City Council Legacy at Woods Edge March 8, 2004 apply to the I -35W /Lake Drive and I -35E /Main Street interchanges. However, the ordinance does require examination of development impacts and a plan to resolve identified deficiencies. The City's engineering consultant SEH has completed a traffic analysis for the site to evaluate traffic impacts both internally and extemally of the site. A summary of the traffic analysis prepared by SEH, dated February 11, 2004 is attached. As part of the study AM and PM Peak Hour trip generation rates were developed for the proposed development as well as the existing facilities (City Hall complex, Fairview Clinic, and Lino Lakes State Bank). Trips to /from each building have been assigned to the street system within the development. This provided a tabulation of traffic volumes at various locations within the development, as well as at the intersection of Town Center Parkway and Lake Drive (CSAH 23). According to this analysis, the Peak Hour traffic volume is 1,155 trips, which occurs from 4:30 -5:30 p.m. Based on the traffic analysis, a concept transportation improvement plan was developed for the Town Center Parkway and Lake Drive intersection. On Town Center Parkway, the plan includes three outbound lanes to separate left turn, through, and right turning traffic and also includes two inbound lanes. Signalization of this intersection would also be necessary to maintain acceptable levels of service. According to the 2020 Traffic Volume Forecast in the Lino Lakes Transportation Plan, traffic volumes on Lake Drive are anticipated to increase to over 17,000 trips per day. Regardless of the proposed development, improvements to Lake Drive are expected in the future. However, to accommodate the full development of the Legacy at Woods Edge Development, several additional improvements to Lake Drive will need to be made in the short term. The concept transportation plan has proposed the construction of two southbound left turn lanes between the intersection of Town Center Parkway and the I -35W bridge. Furthermore, traffic signals at Town Center Parkway and both ramps to I -35W are anticipated. To signalize the south ramp intersection, the existing off ramp and on ramp intersections, which are now separated, need to be aligned to a single intersection, which would require the reconstruction of approximately 400 -feet of the on ramp. A meeting was held on January 29, 2004 with the Mn /DOT Area Engineer and Mn /DOT traffic and freeway modeling staff to review the analysis. Mn /DOT indicated that no further analysis was required. However, the Federal Highway Administration (FHWA) has requested documentation that demonstrates traffic will not back up onto mainline I- 35W. As detailed in the attached traffic operations analysis the I -35W /Lake Drive interchange area will perform at acceptable levels of service (LOS D or higher) through 2010 with the proposed improvements. The analysis also demonstrates that queue lengths (the distance of vehicle stacking at intersections) will not back onto the I -35W mainline.
