Bill > SB1595

This bill amends the Rivers, Lakes, and Streams Act to establish new requirements for the Department of Natural Resources (DNR) when reviewing construction projects in flood-prone areas. The bill defines several key technical terms, including "base condition" (the current pre-permit levee elevation profile), "induced head" (changes in water surface profile and water elevations), and "worst-case analysis" (flood events with up to a 1% annual chance of occurrence, also known as a 100-year flood). The bill mandates that for construction related to these potential flood events, the DNR must: (1) provide submitters with a detailed permit review process within 90 days, (2) allow a 0.5-foot water surface profile increase for rural construction along navigable waterways, (3) allow a 0.1-foot water surface profile increase for urban construction, and (4) only require a mitigation analysis if the proposed water surface profile increases exceed the results of an induced head study. These provisions aim to streamline the permitting process for flood-related construction projects while maintaining environmental safeguards.
