The City acts as a resource infonnation about xeriscape and <br />efficient irrigation by distributing publications, sponsoring seminars, pub- <br />lishing the daily evapotranspiration (ET) rate and maintaining a xeriscape <br />demonstration garden. <br /> <br />Residential outdoor water use <br /> <br />Ongoing <br /> <br />Water & Power, Parks & Recreation <br /> <br />Homeowners may see a savings of 25 percent of annual water use by in- <br />corporating xeriscape principles in their landscapes. Customers would see <br />reduced water bills and the City would save treatment plant capacity dur- <br />ing peak times. This is a public education measure and it is hard to evalu- <br />ate the savings. <br /> <br />Measure 3: Efficiently irrigate City-owned landscapes <br /> <br />DESCRIPTION <br /> <br />TARGET <br />TIME FRAME <br />STAFF <br />SAVINGS <br /> <br />EXISTING. Parks and Recreation is conscientious about water-efficient ir- <br />rigation of City-owned landscapes. <br />(1) Automatic rain shutoff devices installed on 19 city sprinkler system <br />controllers. <br />(2) Ongoing adjustment of all the controllers and watering schedules. <br />(3) Annual training for irrigation staff. Staff are encouraged to pursue <br />certification through ALeC and IA. <br />(4) Raw water is used for irrigation, where possible. <br /> <br />Outdoor water use at City facilities <br /> <br />Ongoing, watering season <br /> <br />Park & Recreation <br /> <br />In 1996, the City is studying the efficiency of irrigation at city parks. The <br />study will establish a base from which to detennine efficiency and effec- <br />tiveness of water use. Design changes, upgrading pumping systems and <br />new technology may be a result of the study. <br />Currently, of 260 developed acres of parks, public grounds and cemeter- <br />ies, 190 acres (73%) use raw water for irrigation. The three municipal golf <br />courses total about 330 acres, aU of which are irrigated with raw water. Be- <br />cause only 27% of the parks and public grounds are irrigated with treated <br />water, savings at the treatment plant would be minimized. <br /> <br />May /996 <br /> <br />44 <br /> <br />Water Conservation Plan <br />
