Dear Mr. Williamson:
The Wilmington Regional Office received a complete Stormwater Management Permit
Application for The Pearl on December 21, 2007. Staff review of the plans and specifications
has determined that the project, as proposed, will comply with the Stormwater Regulations set

permit that may be required.
The Future High Density area associated with the Conference Center Shown on sheet 10 of 22
will require a permit modification. Prior to construction in this area the permitee shall have
received approval for revised plans, specifications and calcutions.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have

LOW DENSITY SUPPLEMENT
This form may be photocopied for use as an original
A low density project is one that meets the appropriate criteria for built upon area and transports stormwater
runoff primarily through vegetated conveyances. Low density projects should not have a discrete stormwater
collection system as defined by 15A NCAC 2H .1002(18). Low density requirements and density factors can
be found in 15A NCAC2H .1005 through .1007.

• If lot sizes are not uniform, attach a table indicating the number of lots, lot sizes and allowable built upon
area for each lot. The attachment must include the project name, phase,page numbers and provide area
subtotals and totals.
II. BUILT UPON AREA
See the Stormwater Management Permit Application for specific language that must be recorded in the deed
restrictions for all subdivisions.
For uniform lot sizes, complete the following calculation in the space provided below where:
• SA Site Area—the total project area above Mean High Water. Wetlands may be excluded when the
development results in high density pockets.

• B UA/Lot—the computed allowable built upon area for each lot including driveways and impervious
surfaces located between the front line and the edge of pavement.

Rhonda and David,
In looking at both the Villages and the Maintenance areas we found the impervious
percentage to be close to 45%. I am not sure how you wanted us to do the numbers, but
I took overall drainage area without wetlands or surrounding golf holes. Ifeel the way
these areas were set up with a good amount of sheet flow that they still should be
considered Low Density and not Pockets of High.
We did pull out the areas we felt would be considered pockets ofhigh and labeled them
for future permitting.
Please let me know ifyou need additional information.
Thank you,
