Landscape and trail restoration is proposed to begin in early January, weather allowing. Paving work on Palmer Ave. will need to happen in spring 2021. For the interim, winter paving will be cold patch over the existing sewer trench. Contractor will also complete the remaining 4” service connections at that time to minimize the amount of cold patch that will need to be in place through winter.

November 6, 2020

Work has been progressing on the Fort Tuthill Utility Improvement Project, with this week’s work expanding on the work mentioned last week.

 

Two crews continue to work on the project. Crew 2 has been making good progress between Mt. Dell and Purple Sage Rd. and will cross Purple Sage Rd. next week, weather allowing. Crew 1 is working through Mt. Dell on Palmer Ave. Where the trench is deep, they are working around rock and clay/unsuitable material and the going is slow.

 

Pavement submittals have been received and the Contractor is proposing a two-phased paving operation in light of the slow going in Palmer Ave. First paving will occur at the eastern end of Mt. Dell Rd. while Crew 1 continues to install sewer main on Palmer Ave. The 2nd phase of paving is proposed to happen a week or two later once Crew 1 completes work on Palmer and moves to the west out of the paved road and into an unpaved road section.
