The City of Los Angeles intends to improve the Rosecrans Recreation Center Sports Field, which includes the installation of a new, regulation-size synthetic soccer field, baseball field, and girl’s fast pitch softball field. The project intends to benefit the surround community by developing recreational park area. In addition, the project also involves replacement and expansion of the existing parking lot, and presents engineering design challenges due to high levels of parking lot runoff. As such the installation of permeable paving material is required to trap associated sediments, nutrients, oil and grease, organic matter, and metals. The site must also be graded to allow for positive site drainage. Multi-stage systems must also be constructed to capture and treat site and parking lot runoff through the use of bioswales, vegetated retention basins, and overflow drains.
VCA Engineers, Inc. performed the civil engineering services for improvements to the Rosecrans Recreation Center. Specifically, VCA captured stormwater runoff overflows from adjacent streets that would cause flooding and pools of standing water, by redirecting such overflow and runoff to vegetated bioswales. Construction documents were prepared which included civil drawings depicting Site Horizontal and Vertical Control, Site Paving, Grading and Drainage with local Storm Water Management Design (SUSMP), hydrology and hydraulics study, cut and fill, Erosion Control Plans, SWPPP Application (NOI only), Utility Plans, Utility Profiles, Site Sections, and Miscellaneous Sections and Details, including details of critical conditions and connections. Design included storm drain lines and potable water line connection to the street for irrigation connection. In addition all paths of travel throughout the park were designed to be ADA-compliant.
