Wetland Protection

Wetlands are critical biological resources that provide important wildlife habitat and play a key role in flood prevention, surface water management, groundwater recharge and water quality. Wetlands include land areas usually saturated with water and have vegetation which is specific to wetland soils. These areas include all streams and other bodies of water and frequently include areas adjacent to bodies of water. Both the federal and state governments have wetland protection laws in place. Municipalities can also directly protect and more effectively regulate disturbances of wetlands.

In addition to federal and state regulation, local municipalities can take additional steps to protect wetlands from the impacts of development and from unnecessary disturbance. Wetland protection regulations are applicable to all landscapes and any municipality with wetland areas should consider developing wetland management standards. Land management and zoning tools such as "netting out" wetlands from lot area and density calculations, regulating the disturbance of wetlands and protecting wetland margins can be incorporated into local zoning and subdivision and land development ordinances.

How to Use this Tool

The protection of the natural environment, including wetlands, should serve as the primary basis for other land use policies and can result in the conservation of critical resources for future generations. Preserving, improving and managing water quantity are key components of protecting the natural environment.

Protection of wetlands through methods such as regulatory controls, open space and greenway preservation and management, and stormwater best management practices can conserve resources, protect natural functions, and improve quality of life. Locating a full range of natural resource protection standards in one section of a municipal ordinance allows for the most effective protection of those resources at the local level. Ordinances should require that the specific natural features first be identified on a proposed plan and then apply limitations on their disturbance. A comprehensive list of protected resources should include, at a minimum: wetlands, woodlands, steep slopes, riparian buffers, and floodplains.

Municipalities that are developing or updating their wetland protection standards should consider the following:

Examples

The majority of Chester County municipalities have incorporated some level of wetland protection into their ordinances. Chester County municipalities also manage and regulate floodplain areas.
