RE: NWP 29 Application for Hanover Lakes Subdivision; New Hanover County, NC
Additional Information
Action ID# SAW-2008-03032
Dear Emily:
Thank you for your letter dated August 14, 2009 in which you request additional
information regarding the Hanover Lakes Subdivision NWP application. Below is a response to
each of your comments.
Please justify your need to impact 0.20 acre of bottomland hardwood forest for lot fill (wetland
impact #2) and demonstrate how you have avoided and minimized to the maximum extent
practicable. This office recommends that all lots be designed so that all jurisdictional wetlands
and waters are located within open space.
The applicant has revised the site plan to reduce wetland impacts. Impact #2 has been revised
and wetland impacts at this location have been reduced to 0.024 acre. Total wetland impacts
have been reduced to 0.135 acre. Enclosed are revised maps and pages 3, 5, and 7 of a revised
PCN form (pages 3, 5, and 7) that reflect these changes.
General Condition #20 of the Nationwide Permits states that a minimum of 1:1 mitigation is
required for impacts exceeding 0.10 acre.
To mitigate for 0.135 acre of wetland impacts, the applicant proposes to preserve 14.96 acres of
wetlands on site (see enclosed map). This would be a 111:1 mitigation to impact ratio. The
applicant plans to preserve these wetlands by incorporating the Corps' standard preservation
language into the subdivision's restrictive covenants. Once we have received correspondence
from you that this course of mitigation is acceptable, the applicant will prepare draft preservation
map and restrictive covenants.

you for your assistance with this project.
