CSMW Current Activities

Coastal RSM Plans - CSMW has been 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 November, 201, 10 Plans have been completed, and the last remaining Plan covering Marin and Sonoma County coastlines is expected to be completed by early 2018

Eureka Littoral Cell Programmatic Environmental Report- The Humboldt Bay Harbor Resource Conservation District has hired a consultant team to assess, at a programmatic level, the potential impacts of sediment management activities proposed within the eureka Littoral Cell CRSMP. Report expected near the end of 2018

Surfers Beach Pilot Beach Nourishment study - 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 SMCHD has obtained funds and is directing planning activities to conduct a pilot study that will take sand from within the harbor and place it above the mean high tide line, in order to evaluate potential stabilization of bluff erosion and assess potential ecological risks associated with use of the harbor sand.

Offshore Sand Prospect Study- CSMW is consulting with the US Geological Survey and the Bureau of Ocean Management in their four-year study of potential sand prospects that could be used for coastal restoration efforts. Basic data compilation has been completed, with field work to be completed within three general offshore locations that cover federal and state waters.

SMP Implementation Report- A final Sediment Master Plan report is under construction, incorporating findings from the 11 CRSMPs and other reports prepared by CSMW since 2003. The report will focus on strategies to implement the RSM activities identified to date, and is expected to be completed in 2018.

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.

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.

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.
