§ 650-40 Location and height of buildings.

A. 

No building or other structure nor any land shall be used, nor shall any building or structure be erected, except in conformity with the provisions of this chapter and any amendments thereof which apply to the district in which the building, structure or premises shall be located.

B. 

No three-family dwelling, multifamily dwelling, two-family dwelling having two or more lodgers in addition to the family units contained therein, nor boardinghouse having facilities for four or more lodgers located in a district in which the building is otherwise permitted or exceeding 2 1/2 stories in height shall be erected or created through conversion or otherwise unless a special permit is granted in each case by the City Council after a public hearing, except as may otherwise be specifically provided in this chapter.

C. 

A minimum accessway of at least 30 feet in width is required for any and all multifamily dwellings.

D. 

Within any district, no building, structure or lot shall be used or arranged or designed to be used in any part for any trade, business, industry or purpose of any kind that is noxious or offensive by reason of the emission of odor, dust, refuse matter, vapor, smoke, gas, noise, vibration, wastes or combination of wastes, which because of its quantity, concentration or physical, chemical or infectious characteristics may cause or significantly contribute to an increase in mortality or an increase in serious irreversible or incapacitating reversible illness or pose a substantial present or potential hazard to human health, safety or welfare or to the environment when improperly treated, stored, transported, used or disposed of or otherwise managed.

E. 

No uninhabitable structure which exceeds 30 feet above the ground shall be located in any district, unless otherwise provided.

F. 

For the purposes of this chapter, all principal buildings may be built on any lot located in a district in which the building is permitted, provided that:

(1) 

The lot has frontage abutting a public or private way or on a way shown on a plan previously approved under the Subdivision Control Law or on a way which existed when the Subdivision Control Law became effective and which, in the opinion of the Planning Board, has sufficient width, suitable grades and adequate construction to provide for vehicular traffic and for the installation of municipal services.

(2) 

It is located so as to comply with the following requirements for height and yards.

Editor's Note: See § 650-41 and the Table of Lot Area, Yards and Height at the end of this chapter.

(3) 

No building in any district need be located or placed further from the exterior line of any street or public way than the average distance from such street or way line of the dwellings or other principal buildings located on the lots adjacent thereto on either side. In determining such average, a vacant side lot having a frontage of 50 feet or more shall be considered as though occupied by a building having the required setback, and a lot separated from the lot in question only by a vacant lot having a frontage of less than 50 feet shall be deemed an adjacent lot.

(4) 

The front, side and rear yard provisions hereof may be varied by the Board of Appeals in the specific case of an irregular, narrow or shallow lot or a lot unusual either in shape or topography, provided that in the opinion of the Board it is impossible or extremely difficult to adhere to such provisions.

(5) 

Nothing herein shall prevent the projection of cornices or eaves not exceeding 18 inches in width or of uncovered steps, unroofed porches or window sills into a required yard or other open space.

(6) 

In all districts except within the flight path of commercial or governmental airports, farm buildings, churches, municipal or institutional buildings and spires, domes, steeples, radio towers, chimneys, broadcasting and television antennas, bulkheads, cooling towers, ventilators and other appurtenances usually carried above the roof may have any height.

(7) 

Every building shall have frontage on a way, public or private, or a clear unobstructed passageway at least 20 feet wide for its entire length over the lot on which it is located to said way. If a building is located in the rear of another building located on the same lot, the open space between such buildings shall be at least 50% greater than the rear yard requirement for the district. The rear building shall be subject to side and rear yard requirements of the district in which it is located. For purposes of this Subsection F(7), separate buildings within a shopping mall or retail lot shall be treated as a single building.

(8) 

In all districts in which multifamily dwellings are allowed, there shall be provided with each apartment building a landscaped area equal to the greatest single floor area of the building.

(9) 

Land used for outdoor storage for commercial purposes shall be screened from streets abutting the property and for adjacent properties by a solid fence of sufficient height to obscure materials stored therein. Affected parties shall be given six months from date of adoption of this chapter to comply.

(10) 

Bridges, walkways or passageways, enclosed or otherwise, connecting buildings located on a large tract development lot shall not negate the existence of each such building as a separate building, and each building so connected shall be deemed to be a separate building for all purposes of this Zoning Ordinance.

§ 650-41 Table of Lot Area, Yards and Height.

(The Table of Lot Area, Yards and Height of Structures is included at the end of this chapter.)

§ 650-42 Size of lots.

For the purposes of this chapter, all principal buildings may be built on any lot located in a district in which the building is permitted, provided that the lot complies with the requirements included in the Table of Lot Area, Yards and Height of Structures, except where specifically provided otherwise by this chapter, and further provided that:

A. 

Lot area requirements.

(1) 

Lot area.

(a) 

Minimum lot area. The lot contains the minimum area required.

(b) 

Minimum area for principal building. The minimum lot area shall not be counted for more than one principal building, except in the case of:

[1] 

Limited Industrial and Industrial Districts.

[2] 

Multifamily dwellings located in any district where said dwellings are permitted, subject to requirements specified elsewhere in this chapter for said dwellings.

(c) 

Single- or two-family dwellings. In all districts in which single- or two-family dwellings are allowed, only one principal building containing said one- or two-family dwelling shall be permitted on any one lot, no matter what the lot area, unless said lot is located in a district where more than one of said principal buildings is specifically permitted by other provisions of this chapter.

(d) 

Area within street not included. In determining lot area, no part thereof within the street lines or within a private road or right-of-way for travel by motor vehicles to another lot shall be included. Street lines shall determine lot boundaries.

B. 

Lot shape. The lot shall be large enough to contain a rectangle having one side equal in length to the required frontage and situated parallel to the mean direction of the front lot line and the other side equal to 3/4 of the required frontage. Where the front lot line is curved, the mean direction of the front lot line shall be the line established by connecting the intersection points of the side property lines with the street line. Said rectangle shall touch the front lot line, but no part of said rectangle shall intersect any lot line.

C. 

No lot on which a building is located in any district shall be reduced or changed in size or shape so that the building or lot fails to comply with the lot area, frontage, setback, yard or height provisions of this chapter applicable to the construction of the building on the lot. This provision shall not apply, however, when a portion of a lot is taken or conveyed for a public purpose.

D. 

On corner lots, the setback provisions governing the location of the building shall apply in relation to both streets or ways.

E. 

Any lot or lots of land described in a deed and officially recorded with the Registry of Deeds or included in a subdivision approved in writing in accord with the Subdivision Regulations of the Planning Board of Marlborough by said Board at the time of the adoption of this chapter may be used for any permitted use in the district in which the lot or lots are located, provided that:

(1) 

In the case of a nonconforming lot, the adjoining lot is not vacant and not in the same ownership.

(2) 

Any lot on which more than one house existed at the time of the adoption of this chapter may be divided and sold to separate owners and used with a minimum of nonconformance.

F. 

Any increase in the area, frontage, width, yard or depth requirements of this chapter shall not apply to a lot to be used for dwellings with one- and two-dwelling units which, at the time of recording or endorsement, whichever occurs sooner, was not held in common ownership with any adjoining land; conformed to then-existing requirements and had less than the proposed requirement but at least 5,000 square feet of area and 50 feet of frontage. The provisions of this subsection shall not be construed to prohibit a lot being built upon if, at the time of the building, building upon such a lot is not prohibited by this chapter.

G. 

In the application of the requirements of this chapter, including, without limitation, those set forth in §§ 650-42, 650-43, 650-45, 650-47 and 650-48, the same shall not be applied to the individual lots comprising a developing lot or a retail lot but shall be applied as if the development lot or a retail lot were the lot, notwithstanding the fact that the individual lots within the development lot or a retail lot may be in different ownership.

§ 650-43 Maximum lot coverage.

A. 

Structures in all zones together with all parking and driveways shall conform to the maximum lot coverage provision indicated in the Table of Lot Area, Yards and Height of Structures.

Editor's Note: The Table is included at the end of this chapter.
Within a Limited Industrial District, maximum lot coverage for development of a shopping mall on a development lot may be increased to 85% when approved by the City Council, as provided in § 650-59, in writing, provided the City Council finds that, in connection with such development, infrastructure improvements are to be made by the applicant that will benefit not only the development but other property within the City.

B. 

Maximum lot coverage for development of retail stores, shops, restaurants or service establishment uses, excluding automotive service establishments (such as gasoline filling stations and places for the repair and service of motor vehicles), on a retail lot may be increased to 85% when approved by the City Council, as provided in § 650-59, in writing, provided the City Council finds that, in connection with such development, infrastructure and/or open space improvements are to be made by the applicant that will benefit not only the development but other property within the City.

§ 650-44 General off-street requirements.

A. 

Underground utility lines. All electric, telephone, cable television and other utility lines shall be installed underground, subject to the approval of the City Engineer. This requirement shall apply to all new structures and all additions and major renovations to existing structures requiring site plan approval.

B. 

Refuse areas required. In all districts all structures except one- and two-family dwellings shall be provided with an area or areas suitable for storage of refuse and like matter, in compliance with regulations of the Board of Health, screened as required in this chapter, located away from living quarters and within the setback requirements for accessory buildings. Said refuse or like matter shall be removed and disposed of periodically and as required to prevent accumulations and to further ensure the health and safety of the tenants of such building or buildings or of abutters and to protect the property values of abutting property.

C. 

Identification of buildings. All buildings shall be identified as follows: There shall be attached the number of each building, issued by the City Engineer at the time of site plan approval, in letters or numbers a minimum of four inches high, in at least one location clearly visible from the street and in any event at the front entrance of all buildings and the rear entrance of multifamily and nonresidential buildings.

§ 650-47 Landscaping and screening.

Editor's Note: Landscaping and screening diagrams are included at the end of this chapter.
A. 

Objectives. The provisions of this section are intended to achieve the following purposes:

(1) 

To provide a suitable boundary or buffer between zoning districts.

(2) 

To separate different and otherwise incompatible adjacent land uses from each other in order to partially or completely reduce potential nuisances, such as dirt, dust, litter, noise, glare from motor vehicle headlights, the intrusion from artificial light, including the ambient glow therefrom, signs or the view of unsightly buildings and parking lots.

(3) 

To provide visual relief to parking lots and protection from wind in open areas.

(4) 

To preserve or improve the visual and environmental character of a neighborhood and of Marlborough generally.

(5) 

To offer property owners protection against possible diminution of property values due to adjacent commercial construction or a change in existing ostensibly incompatible land uses.

(6) 

To assure public safety requirements for sight distance visibility.

B. 

Applicability. Landscaping, planting areas and screening shall be provided in accordance with all provisions of this section as specified below:

(1) 

When the building or site undergoes a change of use or is enlarged by more than 10% of the floor or ground areas of use or when any new principal building is built on the site or when any new building, addition, alteration or change of use requires a parking increase of five or more spaces.

(2) 

Compliance with all provisions of this section to the maximum extent practicable, as determined at site plan approval, shall be a requirement for approval of any site plan or off-street parking plan or issuance of any building permit, occupancy permit or special permit.

(3) 

An application for a special permit for a use, structure or activity that does not comply with the provisions of this section shall not be granted until compliance to the maximum extent practicable is demonstrated.

C. 

Landscaping plan required.

(1) 

A landscaping plan demonstrating compliance with the standards contained in this section for landscaping, planting areas and screening shall accompany each application for site plan approval and building permit. The plan shall be drawn to scale and may be part of a site plan application. A landscaping plan shall not be required for a single- or two-family dwelling.

(2) 

The landscaping plan for any lot used or zoned for multifamily or nonresidential use shall be certified by a landscape architect registered in the Commonwealth of Massachusetts.

(3) 

The landscaping plan shall show, apart from information normally required on a site plan:

(a) 

A layout plan showing existing and proposed grades, the proposed landscaped area and planting areas, the existing plant materials to be retained, the proposed plant materials to be provided and the location, size and type of such plant materials and of any nonplant materials to be retained or provided.

(b) 

A plant schedule giving botanical and common names of plants to be used, size at time of planting and quantity of each.

The methods for protecting plant materials during and after construction.

D. 

Planting area requirements. The following requirements shall apply to all planting areas required by this section, except as provided hereinafter:

(1) 

Planting areas and lot coverage. Planting areas on a lot shall be considered a part of the total landscaped area on a lot required by the maximum lot coverage provisions of § 650-43. Any landscaped area required by the lot coverage provisions and located outside of a planting area required by this section shall meet the requirements of Subsection D(3), Ground surface materials, but need not meet the requirements of Subsection D(4) or (5) for planting type and size and planting quantity and spacing.

(2) 

Location. The planting area required by this section shall be located entirely within the lot. Additional planting area may be provided outside the lot but shall not be credited to the area required within the lot.

(3) 

Ground surface materials.

(a) 

Paving. The planting area shall not be paved over with asphalt, concrete or similar material, or covered with gravel, except for access drives and walks located essentially perpendicular to the area. No structure, parking area or paved play area may be located in a required landscape area.

(b) 

Plant materials. The planting area shall have a ground surface cover of live plant material, such as lawn grass or live ground cover, over at least four inches of topsoil, except that bark mulch may be used in place of live ground cover, and except for nonplant materials solely as provided for hereinafter under Subsection D(3)(d).

(c) 

Substitution with artificial plants. The substitution of artificial shrubs, grass or other plants shall not be permitted.

(d) 

Nonplant materials. Nonplant ground surface material, such as brick, decorative stones or other similar material (but not gravel, concrete or asphalt paving), may be used in place of live plant material or bark mulch, provided that the nonplant material covers no more than 30% of any planting area required by this section and has shrubs and trees distributed over its surface as required below under Subsection D(5).

(4) 

Planting type and size. Required plantings shall include both trees and a mix of deciduous and evergreen shrubs to maintain effectiveness throughout the winter and preferably will include vegetation existing on the site. To be credited towards meeting these requirements, trees must be at least two inches caliper four feet above grade at the time of planting, be of a species common in the area and which reach an ultimate height of at least 20 feet when mature. Shrubs must be at least 12 inches in height at the time of building occupancy and be of a species common in the area. Live ground cover, lawn grass or hedgerows may be substituted for shrubs as provided under Subsection D(5) below.

(5) 

Planting quantity and spacing.

(a) 

Plantings shall consist of at least one shrub per five linear feet or 35 square feet of ground area, whichever results in a greater number of shrubs, and at least one tree per 40 linear feet of planting area length, except one tree per 30 linear feet of street frontage planting area abutting Routes 20 and 85.

(b) 

Planting layout. Plantings may be grouped, not evenly spaced, but groups of shrubs shall be spaced no further apart than 10 linear feet and groups of trees no further apart than 50 feet.

(c) 

Substitution of shrubs with lawn grass or ground cover. Shrubs required by this section may be substituted with live ground cover or lawn grass, but not bark mulch or nonplant ground surface material, under the following conditions. To be credited for substitution:

[1] 

The substitution may occur in the street frontage planting area but not in the side line or district boundary planting areas.

[2] 

The substitution must be in a contiguous area of not less than 100 square feet.

[3] 

No more than 50% of the total number of shrubs otherwise required in the entire frontage landscaped strip may be substituted in the above manner.

[4] 

No substitution may be made for tree plantings required by this section.

[5] 

The lawn grass or live ground cover must be properly maintained in presentable appearance. Additional areas of live ground cover or lawn grass may be provided in planting areas but cannot be used in substitution of the required number of shrubs or trees.

(d) 

Substitution of shrubs with hedgerow. Shrubs required by this section may be substituted in full by a continuous hedgerow not less than two feet high when planted and attaining a height of at least three feet within three years. Such substitution may be made in any planting area, provided that live ground cover or lawn grass is planted in the remainder of the planting area along with the hedgerow. Trees may not be substituted with hedgerows.

(e) 

Egress visibility. Plantings shall be located or trimmed to avoid blocking egress visibility. (See Subsection N, Sight Distance.)

(6) 

Existing vegetation. Wherever possible, the above requirements shall be met by retention of existing plants, including as follows: If located within the street frontage planting area required by this section, no existing tree of six inches in caliper or greater (measured four feet above grade), dense hedgerow of four or more feet in both depth and height, or existing earth berm providing similar visual screening shall be removed or have grade changed more than one foot unless required by plant health or access safety.

(7) 

Curb protection of landscaping from vehicles. Except for single- and two-family dwellings, wherever landscaping areas are adjacent to parking areas or driveways, the landscaped areas shall be suitably protected by raised curbing to avoid damage to the plant materials by vehicles and by snowplows and to define the edge of the landscaped area. The edge of the landscaped area shall also be defined by tall stakes during winter season. Curb specifications for parking areas and driveways are included in § 650-49.

(8) 

Walls or fences. Walls or fences may not be substituted for plant materials to reduce the required planting area. A wall or fence may be added where a mass of plant materials would not provide an adequate screen, in which case planting shall be provided along the side of the wall or fence.

E. 

Street frontage planting area.

(1) 

Location and width.

(a) 

A continuous landscaped strip shall be provided adjacent to the right-of-way line of any street (existing, proposed, paper, public or private) or highway, except for driveways or walkways located essentially perpendicular to the street frontage. This landscaped strip shall have a minimum width as prescribed below, provided that said minimum width shall be increased if required by provisions of Subsection E(1)(b) following, and also provided that, if the front yard (building setback) as built, not as required, is less than the width of the landscaped strip, then the landscaped strip may be reduced to not less than the depth of the front yard. Said minimum width shall be as follows.

[1] 

One- and two-family dwellings: the minimum width of the required front yard.

[2] 

Multifamily dwellings: the minimum width of the required front yard.

The maximum required width for said street frontage landscaped strip shall be 25 feet.

(2) 

(Reserved)

(3) 

Planting in right-of-way. The landscaped strip adjacent to the right-of-way required by this section must be located within the affected parcel, and state or City property within the right-of-way may not be used to meet the requirements of this section. However, wherever possible, the extension of grass or ground cover into said right-of-way is encouraged but must be approved on the landscaping plan and maintained by the owner of the affected parcel.

(4) 

Planting requirements.

(a) 

For other than residential uses in all districts, the street frontage planting area shall be planted with trees and shrubs according to Subsection D, Planting area requirements, entirely within the frontage planting strip next to the right-of-way.

§ 650-49 Driveways and curb cuts.

A. 

Purpose and objectives.

(1) 

Purpose. The purpose of this section is to ensure adequate access for traffic generated by development and for emergency vehicles; to increase public safety for vehicles and pedestrians; and to reduce traffic congestion, dust and erosion within the development and in adjacent public ways.

(2) 

Objectives. The means to accomplish this purpose shall include reducing the number of driveway openings onto public streets; regulating the spacing, design and construction of driveways; requiring joint or shared use of driveways; and requiring off-site improvements where appropriate as specified in the following subsections.

B. 

All driveways. All driveways for all uses in all districts shall comply with the following minimum requirements:

(1) 

Road opening/curb cut permit required.

(a) 

Anyone wishing to construct a driveway on a lot having frontage on a public way or a way which the Clerk of the City certifies is maintained and used as a public way or a way shown on a plan heretofore approved and endorsed in accordance with the Subdivision Control Law or a way in existence when the Subdivision Control Law became effective in the City having, in the opinion of the Planning Board, sufficient width, suitable grades and adequate construction to provide for the needs of vehicular traffic, shall first obtain site plan approval followed by a road opening/curb cut permit from the City Department of Public Works.

(b) 

In all cases, said permit shall be limited to the project granted site plan approval. Any substantial change in use of the curb cut (see below) shall require modification of the permit or application for a new permit which may contain new restrictions. "Substantial change" shall mean an increase of 10% or more in vehicle trips caused by expansion of the project or by a change of use from one use category to another as listed in § 650-48 of this chapter, or by addition of a drive-through facility, or a substantial impact on traffic caused by a change in the type, pattern or timing of such traffic.

(2) 

Location.

*** Width must be increased if driveway is used as parking aisle. See § 650-48C(3) and (4) for parking aisle dimensions.
F. 

Common driveways. Common or shared driveways shall be permitted, provided that they meet the following requirements:

(1) 

Purpose and approval. A common driveway shall not be permitted unless said driveway is determined at site plan review and approval to provide a reasonable public benefit which would not otherwise be obtained without use of a common driveway. Said benefit or purpose may include reduction in the number of curb openings or driveways onto major streets or at unsafe or unsuitable locations which can be avoided by provision of common or shared driveways.

(2) 

Number of single-family lots. No more than five single-family residential lots shall be served by a common or shared driveway, unless permitted under the provisions of the Subdivision Control Law or under an approved site plan as provided for in this chapter. Notwithstanding the foregoing, owners of lots developed under an approval-not-required plan in accordance with and permitted by Massachusetts General Laws may use a common driveway for more than five residential structures, provided that such driveway meets minimum road standards of the City as specified in the Rules and Regulations of the Planning Board for Subdivisions, unless such standards are modified during site plan review.

(3) 

Number of lots other than single-family lots. The number of lots, other than single-family lots, shall be determined on a case-by-case basis, based upon determination that safety will be adequately protected and that commonly employed engineering and planning standards have been met in full.
