Since the surveys produced such conflicting results, staff reached,out to other agencies, as well as consultants and contractors, to determine costs associated.with each type.of surfacing. Staff requested information about the cost of installation, the cost of day-to- day maintenance and.the replacement costs. Staff also researched manufacture and .other information .online to understand expected replacement frequency for each surface type. Since the frequent maintenance of the oyster -shell and flour surfacing options includes material replenishment, these materials do not have to be "replaced:" The synthetic turf, which was used at the Livermore and Foster City courts, -and EPDM, .which was used at the San Carlos courts, have to be replaced every &10 years. For ease of comparison the estimated costs of each surface. material is listed in the table below (based upon two courts): Upon review of maintenance and replacement considerations, and the surfacing survey results, the City's primary concern remains specifying a court that can adequately be maintained at a consistent level. The EPDM surface provides the lowest level of maintenance with the most consistent level of play. While it is shown in the table above to have the highest "total cost" when including the.replacement costs, staff is _recommending EPDM as the -surface material to use in. this project. Public EPDM courts are. located in. San Carlos and San Mateo, which have staffing levels similar to,. or more limited than, Pleasanton. Public courts with oyster shell and flour blends typically have a dedicated maintenance person or crew that is primarily funded by the bocce league, which is not the case in Pleasanton. City staff if presenting this information to the Parks and Recreation Commission and seeking approval of moving.forward .with the EPDM surface material as recommended.
