City Council to Discuss the Next Phase of Miller Avenue Streetscape Project

The Contractor is nearing end of first phase of work of the Miller Avenue Streetscape Project, which has included sewer and storm drain improvements, installation of irrigation and utilities, and improvements to sidewalk, curb, gutter and medians. At their upcoming March 6, 2017 meeting, the City Council will receive a report on upcoming paving work, which is the next phase of construction for the Miller Avenue Streetscape Project. Repaving of the roadway is anticipated to cause disruptions and impacts to the community in regards to traffic congestion, limited vehicle access, detours and noise. As such, the project team is working to minimize impacts and will present a work plan to City Council for community discussion.

Following the City Council meeting, please join us at two informal Open Houses on Thursday, March 9, 2017 at the Miller Avenue construction trailer (near the Civic Parking Lot at the Miller/Evergreen intersection) from 10:30am to 1:30pm and 4:30pm to 6:30pm.

Description of Upcoming Paving Work
The roadway in the Passage, Parkway, and Gateway will receive a paving treatment that involves only the top asphalt layers, called Cold In-place Recycling (CIR). Following the completion of the two processes, the entire street will be paved with a 2 inch final layer of asphalt to provide a uniform surface.

The Main Street area (from Willow to Reed and Valley Circle) involves a more detailed paving process, known as “Full Depth Reclamation” (FDR). Basically, FDR pulverizes up to 18 inches of the underlying roadway, reuses existing ground materials and then overlays with new asphalt. FDR is 50% less expensive than traditional road repair methods, reducing excavation as well as the import and export of materials. The final road will be uniform, have a consistent cross slope, and offer a 20-year design life with regular maintenance. This section of roadway requires such a detailed paving process in order to address elevation changes to improve safety and overcome difficult soil conditions.

Paving Work Plan
Paving will occur on one side of the median at a time (inbound and then outbound), requiring traffic detours around paving work. The project team proposes to safely construct the roadway as quickly as possible to minimize impacts to the community. To accomplish this, FDR repaving work is recommended to take place at night, cutting the work time by 2-3 weeks, minimizing disruption to the community and businesses, and maximizing driveway access. Nighttime paving work is anticipated to take 3-4 weeks to complete. If the paving project is limited to daytime work only, it will take approximately 5-7 weeks.

The City will begin paving work this summer, when school is out and traffic is generally lower in Mill Valley. The proposed night work hours for the FDR paving in Main Street are from 7 pm to 9 am, with the work week beginning Sunday night at 7 pm and extend to Friday morning at 9 am. Other construction work, such as sidewalk repairs and possibly roadway paving in other areas of Miller Avenue will continue on Miller Avenue from 7 am to 7 pm, Monday through Friday. The FDR paving process will create noise mainly generated by the sound of the equipment's engine and milling teeth as they pulverize the asphalt.

At Monday night’s meeting, the City Council will receive an informational presentation and discuss the proposed work plan. The City will also continue its outreach to the residents and businesses on Miller Avenue to inform them of the next phase of the project and anticipated schedule.
