BACKGROUND <br />The bocce ball courts at Centennial Park were installed when the park was constructed <br />in 1992. The original court surfacing was an oyster shell and clay soil blend. Over the <br />course of the last 25+ years, the courts have fallen into disrepair as the drainage system <br />installed for the courts has been failing as it has aged. As the court surfacing has been <br />repaired, varying types of bocce ball court surfacing blends were used, including <br />different types of oyster shell, oyster flour, and clay. The drainage problems, combined <br />with the varied bocce ball court surfacing blends, has led to significant problems with <br />the courts, which in turn has affected the use and playability of the courts. The courts <br />flood when it rains, and play can't resume until the courts have sufficiently dried — which <br />is typically several days after a rain event. In addition, the varying court surfacing types <br />used, particularly the large oyster shells, along with damage from the rain/flooding, has <br />led to an uneven and inconsistent surface that is difficult to repair. The easternmost <br />court has been most impacted by the maintenance problems and is often unplayable, <br />leaving the majority of play occurring on the westernmost court. <br />In response to the drainage issues and bocce ball player concerns regarding the courts, <br />the City conducted an evaluation of the drainage system and the bocce surfacing <br />material in early 2018. Upon review, it was determined that the drainage system and <br />surfacing needed to be removed and replaced. During the review, there was also some <br />discussion of additional courts, either at Centennial Park or elsewhere in the City. <br />The City then began to evaluate potential options for renovation or expansion of the <br />City's bocce ball facilities. This included meeting with the City's Bocce Committee, a <br />group of people who regularly play bocce ball on the courts in Centennial Park. City <br />staff also met with the Maintenance Services Supervisor for the bocce facility at <br />Sycamore Valley Park in Danville to review their facility and maintenance practices. <br />With input from the Bocce Committee and from the Town of Danville's Maintenance <br />Services Supervisor, and after exploring costs associated with improvements, it was <br />determined that it would be best to improve the existing bocce ball courts at Centennial <br />Park before considering expansion or additional courts in other parks. The City then met <br />with the Bocce Committee on November 15, 2018, to discuss the scope of work for the <br />court renovation project, which includes new drainage and surfacing, ADA <br />improvements, permanent shade structures, additional seating, and improved lighting. <br />Design work followed the November meeting, with the initial design being presented to <br />the Bocce Committee on January 23, 2019. A summary of that meeting is included as <br />Attachment 1. The updated concept plan and image board is included as Attachment 2. <br />As part of the design process, City staff reached out to other agencies with bocce ball <br />courts and spoke with the Bocce Committee to determine what types of surfacing <br />existed in similar public courts. Based on that communication, the City created the <br />following list of surface types: <br />1. Synthetic turf with infill (sand or rubber) <br />2. Synthetic turf without infill <br />3. EPDM — a synthetic rubber mix similar to the surfacing at Campo di Bocce courts <br />in Livermore <br />4. Oyster shell and flour mix <br />Page 2 of 4 <br />
