Dam Removals and Stream Modification Projects

A High Definition Stream Survey Will Facilitate Your Permit Compliance.

Are you certain that your Nationwide Permit 53 or 27 applications adequately address the potential impact to aquatic life?  If your waterway data is insufficient to support your assumptions, your permitting process could be prolonged and more costly than it needs to be. A High Definition Stream Survey (HDSS) provides a complete assessment of a stream corridor, including detailed data about T&E species and sensitive habitat. Give yourself the benefit of more confident planning and implementation decisions by ensuring you have the data you need to get your project approved.

The HDSS Methodology

The HDSS technique involves the uninterrupted collection of geo-referenced data over long stretches of waterway (click here to learn more about HDSS). The data can be collected on floatable and non-floatable waterways using an array of video equipment and other sensory equipment that convert blue lines on a map to data-rich GIS layers backed up by video documentation. Aquatic habitat can be thoroughly mapped to show sensitive areas that must be considered in the project. HDSS processing will compile the data and produce deliverables tailored to optimize your permitting requirements. 

Don’t limit your data to within a few hundred yards of a project site. While such data may meet technical requirements of a permit, limiting your data can jeopardize the success of your permitting process and the overall goals of the project.
