EXECUTIVE SUMMARY:
Public Works Director/City Engineer
Police Facility Remodel Project
The project was awarded to Sequoia Construction Specialties at the February 6th Council meeting.
Since that time, staff have been working on contracting and bonding with Sequoia, and engaging our project design team to finalize construction drawings per the changes to the project that resulted from the bid period addendums. Staff are anticipating that the contractor will mobilize to the site in early March. The police are working on bringing their operations back to City Hall, and they anticipate having the site fully vacated by the end of February.
In early February, staff conducted a meeting with Pacific Gas and Electric (PGE) at the site to determine how to upgrade the electrical service for the new police facility. PGE indicated that power will be available for the project, and currently the timeline to install the required improvements is in line with the proposed project construction schedule. PGE’s next step is to begin design for the project.
Staff have also been working with Silke Communications, who will be the dispatch radio upgrade contractor for the project. Staff anticipate finalizing a scope and budget for this portion of the project sometime in February, and plan to bring to the Council in March a Public Interest Finding for a contractor sole source with Silke Communications.
Water Tank Coating Project
In January, the City opened bids for the Hillside and Campton Water Tank Coating project. The City received four bids, with the low bidder being Simpson Sandblasting & Special Coatings out of Fontana. The low bid amount is approximately $870,000. Staff plan to bring the award recommendation for the contract to the Council, in addition to a Supplemental Budget request to recommend adding the necessary budget for the project, to the first meeting in March. 12th Street Low Impact Development (LID) Stormdrain Project Staff have been working with the City’s consultant engineers to finalize the design for the 12th Street LID stormdrain project, which will include raingardens and new stormdrain pipe along 12th Consent Item 4g
Street in between Loni Drive and K Street. The project is anticipated to be put out for construction bidding in mid-February.
As noted in a previous monthly report, during the design process staff found that portions of the new utility undergrounding project on 12th Street were installed in conflict with the proposed stormdrain pipe, specifically near the intersection of 12th and K Streets. Staff have been working with the utility providers to correct the conflicts in time for the City’s contractor to begin work, which is anticipated to begin in June of this year.
Utilities Division- Utility Lead
Service Call Summary
In January the utilities division completed 116 service calls by operators. Figure 1 below shows the distribution of service calls by type.
Underground Service Alert (USA) has changed their format and it no longer allows for tracking of how many mark and locates have been completed. There were zero miss-marks, resulting in zero broken utilities.

Water Distribution System
Read water meters and complete meter worksheet.
In the month of January the utilities team changed out 19 dead water meters. Continued to check service lines for lead.
Performed regulatory water system backflow testing.
In January, there was one water leak and one hit fire hydrant, see Table 1 below. The utilities division is still unable to get water meters due to supply shortages and staff spent five full days rebuilding and testing meters to replace dead meters in the system. 0 10

Wastewater Collections System
Utilities cleaned 15,000 feet of sewer main.
There was one sanitary sewer plug on St Joseph Street that backed up multiple times into a business. The utilities division televised the line and found that a communications line had had been installed which broke the sewer line. The utilities division repaired the sewer line and is working on site restoration.
Miscellaneous Tasks
The utilities division performed monthly maintenance on the division’s heavy equipment, including greasing and checking all fluids.
Alex Garza started his career with the City of Fortuna on the utilities crew as a Utilities II.
Water Treatment/Wastewater Division- Chief Plant Operator Storm Flow Response: Significant rainfall occurred during the first two weeks of the month. This rapidly increased wastewater flow into the treatment plant in the form of inflow and infiltration (I&I). This I&I flow was also most likely exacerbated by numerous potential sewer main breaks caused by the late December earthquake. Staff managed to operate and maintain the system through various process adjustments, succeeding in treating the increased flow without any effluent violations or sanitary sewer overflows (SSOs).
Division Staffing: Senior Wastewater Treatment Plant (WWTP) Division staff conducted interviews this month for a vacant Operator-in-Training position. One of the prospective applicants will be offered the position in early February.
City Projects: This past month saw progress on two, significant WWTP Division projects: City staff hosted the pre-bid walk for the annual percolation ponds rehabilitation project at the WWTP; and the bids were finalized and opened for the Hillside and Campton Heights tanks re-coating project. This latter item will be presented to City Council in March.

Staff spent a great deal of time cleaning and organizing in the WWTP garage building.
Decades of clutter were sifted through to free up significant space. Staff finalized and submitted major reports to State and Federal agencies this month including the 2022 Annual Wastewater Report, Volumetric report, and the Annual Biosolids report.
A professional service technician from the manufacturer of the WWTP belt filter press— BDP—visited the plant to assist in troubleshooting this important solids dewatering device.
Staff worked alongside the technician for training, and also replaced worn roller bearings and both pressure-side belts.
