Subject Construction of Bridge Street 6160 Tank, Phase 1
AGENDA #
At the past Strategic Planning meeting, Ed Taylor discussed the need for the District to bring a
number of developers together, along with the District in order to construct some of the
upcoming infrastructure projects. More recently, Ed discussed this issue at a Board Meeting in
regards to the area northeast of downtown Truckee.
Figure 1 shows the upcoming projects in this area. The Woodlands project is currently under
development and the Pioneer Commerce Center will likely start within the next two months. The
other projects will likely start construction either this fall or next spring.
The existing water system infrastructure is inadequate to serve these projects. The Water
Master Plan identified that creation of a new pressure zone with a hydraulic grade line of 6160
feet is necessary to serve this area. The proposed service area of this pressure zone is given in
Figure 2. The Master Plan identified the need for a total of 3.6 million gallons of storage in this
pressure zone at buildout conditions. The site for this storage was identified as the 129 acres of
land acquired from Steele Family Partners. A conceptual piping network was also laid out and
is shown on Figure 3.
It is proposed that the 3.6 million gallons storage be provided in two separate tanks located
adjacent to each other. Two tanks at the same site provides the District with a number of
advantages:
1) One tank can be taken out of service for maintenance (painting, cleaning, etc.) while
the other remains in service.
2) During periods of low demand (winter), one tank can be taken out of service to
provide better water quality.
3) Allows for phased construction and would given the District the opportunity to better
match actual system needs.
Ed, Peter and I have been meeting with developers and the School District regarding the
needed infrastructure. The projects shown on Figure 1 have a need for about 2.3 million gallons
of storage upon completion (See attached Table 1).
It is proposed that a 1.5 million gallon tank be constructed as the first phase. A tank of this size
would provide adequate storage for the initial phases of the projects described. The second
tank would likely be required within the next 3 to 5 years, depending on how quickly the projects
reach full buildout. Ed believes that it is in the District's best interest that the District undertake
the design and construction of the tank directly, as opposed having a developer construct the
project. Please note that four existing District customers will be served from this new tank.
Therefore, It is my opinion that the District is responsible for a small portion of the cost of the
storage tank.
The 24-inch pipeline from the tank site to just south of the existing Sanders Well would be
constructed by the developer of the Pioneer Commerce Center. A reimbursement agreement
would be written for this pipeline. The pipe size required for the developer projects is 16-inch
diameter. The rationale for a 24-inch pipeline is to provide the ability to move the water from
four (or more) anticipated wells from the eastern portion of the service area to the western
portion of the service area. It is my opinion that the District is responsible for the additional cost
incurred to upsize the pipeline from 16-inch to 24-inch.
The budget level cost estimate for the storage tank and 24-inch pipeline is given in Table 2.
Recommendation:
• The Board approve the proposal from Sauers Engineering for professional services
related to the storage tank site and the 24-inch pipeline located on District-owned
property. The proposed fee is$84,500.
• 1 anticipate returning to the June 20 Board meeting with a request to Advertise for Bids

,I
ENGINEERING SERVICES
i
Dear Neil:
,this letter is our proposal for professinnal services for the design and construction of the
proposed Bridge Street 6160 Water Storage Tanks. It is my understanding that the pistrict
intends to construct two 1,500,000 gallon(total 3,000,000 galluu) water sturage tali cs at a
District owned nits north of the Nnrthside Well along with approximately 1,000 feel of 24"
pipeline to connect the tank to the distribution syetcm. This project is included in the District's
Water Master plan tlpdate.
Scope of Set-vices
We propose to provide the following services:
I. Euviruumental Review-Based on our experience with similar District projects,we
anticipate that a negative declaration will be the appropriate level of review for the project.
For the construction of the tanks and pipeline,we will prt:pare an environmental initial
study and proposed negative declaration following CEQA Guidelines. We will distribute
preliminary documents to the State Clearinghouse and responsible agencies. We will
coordinate a public hearing,receive oral and written comments and prepare responses, we
will prepare a final negative declaration and notice of determination and file appropriate
i final documents with the County Clerk and State Clearinghouse.
i
j Based on the location of the proposed project site, an archaeological site survey and record
search may he an npprnpriare.component to the environmental review. We will include
archaeological services as part of the environmental review.
�. Tank Design-We will provide design of the water storage tanks in accordance with the
AWWA D-100 standard for welded steel tanks. We will prepare contract drajvutgs and
technical specilluatiurls.
! i
3. Tank Site Engineering-We will prepare a grading plan,drainage caloulatioas, rctaiuing
wall design, and design of access road,paving,slope protection, and erosion control,
including contract plans and specifications. 3
