renewable aquifer and it cUlTently supplies water to much of the south metro area and northern El
Paso County. CPN supplies water and wastewater services to approximately 3,000 homes and
25 commercial users and although they can currently meet their water supply needs, they
anticipate a continued decline of groundwater levels due to growing population and increase in
demand.

CPN has patiicipated in multiple regional water planning studies and developed an Integrated
Water Resources Plan (IWRP) in 2006, which evaluated the District's demands, conservation
measures, and the short-tem and long-tenn sustainability of existing groundwater supply.
Conservation was identified as a significant component of CPN's future water management
strategy. In the beginning of 2006, CPN submitted a grant application to the OWCDP and on
March 23,2006, CPN was awarded $20,000 from the Water Conservation Planning Grant
Program for development of a Water Conservation Plan. The Plan was approved by the CWCB
in the summer of 2006, at which time the entity became eligible for water efficiency grant money
to assist with implementing their plan.

One of the goals set f01ih in CPN's Water Conservation Plan is to closely monitor CPN's
irrigation on parks and open space. In efforts to meet this goal and their targeted water savings
goal of 175 to 220 AFY by 2014, CPN proposes to install a CALSENSE irrigation management
system. This system provides technical features which allow greater central control and
improved irrigation efficiencies. CALSENSE products have been utilized throughout the
United States and CPN will be the first District in Colorado to benefit from the water
management system. The applicant plans to provide detailed metered data of irrigation
application rates; a fact sheet with general information on the installation, operation and overall
water saving benefits of the System; and on-site demonstrations for water providers, parks and
open space managers, and irrigation specialists, to be benefited by all interested patiies. In
Colorado, outdoor irrigation comprises of over 50% of utilities water supply demand, therefore
this project could provide valuable information and education other Colorado municipal water
providers.

The applicant has demonstrated their financial ability to provide 40% of the project budget with
matching funds in the form of $22,977 in-kind contribution and $14,239 monetary contribution.
The OWCDP has evaluated the grant application and finds that it meets the CWCB Guidelines
for the Water Efficiency Grant Program.

Recommendation:

The OWCDP recommends that the Board award a Water Efficiency Grant in the amount of
$56,191 to Castle Pines N01ih Metropolitan District to aid in achieving goal # 1 and #3 identified
in their Water Conservation Plan through implementation of the CALSENSE Irrigation
Management System.
