MATHOT
(August - September 2000)
|
|
The Mathot project
was the Coalition's first stream restoration project and is situated
along Brasstown Creek about 0.4 miles upstream of where Little Brasstown Creek
flows in. The 5-acre tract is owned
by Mitchell Mathot.
Conditions of Site Prior to Project
Because of land use
activities along the stream, including removal of trees on the
streambank and maintenance of a yard up to the edge of the stream,
approximately 820-feet of eroding bank was present along Brasstown Creek
on the Mathot property.
|
Before
Lack of
riparian buffer has caused
significant erosion to property.
|
After
Cross
vane installed to protect both banks. Pool and point bar
were shaped to improve stream features. Bankfull bench was
installed to allow vegetated growth. |
Instream Technologies Applied
Streambank and
channel restoration methods were determined following natural channel
design methodologies as proposed by Rogsen. Procedures included
installation of a cross vane, a wing deflector, and root wads. The bank
was pulled back at a 3 to 1 slope from bankfull to top of bank. See
“As-Built” schematic for details.
Linear Feet of Stream Restoration
820 feet
Linear Feet of Riparian Buffer Restored and/or Protected
1,640 feet
Buffer Vegetation
A 50-foot riparian buffer was established on this site.
A landscape architect was hired to create the landscaping plan and plant
list. During construction, sod mats, shrubs, and trees less than 3” in
diameter were saved for transplanting, where practicable. Potted shrubs
and wetland species were planted along the streambank above
bankfull elevation. Bare root vegetation was planted along the
streambank below bankfull elevation. |
