The reconstructed roadway would consist of two 12 foot travel lanes with an 8 foot <br />parking lane on the west side of the street. On the east side parking would be restricted <br />and a two foot curb buffer distance would be placed between the edge of the travel lane <br />and the face of the curb. Figure 2 illustrates both the existing street profile and the <br />proposed reconstructed street sections. <br />The street project would begin just south of 140th Avenue which is the point at which <br />new pavement from the Bunker Lake Blvd project terminates. The width of the pavement <br />would taper at both ends of the project until reaching the 34 foot wide section illustrated <br />in figure 2. <br />Curb chokers will be placed on the west side of the street at all intersections north of <br />140th Avenue. Chokers narrow down the street width by extending the curb into the <br />parking lane. The narrower street width tends to slow traffic speed and contributes to <br />increased pedestrian safety by reducing the crossing distance. Approximately 60 on-street <br />parking spaces would remain along the west side of the street after allowing for driveway <br />cuts and chokers. Boulevard trees would be installed on both sides of the street at 35 foot <br />intervals and street lights would be placed at each of the six intersections. In addition one <br />light would be placed mid block between 140th Avenue and 141st Lane and two more <br />between 143`d Avenue and CSAH 5. This light spacing would provide uniform lighting <br />along the entire length of Dysprosium Street. <br />Existing catch basins shall be relocated to accommodate the narrowed width of the street. <br />In addition, storm sewer will be extended approximately 400 feet south of the catch <br />basins located south of 141St Ave as is illustrated in Figure 3. This area has a flat grade <br />and the additional drainage will extend pavement durability. This drainage modification <br />will require street grade changes will allow steep driveways in this area to be flattened. <br />This project will reconnect each existing driveway opening to the newly paved street. <br />Five common driveways serve ten single family lots on the west side of Dysprosium <br />between 142nd Circle and 143~d Avenue. These property owners will be contacted and <br />given the option of having a individual driveway installed to their property. Both <br />property owners of the common driveway must agree to being assessed the additional <br />cost of driveway reconstruction beyond the sidewalk. The driveway approaches <br />between the street curb and sidewalk shall be replaced with concrete at a standard width <br />of 25 feet. The driveway pavement beyond the sidewalk shall be neatly sawed and <br />replaced with the same paving material. The width shall be tapered to match smoothly <br />into the existing driveway. Restoration shall include the protection or repair of any <br />irrigation systems or invisible fence. Mail boxes may be relocated to accommodate <br />construction but shall be returned to their original locations upon termination of the <br />project. Disturbed turf areas shall be restored with topsoil and sod. <br />ESTIMATED COSTS <br />Page 3 <br />
