There are two wetlands and one inlet that are at immediate risk and that are receiving our attention at this time. In addition there are some small wetlands on private property that do not appear to need out attention for now. If anyone knows of the deterioration of any wetland in our community please let us know. Those that we have identified to be at risk are:
- The inlet between the Loch Lomond Marina and Beach Drive. This is not strictly a “wetland” but it “feeds” the neighboring wetland and is deteriorating rapidly, so it is of concern to our neighborhood.
- The wetland across Beach Drive on the east side of the inlet.
- The wetland between the quarry/brickyard and Pt. San Pedro Road.
There are several reasons, among them:
- A subsidence of a section of the levee has interrupted the tidal flow.
- Silt is being washed down of the hillside into the inlet.
- Silt is brought down by the Sacramento River into the Bay and under some circumstances can be carried into the inlet.
We need expert engineering advice to proportion these factors and determine the best remedial action.
We raised funds and coordinated the project to repair the flap-gate into the Beach Drive wetland. This included obtaining $5,000 from the discretionary fund of our Marin County supervisor, Susan Adams. The total cost was approximately $25,000. This will help reduce sediment entering the wetland during the next winter storm.
We have encouraged the Quarry to be concerned about their wetland. They appointed a consultant to review the health of their wetland although, as yet, we have not seen this report.
We are currrently investigating what is the cause of the silting of the Inlet and how to repair and restore it. As part of this effort, we are soliciting the assistance of the County as well as others.
