A more dctailed discussion is included in the Appendices. 9.1 City and County of Broomfield The City and County of B.roomfield is located north of Denver and borders the intersection of Adams, Boulder, Jefferson, and Weld counties. Until the 1950s, only 1,00 people lived in the area. By 2004, Broomfield's population exceeded 46,000. Tn November 2001, Broomfield citizens voted to establish the City and County of Broomfi,eJd. Water Supply. Broomfield relies primarily on C-BT Project water and Denver Water for its potable water supply. The City owns 56 units of Windy Gap water, which i,s used when available or through the C.BT in-lieu program. Broomfield non-potable water supply includes flows from Clear Creek, Coal Creek, Walnut Creek, and Big Dry Creek and reuse of Windy Gap effluent when available. Broomfield also owns ditch and rese1\loir shares that arc used outside the City and County boundaries for non-potable uses including drought-tolerant sod produ.ction and biosolid disposal in Weld County. Broomfield recently compl.eted a water reuse system that allows the captnre of Windy Gap effluent to assist in meeting non-potable imgation needs. Although the current finn yield of this reuse water is zero, it is projected to provide 3,100 AF ofreuse water if the WGFP is implemented. Broomfield's cun:ent firm. water supply is 13,739 AF. Growth and Population Trend. Broomfield experienced steady growth in population and employment from 1980 through 1990, but the pace of that growth accelerated from 1990 through the year 2004. Population almost doubled from 24,640 in 1990 to 46,400 in 2004--;ln average annual. growth rate of almost 5 percent. Employment rose three-fold from 1990 to the year 2004, experiencing an average annual growth rate of9 percent. Broomfield's employment growth has bene.fited from its location along a major highway between Denver and Boulder. Current Water Demand. The City and County of Broomfield Water Department service area includes the e.ntire County, plus the Jefferson County Airport and the Mile High Water District. Total potabl,e water use for the City and County of Broomfield peaked at about 3,290 MG or 10,100 AF in 2002, dropping in 2003 due to drought and related water use restrictions. Potable residential water deliveries nearly doubled between 1992 and 2003. Residential water use comprises an average of about 70 percent of total. use. Commercial water use represents approximately on.e- fourth of total Broomfie Id water use; these water demands bave been growing at a slightly slower pace than residential water use. Total water use per capita per day has varied within. a fairly narrow range during the 19905, averaging 188 gped. Residential gpcd have averaged 132 gpcd from 1992 through the year 2003. Projected Water Demand. Broomfi.eld's population is projected to peak at 83,300 residents in the year 2025 based OIl a 2.9 percent annual increase from 2004 through buildout. This indicates an 80 percent increase in. population in 20 years. Employment in Broomfield is expected to grow faster than population, doubling by 2025 and continuing to grow beyond that. Total firm water requirements are projected to incrcase from 14,300 36 PAGE 03/10
