1. DIIFUSE FLOW PLAN:
a. To meet the diffuse flow requirements, a 50-foot minimum width of the
filter strip is required. Unless the vegetation downstream of each proposed
30-foot grass filter strip is dense, you will need to revise the level spreader
length calculations. The filter strip width is measured from the level
spreader lip to the top of stream bank. The required filter strip length per
cfs of flow shall be calculated as a weighted average of the lengths
required for each vegetation type and/or density. Please refer to Section
13.3.4 of the NCDWQ BMP Manual for further guidance.
b. Please provide photos of the vegetation within the area below the 30-foot
filter strip.
