Keep the Town of Cedarburg safe by preventing stormwater pollution and illicit discharges. An illicit discharge is a substance other than stormwater that is released to a storm drain, storm sewer, or other drainage system that directs to a lake or river. These substances are considered “illicit”, or banned, because they are hazardous to our water resources. Examples of illicit discharges can include sanitary waste water, effluent from septic tanks, lawn fertilizers, vehicle fluids, paints, concrete, and other hazardous wastes. You can learn more about illicit discharges, how to identify and prevent them, and how to properly dispose of hazardous wastes at:

Septic Replacement / Rehabilitation Grants
The Wisconsin Fund Program provides grants to homeowners and owners of small businesses that need to replace a failing private onsite wastewater treatment system with a new system. A farm of 35 acres or more may also be considered a small business. Click here to find out more about this program, including eligibility and the application process.
MS4 ANNUAL REPORT
The Town submits an annual MS4 permit to meet reporting requirements on activities undertaken pursuant to the Municipal Separate Storm Sewer System general permit. The report is due to the WDNR by March 31st of each year to report on activities of the previous year.
In 2006, the Town of Cedarburg received a Non-point Pollution Discharge Elimination System (NPDES) permit from the Wisconsin Department of Transportation. This is a fancy term for a permit to reduce pollution, mainly the amount of dirt, sand, and other debris, called total suspended solids, that is collected in rain water run-off and eventually gets to Cedar Creek or the Milwaukee River. Most of the communities along Cedar Creek and the Milwaukee River are under similar permits. As part of the permit, the Town developed a stormwater quality management plan, which outlines requirements for the Town, private development, and even individual land owners to control the pollutants in run-off.
There are three components to the storm water quality management plan. The first is a post-construction storm water management plan. This plan is generally required when a development or improvement will have a large area of impervious, or non-absorbing, surfaces such as building roofs or paved parking lots after construction. If a development will result in more than 10% of the site being impervious a management plan is required (see technical standards). This plan is designed to reduce the amount of rain run-off from site that equals the amount of run-off if the site was completely left undeveloped.
The most common way to reduce this run-off is to create a pond that will hold rain run-off and release it to ditches or streams at slow rate. Holding the water for a time allows the total suspended solids to settle out and let clean water into the ditches, streams, wetlands, and lakes. Another method to control run-off is to construct a rain garden. These gardens are small shallow ponds planted with native Wisconsin plants. The gardens will collect water from downspouts, sump pumps, or parking lots, hold the water and let it seep into the ground. This method purifies the run-off through filtration and can help regenerate groundwater. The Town has constructed demonstration rain gardens at Town Hall and at the Fire Station on Covered Bridge Road. A third method for controlling storm water is through the use of rain barrels. These barrels are placed at the discharge point of a downspout to collect the run-off from the roof. The solids settle out and the water is recycled, used to water lawns, and gardens. Rain barrels may be ordered through Ozaukee County.
The second component to the storm water management plan is to control sediment that runs off from construction sites. To accomplish this almost all construction requires an erosion control permit. This permit defines the methods that will be used to control erosion from a construction site and lists a plan to maintain the controls (technical standards). Anyone doing work on their property that involves grading or moving ground, should contact Town Hall to check if an erosion control permit is required.
The third requirement of storm water management is to reduce and ultimately eliminate toxic or environmentally harmful elements, known as illicit discharges, from getting into the lakes, wetlands, and streams. Examples of illicit discharges are chemical spills, gasoline, oil, and antifreeze, soap and detergent, and liquid food wastes, such as milk and cooking oil. Town staff does periodic surveys of key discharge points near wetlands, streams, and lakes to check for these discharges. If they are found, the Town will try to determine where the illicit discharge came from and will levy fines and possibly press criminal charges on those responsible. This is one area where you can assist the Town. If you notice water in your ditch looks milky, has a rainbow-like sheen on the surface, or there is a strong odor from the ditch, please contact Town Hall at (262) 377-4509.
The illicit discharge ordinance also requires new or replaced sump pump and roof drain outlets to be at least ten feet from a property line. Ditches and drainage ways generally follow property lines and keeping the discharge point back from these drainage ways allows for some removal of suspended solids and prevents erosion of and sediment build-up in the ditches.
There are a number of services provided by the Town that deal with storm water management. The first of these services is maintenance of the ditches along Town roads and public drainage easements. The Public Works department re-grades or cleans out thousands of feet of ditches to improve the flow in the ditch, and to reduce a flooding potential to properties along the ditches.
Stormwater management also involves maintenance of the culverts. There are three types of culverts. Cross-culverts convey water from a ditch on one side of a road to a ditch, wetland, lake or stream on the other side of the road. These culverts are maintained by the Town and are replaced if they are damaged, undersized, or no longer functioning properly. If you think a cross culvert in your neighborhood might need replacing, please call Town Hall at (262) 377-4509.
The second type of culvert is the driveway culvert. These culverts are placed in the ditch, under a driveway. These culverts are the responsibility of the property owner to maintain and replace if they are no longer functioning. Installation of a new culvert, lengthening, or replacement of an existing culvert requires a permit from the Town. The cost for this permit can be found on the Town fee schedule, and the application can be accessed by clicking here. The Town Engineer will survey the site, determine the need for a culvert, what size is needed, and set grades for the culvert. After the culvert is installed the Engineer will verify the grades and, if the culvert is correctly installed, approve the installation. For new home construction, this process must be completed before the Town will release the Building Permit. When a Town road is scheduled to be reconstructed or repaved, the Town Engineer will survey all the driveway culverts along that road. If a driveway culvert is undersized, deteriorated or not functioning properly, the Town will replace that culvert prior to the roadwork. Replacement of the culvert may require re-grading of the ditch, which is also done by the Town. All this work, along with most paving and restoration, is done at no cost to the property owner.
The third type of culvert is a temporary culvert. If a property owner needs temporary access to another part of his/her property, he/she may obtain a temporary culvert permit. This permit allows the owner to place a minimum 12 inch culvert in the flow line of a ditch, and place gravel over it to create a temporary access to the property. Once the owner no longer needs the access, the gravel and culvert are removed and the owner must restore the ditch to its original condition. There are two options for the temporary culvert. The first option is for the property owner to do all the work and only pay a culvert permit fee of $125. The second option is for the Town to install and remove the culvert and gravel for a permit fee of $350. If the temporary culvert is installed without a permit, the property owner could be subject to a fine equal to twice the permit fee.
