Q1. What are wetlands?
A. Wetlands are those areas of land transitional between terrestrial and aquatic systems where the water table is usually at or near the surface or the land is covered by shallow water. Wetlands are specifically identified by using the 1987 Army Corps of Engineers Wetlands Delineation Manual to identify wetland plants, wetland soils, and wetland hydrology. More information (MN Board of Water & Soil Resources)

Q2. So, there are no cattails, so it’s not a wetland. Right?
A. Wrong. There are several different types of wetlands that are not open water marshes. In St. Louis County some of our most common wetlands are shrub and forested wetlands. More info (DNR types of wetlands)

Q3. Is a wetland always wet?
A. No. See Q1 above. There are several different types of wetlands. Some wetland types may never have standing water, but water is near enough to the surface for a long enough period of time to support wetland plants and create wetland soils. More info (MN Board of Water & Soil Resources)

Q4. Do I have wetlands on my property?
A. We don’t know. We have access to National Wetland Inventory (NWI) maps and aerial photography that can help agency personnel or individuals get an idea if wetlands are present. But wetlands need to be identified in the field. See Q1 above. From our experience, the NWI maps almost always understate the area of wetland that actually exists. More info (US Fish & Wildlife's National Wetland Inventory)

Q5. How do I know for sure where wetlands are on my property?
A. If you are anticipating a project that could impact wetlands, getting a wetland delineation for the property in advance of applying for permits could save you a lot of problems in the long run. A wetland delineation is report based on a field investigation completed for an area of land that contains a map of wetland and upland areas plus data sheets that document the presence or absence of wetland indicators. See QI above.

Q6. How do I get a wetland delineation?
A. A wetland delineation is typically prepared by a private consultant that a landowner hires. Available wetland delineators may be found in the phone book. The SWCD and U.S. Army Corps of Engineers maintain lists of contractors available on the internet. More info (pdf of consultant list, as of Sept 2012)

Q7. Are wetlands regulated and protected?
A. Yes. The Minnesota Wetland Conservation Act (WCA) dictates that generally no person shall drain, fill, or otherwise impact any type of wetland, or excavate in the permanent or semi-permanently flooded areas of type 3, 4, or 5 wetlands without first having a wetland replacement plan or other determination approved by the local government unit. The U.S. Army Corps of Engineers also regulates wetlands by implementing the Clean Water Act.

The Minnesota Department of Natural Resources regulates some wetlands that are Public Waters. More info (at MN Board of Soil & Water Resources forms and guidance) and U.S. Army Corps of Engineers wetlands permiting

Q8. So what if a road, building or other structure has to be built over wetlands? Does the WCA prevent all impacts to wetlands?
This project was funded in part under the Coastal Zone Management Act, by NOAA’s Office of Ocean and Coastal Resource Management, in cooperation with Minnesota’s Lake Superior Coastal Program

A. The Wetland Conservation Act and federal wetland rules provide a process that allows some development in wetlands, while avoiding and minimizing wetland impacts. Some wetland impacts also require wetland mitigation or replacement wetlands so a no-net loss of wetland quantity and quality is achieved. Almost any wetland impact greater than 400 square feet requires prior approval. The Wetland Conservation Act does have several exemptions that could apply to your project, meaning in limited circumstances wetland impacts could occur without local government approval. However, the U.S. Army Corps of Engineers also regulates wetlands in Minnesota. There are no exemptions under the federal rules that allow impacts greater than 400 sq. ft. without prior notice and approval. In addition, some communities have their own wetland management plans that regulate wetlands above the standards of the WCA

Q9. So a project will impact wetlands. What do I do?
A. Early in your project planning submit a Minnesota Local/State/Federal Application Forms for Water/Wetland Projects. Instructions are included with the application. The application is submitted to the Local Government Unit (LGU) that has jurisdiction over the wetland project, the DNR, and the Army Corps of Engineers. The LGU is the county or city where the project is located. Townships with their own zoning authority are not WCA LGUs. Contact the SWCD if you are not sure where to send the application. Download applications (MN Board of Water & Soil Resources forms and guidance)or pick them up at the SWCD office in downtown Duluth. More info (DNR's St. Louis County info page)

Q10. So it’s the Minnesota Wetland Conservation Act, but I have to work with local government?
A. Yes. All WCA determinations and approvals are made locally. All applications are sent to the Local
Government Unit, DNR and Army Corps of Engineers. Contact the SWCD for help determining your WCA LGU.


Q11. I’ve heard I can fill in 10,000 square feet of wetland without approval. Is that true?
A. Not completely. A project may be eligible for an exemption under the WCA; however exemptions can be complicated and may only apply to certain types of wetlands in certain locations. Plus, prior approval from the U.S. Army Corps of Engineers is still needed even for WCA exemptions. More info (MN Board of Water & Soil Resources forms and guidance)

Q12. So I got a culvert permit to put in a driveway. Does that mean all wetland impacts are also approved?
A. No. A culvert permit does not authorize the filling of wetlands. Also, a building permit from a township
zoning office does not authorize wetland impacts. Authorization for wetland impacts comes only from the WCA LGU (St. Louis County or city where the project is located) and the U.S. Army Corps of Engineers. You must specifically apply to impact wetlands.


Q13. What if I get a permit for a septic system? Are wetland impacts automatically approved?
A. No. See Q12. It can be confusing, but there are separate permit processes.

Q14. Can I dig a pond in a wetland?
A. Maybe. Excavation in type 1, 2, 6, 7, 8 wetlands is not regulated by WCA, as long as the excavation is not greater than 2 meters (6.6 feet), no draining of the wetland occurs, and no spoils or excavated material is placed in a wetland. However, in most instances, written authorization from the U.S. Army Corps of Engineers is required for ponds constructed in wetlands. See Q9 above for an application. More info (DNR wetland types and technical specs)

Q15. I’m thinking about buying property. How will I know if there will be wetland issues?
A. Make sure that you inspect the property during the wettest time of the year. Ensure that the property is suitable to whatever your potential plans may be. One could ask the seller to produce an approved wetland delineation prior to closing on the property. National Wetland Inventory maps and aerial photos could be reviewed. If in doubt, ask the LGU, SWCD, U.S. Army Corps of Engineers, or a qualified consultant. See Q1-6 above.

Q16. Where can I get more information?
