This report serves as an updated traffic analysis for the Twin Cities Army Ammunition Plant (TCAAP) Alternative Urban Areawide Review (AUAR) which was originally completed in 2014. The traffic analysis was not updated as part of the 2019 AUAR Update. The TCAAP site is located east of US Highway 10 and north of Ramsey County State Aid Highway (CSAH) 96 in the City of Arden Hills, Minnesota. The development is known as Rice Creek Commons and is anticipated to include a variety of residential and commercial land uses. The location of the development is provided in Exhibit 1. The forthcoming traffic analysis focused on two analysis years: the existing conditions (2024), and a long term date (2040) which will demonstrate the effects of the fully completed development on the adjacent roadway system with future growth. No interim period is included in this analysis. 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 for 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).
