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
Over the past month, the contractor has spent the majority of the time framing the interior of the building, and completing the southern ‘half’ of the new building addition area. See the photo of the first concrete pour of the
addition inset right. To date, the
majority of the rough framing
has been completed, in addition
to the plumbing. In the coming
month, staff anticipate the
contractor will work on
completing the ‘north’ portion
of the building addition, and
complete new exterior wall
framing.
As stated in last month’s report,
the construction contingency
fund has been required due to a
number of unforeseen issues,
and over this past month that
trend has remained the same. To date approximately 25% of the initial contingency amount remains, or about $100,000. Staff do believe that the majority of the unknown issues have been addressed, however, there remain a number of items that will require use of contingency, including contractor work for the new PG&E and AT&T services, and the installation of solar panels. It is likely that some additional contingency funding may be necessary depending on the true costs of these items, or if other unforeseen circumstances arise.
Rohner Park Basketball Court Project
The contractor completed the grading and paving in mid-May. On June 13th, the subcontractor that will be completing the acrylic surfacing will be onsite to inspect the finished paving surface to Consent Item 4g
determine if it is suitable for finished striping and coating. The same subcontractor plans to mobilize to complete the coating work the week of the 4th of July. There will likely be some overlap between project work and Rodeo week, however, staff are working closely with the contractor to ensure that the site will be secure and disturbances/conflicts will be minimized to the extent possible. Prior to the coating contractor, Humboldt Fence will be onsite to install most of the site fencing, and City crews will work to fill the planters with soil. The project is anticipated to be fully completed by July 14th.
Corp Yard Roofing Project
The roof at the corp. yard is near completion, and all aspects of the project are anticipated to be complete before the end of the fiscal year. During the project, only minimal unforeseen building damage was found, all of which was fixed by the contractor onsite. Overall, the project is anticipated to be completed under-budget.
Water Tank Coating Project
The City’s contractor began work on May 22nd at the Hillside tank site. So far, the work at that site is ahead of schedule, and staff anticipate the contractor will be moving to the Campton tank site in the last week of June. To date no construction contingency has been required.

Wastewater Events & Maintenance Tasks Completed:
Contractors completed annual
rehabilitation work on the percolation
ponds. Staff switched effluent
discharge from Strongs Creek to the
ponds well before the May 15
deadline, as regulated by the State
Water Resources Control Board.
A Fortuna High School class toured
the plant. About 30 students and their
instructor learned how the City treats
its wastewater and how it is recycled
for crucial resources. (See photo inset
right).
Staff began work on re-installing new shafts, sprockets, and other equipment in the grit channel. Staff removed this equipment a year ago due to a failure. Supply chain issues, long lead times, parts-preparation, and waiting for flows to subside prolonged this project until now.

Water Events & Maintenance Tasks Completed:
PG&E granted the Tesla battery-pack installation permission-to-operate at the water wells site. This unit will save electricity during times of peak energy demand, and thus save the City utility costs.
Colburn Electric completed construction and installation on the emergency generator at the Drake Hill booster pump station. The last step before automatic activation of the generator is for Tesco Controls to re-program the radio telemetry unit. This should occur sometime in the next month or so.
Sub One Diving completed tank cleaning and inspection of the City’s 2 million gallon, concrete Stewart Tank. The American Water Works Association recommends this task every 5-7 years. The tank was in excellent working condition and staff do not anticipate cleaning and inspection of this facility for another 5-7 years. 0 0.5

Wendt Construction assisted staff in reinstalling the rehabilitated, 125 HP motor for booster pump #2 at the water wells
site. Industrial Electric repaired this
motor after its fault a few months ago.
Bringing this pump online adds crucial
redundancy for water production. (See
photo inset right).
Logging contractors completed log
removal and chip grinding at the City’s
Vancil Reservoir. City staff will utilize
the piled wood chips for future compost
operations at the wastewater treatment
plant.
City staff completed work at Hillside
tank: site-grading; connecting,
disinfecting and activating three 10,000-
gallon temporary storage tanks. Staff drained the 250,000-gallon steel tank just in time for the arrival of the coating contractors’ mid-month. The contractors started sandblasting the interior of the tank towards the end of the month. Plans are to have both the interior and exterior sandblasted and re-coated by mid-to-late June. City staff began preparation-work at Campton Heights tank. Staff will need to plumb in eight, 10,000-gallon temporary storage tanks to use while contractors sandblast and re-coat the interior and exterior of the one million gallon, steel tank. This work will occur in July.
