Street maintenance involves Mt. Lebanon's responsibility to maintain approximately 78 miles of municipal streets and paved alleys, including street resurfacing, joint sealing, brick and concrete roadway repairs and maintenance of guardrails.
Only emergency repairs of concrete, brick and asphalt streets take place. Municipal crews patch all holes with a year-round maintenance contract covering larger patching. Winter patching with cold material is done on an emergency basis.
Contractual repair of 60,000 square feet (.4 miles) of the most seriously deteriorated streets in the community. This includes work on concrete streets (50 percent) and bituminous streets (50 percent). Concrete slabs are replaced and three-inch bituminous overlay is applied. Municipal crews repair signs and guardrails, and do minor asphalt repairs.
Additional streets in need of repair are serviced by contract on a systematic basis, with those in the worst condition given priority. About 90,000 additional square feet (.6 miles) of concrete and bituminous streets are repaired, continuing the percentage breakdown established for the basic repair.
