th This item was brought before the City Council on December 8, 2014 for approval. After 35 Council discussion and input from residents in the Twin Lakes Area, the Council determined that 36 the 2007 Traffic Study for the Twin Lakes Area (done in conjunction with the AUAR Update at 37 that time) should be updated to ensure that current background traffic and updates in area 38 development were appropriately represented before approving the design contract. The study was 39 expanded to include an analysis of three scenarios: 40 1: No expansion of Twin Lakes Pkwy and only background traffic growth except for 41 currently approved or proposed development in the Twin Lakes Area 42 2: No expansion of Twin Lakes Pkwy and, background traffic growth and full build land 43 use scenario for Twin Lakes Area 44 3: Expansion of Twin Lakes Pkwy to Fairview Ave, background traffic growth and full 45 build land use scenario for Twin Lakes Area 46 On February 23, 2015, staff along with SRF Consulting Group and Ramsey County, presented 47 the results of the traffic study. Attachment B shows the estimated Average Daily Traffic (ADT) 48 volumes for year 2030 for each scenario. Based on this traffic report the following observations 49 were made regarding the effects of the Twin Lakes Parkway connection to Fairview Ave: 50 Provides an alternative route choice for the Twin Lakes area. With its extension, trips 51 generated within the Twin Lakes area have more travel choice to access the area. 52 Improves operations along the County Road C and County Road D corridors. Vehicles 53 currently traveling along County Road C and/or County Road D have an alternative 54 choice depending on their origin/destination. 55 County Road C/Fairview Avenue intersection: o 56 Under Scenario 2 this intersection is expected to operate at an 57 unacceptable LOS E. Due to right-of-way constraints at the intersection, 58 geometric improvements, such as installation of additional turn lanes, are 59 likely not feasible. 60 Under Scenario 3 (Twin Lakes Parkway extension) this intersection is 61 expected to operate at an acceptable LOS D. 62 In case of an incident or poor weather conditions, when the regional system is o 63 congested, Twin Lakes Parkway could serve as an alternative route, providing 64 relief to County Road C and County Road D. 65 Direct access for developments along Twin Lakes Parkway reduces unnecessary 66 circulation and improves travel time in the study area. 67 The regional travel demand model suggests that few regional trips are expected to use 68 Twin Lakes Parkway. The majority of trips have an origin/destination near the study area. 69 Due to future regional improvements to the surrounding transportation system, o 70 such as the managed lane along I-35W, more vehicles are expected to stay on the 71 regional system rather than use Twin Lakes Parkway as previously expected. 72 There continues to be concern from residents over the connection of Twin Lakes Parkway to 73 Fairview and the impact that it will have on the local neighborhood and traffic volumes 74 particularly on Fairview. Staff feels that the updated traffic study has addressed many of these 75 concerns and shows benefit to the local and regional transportation system as development and 76 redevelopment in the area continues. 77 Page 2 of 3
