Strathern Park North (Formerly East Valley Baseball Park) Stormwater Capture Project


The Strathern Park North Project will collect runoff from a 485-acre drainage area and potentially capture 282 acre-feet per year. Proposed scope of work at Strathern Park would include the installation of a 1.4-acre infiltration gallery to capture stormwater from LACFCD storm drains and the surrounding neighborhood for infiltration and replenishment of the San Fernando Groundwater Basin. The infiltration gallery would be constructed in the eastern portion of the park within a fenced, undeveloped field, west of the existing baseball fields. In addition to the gallery, other underground stormwater components will include the installation of one diversion structure, desilting basin, piping, hydrodynamic separator, and flow-measuring device.

Furthermore, the project will benefit the community with its planned enhanced recreational areas, flood control, and preservation of the surrounding nature. The Park will be improved with two new baseball fields with backstops, dugouts, batting cages, bleachers with shade, fencing, new sports lighting, hydrations stations, new permeable pavement parking lot, and EV charging stations. All components will be within RAP’s property except for the diversion structure and conveyance pipe, which will be within LACFCD’s and LADWP’s right-of-way. Environmental studies started in September 2019 and pre-design started in December 2019. Design began in October 2020. The first community outreach meeting was held in August 2020.
