[Amended 1-25-2024]
The standards in this section must be applied when a project is classified as a Land Development or when a project requires Development Plan Review in accordance with these Regulations. If either of these projects involves a public right-of-way or installation or connection to infrastructure that serves the public and which must be maintained in accordance with appropriate health and safety standards, the previous section is also applicable.
Vehicular and pedestrian circulation should be clearly organized and functional, providing safe and efficient means of access to all non-sensitive areas of the site. Vehicular and pedestrian circulation areas should be separated to ensure safety, with appropriate linkages at designated inter-modal transportation nodes. A development's circulatory system, including roadways, paths, and parking areas provides the pattern for human experience and should be designed considering both health and safety issues as well as aesthetics, social and environmental issues.
(a) 
Traffic Impact Study Required. In any case where a drive through is proposed or a new building or new use will generate more than 20 additional trips (total of inbound and outbound) during the adjacent roadways peak hours or the development's peak hours or if it is considered that the new development may have an impact on traffic safety, a traffic impact statement may be required. The scope of the traffic study will be defined by the Planning Board. The traffic impact study shall be prepared by a Rhode Island Registered Professional Engineer, specializing in traffic.
The purpose of the traffic impact statement is to determine the proposed development's impact on traffic capacity and traffic safety as well as determine mitigating measures to improve any reductions to capacity and safety. The traffic impact statement shall include the following:
(1) 
A detailed assessment of existing versus proposed traffic conditions on any significant travel ways or intersections that may be impacted due to the proposed development. The analyses will be done using accepted traffic engineering procedures as presented in the 2,000 Highway Capacity Manual of the Transportation Research Board. Projected traffic for the proposed development will be calculated based upon data obtained from Trip Generation, 7th Ed. of the Institute of Transportation Engineers (ITE) or based on information obtained from a similar development. The projected trips are to be added to the existing peak hour traffic count to yield total projected traffic. The proposed conditions are to also include additional traffic generated from the proposed development and any other future development permitted or in the process of being permitted within the vicinity of the project that may impact the traffic conditions. The assessment shall also include a review of the impacts of the project on existing nearby traffic nodes.
(2) 
Accident data for the roads and intersections in the vicinity of the project site will be obtained from the Cumberland Police Department for the latest three years. A traffic safety analyses shall be performed to ensure that no existing safety issues occur within the vicinity of the project. Analyses of the traffic accident data, including discussions with the Cumberland Police Department, will be undertaken to determine whether there are unexpected patterns for an area with the existing geometric and traffic patterns observed. The traffic safety analyses shall include review of the geometric configuration of critical locations with regard to safe stopping sight distance. Based upon principles presented in A Policy on Geometric Design of Highways and Streets of the American Association of State Highway and Transportation Officials (AASHTO) and upon observed vehicle speeds, the adequacy of safe stopping sight distance on all approaches will be determined.
(3) 
An analysis of the interior traffic circulation for a development is to be performed. The analyses is to include both vehicular and pedestrian traffic flow.
(4) 
Based on the results of the above-described analyses, conclusions are to be drawn that will include, as necessary, recommendations for mitigation of the impact of the projected traffic.
Roads and parking areas should be designed to respect natural features and topography, and to present an attractive "streetscape" environment. Vast expanses of paving without visual relief are undesirable. Materials should be harmonious with the existing, surrounding environment. Durable materials such as brick, granite, stone, wood, and textured/colored concrete are preferable.
(b) 
Driveways.
(1) 
Integrate access points for automobiles and pedestrians carefully-especially within the village centers where pedestrian and vehicle traffic co-exist. Driveways should be shared by adjacent developments wherever possible to minimize curb cuts and impervious surfaces unless safety concerns associated with incompatible land uses can not be satisfied.
(2) 
Use special accents at all entries. Monuments, uniquely textured paving, plantings, walls, sculptures, and specimen trees should be used to generate visual interest, and conform to the surrounding context.
(3) 
Every development must have sufficient emergency access as required by existing Regulations and the local Fire, Rescue and Police Departments.
(4) 
Driveway elevations at the property line shall be six inches higher than the elevation curb at the gutter line to avoid flooding of the property from street runoff.
(5) 
Separate customer access and circulation from service truck or delivery access.
(6) 
Roads and driveways should follow existing contours to minimize site disturbance and be designed parallel, rather than perpendicular, to existing slopes.
(c) 
Parking. Off-street parking shall be provided in accordance with the Zoning Ordinance, however, ever, the Planning Board may recommend relief for good cause. In general, where parking areas can be reduced in size, or spaces shared with adjacent businesses, it is considered beneficial to reduce impervious surface areas and maintain a more natural appearance. In order to limit impervious surfaces, parking areas shall not be in excess of the requirements of the Zoning Ordinance.
A Landscaping Sect 2.2.tif
(1) 
The interior of parking areas must be landscaped. Divide large parking lots into a series of smaller connected lots using raised landscape strips at least five feet wide (preferably more) with one shade tree for every 10 spaces (or in accordance with the Zoning Ordinance, the vegetation may be clustered to create one landscaped area for every 20 parking spaces).
A Landscaping Off-Street Parking.tif
(2) 
Each row of parking spaces shall be terminated by landscaped islands which measure not less than five feet wide and not less than 18 feet in length. Terminal islands shall be surrounded by continuous raised curbing and contain two shade trees. Interior islands and divider medians shall be protected from encroachment of motor vehicles in a manner approved by the Planning Board.
(3) 
Lower the grade of parking areas or provide raised berms, where practical and respectful of existing topography, to aid in screening views of automobiles while permitting views of buildings from the right-of-way.
A Use of Grade to Screen Parking.tif
(4) 
Parking areas must be at least five feet from buildings separated by a raised walkway, planting strip, or bollards. There shall be sufficient space directly in front of the building for emergency vehicle access. Parking areas directly abutting the building or right-of-way shall not be considered acceptable.
(5) 
Parking areas shall be located to the rear or sides of buildings out of sight from passing traffic. Vegetative buffering, berms, walls and fences should be used to screen parking to the greatest extent possible from all surrounding areas.
(6) 
Pedestrian walkways should be provided through and between parking areas, buildings and wherever possible to adjacent streets.
(d) 
Drive-Through Facilities.
(1) 
No drive-through facility shall be located in any front yard. Entrances to a drive-through facility shall be offset at least 150 feet from an intersection. No drive-through lane shall exit directly onto a street.
(2) 
A sufficient number of stacking spaces for vehicles waiting to complete a transaction shall be provided so as to prevent circulation congestion, both on-site and on adjacent public streets. In general, the number of stacking spaces shall be based on the following minimum requirements:
i. 
Restaurant: 10 spaces per station.
ii. 
Bank: five spaces for the first station, plus two spaces for each additional station.
iii. 
Other uses: four spaces per station.
(3) 
In addition, there shall be at least one stacking space after the service window, before entrance to a travel lane. Each stacking space shall be a minimum of 10 feet in width and 20 feet in length.
(4) 
Drive-through lanes shall be delineated from traffic lanes and parking areas with striping, curbing, landscaping and/or the use of alternative paving material. Where pedestrians will intersect with a drive-through lane, crosswalks shall be provided, making use of striping and/or alternative paving material.
(5) 
Adequate directional and warning signs shall be provided to assure smooth traffic circulation and pedestrian safety, including marking entrances, exits and one-way lanes of drive-through areas. The placement of all directional signage shall be subject to review and approval under the provisions of these Regulations.
(6) 
Menu boards or other informational boards shall face away from public rights-of-way. All lighting associated with menu boards, window service areas or travel lanes shall be directed and shielded so as to prevent any glare or reflection on adjoining streets or property. The placement of all informational signage shall also be subject to review and approval under the provisions of these Regulations.
(e) 
Pedestrian pathways/sidewalks. Pedestrian systems shall be clearly defined through both the natural and built environments. Attempts should be made to connect pedestrian networks between developments where there exists a logical and practical connection.
(1) 
Within the village centers, sidewalks and paved pathways should be a minimum of four feet wide. Clearly defined pedestrian access should be provided to primary building entrances.
(2) 
The Planning Board may require the construction or reconstruction of sidewalks and curbing in the right-of-way as an off-site improvement.
(3) 
Informal pathways/trails should be provided to connect adjacent natural areas and potential future regional pathways and bikeway.
(4) 
Crosswalks, signs, or other warning cues should be used wherever pedestrians cross traffic aisles.
(5) 
Walkways and open areas shall be generously vegetated.
(f) 
Stairways and ramps. All buildings should be handicapped accessible in accordance with state and federal laws. Provide hand railings in accordance with applicable regulations. Stairs should combine visual attractiveness with safety considerations and provide landings for visual variation and pedestrian rest.
[Amended 9-16-2020 by Ord. No. 20-05B]
(a) 
To the maximum extent possible, the natural landscape shall be preserved. Landscaping shall serve as a unifying element, creating continuous patterns along the street edge and integrating the various elements of site design into the plan with the surrounding landscape elements and processes. In built-up neighborhoods, for example, landscaping which integrates man-made materials, like brick, with plant materials, may be appropriate the closer the building is to the sidewalk. Effort shall be made to use native plants with high wildlife value and aesthetic interest. Plants shall also accent the cultural landscape, providing such elements as rhythm, spatial structure, color, texture, etc. to the built environment.
A Landscaping Sect 3.tif
(b) 
All areas not covered by structures, service yards, driveways, paths, or similar features shall be landscaped. (See § 8-A for the requirements associated with the interior landscaping of parking lots.) The following are planting design concepts that shall be used:
Preservation of existing exemplary or distinctive vegetation, land forms or site features.
Specimen trees in informal groupings and rows at major focal points.
Use of flowering vines on walls and arbors.
Use of planting to create shadow, texture, patterns, rhythm, aroma, color, etc.
Use of trees to create canopy and shade, especially in parking areas.
Use of berms, planting and walls to screen outdoor areas from wind and noise.
The development of sloped properties shall follow the natural contours of the land.
Terraced parking lots, stepped building pads, and larger setbacks shall be used to preserve the general topography of the site and to minimize grade differences between adjacent streets and properties, especially when adjacent downhill properties are residential.
Landscaping around the entire building to soften edges and moderate scale is required, particularly near parking lots, entrances, and other pedestrian areas.
Permanent planters are required for areas not conducive to permanent plantings.
A Landscaping of Yard Areas.tif
(c) 
Landscaped Setback Yards, Berms, Walls, and Screens. Every development or redevelopment shall provide sufficient year-round vegetated set-back yards, berms, walls, and other screens to shield neighboring properties from any adverse external effects of a development, to shield the development from negative impacts of adjacent uses, to minimize stormwater impacts on flood management and water quality, when building design and siting do not provide sufficient privacy, or to aesthetically improve the site by providing barriers to undesirable land uses such as parking lots, utility areas, loading docks, trash pickup areas, and transportation corridors. These barriers may vary in materials and dimensions depending on the intensity of adjacent land uses and other design considerations. The goal shall be to provide as much landscaping as possible from undesirable land uses.
(1) 
Removal of trees (over five inches in diameter) along roadways shall be minimized and in rights-of-way is prohibited.
(2) 
At a minimum, landscaping of all yard areas shall be comprised of a continuous area at least 10 feet wide, except for approved driveways. On an average, this landscaped area shall be planted with grass, shrubs every 20 feet and shade trees (minimum 3 to 3 1/2 inch caliper) planted at least every 50 feet apart. Foundation plantings shall cover at least 60% along each side of a building.
(3) 
Fences and walls shall be architecturally appropriate. Walls shall be terraced with wall sections no more than five feet in height. Chain link fencing shall be prohibited in front and side yards. No fence or wall shall be constructed or installed as to constitute a hazard to traffic or safety.
(4) 
Incompatible land uses shall be segregated as much as possible and in accordance with the buffer distance requirements contained in the Zoning Ordinance. At least 20 feet of the buffer must be landscaped such that the incompatible uses are shielded, screened, or otherwise separated. Landscaping options for screening or buffering include, but are not limited to:
The existing land form, e.g., ledge, or existing mature vegetation.
Evergreen trees (maximum 10 feet on center).
Evergreen hedge, fence, berm, or wall; 36 inches maximum immediately in front of buildings.
Masonry walls consisting of stone, brick, or other similar solid masonry materials or wooden walls coupled with shrubs every 20 feet or trees every 50 feet.
Depressing the parking lot so that its elevation is approximately four feet below adjacent land use.
Rip rap is not an acceptable landscaping option.

No species of plant or large shrub shall be planted under the overhead lines or over underground utilities (as determined by Dig Safe®) if its growth might interfere with the installation or maintenance of any public utilities.
(4) 
Only nursery-grown plant materials shall be acceptable, and all trees, shrubs and ground covers shall be planted according to acceptable horticultural standards. Dead and diseased plants and trees shall be removed and replaced by the owner on at least an annual basis. Failure to properly maintain landscaping may result in such work being performed by the Town at the owner's expense.
(5) 
All landscaping, including that in parking lots, shall be irrigated.
(e) 
Vegetation and Plant Lists.
(1) 
Species shall be suitable for U.S.D.A. Zone 5 hardiness. Use of native vegetation is strongly encouraged, and use of observed or known invasive species is prohibited.
(2) 
Scale of plants shall be compatible with buildings and land use. Plants shall be used to moderate changes in scale. Larger plants can be used to buffer and soften buildings while smaller plants with greater sensory interest can be used in pedestrian areas.
(3) 
The approved plant list reference is entitled Sustainable Trees and Shrubs, third edition, and 1999, authored by the University of Rhode Island Cooperative Extension Landscape Horticulture Program. A list of invasive species is available through the Cumberland Conservation Commission Copies of the entire URI document are available through the Town of Cumberland Planning Department for a fee.
(f) 
Stormwater Management.
(1) 
Natural drainageways should be maintained in an undisturbed state to the greatest extent possible. Retention/detention basins, etc. should only be employed where the natural features cannot adequately control runoff. Stormwater management systems should:
Be designed using non-structural or low-structural components where possible.
Not allow downstream or off-site flooding, soil erosion or other related runoff problems.
Improve the water quality of runoff and protect and restore the quality of ground and surface waters.
Be designed for routine maintenance to be conducted on-site by the owners at regular intervals.
Maintain the natural hydrodynamic characteristics of the watershed.
Be located and designed to minimize aesthetic degradation.
(2) 
All commercial and industrial developments shall use Best Management Practices (BMP) for stormwater management design. Refer to the "Rhode Island Stormwater Design Manual" for suggested BMPs.
(3) 
Any increase in storm runoff should be retained and recharged as close to its place of origin as feasible, using one or more of the following options:
Retention/detention basins.
Porous pavements.
Under-drains.
Surface swales with infiltration drains.
Creative pavement design which can shed surface water to vegetated areas.
Catch basins.
Temporary stone pads at road access point or similar techniques.
Landscaping will be required around visible, above ground control structures.
A Stormwater Mgt_1.tif
(4) 
Water should be managed to decrease velocity, increase infiltration, and allow suspended solids to settle. Preferred options include grassy swales, artificial wetlands, vegetated buffer strips, extended detention basins, infiltration devices, alternative turf and wet retention/detention basins.
(5) 
The siting and physical shape of stormwater management structures including dry and/or wet ponds and swales shall be incorporated into the natural landscape to enhance functional values of the structures and provide visual amenity to the site.
A Stormwater Mgt_2.tif
(6) 
Use porous paving whenever possible. Options include porous asphalt, brick or concrete pavers set on porous base material such as sand, soil cement and gravel.
Site furnishings such as trellises, benches, lighting, trash containers, fencing, phone booths, etc. should be integral elements of the design and should be shown on the plans. Site furnishings shall be placed leaving adequate space for the stockpiling and removal of snow. Exterior vending machines such as soft drink and cigarette dispensers must be screened such that they do not constitute another outdoor sign or advertisement.
(a) 
Lighting.
(1) 
Lighting shall be designed so as not to trespass on adjacent properties or traffic. Lights should generally be directed down.
A Light Trespass Avoidance.tif
(2) 
Upward lighting, such as accent lighting shall be carefully directed away from oncoming traffic, neighboring properties and the sky.

Arbors.
(c) 
Seating/Benches. Rest areas such as benches and wall seating should be provided where pedestrians walk long distances. At least one seat for every 100 feet of pathway is a good rule of thumb. A variety of bench heights should be provided for different uses and user group.
(a) 
New development, modifications and expansions shall be integrated with, and complementary to, existing nearby architecture. Redevelopment projects should reuse existing buildings of character whenever possible. While demolition of buildings is governed by the RI Building Code, demolition of historic buildings in historic districts is also subject to Historic District Commission approval. Similarly, demolition of historic buildings outside of the Historic District Commission's jurisdiction is prohibited and will only be considered after a structural assessment is presented to the Planning Board by a registered architect or structural engineer. Vacant, historic buildings shall be stabilized and preserved until rehabilitated. The focus of the standards and review of building design is to maintain or improve local architectural character.
(b) 
Each building or unit on a site shall have clearly defined, highly visible customer entrances featuring at minimum four of the following:
Recesses/projections.
Arcades, overhangs or canopies.
Raised corniced parapets over the door.

Integral planters or a pedestrian path that incorporates landscaped areas and/or places for sitting.
A Existing Building.tif
A Proposed Renovated Building.tif
(c) 
In general, the architectural style and materials of an existing building should be continued in an addition to the structure. Openings, such as windows and doors, are patterns on a building face and should be considered in the design of an addition. Building form, such as roof lines, should also be considered as the basis for establishing rhythm and proportion.
(d) 
The scale of a new addition should be complimentary to the existing structure; the proportions should not be either too overpowering or too dwarfed. Historic elements or interesting detail should be preserved and incorporated into the overall style of the building.
(e) 
Changes to a building facade should be sensitive to both the overall architectural style of the structure itself and to the architecture of the surrounding area. Historic or architecturally significant buildings shall not be covered over in a way so as to obscure their importance. The proportion and placement of existing doors and windows shall be maintained if those elements are replaced.
(f) 
Facades and Exterior Walls.
(1) 
Exterior elevation drawings shall identify proposed wall materials and depict proposed colors for the project. Building elevations shall indicate window locations, door locations, screening of mechanical equipment and loading dock areas. Building elevations shall be dimensioned to indicate building length and building height in addition to specifying the building roof pitch.
(2) 
Facades should be articulated to reduce massive scale and uniform, impersonal appearances of large buildings and provide visual interest that will be consistent with the community's identity, character and scale.
(3) 
Facades greater than 100 feet in length, measured horizontally, shall incorporate wall plane projections or recesses having a depth of at least 3% of the length of the facade and extending at least 20% of the length of the facade. No uninterrupted length of any facade shall exceed 100 horizontal feet.
(4) 
Commercial ground floor facades that face public streets shall have arcades, display windows, entry areas, awnings, or other such features along no less than 60% of their horizontal length. Windows, doors, and other openings should be detailed to establish them as important parts of the total composition. Design details should be employed to accentuate all entries.
A Articulated Building Facade.tif
(g) 
Roofs.
(1) 
In general, existing roof lines should be maintained. If altered, however, the roof should be compatible in scale and form with the style of the existing portion of the building. Mansard roofs are generally discouraged on one or two story buildings. Roofs should be an integral part of the building design and overall form of the structure and should respond to the general design and nature of other roofs along the street. Roofs shall have no less than two of the following features:
Parapets concealing flat roofs and rooftop equipment such as HVAC units from public view. (see the Zoning Ordinance) The average height of such parapets shall not exceed 15% of the height of the supporting wall and such parapets shall not at any point exceed one-third of the height of the supporting wall. Such parapets shall feature three dimensional cornice treatments.
Overhanging eaves, extending no less than three feet past the supporting walls.
Sloping roofs that do not exceed the average height of the supporting walls, with an average slope greater than or equal to one foot of vertical rise for every three feet of horizontal run and less than or equal to one foot of vertical rise for every one foot of horizontal run.
Three or more roof slope planes.
(2) 
Where a flat roof not meant to be visible from the street is used in the building's design, decorative cornices and parapet walls should be used to delineate the building's profile.
(3) 
Mechanical equipment should not be located on the roof if the building is located below grade of an adjacent road or near an adjacent building that could provide views of the proposed roof, unless the equipment can be hidden from view by building elements that are designed for that purpose as an integral part of the building's design.
A Sample Cond Concealment Rooftop.tif
(h) 
Exterior Building Materials and Colors.
(1) 
Exterior building materials should be aesthetically pleasing and compatible with materials and colors used in adjoining neighborhoods. Urban environments, for example, require the use of hard edge and durable urban materials. Predominant exterior building materials shall be high quality materials, such as: brick, wood, sandstone, other native stone, or tinted, textured, concrete masonry units.
(2) 
Predominant exterior building materials shall not include the following:
Tilt-up concrete panels.
Pre-fabricated steel panels.
Large blank walls.
Flat roofs without a decorative cornice or parapet.
Concrete and cinderblock walls.
Highly reflective surfaces.
Square "box like" buildings.
Mixing of unrelated exterior materials.
Exposed pipe columns.
(3) 
Building elevations should be designed to fit into the surrounding neighborhood. Architectural gimmicks, such as roof lights, distinctive roof shapes, large false cornices and parapets that sacrifice the integrity of a streetscape to promote a single structure are not allowed.
(4) 
Building forms shall be designed to create and define visually attractive exterior and functional spaces.
(5) 
Auxiliary structures should be architecturally consistent with primary structures on site.
(1) 
Signage should be provided for both vehicles and pedestrians. Each development should work within a pre-established "sign envelope" according to the type of sign and size of the development. Envelope size should be proportional to the size of the overall development and immediate streetscape as defined in the Zoning Ordinance.
(2) 
Signs should be simple, easy to read by passing motorists, adequately illuminated, and should complement the color, materials and design of the building architecture. Signs and their illumination shall not adversely impact public safety.
A Signage Program.tif
(3) 
For multi-tenant buildings, a comprehensive signage program shall be developed; only one freestanding sign is allowed.
(4) 
Materials shall be similar to those used in buildings. Signs shall be simple in design, although engraving, molding and other design features can provide a craftsmanlike look.
(1) 
Loading areas shall not be in front of buildings. Loading areas shall be located at the rear or sides of buildings and screen as appropriate.
(2) 
Areas adjacent to residential properties should be free of service circulation unless appropriate landscaping is provided.
