The purpose of these regulations is to avoid, or in appropriate circumstances, to minimize, rectify, reduce or compensate for impacts arising from land development and other activities affecting wetlands, and to maintain and enhance the biological and physical functions and values of wetlands with respect to water quality maintenance, storm water and floodwater storage and conveyance, fish and wildlife habitat, primary productivity, recreation, education, and historic and cultural preservation. When avoiding impacts is not reasonable, mitigation shall be implemented to achieve no net loss of wetlands in terms of acreage, function and value. [Ord. 362 § 3, 2004.]
