Filings for a Sustainable System
1. Conservation December 14, 2007

For rates in 2009 – 2011
3. Rate of Return May 2008

Also: 1) Ralph Lane – 29 customer system located in Salinas
2) Chualar – 189 customer system located in So. Mo. Co.

Satellite Systems by the Numbers
• Total of seven separate water systems• 15 wells with various treatment measures• 27 storage tanks• Multiple pressure zones• 2,000 total customers • 1,153 AF of water used per year• 0.5 AFY per customer usage vs. 0.17 AF per customer on main
system - 3 times higher• Satellite peak day demands = 300% higher than average day
demand• Main system = 60% higher than average day demand• Supported and operated by employees of the Monterey main
system

Water Supply Sources• Ryan Ranch, Hidden Hills, Bishop
Seaside Basin (Laguna Seca Subsystem) Zero water allotment from adjudication Allocations and tiered rates proposed
• Ambler Park & Toro El Toro Groundwater Basin Hydrologically contiguous to the Seaside Basin Overdraft (removing more water than is being replenished each year) Allocations and tiered rates proposed in Ambler Park, not Toro
• Ralph Lane & Chualar Salinas Basin groundwater Currently no water restrictions on use No allocations proposed; No tiered rates proposed for Chualar
7
Seaside Basin Adjudication Changed SupplyFor Ryan Ranch, Hidden Hills & Bishop
• Decision issued March 2006
• 2,500 AF total reduction from recent pumping levels required by 2021
• Zero AF allocation for Satellite Systems (Currently Use = 761 AF)
• Seaside Basin Satellite Systems will use the Seaside Basin customers
(non-satellite) allotment for their water supply
• Seaside Basin Satellite System rates will be the same as main system
rates (except Coastal Water Project and San Clemente Dam
surcharges)
• Interconnects system with main system to alleviate Laguna Seca
situation

Ambler Park & Toro
• Water supply is from the El Toro basin
• Hydraulically connected to the Laguna Seca subarea of the Seaside Basin
• California American Water has 800 customers in the two systems
• Declining water levels while pumping is increasing
• El Toro Basin also have the following: Hundreds of individual well users
2 commercial well systems
150 community water systems (mutuals)
• Geographic area of El Toro Basin greater than the Seaside Basin area
• Monterey County Water Resources Agency (MCWRA) conducted hydrologic study of Basin in 2007
10
El Toro Basin Hydrologic Study
• Conducted by Geosyntec for MCWRA
• Study completed in July 2007
• Major source of groundwater replenishment is precipitation
• Groundwater overdraft conditions exist
• Water supply being maintained by reducing groundwater storage
• Hydraulically contiguous with the Laguna Seca area of the Seaside Basin
• Recommends a collaborative groundwater management program with Laguna Seca sub-area producers
• Need to asses potential risk of ground subsidence near Highway 68 due to continued decline of groundwater levels
• Need to evaluate alternatives to enhance water supply and promote conservation measures
11
California American Water Ambler Park & Toro Recommendations
• No water supply quantity enhancements proposed in this filing
• Continue to supply customers with water from the El Toro Basin through 2011
• Currently systems are not interconnected• Toro interconnected to Hidden Hills• Rates less than main system customers• Allocations and tiered rates proposed in Ambler Park• No allocations or tiered rates proposed in Toro
12
Chualar & Ralph Lane
• Water supply from Salinas Groundwater Basin• No current restrictions or fees imposed on use of
groundwater basin water• Cost to produce water through 2011 anticipated to be
inexpensive• Proposed rates are considerably less than other satellite
systems and main system No tiered rate structure proposed in Chualar No allocations proposed No mandatory conservation required
• No interconnection to other systems currently or proposed

Summary of major items
• Total Overall Revenue Increase requested = 120%
• Satellite systems and main system customers could be more,
depending on use and water allocations
• Satellite systems of Chualar and Ralph Lane – lower rates due to
water supply situation
• Allocations and conservation rates (5 tier structure) implemented for
all except Chualar, Ralph Lane and Toro
• Satellite Systems are high users of water, complicated systems, high
amount of facilities, lack a long-term water supply (except Ralph
Lane and Chualar)
• Customers on tiered rates could experience a 1,000% increase in bill
if most of their water use is in the 5th tier.
17
Conservation application filing
• Further conservation needed due to reduced water supply
• $1.7M additional annual expenses for conservation items
• 5% rate increase for conservation expenses
in addition to GRC
• Rates will impact large users more than average users
• Accelerated timeline; interim phased decision
• Rebates for water saving devices available and encouraged
• Allocations established for all customers except Ralph Lane
and Chualar due to water supply situation
