San Gabriel Valley Council of Governments Rio Hondo Load Reduction Strategy Preliminary Engineering and Final Design Services Senior Engineer for a feasibility assessment along with preliminary design for the Alhambra, Rubio, and Eaton diversion locations within Rio Hondo Los Angeles River watershed in compliance with MS4 Permit requirements. The Rio Hondo LRS addresses requirements pertaining to the Los Angeles River Bacteria TMDL. The three diversion areas include Alhambra Wash, Eaton Wash, and Rubio Wash. Tasks include providing flow regime calculations and providing QA/QC for feasibility study review. Additional tasks included coordination with the LACSD to verify discharge allowed to the sanitary sewers in the area, detailed flow analysis and coordination with the LACSD and watermaster, environmental evaluation and documentation, site field investigation, topographic survey for each site, utility search to identify existing or planned utility conflicts, geotechnical evaluation to identify soil characteristics and infiltration capacity for each site, permits and easement evaluation, preliminary operations and maintenance, and preparation of a feasibility assessment report and preliminary design plans. City of Santa Barbara Bohnett Park Stormwater Treatment Senior Engineer for design plans and construction specifications for the stormwater treatment system in the 2.25-acre Bohnett Park, located within the Westside neighborhood of Santa Barbara. The project system captures, treats, and infiltrates storm water from two 18-inch storm drains. Tasks performed included checking the hydrology using Los Angeles County methods, calculating infiltration scenarios, and modeling in MODRAT and Hydraflow. Additional tasks included project management and coordination, schedule and budget tracking, and coordination with the City Project Manager; data review of storm drain records and LiDAR maps, utilities within the park, design plans for park improvements, existing geotechnical information, and the City's Stormwater BMP Guidance Manual; drainage report preparation for the stormwater capture and treatment system design and existing site conditions; geotechnical investigation including borings 15 feet below existing grade for soil classification and infiltration at three different locations within the park; preparation of two conceptual design alternatives; and preparation of PS&Es for the agreed upon alternative. This project was completed within budget and one month ahead of schedule. City of Culver City Washington Boulevard P3 Urban Runoff Diversion Hydrology and Hydraulics 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.
