development. TH 10 is an Interregional Corridor (IRC). Mn/DOT plans in 2004 to rebuild Ramsey Blvd. traffic signals, and extend turn lanes. We do not believe that this modest improvement will solve the deterioration in level of service that is likely to occur at this intersection once the Town Center development is complete. Further, in 2005~ Mn/DOT plans to upgrade traffic signals, and extend TH 10 turn lanes.serving the Sunfish Lake Blvd. NW intersection. Again, we do not believe that these improvements, even though they are clearly needed, will provide a complete solution for the existing, and likely future traffic congestion at this intersection. Since there is no imminent plan for major ilnprovements to these intersections., such as the construction of interchanges, we need to work together with the City and County to find ways of providing additional roadway transportation infrastructure that will add capacity to these intersections in advance of further development. We would like to work with the City of Ramsey to explore additional funding for local and regional roadway improvements as %veil as h~itiatives that restrict the size and intensity of developments to ensure that a certain minimum level of service is maintained. Such initiatives might include binding agreements with developers where additional or increased intensity of development will only be allowed with necessary roadway improvements that maintain an acceptable level of service. Mn/DOT contacts are given. Response: MMA response exp~ie~i Comment 6.2: On page 17-10, the AUAR shows an increase in the run-off rate to Mn/DOT Right of Way. The run-off to Mn/DOT Right of Way must not be increased, and drainage patterns must be perpetuated. The development will probably need a drainage permit. When the final AUAR is submitted, it should be accompanied by drainage area maps, and storm drainage maps, and computations for 1 O-year and 100- year storms for both existing and proposed conditions. Agencies which will need to grant approval are listed on pages 8-1 and 8~2 of the AUAR. This list should be amended to include the neighboring property owner in drainage area 10 for the wetland mitigation of the bordering wetland (Wetland D - DNR Protected Water 2-670W). Figure 12-6 shows Anoka County extending Ramsey Blvd. southward into the (Mississippi Regional) park. The City of Ramsey suspended construction on the connection to TH 10 -Ramsey Blvd. for the Rivenwick development in the southeastern quadrant to TH 10 - Ramsey Blvd. until Mn/DOT finalizes plans for the intersection. Anoka County, or the Rivenwick developer, must provide an area for a storm drainage pond to handle the increased run-off from this intersection due to added lanes. Page 12-7 of the AUAR summarizes the wetland mitigation. Wetlands must be mitigated at 1 to 1, and Public Value Credits at 2 to 1. In drainage area 10, there seems to be a discrepancy in the mitigation rate. A Mn/DOT contact is given. Response: The final route for runoff from the RTC site has not yet been determined. Currently, as described in Item 17, a very small amount of runoff from the site discharges into the Right of Way and eventually infiltrates. Under the preferred drainage route, increased runoff from the site will pass through the Mn/DOT ROW and proceed southerly along a route currently owned by the County.
