AGENDA TITLE: Adopt Resolution Authorizing City Manager to Execute Task Order No. 34 with West
Yost Associates, of Walnut Creek ($58,700)
MEETING DATE: August 7, 2013
PREPARED BY: Public Works Director
RECOMMENDED ACTION: Adopt resolution authorizing City Manager to execute Task Order
No. 34 with West Yost Associates, of Walnut Creek, in the amount
of $58,700.
BACKGROUND INFORMATION: The City's White Slough Water Pollution Control Facility (WSWPCF)
typically discharges treated effluent to Dredger Cut during the
months of October to April each year. During the remainder of the
year, the treated effluent is utilized within the City's land application area for irrigation of fodder crops. To
maximize the use of treated effluent for irrigation, a study is needed to evaluate the current water use and
water balance of flows at the WSWPCF. Upon request by staff, West Yost Associates (WYA) furnished
the City with a proposal to provide engineering services to complete a Land Application Area Expansion
study at the WSWPCF. This study will evaluate potential alternatives for expanding the land application
area to maximize the use of treated effluent for irrigation at the WSWPCF.
The Task Order No. 34 scope of services, as detailed in the attached exhibit, includes the following
categories of work:
• Evaluate Effluent Flows
• Conceptualize Alternatives
• Develop Preliminary Facilities Layout and Sizing
• Evaluate Onsite Land Application Area Expansion
• Estimate Cost of Proposed Alternatives
• Prepare Technical Memorandum
• Provide Project Management
Staff recommends City Council authorize the City Manager to execute Task Order 34 with WYA in the
amount of $58,700.
FISCAL IMPACT: There is no expected fiscal impact on the City for this study.
FUNDING AVAILABLE: Wastewater Operating Fund (170403)

SUBJECT: Proposal to Provide Engineering Semces—Land Application Area
Expansion Study
Dear Larry:
West Yost Associates (West 'Yost) appreciates the opportunity to present to you this letter
proposal for engineering services related to the City of Lodi (Lodi) Water Pollution Control
Facility (WPCF) Land Application Area Expansion Study. The purpose of this study is to
evaluate potential alternatives for expanding the land application area to max mize the use of
treated effluent for irrigation. The potential alternatives that will be evaluated wider this study
were developed based on discussions with the City, and are as follows;
• Expansion of the treated water storage volume so that the storage "balances" with the
Ci"wned areas that are currently irrigated with treated wastewater. The goal of this
alternative would he to meet the existing irrigation demands without supplemental
water supplies during; most years.
• Expansion of the treated water storage volume so that the storage "balances" with the
all of the existing City -owned irrigated properties (mcluding the 90 -acre area currently
irrigated with well water). The goal of this alternative would be to maximize the use to
treated effluent for irrigation on the existing City -owned land.
• Expansion of the treated water storage volume and City -owned irrigated properties so
that use of available treated effluent for irrigation is maximized at the 60 mgd average
dry weather flow condition.
• Expansion of the treated water storage volume and City -owned irrigated properties: so
that use of available treated effluent for irrigation is maximized at the 7.0 mgd average
dry weather flow condition.
• Expansion of the treated water storage volume and City -owned irrigated properties so
that use of available treated effluent is for irrigation is maximized at the 8.5 mgd
average dry weather flow condition.

SCOPE OF SERVICES
Task 1. Evaluate Effluent Flows
West Yost will develop an estimate of the monthly effluent flow factors for the WPCF based on
the following information:
• Recent influent and effluent flow data
• Anticipated water demands from NCPA power generation facilities
• Historic demands from the San Joaquin County Mosquito and Vector Control District
These monthly flow factors would be applied to an influent flow condition to predict effluent
flows. This information will be used to support the water balance modeling effort described in
Task 2.
Task 2. Conceptualize Alternatives
Vilest Yost will ftuther define each of the alternatives presented above. This work will include the
development of conceptual water balances to identify the required irrigation and storage areas.
The results of the efforts completed under Tasks 1 and 2 will be presented to the City for
comment and feedback prior to initiating the tasks described below.
Task 3. Preliminary Facilities Layout and Sizing
Based on the work developed under Task 2, West Yost will develop preliminary layout and sizing
for the irrigation areas needed under each alternative. West Yost will develop conceptual
snapping of each of the alternatives, showing the potential irrigation expansion areas adjacent to
the WPCF properties (based on proximity to existing facilities and existing parcel designations),
and a preliminary irrigation water transmission alignment. These preliminary layouts will serves
as the basis for the cost estimates provided under Task 5.
Task 4. Onsite Land Application Area Expansion
The City's existing land application area includes 90 acres that are currently irrigated with well
water. West Yost will identify the specific facilities needed to expand the existing treated effluent
irrigation system to cover this area. Work will include:
• Review existing irrigation pump station condition and capacity, and evaluate existing
irrigation system hydraulics to verify the feasibility of supplying the site front the
existing pumping facilities.
• Determine pump station improvements needed to supply the expansion site if the
existing pumping facilities are not adequate.
• Evaluate option of constructing a booster pumping station near the expansion site.

a Prepare figures and preliminary cost estimates for both approaches.
a Meet with the City to review the findings and select a preferred approach.
Task 5. Estimated Costs for Proposed Alternatives
West Yost will develop a planning level cost analysis for each alternative. These estimates will
include the cost estimate descn- bed in Task 4 for expanding the existing land application area.
Task 6. Technical Memorandum
The information developed under Tasks 1 through 5 will be presented in a Technical
Memorandum UK. Upon review by staff, West Yost will participate in a meeting with City staff
to review the findings. A final TM will be prepared incorporating City comments.
Task 7. Project Management
West Yost will provide management and coordination activities related to this study. Work
performed will be summarized on monthly invoices, and all work will be reviewed by principal
'Nest Yeast personnel.
PROJECT BUDGET
The total fee for the scope of work described above is estimated to be $58,700. A breakdown
of the estimate is shown in the table below. West Yost will perform the work on a time and
materials basis at standard company charge rates, and will not exceed the estimated cost without
written authorization. If additional budget is required to complete work identified herein, we Will
notify the City before exceeding the authorized budget amount.
