RCM 10408.01 <br /> PROPOSED IMPROVEMENTS <br /> A. Streets <br /> Proposed improvements for the streets in the project area include complete reconstruction of the roadway. <br /> Reconstruction of the roadway will include removal of the existing bituminous pavement and concrete curb and <br /> gutter,excavation of the subgrade soils,and placement of granular subbase,aggregate base,new concrete curbing <br /> and bituminous pavement. The proposed pavement section is shown on Figure 2. The proposed roadway will <br /> be the same width as the existing roadways and will match the existing alignment and grade as closely as <br /> possible. By matching the existing roadway,the disturbance to adjacentproperties will be minimized. <br /> The proposed pavement section is based on available soils data from earlier projects. The subgrade soils in other <br /> projects were found to be mainly sandy lean clays and some clayey sands. With these soil types we have assumed <br /> an R-value of 10 to 12 and a 7-ton pavement design. The pavement design will be confirmed after the soils <br /> investigation has been performed during the design phase. The proposed pavement section also utilizes a <br /> ' geotextile fabric to act as a material separator. This prevents the underlying moist clays from penetrating the <br /> granular subbase. <br /> The proposed pavement section incorporates a 6-inch diameter dram file on each side of the street beneath the <br /> ' curb and gutter. The drain tile will remove any water which accumulates in the granular road subbase,thereby <br /> reducing the potential for future frost heave action. The drain the will be located in the areas of existing and <br /> proposed storm sewer. Drain tile in the Roosevelt and Edward Street segments is proposed to connected with <br /> additional tile to existing storm sewer in 34th Avenue between Edward and Harding Streets.At such time as 34th <br /> Avenue is redone and additional storm sewer installed this the would be connected to the reconstructed 34th <br /> ' Avenue system. <br /> Boulevard areas which are disturbed during construction will be restored with sod. Trees and shrubs which are <br /> near the roadway will be protected and saved wherever practical. Trees or shrubs which are removed will be <br /> ' replaced with a similar variety but smaller size. Driveways will also be restored to their pre-construction <br /> condition wherever they are disturbed <br /> B. Watermain <br /> All of the watermains in the project area are proposed to be replaced with 6,8 or 10-inch diameter ductile iron <br /> pipe. The new watermain will be installed alongside of the old watermain. The old watermain will be plugged <br /> 5 <br /> 1 <br />
