Mississippi Department of Transportation Construction Manual ii INTRODUCTION . This Manual has been prepared to inform and assist construction inspection personnel in the performance of their duties and in the documentation of project activities. This is not a specification Local Project Administration Manual, Chapter 3 - Updated 2019 3-6 3.8 Public Involvement During design, a local agency must give the public an opportunity to learn about potential impacts and comment on a project. An agency should determine an appropriate level of public involvement internal (integrated) dissipators (Chapter 7), stilling basins (Chapter 8), streambed level dissipators (Chapter 9), riprap basins and aprons (Chapter 10), drop structures (Chapter 11), and stilling wells (Chapter 12). Much of the information presented has been taken from the literature and adapted, where necessary, to fit highway needs.
