estimated to be a minimum 60,000 acre feet per year. The County's
interest of 81% is equal to a minimum project safe water yield of 48,600
acre feet per year.

From Table! 11-1, the current use of ground water in Arapahoe County
(11,594 acre feet per year) is approximately 24% of the present county's
interest in Union park of 48,600 acre feet per year. The projected year
2010 ground water use (29,719 acre feet per year) is approximately 61% of
the present county's interest of 48,600 acre feet per year. These
figures clearly show that the county needs renewable water supply to
re1uce dependency on non-renewable groundwater sources.

C. Arapahoe County Comprehensive Plan

I n October, 1985 Arapahoe County compl eted the County Comprehensi ve Pl an.

In the Comprehensive Plan a land use map was developed that served as the

basis for developing water demands. the planning horizon utilized

covered a periOd over the next 30 years. Future water demands were based

on the population growth and developinent within the unincorporated areas

of the County.

D. Estimated Design Parameters and Assumptions

The following parameters were utilized by the county Planning Department,

working closely with their sub-consultants in the areas of population

projections and water resources engineering to deter:nine total water

supply requirements.
