  Text Box: Notes: 1. The annual budget period corresponds to the Water Year, which begins on October 1 and ends on September 30 of the following Calendar Year. 2. Total monthly production for "Customer Service" in CAW's Laguna Seca Subarea systems was calculated by multiplying total annual proposed production (271 AF) times the average percentage of annual production for October, Novembert, and December (9.79%, 6.60%, and 5.42%, respectively). The annual proposed production total was based on the assumption that production from the Laguna Seca Subarea of the Seaside Groundwater Basin would not exceed 271 AF. The average production percentages were based on monthly data for customer service from WY 2000 to 2007. The 271 AF annual production limit is specified in the Seaside Basin Adjudication Decision and is subject to change. 3. It should be noted that, based on recent historical use, actual monthly use will likely exceed the proposed monthly production target. For example, in the October through December 2008 period, CAW produced 51, 38, and 30 AF, respectively, to meet customer demand in its Laguna Seca Subarea systems. In this context, the production targets represent the maximum monthly production that should occur so that CAW remains within its Standard Production Allocation for the Laguna Seca Subarea specified in the Seaside Decision. However, because the Seaside Decision allows CAW to combine its production in the Coastal Subareas with its production in the Laguna Seca Subarea in determining compliance, CAW can use production savings in the Coastal Subareas to offset overproduction in the Laguna Seca Subarea. 4. "Other" production sources refer to supplies transferred to Laguna Seca Subarea customers from CAW's Carmel River sources or water rights acquired from other producers in the Seaside Basin to produce additional water. For example, under emergency conditions, water can be transferred from sources that serve customers in CAW's main system, via an existing interconnection, to customers in CAW's Ryan Ranch system.
