Sewer Service Area Planning & Stormwater and Erosion Controls

Stormwater Management

The management and regulation of stormwater is divided among federal, state, county and local governments, depending on the land's status of incorporation and size and the activities affecting stormwater on the land.

The thorough nature of comprehensive stormwater planning implies long-range and geographically broad consideration of flows and water quality during and after development of major land parcels, such as highways, industrial parks and residential neighborhoods. With few exceptions, maintenance of pre-development hydraulics is most desirable. The large-scale nature of comprehensive planning allows the integration of resources to reach multiple regulatory and management goals, such as those of FEMA, NR 216, sewer service area planning, local water management regulations and even management for aquatic and terrestrial wildlife.

Municipal Stormwater

Wisconsin has been authorized to administer the NPDES program and has promulgated regulations at the state level.   For more information, see Municipal Storm Water Management.

To address flooding and control water quantity, the Federal Emergency Management Authority (FEMA) requires municipalities to perform floodplain mapping and management plan development to receive federal flood insurance.   For more information, see Wisconsin's Floodplain Management Program.

Industrial Stormwater

Under NR216, discharges of stormwater from certain facilities require coverage under an industrial stormwater discharge permit. The owner or operator of the permitted industrial facility is required to develop and implement a site-specific stormwater pollution prevention plan. The plan must be designed to ensure that there are practices in place to reduce exposure of industrial materials to stormwater, such as good housekeeping, spill prevention and cleanup and structural and non-structural controls.  For more information, see Industrial Storm Water Management.

Construction Site Erosion Control

As land is developed and disturbed, sediment moving off-site can be significant unless proper erosion control measures are implemented. For more information, see Construction Site Erosion Control & Storm Water Management.
