DIVISION OF WATER QUALITY - 401 WET DETENTION BASIN WORKSHEET
DWO Stormwater Management Plan Review
A complete stormwater management plan submittal includes a wet detention basin worksheet for each basin,
design calculations, plans and specifications showing all basin and outlet structure details, and a fully executed
operation and maintenance agreement. An incomplete submittal package will result'in a request for additional
information and will substantially delay final review and approval of the project.
I. PROJECT INFORMATION please complete the following information):

II. REQUIRED ITEMS CHECKLIST
The following checklist outlines design requirements per -the Stormwater Best Management Practices manual
(N.C. Department of Environmenti, Health and Natural Resources, November 1995) and Administrative Code

been met and supporting documentation is attached: If a requirement has not been met, attach an ezplaturtion of
why.
