State Lands Commission Set to Hear Broad Beach Project
BY BILL KOENEKER
The California State Lands Commission is scheduled to meet at Malibu City Hall on Thursday, Nov. 8 at 5 p.m.
The public hearing is about the Broad Beach restoration project. The Broad Beach Geological Hazard Abatement District is the project applicant representing 114 homes, spanning from Lechuza Point to Trancas Creek.
The commission staff has completed what the state agency calls "an analysis of impacts to public trust resources and values" for the proposed project.
The Broad Beach GHAD was formed in Sept. 2011 with the blessing of the Malibu City Council.
The GHAD applied to the Lands Commission for a lease to address extensive erosion at Broad Beach. As proposed by the district the project would address geologic hazards at Broad Beach associated with storms, flooding, beach and dune erosion and anticipated sea level rise.
The components of the project analyzed by the state agency include "placing high-quality beach material to replenish Broad Beach with "dry" sand between the dune system and the shoreline, which is part of the beach nourishment program," according to the SLC staff report.
The plan then calls for burying "the existing emergency revetment in the landward edge of the widened, nourished beach, and place imported beach-quality material over the existing revetment to create a restored dune. That requires "finding offshore beach material probably by dredging and transport to the site. The dredge beach-compatible material at an offshore site or sites would be delivered from a holding vessel via dredge discharge pipeline," according to the report.
Broad Beach resident Zan Marquis, a member of the GHAD, said that would be the preferable way or it might be delivered by truck depending on which location is chosen. He said a [source] location by Mugu Lagoon could be done by trucks.
Marquis added the South Bay location that got so much press because a couple of council members down there objected is still under consideration.
The State Lands Commission notice calls for an alternative onshore sand source. The sand could be collected from a stockpile adjacent to Calleguas Creek in Ventura County located near the intersection of Los Posas road and Hueneme Road and transport the sand by truck via Pacific Coast Highway to Broad Beach, according to the report.
A reservoir of sand "will be built to restore the dune habitat with native plant species," the report continues. "The beach itself would be widened to provide enhanced public access and recreational opportunities along Broad Beach."
"Between 1974 and 2009 approximately 600,000 cubic yards of sand was lost at Broad Beach, a majority of which has moved east to nourish Zuma Beach. On average, the shoreline moved inland 65 feet," a report from Moffatt and Nichol in April 2010 concluded.
"The sand rate turned negative in 1974 and the loss rate accelerated to approximately 35,000 cubic yards per year during the last five years.
Recent higher erosion rates during the 2009-2010 winter season necessitated that emergency precautions be taken to protect residential structures and onsite wastewater treatment systems located seaward of the residences," the report went on to state.
Consequently, the homeowners obtained emergency permits for the installation of a rock revetment about five feet high and 25 feet wide, to protect the existing homes along the beach, city officials noted.
The property owners are now working on getting permits to allow a permanent buried rock revetment along with the periodic sand nourishment. The California Coastal Commission is the permitting agency and will oversee the project.
GHADs, according to the planning staff, are a political subdivision of the state and are formed in specific geographic areas to address potential geological hazards.
The purpose of a GHAD is to prevent, mitigate, control or abate defined geologic hazards through maintenance improvements or other means.
Financing of a GHAD is accomplished through an assessment of only those property owners who own real estate within the boundaries of the designated district, issuing and serving of bonds, notes or other debentures is also authorized under a GHAD.
The assessment was based on an engineer's report, which was prepared by ENGEO, Inc, according to city planners.
The assessments and associated financing of the GHAD improvements would be overseen entirely by the GHAD board.
The document prepared for the public hearing may be viewed electronically in PDF format on the CSLC Internet website at www.slc.ca.gov and copies are also available at Malibu City Hall and the Malibu Library.
