Winfall Landing Subdivision
High Density Project
fiertford County
Fe rzd ,arts
The Washington Regional Office received a completed Stormwater Application for the subject project on July
30, 2007. Staff review of the plans and specifications has determined that the project, as proposed, will comply with
the Stormwater Regulations set forth in Title 15A NCAC 2H.1000. We are forwarding Permit No. SW7070728 dated
October 1, 2007 to Winfall Developers Inc. for a wet detention pond to serve the Winfall Landing Subdivision,
located at the terminus of Major Street off Winfall Blvd. (SR 37), Winfall, NC.
This permit shall be effective from the date of issuance until October 1, 2017 and shall be subject to the
conditions and limitations as specified therein. Please pay special attention to the Operation and Maintenance
requirements in this permit. Failure to establish an adequate system for operation and maintenance of the stormwater
management system will result in future compliance problems. The issuance of this permit does not resolve any
previous violations of the stormwater rules for construction without a permit.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the right to
request an adjudicatory hearing upon written request within thirty (30) days following receipt of this permit. This
request must be in the form of a written petition, conforming to Chapter 150B of the North Carolina General Statutes,
and filed with the Office of Administrative Hearings, 6714 Mail Service Center, Raleigh, NC 27699-6714. Unless such
demands are made this permit shall be final and binding.
If you have any questions, or need additional information concerning this matter, please contact Ernest Odei-
Larbi or me at [phone].

_-Maintenanc'e activities shall be perforated as follows:
1. After every significant runoff producing rainfall event and at least monthly:
a. Inspect the wet detention basin system for sediment accumulatior, 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.
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.e. catch basins, piping, swales, riprap, etc.) quarterly to
maintain proper functioning.
4. Remove accumulated sediment from the wet detention basin systern 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 penewate into accumulated sediments.
When the permanent pool depth reads -S feet in the main pond, the sediment shall be removed.
When the permanent pool depth reads S• .2,5 feet in the forebay, the sediment shall be removed.
