Document Description
Located on the west and east sides of Walnut Avenue, south of Hill Street and north of Jenni Rivera Park, 20th Street, and Alamitos Avenue, the project site consists of 8.37 acres that was formerly developed as an oil refinery. All refinery improvements were removed and the southerly sloping site consists mostly of bare soil. Development of nine 1-story and 1-story-with-mezzanine concrete tilt-up buildings, for occupancy by a variety of light industrial businesses, along with a variety of site improvements, such as surface-level parking, landscaping, and miscellaneous underground water, sewer, storm drainage, electricity, and communication lines. The project would dedicate private land for expanded public street right-of-way at the southern terminus of Gundry Avenue, along Walnut Avenue, and 20th Street. Additionally, 21st Street between Walnut Avenue and Gundry Avenue would be vacated and incorporated into the project site plan. The project also includes a soil vapor extraction system to capture and remove soil vapor gas resulting from contamination by the former oil refinery that previously operated on the project site. The project is estimated to require 18-19 months for construction and it is presumed that all buildings will be fully occupied and operational by Spring or Summer of 2023.
