For purposes of this report it is assumed <br />that all of these measures will result in a <br />cumulative 50/0 irrigation reduction in existing <br />parks. It is assumed that 70 AFY would be used <br />to irrigate existing parks without conservation <br />measures. <br /> <br />3.5 <br /> <br />:: ~ <br />Landscape and Irrigation Efficiency for Parks <br />Established Parks <br /> <br />Drought resistant vegetation <br />Low water use landscapes <br />Scheduling <br />Moisture Sensors <br /> <br />ET controllers <br /> <br />n/a <br /> <br />n/a <br /> <br />There is a high degree of uncertainty <br />regarding parks development by 2014.
