<br />Appendix 2 ~ Castle Pines North Metropolitan District <br />(Castle Pines North) <br /> <br />Distn-ict Boundary/ Service Area <br /> <br />Castle Pines North serves an area of primarily single family residential and light commercial <br />development immediately north of Castle Pines and west of 1-25 in the central part of the Study <br />Area. The district's water supply is developed exclusively from non-tributary wells with <br />adjudicated rights in the Upper and Lower Dawson, Denver, Arapahoe and Laramie-Fox Hills <br />formations. All water uses in Castle Pines North are currently met by pumping five Arapahoe <br />wells, one Denver well and one Lower Dawson well that was completed in 2000 for irrigation <br />purposes. Potable water is treated (iron and manganese removal) and disinfected before delivery <br />to customers. The District also operates an augmentation plan to reclaim return flows from Happy <br />Canyon Creek and other local drainageways. Castle Pines North also has the right to reuse treated <br />wastewater effluent from the Plum Creek Wastewater Authority (see Appendix L) - that non- <br />potable water system will be used in the future to irrigate open space areas and the Ridge golf <br />course. <br /> <br />The service area includes 2,100 acres of which 980 acres are currently developed. <br /> <br />Current and Projected Water Usage <br /> <br />In 1996, Castle Pines North used 550 acre-feet of water. By 2000, the annual water demand had <br />increased to 1345 acre-feet and reflects the significant growth in demands that have been met by <br />expanding the pumping of the Denver Basin aquifers. Extensive residential and some commercial <br />development has occurred in the last 5 years and the District currently serves approximately 2200 <br />SFEs. It is expected that build-out of the District will occur by year 20 10 with a total of 3400 <br />SFEs. An estimated 2,176 acre-feet per year of additional water is required to meet build out <br />conditions. If adjacent areas elect to be served by Castle Pines North, they would be required to <br />dedicate adequate water supplies to meet the projected water demands of the zoned urban <br />densities. <br /> <br />Table B-1 - Historic and Projected Water Uses - Castle Pines North <br /> <br />Year <br /> <br />SFE <br />Connections <br /> <br />1993 <br />1994 <br />1995 <br />1996 <br />1997 <br />1998 <br />1999 <br />2000 <br />Ultimate <br />(year) 2010) <br /> <br />2200 <br />3400 <br /> <br />Annual Water Delivered <br />(Ac-ft) <br />407 <br />461 <br />430 <br />639 <br />776 <br />954 <br />1035 <br />1345 <br />2176 <br />
