Listed on the County of San Diego’s approved CEQA consultant roster for privately initiated projects, Alden Environmental, Inc. operates from 3245 University Ave #1188 in North Park. Development teams working with firms like MPA Architects engage Alden before site plans are finalized to complete required biological clearances. The firm conducts general biological resources assessments, burrowing owl protocol surveys, and habitat-mitigation monitoring across San Diego County’s coastal and inland development zones. General contractors such as American Essential Construction Group rely on Alden’s clearance documents before the County issues grading permits. The highest-value engagements involve multi-season biological monitoring and California Endangered Species Act compliance for coastal-zone developments requiring phased construction schedules.
