PRE Tank 4A Tank Replacement Project
The Paradise Ranch Estates Tank 4A Replacement project consists of the design and construction of a 125,000 gallon cast-in-place circular concrete tank to replace the existing aging 50,000 gallon redwood tank and the 25,000 gallon redwood tank destroyed in the Mt. Vision fire in 1995. The project includes additional fire flow storage to satisfy Marin County Fire protection requirements and is consistent with the Board approved 2001 West Marin Long Range Plan. Construction is slated for March – October 2020.
Lynwood Pump Station Motor Control Center
The Lynwood Pump Station is located at the intersection of South Novato Boulevard and Sunset Parkway in the center median. The electrical service and operational controls are over 40 years old and have gone through several temporary repairs over the years. To improve reliability the electrical systems and controls require replacement and relocation out of the flood prone area of the underground vault at the pump station. An above ground electrical control room has been designed to incorporate the historical design of the existing structure and incorporate modern architectural features. The project will include the construction of the new control room and landscaping of the median at the existing pump station location.
Crest Pump Station
The proposed Crest Pump Station project is intended to replace the existing School Road Pump Station, and involves construction of a new building, installation of three 20 horsepower pumps, manifolds, associated equipment and approximately 650 feet of 12-inch diameter and 100 feet of 8-inch diameter pipeline. The new pipeline will draw from zone 1 piping in Bahia Drive and discharge into the Crest system (zone 2) at the end of Cerro Crest. NMWD is working with the City of Novato to procure a small parcel for the project. Construction is projected to commence summer 2021. This project will provide the following benefits:
- Increased efficiency thereby reducing energy costs
- Improved worker safety and access
- Addition of redundant pumping capacity
- Improved fire flow reliability
San Mateo Tank Inlet/Outlet Pipeline
The inlet/outlet project involves installation of a 24-inch diameter main extending from the San Mateo Tank and connecting to existing distribution system piping in San Mateo Way. When San Mateo Tank was originally constructed in the 1960’s, a temporary 12-inch main was also constructed to connect the tank to the distribution system. At that time, additional development was planned along the slopes of Mount Burdell, and the existing 24-inch main in Palmo Way was to be extended to the tank as development occurred. Subsequently in the 1970’s, the Mount Burdell Preserve was purchased by the Marin County Open Space District and no further development occurred. The existing 12-inch main connected to the tank represents a hydraulic bottleneck in the system.
Old Ranch Road Tank No.2
The FY20 and FY21 Capital Improvement Project budgets for Novato include design and construction of the Old Ranch Road Tank No. 2 project. This project consists of the design and construction of a 100,000 gallon welded steel tank to replace the existing aging 50,000 gallon redwood tank, as well as a new access road to the tank. Additional land required for the new tank, water main and access road is being obtained via grant deed and easements from property owners adjacent to the District’s existing tank site. The existing tank will be decommissioned once the new tank has been placed into service. The project includes additional fire flow storage to satisfy Novato Fire protection goals and is consistent with the Board approved 2018 Novato Water Master Plan.
Leveroni Creek Embankment Repair Project
The Leveroni Creek Embankment Repair project is included in the District’s adopted FY 19-20 Capital Improvement Projects Budget. Leveroni Creek’s left bank downstream of the 8-foot diameter culvert outfall plunge pool is slowly eroding, threatening the structural integrity of the Stafford Treatment Plant and Indian Valley Golf Course access road. A similar project was completed in 2012 to protect the right bank of Leveroni Creek near the Stafford Treatment Plant’s centrifuge and reclamation basins across from the current project location. Leveroni Creek provides habitat for steelhead (a federally-listed salmonid) and other species, and the project requires permit approvals from the US Army Corps of Engineers, California Department of Fish and Wildlife, Regional Water Quality Control Board and the County of Marin. Project construction is scheduled for Summer 2021.
Oceana Marin Treatment and Storage Pond Repair Project
The Oceana Marin Treatment and Storage Pond Repair Project proposes to mitigate the impacts of extreme weather and earthquakes on the Oceana Marin Waste Water Treatment and Storage Ponds that occurred as a result of 2016-2017 heavy rains and wind generated waves. Emergency pond berm repairs were performed in 2018 as a temporary solution. The current project entails armoring of the pond berms with stabilization fabric and rock rip rap to provide a long term solution with a high degree of effectiveness. Project construction is scheduled for May – November 2021.
