Permeable Pavement. To ensure the proper long-term function of the permeable pavement system, the following activities must be completed by the owner. Operation and Maintenance shall conform to Section VIII of WI DNR Technical Standard 1004.
Permeable Pavement. Pervious pavement costs approximately $3,960 per acre of tributary area per year. The site contains approximately 0.34 acres of area flowing to permeable pavement. This equates to an approximate cost of $1,350 per year to maintain the permeable pavement. Based on the costs outlined above, the stormwater system will cost approximately $1,350 per year to maintain. This is only an estimate and costs may vary. These costs are the responsibility of the stormwater system owner. Funding for the costs will be provided by the owner.

Permeable Pavement. System that provides a hard surface, while allowing water to flow through to the underlying soils instead of into the storm sewer. It is a low impact development technique in which the space used for the practice can also be used for sidewalks, roads, and parking spaces.
Permeable Pavement. What is Permeable Pavement? Permeable pavement (also known as pervious and porous pavement) looks very much like ordinary pavement except it has small openings that allow water to pass through and eventually soak into the ground. Permeable paving significantly reduces the amount of stormwater runoff compared to conventional pavement. How does Permeable Pavement Work? After water drains through permeable pavement, it is held in a storage reservoir bed (made up of aggregate rock, or drain rock), and then slowly soaks (infiltrates) into the ground. There are four main types of permeable pavement. • Porous asphalt • Pervious cement concrete • Interlocking concrete paver blocks • Open-celled paving grid systems How do I maintain my Permeable Pavement? Permeable pavements are engineered systems, and some larger or more complex designs may require the assistance of professional experts to perform maintenance inspections and activities. The following are required maintenance practices for Permeable Paving. Note that not all design elements will be present in all permeable pavement applications: Do General • Check adjacent areas to ensure that they are not depositing soil, mulch, or sediment on the permeable pavement area. Replant or stabilize adjacent pervious areas to reduce erosion if needed. • Check for fallen leaves or debris and remove if present. • Check for sediment or debris accumulation between paver blocks, on surface of pavement, or in grid voids and remove if present. Inlet, outlet, and underdrain pipes (if present) • Check inlet and outlet pipes for clogging or damage. Repair, replace, and remove debris as needed. • Check areas around inlet and outlet pipes for erosion (exposed soil), and eliminate cause of erosion if present. • Check underdrain pipe for plant roots, sediment, or debris. Jet clean, cut roots, and remove debris of present. • Check and clean orifice (if present). Porous asphalt and pervious cement concrete • Check adjacent vegetation to ensure it is not growing into the permeable pavement area. Trim or remove vegetation that encroaches upon the permeable pavement area. • Perform regular maintenance to prevent clogging with fine sediments. Use a vacuum or power washer with rotating brushes two to three times annually. • Protect permeable pavement area from any adjacent construction site runoff during project construction. • Check for cracks or trip hazards in the pavement area. For potholes or small cracks, fill with patching mixes. For ...
Permeable Pavement. Permeable pavement costs approximately $3,960 per acre of tributary area per year. The site contains approximately 2.08 acres of area flowing to permeable pavement. This equates to an approximate cost of $8,236.80 per year to maintain the permeable pavement Based on the costs outlined above, the stormwater system will cost approximately $8,236.80 per year to maintain. This is only an estimate and costs may vary. These costs are the responsibility of the stormwater system owner. Funding for the costs will be provided by the Owners Association.
