commonly six weeks).
- Once a year, the filter strip will be reseeded to maintain a dense growth of
'aegetation
- Stable groundcover will be maintained in the drainage area to reduce the
?:ediment load to the vegetation.
- Two to three times a year, grass filter strips will be mowed and the clippings
'iarvested 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
:nay 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.
0.ire 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 stonn event greater than 1.0 inch (or 1.5 inches if in a Coastal County).
Record; of operation and maintenance will be kept in a known set location and will be
