Managed Shoreline Retreat and Dam Removal: Ecosystem Restoration to Benefit Coastal Resources
Human impacts to coastal watersheds in Southern California result in long-term degradation of coastal resources. This is especially evident in two areas: the loss of recreational beaches due to beach erosion and the endangered status of native anadromous fisheries. This paper presents beach and watershed restoration efforts currently underway in Ventura County that may serve as a case study for progressive management measures leading to long-term coastal management solutions. One of the findings of California's 1997 Ocean Agenda was the need for enhanced shoreline management to address coastal erosion. Since 1995, the City of Ventura has taken the lead role in a planning process aimed at a "Managed Shoreline Retreat" at Surfers Point. The intent is to relocate a damaged bike path and parking lot in order to restore the shoreline adjacent to the mouth of the Ventura River to provide a natural sand and cobble buffer zone. Concurrently, a feasibility study is underway for ecosystem restoration related to the obsolete Matilija Dam 16 miles up the Ventura River. The objective is to restore natural watershed processes to renew the natural coastal sediment supplies and to provide fish passage to the historical spawning streams of the federally endangered southern steelhead trout. The lessons learned from these two projects will serve as a case study for watershed-based ecosystem restoration to benefit coastal resources.
