Annette /Sue, Attached is a PDF of the Conceptual Stormwater Management plan for the above reference project. It is
my understanding that ECS Ltd. submitted an Individual Permit to the Army Corps of Engineers for review last week. The
attached plan is intended to address how this project will conceptually comply with the required 401 Water Quality
Certification. We are proposing to submit final design, calculations, and construction details to NCDENR for review and
approval after the Army Corps approves the Individual Permit. This approach was acceptable based on our initial
meeting onsite with Sue Homewood, John Thomas and Ashley Furniture.
The site is approximately 667 acres in total area. We are proposing two wet detention ponds to treat approximately 295
acres of new and a portion of the existing impervious areas. The ponds shown on the attached plan are sized in
accordance with the current version of the NCDENR BMP manual for 90% TSS removal efficiency with 90% impervious
coverage. The runoff within the drainage boundary from the proposed development will be conveyed to the ponds via
storm drainage piping. The ponds will be constructed upland of any wetlands or streams.
Please let me know if you have any questions or require any additional information.
