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.

The book includes six chapters that cover Virginia history from initial settlement through the 20th century plus one that deals with the important role of underwater archaeology. Written by prominent archaeologists with research experience in their respective topic areas, the chapters consider important issues of Virginia history and consider how the discipline of historic archaeology has addressed them and needs to address them . Changes in research strategy over time are discussed , and recommendations are made concerning the need to recognize the diverse and often differing roles and impacts that characterized the different regions of Virginia over the course of its historic past. Significant issues in Virginia history needing greater study are identified.
