Fees and Restrictions
Before submitting a request you may want to see the fees for custom data requests (66 KB pdf file), data release policy and/or statement of limitations inherent to our data. The fees are designed to recoup our expenditures for data acquisition, organization, quality control, and maintenance as well as responding to these requests. Our intent is not to reduce the number of users, but to continue to be financially solvent, enabling us to offer this information to the public.
People, agencies and organizations who provide NHNM with information for our database or with access to land and waters may be exempt from charges. Students with reasonable needs for the information are exempt. If you believe your request should not be charged, contact the NHNM Information Manager.
Requests for data are processed in the order in which they are received in writing. Average response time is about two weeks from the date your request is received in our office, but it may be longer if there is a backlog or if your request does not contain all the needed information. Since our office receives many requests, we strongly encourage you to submit your request during the early stages of a project.
Rush jobs. We may be able to process your project as a priority job with a turn around time of less than two weeks. Contact the NHNM Information Manager for availability.
