The work on the water-line tie-ins on North and South Healdsburg Avenue and East Mill is going so well that we don’t need to shut off water for merchants on North Healdsburg Avenue, as earlier projected. We verified an inline water valve just north of the North Healdsburg tie-in location and due to its location, we don’t need to shut off water. The North Healdsburg tie-in work will be done next Wednesday during regular business hours.
In addition, yesterday (Jan. 11), we tied in the water line on East Mill. We temporarily stopped water for a few hours for Spoke Folk, who were notified earlier of this stoppage. Next Tuesday is the water tie-in work for South Healdsburg Avenue, which is estimated to take about an hour.
City staff dropped by businesses who will be affected, including Parish Café and Singletree, and asked GHD and Bay Cities to start the work as early as 7 a.m. to avoid too much disruption to merchants.
Underground utility work on West Mill to begin Jan. 15: Parallel with roundabout construction, Staggs Construction (contractor) will dig next week (January 15-19) near the driveway entrance to the businesses on West Mill for utility improvements called for in the Underground Utility District (UUD) project. This work was initially scheduled for this week, but rain put this work on hold.
The UUD project removes overhead electric and telecommunications utilities along Healdsburg Avenue and Mill Street. This operation will be in the street/sidewalk area and should not impact vehicular access to these businesses, which have already been notified of this work. In the event of rain, this work may be delayed until we get better weather conditions.
January 17 BAG meeting: The next business-advisory group (BAG) meeting is next Wednesday, January 17, at 9 a.m. It will be held at the Chamber of Commerce, 217 Healdsburg Ave.

Abandonment of Old Sewer Utilities
- Bay Cities prepared the old sewer lines for abandonment now that the new sewer lines have been installed. This was scheduled for last week, but rain delayed this work.
