Of Stream Stability Restoration Demonstration Project In Broadstreet
Joel A. Miele Sr., P.E., of the New York City Department of Environmental
Protection (DEP); Reneé VanSchaack, Executive Director of Greene
County Soil and Water Conservation District (GCSWCD); and Gary Capella,
Executive Director of Ulster County Soil and Water Conservation District
(UCSWCD); announced today the completion of the stream stability restoration
demonstration project on the Broadstreet Hollow Stream in the Town
of Lexington, Greene County. This construction project is part of
a much broader effort to develop the "Broadstreet Hollow Stream
Management and Restoration Project," spearheaded by DEP's Stream
Management Program and UCSWCD to develop a comprehensive stream management
plan for the Broadstreet Hollow within Greene and Ulster Counties.
Funding for the demonstration project has been provided by DEP; the
Army Corps of Engineers (ACOE), under the Watershed Environmental
Assistance Program; the National Fish and Wildlife Foundation; and
the Ashokan-Pepacton and Catskill Mountain Chapters of Trout Unlimited,
through a National Trout Unlimited "Embrace a Stream" grant.
project represents the culmination of many months of cooperative effort
undertaken by multiple agencies, organizations and landowners, all
with common goals of improving water quality, enhancing aquatic habitat,
reducing flood risks and maintaining stream channel stability and
the special qualities of natural stream resources in the Catskills,"
said Commissioner Miele. "We are pleased to be a partner in this
project, and look forward to continued success in the implementation
of the stream management plan in the coming year."
Development of Stream Management Plans is a new approach to stream
management in the Catskills. The Broadstreet Hollow plan will be a
comprehensive document, developed in cooperation with landowners and
local interest groups, town and county governments, and State and
federal agencies. As part of the overall project, the Broadstreet
Hollow stream will be surveyed for problems over the entire corridor.
The completed plan will provide a blueprint for addressing stream
related issues, from restoration and emergency response to effective
development planning and long term resource stewardship, as well as
a headwaters-to-mouth management framework that encourages community
involvement and cooperation.
just-completed demonstration project included a full-scale channel
reconstruction, which returned nearly 1,100 feet of over-widened and
badly eroding stream to a stable, naturally functioning step-pool
channel. The new configuration is more suitable to the narrow valley
and geologic setting of Broadstreet Hollow and provides much better
habitat for the native populations of brown, rainbow and brook trout
historically supported by this stream.
"The Broadstreet Hollow project presented some of the most
difficult site conditions we have addressed on a restoration site
to date," said Doug DeKoskie, Stream Program Leader for GCSWCD.
"The design had to address development of a stable stream channel,
flood protection for the adjoining residences, stabilization of a
failing hill slope and an artesian 'mud boil' in the stream bottom."
addition to the channel construction itself, a critical project component
is the process known as 'bioengineering,' which uses plant materials
to assist in streambank stabilization," said Reneé VanSchaack
of GCSWCD. "In our experiences constructing this kind of stream
restoration project, we've seen that the vegetation component really
sets the project up for longer-term stability, just like in naturally
stable streams. Without it, the project just isn't finished."
"The restoration project site, characterized by a tremendous
amount of thick, soft glacially deposited clay that makes up the bed,
banks and surrounding valley walls, typifies conditions found naturally
throughout the Esopus and Schoharie Creek watersheds," said Gary
Capella, of UCSWCD. "This restoration project provided a unique
opportunity for us to address the problem of the glacial lake clays
on a small scale. I am hopeful that we may use these techniques throughout
the Esopus and Schoharie Creek watersheds, where there are many more
eroding sites producing high turbidity, just like this site was before."
