C:The design for stormwater runoff has been discussed with the City of Arden Hills in terms of available <br />capacity now and for future rainfall events, such as the expected increase in the 100-year 24-hour storm <br />even rainfall. The storm sewer system serving the project area has capacity for future climatic events.The <br />project will meet Rice Creek Watershed District rules for rate, floodplain elevation, and water quality. The <br />District is adopting the revised National Oceanographic and Atmospheric Administration’s Atlas-14 <br />standards for storm design intensity, duration, and frequency. The Rice Creek remeander portion of the <br />project will increase floodplain volume. Multiple ponds, vegetative filters, and wetland mitigation areas will <br />treat runoff water quality equivalent to a 95% treatment volume criterion. <br />D:The preparation of a Health Impact Assessment (HIA) is not a requirement of the AUAR process.The City <br />of Arden Hills appreciates the Minnesota Department of Health bringing forward through a comment on the <br />Draft AUAR the importance of preparing an HIA for major infrastructure projects. <br />E:Connections between uses and to surrounding amenities have been incorporated into the project. The spine <br />road through the development will have a trail on one side and a sidewalk on the other, and there will be a <br />supportive network of city streets to provide access to neighborhoods and businesses. Also, as discussed in <br />Section 9 of the AUAR, a 150 foot corridor will beadded toestablished to provide a trail/prairie connection <br />from County Road I to Highway 96. <br />June 2014A-4 <br />
