Executive Summary:
Hood Mountain Regional Park and Open Space Preserve (Park) is a dramatic park preserving 3,500 acres of rugged wildlands for wildlife connectivity, conservation, and public recreation. The Nuns Fire in 2017 and the Glass Fire in 2020 burned through the park destroying park infrastructure including culverts, storage tanks, historical buildings, a bridge, retaining walls, and killing thousands of trees. The Hood Mountain Pythian Water Tank Replacement Project (Project) replaces ruined water storage tanks, restoring non-potable water storage for firefighting and for one park residence and one neighboring property.
Construction includes:
• Demolition and removal of three ruined redwood water storage tanks and replacement with one large fire-resilient corrugated steel water tank.
• Replacement of the temporary waterline with a permanent water supply line.
• Felling of one large dead fir tree in the construction area.
Regional Parks is requesting the Board approve the plans and specifications for the Project and recommends awarding the contract for construction to Coastside Concrete & Construction, Inc. in the amount of $374,500.
Discussion:
Hood Mountain Regional Park and Open Space Preserve is the largest county park and has become increasingly popular as a wilderness destination within 10 minutes of Santa Rosa. The Park burned during the 2017 and 2020 wildfires, causing damaging to park infrastructure, roads, and trails. The Nuns Fire severely burned nearly half of the park, and in 2020 the Glass Fire raged through burning nearly 80% of the park. The redwood water storage tanks were utilized by fire crews in 2017 to fight fire and save park residences. Three years later, these water tanks were damaged beyond repair by the Glass Fire.
The Project consists of replacing the three damaged and ruined redwood water storage tanks with one large, fire resilient galvanized steel water tank at the same location, thereby replacing water storage capacity. The water is intended for firefighting and non-potable uses at one park residence and one neighboring property. The neighboring property has an easement for non-potable water uses. Though the home on this property was lost in the 2020 fire and has not been replaced, this project will maintain the neighbor’s access to water per a recorded agreement.
The original waterline from a spring box to the water tanks was damaged in one of many post-fire landslides. The waterline ran along, and about 20 feet downhill of, the top of the steep 80 to 100-foot-deep creek bank. When the bank failed, it caused a break in the pipe. A temporary waterline was installed along the top of the bank because the bank was too steep to access the pipe for repair. This project will move the temporary waterline to a permanent uphill location aligned within a park road. The project will also remove a large fir tree killed in the fire which is a hazard to contractor crews, trail users, and the new water tank.
The contract work includes demolition, earthwork, constructing an improved tank pad, assembling one 30,000-gallon water tank onsite, trenching and installing 2-inch water supply pipeline, felling of one large dead-and-standing fir tree, implementing erosion control, restoring disturbed areas, and all related work as indicated on the plans.
Staff recommends the Board approve the plans and specifications for the Hood Mountain Water Tank Replacement Project, award the bid for the Project to Coastside Concrete & Construction, Inc. in the amount of $374,500 for a contract term of 200 working days, authorize the County Executive Officer or designee to execute the contract, and authorize the Director of Regional Parks or designee to make as needed minor changes to the project required by the final condition, agency approvals, and other project conditions so long as the total does not exceed 15% of the total project cost. If this contingency is exercised, total contract amount would be up to $430,675 ($374,500 + 15%). The total estimated project cost for construction and construction management is $455,000.
