Re: Colonial Ridge - TRC Plan Review Comments
• Section 67-3 of the Zoning Ordinance requires that a tree inventory be completed
and that regulated and significant trees be preserved to the greatest extent
practical and incorporated into required landscaping. Unsuitable reasons for
clearing include "such factors as more parking than the minimum specified in
Section 80 is desired or that non-selective clearing by bulldozer is less expensive
than selective clearing by chainsaw."
• Throughout the site, existing trees should be incorporated into landscape islands
and required landscape areas. Trees located within areas to be dedicated for
stormwater improvements should be worked into the stormwater plan by
incorporating Low Impact Development techniques. Trees located in open space
areas (specifically the large open space and wetland area on the far east of the
property) should be preserved.
• It is indicated on the plan that 2 significant trees will be removed from the right of
way and mitigated, however, there is no indication of any trees that will be
removed for any other site improvements (including development of the
individual lots). These trees must also be accounted for.
• To limit the need for water consumption for landscaping purposes, it is
recommended that native landscape materials be incorporated throughout the site
design. Water reuse is encouraged on home sites with the incorporation of
devices such as rain water catchment systems - rain barrels or cisterns.
• The proposed development drains to the Atlantic Intracoastal Waterway through
creeks that have been designated as SA waters for shellfishing. To protect water
quality, it is recommended that the use of Low Impact Development (LID)
techniques be utilized in coordination with required stormwater management
techniques. LID techniques could include: a constricted wetland, bioretention
areas (rain gardens), pervious pavement, and vegetative buffer strips. It is
recommended that the engineer refer to the City-County Joint Low Impact
Development Manual for information about LID techniques.
• Recommend minimizing the amount of impervious surfaces for roadways and
parking and incorporating the use of pervious paving options on low flow traffic
areas, driveways, and sidewalks.
• Recommend limiting grading only to locations for driveways and streets.
• Preliminary maps show that wetlands are present on the property. All wetlands
must be delineated and permitted through the Corps.
