Much of the proposed development for scenarios 1 and 2 is in areas mapped as flood prone. <br />Comment noted. <br />Drainage ditches, pipes, and culverts are currently used to drain and route water out of the area <br />for sod farming, lessening infiltration and altering near surface hydrology. However, as <br />development proceeds, any new infrastructure including roads, homes, business, and utilities will <br />contend with flood risk. The removal of drain tiles, ditches, etc. creates an opportunity for the city <br />to restore wetland function in the area, thereby increasing infiltration and potential aquifer <br />recharge and improving ground and surface water quality, with the added benefit of additional <br />habitat and green space. The reduction of flood risk through nature -based water management can <br />help to improve the longevity of developed infrastructure, with added climate adaptation and <br />mitigation benefits. <br />The Anoka Co. Geologic Atlas reference on page 31 section 11 is out of date. An update to the <br />Comment noted. The updated <br />Anoka Co. Atlas part A was completed in 2013, with part B following in 2016. The AUAR should be <br />Anoka County Geologic Atlas was <br />updated to reflect and consider modern mapped geologic and hydrogeologic conditions. The AUAR <br />reviewed and included in Final <br />should also consider water table information included in the geologic atlas's and estimated by the <br />AUAR. <br />DNR in 2014. Soils in this area are either hydric or formerly hydric (drained hydric). These areas <br />were wetlands prior to drainage and development for commercial agricultural purposes. New <br />developments would contend with high water tables seasonally and during periods of increased <br />precipitation. <br />Item 18 — Greenhouse Gas Emissions <br />The anticipated greenhouse gas emissions are reasonable and the proposed mitigation measures <br />Comment noted. The City will <br />are appropriate. An additional mitigation measure to consider is the orientation of new homes and <br />encourage developers to consider <br />overhang designs with the sun and horizon to maximize solar energy gain during the winter and <br />home orientation and energy - <br />minimize solar energy gain in the summer. <br />efficient design. <br />Item 20 — Transportation, Transit <br />Roadways: The AUAR accurately identifies Main Street (CSAH 14) as a principal arterial. Any <br />Comment noted. <br />proposed additional or changed access to a principal arterial should consult the Transportation <br />Policy Plan (TPP) functional classification guidance before finalizing any proposed access changes <br />to a principal arterial Imagine 2050 TPP Functional Classification. <br />Page 543 of 617 <br />
