IV. DEED RESTRICTIONS AND PROTECTIVE COVENANTS
The following italicized deed restrictions and protective covenants are required to be recorded for all
subdivisions, outparcels and future development prior to the sale of any lot. If lot sizes vary significantly, a
table listing each lot number, size and the allowable -built -upon area for each lot must be provided as an
attachment.

4. Built -upon area in excess of the permitted amount requires a state stormwater management permit modification prior to
construction.
5. All permitted runoff from outparcels or future development shall be directed into the permitted storm water control
system. These connections to the stormwater control system shall be performed in a manner that maintains the
integrity and performance of the system as permitted.
By youi signature below, you certify that the recorded deed restrictions and protective covenants for this project
shall include all the applicable items required above, that the covenants will be binding on all parties and

Forebay Volume 613 cu. ft. (approximately 20% of total volume)
Other parameters

Form SWU-102 Rev 3.99 Pagel of 4

Footnotes:
1 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 entries.
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 NCDI NR BMP manual provides design tables for both 85% TSS removal and 90% TSS removal.
II. REQUIRED ITEMS CHECKLIST
The following checklist outlines design requirements per the Stormwater Best Management Practices Manual
(N.C. Department of Environment, Health and Natural Resources, February 1999) and Administrative Code
Section: 15 A NCAC 2H .1008.
Initial in the space provided to indicate the following design requirements have been met and supporting
documcn:tation is attached. If the applicant has designated an agent in the Stormwater Management Permit
Application Form, the agent may initial below. If a requirement has not been met, attach justification.
Applicants Initials
a. The permanent pool depth is between 3 and 6 feet (required,minimum of 3 feet).
.e. b. The forebay volume is approximately equal to 20°l0 of the basin volume.
Ot12 . c. The temporary pool controls runoff from the design -storm event.
,R . d.-The temporary pool draws down in 2 to 5 days.
e: _ If required, a 30-foot vegetative filter is provided at the outlet.(include non -erosive flow
calculations)
f. The basin length to width ratio is greater than 3:1.
19Z, g.. ' The basin side slopes above the permanent pool are no steeper than 3: 1.
h: A submerged and vegetated perimeter shelf with a slope of 6:4 or less (show detail).
i. Vegetative cover above the permanent pool -elevation is specified.
j. A trash rack or similar device is provided for both tlie-overflow and orifice.
k. A recorded drainage easement is provided for each basin including access to nearest right -
of -way' -
AL -_ 1. if the basin is used for sediment and erosion control during construction, clean out of the
basin is specified prior to use as a wet detention basin.
r
in. A mechanism is specified which will drain the basin for maintenance or an emergency.

III. WET DETENTION BASIN OPERATION AND MAINTENANCE AGREEMENT
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) O.does does not incorporate a vegetated filter at the outlet. -
This system (check one) 0 does does not incorporate pretreatment other than a forebay.

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.
I
b. Check and clear the orifice 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 collections stem(i.e. catch basins, piping, swales, ri ra , etc.) quarterly to
maintain proper functioning.
I
I
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.).
I .4
- _ The .measuring device used to de"terzriine the.secliment 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. 5.i Z5 feet in the main pond, the sediment shall be -removed. _
When the permanent pool depth reads s: Z ` - feet in the forebay, the sediment shall be -removed.

5. Remove cattails and other indigenous wetland plants when they cover 50% of the basin surface. These
plants shall be encouraged to grow along the vegetated shelf and forebay berm.
6. If the basin must be drained for an emergency or to perform maintenance, the flushing of sediment
through the emergency drain shall be minimized to the maximum extent practical.
