Full infiltration is a method of soaking runoff from impervious area(such as paved areas and roofs) into the ground. If properly installed and maintained per Appendix A of the City of Renton's Surface Water Design Manual, full infiltration can inanage runoff so that a inajority of precipitation events are absorbed. Infiltration devices, such as gravel filled trenches, drywells, and ground surface depressions, facilitate this process by putting runotf in direct contact with the soil and holding the runotf long enough to soak most of it into the ground. To be successful,the soil condition around the infiltration device must be reliably able to soak water into the ground for a reasonable number of years. lnfiltration Devices The infltration devices used on your property include the following as indicated on the site plan(CHECK THE BOX(ES)THAT APPLY): ❑gravel filled trenches, l�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 development permit from the City of Renton. INSPECTION FREQUENCY AND MAINTENANCE GUIDELINES • Infiltration devices must be inspected annually and after maj or 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 the 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.

Basic dispersion is a strategy for utilizing any available capacity of onsite vegetated areas to retain, absorb, and filter the runoff from developed surfaces. This on-site BMP has two primary components that must be maintained: (1)The devices that disperse runoff from the developed surfaces and (2)The vegetated area over which runoff is dispersed. Dispersion Devices The dispersion devices used on your property include the following as indicated on the site plan(CHECK THE BOX(ES)THAT APPLY): � splash blocks, ❑ rock pads, ❑ gravel filled trenches, ❑ sheet flow. MAINTENANCE RESTRICTIONS The size,placement, composition, and downstream flowpaths 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 development permit from the City of Renton. INSPECTION FREQUENCY AND MAINTENANCE GUIDELINES This on-site BMP has two primary components that must be maintained per Appendix A of the City of Renton's Surface Water Design Manual: (1)The devices that disperse runoff from the developed surfaces and (2)The vegetated flowpath area over which runoff is dispersed. Maintenance of Dispersion Devices • Dispersion devices must be inspected annually and after maj or storm events to identify and repair any physical defects. • When native soil is exposed or erosion channels are present,the sources of the erosion or concentrated flow need to be identified and mitigated. • Concentrated flow can be mitigated by leveling the edge of the pervious area and/or realigning or replenishing the rocks in the dispersion device, such as in rock pads and gravel filled trenches. Maintenance of Vegetated Flowpaths • The vegetated area over which runoff is dispersed must be maintained in good condition free of bare spots and obstructions that would concentrate flows.
