Definitions.
ADULT USEAn adult bookstore, an adult motion picture theater, an adult dance club, an adult paraphernalia store, an adult video store and such other uses as defined and provided for by M.G.L. Chapter 40A, S. 9A.
APPURTENANT STRUCTURESAppurtenances to buildings which are in no way used for living purposes, such as chimneys, towers, spires, stairwell penthouses, and ornamental features, turrets, cupolas or other special features may extend up to 10 linear feet above the maximum permitted height provided the plan area of such features does not exceed 10% of the overall square footage of the roof. Appurtenances shall be a component of the roof design, and not appear to be a leftover or add-on element.
DORMERA structure as part of the roof built with the front wall flush with the wall below, or projected beyond a maximum of two feet, or held back no more than half the length of the main sloped or Mansard Roof, with side walls perpendicular to the pitch of the sloped roof. "Eyebrow" and hip dormers without side walls also shall be defined as dormers. Height of dormer shall be no higher than main roof. Linear footage of dormer shall be measured at the base of the dormer wall, unless the roof intersects the main roof without side walls, in which case the width shall be measured at the mean of the dormer roof.
FLAT ROOFA roof whose pitch is a maximum of 1:12. Height measurements shall be to the perimeter of the roof, or to any level parapet or to the mean of any pitched or radius parapet.
FREEBOARDThe elevation of the building above the National Flood Insurance Program (NFIP) minimum. Freeboard reduces storm and flood damage as well as helping to protect against sea level rise.
GREEN BUILDINGStructures and site that incorporate the following performance elements:
(1) Minimum impact on ecosystems and water resources and water use both inside and out. Highest possible energy-efficiency and use of alternative energy sources including passive solar and/or onsite alternative energy production.
(2) Use of sustainable building materials and reduction of solid waste.
(3) Have indoor environmental quality elements which promote better indoor air quality including natural ventilation and access to daylight and views.
(4) Compact site layouts that enable and promote walking and provide physical connections to a range of transportation modes, open space and other amenities. Incorporation of features for on-site retention, detention and low impact design treatment of stormwater runoff and on-site and off-site stormwater drainage sized to accommodate affects of sea level rise, flooding and increased frequency and intensity of storm events.
GROSS FLOOR AREAThe sum of the floor areas of all the spaces within the building with no deductions for floor penetrations other than atria is the Gross Floor Area (GFA) It is measured from the exterior faces of exterior walls or from the centerline of walls separating buildings but it excludes covered walkways, open roofed-over areas, porches and similar spaces, pipe trenches, exterior terraces or steps, roof overhangs, parking garages, surface parking, and similar features.
HABITABLE SPACEAn area of any structure that is legally accessible and intended for human occupancy for permanent residential or commercial uses. Mechanical rooms, parking areas, storage areas, other passive accommodations or temporary uses shall not constitute habitable space.
HEIGHT OF BUILDINGThe vertical distance above the curb grade, to the highest point of the roof beams of a flat roof or the mean of roof rafters of a sloping roof or to the top of a mansard roof. However, if the natural grade of the ground contiguous to the building is not at the curb grade, the height shall be measured from the mean finished grade at the foundation of the building.
HOTELIs defined as any establishment used for the feeding and lodging of guests which is licensed or required to be licensed under the provisions of M.G.L. Chapter 140, § 6. The definition of a hotel shall not include a motel, lodging house or rooming house.
MANSARD ROOFA roof which forms the walls of the top floor of a building with a Flat Roof above. The pitch of the roof shall be a minimum of 10:12 and maximum of 18:12. Height of Roof shall be measured to the intersection of the Mansard Roof and the Flat Roof above it.
MARKET HALLThe lowest floor of a multi-story structure that is not designed as a habitable space but can be occupied on a seasonal basis, is without permanent walls and is for uses including but not limited to temporary commercial or retail uses, cultural uses, parking (limited to 50% of the area) and shall be open with minimum headroom of eight feet and compliant with lowest floor uses as defined in §
410-4.2 and Subsection
K of the NBOD.
MIXED USE BUILDINGA combination of office, retail and/or residential uses arranged vertically in multiple stories of buildings which are mutually supporting, exhibit physical and functional integration and are developed in conformance with a coherent design. A combination of commercial parking facilities and residential uses shall constitute a mixed use.
MIXED USE DEVELOPMENTA development containing a mix of some or all of multi-family residential, single-family residential, commercial, institutional and other uses, all conceived, planned and integrated to create vibrant, workable, livable and attractive neighborhoods is a mixed use development.
OPEN SPACEOpen Space (OS) is defined as; land that is open to the sky, including natural features of the site and not covered by permanent structures or impervious surfaces; parts of a lot landscaped with trees, shrubs, ground covers and grass, walks, bike trails, terraces, plazas and related pedestrian uses and amenities which may be open to the public or for occupants of lots. Such space may not include lot area used for parking, access drives or other impervious areas intended for vehicular use. OS may include required twenty-foot setbacks where an NBOD project abuts a residence or residential district. OS may include public and private walkways linking OS to public ways and parking and transportation facilities. Impervious surfaces intended for access for those with disabilities are included in the OS calculation. OS under the NBOD shall protect and enhance important natural and cultural resources including but not limited to: natural systems; cultural resources including passive and active recreation; vistas and view corridors, and locations for cultural events and celebrations. Public OS is encouraged in the NBOD.
RESIDENTIAL DISTRICTSAll residential zoning districts defined in the Zoning Bylaw including, Single Family A, B and C and Multi-Family A and B.
SEGMENTATIONDevelopments may not be intentionally divided into parts to avoid compliance with the requirements of the NBOD.
SMART GROWTHWell-planned development that protects OS, revitalizes communities, keeps housing affordable and provides more transportation choices. There are 12 principles that define Smart Growth:
(2) Take advantage of compact building design.
(3) Create a range of housing opportunities and choices.
(4) Provide a variety of transportation choices including walkable neighborhoods and transit oriented developments which reduce vehicle miles travelled.
(5) Foster distinctive, attractive communities with a strong sense of place.
(6) Preserve OS, natural beauty, and critical environmental areas.
(7) Strengthen and direct development towards existing communities with respect for historical architectural context and preservation of significant historical fabric.
(8) Make development decisions predictable, fair, and cost effective.
(9) Encourage community and stakeholder collaboration in development decisions.
(10) Reduce carbon footprint by conserving energy, and by using alternative energy sources.
(11) Building and site design which utilizes passive solar energy and natural ventilation.
(12) Conserving water resources through low impact site design and conservation.
