If the applicant has designated an agent in the Stormwater Management Permit Application Form, the agent may initial below. If a requirement has not been met, attach justification. Applicants Initials a. Curb outlets direct flow to a swale or vegetated area. b. Swales or vegetated areas receiving curb outlet flow are designed to carry, at a minimum, the peak flow from the 10-year storm. c. Flow velocity is non -erosive for peak flow from the 10-year storm event. d. Longitudinal slope of the swale or vegetated area does not exceed 5%. e. Side slopes of the swale or vegetated area are no steeper than 5:1 (horizontal to vertical). f. Length of swale or vegetated area is 2� 100 feet. g. The system takes into account the run-off at ultimate built -out potential from all surfaces draining to the system (delineate drainage area for each swale). h. Swales are located in recorded drainage easements. r' i. Grass type(s) for permanent vegetative cover specified on detail J. Swale detail provided on plans. Form SWU-105 Version 3.99 Page 1 of 3 III.

CURB OUTLET SYSTEM MAINTENANCE REQUIREMENTS l . Mowing will be accomplished as needed according to the season. Grass height will not exceed six inches at any time. 2. Swales will be inspected monthly or after every runoff producing rainfall event for sediment build-up, erosion, and trash accumulation. 3. Accumulated sediment and trash will be removed as necessary. Swales will be reseeded or sodded following sediment removal. 4. Eroded areas of the swales will be repaired and reseeded. Swales will be revegetated as needed and in a timely manner based on the monthly inspections. 5. Catch basins, curb cuts, velocity reduction devices, and piping will be inspected monthly or after every significant runoff producing rainfall event. Trash and debris will be cleared away from grates, curb cuts, velocity reduction devices and piping. 6. Swales will not be altered, piped, or filled in without approval from NCDENR Division of Water Quality. acknowledge and agree by my signature below that I am responsible for the performance of the six maintenance procedures listed above.
