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 manage runoff so that a majority of precipitation events are absorbed. Infiltration devices, such as gravel filled trenches, drywells, and ground surface depressions, facilitate this process by putting runoff in direct contact with the soil and holding the runoff 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. Infiltration Devices The infiltration devices used on your property include the following as indicated on 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 development permit from the City of Renton. 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 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. 5 of 6 TYPICAL FULL INFILTRATION APPLICATIONS 6" 24" 12" 24" WASHED ROCK 1 12"- 34" LEVEL INFILTRATION TRENCH SECTION ANTS PLAN VIEWNTS SECTION VIEW NTS VARIES A A 6" 6" 4" RIGID OR 6"FLEXIBLEPERFORATEDPIPE CB SUMP w/SOLID LID ROOF DRAIN 4" RIGID OR 6" FLEXIBLEPERFORATED PIPE OVERFLOW SPLASH BLOCK ROOF DRAIN CB SUMP w/SOLID LID 12" FINE MESHSCREEN SETBACKFROMBUILDING5' MIN. 1' MIN.1' MIN.
