Wetland Identification and Education
 
 

Are There Wetlands On My Property? 

Department staff conduct wetland determinations for the public. This free service is usually conducted offsite (i.e., at their desk). Occasionally staff will visit the site as part of the wetland determination process.

If the determination reveals that wetlands are likely, and there are development plans for the site, you may need to hire a consultant to do a wetland delineation, which is a detailed mapping of the wetland boundaries. Consultants also usually handle the removal-fill permit process for landowners.

As part of the permit application process, wetland delineations must be submitted to the Department of State Lands for review and concurrence. Delineations show which areas on a property are subject to regulation - i.e., a removal-fill permit - and which areas might be avoided in developing the project plans.
