the City and the developer. It is anticipated that Mn/DOT will ultimately be part of the discussion as well as the design details for crossing TH 10 develop. Coln~ncnt 12.10: In Section 12 - Drainage Area 26, a portion of the storm water connection to the Mississippi River is proposed to be in Mississippi West Regional Park. Coordination witln Anoka County Parks is required for any work proposed in the park. If storm water management for the Town Center development is done in the park, appropriate mitigation should be provided. Public park land that was purchased/donated tbr park purposes that is used to manage storm water for an off-site developmen.t should be replaced with comparable parkland. Figure 12.4 indicates that some of the wetland mitigation will take place in the regional park. If land within the park is utilized for wetland mitigation for the Town Center development, this land should be replaced with corn parable land. Response: Discussions are under way with the County on the use of its land to develop a drainage anti trail corridor between the RTC site and the Mississippi River. The new Appendix J shows that tlne drainage infiltration featured noted as 26b in Figure 12.4 no longer extends into tim Mississippi Regional Park. However, a pipe connection from 26b to the River remains a part of the drainage concept, provided this route is approved by the County. 'I'he nature of the pipe and the design of the outlet structure at the River are discussed in Appendix J and will be the subject of regulatory review by tine DNR, County and City if and when it occurs. Corn ment 12.11: In Section 12 - Mitigation Impacts Associated with Stormwater Outfall to the Mississippi River, preservation of the river bluff and its natural vegetation is important. The storm water management infl'astructure should strive to minimize distu~'bance to thc natural shoreline of the river. Council staff concurs with the AUAR recommendation ["or use of directional boring techniques in lieu of opemcut construction. P, esponse: The City concurs with the need to protect the River bluff. Please refer to the above comment (# 12.10) response and Appendix J, and the discussion of Critical Area/MNRRA/WSB standards in Item 14. Corn ment 12.12: In Section 14 - Resource Protection Zones, Water Related Management District, if wetland mitigation or stormwater management for fine Town Center project tal<es place on the south side of TH 10 and in the regional park, those activities are within the Mississippi Critical Area and the appropriate rules apply fi'om the City's Critical Area Plan. P, esponse: Please refer to the discussion in Item 14. Co m men t 12.13: [n Section 11 - Fish, Wildlife and Ecologically Sensitive Resourcesl given the extent o[" fine proposed water feature on the site and extent of nearby sandy. uplancl area, the site lmbitat may be even more amenable to amphibians and reptiles in the ["uture than it is now. Tm'tles are known to travel up to a mile from~wetland feeding areas to their upland nesting areas. Council staff recommends requiring the use of 34-25 -173-
