PAR Environmental Services

What PAR Environmental Services does

PAR Environmental Services, Inc. is a privately held California corporation founded in 1982 and headquartered in midtown Sacramento, operating as a boutique professional services firm providing cultural resources management and environmental planning services. The firm is organized into two departments: Environmental Planning, which delivers CEQA and NEPA compliance documentation, environmental impact reports, and technical studies primarily for transportation and public works projects in California; and Cultural Resources Management, which provides archaeological inventories and excavations, built environment surveys, Section 106 compliance, National Register nominations, HABS/HAER recordation, and public interpretation products across California and other western states. The company employs 1-10 people, is a certified woman-owned business enterprise (WBE), and is led by co-founders Mary L. Maniery (CEO, Director of Cultural Resources) and James G. Maniery (CFO, Director of Environmental Planning), both of whom are directly involved in client delivery.

The firm's underlying technology stack centers on conventional GIS/GPS tooling, specifically ArcView software and Trimble sub-meter GPS hand-held units, used to map sites and collect locational data for archaeological and environmental field projects. There is no evidence of proprietary software products, no AI/ML capabilities, and no digital platform; the offering is delivered as labor-based consulting rather than as a technology product. The company maintains an in-house laboratory facility alongside its main office and has continuously occupied its midtown Sacramento location, in close proximity to the State Capitol, for over 35 years.

PAR's business model is direct professional services consulting, with revenue generated through project-based contracts with federal, state, and local government agencies (Caltrans, US Forest Service, US Army Corps of Engineers, California Department of Parks and Recreation, City of Sacramento) and large engineering/utility clients (AECOM, CH2MHILL, Pacific Gas & Electric, SMUD). Pricing is project-scope-based and not publicly disclosed. The go-to-market is sales-led and relationship-driven, with principals directly available to clients; the firm has completed over 150 environmental documents and technical studies and has delivered work in more than 70 counties across California, Nevada, Texas, Oregon, Washington, Arizona, and New Mexico. The company is founder-controlled with no external institutional investment, no parent entity, and no subsidiaries.
