Montgomery County Unincorporated
City Zoning Code

ARTICLE 59

8. Zones Retained From Previous Ordinance

Section 8.1.1. Applicability

The zones in Article 59-8, Sections 8.1 through 8.3, were applied by Local Map Amendment before this Zoning Ordinance was adopted. These zones may appear on the digital zoning map, but they cannot be requested by any property owner under a Local Map Amendment or confirmed or applied to any property under a Sectional Map Amendment adopted after October 30, 2014. Section 8.4, Optional Method Public Benefits, is the Public Benefit system in effect prior to January 1 2026 for optional method development projects in the Commercial/Residential and Employment zones.
(Legislative History: Ord. No. 18-08, § 31; Ord. No. 20-21, § 7.)

Section 8.1.2. Modification of Zones

A.   Amending a Development Plan
An amendment to an approved development plan or schematic development plan in any zone in Article 59-8 must follow:
1.   the procedures for amendment of a development plan under the zoning ordinance in effect on October 29, 2014;
2.   the parking, queuing, and loading standards in Division 6.2; and
3.   the signage standards in Division 6.7.
Division 7.7 does not apply to the zones in Article 59-8.
B.   Requesting a New Floating Zone
Unless prohibited by a specific provision of the zone, a property owner of land under any zone in Article 59-8 may request a new Floating zone under Article 59-5.
(Legislative History: Ord. No. 18-08, § 31.)

Section 8.2.1. Zones Established

The residential floating zones under Article 59-8 and their identifying symbols are:
A.   Residential Townhouse -6.0 (RT-6.0),
B.   Residential Townhouse- 8.0 (RT-8.0),
C.   Residential Townhouse- 10.0 (RT-10.0),
D.   Residential Townhouse- 12.5 (RT- 12.5),
E.   Residential Townhouse- 15.0 (RT-15.0), and
F.   Multiple-Unit, high-rise planned residential (R-H).

Section 8.2.2. Purpose and Intent

A.   RT Zone
1.   The RT zones provide suitable sites for townhouses in sections of the County:
a.   that are appropriate for residential development at densities allowed in the RT zones; or
b.   where a buffer or transitional use is needed between commercial, industrial, or high-density Multi-Unit Living uses and low-density Single- Unit Living uses.
2.   The RT zones should:
a.   provide maximum freedom in the design of townhouses, including grouping and layout within the areas classified in that zone;
b.   provide the amenities normally associated with less dense zoning categories;
c.   permit different types of ownership of townhouses and townhouse developments;
d.   prevent detrimental effects on adjacent properties or the neighborhood; and
e.   promote the health, safety, and welfare of the current and future inhabitants of the district and the County.
B.   R-H Zone
1.   The R-H zone should:
a.   provide suitable sites for relatively high density residential development;
b.   create economies in the construction and operation of public services such as transportation, retail shopping facilities, and other community facilities that depend upon convenient access by residents of the area;
c.   prevent undue congestion in sections of the County where such public services are not currently available or cannot be conveniently and economically provided;
d.   provide maximum freedom in the design of residential structures, including grouping and layout within the areas classified in that zone;
e.   prevent detrimental effects on adjacent properties or the general neighborhood; and
f.   promote the health, safety, and welfare of the current and future inhabitants of the district and the County.
2.   A development in the R-H zone must provide the maximum possible light, air, and open space for the benefit of the residents and the surrounding area.

Section 8.2.3. Use Table for the RT and R-H Zones

A.   Section 3.1.1 through Section 3.1.4 apply to the Use Table in Section 8.2.3.
B.   The following Use Table identifies uses allowed in each zone. Uses may be modified in Overlay zones under Division 4.9.

C.   R-H Zone Special Regulations for a Development with MPDUs
A development in the R-H zone may use the following optional standards to achieve MPDUs, including any bonus density under Chapter 25A:
1.   The green area may be reduced to a minimum of 35%, if required to accommodate the construction of all workforce housing units on-site.
2.   The requirements for setbacks and distances between apartment buildings may be reduced if an applicant can demonstrate during site plan review that such reductions are necessary to accommodate the increased density.
(Legislative History: Ord. No. 18-08, § 32.)

Section 8.3.1. Zones Established

The planned unit development zones and their identifying symbols are:
A.   Planned Development (PD),
B.   Town Sector (T-S),
C.   Planned Neighborhood (PNZ),
D.   Planned Retirement Community (PRC), and
E.   Planned Cultural Center (PCC).

Section 8.3.2. PD Zone

A.   Purpose
1.   The PD zone should implement the general plan for the Maryland-Washington Regional District and the area master plans by permitting unified development consistent with densities proposed by master plans. This zone provides a flexibility of design that better integrates mutually compatible uses and optimum land planning with greater efficiency, convenience and amenity than conventional zoning categories. The PD zone should be used to implement the general plan, area master plans, and other pertinent county policies in a manner and to a degree that is more compatible with these county plans and policies than under other zoning categories.
2.   A development in the PD zone should be designed and constructed to encourage social and community interaction and activity among those who live and work within an area and to encourage the creation of a distinctive visual character and identity for each development. A development in this zone should have a balanced and coordinated mixture of residential and convenience commercial uses, other commercial and industrial uses shown on the area master plan, and related public and private facilities.
3.   This zone should also:
a.   encourage a broad range of housing types, including owner and rental occupancy units, one-family, multiple-family, and other structural types;
b.   preserve trees by minimizing the amount of grading necessary for construction of a development;
c.   encourage open space:
i.   for use as setbacks and yards surrounding structures and related walkways;
ii.   for use as places for relaxation, recreation, and social activity for the general benefit of the community and the public conveniently located near residential and commercial concentration;
iii.   as part of the plan and design of each development to achieve the physical and aesthetic integration of the uses and activities within each development;
d.   encourage and provide for the development of comprehensive pedestrian circulation networks, separated from vehicular roadways, which link residential areas, open spaces, recreational areas, commercial and employment areas, and public facilities, and thereby minimize reliance upon the automobile; and
e.   encourage developments on a large area of land with a large number of dwelling units that offer opportunities for a wider range of related residential and nonresidential uses.
4.   A development in the PD zone should also maximize the safety, convenience, and amenities for both the residents of the development and the residents of neighboring areas while remaining compatible with existing and proposed surrounding land uses.
B.   Uses
1.   Residential Uses
a.   All types of Residential Uses, including Accessory Residential Uses, listed in Section 3.1.6 are allowed. All Group Living uses must be shown on the Development Plan. Residential Care Facilities (Over 16 persons) are subject to the standards in Section 3.3.2.E.2.c.ii and conditional use approval by the Hearing Examiner under Section 7.3.1.
b.   The various dwelling unit types must be planned and constructed according to the following table. The table establishes, by density category and size of development, the minimum percentage required for each dwelling unit type within a planned development. All remaining dwelling units not included in the minimum requirements may be of any type or combination of types permitted in the applicable density category and development size, provided the maximum percentage is not exceeded in any instance.

Key: NP = Not permitted P = Permitted but not required ( ) = Maximum percentage permitted.
1   County Council may waive the percentage requirements for detached houses and apartment units, if it finds that a proposed development (a) is more desirable for stated environmental reasons than development under these limits, or (b) achieves goals, policies, or recommendations stated in a master or sector plan.
2   If the minimum percentage would yield fewer than 150 apartment dwelling units, this requirement does not apply and no such units are required. Whenever the minimum percentage would yield 151 units or more, the full number is required, unless it is waived under the provisions of footnote 1 in Section 8.3.2.B.1.b.

i.   the Hearing Examiner must transmit the zoning application to the Department of Health and Human Services and to the Department of Housing and Community Affairs within 5 days after the zoning application is filed for their recommendation to the Hearing Examiner;
ii.   the table in Section 8.3.2.B.1.b, containing the minimum requirements for the mixture of residential housing types within a planned development, does not apply to any Independent Living Facility for Seniors or Persons with Disabilities approved under Section 8.3.2; and
iii.   the parking requirements of Division 6.2 applicable to Independent Living Facility for Seniors or Persons with Disabilities may be increased if the development plan proposes a project primarily concerned with providing facilities for independent living.
D.   Compatibility
1.   All uses must:
a.   achieve the purposes under Section 8.3.2.A;
b.   be compatible with the other uses proposed for the planned development; and
c.   be compatible with other uses existing or proposed adjacent to or in the vicinity of the area covered by the proposed planned development.
2.   If a site in a PD zone adjoins land for which the area master plan recommends a Residential Detached zone, the property owner may:
a.   only construct a detached house building type within 100 feet of such adjoining land; and
b.   not construct any building at a height greater than its distance from such adjoining land.
3.   Section 8.3.2.D.2.a may be waived by the Planning Board if the:

Section 8.3.3. T-S Zone

A.   Purpose
1.   The T-S zone is designed to permit development of or additions to planned new towns or additions to existing urban developments. Such towns must contain, to the extent possible, all of the residential, commercial, civic and institutional, and industrial facilities needed to make a town reasonably self-sufficient for all purposes, except major employment and central business district shopping. A development in the T-S zone must:
a.   provide for the maintenance of open space;
b.   locate streets and highways to assure orderly traffic circulation;
c.   include housing for families of low and moderate incomes; and place a wide variety of types of housing accommodations in an efficient and orderly design.
2.   A new town located on a substantially undeveloped site must:
a.   be self-sufficient and contain, as nearly as possible, all of the commercial, employment, cultural, and recreational facilities desirable and necessary for the satisfaction of the needs of its residents;
b.   include a wide variety of residential facilities to offer a wide range of structural types, site planning layouts and arrangements, and rental and purchase prices;
c.   have an urban rather than rural density that would:
i.   facilitate travel between residential, commercial, employment, and other types of areas;
ii.   make the most efficient use of public utilities;
iii.   permit the incorporation of large amounts of open land within the town for recreational and scenic purposes;
iv.   have or plan for the construction of transportation facilities adequate to serve the anticipated total population; and
v.   have public sewer and water available at the site or planned for construction.
3.   The T-S zone is designed to:
a.   eliminate some of the specific restrictions which regulate, in other zoning categories, the height, bulk, and arrangement of buildings and the location of the various land uses;
b.   provide for more flexibility in development;
c.   achieve flexibility of design, integration of mutually compatible uses, and optimum land planning with greater efficiency, convenience, and amenity than the standards permitted by right and required in conventional zoning categories; and
d.   preserve and take the greatest possible aesthetic advantage of trees by minimizing the amount of grading necessary for construction of a development.
B.   Land Uses
1.   A use described on the approved development plan is allowed by right in the T-S zone.
2.   All uses authorized in any zone, by right or as conditional uses, may also be authorized in the T-S zone if the use is shown on the approved site plan or the site plan is first amended under Section 7.3.4.J.
3.   An amendment to the site plan is not required for construction of accessory buildings and additions or modifications to existing detached houses, townhouses, and accessory buildings if:
a.   the Planning Board has approved homeowners association documents establishing a procedure to review such development prior to construction; and
b.   the development is approved under this procedure.
4.   No use may occupy a location other than indicated on the approved site plan.
5.   An area designated as residential on the development plan must only include the residential portion of the T-S zone and accompanying facilities such as local retail areas, public school sites, local recreational and open space areas, and public roads. A residential area must only include:
a.   a detached house used for:
i.   Single-Unit Living;
ii.   a professional office for use by not more than one member of a recognized profession who is a resident of the dwelling and by not more than one nonresident assistant. Recognized professions include medicine, dentistry, law, accounting, and architecture; they do not include businesses such as insurance, real estate, etc. A professional office must be incidental to the principal use of the building as a dwelling and must not include a medical, dental, or veterinary clinic or in-patient treatment facility;
iii.   any other permitted or limited use allowed in the R-90 zone under Article 59-3;
iv.   any conditional use allowed in the R-90 zone under Article 59-3, subject to the grant of a conditional use permit under Section 7.3.1;
b.   an apartment building used for:
i.   Household Living up to the maximum number of dwelling units indicated on the site plan;
ii.   an office for the rental, operation, service, and maintenance of an apartment building or group of buildings;
iii.   any other permitted or limited use in the R-30 zone under Article 59-3;
iv.   any conditional use allowed in the R-30 zone under Article 59-3, which must also satisfy Section 7.3.1;
v.   any commercial use allowed in the NR zone under Article 59-3 if:
(a)   commercial uses are on separate floors than residential uses; and
(b)   the total floor area used for commercial purposes does not exceed the amount indicated on the site plan; and
c.   an Independent Living Facility for Seniors or Persons with Disabilities.
6.   An Antenna on an Existing Structure that satisfies the limited use standards in Section. 3.5.14.C is allowed.
7.   Privately owned roads and community open spaces may be held in perpetuity by the developer or by an approved home owners association with substantial membership and duration if the Planning Board approves easements for such uses granted to the County and recorded in the land records of the County.
8.   All utility lines in the T-S zone must be placed underground. The developer or subdivider must ensure final and proper completion and installation of utility lines under Section 50-40(c). The developer must provide street lighting satisfying the standards contained in the approved site plan. A use-and-occupancy permit must not be issued for any building which is not served by an approved sewer and water supply.
C.   Development Standards
1.   Area Requirements
a.   Each development in the T-S zone must have a minimum area of 1,500 acres unless a sectional map amendment reduces the area zoned T-S to less than 1,500 acres.
b.   A maximum of 10% of the total area of the town sector may be devoted to commercial purposes. All required parking for commercial purposes must be included within the 10% calculation.
c.   A maximum of 6% of the total area of the T-S zone may be devoted to industrial purposes and other major employment facilities.
d.   A minimum of 10% of the total area of the T-S zone must be devoted to open space. This open space may include publicly owned, community-wide, or common open space and facilities, but must not include streets and parking areas.
2.   Density
a.   The population of the T-S zone must be planned for a maximum of 15 persons per acre based upon the total area within the T-S zone. However, the planned population may be increased by an amount equal to the population to be housed in MPDUs included in the development plan under Chapter 25A if the total increase in population does not exceed 22% of the population that would otherwise be permitted.
b.   To calculate density:
i.   dwelling units in detached houses must be assumed to have an average occupancy of 3.7 persons;
ii.   dwelling units in townhouses must be assumed to have an average occupancy of 3 persons;
iii.   apartment buildings less than 50' in height must be assumed to have an average occupancy of 3 persons per dwelling unit; and
iv.   apartment buildings 50' in height or higher must be assumed to have an average occupancy of 2 persons per dwelling unit.
3.   Height
The height of any building in the T-S zone must be consistent with the limits set in other zoning classifications for areas of similar density or similar use.
D.   Procedures for Development
1.   A development in the T-S zone requires site plan approval under Section 7.3.4. The site plan approval must establish standards for width and area of lots, side and rear yards, setbacks, lot coverage, height and grouping of buildings, and similar requirements.
2.   In applying Section 8.3.3.D.1, the Planning Board may waive the substantive requirements of Chapter 50 and certain requirements of Division 6.2 (including the number of parking spaces described in Division 6.2) if it finds that the waiver would allow greater flexibility of development consistent with the purposes of the zone and promote more attractive and more efficient overall planning and design. However, the Planning Board must not waive:
a.   the adequate public facilities requirements of Chapter 50 (Section 50-35(k)); or
b.   the provisions of Section 7.3.4.D through Section 7.3.4.K.
3.   Record plats must indicate that the land is in the T-S zone and include a notation with a statement:
a.   describing all of the land which is designated for common or quasi-public use, but not to be in public ownership. This statement must grant to the public, on such land, easements covering all rights of development, construction or use other than the recreational or other quasi-public uses indicated in the approved site plan, except that, at the time of site plan approval, utilities easements may be excluded from specified areas; and
b.   that the plat satisfies the approved site plan, that development of the land is permitted only if it satisfies the approved site plan, the accompanying agreements concerning the ownership and maintenance of common land are on file at the offices of the Planning Board, and that application for reclassification is prohibited until 50 years after the grant of the T-S zone.

Section 8.3.4. Planned Neighborhood Zone

A.   Purpose
The Planned Neighborhood Zone should facilitate the construction of residential neighborhoods in the County assuming that a neighborhood is an urban area within which the residents may all conveniently share common services and facilities. A development in this zone should:

2.   have adequate retail shopping facilities to provide for the day-to-day needs of the residents of the neighborhood; and
3.   to the extent possible, locate all major transportation arteries at the perimeter of the site. Where this is not possible, a grade-separated pedestrian walkway system must be constructed to provide for safe pedestrian crossing of such heavily traveled roadways. In addition, each planned neighborhood must include bikeways, sidewalks, and other appropriate walkways to provide for safe, direct, and convenient movement of pedestrians to local schools, shopping, and recreation areas.
4.   Moderately priced housing should be available within the neighborhood.
B.   Land Uses
Each use, except any transitory use, must be shown on the development plan for the PNZ zone. A development in the PNZ zone may include:
1.   a detached house used for:

a.   Household Living, up to the maximum number of units indicated on the site plan;
b.   an office for the rental, operation, service, and maintenance of an apartment building or group of buildings;
c.   any other permitted or limited use in the R-30 zone under Article 59-3; or
d.   any conditional use allowed in the R-30 zone under Article 59-3, which must also satisfy Section 7.3.1;
3.   any commercial use allowed in the NR zone under Article 59-3, except a Recreational and Entertainment Facility, located on a property of no more than 15 acres at any one location if:
a.   a market analysis of the local trade area, filed as a part of the development plan, indicates a need for the amount of commercial use proposed; and
b.   the adopted master plan recommends commercial use within the area covered by the application; or
c.   there are inadequate local shopping areas, either existing or proposed on a master plan, within a reasonable distance and with reasonable access from the site;
4.   an Antenna on an Existing Structure that satisfies the limited use standards in Section 3.5.14.C;
5.   a Transitory Use that satisfies the limited use standards in Section 3.5.15.C;
6.   an Independent Living Facility for Seniors or Persons with Disabilities; or

b.   The maximum density of the development may be increased by 112% of the population to be housed in MPDUs provided under Chapter 25A, provided that the total increase in density is increased by no more than 22% of the population which would otherwise be permitted.
c.   Estimated Number of Persons Per Unit
 
Building Type
Persons
For each detached house
3.9 persons
For each townhouse
3.9 persons
For each dwelling unit in an apartment building less than 50' in height
3 persons
For each dwelling unit in an apartment building 50' or more in height
2 persons
2.   Height
The heights of all buildings in the PNZ zone must be consistent with the limitations set in other zoning classifications for areas of similar density or similar use.
D.   Reservation of Land
1.   In addition to land that must be dedicated for public use under Chapter 50, land must be reserved for:
a.   streets as required by the Planning Board and DPS;
b.   public schools as required by the Planning Board and the appropriate staff of the Board of Education;
c.   playgrounds and local parks as required by the Planning Board; and

(Legislative History: Ord. No. 18-08, § 33.)

Section 8.3.6. Planned Cultural Center Zone

A.   Purpose
1.   The PCC zone creates appropriate locations for the development of planned cultural centers within the county. A development in the PCC zone should accommodate cultural arts facilities along with a variety of supplemental uses that relate to the cultural arts in a manner that achieves both physical and aesthetic integration of all uses and activities, including significant open space features and appropriate public use space. The zone uses a more flexible approach to the comprehensive design and development of cultural centers than the procedures and regulations applicable under more traditional zoning categories and other PD zones.
2.   A development in the zone should protect nearby properties and minimize the impacts of cultural centers on the surrounding area, such as visual effects, noise, and traffic. A development that meets the specific standards and requirements of the zone must not be presumed to be compatible with surrounding land uses and, in itself, does not require the District Council to approve the application.
3.   The supplemental uses in Section 8.3.6.B.2 are appropriate only when provided in conjunction with a specific cultural use that is permitted in the zone which would operate on a year-round basis.
B.   Uses
1.   The planned cultural center may include:
a.   an artist studio;
b.   an auditorium for performing arts;
c.   a concert hall;
d.   an educational facility devoted to the arts;
e.   an indoor theater; and
f.   a museum.
2.   If the District Council finds that a specific supplemental use would be compatible with the cultural uses proposed on the site and will not adversely affect surrounding uses because of traffic or other factors, the development may include:
a.   an accessory building and use;
b.   a caretaker's residence or apartment;
c.   a child day care facility, limited to children of persons employed by or using the cultural arts facilities;
d.   a community activities building;
e.   a detached house constructed prior to property being classified in the zone;
f.   a restaurant;
g.   a hotel/motel with no more than 30 guest rooms or suites;
h.   a meeting room and conference facility for the arts;
i.   a publicly owned or publicly operated use;
j.   a residence hall for persons associated with cultural arts uses on the site;
k.   an antenna on an existing structure under Section 3.5.14.C;
l.   a retail establishment for the sale of materials or works of art produced on the premises; and
m.   a workshop used for the construction of scenery and props for use on site or for sale to other theatrical productions.
3.   All uses must meet the purposes of the PCC zone and must be compatible with all uses, existing or proposed, within the site and in the surrounding area.
C.   Development Standards
1.   Setbacks and Screening
a.   Unless the District Council finds that existing topographical features would permit a lesser setback, a building must be set back a minimum of 100 feet from confronting or abutting property that is recommended on the applicable master plan for Residential Detached zoning and development.
b.   A building must be set back a minimum of 30 feet from any boundary line of the site as shown on the development plan.
c.   The maximum building height is 50 feet. However, the building height may be increased 1 foot for every 2 feet of additional setback beyond the minimum required setback, up to a total building height of 75 feet.
d.   Adequate setbacks and screening must be provided for outdoor meeting facilities to ensure against any adverse noise or visual impacts from these facilities on abutting properties.
2.   Coverage and Green Area
a.   The maximum building coverage is 30%. The building coverage may be increased to a maximum of 40% if such additional building coverage is developed and used for above-ground, structured parking.
b.   A minimum of 30% of the total site area included in the development plan must be maintained as green area; however, the District Council may reduce this requirement if it finds that comparable amenities or facilities provided in lieu of green area are sufficient to accomplish the purposes of the zone and would be more beneficial to the proposed development than strict adherence to the specific green area requirements.
3.   Parking
Off-street parking must be provided under Division 6.2.
D.   Procedure for Development
Site plan approval is required under Section 7.3.4.
(Legislative History: Ord. No. 18-08, § 33.)

Section 8.4.3. Public Benefit Descriptions and Criteria

A.   Major Public Facilities
1.   Major public facilities include, but are not limited to, such facilities as a school, library, recreation center, park, County service center, bike share station, public transportation or utility upgrade, or other resource delineated in an applicable master plan. Major public facilities provide public services at a convenient location where increased density creates a greater need for civic uses and greater demands on public infrastructure.
2.   If a major public facility is recommended for a property in a master plan, an applicant for a sketch plan and site plan on that property must provide the major public facility unless the Planning Board finds that the facility:
a.   is infeasible;
b.   would not be accepted by the government department or agency responsible for operating the facility; or
c.   is no longer in the public interest.
3.   If a proposed major public facility is not recommended in the applicable master plan, the Planning Board must find that the facility or improvement provides the community with a resource that is at least as beneficial as other major public facilities recommended in the applicable master plan. Additionally, any infrastructure upgrade may only receive incentive density for improvements beyond those required by any applicable adequate public facilities requirement to complete the proposed development.
4.   Due to their significance in placemaking, the Planning Board may approve incentive FAR for:
a.   the conveyance of a site or floor area for a major public facility;
b.   the construction of a major public facility; or
c.   making a partial or full payment for a major public facility that is accepted for use or operation by an appropriate public agency, community association, or nonprofit organization.
5.   Up to the following number of points may be awarded if the requirements of Section 8.4.4.A are met:
a.   20 points in an LSC zone;
b.   40 points in an EOF or CRT zone; and
c.   70 points in a CR zone.
B.   Transit Proximity
1.   Transit proximity points are granted for proximity to existing or master planned transit stops based on transit service level and CRT, CR, LSC, and EOF zones. Public benefit points can only be granted for one transit stop.
a.   Transit proximity is categorized in 3 levels:
i.   Level 1 is proximity to an existing or master planned Metrorail Station.
ii.   Level 2 is proximity to an existing or master planned station or stop along a rail or bus line with a dedicated, fixed path; this excludes a site that is within one mile of an existing or master planned MARC station.
iii.   Level 3 is proximity to an existing or master planned MARC station.
All distances for transit proximity are measured from the nearest transit station entrance or bus stop entrance.
b.   A project is abutting or confronting a transit station or stop if it shares a property line or easement line, or is separated only by a right-of-way from an existing or master-planned transit station or stop, and 100% of the tract in a single sketch plan application is within 1/4 mile of the transit portal.
c.   For split proximity-range projects:
i.   if at least 75% of the tract in a single sketch plan application is within the closer of 2 proximity ranges, the entire project may take the points for the closer range; or
ii.   if less than 75% of the tract in a single sketch plan is within the closer of 2 proximity ranges, the points must be calculated as the weighted average of the percentage of area in each range.

9.   Way-Finding: Up to 10 points for design and implementation of a way-finding system orienting pedestrians and cyclists to major open spaces, cultural facilities and transit opportunities.
D.   Diversity of Uses and Activities
Development that increases the variety and mixture of land uses, types of housing, economic variety and community activities; contributes to development of more efficient and sustainable communities; reduces the necessity for automobile use; and facilitates healthier lifestyles and greater social interaction.
1.   Adaptive Buildings: Up to 15 points for constructing commercial or mixed use buildings with minimum floor-to-floor heights of at least 15 feet on any floor that meets grade and 12 feet on all other floors. Internal structural systems must be able to accommodate various types of use with only minor modifications.
2.   Care Centers: Up to 20 points for constructing a child, teen, or adult day care facility accommodating at least 15 users that satisfies State standards.
3.   Dwelling Unit Mix: Up to 10 points for integrating a mix of residential market-rate unit types with at least 7.5% efficiency units, 8% one- and 2-bedroom units, and 5% three- or more bedroom units; the proportional number of MPDUs for each unit type must satisfy Chapter 25A.

a.   12 points are granted for every 1% of MPDUs greater than 12.5%. Any fraction of 1% increase in MPDUs entitles the applicant to an equal fraction of 12 points.
b.   An additional 2 points are granted for every 1% of 2-bedroom MPDUs not otherwise required.
c.   An additional 5 points are granted for every 1% of 3-bedroom MPDUs.
d.   For points to be awarded, at least one more MPDU than would be required at 12.5% must be provided to take advantage of the MPDU public benefit points in any zone.
e.   For a project providing a minimum of 15% MPDUs, one less benefit category than is required under Section 4.5.4.A.2 and Section 4.6.4.A.2 must be satisfied. A project that provides a minimum of 20% MPDUs does not have to satisfy any other benefit category under Section 4.5.4.A.2 and Section 4.6.4.A.2.
7.   Small Business Opportunities: Up to 20 points for providing on-site space for small, neighborhood-oriented businesses.
E.   Quality Building and Site Design
High quality design is especially important in urban, integrated-use settings to ensure that buildings and uses are visually compatible with each other and adjacent communities and to provide a harmonious pattern of development. Due to increased density in these settings, buildings tend to be highly visible and high quality design helps attract residents, patrons and businesses to these areas. Location, height, massing, facade treatments and ornamentation of buildings all affect sense of place, orientation and the perception of comfort and convenience. The quality of the built environment affects light, shadow, wind and noise, as well as the functional and economic value of property.
1.   Architectural Elevations: Up to 20 points for providing elevations of architectural facades and agreeing to be bound by particular elements of design, such as minimum amount of transparency, maximum separation between doors, awning provisions, sign restrictions, or lighting parameters that affect the perception of mass, pedestrian comfort, or enhance neighborhood compatibility.

5.   Public Art: Up to 15 points for installing public art reviewed for comment by the Art Review Panel under The Public Art Guidelines approved by the Planning Board, or for paying a fee accepted by the Public Arts Trust Steering Committee.
6.   Structured Parking: Up to 20 points for placing parking in an above or below grade parking structure.
7.   Tower Step-Back: Up to 10 points for stepping back a building’s upper floors by a minimum of 6 feet behind the first floor facade. The step-back must begin at a height no greater than 72 feet.
F.   Protection and Enhancement of the Natural Environment
Protection and enhancement of natural systems and reduced energy consumption help mitigate or reverse environmental impacts such as heat island effects from the built environment, inadequate carbon-sequestration, habitat and agricultural land loss, and air and water pollution caused by reliance on the automobile.
1.   Building Lot Termination (BLT): Up to 30 points for the purchase of BLT easements or payment to the Agricultural Land Preservation Fund (ALPF).
a.   In the CR zone:
i.   An applicant must purchase BLT easements, or make payments to the ALPF, in an amount equal to 7.5% of the incentive density floor area under the following parameters:

(1)   each 31,500 square feet of floor area of residential, nonresidential, and Life Sciences between 0% and 40% of the project's floor area; and
(2)   each 60,000 square feet of Life Sciences between 40% and 50% of the project's floor area.
(b)   any private BLT easement must be purchased in a whole unit; or
(c)   BLT payments must be made to the ALPF, based on the amount established by Executive Regulations under Chapter 2B; if a fraction of a BLT easement is needed, a payment based on the gross square footage of incentive density must be made for at least the fraction of the BLT easement.
ii.   Floor area restricted to the following uses is subtracted from the total density before calculating the required BLTs:
(a)   workforce housing units;
(b)   MPDUs;

Section 8.4.4. Overlay Zones

The following overlay zones have modified public benefits or public benefit calculations which are retained below. These provisions may continue to be used as allowed by the Public Benefit Procedures and Exemptions under Section 4.7.1.D.
A.   Bethesda (BOZ) Overlay Zone Public Benefit Points
1.   Moderately Priced Dwelling Units (MPDUs) Public Benefit Points
a.   The Planning Board may only grant public benefit points for providing more than 15% of the residential units as MPDUs under Chapter 25A.
b.   The Planning Board may grant MPDU public benefit points for providing more than 15% MPDUs at the rate of 15 points for every 1% of the number of units in the project above 15%. Any fraction of 1% increase in MPDUs entitles the applicant to an equal fraction of 15 points. For points to be awarded, at least one more MPDU than would be required at 15% must be provided.
c.   For a project providing more than 15% MPDUs, one less public benefit point category than required under Section 8.4.1.B.8 must be satisfied.
d.   For a project providing at least 20% MPDUs, other public benefit point categories are not required except for: 1) Exceptional Design, and 2) Energy Conservation and Generation in the High-Performance Area.
2.   Public Benefit Points
The requirements for public benefit points for development projects that qualify for an exemption under Section 4.7.1.D are established by Division 8.4, except as provided in Section 4.9.2.C.3. concerning MPDUs and as follows:
a.   The Planning Board must not grant any public benefit points for transit proximity under Section 8.4.3.B.
b.   Park Impact Payment
i.   If a Park Impact Payment is not required under Section 4.9.2.C.2.b.ii and the applicant makes a payment, the Planning Board may grant one point for every $5,000 payment up to 20 public benefit points.
ii.   If a Park Impact Payment is required under Section 4.9.2.C.2.b.ii, the Planning Board may grant public benefit points only if the Park Impact Payment exceeds the minimum required. The number of public benefit points that the Planning Board may grant is determined by dividing the amount of the payment greater than the required payment by the required payment, and multiplying this result by 100.
iii.   The maximum number of points from a Park Impact Payment is 30.
