• Ms. Katie Larsen December 4, 2013 Page 3 6. All necessary permits must be obtained from others including Rice Creek Watershed District, MPCA, Department of Health, and the County prior to construction. 7. Utility plans and storm sewer design must be provided for review and approval prior to construction. 8. Erosion and sediment control plan and Storm Water Pollution Prevention Plan must be submitted for review and approval prior to construction. 9. The City will enforce the wetland buffer area to ensure sod/lawn areas do not seasonally flood. This creates problems for the City in the future as people believe they have additional yard to maintain. Traffic Impact Study Comments: 1. The Traffic Study looked at the 4 primary intersections along the 20th Ave corridor plus the future site driveways. However, there are several driveways accessing 20th Avenue adjacent to the site. How are these driveways impacted especially by the turning traffic into or out of the site? 2. For the intersection of 20th Avenue and Main Street was the intersection coordination signal timing for the other Main Street intersections between 20th Avenue and I -35E used for the operational analysis? 3. Although the analysis does not show any issues for the northbound 20th Avenue approach to Main Street, it appears that the approach queues in the build condition may back up and block intersections. This should be verified. 4. The roadway improvements section indicates that there are no issues at the 20th Avenue and Main Street intersection. However, the conclusion indicates that the WB left turn lane may need to be lengthened. Can this be accomplished with the new intersection improvements at the 21St Avenue intersection? 5. The analysis results show that for the Build condition the queue lengths and some of the movement Levels of Service are better than the 2019 No- Build. Why did this occur? Were improvements assumed? 6. The Traffic Study indicates that the County conducted a study that identified opportunities for 20th Avenue at Birch Street. Were these improvements considered or at least accommodated with the proposed development (i.e. right of way). 7. The analysis indicates a sight line issue at the 20th Avenue and CR J intersection. The addition of the Northpointe site traffic will only make this condition worse, therefore improvements should be considered with the initial construction of the development. As indicated in the Traffic Study, an all -way stop at the intersection would improve the approach delays and safety. A further analysis to determine if Stop Sign warrants are met should be conducted. This should be coordinated with the County. Grading Comments: 1. It appears that the rear lots for Lots 1 -4 Block 10, Lots 1 -9 Block 12, and Lots 1 -6 Block 13 discharge directly onto the adjacent property. 2. All street low points will need to identify an emergency overflow. 3. The easterly terminus of Street H will need storm sewer to contain the storm water runoff on site. 4. At the northeast corner of the project there are two locations where the existing 922 contour terminates at the property line and doesn't tie into the proposed contours.
