This portal provides easily searchable, direct access to many documents electronically produced or digitally scanned by DEEP. Please Note: At the current time, there are a limited number of documents available through the Search Portal. Please review More Information and FAQs for a list of the currently available Agency program documents, field definitions, and updates. More and more documents are continually added.

Through this portal (which contains all kinds of data provided by Connecticut State Agencies), you can access many data subsets in the environment and natural resources category — all of which can be quickly searched, sorted and tabulated.
Through this automated geographic storage and retrieval system that DEEP maintains, you can access and analyze large amounts of spatial mapping and file data over any selected geographic area in the state.
