Alhance Credit Union
New Hanover County
Dear Ms Peterson
The Division of Water Quality's Stormwater Permitting Unit received a Stormwater Management Permit
Application for Alliance Credit Union on October 5, 2006 A preliminary review of the package indicates that
additional information is required to complete processing this permit application Please address the following
items
PIease specify the name of your corporation ALLIANCE CREDIT UNION is specified on the
application, but is not registered with the Department of the Secretary of State on their website,
http //www secretary state nc us/corporations/
2 Please correct inconsistencies between the application, the development plan, and the
calculations One example is the differing impervious surface areas and associated percentages
The parking and sidewalk square footages differ between the application and the development
plan Additionally, the drainage area to the pond should include the surface area of the pond The
built upon area and impervious area on the application should reflect these revisions This may
not be a complete list of inconsistencies
Please indicate the permanent pool, temporary pool, and forebay volumes on your wet detention
basin supplement sheet A copy of the supplement you submitted is included The dimensions
for each line and arc formed by the permanent pool contour must also be indicated on the plan so
that the volumes can be verified
4 Please specify the wetland species to be planted in the wet pond
Please revise the detention pond to provide for a 10-foot wide vegetative shelf Please also
ensure that the length to width ratio for the revised detention pond is 3 1
Please provide a table of elevations, areas, incremental volumes and accumulated volumes for the
overall pond and the forebay This table must show values for the pond bottom, permanent pool,
and temporary pool
Please show a trash rack with <4" openings on the outlet structure detail

Footnotes
i when using,the Division SA/DA tables, the correct SA/DA ratio for permanent pool sizing should be computed based upon the
actual impervious % and permanent pool depth. Linear interpolation should be employed to determine the correct value for non-
standard table entnes Y
Z In the 20 coastal counties, the requirement for a vegetative filter may be waived if the wet detention basin is designed to provide
90% TSS removal The NCDENR SMP manual provides design tables for both. 85% TSS removal and 90% TSS removal

Maintenance activities shall be performed as follows

1. After every significant runoff producing rainfall event, and at least monthly
a Inspect the wet detention basin system for sediment accumulation, erosion, trash accumulation,
vegetated cover, and general, condition.
b. Check and clear the orifice of any obstructions such that drawdown of the temporary pool occurs within
2 to 5 days as designed.
z
2 Repair eroded areas immediately, re -seed as necessary to maintain good vegetative cover, mow vegetative
cover to maintain a maximum height of six inches, and remove trash as needed
3. Inspect and repair the collection system (i a catch, basins, piping, swales, nprap, etc ) quarterly to maintain.

4. Remove accumulated sedmment from the wet detention basin system semi-annually or when depth is
reduced to 75% of the original design depth (see diagram below). Removed sediment shall be disposed of
in an appropriate manner and shall be handled in a manner'that will not adversely impact water quality (i e
stockpiling near a wet detention basin or stream, etc )
r
The measuring device used to determine the sediment elevation shall be such that it will give an accurate
depth reading and not readily penetrate into accumulated sediments,
,
When the permanent pool depth reads 2,75_ feet in the main pond, the sediment shall be removed.
When the permanent pool depth reads Z. 7-5' feet in the forebay, the sediment shall be removed
