ssessments for existing City bridges are necessary to identify maintenance and repair needs. Professional engineering, geotechnical and environmental assessments are necessary when initial observations and inspections identify deficiencies. Some recent inspections have seen increases in deterioration of existing embankments and sl
opes supporting the bridges' foundations. Accurate study of existing conditions and recom
mendations for short and long-term remediation are the first anticipated outcomes of this project.
In the last several years City engineering has identified needed repairs at various bridges including systems for engineered slope protection, erosion control and drainage. This project will allow for formal condition assessments for specific bridge systems that have been identified to have a potential concern.
A local emergency was declared due to concerning erosion of the banks at the abutments. Temporary measures to stabilize the banks were designed and installed over the winter. A detailed bridge assessment of creek bank stability and the bridge's drainage system is necessary to design and construct the bridge repairs.
The project is needed to repair and maintain this City owned bridge.

The City's Corporation Yard serves as the backbone for a diverse range of City services. Multiple departments have operational divisions based at the site, i.e. Public Works, Utilities, Parks and Recreation, and IT. Current site layout has developed organically with little long-term planning to guide building locations, vehicle and personnel circulation routes, workforce requirements, and generally make efficient use of the site to continue serving the Napa community for the foreseeable future.
Additionally, the City recently re-occupied the portion of the site previously used by NVTA as their bus yard, and proper planning to bring this area into the workflow of the site is needed.
This generator is the oldest the City currently has in its inventory. It is critical that this generator be operational when needed. Replacement of generators can take months and it is prudent that the City proactively replace this key piece of equipment prior to failure due to long lead times for procurement.

The Public Art Steering Committee prioritized asphalt artwork to elevate and enhance the area. This project will enhance the intersection aesthics and create art on the pavement. Traffic engineering studies have found that pavement art can result in traffic calming.
This is an innovative project that will deliver public art and result in traffic calming along Main Street.
Built in 1918, the Tulocay Creek Bridge is a historic landmark in the City of Napa and a replacement project is set to commence in 2026. The City will work with Caltrans to extract and store approximately 24 cubic yards of original stones for use in a public art project.

Description
Justification
This
major composting infrastructure improvement would expand and extent the useful life of the first CASP (Covered Aerated Static Pile) active compost system at the MDF. The first CASP 1.0 system (build in 2018/2019 and fully operational in 2020) was constructed on the northeast corner of the MDF property and utilized positive aeration of mixed compostable organic material (i.e., food scraps, manure, grape pumace, soilded paper and yard trimmings) for first 22 days of active composting. The proposed CASP 2.0 system would be installed on the northwest portion of MDF property (when current compost curing and concrete/asphalt processing currently occur) utilizing a negative aeration system to become the primary aeration system for first 22 days of active composting process. After installation of CASP
2.0, CASP 1.0 on northeast portion of the MDF property would then be repurposed for curing of compost product and reduce the current curing time (with no aeration) from 40 days to the 25 days (for a total estimated composting duration reduced from current 63-days to 47 days).
As more food scraps and other volatile organic compound emitting organics have been introduced to Napa’s collection and processing system (for added landfill diversion and as required by SB 1383 state law), the original CASP 1.0 composting system became necessary to comply with increasingly stringent regulations for air emissions, stormwater management and in compliance with solid waste facility permitting governing the MDF. Particularly for air permit/air emission requirements, CASP 2.0 is needed to provide negative aeration treatment (i.e., air being “sucked” through active compost materials vs. positive aeration system employed by CASP 1.0). The first 22 days is of composting raw organic material has the highest potential for air emissions and thus require a higher level of treatment and control that a negative aeration system provides. The combined ability of CASP 2.0 as the primary treatment for first 22 days and CASP 1.0 as the secondary treatment for following 22 days, will shorten the total processing time by 25% (from 63 days to 47 days) which is vital for Napa’s MDF as space is a premium while state regulations (and the City’s own climate change and policy goals) strive to capture more and more organic materials for composting onsite at the City’s MDF.

Currently, staff manages and tracks the condition, location, age, potential for failure, cost to replace and record of work performed on these assets.
The City cannot maximize service delivery and effectively communicate with the public in a timely manner without an effective means to manage its portfolio of assets. The alternative is to continue using a reactive asset management approach (i.e. fix it after it reaches the point of failure) versus a proactive and/or predictive asset management approach (i.e. understand failure modes and attempt to allocate resources appropriately before failure occurs).
The City could continue managing non-standardized information in discrete silos resulting in information gaps between departments, less informed business decisions, and less efficient transfer of information throughout the organization and to the public.

Description
Justification
Replace 8,000
feet of 36-inch Asbestos Cement pipeline on Foothill and Foster Rd from St Frances Circle in the south to Laurel in the north.
The existing pipeline is a component of the water system's primary transmission pipeline network and is similar to nearby pipelines that have exhibited multiple leaks and have created damage to roadways and adjacent private properties. Replacement of this line will increase reliability of flow through the center of the distribution system, facilitating management of water tank levels, meeting customer water demands, and sustaining reliable water supply for fire suppression requirements.

Storag
e tank cleaning removes sediment that builds up over time and affects the quality of the water being delivered. Every 15-20 years, water storage tanks require new coating to offset the destructive elements of corrosion and tank wall deterioration. A tank coating that is in poor condition reduces the life of the tank.
The water system contains many steel storage tanks, some of which require new coat
ings as part of a periodic tank coating program. A durable tank coating with clean in
terior walls aids in the delivery of high-quality water, increases the life of the tank and helps decrease maintenance costs to combat the effects of corrosion.

xcavate, inspect and replace transmission main valves or install new operators as part of an annual valve replacement program.
This project is necessary to maintain and rehabilitate existing transmission main valves. Specifically, one-time purchases for parts and labor will be expended to extend the life of existing valves (15 years or more).
Pum
p Station Improvements include repair and replacement of facility and equipment com
ponents to be completed by City staff or Contractor as recommended by the water utility's master plan or by staff.
The water distribution system connects treatment plants, storage tanks and pump stations across 5 pressure zones. Pump stations provide necessary pressure and fire protection to higher-elevation zones. Some improvements address system flow and pressure deficiencies identified by the master plan, while others provide improvements to meet new safety and regulatory requirements.

oject # 63WT30UT01
Useful Life 100 years
Category Water Transmission
Description
Justification
Replace 5,300
feet of 36-inch asbestos-cement transmission pipeline with 36-inch steel pipeline from the Napa River at Soscol Ferry Rd to Sheehy Ct. About 650 feet of this project is on/near Soscol Ferry Rd, located near the Napa Sanitation District headquarters. The pipeline traverses a swampy undeveloped area east of Napasan to the west end of Sheehy Ct, where it connects to a steel pipeline installed in 2023.
This transmission pipeline is critical to the water system and within the last several years has exhibited failures in swampy areas that are difficult to access, making repairs costly and lengthy, increasing the risk involved in such events. This upgrade, in association with a related project that will establish more secure access in coordination with PG&E and the Napa Sanitation District, will secure a critical infrastructure asset for many years to come.

n October 8, 2017, the Atlas Fire began as one of fourteen large fires that burned simultaneously across eight Northern California counties. The Atlas Fire caused extensive damage to several City-owned facilities, among them being the Milliken Raw Water Pipeline. This Hazard Mitigation will involve burying and/or otherwise protecting this critical pipeline from future fire, landslide and rock/tree fall damage, and will include replacing or lining most or all of the pipeline.
The City's treatment plant is located over one mile from the intake at the water supply. The raw water pipeline conveys raw water from the City's diversion dam to the Milliken Treatment Plant. The treatment plant cannot be operated unless the raw water pipeline is in service.
