The proposed First Industrial Warehouse at Wilson Avenue Project and offsite improvement area involves the construction and operation of an approximately 303,228-square-foot industrial, non-refrigerated warehouse distribution facility use that includes 8,000 square feet of office space and 4,000 square feet of mezzanine space on an approximately 15.6-acre site, of which approximately 1.86 acres along the eastern portion of the site would be reserved for future expansion of the Perris Valley Storm Drain. The speculative warehouse/distribution use is assumed to operate 24 hours a day 7 days a week. The Project includes curb and gutter, curb cuts, and u-channels to convey on-site flows to the proposed water quality basin located at the southeast comer of the Project site. Additionally, two subsurface storm drain lines will be constructed; Line A and Line B. Storm drain Line A (approximately 580 linear feet) will collect the northern and eastern Project surface flows and convey them southerly to the proposed water quality basin. The water quality basin will collect Project surface flows from the southern eastside via a proposed drainage channel constructed on the west side of the basin. Storm drain Line B (approximately 200 linear feet) will connect to the water quality basin and convey the entire runoff generated from the site into the Perris Valley Storm Drain Channel. Access to the Project site will come from Wilson Avenue via two driveways; the south most driveway has direct access to the truck yard. Trucks would d use the PVCCSP-designated truck routes of Rider Street, Indian Avenue, and Harley Knox Boulevard to travel to and from the Project site.
