The rapid conversion of land to urban and suburban areas has profoundly altered how water flows during and following storm events, putting higher volumes of water and more pollutants into the nation's rivers, lakes, and estuaries. These changes have degraded water quality and habitat in virtually every urban stream system. The Clean Water Act regulatory framework for addressing sewage and industrial wastes is not well suited to the more difficult problem of stormwater discharges. This book calls for an entirely new permitting structure that would put authority and accountability for stormwater discharges at the municipal level. A number of additional actions, such as conserving natural areas, reducing hard surface cover (e.g., roads and parking lots), and retrofitting urban areas with features that hold and treat stormwater, are recommended.

Tunnels represent a significant financial investment with challenging design, construction, and operational issues. Tunnels that are not adequately maintained usually require more costly and extensive repairs. To help safeguard tunnel users and to ensure reliable levels of service, the FHWA developed the National Tunnel Inspection Standards (NTIS), the Tunnel Operations Maintenance Inspection and Evaluation (TOMIE) Manual, and the Specifications for National Tunnel Inventory (SNTI). In accordance with the NTIS, this Manual describes methods for improving the safety and performance of roadway tunnel operation, maintenance, inspection, and evaluation programs.

Details the rationale behind grades in 15 categories as announced by ASCE. This book presents an analysis of each category, an assessment of your state's status, case studies of successful projects, suggestions for actions you can take and ways you can get involved, and more.

This roadside safety design package has been developed to satisfy a need for training in this area. It is hoped that all persons involved in the design, construction, operation, and maintenance of highways will become familiar with the concepts contained in the program. The concepts and practices discussed come from those contained in the AASHTO publication, "Highway Design and Operational Practices Related to Highway Safety". They are discussed in considerable depth in this program and should provide a good working knowledge of roadside safety design. Much of the program is oriented around freeways; however, the principles apply equally toward the lower order highway.

Social justice is a matter of life and death. It affects the way people live, their consequent chance of illness, and their risk of premature death. We watch in wonder as life expectancy and good health continue to increase in parts of the world and in alarm as they fail to improve in others.
