WSB also recommended reconstructing only the bituminous pavement. In total, this work is estimated to cost about half as much as a total street reconstruction while resulting in a serviceable pavement design life of at least 30-years. Considering that much or all of the remaining curb and gutter may need to be replaced in 30-years or so, a total street reconstruction could be evaluated at that time. Another benefit to this design is that it would result in minimal impacts to site access and traffic during construction. 4.1.4 Other Considerations Driveways: One or more existing driveways may need to be reconstructed to varying degrees. The limits of construction will vary with each driveway based on the extent of curb and gutter removal and replacement required, the elevations of the street, and the driveway type. During design, staff will evaluate the construction limits for any impacted driveways and will incorporate this into the plans, but as with all street reconstruction projects the exact limits of construction will be determined in the field during construction. Right -of -entry forms would be obtained from private property owners if work is required outside City right-of-ways and easements. Irrigation Systems: Developed properties along the project corridor may have private irrigation systems. Impacts to these systems may occur where the existing curb and gutter is being replaced. On past street reconstruction projects, the City repaired private irrigation systems that were damaged as part of the project. Staff recommends foregoing this practice on future projects. Instead, staff recommends notifying property owners in writing of the pending construction as far in advance of construction as possible to allow them to move their irrigation systems out of the construction area, and then replace it once work is complete. Parking Restrictions: Parking is currently allowed along both sides of the streets except for overnight parking per City code. During this project, parking is proposed to be restricted during allowable working hours also. Pavement Corings: Staff has been finding inconsistent existing pavement thicknesses on existing streets within the City during recent reconstruction projects. It is standard City practice to have staff on -site during pavement installation to insure the proper quantities are being placed. As further conformation, staff is proposing to have pavement corings taken at the conclusion of reconstruction projects. This is already a requirement on all State Aid projects, and will leave more data on the pavement section for future street maintenance proj ects. 4.2 Stormwater Treatment Stormwater retention and/or treatment improvements are not required for this project.
