In general, the proposal would call for: (1) 100% of <br />water and wastewater charges assessed on the 118 existing metered city services <br />in 1992, (2) 100% of the 83 existing non-metered city services metered and with <br />,100% of water and wastewater charges assessed by 1993, (3) all raw water rented <br />to Parks and Recreation (estimated at 3,200 ac.ft.)at 100% of raw water rental <br />rate by 1992, (4) 100% of conversions to raw water completed, where feasible, <br />for irrigation of Parks and open space by 1994. The total water and wastewater <br />charges for existing city facilities would be in the range of $250,000 to $300,000 <br />by 1993. This amount could be substantially reduced by conversions to raw water. <br /> <br />c) 'Water usage clause in contracts with the contractors who manage irrigation of <br />public landscapes. <br /> <br />The irrigation and maintenance of all street medians, excepting the downtown <br />area, and nine parks is currently contracted out. There is little incentive for <br />these contractors to efficiently irrigate. This is in spite of the fact that these ,are <br />the most visible public irrigation practices, and that any degree of waste results <br />in complaints to the Parks Department or Water Utility. Furthermore, it could <br />probably be assumed that for every citizen that registers, a complaint, there are <br />dozens more who do not speak up but nevertheless hold a negative opinion. <br /> <br />It would be possible to develop contractual text that limits the monthly or annual <br />amount of water that can be used (after meters are installed), witb a penalty for <br />exceeding it and possibly an incentive for lowering it. The reference amount(s) <br />of water could be readily indexed to the particular weather of that year, e.g. more <br />water would be allowed in a hotter and dryer year. <br /> <br />--..,---~--~------ <br /> <br />Approximately 60% of the estimated 710 acre-feet of treated water annually used <br />by the City is for irrigation of public landscaping. Additionally, over 2000 acre- <br />feet of "raw" water is annually used for irrigating public landscapes. As with the <br />residential sector, the greatest potential for increased efficiency is with landscape <br />irrigation. <br /> <br />The existing expertise of the workers responsible for this irrigation could be <br />enhanced with a relatively short training session, perhaps two hours long. The <br />training could be presented by the Parks and Recreation Irrigation Supervisor and <br />the Water Conservation Specialist. <br /> <br />4 <br />
