East Portal Bocce Court Construction
Photos courtesy of John Ross. They first appeared in Vol. II, Issue 18, May 5, 2003. They now are a permanent part of Bocce Venues. The two courts are 90' by 12' at the East Portal Bocce Club in Sacramento, California. Most of the construction took place in 2003 by East Portal Club members and the US Bocce Federation.
There are two smaller existing courts that are used year round because of the roof above.
John Ross says "Formwork for the new concrete is being installed. The East Portal club house is in the background. The center curb in this photo is 10 inches wide which provides a comfortable place to stand while avoiding an incoming raffa shot. No drainage system under the courts is required because of the roof, and positive surface drainage away from the courts."
According to Ross, "This is a view from the club house looking at the two structures and courts. The new courts are to the right."
"Concrete has been placed and the forms have been removed. The forms will now be used for the side boards and to repair the two existing courts."
"The base rock (2") was installed and compacted over the native compacted clay. Then 4" of granite fines were placed over the base rock in 1" lifts moistened, and compacted with a vibratory plate. The granite fines are a by product of the rock crushing machine at the quarry and range in size from dust to about the size of a beebee. Because the fines come from the crushing process, they have sharp broken edges and when compacted, lock together to form a very dense base. Oyster shell flour and sand was then used for the finished playing surface. Oyster shell flour is a natural source of calcium. Over time the calcium penetrates the top strata of the granite fines and binds the playing surface with the granite base providing an excellent playing surface."
"View of the north end of the finished courts showing the great ball rack and bleachers. The ball rack has a locking cover which provides secure storage for the balls and pallino. The green box to the left provides storage for the 'left over' granite fines for future maintenance and court repair. The side boards have been painted green and the end boards swing and are covered with rubber. The box on the curb is a window screen sieve. Each time the court is swept and cleaned, the debris is sifted. Over time this removes the larger shell and granite particles, leaving behind a very fine top playing surface."
