Adequate drainage provides for continuous, safe, all weather highway use. Further, proper roadway drainage prevents erosion, flooding, and disastrous washouts. Increased land development and improved transportation are resulting in accelerated runoff and altered natural drainage patterns. This guide is developed to assist local officials in efforts to develop rational plans for roadway drainage. It provides the county engineer with a format for the investigation of existing drainage patterns, analysis of rainfall frequencies and intensities, determination of probable flow requirements, hydraulic design of the necessary channels, conduits and structures, and the legal implications of artificial drainage systems. Stormwater management is also addressed. To simplify the use of this guide, an extensive glossary of terms, charts and tables, and design data are included.
