The City's current Capital Improvement Plan was used to determine expenditures for the years 2017 to 2020. For the years 2021 to 2040, the above costs were spread evenly over the 20 year period, while being inflated at a rate of 3% per year. D. DEVELOPMENTAL IMPACT ON COMPREHENSIVE WATER PLAN Population and Growth Actual and projected development within the City of Ramsey since the 2012 Comprehensive Water Plan was developed are summarized as follows: • Connections from 2012-2015 are as follows: - 2012: 295 - 2013: 164 - 2014: 66 - 2015: 258 - Avg: 196 • Projected development is as follows: - 160 Residential Units/Year, (50% High Density) - 10 Commercial/Industrial Acres/Year - 567 Residential Units in NE Expansion Area The development projections above are projected to occur from 2016 to 2040. The total projected number of new units to be served by the water system, after a high density unit adjustment of 0.7 per high density unit, is 3831 units. This represents an average of 160 units per year will be developed. The attached Table 1 provides a summary of both the 2012 comprehensive Water Plan population and water demand projected, and the updated projections based on new development information. E. ANALYSIS Our detailed analysis (depicted on a spreadsheet at the back of this report) provides an evaluation of the impact of development and proposed improvements on the current rate structure. The following assumptions were made for the analysis: • Capital expenditures for 2017 to 2020 were taken from the City's current Capital Improvement Plan. • Capital expenditures for the years 2021 to 2040 were based on assumptions described in Sections B and C above. • Operating expenses of $836,662 were used for 2017 and then inflated at a rate of 4% per year for the duration of the analysis period. • Treatment facility operating expenses were assumed to begin in 2029 at an annual rate of $1,000,000 per year and then inflated at 3% per year each year after 2029. • Water usage rates of $2.57/1,000 gallons for 2017 were used and then inflated at a rate of 2% per year after 2017. • Water Availability Charges of $1,236 were used for 2017 and then inflated at a rate of 2.5% per year after 2017. • Trunk charges of $1,720 were used for 2017 and then inflated at a rate of 2.5% per year after 2017.
