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
Work on the police facility remodel project has
continued through the last month, with the
contractor working each day during that time. To
date the majority of the building demolition is
complete, including all walls and wall finishing’s,
ceilings, flooring, and utilities. Two other primary
focuses of the contractor over the past few weeks
have been prepping the pool room for the new
concrete floor, and installing new plumbing, in the
existing concrete floor (see photos inset right). By
the end of the week of April 10th, staff anticipates
having the pool and hot-tub room completely
covered in new concrete.
While the contractor has been working, staff’s
efforts have focused on construction management
and inspection. Staff have been working through
various submittals and contractor requests for
information, in addition to documenting daily
construction activities and guiding design
revisions.
In addition to construction management, staff
have also been working closely with Police
Department staff on the radio communications upgrades required for the project, and have worked with AT&T and PG&E on service applications. Lastly, staff also submitted a supplemental application with PG&E that would allow the City to install solar panels on the facility under the outgoing NEM2 rate structure, which when installed could result in significant electrical usage savings at the facility in the long-term.

Water Tank Coating Project
Staff finalized contracting and bonding with the contractor in early April, and participated in a preconstruction meeting. Staff anticipate the contractor mobilizing to Fortuna in late April or early May to being work. In preparation, City public works staff have been prepping the sites for the contractor, most notably by preparing for the temporary water tanks that will be used while the primary tanks are being taken offline for coating.
12th Street LID Project
Staff opened bids for the project on March 16th. The City received four bids, with the apparent low bid submitted by RAO Construction. The bids came in above the established project grant budget, and since then staff have been working with the State Water Board (granting agency) to seek gap funding. Fortunately, there appear to be excess funds available, and staff are optimistic that the City will be able to obtain the additional grant funding necessary to award the project at the first meeting in May.
Kenmar and 12th Street Interchange Projects
In March staff brought the project environmental document to the council for adoption. Since that meeting, staff have been working to finalize outstanding items on the project report, with the assistance from our consulting engineers. Staff anticipate that the majority of the City-led work on this phase of the project will be complete soon, which will leave only the Caltrans Cultural Reporting and NEPA items outstanding. Once the Caltrans items are finalized, the preliminary design phase of the Kenmar project will be complete, and staff will continue to work to seek funding to continue future phases of work.
In early April, staff participated in a conference call with Caltrans Executive Management Staff in order to further present the City’s interchange projects. The goal of the call was to further engage Caltrans in an effort to gain support for the City’s interchange projects. Overall the meeting went well, and staff feel that with the level of project development that City staff have been able to complete to date, the City is positioning itself well for greater interest and participation from the state or other funding agencies.
Rohner Park Basketball Court Project
The project broke ground the week of April 3rd. At the onset, the contractor completed the excavation and base rock placement work, in preparation for pavement the week of April 10th. The contractor’s current construction schedule should have most of the work completed by the end of April or early May, and the only item outstanding could be the striping and acrylic surfacing, which requires consistent dry weather to install.

Wastewater Events & Maintenance Tasks Completed
Multiple storms this past month required staff to respond to dramatic increases of wastewater system flows and numerous power losses. Overall, the system functioned well.
Staff responded with diligence to all power losses and returned flow from the overflow ponds after each significant rain event to be ready for the next. Staff conducted significant maintenance tasks at the WWTP, including: repairing and replacing sections of the grit sump pump discharge piping and fittings; replacing the headworks backflow prevention device and associated piping; unclogging the headworks screw press discharge piping; and rebuilding the headworks biofilter with new grating, and rock media.

Water Events & Maintenance Tasks Completed
Staff spent significant time on preparing the temporary water tanks and conducting sitework at Hillside and Campton Heights storage tanks. This is crucial and required work before staff can remove these two, large, steel tanks from service for the coating contractors. These temporary tanks will provide water service while the larger tanks undergo their maintenance by the contractors in the near future. Staff worked on over-hauling the emergency generator at Vancil reservoir. PG&E and Tesla performed their inspections and final testing of the battery pack installation at the water wells site on Eel River Drive. This was the last step before PG&E can grant permission-to-operate to the unit. Unfortunately, required upgrades to PG&E infrastructure will postpone this unit’s functioning indefinitely. Staff completed the annual Consumer Confidence Report, and posted this informative water quality document on the City’s website. It will be available at City Hall, or by mail to any customers who request it.
