Rincon Consultants

What Rincon Consultants does

Rincon Consultants, Inc. is a California-based environmental consulting firm founded in 1994 by five scientists and planners and headquartered in Ventura. The firm provides multidisciplinary environmental, planning, and engineering services through six technical groups: Environmental Sciences and Land Use Planning, Biological Resources, Site Assessment and Remediation, Water Resources, Sustainability Services, and Cultural Resources. Its 450+ professionals, organized across 14 California offices, deliver CEQA/NEPA documentation, regulatory permitting, biological and cultural resource surveys, climate action and adaptation planning, groundwater sustainability work, and construction-phase environmental compliance for public agencies and private developers.

The firm supplements its consulting practice with three proprietary digital products: CAPDash, a customizable web-based dashboard for Climate Action Plan measure tracking; Housing Connect, a SaaS-style tool for California local governments to analyze, manage, and report residential development under Housing Element requirements; and the Groundwater Rise Screening tool, which identifies contaminated sites vulnerable to climate-driven groundwater rise. Underlying technology includes Esri ArcGIS Online platforms, drone-based aerial data collection and orthoimagery, geospatial mapping, and custom technical graphics, supported by a new Chief Technology Officer function established in January 2026 with explicit mandates for data and analytics governance and artificial intelligence integration.

Rincon operates a project-based professional services model, earning revenue through competitive proposals, on-call multi-year contracts (notably with Metropolitan Water District of Southern California since 2011), and subcontractor roles on large infrastructure programs including California High-Speed Rail, the SANDAG Mid-Coast Corridor, and the West Santa Ana Branch Transit Corridor. Go-to-market is sales-led enterprise field sales targeting government agencies, utilities, transportation authorities, and private developers, with pricing not publicly disclosed and structured on a project-by-project basis. The firm is privately held as a California S Corporation with no disclosed parent company or external investment prior to a January 2026 capital raise of approximately $1.45 million.

Direct competitor for the same City, County, and Water District on-call contracts.
