Wetland Determination & Delineation

Cardno understands how the presence of wetlands can influence land-use decisions. Our Professional Wetland Scientists are trained to undertake two levels of wetlands identification.

To obtain cost effective preliminary information early in a project, clients request a wetland determination where we:

  • evaluate available maps of the property to initially determine if wetlands may be present
  • inspect the site to verify whether regulated wetlands are present
  • establish their general extent and location.

With this information Cardno then helps clients determine how the wetlands may affect their project and what state or federal permits may be required. Clients often use this information in early "go or no go" decisions.

A wetland delineation is a more detailed process that specifically defines the legal boundary of jurisdictional wetlands on a property. This boundary separates the regulated wetland from the upland areas on site. It is critical to identify the exact wetland boundary and acreage for permitting of impacts to wetlands or other regulated waters. It is often prudent to have a wetland delineation carried out to provide documentation that you have avoided impacts to wetlands.

To provide increased accuracy and efficiency on even the most complex delineation projects, Cardno uses GIS/GPS to integrate this data into geo-spatial decision-making tools. 

Cardno has completed thousands of delineations throughout the Midwest, from less than one acre to several thousand acres, and from small bridge crossings to almost two thousand mile-long linear corridors. 

These services form the scientific basis for our permit applications, whether for Clean Water Act Sections 401 or 404, or for state wetland permitting requirements.
