Illinois Urban Manual
This manual is intended for use as a technical reference by developers, planners, engineers, government officials and others involved in land use planning, building site development, and natural resource conservation in rural and urban communities and developing areas.
The standards and associated materials describe best management practices (BMPs) for controlling non-point source pollution impacts that affect ecosystems in existing communities and developing areas. The manual includes an array of BMPs in the following broad categories:
• soil erosion and sediment control;
• stormwater management; and
• special area protection.
Beyond conventional BMP considerations, the manual addresses fish and wildlife habitat improvement, visual and environmental quality and other relevant ecosystem enhancement applications. Where previous BMP manuals have tended to focus on limited aspects of construction site erosion or stormwater runoff control, this manual is designed for more comprehensive, multi-objective ecosystem protection and enhancement.
This manual supersedes the Illinois EPA’s 1987 “Standards and Specifications for Soil Erosion and Sediment Control” (commonly known as the “Yellowbook”) and the original "1995 Illinois Urban Manual." It also replaces Chapter 6, entitled “Procedures and Specifications”, of the Association of Illinois Soil and Water Conservation District’s 1988 “Procedures and Standards for Urban Soil Erosion and Sedimentation Control in Illinois” (commonly known as the “Greenbook”).
