From that point there would be a 4 to 1 slope, which would catch at or before the property line to the open space. From an erosion control standpoint, immediately after this is overlotted, the top soil that was stripped from this site would be placed on these slopes and would be seeded and mulched. In addition, along the boundary of the property there would either be erosion control bales or silt fences. There would also be a swale along that with silt fences, which would carry the runoff to the existing detention facilities.

The silt fences are primarily put in place until vegetation is established on the slope. The silt fence will be most effective immediately, if we get a storm prior to when the seeding begins to grow on the slope. The silt fences are not important within five (5) years after. Lathrop: If you're going to re-seed that slope after overlotting, what about the area up on the top going north? Is that going to be re-seeded?
