Regularly scheduled maintenance includes:
Courts are pressure-washed once each year in the spring.
Routine maintenance is primarily done between March 1 – November 30, and includes sweeping/blowing off of all courts, general inspection, and removal of any trash, graffiti, and inspection for damage to surfaces, fences, and benches.
Fallen leaves are removed between November and January
Net inspection is done each month, year round. Any problems are repaired or nets/hardware replaced.
Surfaces are crack filled when conditions warrant, and re-sealed approximately once every 10 years, if funding is available. For maximum effectiveness, crack filling can only be performed during warm weather months; primarily between the months of May and September.
