19 W-IT1S2: Replace or retrofit City building plumbing fixtures to meet or exceed current code requirements. Over the past few years, the Public Works Department has worked hard to replace or retrofit City plumbing fixtures. For example, aerator devices have been installed on City building faucets to reduce water usage and most (if not all) toilets already are 1.6 gallons. Recently, several urinals at the library were replaced for 1/8 gallon flushes. It should be noted that there are still replacements to be made, but this is ongoing, as is appropriate, needed, and within budget. According to the Facilities Manager, an audit would be required and could be reasonably accomplished to determine a more thorough replacement schedule. • Perform an audit on City building plumbing fixtures and determine what replacements may be made to meet or exceed current code. 20 W-IT1S3: Achieve 80% of all the new construction water efficiency points in the USGBC LEED for water use reduction and rain water management, applicable to specific type of building. The new Recreation Center is being designed to earn between 60-79 points (gold standard) under the Water Use Reduction & Rain Water Management section of the USGBC LEED rating system. Due to cost, however, the City will not seek formal certification. The efficiency measures are expected to yield significant water usage savings over the life of the building, which would affect water production costs by the City. See CE-IT2S4 about potentially creating a City policy to address environmental standards for new City building construction. • No recommended action. See CE- IT2S4. 21 W-IT1S4: Manage and upgrade infrastructure to reduce leaks in the system. The Public Works Department habitually checks for leaks in the metering system, performing an audit annually on a different third of the system. This year, they will be performing a regularly scheduled complete audit. Known leaks are addressed within 24 hours. Leaks are costly and usually noticeable, often causing larger infrastructure problems (i.e. sinkholes in pavement). There are currently no known leaks in the system. • Continue to audit, manage and upgrade infrastructure to reduce leaks in the water metering system. Internal Target 2: Improve efficiency of water use on Open Space and City landscaping 22 W-IT2S1: Create a community-wide green infrastructure plan to capture and infiltrate rain water where it falls, thus reducing storm water runoff. This requires a planning process as part of a Stormwater Master Plan. According to one member of the LSAB, this strategy is "complicated due to 'rain barrel' laws in Colorado. The goal with this strategy would be to promote less stormwater runoff directly from pavement to the streams (thus reducing pollution in stormwater) and to have areas designed with plant selection and drainage to allow for reduced irrigation. Rather than treating stormwater as a nuisance that needs to be directed away from City properties or new developments, some water would be put to use or allowed to infiltrate." Interviews with Public Works reveal that a Stormwater Master Plan is on the horizon. Unknown funding required at this time. $150-300K could potentially be largely funded (75%) through a Community Development Block Grant (CDBG). • Plans for a Stormwater Master Plan should be further developed, including a timeline and potential funding source. • The desire to create a community- wide green infrastructure plan to capture and infiltrate rain water should be bookmarked for discussion for incorporation.
