PiPes. f MAINTENANCE INSTRUCTIONS FOR PERMEABLE PAVEMENT �NON-VEGETATED) Your properiy contains an on-site BMP(best management practice)called"permeable pavement," which was installed to minimize the stormwater quantity and quality impacts of some or all of the paved surfaces on your property. Permeable pavements reduce the amount of rainfall that becomes runoff by allowing water to seep through the pavement into a free-draining gravel or sand bed,where it can be infiltrated into the gound. This on-site BMP shall be maintained per Appendix A of the City of Renton's Surface Water Design Manual. Permeable Pavements The type(s)of permeable pavement used on your property is(CHECK THE BOX(ES)THAT APPLY): �Porous concrete ❑Porous asphalt ❑Permeable pavers ❑Modular grid pavement MAINTENANCE RESTRICTIONS The area covered by permeable pavement as depicted by the site plan and design details must be maintained as permeable pavement and may not be changed without written approval from the City of Renton or through a future development pernut from the City of Renton. INSPECTION FREQUENCY AND MAINTENANCE GUIDELINES • Permeable pavements must be inspected after one major storm each year to make sure it is working properly.More frequent inspection is recommended. • Prolonged ponding or standing water on the pavement surface is a sign that the system is defective and may need to be replaced.If this occurs,contact the pavement installer or the City of Renton for further instructions. • A typical permeable pavement system has a life expectancy of approximately 25 years.To help extend the useful life of the system,the surface of the permeable pavement should be kept clean,stable and free of leaves,debris,and sediment through regular sweeping or vacuum sweeping.Aggregate fill in modular grid pavement may need periodic surface replenishment. • The owner is responsible for the repair of all ruts,deformation,and/or broken paving grids or pavers. • Modular grid pavement and permeable pavers filled with gravel or with gravel in the joints may need to be refilled periodically.
