What HELIX Environmental Planning, Inc. does

HELIX Environmental Planning, Inc. is an employee-owned environmental consulting firm founded in 1991 and headquartered in La Mesa, California, that delivers CEQA/NEPA compliance, biological and cultural resource studies, regulatory permitting, habitat restoration, landscape architecture, acoustics, air quality, and paleontological services to public and private clients across California and the western United States. The firm operates through seven regional offices spanning San Diego, Los Angeles, Sacramento, Placer, Orange, and Riverside counties plus the Bay Area, allowing it to provide localized coverage for clients such as NAVFAC Southwest, Marine Corps installations, SANDAG, UC San Diego, Rady Children's Hospital, Southern California Edison, and San Diego Gas & Electric. Its service catalog is organized around eleven core technical disciplines and applied across thirteen sectors including transportation, water resources, federal/military, energy and utilities, private development, healthcare, education, airports, mining and reclamation, telecommunications, and solid waste and landfills.

The business model is professional services revenue generated through project-based fees and multi-year on-call contracts, with competitive bidding on government RFPs and IDIQ vehicles (including a $30 million, five-year NAVFAC Southwest contract covering California, Arizona, and Nevada) supplemented by direct private-sector engagements for developers, utilities, hospitals, and universities. Pricing is project-specific, determined by scope, complexity, and regulatory requirements, and is not publicly disclosed. The go-to-market relies on direct client relationships, federal and state procurement qualifications, professional reputation, and a modest organic social presence rather than outbound sales or channel partners. The firm holds multiple licenses, registrations, and certifications across its technical disciplines and has received industry recognition including an ENR California Best Project award in 2016 and Exceptional ACASS ratings from federal clients, supporting its qualifications-based positioning for government work.
