Full infiltration is a method of soaking runoff from impervious area(such as paved areas and roofs) intv the ground. If properly installed and maintained per Appendix A of the City of Rentvn's Surface Water Design Manual,full jnf ltrat�on can manage runoff so t}�at a majority of�reci�itat�on events are absorbed. Infiltration devices, such as gravel filled trenches,drywells, and ground surface depressions, facilitate this process by pi�tting n�noff in direct contact with the soil and holding the n�noff long enou�h to soak most of it into the�round.To be successful,the soil condition around the infiltration device must be reliably able to soak water i�to the grour�d far a reasonable number of years. Infiltration Devices The infiltration devices used�n your pr�perty include the f�llowing as indicated�n the site plan(CHECK THE BOX(ES) THAT APPLY): �gravel filled trenches, ❑drywells, ❑ground surface depressions. MAINTENANCE RESTRICTIONS The size,placement, and composition of these devices as depicted by the site plan and design details must be maintained and may not be changed without written approval from the City of Renton or through a future developn�er�t pernut from the City of Rerrtor�. INSPECTION FREQUENCY AND MAINTENANCE GUIDELINES � Infiltration devices must be inspected annually and after major storm events to identify and repair any physical defects. � Maintenance and operation of the system should focus on ensuring the system's viability by preventing sediment-laden flows from entering fhe device. Excessive sedimentation will result in a plugged or non-functioning facility. • If the infiltration device has a catch basin, sediment accumulation must be removed on a yearly basis or more frequently if necessary. • Prolonged ponding around or atop a device may indicate a plugged facility. If the device becomes plugged, it must be replaced. • Keeping the areas that drain to infiltration devices well swept and clean will enhance the longevity of these devices. � For roofs,frequent cleaning of gutters will reduce sediment loads to these devices.

Permeal�le pavements reduce the amount of rain�'all that l�ecomes runoff l�_y allowing water to seep through the pavement into a free-draining gravel or sand bed,where it can be infiltrated into the ground. 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 �SI Porous asphalt ❑ Permeable pavers ❑ Modula:r grid pavement MAINTENANCE RESTRICTIONS The area covered by permeable pavement as depicted by the site plan and desi�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 permit from the City of Renton. INSPECTION FREQUENCY AND MAINTENANCE GUIDELINES • Permeable pavements must be inspected after�ne maj�r st�rm each year t�make sure it is working properly. Mare frequent inspection is recommended. • Prolonged ponding ar standing water on the pavement surface is a sign that the system is defective and may need to be re�laced. If this occurs, contact the�avement installer ar 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 res�onsible far the re�iair of all ruta,deformation, and/ar broken�aving grids ar pavers. • Modular grid pavement and permeable pavers filled with gravel or with gravel in the joints may need to be refilled periodically.
