Mr. Timothy 1. Nelson -6- December 3, 1996 TRAFFIC ANALYSES PERFORMED TO DATE AND THEIR ADEQUACY IN MEETING FUTURE TRAFFIC NEEDS The previously referenced report prepared by Barton-Aschman Associates in September 1989 includes a detailed traffic analysis. Table 3 on page 25 of this report indicates that the planned development in the Twin Lakes Business Park would generate a total of5,6I5 trips in the p.m. peak hour and 58,185 trips per day. This table also presents trip generation projections for four other planned nearby developments: Byerly's, Center Pointe, NMI.10pus, and Rosewood. As presented in Table 3, those four developments would add an additional 6,400 trips in the p.m. peak hour and 44,730 trips per day. This September 1989 Barton-Aschman report indicates that County Road C and Cleveland Avenue would experience major traffic impacts due to the planned Twin Lakes development and would need major upgrading. Item 6 on page 48 of that report presents the following statement: "Basically the street and highway system serving the Cleveland/Snelling study area is inadequate to accommodate projected year 2000 traffic. County Road C will need significant modification throughout its entire length ftom Cleveland to Snelling Avenue and Cleveland Avenue between County Road C and the 1- 35W ramps immediately north of County Road C need significant upgrading." Clarification is provided on page 40 of the report regarding the types of improvements needed. Item I on this page makes the following statements regarding County Road C: "County Road C will take the primary impact of the projected traffic increase when full development is achieved. Basically, County Road C should consist of three through lanes operating in each direction. An additional left-turn lane for eastbound and right turn and westbound at Cleveland will be required. An additional right-turn lane for eastbound at Fairview is also desirable. The additional through lane for eastbound can be established as a right-turn lane at Snelling Avenue." Item 2 on page 40 makes the following statements regarding Cleveland Avenue: "The section of Cleveland Avenue north of the I-35W ramps between County Road D and C-2 will be adequate as proposed in the Centre Pointe Study namely with two through lanes in each direction and a fifth lane provided to accommodate left turns in both directions. However, Cleveland Avenue between the I-35W ramp intersection and County Road C should consist of two through lanes, two left-turn lanes and a ftee right-turn lane for southbound and two through lanes with two left-turn lanes for northbound." The significance of the preceding traffic impacts determined, by Barton-Aschman was further corrobated in correspondence that was submitted by Metropolitan Council staff soon after completion of the Barton-Aschman study. In a letter dated September 28, 1989, to Rick Jopke of the City ofRoseville, Steve Keefe of the Metropolitan Council states, "We have detemUned that the proposed amendment presents a potential impact on the metropolitan system plans, specifically on the metropolitan transportation system." In a subsequent letter tg. Rick Jopke dated February 21, 1990, Steven Schwanke of the Metropolitan Council indicated that the City and Metropolitan Council staff agreed that the City would complete a traffic study that would include seven components. The letter further states that this traffic study was to be submitted to the Council no later than April 1, 1990.
