DRAFT November 21, 1995 Assumptions were used through the process that led to development of the plan. Because • of the distant horizon and the assumptions made in virtually every step of the process, it is imperative that the assumptions be reviewed periodically for their continued validity as the City grows. When necessary, adjustments should be made to the plan recommendations. It is important to recognize that the form and condition of a transportation system can drive land development, but also that land development can cause changes in a transportation system. Therefore, development proposals should be checked for consistency with the transportation plan, and likewise the plan should be adjusted as necessary to remain representative of land use conditions in the City. The proposed ultimate functional classification system for the City of Elk River, minus future residential collectors in areas still to develop, is shown in Figure 8. Included are the proposed roadway additions described in the previous section. The main focus of this system is to develop a City-wide minor arterial network that provides adequate area coverage and enough traffic moving capacity to handle vehicular traffic in an ultimate development scenario. As mentioned earlier in the report, roadway additions alone will not solve the anticipated capacity problems. In the previous section, many roadway and intersection improvements were identified. The recommended improvements all progress toward the creation of a functional classification system whose roadway designs and traffic control are consistent with the characteristics in Table 4 of this report. Following is a summary of the most critical existing roadway segments and intersections, • and recommended improvements: Roadway Recommended Improvement T.H. 10 from Upland Avenue - Remove intersections to T.H. 169 - Frontage road on south side - Coordinate traffic signals - Additional thru lane each direction - Upgrade T.H. 10/T.H. 169 interchange - Roadway additions, especially bypass to T.H. 169 Proctor Avenue from County Road 1 - Channelization improvements to T.H. 10 - New and revised traffic signals, coordinated - Consolidate or eliminate access points - Roadway additions, especially westerly extension of Highland Avenue and T.H. 10/T.H. 169 bypass School Street from Proctor Avenue - Add thru lanes, turn lanes • to Jackson Avenue - New traffic signals at Proctor - Roadway additions which remove traffic from this route CTP-230.156 -17- 230-156-80
