimum specified for one-family attached dwellings.

§ 5.14 LOT FRONTAGE

Every lot shall have a minimum frontage of not less than 25 feet in S and SC Districts, and of not less than 20 feet in other districts, upon a street not less than 40 feet in width; except that the Board of Appeals may grant a special permit for use of a lot which has the required frontage upon a street not less than 30 feet in width, provided such street had been opened or dedicated to public use prior to 1922 or has been approved by the Planning Board as part of a subdivision. Such frontage shall not be obstructed from vehicular access to the street by walls, fences, or other barriers.

Figure 5.03 - Lot Frontage

Where a lot is located to the rear of another lot or lots, it shall have feasible vehicular access to a street over a strip of land not part of any other lot and not less than 25 feet wide in S and SC Districts nor less than 20 feet in other districts. Such land may not be counted as more than 20 percent of the required lot area of such rear lot.

§ 5.15 EXCEPTION TO MINIMUM LOT SIZE & LOT WIDTH REQUIREMENTS

The provisions of §§ 5.10 and 5.13 shall not prevent the construction or alteration of a single-family dwelling:

On a lot that was not, on July 27, 1962, or any subsequent date, contiguous to a lot in the same ownership, provided that it meets the following conditions:

The lot was lawful under zoning and subdivision regulations in effect when the lot was created.

The yard requirements are observed.

The lot is 4,000 square feet or more in area.

On a lot that was, on July 27, 1962, or on some subsequent date, contiguous to another lot in the same ownership, provided the Board of Appeals finds that a replatting into conforming lots is not practicable and issues a special permit subject to the following conditions:

The yard requirements are observed.

The lot size or lot width is not less than three-fourths of the requirement specified in Table 5.01 unless more than half of the frontage on the same side of the same street in the same block is already built up with such lesser lot sizes or lot widths.

FLOOR AREA RATIO REGULATIONS

§ 5.20 FLOOR AREA RATIO

For any building or group of buildings on a lot the ratio of gross floor area to lot area shall not exceed the maximum specified in the Table of Dimensional Requirements.

Figure 5.04 - Computation of Floor Area Ratio

§ 5.21 EXCEPTIONS TO MAXIMUM FLOOR AREA RATIO REGULATIONS (PUBLIC BENEFIT INCENTIVES)

The following public benefits have been determined to be of sufficient importance to the Town to provide eligibility for additional Floor Area Ratio. The Board of Appeals shall find that the size of any bonus granted is commensurate with the public benefit offered. No bonus shall be granted where the claimed public benefit is otherwise required by this Zoning By-Law or by any other by-law, statute, code or regulation.

The Board of Appeals may grant by special permit a maximum gross floor area higher than is permitted in Table 5.01, subject to the procedures, limitations, and conditions specified in this Section, and provided that public benefits including but not limited to the following are provided by the developer of the lot as required by the Board of Appeals: affordable housing, in excess of that required by the Zoning By-Law; landscaped and/or usable open space within public view, in excess of that required by the Zoning By-Law; support, financial or otherwise, for community facilities and services, including maintenance, enhancement, and acquisition of Town parks or open space; environmentally friendly sustainable building and site planning practices, significant provision of public parking and/or parking for car rental sharing services; subsidized MBTA passes for employees; provision of daycare space, either on or off-site; and preservation of historic structures.

Public Benefit Incentives may be granted under this Section only for a lot (or part of a lot) which meets the following basic requirements:

The lot (or part of a lot) is located in a district with a floor area ratio of 1.5 or greater.

The lot (or part of a lot) is not less than 20,000 square feet.

No lot (or part of a lot) within a buffer area, as defined in § 5.31, paragraph 3., shall be eligible for any provision or counted toward any requirement of this Section for gross floor area in excess of that permitted in Table 5.01, nor shall such bonus floor area be located thereon.

No driveway from the lot shall enter a street opposite from an S, SC, or T district.

To aid the Board of Appeals in making the findings required in § 9.05 and the Planning Board in preparing the advisory report provided for in § 9.04, the applicant shall submit the materials required by § 5.09, paragraph 3. in addition to the usual drawings at the time of application.

The additional gross floor area granted in accordance with this Section, as calculated by the following percentage, shall not exceed the maximum floor area ratio specified in the Public Benefit Incentives column of Table 5.01:

Table 5.02 - Table of Maximum Gross Floor Area Increase

Each Condition	M-2.5 Districts	M-1.5, M-2.0, G-1.75(CC), G-2.0, GMR-2.0 & O-2.0(CH) Districts
Affordable Housing	30%	20%
Landscaped and/or Usable Open Space	20%	15%
Community Facilities and Services Support	20%	15%
Preservation of Historic Structures	20%	15%

The Board of Appeals may grant additional gross floor area where any of the following conditions obtain, subject to the limitations in paragraph 4. above. The additional gross floor area shall be calculated separately for each condition based upon the gross floor area permitted in Table 5.01.

Affordable Housing

Where on site affordable units, defined as dwelling units subject to restrictions on the income of occupants and on maximum rents or sales prices in order to conform with federal, state or local legislation or regulations, including Section 4.08 of the Zoning By-Law, are provided in excess of the requirement in the zoning by-law, such gross floor area attributable to such affordable units may be allowed up to the bonus percentage listed in Table 5.02 above but the total FAR shall not exceed the maximum floor area ratio specified in the Public Benefit Incentives column of Table 5.01.

Landscaped or Usable Open Space

Where public landscaped open space or usable open space within public view is provided in excess of the minimum specified in Table 5.01, additional gross floor area may be allowed at the rate of two square feet of gross floor area for each one square foot of either kind of open space in excess of the minimum requirements, up to the bonus percentage listed in Table 5.02 above but the total FAR shall not exceed the maximum floor area ratio specified in the Public Benefit Incentives column of Table 5.01.

Community Services and Facilities Support

Where support, financial or otherwise, for community services and/or facilities is provided, such as maintenance, enhancement, and acquisition of Town parks or open space, environmentally friendly sustainable building and site planning practices, significant provision of public parking and/or parking for car rental sharing services; subsidized MBTA passes for employees; provision of daycare space, either on or offsite, the allowed gross floor area in Table 5.01 may be exceeded up to the bonus percentage listed in Table 5.02 above but the total FAR shall not exceed the maximum floor area ratio specified in the Public Benefit Incentives column of Table 5.01.

Preservation of Historic Structures

Where preservation of historic structures, not otherwise required by the zoning by-law, is undertaken, the gross floor area in Table 5.01 may be exceeded up to the bonus percentage listed in Table 5.02 above, but the total FAR shall not exceed the maximum floor area ratio specified in the Public Benefit Incentives column of Table 5.01. In any such case, the Board of Appeals shall, prior to allowing additional gross floor area, consult with the Preservation Commission in connection with determining whether the structure in question is historic, and the Preservation Commission shall advise the Board of Appeals in connection with the design review of changes affecting the structure in question.

§ 5.22 EXCEPTIONS TO MAXIMUM FLOOR AREA RATIO (FAR) REGULATIONS FOR RESIDENTIAL UNITS

General Provisions

Any expanded unit (individual residential units subject to an increase in gross floor area as per this Section) shall not be eligible to be subsequently divided into multiple units. If the limitations set forth in this paragraph 1, subparagraph a, or the limitations in paragraph 2 regarding separate dwelling units, should be found to be invalid, § 5.22 shall be deemed null and void in its entirety, and no increase in gross floor area shall be allowed pursuant to § 5.22, except for accessory dwelling units per Section 4.05(2).

Insofar as practicable, the additional floor area allowed pursuant to this Section shall be located and designed so as to minimize the adverse impact on abutting properties and ways, and interior conversions shall be considered preferable to exterior additions. Any exterior additions or modifications shall further comply with the provisions of § 5.09, including § 5.09.4.c, §§ 9.03 to 9.05, and this Section. The limitations and standards set forth in such provisions shall also guide the Zoning Board of Appeals in determining under G.L. c.40A, § 6 whether a change, extension or alteration is substantially more detrimental to the neighborhood than an existing nonconforming use.

Additional floor area shall be allowed pursuant to this Section only if the Certificate of Occupancy for the original construction was granted at least ten years prior to the date of the application for additional gross floor area under this section or if there is other evidence of lawful occupancy at least ten years prior to the date of such application. In the case of the substantial demolition of a structure or of an increase in the number of units, the time period prior to such demolition or unit increase shall not be counted toward the required ten-year waiting period, and the ten-year waiting period shall be deemed to commence with the grant of a new Certificate of Occupancy after such demolition or unit increase. As used in this paragraph 1, subparagraph c, "substantial demolition" shall mean the act of pulling down, destroying, removing or razing a structure or a significant portion thereof, by removing one or more sides of the structure, or removing the roof, or removing 25% or more of the structure. If the limitation set forth in this paragraph 1, subparagraph c should be found to be invalid, § 5.22 shall be deemed null and void in its entirety, and no increase in gross floor area shall be allowed pursuant to § 5.22.

Exterior modifications to accommodate an exterior addition or interior conversion shall include without limitation the addition of a dormer, penthouse, cupola, windows, doors or the like. Such modifications shall also not conflict with any other provisions of the Zoning By-law. Interior conversion and exterior addition are terms defined in § 2.09. An exterior modification such as a dormer or penthouse which is usable for human occupancy shall be deemed an exterior addition.

The interior conversion shall not result in the displacement of interior storage of equipment, vehicles, or materials to a location which is now exterior to the house.

In determining the appropriate amount of space to be converted into habitable space, the Board of Appeals shall consider the extent of exterior modifications required to effectuate the proposed conversion and/or exterior addition and the impact thereof on abutting properties.

Space that has previously been decommissioned shall not be converted under this Section.

Under paragraph 3 below, the Board of Appeals may allow for the conversion of attic or basement space not meeting the requirements of paragraph 2, for conversions of interior space other than attic or basement space, and for exterior additions.

Conversion of Attic or Basement Space in Single-Family and Two-Family Residential Dwellings

Conversions of attics or basements to habitable space for use as part of an existing single- or two-family dwelling, not as a separate dwelling unit, and effectively increasing the gross floor area of the dwelling, shall be allowed in S and SC districts provided the following conditions are met in addition to the conditions set forth in paragraph 1 of this Section:

Any exterior modifications that are made to the structure to accommodate the conversion shall be subject to the procedures, limitations, and conditions specified in § 5.09, §§ 9.03 to 9.05, and this Section. No exterior modifications made under the provisions of this subparagraph may project above the ridge of the roof nor project beyond the eaves.

Any increase in gross floor area through such basement or attic conversion shall be limited such that the total resulting gross floor area of the building(s) after such conversion is no more than 130% of the total permitted in Table 5.01 (the "permitted gross floor area"). For purposes of this subsection only, an accessory dwelling unit, as per Section 4.05 paragraph 2 shall not be considered a separate unit.

Special Permit for Exceeding Maximum Gross Floor Area for Residential Dwellings

The Board of Appeals may allow, by special permit, a maximum gross floor area greater than permitted gross floor area for an existing residential building(s) on a single lot, subject to the procedures, limitations, and conditions specified in § 5.09, §§ 9.03 to 9.05, and this Section for an existing residential building which meets the following basic requirements:

The existing building(s) is located on a lot (or part of a lot) in an S or SC district.

The existing building contains at least one residential unit but no more than two total units. For the purpose of this paragraph 3, subparagraph (a)(2), total units shall be defined to include all residential dwellings, offices, and commercial spaces within the building.

The additional floor area allowed by special permit pursuant to this Section shall not include the floor area permitted by right under Table 5.01.

The maximum increase in floor area allowed by special permit may be allowed only in accordance with the following conditions, which shall be in addition to the other conditions set forth in this Section, including paragraph 1, and any other conditions that the Board of Appeals may prescribe. In no case shall the resulting total gross floor area of the building(s) after all conversions and additions be more than 130% of the permitted gross floor area:

In all S and SC Districts, a special permit may be granted for an increase in floor area above the permitted gross floor area for only one of the following subparagraphs (such that the grant of a special permit under one subparagraph shall preclude the subsequent grant of a special permit under a different subparagraph, but shall not, to the extent the increase in floor area allowable under one subparagraph has not been fully utilized, preclude a subsequent grant of an additional special permit under that same subparagraph so as to fully utilize the increase in floor area allowable under that subparagraph. Notwithstanding the foregoing, an applicant who has received a special permit under subparagraph (a) or (b) and has not fully utilized the allowable increase in floor area under that subparagraph may apply for a special permit under subparagraph (c), with the increased floor area previously allowed under subparagraph (a) or (b) counted against the floor area allowable under subparagraph (c)):

An interior conversion that is less than or equal to 30% of the permitted gross floor area;

An exterior addition that is less than or equal to 20% of the permitted gross floor area; or

A combination of an interior conversion and exterior addition that is less than or equal to 30% of the permitted gross floor area, provided that the additional floor area attributable to exterior construction (which shall include the floor area included within dormers, penthouses, cupolas, and the like) does not exceed 35% of the additional floor area allowed by special permit.

The grant of a special permit under any prior version of Section 5.22 shall be deemed the grant of a special permit under this section.

If the application of the percentages in paragraph 3, subparagraph b results in a floor area increase of less than 350 square feet, a special permit may be granted for an increase in floor area of up to 350 square feet provided that the resulting gross floor area of the building(s) is not more than 150% of the permitted gross floor area. The prior grant of additional gross floor area as of right or by special permit under Section 5.22 or any prior version of Section 5.22 shall preclude a subsequent grant of a special permit under this paragraph 3, subparagraph c.

HEIGHT OF BUILDING REGULATIONS

§ 5.30 MAXIMUM HEIGHT OF BUILDINGS

Where a maximum height of buildings is specified in Table 5.01 no building or part of a building shall exceed the number of feet in height, except as permitted in §§ 5.31 and 5.32. Height shall be measured as follows:

Where the lot abuts other lots to the rear which are subject to the same or less restrictive height limitations:

Height shall be measured from the record grade of the street opposite the midpoint of the street frontage of the lot, or, if a corner lot, of the street frontage having the lower record grade.

Where the grade of the natural ground contiguous to the building is higher than said record grade, height may be measured from the mean grade of said natural grade, except if said mean grade is higher than the mean natural grade of any abutting lot at the lot line.

Where the mean grade of the natural ground contiguous to the building is higher than both the record grade of the street and the mean natural grade of any abutting lot at the lot line, height shall be measured from a level not exceeding the mean grade of the lowest of any lot by more than one-fourth of the distance between the building and said abutting lot line.

Figure 5.05 - Measurement of Building Height When the Rear Abutting Lot is Subject to Same or Less Restrictive Height Limitation

Where the lot abuts other lots to the rear which are subject to more restrictive height limitations:

For a building or buildings on a lot not more than 160 feet in any dimension:

Height shall be measured from the record grade of the street opposite the midpoint of the street frontage of the lot, or, if a corner lot, of the street frontage having the lower record grade.

Figure 5.06 - Height Measurement For a Lot Not More Than 160 Feet in Any Dimension

For a building or buildings on a lot whose depth is not more than 160 feet but whose frontage is greater than 160 feet:

For that part of the lot within 80 feet of each side lot line not also a street line, height shall be measured from the record grade of the street at a point 40 feet from the side lot line.

For that part of the lot within 80 feet of a side lot line, which is also a street line, height shall be measured from the record grade of the side street at a point opposite the midpoint of the side street lot line.

For that part of the lot more than 80 feet from a side lot line, height shall be measured from the record grade of the street opposite the midpoint of that part of the lot.

Figure 5.07 - Height Measurement For a Lot Not More Than 160 Feet in Depth

For a building or buildings on a lot whose depth and frontage both exceed 160 feet, height shall be measured as provided in subparagraph b. hereof with the following exceptions:

If the grade of the natural ground contiguous to the building is not more than 10 feet higher than the record grade of the street, height may be measured from the mean grade of said natural ground.

If the grade of the natural ground contiguous to the building is more than 10 feet higher than the record grade of the street, height may be measured from a level 10 feet above said record grade.

Figure 5.08 - Height Measurement For a Lot More Than 160 Feet in Both Depth and Frontage

For a building or buildings on a lot whose frontage is not more than 160 feet but whose depth is greater than 160 feet:

Height shall be measured from the record grade of the street opposite the midpoint of the street frontage of the lot, or, if a corner lot, of the street frontage having the lower record grade.

If the grade of the natural ground contiguous to the building is not more than 10 feet higher than the record grade of the street, height may be measured from the mean grade of said natural ground.

If the grade of the natural ground contiguous to the building is more than 10 feet higher than the record grade of the street, height may be measured from a level 10 feet above said record grade.

Where the lot fronts on two streets, maximum height shall be calculated as provided in paragraphs 1. and 2. of this Section, whichever is appropriate, interpreting "lots to the rear" as lots across the street. In such cases, a line shall be drawn halfway between the two streets which the lot adjoins, maximum height shall be measured from the record grade of each street separately, and the maximum height so measured shall apply on each side to that portion of the lot which lies between the line and each street. Maximum height for corner lots shall be calculated as provided in paragraphs 1. and 2. of this Section.

§ 5.31 EXCEPTIONS TO MAXIMUM HEIGHT REGULATIONS

The provisions of § 5.30 shall not apply to church spires, belfries, cupolas, domes, monuments, water towers, observation towers, transmission towers, windmills, chimneys, smokestacks, silos, derricks, conveyors, flag poles, masts, aerials, elevator penthouses, water tanks, monitors, or other structures normally built above the roof and not devoted to human occupancy. Such structures, however, shall be erected only to such heights and of such areas as are necessary to accomplish the purpose they are normally intended to serve, and shall harmonize with the facade of the building. Any structure designed for mechanical or electrical use shall be concealed or screened from public view to the greatest extent feasible and shall comply with the provisions of the Noise Control By-law. Substantial rooftop structures such as observation towers, elevator penthouses and mechanical equipment shall not exceed the height limit by more than 10 feet unless a special permit is granted by the Board of Appeals.

In a situation where the interpretation of the requirements of § 5.30 is not clear as a result of non-typical lot shape, topography, building alignment or configuration, or other characteristic, the Board of Appeals under a special permit after a hearing may establish maximum heights for a building or buildings or for different parts of a building which it deems will best approximate the requirements of § 5.30 and will assure the same standard of amenity to nearby properties as would have been provided by the application of said requirements to the site in question in the absence of non-typical characteristics.

Where two different maximum height figures are specified for the same zoning district in Table 5.01, the lower figure shall apply to any lot or part of a lot located in a buffer area. A buffer area is defined as a lot or part of a lot located in an M-1.5, M-2.0, M-2.5, G-1.75(CC), G-2.0 or O-2.0(CH) District which is located at a lesser distance from any land not within a public way in an S, SC, T or F District than the following:

200 feet if the direction of the land in the S, SC, T or F District is northerly, between northwest and northeast;

150 feet if such direction is easterly, between northeast and southeast, or westerly, between northwest and southwest;

100 feet if such direction is southerly, between southeast and southwest.

§ 5.32 EXCEPTIONS TO MAXIMUM HEIGHT REGULATIONS (PUBLIC BENEFIT INCENTIVES)

Special Permit Required

The Board of Appeals may allow by special permit a maximum height greater than is permitted in Table 5.01 in M-1.5, M-2.0, GMR-2.0, M-2.5, G-1.75(CC), G-2.0 and O-2.0(CH) Districts, provided the maximum height allowed does not exceed the maximum heights specified in the Public Benefit Incentives column of Table 5.01, and provided that all of the conditions of paragraph 2. of this Section are satisfied.

Public Benefits and Conditions

As required by the Board of Appeals, the developer of the lot shall provide substantial public benefits including but not limited to public parking; public open space, either within public view or access; historically appropriate building materials; street improvements such as paving, wider sidewalks, underground wiring, lighting, landscaping, and pedestrian walkways and benches; maintenance of Town open spaces; and preservation of historic structures significant to the Town. The Board of Appeals shall find that the amount of any additional height allowed is commensurate with the public benefit offered. No additional height shall be allowed where the claimed public benefit is otherwise required by this Zoning By-Law or by any other by-law, statute, code or regulation.

Any additional height allowed by the provisions of this Section, above that permitted by right, shall be set back from street lot lines as follows:

In M-1.5, M-2.0, M-2.5, G-1.75, and O-2.0(CH) Districts, the setback requirement from any street lot line on which the lot fronts shall be one-half of the width of the street right-of-way, up to a maximum requirement of 50 feet.

In G-2.0 Districts, for lots which have frontage on Harvard, Cypress, Walnut or Dummer Street, the setback requirement in (i) above shall apply only to the portions of the lots which front on these streets.

Any additional height allowed under the provisions of this Section shall be set back 50 feet from any surrounding land not in a public way in an S, SC, T, F, or M District.

Applications in the G-1.75(CC) District shall be subject to the conditions of § 5.06, paragraph 2.

Any such special permit issued on or after June 7, 1966, shall not be impaired by a modification of the boundaries of zoning districts under § 3.02 within a period of three years subsequent to the date of issuance of such special permit. In addition to the usual conditions which the Board of Appeals may attach in approving a special permit as specified in § 9.05, the Board may require buildings to be located on the south side of the property so as to reduce the effect of shadows on abutting property.

GENERAL YARD AND SETBACK REGULATIONS

§ 5.40 WALLS NOT PARALLEL TO LOT LINES

Where a wall of a building is not parallel with its corresponding lot line, the average width or depth of any yard or setback shall not be less than the dimension specified in Table 5.01 for the required width or depth, provided that said yard or setback shall not be narrower at any point than three-fourths of the required width or depth. In no case in an M District shall a required front yard or side yard adjacent to a street be less than the front yard dimension specified in Table 5.01.

Figure 5.10 - Calculation of Yard and Setback

§ 5.43 EXCEPTIONS TO YARD AND SETBACK REGULATIONS

Under a special permit after a hearing the Board of Appeals may permit, in lieu of the requirements for yards or setbacks specified in this By-law, the substitution of such other dimensional requirements as shall assure the same standard of amenity to nearby properties as would have been provided by compliance with the regulations of the By-law, as measured by off-setting a reduction in the depth or area of a required yard or setback by an increase in the depth or area of another yard or setback or by the provision or preservation of a condition or a facility not otherwise required that will counterbalance such a reduction; provided, however, that under this section the Board of Appeals shall not:

reduce the depth of a required front yard below 15 feet in M Districts; nor

increase the maximum Building Depth, as defined in Sec. 5.93, in T-5(NH) Districts.

§ 5.44 ACCESSORY UNDERGROUND STRUCTURES

Any accessory structure or any part of a main structure or building which is located entirely beneath the surface of the ground at the natural grade level may extend into a required yard, except that in any Residence District and in any other situation where Landscaped Open Space is required, no underground structure or building shall be located beneath more than fifty percent of the required Landscaped Open Space nor nearer than ten feet to any lot line.

Any part of a required side or rear yard may be occupied by an accessory underground garage structure or part of a main building for accessory garage use which is not located entirely beneath the surface of the ground at the natural grade level provided:

The height of any such structure shall not exceed at any point along its wall or walls the grade of the natural ground contiguous to the structure by more than three feet.

There shall be no fence or parapet higher than six feet above such grade of natural ground.

In any situation where Landscaped Open Space is required, such structure shall not be located beneath more than fifty per cent of the required Landscaped Open Space.

Such structure shall be set back from any lot line at least twenty feet in all S Districts, at least ten feet in all other Residence Districts or in any other situation where Landscaped Open Space is required, and at least five feet in all other districts where a side or rear yard setback is required.

The Board of Appeals may by special permit authorize such an accessory underground garage structure or part of a main building which is not located entirely beneath the surface of the ground at the natural grade level within a required front yard provided:

The structure shall meet all the conditions of paragraph 2. of this section.

There shall be no parking on the roof of such structure.

No parked vehicles shall be seen from the street.

The Board of Appeals may by special permit modify the setback requirements in paragraphs 1., 2., and 3. above and the height limitations in subparagraphs a. and b. of paragraph 2. above subject to the provisions of § 9.06 and provided that such modification is counterbalanced by appropriate landscaping and screening to assure the same standard of amenity to nearby properties as would have been provided by compliance with the regulations of the By-law.

§ 5.45 TRAFFIC VISIBILITY ACROSS CORNERS

In any district where a front yard is required, no structure, fence, planting or other structure shall be maintained between a plane two and one-half feet above curb level and a plane seven feet above curb level so as to interfere with traffic visibility across the corner within that part of the lot which is within a triangle bounded by the street lot lines and, a straight line drawn between points on each such lot line 25 feet from the intersection of said lot lines or extension thereof, except if the Director of Transportation determines that no safety hazard will result, such as from a fence or plantings that allows adequate visibility.

Figure 5.11 — Traffic Visibility Across Corners

§ 5.46 CORNER LOTS

For a corner lot, the required yard along any street lot line shall be calculated as a front yard, except that in S, SC, T and F Districts where the rear lot line of a corner lot is also the rear lot line of the contiguous lot, the required front yard extending from the rear yard to the corner shall be 20 percent of the width of the lot measured along the other front yard line, but need not be greater than the required front yard depth and shall not be less than the required width of a side yard calculated as if the street lot line were an interior side lot line.

§ 5.47 DIMENSIONAL REQUIREMENTS FOR COURTS

Where a court opens out to a yard or lot line, and where the minimum required yard is specified in terms of a formula, any wall of the building bounding the court parallel or within 45° of parallel with the lot line shall be set back from that lot line in accordance with the provisions of § 5.41 paragraphs 1. or 2.

Where a court is enclosed by apartment wings, any one of which contains all the rooms of one or more dwelling units, a distance equal to twice the required side yard as specified in Table 5.01 shall be provided between the wings.

Projections, accessory buildings and structures in courts shall be controlled by the regulations for yards applicable to the yard or lot line upon which the court opens or, in the case of apartment wings, the regulations applicable to side yards.

FRONT YARD REGULATIONS

§ 5.50 FRONT YARD REQUIREMENTS

Where a minimum depth of front yard is specified in Table 5.01, an open space of at least the specified depth shall be provided between the front lot line or lines and the nearest point of any building or structure except as may be permitted hereafter. (See illustrations in § 5.40)

§ 5.51 PROJECTIONS INTO FRONT YARDS

Bays and porches not over half the length of the front wall may project into any front yard three and one-half feet. Belt courses, chimneys, flues, fins, columns, leaders, sills, pilasters, lintels and ornamental features may project not more than one foot, and cornices and gutters not more than two feet, over a required front yard. In no case shall any such projection come within five feet of any front lot line, except in districts where no front yard is required.

§ 5.52 FENCES AND TERRACES IN FRONT YARDS

Subject to § 5.45, the provisions of § 5.50 shall not apply to front fences, hedges, or walls not over six feet high above the natural grade in the required front yard nor to terraces, steps, uncovered porches, or other similar features not over three feet high above the level of the floor of the ground story. Piers, pilasters, columns, and posts not over sixteen inches square as supports may exceed the height limitation by not more than twelve inches. Uncovered porches or decks may not extend into the yard more than fifty per cent of the required yard setback but in no case closer than six feet to the property line.

§ 5.53 ACCESSORY BUILDINGS IN FRONT YARDS

Accessory buildings shall not be permitted within required front yards.

§ 5.54 EXCEPTIONS FOR EXISTING ALIGNMENT

In L, G, O or I Districts, if the alignment of existing buildings on adjacent lots on both sides of a lot fronting on the same street is nearer to the street than the required front yard depth, the average of the existing alignment of all buildings within 150 feet of said lot shall be the required front yard.

Figure 5.12 - Exception for Existing Alignment

In all Residence Districts, if the alignment of two or more existing buildings on lots on either or both sides of a lot fronting on the same side of the same street in the same block is farther from the street than the required front yard depth, the average of the existing alignment of all buildings within 150 feet of said lot shall be the required front yard, except that no front yard requirement resulting from the application of this section shall exceed twice the front yard requirement specified in Table 5.01.

Figure 5.13 - Exception for Existing Alignment

The average of the existing alignment as used in paragraphs 1. and 2. of this section shall be calculated as follows:

Multiply the actual front yard depth of each part of each existing building by the frontage of that part of the building measured parallel to the street, and

Add the products thus calculated and divide the sum by the total of the frontage of all existing buildings.

In any district, where a row of two or more existing attached buildings in different ownership has a deeper front yard than that required by Table 5.01 of this By-law, construction of any building or structure in the area between any one of said buildings and its required front yard line shall require a special permit from the Board of Appeals.

§ 5.55 FRONT YARD FOR REAR LOT

Where a dwelling is to be located on a rear lot, the front yard depth shall be not less than the minimum rear yard specified in Table 5.01. A lot shall be considered to be a rear lot if a straight line drawn from any part of the proposed building, to and perpendicular to the street providing required access to the lot, passes through any part of a conforming main building, or site thereof, on another lot.

Figure 5.14 - Front Yard for Rear Lot

SIDE YARD REGULATIONS

§ 5.60 SIDE YARD REQUIREMENTS
