<br />CDM <br /> <br />Section 7 <br />Evaluation and Selection of Conservation Measures and Programs <br /> <br />Erie plans on implementing additional measures to conserve irrigation water. This <br />includes the installation of moisture sensors. These moisture sensors will be installed <br />in all Erie owned parks, shutting off the irrigation system if it is raining. Erie also <br />plans on installing a demonstration evapotranspiration (ET) controller1 at Coal Creek <br />Park. Irrigation at Coal Creek park will be monitored throughout the 2007 irrigation <br />season. If the ET controller is proven to be effective, Erie will consider the installation <br />of ET controllers in additional parks. <br /> <br />Standards Addressing New Parks and Landscaping <br /> <br />As described in Section 2.6, Erie's UDC and Standards and Specifications for Parks <br />and Recreation Construction encourages low water use landscaping designs with <br />water use efficiency as a primary goal for all new parks, recreational facilities, and <br />large HOA common areas. This policy is a proactive approach to incorporating water <br />savings into new development. Erie plans to continue to maintain this policy, <br />promoting efficient water use design in all new development. <br /> <br />7.2.2 Water Efficient Appliances and Fixtures <br /> <br />Fixture Rebate Program <br /> <br />Erie could offer a rebate incentive to encourage customers to replace their older <br />fixtures with ones that are more water efficient. As indicated in Table 7-1, customers <br />could receive a rebate from Erie for the purchase and installation of low-flow toilets, <br />urinals, showerheads, and faucets. This has proven to be effective in older <br />communities where the replacement of high water using appliances and fixtures can <br />provide significant water savings. However, the majority of development in Erie <br />consists of structures that are less than 10 years old. Water fixtures have become much <br />more water efficient within the past decade. <br /> <br />The 1992 U.S. Energy Policy Act established national maximum allowable water flow <br />rate standards for faucets, urinals, toilets, and showerheads. These standards became <br />mandatory in 1994, reducing the flow rates of manufactured faucets, urinals, toilets, <br />and showerheads. Erie's first modern sub-division began construction in 1997. <br />Fixtures installed within these homes complied with the lower flow rate standards <br />and consequently would not yield substantial water savings if replaced. <br /> <br />Erie's old town area consists of approximately 480 older homes. The replacement of <br />older fixtures and appliances in these homes would likely provide water savings. <br />However, these homes currently only comprise approximately 8 percent of Erie's total <br />water taps and this percentage will continue to decrease as Erie continues to develop. <br /> <br />1 ET controllers measure weather indicators to estimate ET rates. An ET rate is the rate of <br />evaporation coupled with plant transpiration. The higher the ET rate, the more water plants <br />need. ET controllers help to ensure that vegetation receives the amount of water it needs <br />without being overwatered. <br /> <br />DRAFT <br /> <br />7-3 <br /> <br />\\DENSVR1\PROJECTS\9228 - ERIE\CONSERVATION PLAN\REPORT\DRAFT PRIOR TO PUBLIC REVIEW\CONNIE FORMATTED\SECTION 7.DOC <br />
