Welcome to the State of California

Current Activities

Coastal RSM Plans - CSMW is working with various regional partners along the California coast to develop strategies to address coastal erosion through beneficial ruse of clean sediment from inundated areas within that region. As of December, 2015, five Plans have been completed, one is expected to be released for public review in January 2016, and four others are addressing issues in advance of their public review

SMP Implementation Workshops - CSMW is currently hosting a series of Workshops in regions where a CRSMP has been prepared, in order to gain input from stakeholders on how best to implement the Plans within those regions and address RSM across coastal California. The workshop series is expected to be completed in Spring 2016, with a deliverable document focused on state-wide (coastal) implementation of RSM.

Spatial Data Website and Database CSMW has compiled an extensive database containing both statewide and regionally-based spatial information layers relevant to sediment management. They have developed a third-generation viewer to simultaneously display various layers compiled by CSMW, as well as additional layers and GIS servers identified as relevant in their GIS Users Survey. Website users can also download CSMW layers to their own computer. The website and database is updated periodically as information becomes available from various CRSMP efforts.

Coastal References Searchable Database - CSMW has compiled an extensive database of coastal references relative to sediment management. The database can be searched by pre-defined categories as well as by author, title and region. CSMW continues to augment the database with references collected during various Coastal RSM Plan preparations.

Orange County Sand Management Plan - CSMW is working with the Orange County Parks to develop a Sand Management Plan to help the Orange County/Newport Bay region maintain beach widths through beneficial use of upland and coastal sediment. The project will prioritize potential restoration locations and sediment sources, provide additional environmental information at each of the sites that will facilitate environmental permitting and review, and recommend activities that will help move RSM forward in Orange County.

Surfers Beach and Pillar Point Harbor - CSMW is part of a stakeholder workgroup, which includes USACE, NOAA Sanctuaries, the San Mateo County Harbor District, recreational beach users, and other stakeholder groups striving to find ways to address coastal erosion at Surfers Beach (aka El Granada Beach) in Half Moon Bay. The workgroup's current focus is to determine how sediment accumulating inside the adjacent Pillar Point Harbor could be beneficially used at Surfer's Beach, given strict regulatory limitations on the placement of dredged materials within the Monterey Bay National Marine Sanctuary.

NOAA Sanctuaries - CSMW and NOAA are working together to develop approaches that would allow for environmentally-sensitive sediment management activities within the boundaries of the Monterey Bay and Greater Farallones National Marine Sanctuaries.

Depth of Closure - CSMW is working with the USEPA, a workgroup member, to assess the merits associated with various definitions of depth of closure. The chosen definition will influence the USEPA’s determination of whether individual dredge-placement projects are beneficially reusing sediment or conducting disposal activities.

Fine-grained sediment - CSMW supports research, demonstration projects, and science transfer regarding the sources and dispersal of fine-grained sediment in the coastal near shore. Communicating the results and implementing the findings, including assessing beneficial reuse options, will allow for more efficient sediment management along the California coast.
