Our dedication to efficient, resourceful, and innovative approaches to projects stems from our belief that the North State is a unique environment that deserves careful planning and development. We assist public and private entities, local municipalities and the community with development projects, conservation projects, and natural resources management. Chico Environmental is devoted to strong advocacy of our clients' interests, personalized and responsive service, unique and innovative problem solving, educated and professional personnel, and creative approaches to meaningful mitigation of environmental impacts.


Chico Environmental has prepared hundreds of Phase 1 Environmental Site Assessments throughout the North State. 

Our assessments include a site reconnaissance, review regulatory information, and investigation of land-use history in order to evaluate environmental conditions at the site, which may have been negatively impacted by the use, storage, and/or disposal of hazardous substances.

Our assessments are conducted in conformance with the current ASTM Standard E1527-13, and include the following tasks:

  1. Review of pertinent, available documents and maps describing local geologic and hydrogeologic conditions.

  1. Review of readily available historical aerial photographs of the site and surrounding area for evidence of previous site activities and development, which could suggest the potential presence of hazardous substances at the site.

  1. Review and interpretation of archival U.S. Geologic Survey (USGS) topographic maps for information regarding historical land use potentially involving the manufacture, generation, use, storage, and/or disposal of hazardous substances at the site and adjacent properties.

  1. Interviews of personnel representing the property owner to assess the current and past land uses at the site.

  1. A reconnaissance of accessible portions of the site to assess evidence of current and/or past use of storage of toxic or hazardous materials; onsite ponds, landfills, drywells, waste streams or other disposal units; visible soil contamination, above-ground or underground storage tanks; electrical transformers containing polychlorinated biphenyls (PCBs); and drums, barrels and other storage containers.

  1. A visual review of adjacent properties to assess their potential to adversely impact the site. 

  1. Review of federal and state databases listing known or potential hazardous waste sites or landfills, and sites currently under investigation for environmental violations.   

  1. Inquiries to the local Environmental Health Department for information regarding environmental permits, environmental violations or incidents, and/or the status of enforcement actions at the site or adjacent properties.

  1. Investigation of potential contamination from offsite migration of hazardous solids, liquids and vapors that could lead to a historical recognized environmental condition (HREC), controlled recognized environmental condition (CREC) or active recognized environmental condition (REC) in connection with the property.
