If unsuitable material is encountered beneath the existing pavement during construction, it will be removed and replaced with suitable backfill material. Any sod that is damaged as a result of the project will be replaced. In order to match the new street, driveway approaches will be removed between the existing pavement and approximately the property line. A four foot (4') concrete apron will be constructed behind the curb, and the remainder of the removed portion of the driveway will be replaced in-kind with asphalt or concrete. During construction, City staff will work with those property owners who wish to make driveway improvements. The cost of any private driveway improvements is the property owner's responsibility. The PCls of the streets under consideration are not as low as others in the City, however, reconstruction is being proposed at this time for the following reasons. The soil borings indicate that the existing structure of the street is inadequate. Roseville's project would stop mid-block, therefore, this project is also being proposed to provide continuity in this section of the neighborhood and limit the inconvenience of construction to one season. With Lake Johanna nearby, the need to address water quality issues with storm sewer improvements also adds to the need for this project. Street design At our neighborhood meeting in December, the residents were comfortable with the width and design that is being proposed along the Roseville section of the streets. The type of curb and gutter proposed is S5 I 8 curb, which has a lower back and is a type of surmountable curb. Existing street grades will be altered where appropriate to address drainage. EXISTING UTILITY CONDITIONS Public utilities located within the proposed project areas include City water, storm sewer, and sanitary sewer. Private utilities include Xcel gas and electric, telephone, and cable TV.
