A second run ofthe model involved utilizing all Water available for storage under the water rights,
and concluded Morrison could support 1,475 ~QR if Cooley Reservoir is expanded to provide
Morrison with 600 acre-feet or more of storage. Expansion of storage at the Cooley site is
expected with further mining at the quarry site, and the Agreement identifies this future additional
storage as Reservoir Site II. This second reservoir site will have a capacity of 2,000 to 3,000
acre-feet according the Agreement (Paragraph 4.1). Since essentially "unlimited" storage is
expected to be available at the Cooley site, thi~ Master Plan bases the ultimate development of
Morrison at 1.475 EQR.

A third trial run was performed with the m()del with the implementation of lawn watering
restrictions during critical dry periods. With a 15% reduction in outdoor wateril1g, Morrison could
likely sustain an additional 135 EQR with unlimited storage. However, Morrison should maintain
some margin of safety, and it is recommended to limit the ultimate growth to a level sustainable
without conservation measures factored into the analysis.

If the Red Rock:s Center area develops, and bElcomes a Morrison water customer, the capability
of the Morrison water system could be increaliled to serve additional taps through:

. Acquiring some water rights owned by the Mt. Carbon District.
. Requiring the area to construct a dual irrigation water system which would use treated
wastewater from the nearby Morrison WWTP as a source. It is noted that this would
require Morrison to return to water COlJrt.

Note also that the Cooley annexation agreemElnt recognizes the possibility that additional water
rights can be furnished to Morrison for devEllopment of the Cooley parcels. The additional
amounts of water available cannot be accurately quantified at this time. However, the potential
indicates the desirability of conservatively sizing proposed facilities.

Development Priority
Given an ultimate level of development of 1,475 EQR, or an equivalent population of 4,425
people, (commercial development is included in the EQR figure so the actual number of
permanent residents at full build-out will be less), Morrison must prioritize the areas where water
will be made available for growth. Based on a Town Board/staff work session consensus, the
following is a summary of prioritized development proposed for Morrison:

1. Complete development within the present Town boundaries.
2. Develop Red Rocks Center as commercial development east of the Hogback.
