Construction in and around the roundabout is really coming along nicely. The big takeaways this week:

  • If you’ve driven around it recently, you’ll see that the circle is being constructed as well as decorative stone walls. The stone wall within the circle will be several feet high and tie into the landscaping within the circle.
  • Starting the week of May 7, a subcontractor will place lithocrete, an architectural concrete with embedded recycled materials, on South Healdsburg Avenue. This along with cobbles placed in the center circle will be used to delineate the flow and direction of Foss Creek. This decorative cobble feature is also porous, which will help cut the amount of storm water run-off.

Here are several photos, taken yesterday, of the stone walls in progress as well as of the circle.
