Landscape Master Plan and Projected Site Water Requirements After reviewing the existing landscape with the UNK staff, all existing and proposed landscaped areas were identified. All area figures within this report reflect all anticipated landscape improve- ments to the main campus. Based on the landscape areas identified by the Landscape Master Plan, the associated site water requirements have been established. The peak season application rate is based on a 30-year his- torical evaluation of the weather in the Kearney area. All water use projections and peak flow calculations are based on applying required ir- rigation water within a six-night, eight-hour per night weekly watering window. This allows for all irrigation to take place when activity at the cam- pus is low and the wind and temperature condi- tions are at optimum levels for the most efficient application of the irrigation water. The resulting areas and flow values are included in Table ‘A’ (Proposed) and Table ‘B’ (Existing). The build-out summary for the proposed campus is as follows;

The seasonal water use requirements are con- sidered for established plant material irrigation. Any new plant material will require 2-3 times the water for establishment. To meet these demands, the system will need to operate at approximately 70% efficiency. This will require implementing several steps, from in- stallation to operation, of a new irrigation system for the reasons covered in this document. The current combined campus capacity utilizing the building taps, dedicated taps and pumps is estimated at approximately 1780 gpm .
