This section describes the general objectives and intent of Commercial Development Design Standards. (CDDS). The provisions in this section are provided for applicant, Technical Review Committee (TRC), and Planning Board guidance. Specific regulations implementing these objectives and their intent are set forth in the following sections (521.1 - 521.4). The purpose of these standards is to establish and maintain a uniform set of standards that promote the use of high quality design, consistent with the traditional architectural styles of Aquidneck Island and New England.
A. Site Design
Buildings and their adjacent spaces, including parking, establish a design landscape rhythm. This rhythm of spaces and buildings should be considered when determining design compatibility, whether between a building or a building and street. Parking should be considered an integral part of site design and should be coordinated with overall site development. Site design shall encourage pedestrian activity through the placement of buildings close to the street, with off-street parking dispersed into small landscaped lots located to the rear or side of buildings and trees, foliage and grassy areas interspersed among buildings.
B. Building Design and Architecture
In general, buildings shall be designed to include traditional New England architectural elements. This includes, but is not limited to, peaked roof, wood-frame, and other styles consistent with colonial through early twentieth-century period architecture. Facades of a building, particularly the front facade, should consist of or resemble traditional building materials such as clapboard, shingles, brick, or stone. Facades, windows, and doors should be visually proportionate.
Landscaping, including plantings, should be designed to define, soften or screen the appearance of the off-road parking areas and structures from the public right of way and abutting properties. The objective of landscaping should be to enhance the design and minimize the encroachment of the proposed use on neighboring land uses. The species and planting techniques for street-side trees and other plantings should be selected to create a unified image for the street, provide an effective canopy, avoid sidewalk damage, and minimize water consumption.
D. Environmental Impacts
Commercial Development shall be designed to control erosion and sedimentation, stormwater runoff, and minimize impacts on surface water and air quality. Erosion and stormwater runoff control shall comply with town regulations, including Town Code Chapters 151 and 153, as amended. If feasible, efforts should be made to decrease runoff rates and volumes from pre-development conditions.
Signage shall be visually compatible with the scale and character of the surrounding architecture, and should promote traditional architectural elements. The size, location, design, lighting and materials of all exterior signs and outdoor advertising structures shall be compatible with the design of proposed building(s) and structure(s).
Section 521.1 - Site Design
A. General Location and Layout
Buildings should be located so as to create a safe, pleasant walking environment and efficient pedestrian circulation pattern. Building placement, orientation and massing should be planned to promote more active pedestrian-scaled commercial design, with ample opportunities for walking and bicycling, as well as private motor vehicles and to promote the use of public transportation.
B. Off-Street Parking and Circulation
In all districts, except Light Industrial, parking lots should be located to the rear or side of buildings. If site configuration does not allow for the placement of all required parking spaces to the rear or side, a limited number of parking spaces may be located between the front of the building and the public street. Such lots shall be limited to one row of parking, except that for Large-scale Shopping Centers and other situations where site conditions warrant, the use of two rows of parking may be permitted. In either case, the number of parking spaces in such lots shall not exceed fifty (50) spaces, and additional landscaping and screening elements may be required.
In light industrial districts, parking is permitted between building and front lot line only where the front lot line does not abut a public arterial street.
2. Parking Lot Size
The standards of this section are in addition to the requirements of Article 13 of the Middletown Zoning Ordinance regarding off-street parking and loading. No individual parking lot, located between the building and street, may exceed fifty (50) total parking spaces. For a project requiring more than fifty (50) parking spaces, parking shall be broken up into smaller lots; each accommodating no more than fifty (50) vehicles and directly connected with the other lots. Adjacent parking lots must be buffered from each other with a minimum ten (10) foot landscaped strip, which may also be used as a walkway.
3. Access & Circulation
Circulation shall be designed to provide safe and efficient access for pedestrians, automobiles, and emergency vehicles into and throughout the site, including designated pedestrian walkways and crosswalks. Pedestrian access to the site from the public way and neighboring properties shall be provided.
4. Ingress & Egress
(a) Adequate and safe ingress and egress shall be provided. The number and width of curb cuts shall be minimized.
(b) Consolidation of existing curb cuts may be required.
(c) Provision for vehicular and pedestrian connections to adjacent developments shall be provided, whenever possible.
(d) Site design which requires the use of a public street to maneuver in and out of a parking or loading space located on private property shall not be permitted.
All utility lines serving the site shall be installed underground. To the maximum extent possible, power lines and utilities in frontage areas shall be installed underground.
D. Exterior Lighting
1. Exterior lighting shall be designed to minimize impact on neighboring properties and night light pollution.
2. Fixtures illuminating building facades shall be shielded and directed toward the building and all other lighting fixtures shall be shielded and directed to the ground. Building-mounted decorative light fixtures and pole-mounted decorative fixtures, provided that they are less than twelve (12) feet in height, should also be shielded to the extent possible.
E. Infrastructure and Amenities
1. Dumpsters, storage areas, exposed machinery installation including but not limited to HVAC units, service areas, truck loading areas, utility buildings and similar structures shall be designed and screened or located to provide an audio-visual buffer sufficient to minimize their adverse impact on other land uses within the development area and surrounding properties.
2. Air conditioning and ventilation units, security devices, and other service equipment shall be screened from public view, either by being set back from the roof edge for roof mounted units, or by being screened by landscaping for ground mounted units.
3. Litter and Trash Management
(a) Exterior litter receptacles shall be provided on all commercial, multi-family residential, and mixed-use properties to serve patrons, residents and employees.
(b) Receptacles shall be appropriately sized and located. The locations and design of receptacles must be identified on site plans.
(c) Receptacles shall have decorative designs compatible with the overall design theme for the development.
(d) A waste management and litter control plan shall be provided on the site plans or as a separate document, which shall include specific provisions and actions to prevent accumulation of litter on the subject property and to prevent it from entering abutting properties and streets.
4. Bicycle racks shall be provided in appropriate locations and identified on the site plans. Minimum bicycle rack space for one bike for each five automobile parking spaces or fraction thereof is required.
5. The location and design of any proposed site amenities, such as benches, bus shelters, playgrounds, etc. must be identified on the site plans. Designs shall be compatible with the overall design theme for the development.
Section 521.2 - Building Design and Architecture
A. Façade and Walls
The first impression of a building is that of its front façade, the side of the building facing the most frequently used public away. Accordingly, facades and walls shall incorporate the following features:
