CARLSBAD LSA FRESNO IRVINE LOS ANGELES PALM SPRINGS POINT RICHMOND RIVERSIDE ROSEVILLE SAN LUIS OBISPO April 17, 2020 Hayes Morehouse Administrative Analyst II City of San Leandro Public Works, Water Pollution Control Plant 3000 Davis Street San Leandro, California 94577 Subject: Biological Resources Habitat Assessment San Leandro Treatment Wetland Project, Alameda County, California Dear Mr. Morehouse: LSA submits this biological resources habitat assessment for the above -referenced project. The proposed project would convert an existing 4.3-acre basin historically utilized for wet weather storage to a multi -benefit wastewater treatment and shoreline resiliency project. Polished wastewater will discharge directly to the San Francisco Bay at the existing outfall located at the western edge of the existing basin. The primary objective of the assessment is to analyze the potential for the proposed project to adversely impact State -listed species and other special -status species. This assessment is based on the review of data base searches, LSA's reconnaissance -level field survey, and our project experience with biological resource issues in the vicinity. METHODS LSA Senior Biologists Dan Sidle and Bernard Warzecha conducted a reconnaissance -level survey of the project site on February 5, 2020 to evaluate the potential occurrence of special -status species and sensitive habitats on the site. Prior to conducting the survey, LSA biologist reviewed available background information/literature and searched the records of the California Natural Diversity Database (CNDDB; CDFW 2020), Inventory of Rare and Endangered Plants (CNPS 2020), and the U.S. Fish and Wildlife Service's Information for Planning and Consultation (IPaQ on-line database (USFWS 2020) for occurrences of special -status plant and wildlife species on or adjacent to the project site. We surveyed the project site by walking throughout the site to search for biological resources, such as special -status plants, animals, and their habitats, as well as sensitive habitats, such as wetlands or drainages. The potential presence of special -status species was determined based on an evaluation of the habitat types present on the site, the CNDDB records, and other occurrence information from the vicinity of the site. During the field survey, LSA also investigated the site for the presence of waters of the United States/Waters of the State (including adjacent wetlands) that would be subject to regulation under Section 404 of the Clean Water Act and/or the California Porter -Cologne Water Quality Control Act. The scientific and vernacular nomenclature for the plant and wildlife species used in this analysis are from the following standard sources: plants, Baldwin et al. (2012) and updates listed on the Jepson Herbarium website (ucjeps.berkefey.eduZeflora); amphibians and reptiles, Crother (2017) and/or 157 Park Place, Pt.
