City of Santa Monica Los Amigos Park Storm Drain Runoff Harvesting and Direct Use Demonstration This project was the recipient of awards from the ASCE, CASQA, and Storm Water Solutions magazine. Senior Engineer providing construction support for the design of a demonstration project that tapped into an existing storm drain line running along a school athletic field and the City of Santa Monica's Los Amigos Park, rerouted stormwater and dry - weather flows from the storm drain through a vortex system into a cistern, treated the stormwater and dry -weather runoff, and delivered highly -treated non -potable water to the park irrigation system and indoor plumbing for toilet flushing. The project's purpose was to demonstrate the feasibility of harvesting local water resources such as storm drain flows to decrease potable water use, reduce polluted urban runoff discharge to the receiving water body, and protect the future of California's water supplies. Other tasks performed included: developing a project study report, performing a geotechnical investigation and utility search, preparing design PS&Es, obtaining regulatory approvals, public education and outreach, preparing a SAP, assisting the City in report preparation, and designing educational signage. City of Culver City Washington Boulevard P3 Urban Runoff Diversion Design support providing drainage reviews for a diversion system that will capture stormwater and urban runoff from a 40-acre drainage area. This system is expected to capture approximately 115,600 cubic feet of stormwater runoff. Tasks performed include preparing a geotechnical report summary, gathering data for the existing hydraulic model, revising concept drainage areas, modeling the existing storm drain under Washington Boulevard using WSPG, modeling the reconfiguration of pipes and sewer flows, and providing calculations for the dewatering permit, drainage area, and free -falling water. Additional tasks include developing project concepts for diversion and bio- filtration systems, conducting an environmental study, coordinating with the City of Los Angeles and LACPW, performing a topographic survey, conducting a utility search to identify existing or planned future utility conflicts along the proposed project components, preparing preliminary and final PS&Es, providing community outreach, and providing construction support. City of Los Angeles Peck Park Canyon Enhancement Proposition O Pre -Design and Design Senior Engineer for the pre -design, constructability review, value engineering, and design of water quality enhancements, and slope and channel bank stabilization measures for Peck Park Canyon, which is comprised of 31 acres of undeveloped land within the 76-acre Peck Park. These improvements resulted in slope stabilization, reduced channel bank erosion, and naturalization throughout the canyon including the implementation of bioswales and detention ponds in tributary drainage areas. The various BMPs were designed to improve runoff water quality both entering and leaving the canyon, and promote compliance with the Los Angeles Harbor and San Pedro Bay TMDLs. BMP alternatives were evaluated for overall effectiveness to address the expected pollutants of concern, cost-effectiveness, and ease of operation and maintenance.
