EXECUTIVE SUMMARY:
Public Works Director/City Engineer
Police Facility Remodel Project
The project continues to progress on schedule, and weather permitting, the project is anticipated to be completed in March of 2024. Over the past two months, the contractor has continued to complete outside work, including installing most of the new concrete, installing the gas line, and installing the pad, panels, and conduit for the new power service. Staff anticipates the power service being installed and active sometime in January. On the inside of the building, drywall, texture, and painting have been completed, in addition to the rough in electric, plumbing, and HVAC. The next orders of work on the inside include acoustic ceiling, doors, and casework. 12th Street Stormwater Project
The project has been substantially completed, with paving having taken place in mid-November.
The final remaining item of work is the striping, which is currently scheduled for December 13th or 14th (weather permitting). Since the return of the rains, staff have worked through several issues identified in the original project design, most notably at the northeast corner of 12th and K Street, in front of Bob’s Footlong. The initial project design did not appropriately manage the amount of storm-drain runoff entering the basin, and on several occasions, there was localized flooding at the intersection. Staff worked with the contractor to add drainage inlet in the area which has since been able to manage the drainage demand. Another issue was the mulch used in the basins. As noted below in the General Services staff report, the initial placement of redwood mulch was found to be problematic under high-runoff conditions, and therefore staff substituted rock for all basins along 12th Street. These two modifications have notably improved the performance of the basins, and staff believe that the project is now operating consistently with the intent of the design.
Chief Plant Operator Resignation
As the Council was made aware at the December 4th meeting Chris Christianson, the City’s Chief Wastewater Plant Operator (CPO), has accepted a position with the Shelter Cove Resort Improvement District. The City is currently recruiting for a new CPO and in the interim Andy Bowles, the shift supervisor, will be serving as interim CPO.

Wastewater Collections System
Utilities cleaned 10,000 feet of sewer main.
We had one sewer plug in the month of October that spilled approximately 50 gallons of sewer into a field. The cause of this SSO was due to a large amount of roots grown into a manhole and the surrounding pipe, and a large amount of baby wipes. Dug up a suspected sink hole over the sewer line at 1505 Main St, found no issues with the pipe or connections.
Miscellaneous Tasks

This completes the FEMA grant-funded emergency generator project, which also includes a stationary, emergency generator at the Drake Hill booster pump station.
Contractors installed a new, updated cathodic protection system unit at the Campton Heights water storage tank (see photo inset right). This important system prevents corrosion of the steel, which is especially important after the recently completed tank re-coating project. The original system was vintage with the tank (circa 1989) and required an update.
Staff worked on hauling ground-up wood waste from the Vancil reservoir site down to the WWTP to use in compost operations.
Logging contractors had left this byproduct material at the site upon completion of their recent operation there.
