Executive Summary

Profile of Proposed Facilities

The District currently relies on 10 wells that pump groundwater from the Denver
Basin. As previously mentioned, groundwater levels are declining throughout the
South Metro area and will eventually increase pumping costs and require the District
to add new wells if the District remains on groundwater. The District is currently
evaluating renewable surface water supplies through the development of an
Integrated Water Resources Plan (IWRP). The IWRP will provide an action plan and
decision framework for the District to acquire renewable supplies. However,
currently it is not possible to conclusively describe the District's long-term water
supply plans and identify future facilities. Regardless of whether the District chooses
to incorporate surface water supplies or solely remain on a groundwater supply, the
cost of water production will increase in the future.

Conservation Goals

The profiles of the District's water supply and demands summarized above were used
to develop the following water conservation goals:

1. Provide a water savings target of an additional 175 to 220 AFY based on 2003
water demand patterns (16 to 20 gallons per capita day (gpcd) based on
projected population at buildout) through existing and additional conservation
measures and programs.

2. Select conservation measures and programs that target outdoor irrigation and
customers of high use. Target customers include the following:
. Residential (indoor and outdoor usage)
. District irrigation of parks and open space
. HOA irrigation

3. Closely monitor District irrigation on parks and open space.
. Maintain 2005 irrigation levels on parks and drip irrigation
. Reduce open space irrigation by an additional 10 percent (5.9 AF) with a total
outdoor District usage not to exceed 93 AFY. (District metered usage in 2005
was 98.9 AF)

4. Provide assistance to the homeowner associations in reducing irrigated turf by
25 percent.

5. Select conservation measures and programs that are compatible with the
community.

6. Establish a monitoring system that collects a sufficient amount of data to
effectively measure the success of conservation programs and measures on an
annual basis.

Evaluation of Conservation Measures and Prograllls

A set of preliminary conservation measures and programs were selected for further
evaluation. This set consisted of existing conservation measures/programs as well as
measures/programs that were likely to contribute to meeting the conservation goals,
are compatible with the community, and provided water savings. Estimated water
