19. Minor stormsewer outfalls within the road right-of-way may be permitted under this general permit, provided that the structure will have minimal impacts to the waterway or wetland and BMPs are used in design and placement of the structure. 20. Ditch maintenance may be permitted under this general permit provided that the dimensions of the ditch are not being altered and best management practices (BMPs) are used to comply with water quality standards. 21. Flood Resiliency — Structures over navigable waterways must be sized and set at an elevation so that water depths, widths and velocities at the inlet and outlet match the natural stream channel. Invert elevations of culverts will be determined by surveying the stream upstream and downstream and setting the culvert below the natural flow line. 22. The project shall not result in a material obstruction to navigation, and must allow for portage to anyone legally navigating the waterway. All bridges and culverts shall either maintain a clearance of not less than 5 feet above the ordinary high water mark (OHWM), or comply with requirements of Wis. Admin. Code NR 320.04(3). 23. To minimize adverse impacts on fish movement, fish spawning, and egg incubation periods, work in the waterway may not take place during the following periods, unless modified by the Transportation Liaison, who will coordinate with the DNR Fisheries Biologist: • September 15th through May 15th for all trout streams and upstream to the first dam or barrier on the Root River (Racine County), the Kewaunee River (Kewaunee County), and Strawberry Creek (Door County). To determine if a waterway is a trout stream, you may use the WDNR website trout maps which can be found at http://dnr.wi.gov/topic/fishing/trout/streammaps.html. • March 1 st through June 15th for ALL other waters. 24. For projects located in an area that is known for wildlife movement or migration, the applicant has coordinated with the Transportation Liaison to use BMP's to provide habitat connectivity in the design and construction of the project.
