Document Description
The project proposes a rehabilitation to eliminate the ponding and reinstate positive drainage flow away from the properties. A key component of this project is to install an 8-12 inch outfall with a flap gate to a drainage ditch, which empties to Alamo Creek, immediately to the North of the Putah South Canal. The proposed project is only intended to improve drainage issues from routine storm events and will have no adverse impact during larger storm events. The drainage flows from the property are estimated to be 0.3 and 0.4 cubic feet per second for a 10 year and 25 year event, respectively. The velocity through an 8" pipe for the higher flow is approximately 1 ft/sec. The pipe will discharge onto existing rock slope protection. The flap gate will only allow the pipe to discharge when there is capacity in the channel.
