<br />Report (PESR) that represents 10% design completion level and describes the evaluation of the two
<br />sites with all site investigation, hydrology and hydraulic, and water quality data and analyses to provide
<br />a recommendation for site selection. The project components will include a diversion structure to divert
<br />water from one of the major flood control channels, a pretreatment structure to remove debris from
<br />the runoff, an underground structure to infiltrate or capture the water that will be treated for landscape
<br />irrigation use, and a rehabilitated park surface with new picnic areas. The goal of the project is to not
<br />only help the City comply with the metals Total Maximum Daily Loads (TMDLs), as presented in the
<br />Los Cerritos Channel Watershed Management Program, but also provide additional benefits, such
<br />as revitalized park infrastructure and augmentation of local water supplies. Currently, Tetra Tech is
<br />providing design services to prepare final plans, specifications and estimates for the City.
<br />Aliso Creek — Limekiln Creek Restoration Project, City of Los Angeles Bureau of Engineering,
<br />Los Angeles, CA. Senior Project Manager. Responsible for overseeing pre -design and design services
<br />for this important Proposition O project. The project is located at the confluence of the concrete lined
<br />Aliso and Limekiln Creek flood channels, which merge together in the southern portion of the project
<br />site. The project improvements involve constructing several stormwater Best Management Practices
<br />(BMPs) intended to treat on -site and off -site runoff and reduce contamination in Aliso Creek, Limekiln
<br />Creek, and the Los Angeles River. The proposed BMPs include low flow channel diversions, stormwater
<br />pump stations, stormwater pre-screening devices, bioswales, vegetated detention/retention basin,
<br />the restoration of upland, riparian habitat, and BMP educational signage. The goal of the project is to
<br />significantly reduce the pollutant loads, as well as transform a specifically built flood control facility into
<br />a multi -function green infrastructure facility. The project will also be designed to achieve a Platinum
<br />Envision Rating. This important water quality project is part of the City's overall efforts through the
<br />Proposition O Bond Program to improve water quality and reduce pollutant loads that are currently
<br />being conveyed to the rivers, lakes, and oceans within the greater Los Angeles area.
<br />Statewide Stormwater On -call Services, State of California, Department of Transportation
<br />(Caltrans), CA. Project Manager for several task orders for an on -call stormwater services contract
<br />with Caltrans. The engineering services for the task orders include hydrology/hydraulic design of
<br />treatment Best Management Practice (BMP) pilot projects; reconnaissance studies of new treatment
<br />BMPs; preliminary design reports; and plan, specification, and estimate preparation for treatment BMP
<br />pilot projects.
<br />Temescal Canyon Park Stormwater BMP Project, City of Los Angeles, Bureau of Engineering,
<br />Los Angeles, CA. Project Manager. Project Manager for a project to assist the City in compliance with
<br />the Santa Monica Bay Beaches Bacteria TMDL near Temescal Canyon Road. The engineering services
<br />for the project included concept development, preliminary design, detailed design, construction support,
<br />hydrologic analyses for the performance of the facility, site surveying, support of CEQA activities,
<br />environmental services, archaeological services, geotechnical explorations, permitting (Coastal, City
<br />Building and Safety, Caltrans, and Los Angeles County), and community outreach. Components of the
<br />BMP are a 22 million gallons per day (mgd) storm drain diversion structure; a hydrodynamic separator;
<br />a 1.25 million gallon detention tank; a 3 mgd pump station; new park playground equipment; new
<br />park restrooms; 500 feet of new 36-inch storm drain pipe; 1,000 feet of new 16-inch force main; and
<br />rehabilitation of 3,000 feet of existing 16-inch force main that discharges into the sanitary sewer for
<br />treatment at the Hyperion Wastewater Treatment Plant.
