Comprehensive Plan Amendment Village of Hardwood Creek page 11 The AUAR recognizes the importance of managing access to major transportation infrastructure. Collector and arterial roads will not function well if new road intersections and driveways are allowed without an overall plan. The AUAR follows access management guidelines with'/ mile spacing between full intersections on 20th Ave. The development site does not abut Main St. The pictured collector road would need to extend 1/4 mile south of the site to access Main St. The Centerville /Lino Lakes border complicates the situation, as does the undetermined interchange design. The location of the access to Main St. is still under consideration. Main St. is challenging because of the I -35E interchange planning underway among Lino Lakes, Anoka County, Centerville, and MnDOT. The current front runner for the interchange design includes a typical diamond with one exception. In the northwest quadrant of the interchange, the southbound exit ramp forms a new intersection and continues onto a new local road south of Main St. (see attached figure). This new local road would run between the existing 2151 Ave. and I -35E. The new signalized intersection on Main St. would be only about 600 feet from 215` Ave. The latest plan is to convert the 21" Ave. intersection to limit turning movements and allow westbound Main St. traffic to flow freely from the exit ramp to 20th Ave. The 20th Ave. intersection will be signalized. All this means that the location of 21' Ave. north of Main St. is an important consideration. The road design does not need finalization as part of the comprehensive plan amendment approval. However, the road design must fulfill the traffic needs. A traffic study has resulted in a recommendation that running a new road from Main St. north to the Hardwood Creek development on the west side of the existing bank and would be an acceptable alternative. This road would provide access to the north. However, there are a number of considerations that will need to be addressed with site design: enough stacking distance and the level of service near the interchange, Anoka County's view of access in the area, including spacing of signalized intersections, access to properties within Centerville, and water and sanitary sewer trunk alignment to serve the project. The new road might end up being a right in/right out only, with primary access to the site from 20th Ave. It could also end up aligning with the existing 215t Ave. These questions will apply whether or not the comprehensive plan is amended and no matter how the site is developed. The point is that there are alternatives for creating accesses to the site. The details will have to be worked out at part of the PUD review. 3) General Location and Extent of Public and Common Open Space. The concept plan includes an extensive open space network. The open space is to include stormwater management features, parkland, and trails combined into a large greenway system.
