Place fill directly over a culvert higher than the road approach to prevent surface road runoff from draining onto the crossing structure and into the stream. Figure C-2. Diversion ditch. Figure C-3. Install culverts so there is no change in the stream bottom elevation. Figure C- 4. Installation of culverts. Figure C-5a. Use riprap around the inlet of culverts. Figure C-5b. Use geotextile filter fabric for permanent installations. Figure C-6. Typical road designs form drainage and stability. Figure C-7. Cross-drain culvert. Figure C-8. Open-top log culvert. Figure C-9. Broad-based dip. Figure C-10. Water bar. Figure C-11a. Straw bale fencing to slow runoff and trap sediment for sheet flow and channelized flow. Figure C-11b. Silt fencing to slow runoff and trap sediment for sheet flow, not channelized flow. Figure C-11c. A sediment trap to slow runoff and trap sediment for channelized flow. Table of Contents |
