EXECUTIVE SUMMARY <br />A. PURPOSE <br />The purpose for this study is to update the City's Comprehensive Water Plan based on <br />current population and land use projections. These projections are provided by the City's <br />2030 Comprehensive Plan. The planning period is 2012 through 2031. Water use <br />estimates were developed utilizing population and development projections provided by <br />the City. Infrastructure improvement plans for water supply, treatment, distribution and <br />storage were developed to meet the projected water use of the City. <br />B. WATER USE PROJECTIONS <br />Water use projections form the basis of planning for future water infrastructure needs. <br />Water demand projections are based on forecasts of residential, commercial and <br />industrial water demands. Projections are first developed for population growth in <br />commercial and industrial development. Historical water use data is evaluated for <br />average day and maximum day water use. Future water use projections are then <br />developed based on growth forecasts and water use trends. <br />Key concepts utilized in developing service area population projections are as follows: <br />1. The 2011 population being served by the water system is estimated to be 11,434 <br />people. <br />2. Water service will be provided to an additional 260 customers per year from 2012 <br />through 2031, within the comprehensive planning area. <br />3. Water service will be provided to an additional 63 customers per year, from 2013- <br />2021 (567 total units) in the development included in the special area plan. <br />4. From 2012 through 2019, the population per household is projected to be 2.87. <br />5. From 2020 through 2031, the population per household is projected to be 2.70. <br />6. High density residential development is equivalent to 0.7 equivalent residential <br />units (ERUs). <br />Water use projections are typically made on a per capita basis for systems without a <br />significant large water using industry.
