Eli <br /> ks. .= F1k River cmvelMmmgnmrim <br /> River <br /> should be <br /> at least 330 <br /> feet <br /> • The City of Elk River should develop its own spacing guidelines for local roadways within the <br /> study area to ensure mobility and safety on its facilities. <br /> • The supporting roadway network should be continuous where possible so that local trips can <br /> avoid having to access US 169 in the study area. <br /> • Intersection control will be determined as growth and development occur. Adequate space at <br /> proposed roadway intersections should be preserved to accommodate future traffic signals <br /> and/or roundabouts. <br /> • Right of way along city, county and state facilities should be acquired or preserved in order to <br /> ensure that adequate capacity can be provided for in the future, including opportunities for <br /> pedestrians and bicyclists. As plats for development are submitted, the full right of way area <br /> should be noted, not just the amount of right of way needed at the time of the parcel's <br /> development. <br /> Figure 21 shows the proposed roadway network needed to accommodate the Phase 1 and 2 planned <br /> land uses, as well as those that would be needed beyond the 2040 timeline. As this area develops, it will <br /> be important to include infrastructure for pedestrian and recreational bicycle movement by including <br /> trail on one or both sides of each roadway.This translates into the following for right of way <br /> preservation: <br /> • Urban 2-Lane Roadway: 75 feet minimum. This allows for two travel lanes, turn lanes in both <br /> directions at intersections, shoulders (including curb), a boulevard and a trail on one side of the <br /> roadway. Assumes an eight-foot boulevard and a 10-foot trail. Accommodates between 8,000— <br /> 10,000 cars a day. <br /> • Urban 3-Lane Roadway: 100 feet minimum. This allows for two travel lanes, a center turn lane, <br /> shoulders (including curb), a boulevard and a trail on one side of the roadway. Assumes an <br /> eight-foot boulevard and a 10-foot trail. Accommodates between 15,000—18,000 cars a day. <br /> • Urban 4-Lane Divided Roadway: 120 feet minimum. This allows for four travel lanes, left-and <br /> right-turn lanes at intersections, center median, shoulders (including curb), a boulevard and a <br /> trail on both sides of the roadway. Assumes an eight-foot boulevard and a 10-foot trail. <br /> Accommodates 28,000—32,000 cars a day. <br /> • Urban 6-Lane Divided Roadway: 150 feet minimum. This allows for six travel lanes, left-and <br /> right-turn lanes at intersections, center median, shoulders (including curb), a boulevard and a <br /> 39 <br />
