Electronic Document Retrieval Instructions


Planning, Building & Environmental Services uses the electronic document storage system OnBase to store records related to specific addresses/Assessor’s Parcel Numbers. This database may not contain all documents for a particular location and not all documents are printable from OnBase. If you do not find what you are looking for or have questions, please contact the Department Monday through Friday 8:00 AM to 5:00 PM at (707) 253-4417.  Please contact Napa County Public Works for questions related to the Local Oversight Program at (707) 253-4351.


There are two ways to search for records:

Hazardous Materials Releases and/or Documents

This search returns Unified Program documents (Hazardous Materials Business Plan, Hazardous Waste, Underground/Aboveground Storage Tanks, and CA Accidental Release Prevention Program). Unified Program information may also be found in the California Environmental Reporting System: http://cers.calepa.ca.gov/. The search also returns documents related to spills or releases of hazardous materials and closed Local Oversight Program (leaking underground storage tank) documents.


All Documents

This search returns all documents related to a specific location. It includes all documents found in Hazardous Materials Releases and/or Documents and documents related to land use, food, water, pools and spas, or sewage. The search can be customized to return documents related to specific programs.
