FROM: Brendan Byrd, Public Works Director/City Engineer SUBJECT: Public Works/Engineering Department Monthly Report STAFF RECOMMENDATION:
Receive report as an informational item.
EXECUTIVE SUMMARY:
Public Works Director/City Engineer
Water Tank Coating Project
Staff worked with our engineering consultants to finalize the project bid package for recoating Campton Heights and Hillside steel water tanks. The project was formally put out to bid on December 12th, and the bid opening is late January. Staff anticipate bringing the project to Council for award in early February.
Police Facility Remodel Project
The final design drawings were completed in October and the project was put out to bid on October 31st. On November 16th, staff conducted a mandatory pre-bid meeting at the future police facility site to provide contractors the opportunity to see the site and familiarize themselves with the requirements of the contract. The meeting was attended by 15 contractors, and staff feel confident that many local building contractors are interested in submitting bids for the project.
The initial bid opening date was December 1st, however, due to the number of questions that have been submitted by contractors staff have extended the bid period to December 21st at 2 pm. Over the past month, staff, with assistance from the City’s engineering consultants, have issued five bid addendums addressing over 75 questions received from contractors.
In November, staff submitted an application for electrical service upgrades to PG&E for the project. This is an item that is commonly completed by the General Contractor, however, in this case staff are hoping that an application submitted sooner will help to ensure PG&E engagement earlier on in the project. At this time PG&E has not indicated that there will be significant hurdles in the service connection upgrade for this project, but staff will continue to track that closely with PG&E staff.
If the bid opening date does not require further extension, staff anticipate bringing the project and the bid results to the Council in January.

Vancil Reservoir Rehabilitation Project
To date, all trees have been fallen and removed from the site, and there has been sufficient windows of good weather to complete operations onsite. The City’s General Services and Wastewater crews worked hard during the logging operation to keep the access roads and drainage systems functioning to expedite the contractors logging operation. Remaining items of work onsite include cleanup, chipping, and contractor demobilization.
Kenmar Interchange Improvement Project
The final draft initial study and mitigated negative declaration (CEQA document) for the Kenmar Interchange Improvement project has been completed and was circulated in early December. The document will be available for public comment through the beginning of January. Staff anticipate bringing the document to the Council for approval in early February.
Sanitary Sewer Master Plan and Stormwater Infrastructure Vulnerability Assessment Currently the City has a consultant working on Stormdrain and Sanitary Sewer Master Plans, to help guide and inform the City’s capital improvement program in the coming years. In the last month, the City’s consultant has worked to develop the engineering models used to assess the system for overall performance, and City staff participated in workshops to inform the design team of operation and maintenance considerations our public works crews are aware of. These master plan projects will be ongoing efforts throughout most of 2023.
Rohner Park Basketball Court Project
The Council approved the award of a construction contract to Mercer Fraser at the December 5th meeting. Since that time, staff have been working on contracting with Mercer Fraser. Staff anticipate having an update on the project construction schedule in January.
Corporation Yard Roofing Project
Staff have been working on developing a project bid package to replace the metal roof at the City’s corporation yard at 190 Dinsmore Drive. The project bid package was finalized and posted on December 12th, and staff anticipate bringing the project to the Council in early February for an award recommendation. Staff anticipate this project going to construction in late spring or early summer.
Corporation Yard Stationary Generator Project
Earlier this year the City received a USDA grant to add a stationary emergency generator and automatic transfer switch at the City’s corporation yard. Currently, the facility has no backup power during outages, and staff manually connect a small portable generator to keep the phone and internet systems active at the site during a power outage. The USDA grant will cover approximately 50% of the total project cost. In November, staff worked to develop a bid package, and the project was put out to bid in early December. The bid opening is in January, and staff anticipate bringing this item to the Council for contract award in January or February.

Figure 1. Utility division service calls by type in November.
Water Distribution System
Read water meters and completed meter worksheet.
The utilities team installed one new service to the system in the month of November. In November there were no water leaks, but had one hydrant hit resulting in an estimated 24,000 gallons of water lost.
In the month of November the utilities team changed out eight dead water meters. Continued to check service lines for lead in accordance with EPA requirements. Backflow Testing.
The City has had a difficult time getting water meters so the utilities crew has been rebuilding meters in-house and testing the rebuilt meters afterwards to confirm accuracy.
We have had an 87% success rate rebuilding meters for reuse, and each rebuilt meter saves cost for the City and our ratepayers.
Wastewater Collections System
The utilities team didn’t televise any sewer mains this month as we are short staffed. We now have almost a full crew and will be continuing this effort next month. 0 5

The utilities team had no sewer plugs in the month of November with no overflows. Utilities cleaned 15,000 feet of sewer
main. With no leaks this month we
spent a lot of time on sewer
maintenance. Being proactive on this
helped with having no backups.
Installed one new sewer connection at
508 12th St. that was about 70 feet
long (see photo inset right).
Miscellaneous Tasks
The utilities division performed
monthly maintenance on the
division’s heavy equipment,
including greasing and checking all
fluids.

Wastewater Events & Maintenance Tasks Completed:
The plant hosted a sludge dewatering demonstration
trailer from Process Wastewater Technologies, Inc.
Outside operators and engineers visited the plant to
witness the unit’s potential.
A contractor installed a new gate at the Laurelwood
sewer lift station. This will provide access to the rear of the station for servicing storm drain piping.
Staff removed a fallen tree near the Administration
Building at the wastewater plant.
A contractor replaced some badly corroded gas piping
and fittings on the wastewater treatment plant boiler.
(See photo inset right).
Staff rebuilt various wastewater plant pumps,
including a return activated sludge pump and a heat
exchanger recirculation pump.
Staff used a VacCon truck to pump out numerous City sewer lift station wet-wells of grease and sediment, including rags and “flushable” wet-wipes. A contractor conducted the annual service and maintenance on all chemical gas feed and leak detection equipment (including at the water wells Corrosion Control Facility). Staff also replaced some key process solution valves at the same time. Staff placed the third primary clarifier online as seasonal rains began. Winter-time flows are higher and require more plant volume for proper treatment. As flows continue to increase, staff will bring more standby basins online to meet demand. Staff cleaned out the headworks bio filter of old wood-chip media in preparation to replace the media and rehabilitate the unit.
