Stream Restoration and Banking

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.

The Second Creek Wetland Mitigation Bank, Yadkin River Basin, North Carolina.  Led the permitting, design, construction and planting of a 5000-foot stream restoration and 49 acre wetland mitigation bank located within the Yadkin River Basin, Piedmont Physiographic Region.  Responsibilities included acquiring federal and state permits, banking instrument preparation and approval by the MBRT, and site concept designs.  The MBRT consultations and resultant instrument addressed the bank service area, mitigation credits by quantity and type, monitoring, management, reporting and retirement or final site disposition.  Responsible for restoration success and acceptability by resource agencies, and on-site stream restoration. 
 

Melwood Springs 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.

Engineering 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.

SEQ CHAPTER \h \r 1Stream Restoration and Wetland Creation at the Wyckoff’s 2 Wetland Mitigation Bank, New Jersey.   Managed the restoration of a straight, deep agricultural drainage ditch and the creation of forested wetlands.  Utilized Rosgen method to design an E4 stream for the site.  Managed the completion of a Phase I Environmental Site Assessment survey and sediment analyses to assess site contamination; boundary and topographic surveys; vegetation surveys; hydrologic and hydraulic modeling; geotechnical borings, tests and studies; permit applications; wetland and stream design/build plans; and construction cost estimates.

Wetland and Stream Restoration, Maryland State Highway Administration, Bureau of Landscape Architecture.  Served as Project Manager under several open-end task order agreements related to all aspects of wetlands and stream restoration design.  Duties included identifying potential mitigation sites, ranking sites, and contacting and interacting with property owners to determine their interest in selling/leasing suitable sites to the State.  Developed final design plans, specifications, and cost estimates, prepared permit applications, and conducted post-construction monitoring. 

Warren Street Extension and Relocation/Reconstruction of US 222 Environmental Impact Statement (EIS), Pennsylvania Department of Transportation, District 5-0, Berks County, PA.  Conducted a wetlands study to support environmental documentation for the extension of the Warren Street Bypass and the relocation and reconstruction of S.R. 0222.  Presently coordinating with the U.S. Army Corps of Engineers and the Pennsylvania Department of Environmental Resources regarding the selection of candidate sites to provide approximately 20 acres of forested, scrub-shrub and emergent wetlands creation and enhancement for sites to composite for 6,000 lf of stream channel impacts.

Washington Post Facility Wetland Mitigation.  Completed a wetlands delineation and obtained authorization to relocate a small on-site stream.  Established design criteria and developed conceptual alternatives using Rosgen Classification System and bioengineering techniques for the new stream channel design.  Developed and incorporated wetland vegetation planting plan into the project plans.  Provided construction and inspection monitoring during the channel construction phase of the project and during the planting phase. Obtained required permits.
