6: / ¿ .,e/ . Hawes Park (entire park) . Hoover Park (4 acres) . Sequoia High School (2.2 acres) . Cañada College (2.5 acres) The Task Force estimated that turf conversion of natural grass playing fields to synthetic turf would reduce potable demand by a total of 150 af/yr. Status: The playing field at Sequoia High School was converted to synthetic turf in the summer of 2002, reducing potable demand by an estimated 6 af/yr. The Hoover Park playing field was converted the synthetic turf in October 2002. Based on water use data from the park's water meter, the City has conserved about 9 af/yr of potable water. Two playing fields at Cañada College are currently being converted to synthetic turf, with estimated completion in summer 2005. At the time of the Task Force report, Cañada College was planning to install synthetic turf on the soccer field only. Subsequently, the College added a baseball field to the turf conversion contract. The total area of conversion is approximately 5.2 acres, an increase of 2.7 acres over the estimate included in the Task Force report. This increases the total estimated potable demand reduction at Cañada College to approximately 33 af/yr. At this time, no other fields at the College are scheduled for conversion to turf. Work Plan Next Steps: In July 2005, the City plans to begin design of three synthetic turf fields in the Red Morton park complex, with bidding and contract award scheduled for January to March, 2006. Construction of the three fields will require approximately one year. Turf replacement at Sandpiper Park, Marlin Park and Hawes Park is scheduled for bidding and construction in the spring of 2007. 2.1.3 Existing Groundwater Use Recommendation: Maintain existing potable water demand reduction by continuing to use groundwater to irrigate Sequoia High School landscaping. This recommendation is estimated to reduce potable water demand by 57 af/yr after the playing field is converted to artificial turf. Status: Sequoia High School is continuing to irrigate with the existing groundwater system. The Task Force Report had assumed that the high school was using groundwater to irrigate the entire site. However, the City subsequently determined that the consumption of potable water for outdoor irrigation averages 13,000 units (or 30 at) per year. Therefore, the total potable water savings by irrigating with groundwater is now estimated to be 27 af/yr. Work Plan Next Steps: The school will continue to irrigate with groundwater, provided the well continues to produce sufficient quantity and quality of water. Within the next year, the City will initiate further discussions with district operations staff to ensure the site is maximizing the use of groundwater for landscape irrigation and to evaluate the entire irrigation system for efficiency and optimization of water use in accordance with BMP 5.
