Impact Analysis Appendix I: Focused Traffic Analysis Initial Study/Mitigated Negative Declaration ii Cerritos Avenue Residential Project PA140071 Project Location The project site is located in the central portion of Orange County in an unincorporated county island area that is west of the City of Anaheim’s jurisdictional limits. The site is approximately three miles west of the Santa Ana Freeway (I-5), approximately three miles south of the Riverside Freeway (SR-91), and approximately three miles north of the Garden Grove Freeway (SR-22). Regional access to the project site is generally provided by I‐5 and SR‐22 via Brookhurst Street. Specifically, the site is located along the north side of Cerritos Avenue, between Gilbert Street on the west and Brookhurst Street on the east. The site address is 9611, 9641, and 9671 West Cerritos Avenue, Anaheim (See Figures 1 and 2). Existing Setting The project area is completely developed with urban uses that include primarily residential dwellings, with some commercial and preschool facilities. The proposed project site consists of three parcels, which total 3.17 acres of land and are described below: 9611 West Cerritos Avenue: is improved with one, two-story residence, and one two-story garage with an office in the second story. Several portable sheds and a storage unit are also located on the property. The parcel is accessed by a gravel driveway, and the front yard contains irrigated fruit trees. 9641 West Cerritos Avenue: is improved with two, one-story buildings that were used as a preschool identified as Big Adventure Child Care. In addition to the structures, there is a playground and two small children’s pools on-site. The site also contains parking and several fruit trees. Although the preschool vacated the site in June, 2015, the improvements remain on site. 9671 West Cerritos Avenue: is improved with a one-story, approximately 1,300 square foot residence and numerous small structures and sheds that are used for storage. In addition, there are areas that contain animals such as dogs, cats, a pig, goats, and birds. The parcels adjacent to the project site are developed primarily with one-story single family detached dwellings. There are a few two-story single family detached dwellings that immediately abut the project site on its northerly and westerly boundaries. The residential dwellings range in size from approximately 1,300 square feet to 2,000 square feet. A multi-family residential project (apartments) are located approximately 500 feet westerly of the project site, at the northeast corner of Cerritos Avenue and Gilbert Street identified as Capstone Apartment Homes.
