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,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 flow control BMP site plan(CHECK THE BOX(ES)THAT APPLY): la/gravel filled trenches,drywells,ground surface depressions. MAINTENANCE RESTRICTIONS The size,placement,and composition of these devices as depicted by the flow control BMP site plan and design details must be maintained and may not be changed without written approval either from the King County Water and Land Resources Division or through a future development permit from King County. INSPECTION FREQUENCY AND MAINTENANCE GUIDELINES 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 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 niay 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. RECORDING REQUIREMENT These full infiltration flow control BMP maintenance and operation instructions must be recorded as an attachment to the required declaration of covenant and grant of easement per Requirement 3 of Section C.1.3.4 of the King County Surface Water Design Manual. The intent of these instructions is to explain to future property owners,the purpose of the BMP and how it must be maintained and operated. These instructions are intended to be a minimum;the King County Department of Permitting and Environmental Services(DPER)may require additional instructions based on site-specific conditions. See King County's Surface Water Design Manual website for additional information and updates.
