construction. Right -of -entry forms will 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. 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. Protected Turn Lanes: Protected turn lanes were considered at 161st Avenue and at Alpine Drive. At 161st Avenue, the pavement is proposed to be widened to accommodate a pedestrian refuge island. This reduces available right of way for a southbound right turn lane. Furthermore, adding a southbound right turn lane would increase the crossing distance for pedestrians, reducing the benefits of the pedestrian crosswalk improvements. Since the majority of traffic traveling to Central Park, located west of Variolite Street on 161st Avenue, comes from the south, a northbound left turn lane may be warranted and will be explored during final design. Staff feels a northbound left turn lane at 161st Avenue would improve safety, especially for pedestrians, by removing the chance for drivers to use the shoulder to pass vehicles waiting to turn left from the through lane. At Alpine Drive, turn lanes are not proposed to be explored during final design considering the stop condition for Alpine Drive and the low traffic volumes on Alpine Drive and Variolite Street. There is simply not enough vehicle queuing to justify southbound right and/or left turn lanes. 4.3 Stormwater No stormwater retention and/or treatment improvements will be required as a result of this project. This project proposes to replace side street culverts on 8 of the 10 streets which currently have culverts due to the age and conditions of the existing culverts. The 72-inch Trott Brook culvert is full of water and cannot be inspected but is in good condition and is not proposed to be replaced. 4.4 Watermain Improvements This project proposes to extend 12-inch watermain from the end of the existing 16-inch watermain at 166th Avenue north to 173th Avenue as identified in the 2040 Comprehensive Plan. This will allow looping of trunk watermain, and will support future development north of Trott Brook. 4.5 Sanitary Sewer Improvements This project proposes to replace the existing force main sanitary sewer from 163th Avenue to 166th Avenue with 21-inch gravity sanitary sewer as identified in the 2040 Comprehensive Plan. This will provide greater flexibility for future development to the north and west, and will reduce head loss due to friction in the pipe thereby increasing the capacity of the sewer system downstream of the sanitary sewer lift station currently serving the Brookfield development and the new elementary school. Other areas to the north and east could potentially be served by this lift station Feasibility Report Variolite Street Reconstruction City of Ramsey Project No. 20-01 9
