18.06 Article III - Development Standards for Wetland Areas
Are there wetlands on my property?
One tool available to identify wetland areas on individual properties is the National Wetlands Inventory Mapper, an online mapping service provided by the U.S. Department of Fish and Wildlife. The mapper is an indication of the presence of wetlands; however, the absence of mapped wetlands does not ensure that wetland areas do not exist on or near your property. A wetland professional can help you determine whether your property has wetlands or wetland conservation buffers that are regulated through the Critical Areas Ordinance.
