2 This stormwater system has been approved for the management of stormwater
runoff as described in Section 16 on page 3 of this permit Pond #1 has been
designed to handle the runoff from 169,651 square feet of impervious area
Pond #2 has been designed to handle the runoff from 378,007 square feet of
impervious area
3 The tract will be limited to the amount of built -upon area indicated on page 3 of
this permit, and per approved plans There is no additional impervious surface
available for future development in this permit
4 All stormwater collection and treatment systems must be located in either
dedicated common areas or recorded easements The final plats for the project
will be recorded showing all such required easements, in accordance with the
approved plans
5 The runoff from all built -upon area within the permitted drainage area of this
project must be directed into the permitted stormwater control system

actual imperious % and permanent pool depth Linear interpolation should be employed to determine the correct value for non-
standard table entries
In the 20 coastal counties, the requirement for a vegetative filter may be uaived if the wet detention basin is designed to provide
90% TSS removal The NCDENR BMF manual provides design tables for both 85% TSS removal and 9051r, TSS removal

After every significant runoff producing rainfall event and at least monthly
a inspect the wet detention basin system for sediment accumulation, erosion, trash accumulation,

This system (check one) 0 does ddoes not incorporate pretreatment other than a forebay
Form S" L -102 Rev 3 99 Pape 2 of 4

Maintenance activities shall be performed as follows
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 onfice of any obstructions such that drawdown of the temporary pool occurs
within 2 to 5 days as designed
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 proper functioning
4 Remove accumulated sediment 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 )
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 feet in the main pond, the sediment shall be removed
When the permanent pool depth reads �' 3 feet in the forebay, the sediment shall be removed

this permit, and per approved plans There is no additional impervious surface
avaiable for future development in this permit
4 All stormwater collection and treatment systems must be located in either
dedicated common areas or recorded easements The final plats for the project
will be recorded showing all such required easements, in accordance with the
approved plans
5 The runoff from all built -upon area within the permitted drainage area of this
project must be directed into the permitted stormwater control system
