What is a Wetland?
Wetlands are unique areas! What makes them unique is the presence of
water and the
effect the water has on helping to create one of the most productive
ecosystems in the
world. Because wetlands are either covered or saturated with water for at
least part of
the year, soil conditions are created that help produce a wide variety of
plants that are
uniquely adapted to aquatic conditions. Some wetlands are easy to
identify, such as the
area north of Highway 126 by Fern Ridge Reservoir. This site has an
abundance of water and
water-loving plants, such as cattails and willows, that are typically
found in marshy
conditions. There are other types of wetlands that are not as easy to
recognize, such as
the wet prairie grassland areas north of West 11th and west of Danebo
Street.
A site must have the necessary amount of water (hydrology), type of
soil (hydric), and
type and amount of aquatic plants (hydrophytes) before it is considered a
"regulated" wetland by the Environmental Protection Agency (EPA).
Why are Wetlands Important?
More plant life per acre is present in wetlands than in other North
American
environments. Since wetlands are so productive, they provide valuable
habitat for wildlife
and plants and improve water quality by filtering the water passing
through. They control
flooding by providing an outlet for floodwaters. Wetlands also serve as an
educational and
recreational resource for biologists, birdwatchers, hunters and others.
Why is Wetland Development Regulated?
Development in wetlands is regulated to help preserve their important
functional and
biological values. It is estimated that over half of the wetlands in the
United States
which existed at the time of European settlement were lost by 1975, with
many more acres
drained, dredged or filled since then. Federal legislation places some
wetlands under the
joint authority of the Army Corps of Engineers and the EPA. This
legislation gives these
federal agencies the responsibility of regulating dredge and fill
activities in certain
wetlands to minimize the amount of wetlands lost to development. The State
of Oregon also
regulates fill and removal activities in wetlands through programs
administered by the
Division of State Lands.
Why are Wetlands an Issue?
As a result of studies showing the importance of wetlands and their
loss due to
development, the federal Clean Water Act was amended in 1977 to expand the
definition of
wet areas which are regulated. The EPA administers the Act, and through an
interagency
agreement relies on the Army Corps of Engineers to administer the Act's
permit and
enforcement provisions. A 1977 presidential order further defined the
intent of the Act.
Following amendment of the Act, it took time to prepare regulations,
familiarize people
with them and awaken the rest of the country to the increased importance
of wetlands. Most
major wetlands issues were initially based on the east coast. In the
Pacific Northwest,
the Seattle and Portland areas have been leading the way in dealing with
wetland issues.
Locally, wetlands were not an issue during preparation of the
Metropolitan Plan in the
late 1970s. In fact, the National Wetland Inventory of potential wetlands
in Eugene was
not completed until 1983. Awareness of wetlands increased following a 1985
application for
a permit to fill a pond at a local shopping center. By 1987, State
agencies required the
metropolitan area to show an increased commitment to wetland areas. That
commitment is
expressed in a Plan policy stating:
Local governments shall develop policies and local controls for
protection and
management of wetland areas by completion of the next Metro Plan
Update.
In 1987 work began on updating the areas wetland data base, and the
widespread
existence of wetlands in West Eugene became known. Because there are a
large amount of
wetlands in West Eugene, the Special Area Study process was created to
develop solutions
to wetland concerns.
Wetlands issues are not unique to Eugene or Oregon. Many developers in
the Puget Sound
area must obtain federal wetlands permits in order to develop. The EPA is
supporting
detailed wetland studies throughout the country in order to promote early
identification
of wetland areas and to develop well-planned solutions to wetland issues.
Eugene has
received EPA funding to assist with a portion of the West Eugene Wetland
Special Area
Study.
