Project Title:
INNER CABRILLO BEACH BACTERIAL WATER IMPROVEMENT PROJECT

Applicant Name: Port of Los Angeles

Project Summary:

Inner Cabrillo Beach, a historical and heavily used sheltered urban beach, aquarium, and park complex is located inside the breakwater of the Port of Los Angeles, along the San Pedro shore in the western Harbor. The purpose of this project is to correct the high frequency of bacterial water quality violations that occur at Inner Cabrillo Beach, located within the breakwater of the Port of Los Angeles forming the San Pedro waterfront.

Project Component 1: A previous partial bird exclusion structure erected in 2001 was shown to have a significant positive effect, but violations have still been at high, unacceptable levels. This project component would extend a bird exclusion structure over the entire beach using a more esthetic design with much fewer poles.

Project Component 2: Remove the old outfall as a potential conduit, and investigate and repair the sources of sanitary contamination up on Stephen M. White Drive immediately above Inner Cabrillo Beach as additional transport paths to the beach other than the old outfall may exist.

Project Component 3: Re-contour the beach to raise the elevation to +9 feet MLLW and replace the sand with new, coarse beach sand to increase the porosity.

Project Component 4: Develop a resource management plan that would include management policies and practices that would optimize these resource values. This plan would include both aquatic and landside resources management, and would include a management plan for eelgrass; clean and deepen the immediate nearshore area out to the swim buoy line to remove eelgrass and fine sediments and replace with coarser sand which will prevent erosion of fine sediments and also enhance the swim area by provision of a sand bottom free of eelgrass.

Project Component 5: Extensive hydrodynamic modeling and field experiments have shown that circulation at the beach face is poor, but that water mixing and enhancement in circulation by means of a local pump can be effective in reducing bacterial concentrations at the beach face. Circulation would be enhanced in two ways, one being removal of the groin extension at the northern end of Inner Cabrillo Beach yielding a small improvement, and secondly the installation of a circulation pump(s) just outside the swim buoy line at Inner Cabrillo Beach.

Project Component 6: Storm drain overflow still drains over the beach sand in the southern corner of Inner Cabrillo Beach. and discharges occur during the larger rain events. The storm water outfalls from the northern area (that drain a large area in San Pedro) will be diverted out of the nearshore Harbor waters to the high energy area outside the breakwater.

Project Title: WILMINGTON DRAIN MULTI-USE PROJECT

Applicant Name: City of Los Angeles Department of Public Works

Project Summary:

This project will enhance Wilmington Drain via a multi-step approach including stormwater screening and treatment, enhanced public access, bank stabilization, and native vegetation restoration. A detailed design will be developed, with the anticipated participation of interested community, governmental, and environmental groups. As part of its implementation, non-native landscaping will be removed and replaced with appropriate native species. Stormwater quality will be improved using netting systems that will trap trash and debris and utilize natural materials and well-planned landscaping features, avoiding the need for destructive clearing of the channel.

The project will create a public park to provide recreational opportunities for the surrounding disadvantaged communities. The park will include multiple amenities including a fenced off-leash dog area and decomposed granite trails with educational signage will provide learning and passive recreational opportunities. The site furnishings will include tree-shaded benches, drinking fountains, picnic tables that offer visible seating and safe gathering spaces. Permanent restrooms are proposed to provide an alternative to the observed use of the channel for such needs.

Project Title: Machado Lake Ecosystem Rehabilitation Project

Applicant Name: City of Los Angeles Department of Public Works

Project Summary:
Currently, major stormwater flows conveyed through the soft-bottomed Wilmington Drain flow south through a box culvert at Pacific Coast Highway and enter Kenneth Malloy Harbor Regional Park (KMHRP) via a riparian woodland; enter Machado Lake; flow over a concrete capped earthen dam and through a seasonal freshwater marsh; and ultimately discharge to the Los Angeles Harbor via the Harbor Outfall.

Machado Lake is on the 303(d) list for impaired water bodies. It is believed that there is a build-up of polluted sediments on the lake bottom. The broad goal of the Machado Lake Ecosystem Rehabilitation Project is to improve the water quality conditions, visual aesthetics, and the biological diversity of the ecosystem to attain and sustain its desired uses and characteristics (i.e. recreational fishing, wildlife habitat, environmental education), and to meet Total Maximum Daily Load (TMDL) requirements and other water quality targets. This effort will be accomplished through integrated ecological and engineering strategies and solutions involving watershed-based management approaches, in-lake rehabilitation and streambed assessment techniques, riparian system enhancements, and treatment best management practices (BMPs) at strategic areas in the park.

Project Title: Rosecrans Recreation Center Stormwater Enhancements

Applicant Name: City of Los Angeles Department of Public Works

Project Summary:
Stormwater runoff from a site has the potential to contribute trash, oil and grease, suspended solids, metals, gasoline and pathogens to the storm water conveyance system. The Rosecrans Recreation Center Stormwater Enhancements Best Management Practices (BMP) project goal is to minimize, to the maximum extent practicable, the introduction of pollutants of concern that may result in significant impacts, generated from site runoff to the storm water conveyance system.

Stormwater enhancements include a "smart" irrigation system, porous pavers in an existing parking lot and a new parking lot (non-Prop O funded), bioswales, vegetated retention basins, decomposed granite pathways, a synthetic soccer field, and a cistern beneath the soccer field. The site will also be graded and landscaped to provide better drainage at the recreation center and to direct flows to the treatment bioswales and retention basins.

Installation of a new catch basin in the Recreation Center parking lot. Runoff from the lot will be caught by the basin and released into the channel


Construction of a side-opening catch basin, connector pipe, and outlet structure at the north end of Patton Avenue to intercept surface runoff, direct it underneath the existing upland trail, and release it into the channel.


Existing trails will be restored and widened.


Elimination of existing exotic and non-native plant species, and the restoration of the riparian corridor.


Trash cans, signs, and barriers will be installed to discourage dumping and the use of motorized vehicles.
