Introduction

 

 

 

Purpose and Authority

 

California Government Code Section 65302(d) provides that the general plan shall include a conservation element for the conservation, development, and utilization of natural resources. To the extent applicable, the following issues must be addressed . . . water and hydrology, forests, soils, rivers and other waters, harbors and fisheries, wildlife, minerals, and other natural resources. State Code Section 65302(d) also notes: "That portion of the conservation element including waters shall be developed in coordination with any countywide water agency and with all district and city agencies which have developed, served, controlled, or conserved water for any purpose for the county or city for which the plan is prepared."

Overview

 

The Existing Conditions Report, a summary of which follows, outlines four relevant conservation issues for the City of El Segundo: coastal resources, water resources, biotic resources, and mineral resources. At this time, each of the resources identified also have planning implications in regional, statewide, and federal contexts. A partial list of agencies and projects with concerns and influences over these resources is located at the end of the Report. Following the Summary of Existing Conditions are the statements of goals, policies, and implementation measures designed to guide the management and conservation of specified resources for the City. Air quality assessment is addressed in the Air Quality Element. A discussion of soils and geology may be found under the seismic section of the Safety Element. The Open Space, Land Use, and Circulation Elements also address concerns that will overlap to some extent with Conservation.

The relevance of the Conservation Element has increased with the realization that many resources are finite and nonrenewable, and others, such as air and water, are essentially our life support systems where quality and availability may become critical. For the City of El Segundo, relevant resource conservation issues have changed somewhat over the decades of this century as patterns of living and working in the area changed. The composition of the air, the waters, and the vegetation have changed as dramatically as the forms and composition of the built environment have over the years. There is, and always will be, however, basic relationships between natural and man-made systems that must be valued and protected.

Due to the regional context of resources such as water, coastal access, and oil fields, it is necessary that the City cooperates with adjacent communities and with federal, state, and regional agencies to maintain and improve the quality of these resources and the environment. In regards to the protection of biotic resources such as the urban landscape, the City shall develop programs that promote community-wide conservation. The City shall require new development to incorporate sound conservation principles and mitigate any negative environmental impacts consequent to development within or bearing upon the City. The following goals reflect the community's needs and values and are intended to provide direction for the conservation, development, and utilization of the City's natural and man-made resources.

Summary of Existing Conditions

Coastal Resources

 

The western boundary of the City of El Segundo includes 0.8 miles of shoreline that is located adjacent to Santa Monica Bay and is owned by the State Lands Commission. This coastal area hosts two coastal-dependent energy facilities and has been developed primarily as a resource for industrial use. It serves as a marine terminal for loading Chevron Refinery petroleum products and provides a source of industrial coolant water for both Chevron and Southern California Edison. The Hyperion Treatment Plant and Scattergood Power Plant are situated nearby on property located within the City of Los Angeles boundaries.

The beach area is subject to erosion from littoral transport and storm damage. Protective rock revetments, a groin, and beach replenishment projects were implemented. No formal evaluation of these improvements is available at this time.

Both the Chevron Refinery and Southern California Edison facilities discharge waters through outfalls into Santa Monica Bay and are required to comply with permits issued by the Regional Water Quality Control Board. These discharges affect the near-shore water temperature, chemical composition, and turbidity.

Chevron maintains an on-site response capability for the small oil spills that occur occasionally during tanker offloading at the marine terminal and is a member of the industrial network for larger spills.

Recreational use is relatively light due to the industrial nature of the area and the proximity of more attractive beaches. The beach is publicly-owned and is accessible for public use through Dockweiler State Beach to the north and Manhattan State Beach to the south. No access to the shoreline exists within City limits.

Recreational uses include swimming, surfing, fishing, and coastal access. A coastal bicycle trail, maintained by the County of Los Angeles, is located on leased land above the high-water line.

 

Biotic Resources

 

The native vegetative cover has been displaced by urban structures, surfacing, and plant species typical of the residential and commercial landscaping of the region. Remnants of coastal strand vegetation, once abundant along the dune areas, exist only in scattered patches. Much of the dune area is disturbed by industrial development and beach facilities. The primary vegetation of the City of El Segundo now consists of domesticated species introduced over the last century and includes a variety of lawn grasses, ground covers, shrubs, and trees planted for their ornamental and functional qualities. Planted areas include residential, commercial, and public landscapes. Close to 5,500 street trees are maintained by the City's Parks and Recreation Department. Notable specimen trees can be found on the High School grounds and at Library Park. In addition to the environmental benefits, this plant material contributes much to the atmosphere and character of the City.

Forty-six species of birds are common to the area, sixteen of which are considered year-round residents. Many species of birds feed in the near-shore waters of Santa Monica Bay. No coastal strand birds are known or likely to breed in the City's coastal area, due to its disturbed nature and absence of specific habitat. The shoreline area provides a feeding and resting zone, particularly in rocky areas. Two endangered bird species, the California least tern and the brown pelican, are known or likely to feed, fly over, and rest along the near-shore waters or beach areas. No nesting sites are known to have been established in El Segundo.

Near-shore marine fishes include anchovy, surf perch, and croakers. The waters immediately offshore do not support commercial fishing. Common marine mammals observed in the offshore area include dolphins and California sea lions.

In addition to domestic pets, mammals and reptiles likely to occur include the California ground squirrel, house mouse, and Western fence lizard.

The El Segundo Blue Butterfly is listed on the federal endangered species list, and is dependent upon and rarely strays from coastal buckwheat plants. At this time, the butterfly occurs on a 1.96 acre preserve adjacent to and maintained by the Chevron Refinery and in the dune area under the flight path of the Los Angeles International Airport (City of Los Angeles).

Mineral Resources

 

The community's association with oil dates back to its founding in 1911 when land of the original rancho was sold to develop a second refinery for the Standard Oil Company and a company town. The El Segundo Oil Field, part of which underlies the City of El Segundo, was discovered in 1935. The field has to date produced over 14 million barrels of oil and condensate. Production has declined since 1967. Although only five wells continue to produce, the production and refining of oil resources is an important part of the City's historic and cultural legacy.
