This report further develops a framework for measuring and monitoring performance in key federal infrastructure programs. It represents an update to the work of the National Council on Public Works Improvement in preparation for the issuance of Fragile Foundations (1988). Performance is defined, measurable aspects of performance are identified, and data on these aspects are then presented, qualitatively and quantitatively, for three infrastructure categories: (1) transportation, (2) water resources, and (3) waste management. The specific programs covered are: (1) aviation; (2) highways; (3) mass transit; (4) water resources; (5) wastewater treatment; (6) public water supply; (7) solid waste management; and (8) hazardous waste management.
