A mechanism is specified which will, drain the basin for maintenance or an emergency. u 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) 0 does oincorporate a vegetated filter at the outlet This system (check one) 0 does :i�no_tt incorporate pretreatment other than a forebay. Forrn SwII-102 Rev 3.99 Page 2 of 4 Maintenance activities shall be performed as follows: 1. After every significant runoff producing rainfall event and at Ieast 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. 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 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-wetdetention basin or stream, etc.). .

SHALLO'ITE, NORTH CAROLINA , 28459 Telephone (910) 754-6324 Facsimile (910) 754-2121 117 Pine Street Post Office Box 627 Narrative/Project Description, (Brunswick Plantation - North Addition): The subject project is located in southeast Brunswick County. The subject project Brunswick Plantation - North Addition is just north of the existing Brunswick Plantation. Brunswick Plantation - North Addition is a residential project and consists of single family lots, two multi -family developments, 8 holes of golf, and an amenity center. The single family developments are divided into Phases 1-3, and the multi-famly developments are Phases 4 & 5. Development of the North Addition will be accompanied with curb and guttered roadways with frame and grate inlets and piping. Stormwater Ponds have been engineered for treatment. The overall flow of the project is from south to north and into the Caw Caw Canal. Upstream ponds are connected in series before entering an engineered stormwater pond in most cases. Stormwater Pond # 1 consists of two large golf course ponds. The treatment pond is divided by two golf holes. The two large golf course ponds are equalized by 2 - 36" culverts. Six (6) upstream ponds are connected in series and enter ,a forebay of Stormwater Pond # 1. Each of r these upstream ponds will act as a forebay. Stomwater is Collected and piped into the upstream ponds. Each of these upstream ponds is routed into a forebay of Stormwater Pond # 1. Stormwater Pond # 1 is designed to treat the drainage areas for each of these upstream ponds as well as for the drainage area of Stormwater Pond # 1. Stormwater Pond # l is also designed for future Multi -Family development (Considered Off -Site). Stormwater Pond #1 outlets into the Caw Caw Canal. Stormwater Pond #2 is also a two pond Stormwater Pond with two forebays. Single family lots, roadway areas, and golf course areas are treated in Stormwater Pond #2. Neither, Multi -Family flows or off -site flow enters Stormwater Pond _#2. Stormwater Pond #2 outlets into the Caw Caw Canal. Stormwater Pond #3 is on the golf course and treats single family lots, roadways, golf course, and future Multi -Family development (Considered Off -Site). Stormwater Pond #3 outlets into a piping system that is proposed through the project. In the pre -development condition there is a ditch that runs through the project carrying off -site water into the Caw Caw Canal. This ditch will now be piped through the project and into the Caw Caw Canal. There is no untreated water from the project entering this piping system. Stormwater Pond #3 outlets into this piping system. A future Stormwater Pond that will be engineered to treat a future Multi-li amilly development will also enter this Off -Site piping system. Another feature about this piping system is that it runs through the forebay berm of Stormwater Pond #2. The pipe will be well below the top of the forebay berm and have no adverse effects on Stormwater Pond #2. Headwater calculations show that using one pipe to convey this water will cause water to back-up in the pipe. Therefore, it is proposed to construct a second 48" pipe to reduce the tailwater conditions. ` HOUSTON and ASSOCIATES, P.A.

The subject project Brunswick Plantation - North Addition is just north of the existing Brunswick Plantation. Brunswick Plantation - North Addition is an Overall Low Density project and consists of single family subdivisions, one multi -family development, 8 holes of golf, and an amenity center. The single family developments are divided into Sections 1-5, and the multi-famly development is Section 6. Each section of the North Addition will be submitted for its own stormwater permit. The Overall Stormwater Plan will be updated and submitted with each section submittal. Development of the North Addition will be accompanied with curb and guttered roadways with frame and grate inlets and piping. A combination of Curb Outlet Swales and Stormwater Ponds will be engineered for treatment. The overall flow of the project is from south to north and into the Caw Caw Canal. There are existing perimeter ditches at the property boundaries that convey stormwater to the Caw Caw Canal. Upstream ponds will connectoo in series before entering an engineered stormwater pond in some cases. This submittal is for an Overall Low Density Stormwater Permit for Brunswick Plantation - North Addition. 1i k State of North Carolina Department Of Environs-nent and Natural Resources Wilmington Regional Office Division of Land Resources Land Quality Section Michael F.

If I were to issue a permit without the supplement, technically, you could build the project as shown on the overall plan without further permits from us. However, what I can do is put specific conditions in the permit which acknowledge that a curb outlet system is proposed, but that nothing can be built (not even the main access road) until the detailed plans and curb outlet supplement are submitted and approved. Linda Jason Clark wrote: Linda. We are not showing any curb outlet swales on the Overall Plan. Curb outlet swales and Stormwater Ponds will be used with the design of each Section. This plan is to get a Low Density Overall Stormwater Permit. We were trying go do this development like we have been doing Ocean Ridge Plantation (An Overall Plan & Overall Low Density Permit, and each Section has its own individual Stormwater Permit). I can submit to you a Curb Outlet Supplement, but page 2 would be blank. Section 1 and maybe all of the single family sections will be submitted soon for their own Stormwater Permit with stormwater ponds and curb outlet swales and all necessary supplements. I guess I'm not sure why a curb outlet swale is required for an Overall. how Density Permit.

This submittal replaces the submittal you currently have for an Overall Stormwater Permit SW8 031026.

The Plans enclosed propose that all stormwater from the project be treated in engineered stormwater ponds. Curb outlet swales are not being used for this project. Since all stormwater is being treated in ponds there is no need for an overall low density permit.
