(1) The development shall be planned so that a common area is within a ¼ mile (1,320 feet) walking distance along a walkable route (as defined in
Article 1) to ninety (90) percent of proposed dwelling units entrances or other applicable building entrances;
(2) The common areas(s) shall be located within the development to connect to each other and adjacent open spaces via a walkable route.
(b) Dimensional standards for common areas which serve single family lots.
(1) Minimum size: Ten thousand (10,000) square feet.
(2) Least dimension: One hundred (100) feet.
(c) Dimensional standards for common areas which serve multi-family, mixed-use, and commercial developments.
(1) Minimum size: Eight thousand five hundred (8,500) square feet.
(2) Least dimension: Twenty (20) feet.
(3) Connectivity: When multiple common areas are provided to meet the minimum size requirement, they must be connected via a walkable route.
(d) Development standards.
(1) Primary access and visibility. At least fifty (50) percent of the required common area perimeter shall have frontage on an approved street or public right-of-way, a vehicle access easement with pedestrian facilities, a shared use path in an easement, or be directly adjacent to a building facade on the same lot that provides visibility and a pedestrian entrance into the common area.
(2) Secondary entry points. Secondary entry points shall be a minimum of twenty (20) feet wide and contain a minimum five (5) foot wide sidewalk that connects to pedestrian facilities on an adjacent approved street, public right-of-way, vehicle access easement, or shared use path in an easement.
(3) Physical improvements. Common areas must include physical improvements and amenities including, but not limited to, walking paths, gardens, play areas, swimming pools, sports facilities, and the like to support passive and/or active uses.
(4) Canopy coverage and shading. Large tree canopy (Group A species) or other shade providing structures must cover thirty (30) percent of the required common area. Small and/or medium tree canopy (Group B and C species) may fulfil this requirement only when preexisting overhead conflicts are present or when existing tree canopy is preserved.
(5) Topography and hydrology. A minimum of fifty (50) percent of the common area shall be a generally flat and dry surface suitable for recreational use. Retention and detention basins, wetlands, floodplains and their buffers may be used to meet a portion of the common area requirement if its banks are vegetated and landscaping is provided around the perimeter in an effort to make it a visual amenity for the development and the perimeter is accessible by the provision of pedestrian facilities.
(e) Calculation and documentation.
(1) Calculation. Only the portions of common areas which meet the applicable requirements of sections 20-5(a) through 20-5(d) may be included in area and distance calculations.
(2) Preliminary development plan requirements.
(a) Common areas must be generally located and dimensioned on the plan.
(b) The provided common area square footage shall be listed in the statistical summary of pertinent site data.
(c) Documentation of walkable routes and distances may be requested by the Division of Planning. Requested documentation shall be provided as a visual exhibit at an appropriate scale.
(3) Final development plan and preliminary subdivision plan requirements.
(a) Common areas must be clearly designated and dimensioned and should appear visually distinct from non-qualifying areas.
(b) The provided common area square footage shall be listed in the statistical summary of pertinent site data.
(c) Documentation of walkable routes and distances may be requested by the Division of Planning. Requested documentation shall be provided as a visual exhibit at an appropriate scale.
(d) The requirements of 20-5(d) shall be depicted on the plan or and/or documented through notes on the plan.
