DV STD & SPEC 3.12 DIVERSION Practice Description A channel constructed across a slope with a supporting earthen ridge on the lower side, to reduce slope length and to intercept and divert stormwater runoff to stabilized outlets at non-erosive velocities. Conditions Where Practice Applies 1. Where runoff from areas of higher elevation may damage property, cause erosion, or interfere with the establishment of vegetation on lower areas. 2. Where surface and/or shallow subsurface flow is damaging sloping upland. 3. Where the slope length needs to be reduced to minimize soil loss. Construction Specifications 1. Ridge: The supporting ridge cross-sectioned shall meet the following criteria: a. The side slopes shall be no steeper than 2:1. b. The width at the design water elevation shall be a minimum of 4 feet. c. The minimum freeboard shall be 0.3 foot. d. The design shall include a 10 percent settlement factor. 2. Outlet: Diversions shall have adequate outlets which will convey concentrated runoff without erosion. Acceptable outlets include STORMWATER CONVEYANCE CHANNEL (Std. & Spec. 3.17); LEVEL SPREADER (Std. & Spec. 3.21); OUTLET PROTECTION (Std. & Spec. 3.18); and PAVED FLUME (Std. & Spec. 3.16). 3.
