Memorandum
To: Board of Directors
From: Neil Kaufman, Water Systems Engineer
Date: May 30, 2002
Subject: PROPOSAL TO PERFORM PRELIMINARY DESIGN WORK FOR TWO
STORAGE TANK SITES AT DONNER LAKE
BACKGROUND:
As part of the ongoing reconstruction of the Donner Lake Water System, there is a need to
construct at least two storage tanks on the north shore of the lake, and possibly a third on
the south shore. One storage tank would be equal in elevation to the existing Wolfe Estates
Tank and would replace the existing Greenpoint Springs Tanks. The other would be equal
in elevation to the District's existing Armstrong Tank and would replace the existing Upper
Tanks located north of Interstate 80. The third potential tank is the replacement of the
existing Southside Tank off Mount Judah Drive.
1 have identified potential sites for both of the tanks on the north shore of the lake. A
preliminary review of environmental, cultural and geotechnical issues has been performed.
Contact has also been made with the property owners. To date, both sites appear to be
feasible.
At this time, I would like to proceed with developing a preliminary design for both sites. This
preliminary design will accomplish three main goals:
• Define the exact amount of land needed at each site to allow acquisition of the
property.
• One site has a potentially sensitive area. The preliminary design will determine
whether or not this sensitive area would be impacted by the construction of the tank.
• One potential site is located on land owned by the Town of Truckee. The town has
asked that the District hold an open meeting with residents to discuss the District's
plans for the tank. From the preliminary design exhibits would be developed to be
used at such a public meeting.
RECOMMENDATION:
Accept the proposal from Sauers Engineering to develop preliminary designs for two storage
tank sites at Donner Lake in the amount of$16,500.

SUBJECT: DONNER LAKE STORAGE TANKS - PROPOSAL FOR PRELIMINARY
ENGINEERING SERVICES
Dear Neil:
This letter is our proposal for professional services for the preliminary design of two
proposed water storage tanks. The two tanks are being considered as part of the ongoing
reconstruction of the Donner Lake water system. The preliminary design will provide
information on the areas affected by construction of the tanks, access roads, and
appurtenant facilities. This will allow the District to determine the amount of property
needed for the projects and identify any areas which may be impacted by the construction
Scope of Services
We propose to provide the following services:
1. Grading Plans -Using mapping, topography, and geotechnical information
provided by the District,we will prepare grading plans for each of the two tank
sites. We will determine the extent of cuts and fills, and determine the locations of
drainage facilities.
2. Access Road Layout -We will provide layouts for access roads for each of the
tanks. The layouts will include road alignment and grade, and the extent of cut and
fill required for construction.
3. Underground Facilities - We will identify likely locations for underground
facilities to the tank sites including water pipelines, overflow/drainage pipelines,
power conduit, and communication conduit in order to determine whether
additional easements may be needed for the projects.
4. Preliminary Design Plans - Based on the above tasks, we will prepare preliminary
design plans for the tank sites and access roads. These preliminary plans will be
suitable for use as exhibits depicting the tank construction projects.

Schedule of Services
We anticipate the preliminary design tasks described above will completed
approximately thirty days following authorization to proceed and receipt of District
furnished information.
Engineer's Fee
We propose to provide the services described above for a fixed fee of$16,500.00.
Closure
Thank you for the opportunity to provide this proposal for professional services for this
project. I am available to discuss this proposal with you at your convenience and with
the Board of Directors at the June 5, 2002 board meeting.
Yo truly,
