structures, safety of the public, and the removal efficiency of the BMP Important mamtenance 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 10 inch (or 15 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 BMP
