<br />construction and replacement fixtures, The city is also proposing a <br />showerhead replacement program for 1997 to encourage and accelerate <br />the voluntary replacement of old showerheads with the new 2.5 <br />gallons/minute, fixtures. The new program proposes to reimburse <br />Broomfield residents up to $5 per showerhead replaced with a new water- <br />efficient showerhead, <br /> <br />The city's new municipal center (administration, police and library), water <br />treatment plant and field maintenance facilities have been or will be <br />constructed with the required water efficient fixtures, The water treatment <br />plant staff is proposing to conduct water audits at the remaining facilities <br />to determine the extent of the need for retrofit and to provide educational <br />materials to city employees at each facility, The retrofit may be phased <br />over a 5 year period. <br /> <br />2, Low water-use landscapes and efficient irrigation: <br /> <br />Policy 2.5 of the City's master plan states that open space landscaping <br />should emphasize the use of drought tolerant, non-invasive plant species, <br />The design and maintenance of landscaping must recognize the ultimate <br />conditions of a specific location and provide appropriate plantings which <br />can survive and regenerate naturally. <br /> <br />The city's planning department is reviewing landscaping specifications for <br />city-wide median landscaping, A range from green landscapes to <br />Xeriscapes is in their evaluation, <br /> <br />The city's park irrigation system is 100% metered, The parks <br />maintenance department has a computerized irrigation system, COPS <br />Universe, that IS linked to a weather station at the city's wastewater-U <br />treatment plant. The system uses IrriCalc software to determine how <br />much water is needed for the parks system, The irrigation circuits are <br />remote controlled by radio signals sent out from the base computer, The <br />software factors in current evapo-transpiration (ET) rate, historical ET <br />rate, soil condition and type, turf type, and efficiency of sprinkler heads in <br />the park of interest to determine the frequency of irrigation and the <br />amount of water applied. The irrigation programs run through the night to <br />reduce evaporation, The city also aerates the park's turf twice a year <br />(athletic fields three times per year) to make irrigation more efficient. The <br />system will shut down irrigation during precipitation events and when the <br />wind blows greater than 15 miles per hour (20 miles per hour in more <br />protected areas), The parks department estimates that they apply 1.5 <br /> <br />14 <br />
