Box 66 <br /> Orono, MN 55356 Crystal Bay, MN 55323-0066 <br /> Wetland Alteration Guidelines: Excavation of Ponds <br /> 1. Excavation of ponds in upland areas (not within nor within 26' of a Type 1 thru Type 8 wetland) <br /> requires a staff-issued land alteration permit if not more than 500 cubic yards, and a Conditional Use Permit <br /> (CUP) if more than 500 cubic yards. Such grading may require a permit fom the MCWD. <br /> 2. Excavation of a pond in a WCA wetland that is not a City-protected wetland, will require MCWD <br /> approval as well as a City land alteration permit (and a CUP if over 500 c.y.), and may require U.S. Army <br /> Corps of Engineers approval. <br /> 3. Excavation of a pond in or within 26' of a City-protected wetland, will require a Variance and <br /> Conditional Use Permit approval regardless of the amount of excavation; likely will require MCWD and <br /> Corps approval; and may require DNR approval if it is a DNR-protected wetland. <br /> 4. City approval of pond excavations will take into account the applicable requirements and review <br /> considerations as defined in Zoning Code Sections 10.55 and 10.56. <br /> 5. The City will generally not approve a Var/CUP application for a decorative pond in City-protected <br /> wetlands unless such pond is designed to meet minimum wildlife habitat specifications, which generally <br /> include: <br /> - Pond surface area of at least 2500 s.f. - 10:1 perimeter bench to a 1' depth <br /> - Depth of approximately 4-5' - Excavating a small portion of a larger wetland <br /> 6. Approval for ponds excavated in City-protected wetlands will normally require the use of erosion <br /> control measures,vegetation restoration,and the granting of a conservation and flowage easement to the City. <br /> 7. Information required in order to make application for a Var/CUP for pond excavation includes but is <br /> not limited to: <br /> - Complete General Land Use Application with fee/property owner list/plat map <br /> - Property survey <br /> - Wetland delineation report(must use a professional delineator) <br /> - Grading plan(existing and proposed contours) <br /> - Vegetation restoration plan <br /> - Indication of spoil disposal site <br /> Glossary: WCA: Wetlands Conservation Act MCWD: Minnehaha Creek Watershed District <br /> DNR: Minnesota Department of Natural Resources var: variance CUP: Conditional Use Permit <br /> Telephone(952)249-4600 • Fax(952)249-4616 <br /> www.ci.orono.mn.us <br />
