Inspector

Phil Stevens, Executive Director of the Urban Creeks Council writes:

"UCC has met with 78 Ross Valley homeowners to date, exceeding the number expected (50) under the contract. A large majority of those visited so far ranked the severity of the issues they face in the highest category. We've been impressed with how knowledgeable Marin residents are in general about issues with their creeks. They've given us a warm welcome and we have already lined up several possible projects that we hope will go to construction in 2010."

The Marin County Flood Control District received proposals from two teams of consultants in response to our Request for Proposals. Interviews and presentations were conducted by a panel of professional staff of the Flood Control District. The panel unanimously selected Stetson Engineers of San Rafael and their team of Marin-based consultants to carry out the feasibility study. The other team members are: Miller Pacific Engineering, Noble Consultants, Geomorph, WRA - Environmental Consultants, MIG Inc., Michael Rex and Associates, and Studio Green Landscape Architects. The contract will go before the Board of Supervisors on March 3, 2009 and Stetson will begin work immediately after. Stetson has already started gathering data and preparing to launch this study. The study is expected to take one year and will examine the feasibility of using detention basins for flood flow reduction and look at solutions for maximizing creek flow capacity and sediment removal in the lower, tidal area of the watershed.
