improve Santa Monica Beach water quality by increasing the diversion capacity at the Santa Monica Pier and Pico-Kenter storm drain outfalls. The 85th percentile storm event volume would be treated and diverted from the Pier watershed to the Santa Monica Urban Runoff Recycling Facility (SMU RRF) or the sanitary sewer. The project proposes storm drain diversion and runoff storage systems at two separate storm drain outfalls, routed to two subsurface storage areas. 1.6 million gallons will be stored at the historical Deauville Beach Club site and an additional 80,000 gallons will be stored at the Pico-Kentor storm drain outfall. Albion Riverside Park Project, City of Los Angeles Bureau of Engineering, Los Angeles, CA. Structural Design Engineer. Providing design and construction support services for Albion Riverside Park. The project, located adjacent to the Los Angeles River, involves transforming a six -acre site, previously used for dairy warehousing and distribution, into a riverfront park and recreational facility that will benefit nearby disadvantaged low-income neighborhoods. In addition, the City is using the redeveloped property to increase the current capacity for managing stormwater runoff. This important water quality project is part of the City's overall efforts through the Proposition O Bond Program to improve water quality and reduce pollutant loads that are currently being conveyed to the rivers, lakes, and oceans within the greater Los Angeles area. In addition, the project is being designed to achieve a Platinum EnvisionTm rating. Mr. Olsen is responsible for the design of North Spring Street and Childcare ADA ramps that utilized both soldier pile walls and conventional reinforced concrete retaining walls. Carriage Crest Stormwater and Runoff Capture Project, Sanitation Districts of Los Angeles County, Carson, CA. Structural Design Lead. Mr. Olsen is leading structural related design and retrofit facilities for Carriage Crest Park, which was identified in the Enhanced Watershed Management Program (EWMP) as a high -priority site for a regional stormwater capture project due to its proximity to two large storm drains with a total drainage area exceeding 1,100 acres. The project components include a diversion structure to divert water from an existing storm drain system, a pretreatment structure to remove debris from the runoff, an underground structure to capture and store the stormwater prior to being discharged back into the existing storm drain system, and a rehabilitated park surface. Design objectives are to eliminate dry -weather flow from the adjacent channel and to maximize wet -weather pollutant capture. Caruthers Park Stormwater and Urban Runoff Capture Project, City of Bellflower, Bellflower, CA. Structural Design Lead. Mr. Olsen was responsible for leading the structural design elements, including the new treatment building facility, diversion structure, drop inlet structure and comprehensive specifications for the underground stormwater storage tank for the 90% design plans. Tetra Tech is providing a Project Engineering Study Report (PESR) that includes all necessary analyses to provide a recommendation for regional stormwater capture treatment and implementation. The analysis identifies the existing site hydrology, water quality, and hydraulics to determine an optimal combination of the inflow rate, storage volume, and outflow. The Caruthers Park Project consists of a gravity diversion from two separate Los Angeles County Flood Control District storm drain lines; a 72" RCP line that drains 261 acres of the Los Cerritos Channel, and a 38' wide rectangular concrete channel that drains 2,995 acres of the Lower San Gabriel River. The diverted flows pass through a pretreatment system to remove trash, debris, and sediment. The runoff is then passed into a large buried multi -chambered storage/ infiltration facility that will be treated and used to irrigate the park. Flows in excess of the required irrigation demands will pass into the infiltration gallery to be exfiltrated through the soil to eventually combine with the ground water. City of Santa Ana 25 2
