These districts are subject to additional requirements beyond those required by the WCA. The boundaries of the wetland overlay districts are identified graphically on the official city wetland map (CWM)which is hereby adopted by reference, a copy of which shall be kept on file in the office of the city clerk and shall be available for public review during all normal office hours. Wetlands in addition to those shown on the city wetland map may exist, and may be identified by wetland delineations under WCA rules. If a specific wetland delineation has been done under WCA rules, then the boundaries of the wetland overlay district for that location will be as shown in the delineation. The city may require wetland delineations to determine compliance with WCA rules and to determine administrative wetland boundaries; however, property owners may have wetland delineations done for their properties on their own initiative. The delineation must be done by a qualified professional according to WCA rules and be acceptable to the city administrator, who may require review by city consultants or a technical evaluation panel if necessary. Approved WCA wetland delineations must be provided to the city in a hard copy format and a CAD or GIS format in Hennepin County coordinates. The city administrator will have the approved WCA wetland delineations shown on the official city wetland map. Public waters are not included in the overlay district, unless a wetland is part of a public water. (Ord.No. 28 3rd series, § 1, 8-22-2005; Ord.

Whenever a wetland boundary is disputed or uncertain, the city administrator may require the submission of a registered survey of the property and field staking showing the city-designated wetland contour or a delineation of the wetland, and such other information as the director may require in order to resolve the dispute or uncertainty. The city administrator may require review by city consultants or a technical evaluation panel if necessary. No boundary change may be authorized on the basis of fill that was placed on the site after the city designated the area as part of the wetland overlay district. Persons aggrieved by a decision of the city administrator may appeal such decision in accordance with the provisions of section 78-99 of this chapter and the WCA rules. a. Delineation types.
