remediation of any spills or leaky tanks. <br />intersection of Sunwood Dr NW <br />and Ramsey Blvd also has <br />underground storage tanks that <br />are double -walled. <br />The city will continue to work to <br />implement these measures. <br />13.3 <br />When assembling the issues that were to be addressed as <br />part of this AUAR, it was noted by the Anoka Conservation <br />District and by the DNR that there is a possible connection <br />between the increased demand for municipal groundwater <br />and the observed lowering of wetlands in the vicinity of <br />Municipal Wells 3, 4 and 5. Appendix F was prepared to <br />assess the general magnitude of the problem and the <br />solutions required to address the issue. It is now apparent <br />that the wetlands in question experience natural drying <br />during periods of relative low precipitation. The <br />photographic history included as part of the Wetland <br />Delineation report shows wetlands in the vicinity of the <br />COR site disappearing during the mid to late 1980's which <br />is prior to the development of the municipal wells. This <br />same phenomenon occurs again in the mid to late 1990's <br />and prior to the installation of Wells 4 and 5. The evaluation <br />also found, as stated earlier, that drawdown levels in the <br />FIG (Franconia Ironton -Galesville) unit are minimal and, <br />therefore, could not be influencing the wetlands. To verify <br />these finding, however, it is recommended that long term <br />monitoring be performed. <br />The city will continue to work to <br />implement these measures. <br />The city installed two monitoring <br />wells near the intersection of <br />Armstrong Blvd and Bunker Lake <br />Blvd. The wells record water <br />levels every 15 minutes. <br />The city will continue to work to <br />implement these measures. <br />The 10-year update to the <br />Drinking Water Supply Plan <br />contains water level records for <br />the monitoring wells and <br />production wells and long -tern <br />trends do not show an influence <br />on the groundwater levels near <br />Lake Itasca. <br />13.4 <br />There is also some concern that increased pumping in the <br />FIG aquifer could impact private wells that pump from this <br />aquifer. Again, the residual drawdown levels in the FIG <br />average 5- to 10-feet during the peak summer pumping <br />Permits were secured for previous <br />projects and will be obtained for <br />future projects. <br />Permits were secured for previous <br />projects and will be obtained for <br />future projects. <br />8 <br />Mitigation Plan Update - 2018 <br />November 2018 <br />
