Comprehensive Plan Amendment Village of Hardwood Creek page 11 acreage. Some rough estimating, which includes open space and right of way data for the residential area only, leads to a residential density about 4.5 units per acre. 2) General Location of Major Streets and Pedestrian Ways. The concept plan includes the main collectors and access points envisioned in the draft AUAR (see attached Figure 21 -1 from AUAR).. A local north/south collector provides a route through the site. Two collector roads provide access to 20th Ave. on the west of the site. The north/south collector would continue south to access Main St., and north to future developments. The concept plan also shows an internal local circulation network providing access for the residential development areas. 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 V2 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 undeteimined 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 21' Ave. and I -35E. The new signalized intersection on Main St. would be only about 600 feet from 21" Ave. The latest plan is to convert the 21" Ave. intersection to limit tuming 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 21" Ave.
