I work for a local government in Puget Sound, WA. We have numerous stormwater outfall pipes that, at one time, discharged to the edge of a marine bluff (the marine bluff could be anywhere from 2 ft to 50 feet high). Over time, the bluff has eroded into Puget Sound, but the pipe now remains suspended over the "new" beach. In some cases, the pipe is now discharges to the top of a slope - in either case it's not good.
Our challenge is to replace the existing outfall with one friendly to fish and other wildlife and resistant to further erosion. Having said that, all the marine bluffs will continue to erode no matter what we do. But, we need to do something.
Splash pads on beach and gabion baskets on beach as an outfall may help disspate energy, but have proven to give the state and federal regulators heartache.
Any suggestions?
