. Executive Summary As part of its Subregional Growth Study, the North Metro 1-35W Corridor Coalition analyzed the impacts of land use and develop- ment patterns on the transportation system that serve the subre- gion. The results of the analysis informs development of a set of subregional strategies that address common concerns regarding transportation, housing, and economic development in the corridor. Two subregional growth scenarios were analyzed. One scenario fol- lowed conventional suburban development pattems; the other scenario applied transit-oriented development principles, which emphasizes waIkable, mixed-use centers and multi-modal transportation. In this report, the transit-oriented scenario is referred to as the "Coalition growth scenario." Both scenarios met or exceeded Metropolitan Coun- cil subregional job and household growth projections for 2020 as pub- lished in 2001. . Transportation impacts of the two growth scenarios were analyzed with a subarea transportation model designed to function within the regional transportation model. The subarea model provided the level of detail necessary to make findings relevant to individual com- munities while maintaining integrity at the regional level. For both scenarios, the transportation baseline included assumptions based on current policy documents and roads planned to serve major de- velopment or redevelopment in Arden Hills, Blaine, and Roseville. For the second run of the model, additional roadway network was added to increase connectivity within the Coalition and transit ser- vice was enhanced. Findings of the analysis conclude that both growth scenarios in- crease congestion on the regional highway segments and the minor arterial network within the corridor. This finding is not a surprise. National studies indicate that the Minneapolis-St. Paul region is ex- periencing a higher rate of congestion growth than most other re- gions in the county. It stands to reason that adding new growth in any form would only exacerbate this condition. e The question then becomes, does one growth scenario have ad- vantages over the other? Overall the Coalition growth scenario shows a more efficient pattern of tripmaking. Efficiency is gained by re- ducing the length of trips within the Coalition, increasing the num- ber of walking trips, and increasing the number of transit trips. Mixed-use centers appear to playa significant role in realizing this efficiency because they offer a better jobs Ihousing balance, create more opportunities to walk or bike, and generate densities suffi- cient to warrant high levels of transit service. The reduction in ve- hicle miles traveled and slowed growth rate in trip generation, which are associated with the Coalition growth scenario, implies addi- tional benefits for the environment and quality of life.
