Stream Services
Alliance's services include biological and morphological assessment of
streams; natural channel design; mitigation plan preparation, permitting and agency coordination;
construction oversight of channel restoration; and monitoring of project success.
We have performed hundreds of miles of stream delineations. Our personnel
are familiar with many state as well as regional requirements for delineations services To improve
efficiency in conducting stream delineations, Alliance’s field scientists conduct GPS surveys of the
boundaries using a differential GPS unit capable of sub-foot accuracy. Alliance personnel have the
expertise to participate in Jurisdictional Determinations (JD) field meetings with the U.S. Army Corps
of Engineers to validate the delineated stream and wetland boundaries.
Our Services:
- Stream-Type Determinations
- Stream Delineations and Surveying
- Boundary GPS Surveys
- Jurisdictional Determinations (stream boundary confirmation)
- Stream Flow Monitoring
- Stream Flow Remediation
Our experienced personnel utilize state of the art electronic flow
meters having a digital display of stream velocities. Alliance is uniquely qualified in
collecting flow measurement to evaluate stream flow conditions along more than 100 miles of
streams with underground mining beneath/ or immediately adjacent to them. All of our stream
flow measurements are performed in accordance with the United States Geologic survey (USGS) protocol.
Stream flow remediation techniques have included streambed grouting by use of hydrophobic
polyurethane and the installation of low and/or high density polyethylene liners with aquatic
habitat reconstruction in stream overtop these installations.
Our People:
Alliance has performed stream flow studies, prepared stream flow restoration plans,
given formal presentations regarding stream flow restoration techniques and supervised field activities
associated with stream remediation on numerous projects. To date our largest single project consisted of
over 6,200 linear feet of remediated watercourses in a watershed in Marion County, West Virginia.
