The AUAR was updated in May 2020. The AUAR identifies this site as commercial in the land use <br />scenarios. The Otter Crossing 2nd Addition preliminary plat and Tidal Wave Auto Spa development are consistent with commercial development. No further environmental assessment is required. Wetlands As part of Otter Crossing 1st Addition, a wetland delineation report was completed by Midwest Natural Resources on September 4, 2019. A WCA Notice of Decision was issued by RCWD on December 9, 2019. Two wetlands were delineated. Wetland A was 2.59 acres and Wetland <br />B is 1.19 acres. Impacts to Wetland A have been completed and mitigated via wetland credits. <br />A drainage & utility easement was dedicated on the final plat over the stormwater pond and remainder of Wetland A. The wetlands are not within the Wetland Management Corridor (WMC) so a WMC wetland buffer was not required. <br />No further wetland impacts are proposed with development of Otter Crossing 2nd Addition. <br /> Shoreland District The development is not located in the Shoreland District. <br /> Floodplain There is no FEMA floodplain on site.
