History

The estuary mouth fluctuated along the beach while 40,000 years of coastal uplift raised the mesa to the east and west. Since the late 19th century, Santa Barbara residents have been modifying the Goleta Beach area. Cattle grazing in the watershed begun in 1846 and fires caused hillsides to erode and fill parts of the Goleta Slough with sediment. In the early 20th century, local landowners invited citizens to bring fill to the beach on which a state beach park was established. Meanwhile, in 1943 the federal government continued the filling of the estuary when it bulldozed the historic Mescalitan Island just inside the estuary to create an airbase for use during

(SBCPD, 2003). In the 1960s, further construction continued on the wetlands including a sewage treatment facility and

Highway 217, and the state park was turned over to Santa Barbara County.

Erosion

An ongoing problem concerning Goleta Beach is coastal erosion; sand and sediment is constantly being washed away and the beach is narrowing. In fact, in the last 14 years, the beach has been eroding at an average rate of -per-year. If no action is taken, the park, which consists of outdoor grills, horseshoe pits, a playground, public restrooms and shower, five parking lots and other county-maintained facilities (SBCPD, 2006), as well as the restaurant building is in danger of being lost. However, some proposed solutions designed to absorb wave energy and prevent erosion — particularly the so-called “hard engineering” solutions — may increase erosion elsewhere or alter the south central coast littoral cell. A number of plans have been proposed by different stakeholders and they generally fall under three broader philosophies. The first belief is that the park must be saved at all costs and supporters have argued for “hard engineering” coastal defense. A second group of stakeholders on the opposite extreme of the spectrum calls for managed retreat where existing utilities and structures are ripped out and nature is allowed to take its course. A third option, a moderate compromise suggests that the current ‘soft’ beach nourishment strategy is worth continuing.

Coastal defense

The structural proposals consist of numerous strategies. One possible structure is a

breakwater Breakwater may refer to: * Breakwater (structure), a structure for protecting a beach or harbour Places * Breakwater, Victoria, a suburb of Geelong, Victoria, Australia * Breakwater Island, Antarctica * Breakwater Islands, Nunavut, Canada * ...

. Breakwaters are placed a few hundred feet offshore and create a harbor. Unfortunately, a breakwater would likely adversely affect littoral drift and the creation of a Goleta Bay harbor is probably too extreme. Another strategy is the installation of

groyne A groyne (in the U.S. groin) is a rigid aquatic structure built perpendicularly from an ocean shore (in coastal engineering) or a river bank, interrupting water flow and limiting the movement of sediment. It is usually made out of wood, concrete ...

s (or groins), wood or concrete ‘fences’ that stretch out into the ocean, perpendicular to the beach. Groynes cause sediment to build up on one side but have the unhelpful consequence of preventing sediment to accumulate on the other side. Another structure proposed is a

seawall A seawall (or sea wall) is a form of coastal defense constructed where the sea, and associated coastal processes, impact directly upon the landforms of the coast. The purpose of a seawall is to protect areas of human habitation, conservation, ...

. A seawall is a concrete wall placed against the base of bluffs or sea cliffs that runs parallel to the ocean. While a sea wall may appear to be stopping erosion, a seawall can only diffuse wave energy which means that the areas on either side of the wall are likely to experience accelerated erosion. Again, this is not desired as the UCSB mesa might be adversely affected. A fourth type of structure is a

revetment A revetment in stream restoration, river engineering or coastal engineering is a facing of impact-resistant material (such as stone, concrete, sandbags, or wooden piles) applied to a bank or wall in order to absorb the energy of incoming water an ...

. A revetment is similar to a seawall but usually consists of boulders piled at the base of cliffs. While it is less likely to accelerate erosion to either side, the area in front of a revetment may suffer. Sediment that would normally have been deposited on the beach instead bounces off the rocks and is dispersed elsewhere.

Managed retreat

Some organizations of users, such as the

, have called for managed retreat. Scientists and coastal engineers know that hard structures cause greater erosion of the beach sand. This option would protect coastal resources while preserving park amenities by reconfiguring them. There is no evidence that the current protection measures currently in place have caused the erosion of beach sand at either Goleta Beach or any down coast beaches. The California Coastal Commission permits armoring in order to protect public access and recreational uses. This beach is visited by over 1.4 million visitors annually.

Beach nourishment

A third strategy is that of

beach nourishment Beach nourishment (also referred to as beach renourishment, beach replenishment, or sand replenishment) describes a process by which sediment, usually sand, lost through longshore drift or erosion is replaced from other sources. A wider beach c ...

(a ‘soft’ approach). Nourishment consists of depositing sand on top of the beach in order to expand its width. This approach is not extremely expensive and is already being done at Goleta Beach. In addition to the direct transporting of sand to the beach, it would also be helpful if sediment built up in upriver basins (behind dams) be removed and placed slightly downstream to be naturally washed down to the ocean. The mouth of the slough should be kept open by periodic dredging as blockage causes

eutrophication Eutrophication is a general term describing a process in which nutrients accumulate in a body of water, resulting in an increased growth of organisms that may deplete the oxygen in the water; ie. the process of too many plants growing on the s ...

. The Northern Gold Coast Beach Protection Strategy is an example of a successful execution of this technique. Between 1992 and 1999, the Gold Coast City Council worked with experts on a proposed plan to stop beach erosion. Options originally considered included groynes, breakwaters, and others but the City Council finally chose to

sediment from the nearby Gold Coast Broadwater, pump it through large pipes, and deposit it along five kilometers of coast. In addition, they planned a near-shore artificial reef to protect the project. Between 1999 and 2000, the plan was carried out with 1.1 million cubic meters of sediment being transported from the Broadwater to the beach (Jackson, 2004). Further dredging of nearby areas provided sand that was used to fill large

sandbags that were dropped nearshore to create the reef. Since then, the beach has been monitored with coastal imaging technology and has fared well. Due to the significant differences in the coastline and tidal conditions, this alternative may not be applicable at Goleta Beach. The area in dispute is currently fully armored with large boulders to the west of the restaurant building and has been so for a number of years. Another option on this project is to request the Coastal Commission to permit the existing rocks. There is no scientific evidence that the current protective measures have resulted in loss of sand to down coast beaches.
