8 inch deep reclamation of the existing bituminous pavement and placing 4-inches of aggregate base class 5 or reclaim material, and 3.5-inches of new bituminous pavement. The subgrade discovered was lean clay and it is noted additional work may be required, especially if this material gets wet when exposed. City Staff is in close agreement and propose allowing full -depth reclamation material as an option for the contractor, placing 4-inches of aggregate base class 5 or reclaim material, and 3.5-inches of new bituminous pavement. 2-feet of lean clay subgrade will be removed and replaced with 2-feet of select granular borrow material. The proposed improvements should have a service life of approximately 60-years, assuming maintenance such as overlays, crack sealing and seal coating is routinely performed. 4.1.4 Other Considerations Driveways: Existing driveway aprons may need to be reconstructed to varying degrees. The limits of construction will vary with each driveway apron based on the elevation of the street abutting the driveway and the driveway pavement type. During design, Staff will evaluate the construction limits for each driveway 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 will be obtained from private property owners where work is required outside City right-of-ways and easements. Irrigation Systems: Developed properties along the project corridor may have private irrigation systems. Staff will notify property owners of pending construction as far in advance as practical to allow them time to move their irrigation systems out of harm's way before work begins Parking Restrictions: Parking is currently provided along both sides of the streets and is not currently restricted except for overnight parking per City code. During this project, parking will be restricted during allowable working hours. Pavement Corings: Existing pavement thicknesses have been found to be inconsistent throughout the City. It is now standard practice to have City Staff on -site during pavement installation to insure the proper quantities are being placed. As further conformation, Staff is proposing to collect GPR data or to have pavement corings taken at the conclusion of all 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 projects. 4.2 Stormwater Treatment Feasibility Report Ford Brook Estates Street Reconstructions City of Ramsey Project No. 19-01 10
