TO: Honorable Mayor and Council Members
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
Police Facility Remodel Project
On March 12th Sequoia
Construction mobilized to the site
and began project work. In the
beginning, the contractor is focusing
on building demolition, and filling
the pool, hot tub, and pool
equipment room with gravel (see
photo inset right).
Over the next month, the contractor
plans to continue demolition
activities, and to install the new
plumbing in the existing floor.
Additionally, the contractor hopes
to have the new concrete floors
poured over the pool area.
Staff are also working on the PG&E application for the project, which is being modified to include a future solar panel interconnection. Additionally, public works and police department staff are working with Silke, the City’s radio communications contractor, to finalize a scope and fee to relocate and upgrade the radio communications infrastructure for the new facility. Staff anticipate bringing a contract with Silke to the Council for approval in April. 2022 Pavement Management Plan Update
In March the 2022 Update to the City’s Pavement Management Plan was completed by the consultant retained by the Humboldt County Association of Governments (HCOAG). In short, while the City’s Pavement Condition Index (PCI) did increase from 63 to 65 over the past fiveyears, the City’s deferred maintenance liability did as well. Based on the analysis performed by the consultant, the City’s existing deferred maintenance liability is $24.2 Million, and the average annual funding amount required to maintain the City’s existing road condition (PCI of 65) is $2.73 Consent Item 4g
Million over the next 10-years. Staff plan to present the findings and implications of the report in detail at a coming council meeting.
Water Tank Coating Project
Since approval of the project at the March 6th Council meeting, staff have been working on contracting and bonding with the contractor. Staff anticipate being under contract within the next week. The City’s engineering consultant GHD, who is acting as the construction manager for the project, is working to set up a pre-construction meeting, and currently staff believe that the contractor will mobilize to Fortuna in late April or early May.
Concurrently, public works staff are working to develop a temporary water storage plan, as each tank will be taken off line during construction. Also, staff are working on flyers and other messaging for a voluntary citizen water use reduction plan during construction, as the available water storage within the City will be reduced while the main tanks are taken offline for the project. 12th Street LID Project
Bids will be opened for the project on March 16, and staff anticipate bringing this item to the Council for an award recommendation in April if bids come back within budget. Currently, the engineers estimate for the project matches the construction budget available. Should bids come in higher than the available budget, staff will have to consider additional funding sources, which could include additional grant funding from the state as they have indicated some additional capacity for gap funding.
Corp Yard Generator, Corp Yard Roof, and Percolation Pond Project Staff is currently working on contracting, bonding, and insurance for each of these projects. Staff anticipate that each of these projects should being in April or May.
Utilities Division- Utility Lead
Service Call Summary
In the month of February the utilities division completed 103 service calls by operators.
Figure 1 below shows the distribution of service calls by type. Underground Service Alert (USA) has changed their format and the Utilities crew can no longer track how many mark and locates have been completed. There were zero missmarks, resulting in zero broken utilities.

In the month of February the utilities crew changed out 22 dead water meters. Continued to check service lines for lead.
Continued to perform regulatory backflow testing.
In February the City had two water leaks. There was an estimated water loss of 18,045 gallons.
The crew repaired the hydrant hit on Redwood Way at Rohnerville Road. The estimated water loss for this is 37,800 gallons.
Rebuilt 15 water meters to put back into the system. Also finally received 30 new water meters.
Repaired hydrant burry that was damaged on Mathew Lane.

Wastewater Collections System
Utilities cleaned 20,000 feet of sewer main.
Repaired 22 feet of sewer lateral on St Joseph Dr. that was hit by an underground boring crew (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:
Staff assisted Engineering with measuring the
depths of sewer pipes at various manholes
throughout the City. Consultant engineers
needed field verification for the Sewer
System Model and Master Plan CIP project.
(See photo inset right).
Staff spent significant time during this past
month troubleshooting wastewater treatment
plant problems, including poor pump
performance from a heat exchanger
recirculation pump, and similar pump issues
on one of the two plant sump pumps. Staff
also tackled an electrical control problem at
the Headworks stair-screen press unit.
Staff removed one of the three primary
clarifiers from service due to poor sludge
pump performance and a rising sludge blanket. In the process of cleaning the clarifier, staff discovered a dislodged rubber wheel in the opening of the pump sump inlet pipe. This wheel had fallen off the scum skimmer device on the clarifier’s surface. Staff returned the unit to service upon removing the obstruction.
Staff compiled and submitted compost samples to contract laboratories for analysis. Once results come back clear, staff hope to announce a free compost giveaway to the community in mid-March.

Staff completed final preparations on multiple shafts, sprockets and drive-chain to re-install in the grit channel. Staff had removed this equipment last year after a catastrophic failure.
Supply lead times and weather-related delays prolonged the time-line of this project, but staff plan to finalize it in March.
The Utilities crew assisted staff with cleaning out the wet-well at the Strongs Creek lift station. This regular preventive maintenance task is required to remove grease, trash, and other solids buildup that can harm the pumps at the station.

Tesla and PG&E contractors conducted functionality testing on the battery power system at the water wells site (Corrosion Control Facility) this past month. This was the next-tolast step in the process before commissioning of the energy storage device. Once the unit is given permission to operate, it will provide electricity to the site during times of peak energy demand on the grid. Plans are to finalize this process within a month.
General Services and Streets - General Services Superintendent The following is a list of scheduled assignments completed by the General Services staff in February:
