Construction in Floodways of Rivers, Lakes, and Streams Permit Overview

The Construction in Floodways of Rivers, Lakes, and Streams Permit operates within the broader Illinois regulatory framework for water resources management. The permit is administered by the Illinois Department of Natural Resources (IDNR), Office of Water Resources (OWR), which is responsible for managing the state's floodplains and protecting its water resources.⁷

The primary environmental concerns addressed by the permit are the protection of floodplains and the prevention of flood damage. The permit ensures that construction activities within floodways do not increase flood heights or velocities, which could cause damage to property and infrastructure.⁸

The permit was first established in 1971 under the Illinois Construction in Floodways of Rivers, Lakes, and Streams Act. Since then, it has undergone several amendments to strengthen its provisions and align with federal floodplain management requirements.⁹

Which Resources Are Regulated By Floodway Construction Permit?

The Construction in Floodways of Rivers, Lakes, and Streams Permit plays a crucial role in protecting Illinois' floodplains and water resources. The specific environmental resources protected under the permit include:¹⁰

• Rivers, lakes, and streams with a drainage area of one square mile or more in urban areas or ten square miles or more in rural areas.
• The floodways of these water bodies, which are the channels and adjacent land areas that must be reserved to discharge the base flood without cumulatively increasing the water surface elevation.

These resources are protected from construction activities that could increase flood heights or velocities, obstruct flood flows, or otherwise contribute to flood damage. The permit requires that any construction, excavation, or fill within a regulated floodway must be approved by the IDNR and must meet specific engineering and environmental criteria to minimize impacts on flood levels and floodplain functions.¹¹
