ROAD EROSION PLAN
PROBABLE HYDROLOGIC CONSEQUENCE
The road system has been broken down into seven segments,
A through G, and each segment has been divided into stations.
The lowest point on a segment is 0+00 with station numbers
increasing uphill.
In this manner each culvert is identified. It is our pro-
posal that water quality samples and flow rates be taken in the
spring and during the summer rainfall events (on an opportune
basis) to obtain actual sediment loads. (Several samples
were taken in the spring and fall of 1982. )
Identify differences in drainages above culverts to
dissimulate disturbed areas (Cuts and fills and percent of
native or disturbed area) .
At the completion of the 1983 spring runoff period, an
updated probable hydrologic consequence report will be
submitted.
