We require a signed and notarized Operation and Maintenance Agreement for the Level Spreader - Vegetated Filter Strips
(LS -VFS). A sample of one that applies to a LS -VFS is available at: http: / /portal.ncdenr.org /web /wq /ws /su /bmp -ch8.
But we can accept other formats as well as long as they address the important maintenance issues. Please let me know
if you have questions.

Annette,
Troy asked me to send you an email to double check on what you need in order to issue the permit. The City does have a
"Declaration of Maintenance Covenant and Grant of Protection Easements for Stormwater Control Facilities" but it is my
understanding that this does not typically get recorded until the plat is being recorded. We are not at that step yet. We do
have infrastructure plan approval and are getting ready to submit the grading permit for review. Please advise on what
you need to complete the permits.
Thanks,
John

Permit Number :.
(to be provided by DWQ)
Drainage Area Number:
Filter Strip, Restored Riparian Buffer and Level Spreader
Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. 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.
Important maintenance procedures:
— Immediately after the filter strip is established, any newly planted vegetation
will be watered twice weekly if needed until the plants become established
(commonly six weeks).
— Once a year, the filter strip will be reseeded to maintain a dense growth of
vegetation
— Stable groundcover will be maintained in the drainage area to reduce the
sediment load to the vegetation.
— Two to three times a year, grass filter strips will be mowed and the clippings
harvested to promote the growth of thick vegetation with optimum pollutant
removal efficiency. Turf grass should not be cut shorter than 3 to 5 inches and
may be allowed to grow as tall as 12 inches depending on aesthetic requirements
(NIPC,1993). Forested filter strips do not require this type of maintenance.
— Once a year, the soil will be aerated if necessary.
— Once a year, soil pH will be tested and lime will be added if necessary.
After the filter strip is established, it will be inspected quarterly and within 24 hours
after every storm event greater than 1.0 inch (or 1.5 inches if in a Coastal County).
Records of operation and maintenance will be kept in a known set location and will be
available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.
