Landscape design
A. Plant selection for multi-family, commercial, or mixed-use development.
1) No tree, shrub or plant shall be proposed that has been identified as an invasive species by the Rhode Island Invasive Species Council.
2) Landscaping shall be designed to remain functional and attractive during all seasons through a thoughtful selection of deciduous, evergreen, berrying, and flowering plant varieties including meadows of perennial and annual plants.
3) Plant varieties shall be selected for resistance to drought, moisture, salt, urban conditions, or insects and other pests depending on the location of landscaping and the specific stressors anticipated for different areas of the site. Plants shall be selected, with preference to plant species native to Rhode Island in order to maximize biodiversity and the landscaping's contribution to Jamestown's ecosystem, so that landscaping can be maintained with minimal care and the need for watering, pesticides or fertilizers can be minimized or eliminated.
4) The use of turf shall be minimized, but where it is used, turf should not be planted in strips less than six feet wide in any direction. Lawn seed mixes shall be drought resistant. To achieve a high level of drought tolerance, lawn mixes may include, but shall not be limited to, a predominance of fine fescues.
B. General to zones CW, CL, CD and P.
1) Landscaping shall be used as part of a site-wide stormwater management strategy to the maximum extent practicable. Vegetated management practices for stormwater runoff may include, but are not limited to:
a) Rain gardens and/or bioretention facilities
b) Grassed and/or vegetated swales
c) Extensive or intensive green rooftops
d) Tree trenches and/or individual tree box filters
2) Cisterns and rain barrels are encouraged for use in landscape watering.
3) The restoration or rehabilitation of an existing building eligible for inclusion on a state, local or national historic register to National Park Service Historic standards or any local historic district standards shall not require the provision of drainage infrastructure in addition to what already exists.
