F. WATER UTILITY FUND EVALUATION <br />The water utility fund was evaluated using the following parameters: <br />■ 260 new customers will be added to the system every year during the planning <br />period from the Comprehensive Plan development areas <br />■ 567 new customers will be added from the special area between 2013 to 2021. <br />■ Implementation of the Surface Water Treatment Facility phased construction <br />approach as outlined in Chapter 4. <br />■ Capital water supply and treatment projects will be financed at a 4% interest <br />rate over a 20-year term. <br />■ Phase I Water Treatment Facility will be 20% grant funded. Assumption <br />based on regional positive impact for implementing surface water supply and <br />treatment facility. <br />■ Distribution system improvements will be implemented as outlined in Chapter <br />5. <br />■ Distribution system improvements will be funded through Utility Fund <br />reserves. <br />Based on the parameters outlined, the impact on water rates and charges of the Water <br />Utility Fund are summarized as follows: <br />■ Water rates projected to increase 2.0% annually <br />- 2012 rate is $2.38/1000 gallons for the first 15,000 gal/qtr <br />- 2.0% increase in water rates to begin in 2014 <br />■ Water Availability Charge (WAC) decreases by 30% in 2013 from $1,640 per <br />connection to $1,148 in 2013 <br />■ Trunk charge decreases by 30% in 2013 from $2,226 per connection in 2012 <br />to $1,558 in 2013 <br />■ WAC and trunk charge to increase 2.5% annually beginning in 2014 <br />■ Beginning fund balance in 2012 = $8,346,319 <br />■ Fund balance decreases from $16,277,203 in 2018 to $4,305,861 in 2031 as <br />payments are made towards capital improvements <br />■ Projected revenue from new customers will generate 41.6% of total revenue <br />over the planning period <br />City of Ramsey, Minnesota — RI3.104504 Page 7 <br />Comprehensive Water System Study Prepared by Bolton & Menk, Inc. <br />
