This USU research and Extension report contains an analysis of landscape water use for the Utah State Capitol grounds. It is being provided in response to a legislative request for this information. The Capitol grounds crew requested and received a Water Check in July and August of 2018. It was provided through the Water Check program affiliated with the Center for Water Efficient Landscaping (CWEL) at Utah State University (USU) Extension. The Water Check program has been offered under contract with Metropolitan Water District of Salt Lake & Sandy since 2009 and delivered to customers in the Salt Lake City Department of Public Utilities (SLCDPU) service area as part of Utah’s “Slow the Flow” initiative. The Utah State Capitol’s Water Check report is contained in the Appendix. More recently, the WaterMAPS (Water Management Analysis and Planning Software) team, also part of CWEL at USU Extension, was asked to provide an estimate of the “capacity to conserve” water applied to landscapes at the Capitol. The WaterMAPS program currently has a collaborative USU Extension Water Initiative project with SLCDPU to analyze landscape water use for residential locations within its service area. The WaterMAPS team worked with SLCDPU in preparing this requested Utah State Capitol landscape water use analysis, relying on information and meter data that they prepared and provided. In this report, we focus on presenting the methodology and results of the WaterMAPS analysis for the Utah State Capitol grounds. The analysis looks at landscape water use from 2010‐2018 in order to identify recent patterns and potential opportunities for efficiency and conservation savings.
