Carpinteria City BeachSanta Barbara County

Shoreline Miles: 106.3 106.8;List ing Source- Survey; USACE

Set t ing: Sandy beach backed by houses,park facil it ies and adjacent t o creekmouth.Proj ect Lead: USACE; BEACONPROBLEM ASSESSMENT

This beach is highly susceptible tostorm erosion and result ing damages. Damages to the private propert y and public facil it ieswill continue as a result of shoreline retreat, storm damage, and coastal flooding. USGS

reports long-term trends of erosion to west, accretion to east; erosion hotspot migrated ontowest end of beach during 97-98 El Nino with erosion rates of 0.3-2.33 m/ year, caused byflanking erosion of updrift structure. This area is part of an ongoing USACE shorelineprotection study.

La Conchita BeachVentura County

Shoreline Mile 1.0-2.4Listing Source- Survey

Setting: Narrow to non-existent sandybeach backed by seawall and Highway101. Beach is f lanked by rockyheadlands.

Proj ect Lead: Ventura County

PROBLEM ASSESSMENT

Beach has been compromised by historical encroachment of railroad and highwayinf rast ruct ure. Recreation opport unit y exists by vir tue of lateral access. Direct access is

difficult and hampered by lack of parking. Passive erosion may be contributing to narrowingbeach width due to presence of seawall backing the beach.

Oil PiersVentura County

Shoreline Mile 3.7-3.9Listing Source- USACE; CRSMP

Setting: Narrow to non-existent sandybeach backed by seawall and frontageroad. Beach located at f ormer locat ionof pier to oil platform

Project Lead: USACE

PROBLEM ASSESSMENT

The rock revetment-backed beach at Oil Piers has narrowed in recent years due to demoli t ionof the Mobil oil pier in 1998. Shoreline erosion between the demolished oil pier locat ion andthe shoreline has increased since removal. A sand ret ention st ruct ure, or mult i-purpose reef,located offshore is proposed for this locat ion by USACE. The main goal of t he reef is to retainsand that will be placed along the shoreline, without having a negative impact to theadjacent shoreline. The reef i s also designed to enhance natural resources and recreationopportunities (i.e. surfing) as additional benefits. Passive erosion may be contributing tonarrowing beach width due to presence of seawall backing the beach.

Shoreline Miles: 5.1-6.8List ing Source- CRSMP

Setting: Narrow to non-existent sand andcobble beach, backed by massive rockrevetment and seawall. Extremely popularroadside RV parking. Hobson County Park islocated at the north end.

Project Lead: BEACON

PROBLEM ASSESSMENT:

Road subj ect to damage during high wave condit ions from wave overt opping. Passive erosionmay be contributing to narrowing beach width due to presence of seawall backing the beach.

Shoreline Miles 7.1-10.4List ing Source- CRSMP

Sett ing: Narrow sand and cobble beachesbacked by rock revetment, deterioratingconcret e seawall , Highway 101 andhomes. Emma Wood State Beach islocated at south end of the Parkway.


PROBLEM ASSESSMENT:Road and homes are subject to flooding and damage from overtopping waves during severe

storm events. Passive erosion may be contributing to narrowing beach width due to presenceof seawall backing the beach.

PROBLEM ASSESSMENT

Beach has been compromised by historical encroachment of railroad and highwayinfrastructure. Seawall has been breached historically, and park facilities and access road aresubj ect to damage during high storm condit ions overt opping seawall . Passive erosion may becontributing to narrowing beach width due to presence of seawall backing the beach.
