More than any other profession, civil engineers are concerned with infrastructure, the fabric of urban life. Planning for maintenance and expansion of the nation's infrastructure is the subject of this book. The focus of this manual is the practical use of planning tools to solve real life problems. It provides the reader with a broad overview of the planning process and what factors or issues are of particular concern. The first three chapters deal with planning and the planning process in general, describing the process that any planning study must follow from data collection to implementation. The rest of the book covers urban planning in specific areas including land use, housing, urban transportation, intercity highways, airports, railroads, ports, community services facilities, water resources, parks, wastewater management, solid wastes management, energy, environment, and capital improvement programs.
