The table belowhigh if it is greater than 5. After evaluation of these characteristics as presented in the project’s drainage area map, hydrology and hydraulic studies, construction plans, geotechnical2 acres. The average outfall slope is mild if it is equal to or less than 0.03, and steep if it is greater than 0.03. The soil erosion index is low if it is less than or equal to 5 andin cut, road widening, and maintenance/safety. The disturbed area classes are less than or equal to 1 acre, greater than 1 acre to less than 2 acres, and equal to or greater thandisturbed acreage, the average slope about the outfall, and the soil erosion index 0-10, 10 being the most erodible soil.
