Stream rehab down in Long Beach
November 2, 2009 § Leave a comment
Here’s a link to a project I’m working on, a rehabilitation of the artificial stream at the El Dorado Nature Center. Sharon Gates with the City of Long Beach is maintaining the project blog to keep the faithful nature center visitors up-do-date on the goings-on in the stream – the area being fenced off for public safety during the construction. Check out the progress!
The project will be using soil bioengineering techniques like willow postings, willow wattles, etc to stabilize some of the banks that have been subject to erosion over the years. Small areas will use rip rap or logs to shore up the banks where there’s a lot of foot traffic up to the edge – we want to keep this to a minimum and emphasize the ability of willow and other native riparian plants to hold a waterway’s banks. Huge quantities of the invasive Brazilian Pepper Tree have been removed, allowing in sunlight which will help the willow take root.
A lot of folks don’t realize the stream is artificial. The historical condition of the Nature Center area was likely a periodically inundated alkali meadow or fringe area of the wetlands that today are concentrated around Los Cerritos. Today’s Nature Center provides habitat for lots of birds, turtles and some mammals (including a coyote, I have heard).
My role in the project is pretty small – Restoration Design Group has me doing some construction administration, answering questions about design intent for the City and contractors, Bubalo Construction, who are implementing the project as a design-build.
