EXECUTIVE SUMMARY:
Public Works Director/City Engineer
Public works staff have been engaged in a number of ongoing projects, see the summary below:
Citywide Water Conservation Measures
As presented at the June 6th Council Meeting, effective on June 10th the City of Fortuna will be enacting Stage 2 of the City’s Water Shortage Contingency Plan (WSCP). This is a mandatory requirement by the State, and is being prompted by State Execute Order N-7-22, which also passed a vote with the State Legislator on May 25, 2022. Enactment of State 2 of the WSCP is not a result of supply issues with the City of Fortuna’s water system and well field. The Measures that are in effect under Stage 2 of the City’s WSCP include:
No use of a hose without a shutoff nozzle (to prevent water waste when hose not in use) No use of non-recirculatory fountains or water features No washing sidewalks, driveways, parking areas, or tennis courts or other exterior paved ways unless by a public agency for the purposes of public safety Outdoor irrigation days for ornamental landscapes or turf will be Saturday, Sunday, Tuesday, and Thursdays. Outdoor irrigation for gardens or other non-ornamental landscapes are permitted on all days
The application of potable water to outdoor landscapes in a manner that causes excessive runoff onto non-intended areas is prohibited
A primary component of implementing the water conservation stage is public outreach. Leading up to June 10th, staff prepared and gave a presentation to the public at the June 6th Council meeting, developed a water conservation flyer, and developed a webpage on the City’s website (https://www.friendlyfortuna.com/departments/public_works/water___wastewater_departments/ water/water_conservation.php)

The City regularly measures depth to groundwater in the City’s water wells, and as shown in the graph in the Chief Plant Operators report, water levels are generally consistent with previous years, wet or dry. Staff will continue to measure and assess groundwater levels as the summer month’s progress, and report on the status of the aquifer.
12th Street Interchange Modernization Project
Staff have been working with Caltrans and HCOAG to complete the funding allocation paperwork for the California Transportation Commission. Early indications from Caltrans was that the allocation process may be simplified, however, it appears this assessment was incorrect and that there will need to be additional paperwork and agreements prior to beginning actual project work.
At this point, staff anticipate taking a professional services award recommendation to the Council at the second meeting in July, and beginning design work on the project sometime later in 2022. 12th Street Prop 1 Integrated Stormwater Enhancement Project Staff have executed the professional services agreement with the City’s consulting City engineer and have begun planning pre-design field investigation activities. The City worked with Fortuna Union High School staff to finalize the memorandum of understanding pertaining to the Low Impact Development (LID) basin located on the high school property.
Campton and Hillside Water Tank Coating Project
The City is awaiting a tank cleaning a dive inspection of the two steel water tanks prior to developing the final project plans. The dive inspection is anticipated to take place in June.
Kenmar and Drake Hill Water Pump Station Emergency Stationary Generators The project was awarded to Robert Colburn Electric at the June 6th council meeting. Currently, staff are working on contracting, bonding, and insurance with the contractor, and anticipate issuing the Notice to Proceed in mid-June. The first order of work on the project will be for the contractor to order the generators.
Caltrans Active Transportation Program Grant for John Campbell Trail During May, staff worked on a grant application to the Caltrans Active Transportation Grant Program (ATP) for Phase 1 and 2 of the John Campbell Memorial Trail. The proposed project in the grant would include the trail in between the River Lodge and Redwood Way, and include some other minor sidewalk infills along Redwood Way and Fortuna Boulevard. The grant application will be submitted on June 15th. Staff anticipated hearing back on the grant later in 2022.

Water Distribution System
The utilities team installed one new service to the system in the month of May. In May there was four water leaks resulting in an estimated 40,500 gallons of water loss, one leak being a major main break on 9th street. Table 1 below shows a summary of water leaks and losses in May.
In the month of May the utilities team changed out 12 dead water meters.
The utilities team helped parks with the removal of the old rubber chips and install of the new wood chips in the tot lot.
The utilities team dug up 35 feet of water main on Newell drive to see if it was leaking as there was a lot of water running out of the hillside. It was determined to be ground water, see the photo inset right.
Utilities team paved water ditches.

Water Treatment/Wastewater Division- Chief Plant Operator Tesla Corrosion Control Facility Battery Project: Tesla contractors continued installation on the battery units at the City’s water wells site. The contractors added in the stairs and railing to the elevated pad. City staff will soon work with Tesla on commissioning the units before PG&E can permit them to operate.
WWTP Tour: Plant staff conducted a tour of the Wastewater Treatment Plant for local Cub Scouts and their families.
California Drought: Staff worked on completing an Annual Water Supply and Demand Assessment for the State Department of Water Resources. This important and newly required report details projected water demands and supplies for the next year. The report showed that the effects of drought on the City’s water supply are not apparent, and that there is far more than enough supply in the Eel River Valley groundwater table to meet the demands of the City. 5/13/22 1100 9th Street 4’’ A.C. 50 2 Hours 6,000

System Inspections:
The County Division of Environmental Health
inspected the water and wastewater treatment
facilities to assess the storage and handling of
hazardous materials. The County found most items
in compliance, with only the need for a required
update to the City’s Risk Management Plan
documents.
The State Water Resources Control Board Division
of Drinking Water conducted a Sanitary Survey of
the water system (see photo inset right). This
inspection occurs every 3 years and is required to
ensure that the City’s water infrastructure is in
compliance and meeting all safety standards.
