specifications") as attached and/or on file with and approved by the Division of Energy, Mineral and
Land Resources (the "Division" or "DEMLR"). The project shall be constructed, operated and
maintained in accordance with these approved plans and specifications. The approved plans and
specifications are incorporated by reference and are enforceable part of this permit.
This permit shall be effective from the date of issuance until August 8, 2029 and shall be subject to

I. DESIGN STANDARDS
1. This permit is effective only with respect to the nature and volume of stormwater described in
the application and other supporting data.
2. This stormwater system has been approved for the management of stormwater runoff as
described in Sections 1.7 and 1.8 of this permit. The stormwater controls have been designed
to handle the runoff from a total of 394,165 square feet of impervious area. The wet pond will
treat 387,915 sf and the infiltration trench will treat 6,250 sf.
3. A 50' wide vegetative buffer must be provided adjacent impounded structures, streams, rivers
and tidal waters.
4. The tract will be limited to the amount of built -upon area indicated on page 3 of this permit, and
per approved plans. The built -upon area for the future development is limited to 240,185 sf to
drain to the pond, which is included in the 387,915sf total impervious to drain to the pond.
Page 1 of 5

Post -Construction Stormwater Management

5. 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.
6. The runoff from all built -upon area within the permitted drainage areas of this project must be
directed into the permitted stormwater control system.

Wet Detention Basin Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
The wet detention basin system is defined as the wet detention basin,
pretreatment including forebays and the vegetated filter if one is provided.
This system (check one):
❑ does ® does not incorporate a vegetated filter at the outlet.
This system (check one):
❑ does ® does not incorporate pretreatment other than a forebay.
Important maintenance procedures:
— Immediately after the wet detention basin is established, the plants on the
vegetated shelf and perimeter of the basin should be watered twice weekly if
needed, until the plants become established (commonly six weeks).
— No portion of the wet detention pond should be fertilized after the first initial
fertilization that is required to establish the plants on the vegetated shelf.
Stable groundcover should be maintained in the drainage area to reduce the
sediment load to the wet detention basin.
If the basin must be drained for an emergency or to perform maintenance, the
flushing of sediment through the emergency drain should be minimized to the
maximum extent practical.
Once a year, a dam safety expert should inspect the embankment.
After the wet detention pond is established, it should be inspected once a month and
within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a
Coastal County). Records of operation and maintenance should be kept in a known set
location and must be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.
