Wetland Mitigation Design and Permitting


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.


US Army Corps of Engineers, New York District, Tidal Salt Marsh Restoration Design and Feasibility Study for Gerritsen Creek, Brooklyn, New York. Managed ecological analysis and design of 67-acre tidal salt marsh estuarine system and coastal grassland area. Tasks included review and QA/QC with Corps and non-federal sponsor on the preliminary restoration design alternatives, habitat evaluation using EPW, development of Feasibility Report, oversight of cost effectiveness/incremental cost analysis, preparation of permit applications, and presentation with Corps at several public meetings, and development of the ERR and EA.

New Jersey Highway Authority, Driscoll Bridge Estuarine Wetland Restoration, New Jersey.  Responsible for providing tidal wetland mitigation for the NJ Highway Authority’s Bridge Improvements Project over the Raritan River in Middlesex County, New Jersey.  Completed feasibility report analyzing mitigation opportunities and met with federal and state regulatory agencies to select mitigation sites in the densely developed Raritan drainage basin.  Completed restoration design of 7-acre Pine Creek estuarine marsh and obtained regulatory approval and permits.  Managed the sediment and surface water analyses to assess site contamination; hydrodynamic and hydraulic modeling; geotechnical borings, tests and studies; and construction cost estimates.

Trenton Woodbury Wetland Mitigation, New Jersey.  Managed the design, construction, and planting of a 9-acre wetland mitigation site in Freehold, New Jersey. Responsible for construction and planting of the project as a design/build project employing excavation methods to create palustrine and emergent wetland habitat planted with coastal plain woody species.

Augustine North, Stafford County, VA.  Developed final planting plans and specifications for two large irrigation ponds and for a five-acre forested mitigation site in this residential golf course community.  The landscape plans for the irrigation ponds were designed to be an integral aesthetic component of the golf course.


Wetland Mitigation and Permitting for the Development of a Federal Correctional Facility, Glenville, West Virginia.  Designed freshwater wetland mitigation and planting plans for the restoration of a reclaimed mine area located West Virginia.  Responsible for construction of the project as a design/build plan including excavation of soils, re-use of soils adjacent to the wetland mitigation to enhance drainage features, and placement of topsoil.  Coordinated planting activities with Glenville State College, providing hands-on instruction on planting and forestry techniques. 

Wetland Delineation and Permitting for Atholton Park, Howard County, MD.  Identified and delineated the wetlands within a section of the park where site improvements were proposed.  Prepared a Section 404 application for the removal of an in-stream culvert, restoration of the streambed, and installation of a bridge over its wetlands.  Tracked the permit application and received all necessary wetland permits.


Enterprise Shopping Center, Prince George’s County, MD.  Conducted an environmental inventory of the site and used the resulting information to complete an EA and EIS for the project.  Also developed the final mitigation plan to offset wetland losses.  Coordinated with all agencies to secure the necessary permits to allow development of the site.  Provided site supervision of all subcontractors involved in grading and planting the mitigation area. Conducted field work to measure the success of the mitigation and prepared monitoring reports.


Swan Point Wetland Delineation, Baltimore Gas & Electric Company, Issue, MD.  Identified and delineated tidal and non-tidal wetlands using both the 1987 and 1989 delineation manuals.  Performed agency field reviews necessary to receive approval of the delineations.  Conducted habitat studies associated with the wetland permit/certification process.  Prepared permit applications and processed the permits through the U.S. Army Corps of Engineers and state agencies.  Designed and provided full time on-site coordination during the construction of a one-acre tidal wetlands mitigation site.  Conducted field work to measure the success of the created wetlands for three years.  The wetlands received final signoff from all required regulatory agencies.


Route I-287 Wetland Mitigation Studies.  Conducted investigations to identify and select wetland mitigation sites. Analysis included wetland delineation, aquatic sampling and soil borings. Aquatic sampling employed gill nets and ponar grabs. Finfish species were identified in the field while benthic invertebrates were identified to species in the laboratory. Participated in the conceptual wetland design of a site in each of the Ramapo, Passaic and Pequannock River basins totaling more than 90 acres.


Tinkers Creek, Prince George’s County, MD.  Identified and delineated all wetlands within the proposed limits of disturbance for the construction of two regional storm water management facilities.  Coordinated the agency field view of the wetland boundaries and received approval of the boundaries.  Submitted a Section 404 permit application to the U.S. Army Corps of Engineers, and tracked the application to facilitate a timely issuance of the Section 404 and Section 401 certification.  Installed groundwater monitoring wells within the proposed mitigation site to gather data which was used in the development of final design drawing for more than three acres of forested wetlands within the floodplain of Tinkers Creek.  Submitted and received approval of the mitigation plans from the Maryland-National Capital Park & Planning Commission and the Maryland Department of the Environment.


Beehive/Schultz Property, Howard and Anne Arundel Counties, MD Prepared plans for two sites totaling seven acres of emergent wetlands.  Completed post-construction monitoring.


Chesapeake Baptist Church Site, Anne Arundel County, MD.  Prepared plans for six acres of forested and emergent wetlands.
