Wetland Services

EA’s wetland ecologists have provided wetland delineation, study, creation, restoration, and management services across all 50 States and five territories.

Capabilities

Working in close partnership with federal, state, and local agencies, EA has formulated proactive management approaches that avoid potential conflicts between land and water use activities and natural resources. One of the primary objectives of our recommended solutions is to integrate both land use and ecological integrity simultaneously rather than simply mitigating conflicts.

EA’s wetland experience ranges from the sea grass meadows in the U.S. Virgin Islands, to the depressional marshes on Attu Island, Alaska, to the hardwood forested swamps of New England, and over to the mangrove forests of Guam and American Samoa.

Capital Region Parks

EA developed a comprehensive approach to identify wetlands, waterways, and riparian habitats for restoration, enhancement, and protection. Desktop analyses were followed by field reviews and wetland delineations where appropriate. Conceptual design plans were developed for stream and wetland restoration opportunities at all sites.

EA was contracted by the Nebraska Department of Transportation (NDOT) to provide wetland delineation, mitigation, monitoring, and permitting services in support of transportation projects. EA provided NDOT qualified wetland scientists with expertise in Midwest/Great Plains wetlands, USACE Section 404 permitting, and related regulatory compliance. EA services included wetland and Waters of the U.S. delineations, jurisdictional determinations, mitigation monitoring, completion of standard reports, creation of geographic information system geodatabases, and coordination with federal and state agencies for multiple task orders for sites throughout Nebraska.
