Wetland delineation completed in Thornton, Colorado. Received concurring approved jurisdictional determination from the United States Army Corp of Engineers.

Roe Ecological Services has the qualifications to perform a wetland delineation on your property to determine if a wetland exists. ROE will then work with the appropriate federal agencies to determine if the wetland is jurisdictional (i.e., requires a permit to impact). If a wetland exists, and it is determined to be jurisdictional, we can provide permit assistance and/or identification of mitigation or avoidance options.

The Clean Water Act of 1972 (33 U.S.C. § 1251 et seq.) regulates quality standards for surface waters in the United States. Generally, under Section 404 of the Clean Water Act, placing any fill material into “waters of the United States” requires a permit (known as a “404 permit”) from the Corp of Engineers. “Waters of the United States” include wetlands if the degradation or destruction thereof “could affect” interstate commerce. Section 404 also requires a permit for land leveling, dam construction, dredging/ditching activity where the excavated materials are cast to the side, and other activities that might adversely impact the integrity and functionality of any biological system.

The previous consultant on this particular project incorrectly identified approximately 3-4 acres of what it claimed were “jurisdictional” wetlands on this property, which could have cost the client potentially $400,000+ for mitigation and additional consulting fees. RES reassessed the property and determined that the wetlands existed on a much smaller scale, and ascertained that the areas, even if they could be classified as wetlands under the Corp of Engineers definition, were not jurisdictional. The Corp of Engineers agreed, saving this client hundreds of thousands of dollars.
