Kimley-Horn was retained to prepare a Traffic Impact Analysis (TIA) for the Northwest Main Street development in Lino Lakes, Minnesota, as the site undergoes the Alternative Urban Areawide Review (AUAR) process. The site is located along Main Street (on both sides of the street) between the city limits and 41h Avenue. An aerial view of the study location and surrounding roadway network is presented in Exhibit 1. As part of this study, the existing roadway network was analyzed to determine the current operations at the study intersections. In order to assess the potential impact of the development scenarios on the area roadway network, site -generated trips were established and added to the background traffic volumes. Background traffic volumes included the other major development projects in the vicinity. Future traffic conditions were evaluated for the approximate Opening Year of the proposed development (2030) and a long-term "Design Year" (2045). Background conditions were analyzed for each study year, along with the "build" conditions of the two development scenarios. Additionally, an Existing (2025) conditions traffic analysis was conducted. This report presents and documents data collection, summarizes the evaluation of existing and projected future traffic conditions on the surrounding roadways, and identifies recommendations to address the potential impact of site -generated traffic on the adjacent roadway network. 1.1. REPORT PURPOSE AND OBJECTIVES The purpose of this study is to address traffic and transportation impacts of the proposed development on surrounding streets and intersections. This traffic impact study was prepared based on criteria set forth by the AUAR guidelines. The following specific information, per AUAR recommended content, should be provided: • A description and map of the existing and proposed roadway system, including state, regional, and local roads to be affected by the development of the AUAR area. This information should include existing and proposed roadway capacities and existing and projected background (i.e. without the AUAR development) traffic volumes; • Trip generation data - trip generation rates and trip totals - for each major development scenario broken down by land use zones and/or other relevant subdivisions of the area. The projected distributions onto the roadway system must be included, • Analysis of impacts of the traffic generated by the AUAR area on the roadway system, including: comparison of peak period total flows to capacities and analysis of Level of Service and delay times at critical points (if any); • A discussion of structural and non-structural improvements and traffic management measures that are proposed to mitigate problems. Note: in the above analyses the geographical scope must extend outward as far as the traffic to be generated would have a significant effect on the roadway system and traffic measurements and projections should include peak days and peak hours, or other appropriate measures related to identifying congestion problems, as well as ADTs (average daily traffic).
