Shoreland Permitting

Required Information

1. A completed Impervious Surface Area Calculation Worksheet, including a pre-construction site plan and post-construction site plan.  The pre-construction and post-construction site plans can be prepared by a WI-licensed professional surveyor, landscape architect, architect or other party capable of preparing a professionally-drawn to-scale site plan document that matches the size and dimensions of the subject property.

2. Plat of Survey prepared by a hired Wi-licensed professional surveyor showing the following:

• North Arrow.
• Date.
• Scaled drawing of property lines with dimensions.
• Location and dimensions of all buildings and structures located on the property.
• Location of all proposed buildings and structures to be located on the property.
• Ordinary high water mark of any navigable waterway within 100 feet of the property line. 
• Field located 100-year floodplain elevation. 
• All existing and proposed structure footprints (including any cantilevered building floors, decks, patios, sidewalks, retaining walls and other flatwork). 
• Top of foundation elevation for any existing buildings and proposed top of foundation elevation for any proposed buildings or building additions. 
• Location of any septic tank riser located on the property.
• Appx. location of any septic field located on the property. 
• Appx. location of any wetlands located on the property. 
• Any well head located on the property. 

What are shorelands?

State statute defines shorelands as areas within 1,000 feet of a navigable lake or pond and within 300 feet of a navigable river or stream.

Why regulate shorelands?

In their natural state, shorelands provide critical environmental functions, including water filtration, soil stabilization and habitat for a wide variety of fish and wildlife. The Wisconsin Department of Natural Resources estimates that 94% of all aquatic life spends at least part of its life cycle within 30 feet of the shore. 

By replacing natural shore cover with pavement, buildings and turf grass, poorly designed development can impair or disrupt these functions, creating severe environmental impacts. Under Section 59.692 of the Wisconsin Statutes, every county in the state must adopt ordinances that regulate development in shorelands. This protects water quality, natural scenic beauty and fish and wildlife habitats. County ordinances must meet or exceed minimum standards established in NR 115, Wisconsin Administrative Code.

What is a "navigable water?"

Navigable waters are defined in the Public Trust Doctrine and state statute. Generally, they include all natural lakes, ponds, rivers and streams (including intermittent streams). Artificial drainages or stormwater conveyances that were not previously natural waterways are generally not considered navigable. 

Waters shown in USGS Quadrangle maps, Kenosha County floodplain maps, or the Kenosha County Interactive Mapping Application are presumed to be navigable. The Kenosha County Zoning Administrator or the Wisconsin Department of Natural Resources can determine whether or not a particular waterway is navigable under state law.

What is the "ordinary high water mark?"

The ordinary high water mark (OHWM) represents the highest point on the shore where the water can be expected to reach each year, such as in spring floods. 

During late summer or in a drought, the actual water level might be lower than the OHWM. On the other hand, during a flood, the actual water level might be considerably higher than the OHWM. The OHWM serves as the dividing line between Wisconsin DNR regulatory authority and county shoreland zoning. It is also the measurement point for building setbacks and the vegetative buffer zone. 

If you have questions about where the OHWM is located, the County Zoning Administrator or the Wisconsin DNR can set the ordinary high water mark based on field conditions.

Where does the county ordinance apply?

The Kenosha County Shoreland Zoning Ordinance applies only to properties in unincorporated towns. If you are in an incorporated city or village, check with your local zoning agency to determine what regulations apply.

The closer to the water, the more protective the regulations become.

What about wetlands?

Kenosha County ordinance and state and federal law prohibit most construction, ditching or filling within wetland boundaries.  The maps of the Wisconsin Wetland Inventory give a good general idea of the location of wetlands across the state. However, maps are no substitute for field delineation to determine precise wetland boundaries. 

Please note that if you are proposing a project that is located close to a mapped wetland boundary, you will need a wetland delineation and a location survey to make sure wetland setbacks are met.
