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