• The wetland restoration for northwest Lino Lakes (the area generally located north of Carl Street and west of 4th Avenue) under the RMP scenario has been used to model the effect of the WPC and conceptual greenway city's greenway system design in addressing downstream volume effects. The plan is shown in Figure 39 in Appendix A. The concept plan increases the viability of development by lowering the water level for the majority of the property while increasing the opportunity for wetland creation, preservation and habitat protection. • The RMP standards modeled for this RMU provide protection for many of the highly susceptible wetlands, but not all. The large area in red on the RMP map (Figure 37 in Appendix A) identifies both upland and wetland. This is an upland /wetland habitat complex, and it is considered a corridor gap area because of fragmentation by existing and planned housing and roads. Fragmentation effects on the habitat functioning should continue to be evaluated and addressed through landscaping strategies, wildlife movement strategies, road design and minimal runoff, and homeowner education. Portions of this gap are included in the city's greenway system shown on Figure 10 -6. Rondeau RMU Existing Conditions Recommendations: • There are large wetlands in the drainage area west of Rondeau Lake that contain plant communities highly susceptible to urban stormwater. Future land use should not use these wetlands for stormwater treatment. Future plans should strive to obtain upland habitat areas around these sensitive wetlands for use as park, volume reduction credit, trails, and stormwater infiltration. Future Neighborhood Park J is proposed to be located in this general vicinity. • Low Impact Development (LID) strategies to maintain recharge and avoid stormwater discharges to Rondeau will need to be employed in any future urban land use. RMP Future Conditions Recommendations: • Stormwater- sensitive wetlands are at risk under current conditions. The City can examine volume reduction practices in the catchments for these sensitive wetlands. Rice Lake RMU Existing Conditions Recommendations: • This subwatershed is a nearly fully developed. Solving resource management problems will thus depend on implementing LID techniques and BMPs. • To the northwest of Rice Lake, three large storm sewer conveyance lines discharge to area wetlands: o One discharges to Rice Lake. The nutrient loading is unknown and if reductions are needed, then partnership with Blaine will be needed. 10 -16 • • •
