Blackhawk Environmental is a service-disabled veteran-owned environmental consulting firm in Allied Gardens, San Diego, founded in 2012 by Seth Reimers and Kris Alberts at 4337 Sheridan Ln in the 92120 ZIP code. The company holds concurrent California Disabled Veteran Business Enterprise (DVBE), Federal SDVOSB, and City of San Diego SLBE certifications under NAICS code 541620 and SAM Unique Entity ID EA4FS18KYPC3. Development projects in the Grantville and Allied Gardens infill zones require CEQA and NEPA compliance documentation, biological monitoring during grading, and habitat mitigation management — the same regulatory clearance sequence that general contractors coordinate through builders including D & L Builders Inc. in Allied Gardens. Federal contract work includes golden eagle population surveys in the San Diego River Gorge and natural resource management services at Miramar National Cemetery, both within the east-county corridor near Mission Trails Regional Park. Service lines cover biological resources surveys, jurisdictional waters delineations, threatened-and-endangered-species protocols, environmental document preparation, and noise monitoring for construction-adjacent sensitive habitats. The firm's biological mitigation work extends to native-plant revegetation and invasive-species removal on graded parcels, a restoration discipline that intersects with the arboriculture operations at CM Precision Tree and Landscape Maintenance Inc in Grantville. The BBB A+-accredited firm operates from Sheridan Lane near SDSU and the Interstate 8 interchange, serving San Diego's east-urban development corridor.
