Description of the Project: (On following pages) Long Beach RiverPark Residential Project IS‐3 City of Long Beach Initial Study February 2021 A. INTRODUCTION Integral Communities proposes to develop 226 detached and attached single‐family homes and a 5‐acres recreational space on approximately 20‐acres of vacant land (Project Site) on the west side of the Wrigley Heights neighborhood in the City of Long Beach (City). The Project Site is bounded by W Wardlow Road on the south, the Los Angeles River on the west, the San Diego Freeway on the north and Golden Ave. on the east. Development of the southern 15 acres of the site includes a mix of residential housing types including detached single‐family homes and attached single‐family townhomes. A majority of the structures would be 2‐stories in height while those closest to W. Wardlow Road would be 3‐stories. Residential development is proposed on the portion of the Project Site located south of Baker Street and the area north of Baker Street would be landscaped as an open space and recreation area. This open space and recreation area would contain trails and a grass area. This grass area would be sufficient in size for use as a soccer field or for other active sports activities. The Project Site, owned by Oil Operators Inc., previously contained facilities used to treat production water from oil wells located throughout Long Beach and Signal Hill. Beginning
