REGIONAL WATER SUPPLY PLAN 27 CITY OF FORT WALTON BEACH  Also in FY 2007- 08, the City is begimring a water meter change out program. The initial year includes the replacement of all commercial water meters 2-inch and larger, which includes over 100 meters. The remaining four years of the CIP program consists of replacing all 9,800 residential water meters. The City last replaced all of its water meters in 1996. SECTION 5 - HISTORICAL DATA AND PROJECtIONS There is probably no more important parameter for planning purposes than the development of future population projections. Since residential water consumption accounts for a majority of the aquifer withdrawal, future population projections will be the basis for estimates of future potable water demands. Numerous methods of projecting populations exist. They include census data, the University of Florida Bureau of Economic and Business Research (BEBR), and historical consumption data related to the number of metered accounts. In order to standardize the method for projecting future populations throughout the City, the Utilities Department utilizes the BEBR projections in conjunction with the City' s Community Development Services ( CDS) Department, which utilizes the BEBR projections in all of its planning tools, such as the Comprehensive Plan. 5. 1 HISTORICAL POPULATION DATA In order to determine the current and future service population, the estimates for the three service areas must be combined. BEBR population data exists for the City of Fort Walton Beach and the Town of Cinco Bayou. However, there is no recorded data for the Eglin Heights Subdivision, so a " rule of thumb" factor of 2. 5 persons per residential meter has been used to determine the service population in that service area. Between 2000 and 2007, the City of Fort Walton Beach experienced a growth of 5. 2 percent, or 0.70 percent annually. The Town of Cinco Bayou' s population experienced an overall growth of 3. 7 percent, or 0.53 percent annually, over the same time period. For the Eglin Heights Subdivision, the population has fluctuated during this time period due to the change in active water meters each year. This service area has averaged 305 persons over the 2000 to 2007 period. Based on known population data from the City of Fort Walton Beach, interpolated data from the Town of Cinco Bayou, and water meter data from the Eglin Heights Subdivision, the 2007 estimated water service population is 21, 699 persons.

Based on the 150 gpcd consumption and the Individual Water Use Pennit limits, the City is capable of providing potable water service to all three service areas beyond the ten-year planning window. The population projections included in Table VI do not account for any population density increases that are proposed by the City' s CDS Department in the latest Comprehensive Plan update. The proposed density increases would allow for a minimum of 3,000 additional persons in the City limits. However, the time& ame of realization for the population increases is unknown and therefore, was not accounted for in this document. REGIONAL WA1ER SUPPLY PLAN 29 CITY OF FORT WALTON BEACH 5. 3 HISTORICAL POTABLE WATER PRODUCTION Thanks to conservation efforts from 2000 to 2007, the annual water production has declined 192.68 million gallons a year, or 10.25 percent. In this same period the service population grew by 5. 2 percent. As demonstrated earlier, the water production facilities are capable of producing far more than the current or foreseeable demands. The challenge is to stay within the withdrawal limits set by the Individual Water Use Penmt issued by the Northwest Florida Water Management District. Table VII compares the actual historical water production and the permitted water production from
