Wetland name or number A SLOPE WETLANDS Hydrologic Functions - Indicators that the site functions to reduce flooding and stream erosion S 4.0. Does the site have the potential to reduce flooding and stream erosion? S 4.1.Characteristics of plants that reduce the velocity of surface flows during storms: Choose the points appropriate for the description that best fits conditions in the wetland.Stems of plants should be thick enough(usually>1/8 in), or dense enough, to remain erect during surface flows. 0 ❑Dense, uncut, rigid plants cover>90%of the area of the wetland points=1 ❑AII other conditions points=0 Rating of Site Potential If score is:_1=M ✓ 0=L Record the rating on the first page S 5.0.
