City of Santa Ana On -Call Engineering Services (RFP No. 23-030) notifications, records research and field review for ADA accessibility and compliance, topographic survey, and preparing PS&Es. REFERENCE: Stephanie Camorlinga, Engineering Associate, scamorlinga@cityofalhambra.org Los Angeles County Metropolitan Transportation Authority Division 4 Permeable Concrete Pavement Pilot Project, July 2015 - February 2019 This project is the recipient of the 2019 ASCE MLAB Outstanding Sustainable Engineering Project award. CWE designed PCP and a bioretention facility for LA Metro at their Division 4 non -revenue facility in Downey. The project facility is a total of 251,000 square feet. An impermeable pavement area w 39,000 square feet was converted to pervious concrete pavement. The bioretention facility captures flows exceeding the 851h percentile event, and provides additional storage and infiltration capacity. During large storm events, flows exceeding the capacity of the PCP and bioretention facility are routed to an existing infiltration trench within the site and ultimately discharge into the Rio Hondo. The project benefits LA Metro by significantly reducing discharge, improving water quality, and addressing the Los Angeles River Bacteria, Metals, and Total Maximum Daily Loads (TMDLs). Tasks included: development of design parameters including stormwater retention requirements and rainfall data; design of pervious concrete pavement and retention basin, overflow swale, hand monitoring wells; development of construction plans, technical specifications, and a construction cost estimate. REFERENCE. Not Available US Army Corps of Engineers (USACE) Dulzura Brown Field Border Patrol Station, September 2017 - Present As part of the ultimate civil engineering design, CWE is preparing Caltrans format improvement plans for the widening of Highway 94. The highway widening is needed to accommodate acceleration/deceleration lanes into the entrance of the Station. Tasks include: developing road improvement plans, traffic control plans, signing and striping plans, sewer design plans, and storm drain PS&Es for approval from Caltrans. The ultimate design includes designing improvement plans for the installation of the water well pump, mechanical piping, water treatment (filtration, disinfection), and electrical power/controls for the pumps; designing tank piping and valves; developing a site Stormwater Pollution Prevention Plan (SWPPP); preparing onsite sanitary sewer plans for the collection of wastewater from each of the facility buildings; preparing plans for the treatment and disposal of wastewater flows; drilling a pilot test water well and checking pumping capacity (yield tests) of the groundwater aquifer. CWE tested water quality to assure potable water met or exceeded San Diego County and State of California water quality standards.
