The roadway network, including Otter Lake Road and the other supporting streets, will provide local and regional access for this 400 acre portion of the city. The planned roadway network will accommodate the orderly development of the existing and anticipated commercial properties north of Main Street. The area adjacent to the proposed Otter Lake Road just north of Main Street (CSAH 14) is currently experiencing development pressure. A supplemental Traffic Study was completed for this area to determine the appropriate local street network. A copy of the South Otter Lake Road Study is included in the Appendix of this Master Plan. Traffic forecasts were prepared for the 2040 conditions assuming full build of the anticipated land use for the area. Based on the traffic projections the Otter Lake Road extension will have a daily volume of 14,800 vehicles per day (vpd) at Main Street (CSAH 14) and 9,000 vpd to the north. A portion of the existing traffic on 24th Avenue will be redistributed to the Otter Lake Road extension. Reviewing the city of Lino Lakes and city of Hugo Transportation Plans, approximately 40% of the existing traffic could be redistributed. The attached figure on the right shows the projected 2040 average daily traffic (ADT) volumes on the local roadway network assuming that Otter Lake Road at Rosemary Way is restricted to a right-in/right-out. The roadway design will be based on City design guidelines and MnDOT State Aid Standards. The roadway will consist of a two-lane cross section with left and right turn lanes at the primary access locations in a 120ft right of way corridor. The first intersection on Otter Lake Road north of Main Street (CSAH 14) at Rosemary Way will be converted to a right-in/right-out access. The first full movement access would be located approximately 660ft north of Main Street (CSAH 14) providing access to the planned commercial and retail land uses. The intersection will be controlled with either a roundabout or traffic signal. The remaining intersections to the north would be spaced approximately 1/4 apart with side street stop control. A pedestrian path will be included on the east side of the roadway extending the path adjacent to the existing Otter Lake Road from Main Street (CSAH 14) to Rosemary Way. The trail will connect the Regional Trail on Main Street (CSAH 14) to the neighborhoods to the north. A sidewalk will also be provided on the west side of Otter Lake Road. Rosemary Way is proposed to be extended from Otter Lake Road to 24th Avenue, serving as a backage road to Main Street. A connecting road from Rosemary Avenue to the full movement access on Otter Lake Road will be required. The exact alignment of this route will be determined as the area develops. Otter Lake Road Master Plan Rosemary Way at 24th Avenue currently is stop controlled for the Rosemary Way approaches. As the area develops the level of service at the intersection will start to cause a backup past the existing Kwik Trip access road. The future intersection operations will likely warrant intersection control improvements such as northbound and southbound left turn lanes on 24th Avenue with all-way stop control or a traffic signal or a possible roundabout. These improvements will be coordinated with the City of Hugo.
