Mariposa Biology is a biological consulting firm based in San Diego's Rolando neighborhood at 4729 Rolando Boulevard, providing environmental biology services including wildlife habitat surveys, biological resource assessments, and species identification reports. The firm, owned by Cynthia Jones Daverin (City of San Diego business tax certificate 2005015368), appears on the County of Riverside's approved biological consultant list, and landscape operations such as Wilson Woodscape Inc in Rolando represent the kind of tree and site work that triggers biological review when projects fall near riparian corridors or mapped sensitive habitat in the 92115 ZIP. That listing qualifies the firm to conduct biological surveys required under the California Environmental Quality Act and the federal Endangered Species Act for development, grading, and land-use projects across San Diego County. The Rolando Boulevard office sits south of University Avenue in a residential pocket between College Area and the La Mesa border, within the same Rolando community that houses a mix of single-family homes and small commercial parcels along the boulevard. General contractors pulling grading permits for projects near canyons, wetlands, or vernal pool habitats in eastern San Diego use biological consultants to produce the environmental documentation that city and county planning departments require, and San Diego Handyman Express Services in Rolando handles residential and light-commercial construction that can trigger those review requirements. Mariposa's scope of work typically includes vegetation mapping, protocol surveys for threatened and endangered species, and preparation of biological technical reports that feed into CEQA and NEPA environmental review documents.
