Relationship of buildings to lots.
Every building hereafter erected shall be located on a lot as defined in § 280-2-2: Definitions. In no case shall there be more than one (1) principal residential building and its accessory buildings on one (1) lot, except in the case of projects such as multiple dwelling or building developments intended and designed to be managed as a unit on an unsubdivided lot.

Access of lots to streets.
No building shall be erected on a lot unless the lot has frontage on a street as defined in § 280-2-2: Definitions.

Creation of lots along arterials.
The following limitations shall apply to the creation of all new lots on all land located adjacent to Route 4, Route 109, Route 202, Route 11A and Route 224.

A. Access to new residential lots. Any new residential lots created adjacent to the principal arterials listed above shall be divided so that vehicular access to the lot is obtained from a local or collector street rather than the arterial. Access to the new lots shall be obtained from any local or collector street, a street in an approved subdivision, or a private way approved by the Planning Board. This requirement shall apply to any new lot whether, or not, the lot is part of a subdivision.
B. Waiver of the access limitation for new lots.

(1) The Planning Board or Site Plan Review Committee may waive the access limitation provisions of this subsection when there are unique conditions which make access, other than from the arterial impractical. The Planning Board may grant a waiver only if one (1) of the following conditions is met:

(a) There is too little road frontage to reasonably allow for the creation of a local street, and there will be no further subdivision of the lot; or
(b) The shape or physical condition of the lot does not permit access to or the creation of a local street, and there will be no further subdivision of the lot.

(2) The owner of the lot seeking a waiver shall make a written request to the Planning Board setting forth how the project conforms to the above criteria.

C. Existing lots. Any lot of record existing as of the date of the adoption of this section shall be permitted one (1) vehicular access point to a principal thoroughfare, notwithstanding the provisions of this chapter, unless such lot also has frontage on a local street.

All use of land, buildings, and structures shall conform to the requirements of Chapter 178: Noise.

A. Applicability. Off-street parking shall be provided for all new construction, expansions, and changes of use in accordance with the requirements and standards of this section.

B. Minimum requirements for off-street parking. Off-street parking shall be considered an accessory use when required or provided to serve any legal use located in any zone. An off-street parking space shall be a minimum of nine (9) feet wide by eighteen (18) feet long and may be open or covered. Access to individual parking spaces shall be unobstructed except for parking for residential uses. Parking for single and two (2)-family dwellings may be arranged in a stacked layout so that access to one (1) space is over another. Stacked parking may also be used for multifamily residential uses if the parking spaces are assigned to units and the access to one (1) unit's parking space is not obstructed by the parking space of another unit. In order to determine compliance with this section, the Code Enforcement Officer shall require a plan showing the physical layout of all required off-street parking areas. Any change in the evidence or conditions upon which the plan is approved shall nullify such approval.

(1) Parking shall be provided on the lot occupied by the use for which the parking is required or on an adjacent lot owned or controlled by such use. In addition, uses located within the Urban Zone may provide all or part of the required off-street parking through any of the following:

(a) Private off-street parking located on another lot that is located within one-thousand (1,000) feet of the subject lot and that is controlled by long-term lease or ownership by the proposed use.
(b) Off-street parking shared with other uses located within one-thousand (1,000) feet of the subject lot, provided that the Planning Board or Site Plan Review Committee finds that there is adequate parking capacity to meet the parking requirements of all uses sharing the parking due to variation in the time of parking demand and/or anticipated use of parking to access multiple uses in a single trip, and that the shared parking is controlled through a leasehold or other enforceable agreement. The Planning Board or Site Plan Review Committee may allow off-site parking to be more than one-thousand (1,000) feet from the site if it finds that the distance is reasonable given the nature of the proposed use.
(c) For nonresidential uses, off-street parking located in a municipal parking lot provided by the City, subject to the Planning Board or Site Plan Review Committee finding that there is adequate available parking to meet the needs of the use based on the parking standards of this chapter. The Planning Board or Site Plan Review Committee may allow legal on-street parking to be used to meet the parking requirement of a nonresidential use in the Urban and Industrial Redevelopment Zones if it finds that this parking can reasonably be expected to be available for customers of the use and is located within close proximity of the use.

(2) Where multiple use of a lot occurs, off-street parking shall be provided for each use in accordance with this section. Where the applicant can demonstrate and document nonconflicting periods of use, shared use of parking spaces may be permitted by the Planning Board or Site Plan Review Committee.
(3) Travel and queuing aisles associated with off-street parking, drive-in facilities and motor vehicle fuel pumps shall be provided and shall not interfere with the use of or be part of the required off-street parking.
(4) Minimum number of parking spaces required.

(a) The following minimum number of spaces, rounded up to the nearest whole number, shall be provided and maintained for each use on a lot, including each use within all buildings. The Planning Board or Site Plan Review Committee may reduce the required parking:

[1] For reuse of an existing building by up to thirty percent (30%). In granting a reduction, the Planning Board or Site Plan Review Committee shall find that the reduction will not create or worsen parking problems in the neighborhood and that the required number of spaces cannot be reasonably accommodated on the lot; or
[2] For new or existing buildings, if the applicant demonstrates to the Planning Board or Site Plan Review Committee that proposed parking is adequate for the use based on national or regional parking demand studies such as those published by the Institute of Traffic Engineers or by data on actual parking demand for similar uses in similar situations and/or consideration of the availability of parking demand management programs that reduce the demand for on-site parking.

(b) The maximum number of employees scheduled during peak demand/shift shall be used in calculating the number of required parking spaces when employee is referenced in the list below. Gross floor area shall be used in calculating the number of required parking spaces, unless otherwise noted.

For information on specific parking requirements for certain land uses, see Parking Table.
 

C. Off-street parking design standards. The following design standards shall apply to all new and expanded off-street parking areas:

(1) Parking areas for uses other than single- and two (2)-family dwellings shall be designed so that vehicles will not back out into a street.
(2) Parking areas shall not inhibit emergency vehicle access to any building or structure.
(3) Parking areas shall be separated from the front of all buildings by a landscaped area at least five (5) feet wide.
(4) Wheel stops/curbs shall be placed where needed to prevent encroachment into walkways, landscaped areas, circulation aisles, streets and structures.
(5) Where possible, parking spaces and travel aisles shall be clearly delineated.
(6) All parking areas shall be designed to adequately control drainage. In furtherance of this standard, drainage calculations used shall reflect a paved condition, and all parking areas shall be constructed with base material which can withstand normally expected vehicle loading and winter maintenance.
(7) In lots with ten (10) or more parking spaces, at least five percent (5%) of the parking spaces shall be designed and designated for handicapped parking. These spaces shall be located in close proximity to the entrances to the building.

Notwithstanding other provisions of this chapter, the following structural elements may project into a required setback as set forth below:

A.  A cornice, eave, or canopy or other similar architectural features, but not including a bay window, may project up to two (2) feet into required setbacks.
B. A fire escape may project up to four (4) feet into required setbacks.
C. A chimney may project up to two (2) feet into required setbacks.
D. An open, unenclosed platform, stoop, or steps, not covered by a roof, may project up to six (6) feet into required setbacks. The platform or stoop shall be no more than sixteen (16) square feet.

E. Any porch with a roof that existed as of the date of adoption of this provision may be enclosed and used as living area even if it currently encroaches on the required setback. The enclosed porch shall not further encroach on the setback but it may be enlarged in such manner as to maintain the existing relationship to the property line.

F. Facilities for handicapped access, including ramps, lifts, and elevators, added to a building constructed prior to December 30, 1990, may project into any required setback area provided that the facilities are approved by the Fire Department on the basis that they will not create or aggravate any public safety or fire-fighting issues.
G. Signs consistent with the requirements of § 280-14-13B.

A rear lot is a lot which is located to the rear of another lot or lots which front on a street as defined in this chapter. A rear lot existing as of the date of adoption of this section may be used for uses allowed within the zone in which it is located provided that:

A. There is an unobstructed access to the rear lot from the street over land which is not needed to meet the minimum requirements of the zone for the front lot.
B. Access is at least twenty-five (25) feet wide.
C. The access strip is in the same ownership as the rear lot.
D. The access strip may not be used to meet the requirement for minimum lot size of the zoning district.
E. The rear lot shall meet all requirements of the zoning district, other than minimum frontage. For the purpose of setback requirements, the setback line of such lots is deemed to be the prescribed setback distance from the deepest rear property line of the lot or lots between said rear lot and the nearest street.

The purpose of this provision is to maintain a clear line of sight for drivers of vehicles at street and driveway intersections. This requirement shall apply to buildings, structures, fences, signs, landscaping or other elements.

A.  Within the Urban Zone, no visual obstruction that interferes with a vehicle operator's line of sight shall be located within the triangular area created by measuring ten (10) feet back from the point of intersection of the travel way of two (2) streets or a street and a driveway and connecting these points.

B. In other zones, no visual obstruction shall be located within the triangular area created by measuring twenty-five (25) feet back from the point of intersection of the travel way of two (2) streets or a street and a driveway.

C. Existing trees shall not be considered to be visual obstructions, nor shall objects located within thirty (30) inches of the ground or located more than six (6) feet above the ground. Any landscaping within this area shall be maintained so that a clear line of sight is retained at all times.

A. Applicability. All signs erected, altered, displayed, or maintained in all areas of the City and visible from a street shall meet the standards of this section.
