This submittal also includes information discussed with Annette Lucas. Enclosed in this submittal is the following- 1 . Construction plans and calculations for the WS/FC Zone 7 School. This project was designed by a different engineering firm and is currently constructed on Tract 2 within the Village Point development. We obtained these copies from the Village of Clemmons. 2. Construction plans and calculations for the wet detention pond that we are proposing to build as a part of the phase 2 roadway construction between Harper Road and the new WS/FC Zone 7 School. 3. Revised Overall Conceptual Stormwater Management Plan. We added additional notes clarifying the existing and proposed sections of the development. 4. Signed and notarized O&M Agreement for the "Temporary Sediment Trap BMP" that will temporally treat the runoff from the roadway over the dam until Tract 6 is developed. The runoff from the roadway over the dam will be diverted into the Tract 6 BMP when Tract 6 is developed. The existing sediment trap will be cleaned out and made operational within 30 days of this letter. Enclosed is a copy of the email correspondence. Please advise if the submittal package is incomplete or if you need additional information. If you should have any questions about the design, please do not hesitate to call for a clarification.

I wanted to confirm what we plan to submit to you as a response to your request for more information. See comment #2 on your letter dated May 13, 2011. We are constructing a wet detention basin as a part of project to treat Village Point Drive and Harper Road (the impervious being constructed as a part of this project) to the maximum extent possible. The pond was designed in accordance with the NCDENR BMP manual and we are completing the supplement forms and worksheets now. Clemmons has reviewed the BMP and we expect comments any day now. We are not following the NCDOT linear guidelines because we are building standard BMP's within each lot to treat the roadways and future developed lots as they are built-out. Can you confirm this is what you were looking for? See comment #3 on your letter dated May 13, 2011. Michael Brame with ECS indicated that you had trouble following the drainage areas on the SWM master plan. We will clean that up. Not sure if this was the basis of the comment you made. I assume you couldn't tell how the "driveway" for tract 6 was being treated. We had planned for the "driveway" into Tract 6 to be treated with a BMP constructed with the future development of Tract 6. We can place a bolder note on the SWM master plan that makes this obvious for Tract 6. Will that be sufficient? I will be out of the office for the remaining of the afternoon. Thanks. Kelway L.

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 temporary sediment basin system does not incorporate a vegetated filter at the outlet. Important maintenance procedures: ? No portion of the temporary sediment basin 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 temporary sediment 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. After the temporary sediment basin 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.
