AGENDA TITLE: Authorize City Manager to Enter Into a Contract with Brown & Caldwell to Update
City of Lodi's Urban Water Management Plan
MEETING DATE: September 20, 2000
PREPARED BY: Public Works Director
RECOMMENDED ACTION: That the City Council authorize the City Manager to execute a contract with
Brown & Caldwell to update Lodi's Urban Water Management Plan and
appropriate $25,000 for the project.
BACKGROUND INFORMATION: The California Urban Water Management Planning Act requires
that each urban water supplier providing water for municipal
purposes either, directly or indirectly, to more than 3,000
customers, or supplying more than 3,000 acre-feet of water
annually, prepare, update, and adopt its urban water management plan (UWMP) at least once every five
years. Lodi exceeds both these criteria and the next plan is due by December 31, 2000.
Lodi completed its original UWMP in 1991, a required addition in 1993, and the required update in 1995.
Attached is a checklist of the items required to be addressed in the UWMP. There are numerous new
provisions required in the 2000 update. City staff will provide much of the information for many areas of the
update.
Many of the new provisions can be completed more efficiently by a consultant familiar with UWMP's.
Brown & Caldwell is a firm with a good reputation that is completing UWMP's for numerous water suppliers
and has completed several other projects for the City of Lodi. Attached is Brown & Caldwell's proposal to
prepare Lodi's UWMP.
There is no direct penalty for not updating the UWMP. However, not updating the plan can adversely effect
Lodi's ability to procure certain loans and grants from the State.
FUNDING: The money for this project will come from the Water Utility. A portion ($10,000) is available in
the Water Operating Budget and the balance ($15,000) is from Water Fund balance.
Project Estimate: $ 25,000

Scope of Work Preparation of Urban Water
Management Plan
This scope of work consists of preparing an urban water management
plan (plan) for the City of Lodi (Ciq,). The objective for the urban
water management plan is to fulfill the requirements of the California
Urban Water Management Planning Act and the reporting requirements
of the California Urban Water Conservation Council.
The scope of work consists of several tasks that are in conformance
with the Urban Water Management Plan Checklists and %X"orksheets
provided by the California Department of Water Resources.
Task 1. Detailed Water Management Plan Outline
Before starting the detailed preparation of the urban water management
plan, a detailed outline will be prepared for review with City staff. The
goal is to reach a consensus regarding the detailed outline, structure, and
content of the plan.
Task 2. Data Collection and Review
Pertinent information needed to prepare the urban water management
plan will be collected and reviewed. A written data request will be
submitted to the City. The data and information will be reviewed to
become acquainted with the service area, existing sources of supply,
transmission and distribution facilities, existing system operations,
historical demands, potential sources of supply, and any other
information as required to prepare the urban water management plan.
Task 3. Description of Water System (Supplier
Service Area)
The characteristics of the water system including geographic location,
demographic information, customer description, climate, system
facilities, and sources of supply will be described. We will utilize the
information in the last master plans prepared for the City, and update
the information to reflect recent changes. The following subtasks
describe the work for this task.
Task 3.1 -Prepare Service Area Map
A map for inclusion in the plan depicting the service area and principal
features of the water system will be prepared.

Task 3.3 -Describe Existing and Future Land Use and Population
Existing and future population, dwelling units, and employment will be
quantified using available census data, state information, and other
information sources. The number of existing customers broken down
by customer category will be presented. The existing population and
land use xvill be used under Task 7 to develop the unit water demand
factors.
Task 4. Agency Coordination
Assistance will be provided to the City to coordinate preparation of the
plan with appropriate agencies, including other water suppliers, water
management agencies, and relevant public agencies.
Task 5. Water Use
Past and current water use will be quantified and projected in 5 -year
increments to 20 years, identifying the uses among water use sectors.
The following subtasks describe the work for this task.
Task 5.1 -Describe Existing Water Use Characteristics
Existing and historical water use will be defined in terms of annual,
monthly, and maximum day demand. Maximum day and peak hour
peaking factors will be determined. Unit water demands
(gallons/capita/day) for major user classes will be developed. The unit
water demands will be used to project future water use.
Task 5.2 -Develop Future Water Requirements
Future water requirements using the unit water demand factors and
future population and employment will be developed. Future water
requirements will be expressed for each year to 20 years and for buildout
conditions. Future water requirements will be presented in terms of
annual and maximum day use.
Task 6. Water Supplies
The existing and planned sources of water available to the City in 5 -year
increments to 20 years or as far as data are available will be identified
and quantified. 'These sources include local water supplies
(groundwater, surface water, recycled water, other), imported water
supplies (local and regional water wholesalers and interconnections with
neighboring systems), and potential water supplies from any other
source.
Task 6.1 -Transfer or Exchange Opportunities
Opportunities for exchanges or transfers of water on a short-term or
long-term basis for each water system will be described.
Task 6.2 -Inconsistent Water Source

The reliability and vulnerability of the water supply to seasonal or
climatic shortage will be described. The number of years the water
supply is expected to enter a Stage 1, or greater, water shortage over 20
years will be defined.
Task 6.5 -Water Supply Reliability Comparison
Water supply reliability data will be presented for an average water year,
a single dry water year, and multiple dry water years, based on historical
water supply data.
Task 7. Recycled Water Potential
The plan will include a description of the wastewater collection and
treatment systems in the service area and the potential for use of
recycled water-.
Task 7.1 -Wastewater Generation, Collection, and Treatment
The plan will provide quantification of the current and projected future
amounts of wastewater collected and treated in the service area.
Task 7.2 -Wastewater Disposal and Recycled Water Uses
Recycled water and its potential for use as a water source in the service
area will be addressed. The plan will describe methods of wastewater
disposal in the service area. The plan will also include a description of
the recycled water currently being used in the service area, including the
type, place, and quantity of use. Potential uses of recycled water will be
identified and quantified, including agricultural irrigation, landscape
irrigation, wildlife habitat enhancement, wetlands, industrial reuse,
groundwater recharge and other appropriate uses. The technical and
economic feasibility of serving those uses will be determined based on
information available from the local wastewater agency. The use of
recycled water within the service area will be projected for 5, 10, 15 and
20 years.
