Wetlands Regulations: Considerations for Project Developers

Posted on 12-18-2018

By: Mark A. Chertok and Elizabeth Knauer

This article discusses considerations for developers contemplating the purchase or development of real property that contains or is likely to contain regulated wetlands. The presence of regulated wetlands on a site proposed for development can often present complications in terms of time and expense in securing permits as well as restrictions on the type or magnitude of development that regulators will approve. In some circumstances, permits may be denied altogether. Wetlands can be regulated at the federal, state, and municipal levels. This article focuses on the federal regulatory regime.

Why Regulate Wetlands?

Substantial declines in wetland acreage in the United States have been documented over the past 50 years, as the result of filling for agriculture and other development. 1 Beginning in the 1970s, recognition arose that wetlands—both freshwater and tidal—perform essential functions in preventing flooding through the retention and slow release of excess water. Wetlands purify storm water runoff by filtering out nutrients, sediments, and pollutants, thereby protecting both surface and ground water. They also provide nesting, wintering, resting, and feeding grounds for numerous species of migratory waterfowl. Estuaries provide critical food sources, spawning grounds, and nurseries for coastal fish and shellfish on both coasts. 2 Therefore, they have become the subject of regulatory efforts to protect them, primarily through permitting standards that are designed to require developers to avoid or minimize incursions on wetlands, and to mitigate any loss of wetlands through replacement or restoration projects.

Extent of Federal Jurisdiction over Wetlands

Waters of the United States

The primary basis for the federal regulation of wetlands derives from Section 404 of the Federal Water Pollution Control Act (Section 404), commonly known as the Clean Water Act (CWA). 3 CWA Section 404 grants the U.S. Army Corps of Engineers (Corps) the authority to issue permits for discharges of dredged or fill material into “navigable waters,” which the Act defines as “waters of the United States.” 4 This term includes not only traditional navigable waters but also tributaries thereto, interstate waters and wetlands, and wetlands adjacent to any of these waters. 5 (Traditionally navigable waters are those that “are currently used, were used in the past, or may be susceptible to use in interstate or foreign commerce, including all waters which are subject to the ebb and flow of the tide.” 6 )

Elizabeth Knauer is a principal of Sive, Paget & Riesel P.C. Elizabeth’s practice includes a variety of permitting, environmental review, and enforcement matters as well as environmental litigation. She advises clients and negotiates with agencies with respect to environmental impact assessment and litigation under the State Environmental Quality Review Act and the National Environmental Policy Act, permitting under the Clean Water Act and Rivers and Harbors Act and state counterparts for work in wetlands and surface waters, and environmental remediation. She frequently defends land use and other determinations made by municipal and state agencies when legal challenges are filed on environmental grounds. Elizabeth’s broad litigation experience also includes matters relating to environmental permitting standards, wetlands jurisdiction, environmental contamination, administrative law, and contractual provisions related to environmental conditions.
