9 <br /> <br />Impervious Surface Coverage <br /> <br />The allowed impervious surface coverage in the GB, General Business District is 75%. The <br />proposed impervious surface coverage of Lot 1 is 72%. The proposed post-development <br />impervious surface coverage is compliant. <br /> <br />Traffic Study <br /> <br />A formal traffic study is not required. The updated 2020 I-35E Corridor AUAR analyzed <br />traffic impacts for commercial development along this entire corridor. The proposed <br />commercial car wash is consistent with AUAR Land Use Scenarios #1 and #2 for commercial <br />development. Otter Lake Road and CSAH 14 (Main Street) are A-Minor Reliever and A- <br />Minor Collector roads, respectively, and have structural capacity to handle the commercial <br />traffic. <br /> <br />Alternative Urban Areawide Review (AUAR) <br /> <br />The site is within the 2005 I-35E Corridor AUAR environmental review boundary. The AUAR <br />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 <br />development are consistent with commercial development. No further environmental <br />assessment is required. <br /> <br />Wetlands <br /> <br />As part of Otter Crossing 1st Addition, a wetland delineation report was completed by Midwest <br />Natural Resources on September 4, 2019. A WCA Notice of Decision was issued by RCWD <br />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 <br />remainder of Wetland A. The wetlands are not within the Wetland Management Corridor <br />(WMC) so a WMC wetland buffer was not required. <br /> <br />No further wetland impacts are proposed with development of Otter Crossing 2nd Addition. <br /> <br />Shoreland District <br /> <br />The development is not located in the Shoreland District. <br /> <br />Floodplain <br /> <br />There is no FEMA floodplain on site. <br /> <br />Anoka County Highway Department <br /> <br />Anoka County Highway Department reviewed the preliminary plat and had no concerns. The <br />applicant shall obtain the required Anoka County Highway Department permits. <br />
