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.
Construction Wetland Delineation, RBA Group, Statewide,
Pennsylvania. Conducted a wetland investigation of 15 existing
prison properties to be enlarged throughout Pennsylvania to
comply with NEPA regulations. Visited each site and delineated
the limits of wetlands according to the 1987 U.S. Army Corps of
Engineers Manual. Classified all wetlands according to the
Cowardin classification system considering the soils,
vegetation, and hydrology of each site.
Construction/Mitigation Banking Design/Build, Marsh Resources, Inc., NJ. Handled the Phase I design/build
of a 120-acre tidal wetland mitigation bank in the Meadowlands
located in Bergen County, New Jersey. A perimeter dike was
built to prevent water from entering the site, which allowed
excavation of the marsh plain under dry conditions. Site
elevations were lowered from one to five feet, 10,500 feet of
tidal channels were created throughout the site, and
approximately 83,000 cubic yards of material were excavated.
Weekly site visits were made to document project construction
according to plans and specifications.
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.
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 instream culvert,
restoration of the streambed, and installation of a bridge over
its wetlands. Tracked the permit application and received all
necessary wetland permits.
Wetland Delineation Services, Park Authority, Fairfax
County, VA. Under an open-end, task order contract, performed
wetland delineation services. The first task involved
completion of a wetland study for Richard W. Jones Park, a
245-acre site. Three distinct wetland sites were delineated,
and recommendations were made that, if future plans for
development come close to the areas, these areas should be
flagged and surveyed.
Delineation of Freshwater Wetlands, New Jersey Department of
Environmental Protection. Provided field and technical support
on this project to map all of the freshwater wetlands in New
Jersey. Assisted in developing a computerized data entry system
for recording field data for use by State agencies.
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.
Watershed Mitigation Site Selection, Howard County, MD. Participated in the evaluation of over
130 sites in the Patuxent River Watershed, including over 40
sites in Howard County, for their suitability as wetland
mitigation sites. Included an analysis of wetland and upland
vegetation characteristics, soils, depth to water table, percent
slope, hydrologic conditions, and land use characteristics.
Gas & Electric Company, Issue, MD. Identified and delineated
tidal and nontidal 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.
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.
Identification for Richard Jones Park, Fairfax County Park
Authority, Fairfax County, VA. Conducted wetlands
identification and delineation of Richard Jones Park. Prepared
a technical report describing the wetlands and delineation
methodology. Prepared wetland impact assessment and coordinated
results with park planning staff.
System Data Information Storage Building, National Aeronautics and Space Administration, Goddard Space
Flight Center, Greenbelt, MD. Storm water management design and
wetlands evaluation and permitting for a $40 million facility,
housing sophisticated computer areas, workstations, offices,
conference areas, and mechanical/electrical services. Conducted
a wetlands investigation to flag the wetlands boundaries.
Natural Resources Inventory Study, Pennsylvania Department
of Environmental Resource, Scenic Rivers Division. During this
four-month internship, conducted a cultural and natural
resources inventory study of the Pine Creek in Tioga County to
support its inclusion in the Pennsylvania Scenic Rivers
Program. Also met with local groups to explain the Scenic
Rivers Program and to foster support for the inclusion of the
Station New Orleans, U.S. Coast Guard. Completed a wetland investigation of the
project site in accordance with the U.S. Army Corps of Engineers
(USACE), Wetland Delineation Manual. Applied for and lead a
jurisdictional Determination field meeting with the USACE to
confirm the limit of jurisdictional wetlands. Reviewed the
USACE project files related to the history of Section 404/401
permitting on this parcel. Met with USACE regulators to discuss
this proposed project and to garner their support for the
Integrated Support Command,
U.S. Coast Guard, Portsmouth, VA. Completed a wetland
investigation of the project site in accordance with the Corps
of Engineers Wetland Delineation Manual. This investigation
determined that no wetlands were present within the project
site. Reviewed the requirements of the Chesapeake Bay
Preservation Act to determine what classification the project
falls within, and therefore what reductions in non-point source
pollution would be required.
Montgomery County, MD. Completed wetland delineations, impact
assessments, agency coordination, and Section 404 and 401
permitting. Through negotiations with the resource agencies,
arranged to have the wetland mitigation requirements converted
from creation to riparian buffer establishment, which resulted
in considerable cost savings to the client. Contributed to the
development of the Lake Helene storm water management retrofit
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
