5 Structure Details: A. South Richford Road Local ID- srich010 Label- B21 (has a bridge label but it is a culvert) 72 inch diameter, round steel corrugated culvert On tributary of Alder Brook Undersized, bankfull width is at least 12 ft - Significant scour pool at culvert outlet. Culvert has concrete header, footer, and poured concrete bottom. - At least a drop from culvert outlet to water surface. In lower flow, this drop would be more significant. Steep stream elevation change between inlet and outlet. Very long structure ft. Figure 2. Culvert outlet Page 5 of 22

Combs Road Culvert Local ID- comb020 Label- B22 (has a bridge label but it is a culvert) inch diameter, round steel corrugated culvert (culvert inventory from 2014 has 60 inches but out in the field today it looked like 48 inches) 25 ft. in length On tributary of Alder Brook Undersized, bankfull width is at least 10 ft (I believe this is from hydraulic curves, not field measured) Culvert outlet is rusted out on bottom Moderate stream elevation change between inlet and outlet.
