Mr. Steve Rohlf • June 4, 1993 Page Seven 5. The base data for the air quality analysis was recorded at the Wedgewood Commercial Center. According to the information in Section 7.1, the base monitoring site is 15 miles from the proposed development. The adjustment factor for the base conditions appears to account for the differences in development density, as well as for regional traffic growth and the anticipated decrease in CO from vehicle emissions due to the state inspection system. 6. The projections from the analysis showed that the carbon monoxide levels will remain well below the MPCA standards. However, noise levels were projected to be above the MPCA standards at two locations. The draft permit applications proposed mitigating noise at Elk Ridge Manor by encouraging commercial traffic to use other access roads into the development. Will this adversely impact other receptors? The analysis also indicated noise levels above MPCA standards at the Burger King site. However, there is no discussion of possible mitigation or of the need for mitigation at that site. 7. The noise analysis was based upon the assumption of no deliveries after 10:00 p.m. In some commercial developments of this type, deliveries and trash pick-up • take place in the very early morning hours. Will these activities take place between 10:00 p.m. and 7:00 a.m. at this location? If so, they should be included in the analysis. G. RECOMMENDATIONS 1. The preliminary plat should be revised providing the missing information and addressing the concerns noted. 2. The grading plan needs to be revised addressing the items noted. 3. Storm drainage calculations are not adequate. They should be revised, following exactly the design policies laid out in the Best Management Practices. 4. The site plan should be revised, incorporating the issues noted relative to traffic patterns. 5. A detailed feasibility study considering all improvements necessary both internal and external, to provide service to this site should be required once the preliminary plat is approved by the City Council. • 152-0401.jun
