Wetlands & Streams

What is a Wetland?

Wetland areas are protected by both the federal and the state government in accordance with the Clean Water Act of 1970 and subsequent regulations.

Delineation Services

Tinkers Creek Watershed Wetland Assessment

Tinkers Creek Watershed Wetland Assessment

EnviroScience’s wetland scientists perform wetland delineations on properties ranging in size from one to 6,000+ acres and in appearance from nearly pristine to severely-disturbed landscapes.

Our environmental experts are fully trained in the current methods of wetland delineation in accordance with the U.S. Army Corps of Engineers (USACE) Delineation Manual and Regional Supplements. Additionally, they are well-versed in performing survey techniques using a state-of-the-art Trimble® differential GPS.

GPS data collection allows EnviroScience to prepare wetland maps without the need and additional cost of traditional survey teams. The survey map and flagging of wetland boundaries provide a strong planning tool for any project involving changes in land use.

Delineation reports are completed to suit the client’s project-specific needs while complying with state and federal reporting requirements. Wetland maps are prepared using AutoCAD® or ArcGIS® software and are available in digital format to ensure compatibility with construction drawings.

Wetland Permit Applications & Water Quality Certification Applications


Wetlands & Streams

Projects requiring unavoidable impacts to wetlands require USACE and/or Environmental Protection Agency (EPA) approval. EnviroScience prepares and submits application packages for clients applying for Section 404 permits, Section 401 Water Quality Certifications, and Isolated Wetland Permits. Our biologists have an excellent reputation with regulatory agencies based on our decades of quality work, and this reputation helps our clients obtain approvals in a timely manner.

Wetland Mitigation and Restoration

Mitigation for wetland impacts and stream habitat losses is frequently a necessary part of project planning given today’s rules governing impacts to wetlands and other aquatic resources. EnviroScience wetlands scientists consult with clients to identify strategies to avoid and/or minimize construction impacts to wetlands and streams.

When impacts are unavoidable, we develop project-specific mitigation plans which may include mitigation banking, in-lieu fee arrangements, and wetland creation. When wetland creation is the preferred mitigation choice, EnviroScience can complete turnkey wetland creation services including analyzing of wetland functions and values, site selection, water budget, design, construction, and plantings.

EnviroScience biologists remain involved after wetland creation to ensure successful completion through regular ecological monitoring, follow-up plantings, invasive species control, and submission of required reports to USACE. Our design-build approach allows our biologists to be involved in projects from start to finish ensuring that the completed project meets the client’s needs.

Available Habitat is a Key Limiting Factor for Species Diversity



Assessment of stream habitat is an important step in biomonitoring and restoration projects. Almost every project has a habitat evaluation component because it can be a critical limiting factor for species diversity, therefore cost and effort can be minimized by first assessing habitat.

EnviroScience has decades of experience evaluating in-stream and riparian habitat. Our scientists can evaluate stream habitat from small headwater streams to major river systems like the Allegheny and Ohio rivers.

Oftentimes, habitat can vary greatly—even within a few feet. Therefore, EnviroScience incorporates the latest technology, such as underwater video and GIS/GPS mapping, in conjunction with standard evaluation forms such as the Qualitative Habitat Evaluation Index (QHEI) to provide a visual and descriptive analysis of project area habitat.

Our biologists can assess stream habitat using a range of innovative methods, including:


EnviroScience offers a range of restoration services for a wide variety of clients. Restoring streams and wetlands is a rapidly growing discipline that supports water quality, mitigation, stormwater and watershed management issues. Our biologists design natural functional restoration projects to address water quality issues, habitat enhancement, mitigation and permit requirements.
