Overview of Low-Impact Site Design and Smart Growth Concepts..2-1 Chapter Stormwater Best Management Practices Manual (2007) with Mississippi-specific information where vegetation controls, storm drain flushing, roadway/bridge maintenance, drainage channel, and creek maintenance). Home | Montana Department of Transportation (MDT) This manual has been developed to provide information and guidance to engineering staffs involved with project develop and design of highways. It identifies those standards, specifications, guides, and references approved for use in carrying out the highway and bridge design responsibilities in the Federal Lands Highway (FLH) Program. The Roadway Design Division is responsible for the design and preparation of plans for all projects to construct or reconstruct roadways on the Arkansas State Highway System. The design of these roadways include, but is not limited to, geometric design, hydraulic design, pavement design, and design of sediment and erosion control devices. The 4/3/20.
