Wetland Mitigation Site Selection and Assessment

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.

Open-End Contract for H&H Studies and Wetland Delineation, Maryland State Highway Administration, Bureau of Highway Design.  Delineated, flagged, and mapped wetlands within rights-of-way for highway projects statewide.  Coordinated with the U.S. Army Corps of Engineers for the review and permitting of these projects.  Also identified potential wetland impact mitigation sites within rights-of-way.

US 421 Corridor Study, North Carolina Department of Transportation, Wilkes and Yadkin Counties, NC.  Authored sections of an EA for seven miles and an EIS for 10 miles of limited-access highway to be upgraded from two lanes to four.  Identified, flagged, and mapped impacted wetlands.

MD 32 Wetlands Mitigation, Howard County, MD.  Identified and delineated, including flagging, all wetlands within the proposed right-of-way.  Prepared a report describing the wetland systems.  Identified all potential mitigation sites within the study area and adjacent properties.  Prepared avoidance/minimization/mitigation report to facilitate the permit process.  Designed final engineering plans and specifications for two acres of forested wetland mitigation adjacent to Cricket Creek near the MD 32 crossing.

US 70 EIS, North Carolina Department of Transportation, Wake and Johnston Counties, NC.  Searched for potential wetland mitigation sites and prepared conceptual mitigation site.

Patuxent River 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.

Public Service Electric & Gas Company (PSE&G), Salem, New Jersey.  Managed wetland mitigation and cultural services associated with the PSE&G Estuary Enhancement Program. The focal point of this estuary enhancement program was the restoration of more than 10,000 acres of saltmarsh in New Jersey and Delaware.
 

Statewide 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.

Kentlands, 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 plan.
