3.0 PROPOSED BEACH FILLS AND CONCEPTUAL

DESIGNS

This section describes each of the six beach fills and their respective designs. The descriptions of

proposed beach fills outline the site-specific information of each beach fill including volume of

material, grain size of acceptable materials, beach fill designs which may be suitable for each

site, and sand placement rate and timing. Each of the six beach fill sites have unique

characteristics including location relative to environmental resources and wetland outlets, beach

usage, and beach profile configuration. Therefore, each site will be described independently.

3.1

GOLETA BEACH

The Goleta Beach fill site (Figure 3-1) is located in the Goleta Beach County Park at 5986

Sandspit Road, Goleta in Santa Barbara County. Goleta is located north of the City of Santa

Barbara. The County Park provides numerous recreational activities including swimming,

sunbathing, surfing, fishing from the Goleta Pier, boating, a children's playground, and dining at the

Beachside Caf and snack bar. The Park also includes several public restrooms, parking areas,

structures used for storage of Park equipment and vehicles, and residential structures that are

occupied by the Park rangers.

The Southern California Gas Company maintains natural gas processing, distribution, and

storage facilities on the property located east and north of the site. Also, northwest of the site the

Santa Barbara Municipal Airport is maintained by the City of Santa Barbara. West of the site,

the land is developed with facilities and structures associated with the University of California at

Santa Barbara. South of the site is the Pacific Ocean. The Goleta Beach fill site is located west

of the Goleta Slough. During wet weather episodes, the Slough discharges into the Pacific Ocean

and is a source of sediment to the littoral cell. Recently, this site has experienced serious erosion

and a temporary rock revetment was constructed to protect the upland area. This rock revetment

was removed in November 2000 and a winter sand dike was constructed to offer protection to the

upland area.

3.1.1

Proposed Quantity and Quality of Beach Fill Material

The plan view of the proposed Goleta Beach fill is shown in Figure 3-2. The plan shows a beach

fill length of approximately 2,200 feet extending east to the pier. The volume of material

proposed for this site is approximately 100,000 cy per year. The maximum volume at this site

was determined by analyzing the beach profile configuration and designing a "best-fit" beach fill

on the existing profile with consideration of environmental resources. The "best-fit" beach fill

design starts near the MLLW elevation, with a 10:1 or 15:1 slope to an elevation slightly lower

than the back beach, then a flat berm surface to the existing back beach. This outlines the cross-

section of the beach fill and is applied to the distance of the beach fill to calculate a volume.
