When you're buying vacant land with the hope of developing it in the future, wetlands can present some pretty significant challenges.
Wetlands are protected by the federal government (and often by the state government as well) because even though this type of land may seem useless to the average landowner, it serves many important purposes for people, fish, and wildlife.
This excerpt from the EPA sums it up pretty well…
Wetlands are important features in the landscape that provide numerous beneficial services for people and for fish and wildlife. Some of these services, or functions, include protecting and improving water quality, providing fish and wildlife habitats, storing floodwaters and maintaining surface water flow during dry periods.
Because wetlands are such a valuable natural resource, most governmental bodies are understandably interested in preserving this type of land whenever possible.
For most intents and purposes, if a parcel of land contains any type of wetland area, that portion of land cannot be built on or developed without special permission from at least one, if not multiple government authorities.
For land investors doing research on a parcel prior to purchasing – finding and identifying the presence of wetlands can be particularly challenging, because as the EPA explains:
Although wetlands are often wet, a wetland might not be wet year-round.
In fact, some of the most important wetlands are only seasonally wet.
Types of Wetlands
First off – it's important to acknowledge that in many cases, wetland areas CAN be easily seen and identified.
In the United States, there are four commonly known categories of wetlands:
This type of wetland is often populated by soft-stemmed plants (e.g. – grasses, rushes or reeds) and situated alongside lakes and streams. Marshes function as a transition point between the aquatic and terrestrial ecosystems. There are several types of marshes that differ based on their location and salinity, which also affects the type of animal and plant life that can live in these environments. (source)
Typically dominated by woody plants, and sometimes described as “forested wetlands”. Many swamps are situated along rivers, where they are critically dependent upon natural water level fluctuations. Other swamps occur on the shores of large lakes. Swamps are characterized by slow-moving to stagnant waters, in areas at a very low elevation. (source)
Swamps and other wetlands have traditionally held a very low property value compared to fields, prairies, or woodlands. They have a reputation for being unproductive land that cannot easily be utilized for human activities, other than perhaps hunting and trapping. (source)
Bogs are freshwater wetlands, often formed in old glacial lakes, characterized by spongy peat deposits, evergreen trees and shrubs, and a floor covered by a thick carpet of sphagnum moss. (source)
Similar to marshes, there are several different types of bogs, that can be classified based upon their location in the landscape, and their source of water. Bogs are widely distributed in cold, temperate climes, mostly in boreal ecosystems in the Northern Hemisphere. (source)
Fens are freshwater peat-forming wetlands covered mostly by grasses, sedges, reeds, and wildflowers. (source) They may also occur along large lakes and rivers where seasonal changes in water level maintain wet soils with few woody plants. (source)
The problem with the EPA's definition of wetlands is that it leaves plenty of room for ambiguity.
Even though wetlands are often characterized by marshes, swamps, bogs, and fens, wetlands don't always have an observable presence of water on or near the surface.
Take the Florida Everglades, as one example.
Depending on the time of year, huge portions of this 734 square mile wetland area are often dry.
Now take a look at your own backyard after a rainstorm. You may easily be able to spot pooling water near your house… but that doesn't mean you live in a wetland area.
How to Identify the Presence of Wetlands
If you or your future buyer have any concerns about the presence of wetlands on your property, there are two things to consider:
- Wetland Identification: This is simply the determination of whether or not an area is defined as a wetland.
- Wetland Delineation: This is the actual establishment of wetland boundaries – where the wetland area begins and ends.
If a land owner's activities or improvements to the property will impact the function of the wetland area, then both the wetland identification AND delineation are very important. Unfortunately, both of these things can be complicated and require some technical knowledge.
In many areas of the United States, there is at least one (and often more than one) government entity that plays a role in delineating wetlands.
At the federal level, the U.S. Environmental Protection Agency (EPA) and U.S. Army Corps of Engineers (USACE) are key players in delineating wetlands, with additional input from the U.S. Fish and Wildlife Service (FWS) and the Natural Resources Conservation Service (NRCS).
In most states, the U.S. Army Corps of Engineers has the authority over the permitting process – as stated on the USACE website:
“Section 404 of the Clean Water Act requires that anyone interested in depositing dredged or fill material into “waters of the United States, including wetlands,” must receive authorization for such activities. The Corps has been assigned responsibility for administering the Section 404 permitting process. Activities in wetlands for which permits may be required include, but are not limited to:
- Placement of fill material.
- Ditching activities when the excavated material is sidecast.
- Levee and dike construction.
- Mechanized land clearing.
- Land leveling.
- Most road construction.
- Dam construction.
The final determination of whether an area is a wetland and whether the activity requires a permit must be made by the appropriate Corps District Office.”
In my state (Michigan), development of any wetland areas near “navigable waters” requires a delineation and permit from BOTH the U.S. Army Corps of Engineers (USACE) and the Michigan Department of Environmental Quality (MDEQ). These permits generally involve a lot of red tape – and in most cases, unless the landowner can prove there is no other alternative to accomplish their intent, they simply aren't issued at all.
Given all the complications of dealing with wetlands, most land investors would rather avoid these types of properties altogether – because it's pretty counterproductive to buy a parcel of land that can't be used in any practical way. This is why it's important to identify the presence of wetlands BEFORE closing the deal.
Is There An Easier Way?
Ultimately – the only way to be 100% confident about the presence of wetlands on a property is to enlist the help of a wetlands consultant and/or have the appropriate government agents conduct their wetland identification and delineation on-site.
The problem is, this is a lot to ask. Especially when a property is being bought at a small fraction of market value and the transaction needs to close quickly. This kind of “textbook answer” on how to research the wetlands situation isn't always the most pragmatic solution.
So is there any feasible way to get these answers faster? Well… sort of.
If you want to identify any obvious red flags without leaving your computer, it is possible to do some reconnaissance-level research and get a more educated look at the wetland situation on your subject property. I'll explain one method in this video…
Now, since the wetlands mapper isn't always the most accurate measurement of the presence of wetlands, another tool you can use to assess the situation is the NRCS Web Soil Survey, which is compiled by the UC Davis Soil Resource Lab.
You can download this SoilWeb KML file by visiting the Google Earth Library.
Keep in mind, using the Wetlands Mapper and/or the Web Soil Survey is NOT the same thing as hiring a wetlands consultant and/or having the USACE do a delineation on your property (so realize, there are no guarantees with this approach). However, if you're just looking for an educated guess, both of these online tools can be used as a good starting point.
