Watershed / Riparian Restoration
Evergreen was formed in 2006 by partners each with more than 20
years of experience working for the top environmental
engineering firms in the region. The following projects were
conducted by principals of Evergreen prior to joining Evergreen.
Scenic River Study, Pennsylvania Department of Natural
Resources, Division of Scenic Rivers and Wetlands Conservation,
Tioga County, PA. Conducted a study of Pine Creek to determine
its qualification for entry into the Pennsylvania Scenic Rivers
System. The study entailed a review of the cultural and natural
resources within an 18-mile corridor from Ansonia to Blackwell.
Stream Restoration, Prince George’s County, MD. Remediation
of a small stream stressed by the unmanaged release of storm
water from an existing residential subdivision. The combination
of increased discharge and steep channel gradient have
contributed to headward downcutting of the channel bed, bank
erosion, and downstream sedimentation. Utilized Rosgen stream
classification methods to identify potential restoration methods
for the distressed stream reach. The final design combined
engineered stream meanders and bioengineered bank stabilization
techniques to mitigate the erosive energy of the stream. At
completion, this project will provide Prince George’s County
with a showcase for various restoration methods while fulfilling
the mitigation requirements of the developer.
Anne Arundel County, MD. As required by a Section 404
permit, conducted field investigations of sites identified in
Phase II of the Marley Creek Watershed Assessment. This step
was required as part of developing final design plans,
specifications, and estimates for two proposed projects. Prior
to commencing with final design, coordinated with the regulatory
agencies concerning the suitability of these sites and to
solicit technical input.
Study of the Swan Creek Watershed, Harford County, MD.
Participating in the selection of water quality and stream
restoration sites. Identifying potential wetland impacts,
assessing concept designs, and coordination with state and
federal agencies regarding ability to permit proposed sites.
Bank Navigation and Mitigation Project, U.S. Army Corps of
Engineers, Omaha District, Hamburg Bend, Otoe County, NE;
California Bend, Harrison County, IA; and Langdon Bend, Nemaha
County, NE. Conducted field investigations of wetlands and
other biological resources. Analyzed field, modeling, and
resource agency data to aid in selecting the proposed
alternative which best met the goal of restoring large river
fisheries habitat, chutes, wetlands, and/or migratory waterfowl
habitat. Authored sections of Definite Project Report(s), which
addressed the requirements of NEPA, the Federal Endangered
Species Act, and Section 404 of the Clean Water Act.
Responsible for researching and developing alternatives for
terrestrial habitat and for backwater wetland complexes.
Service, Project Manager. Project Manager of a water
quality study that identified sources of acid mine drainage into
a series of reservoirs used to serve residential customers.
Collected and analyzed lake and stream water samples. Also
initiated correspondence with state-level pollution control
agencies that resulted in remedial action by the State of Ohio.
