MAINTENANCE INSTRUCTIONS FOR FULL INFILTRATION
Your property contains a stormwater management flow control BMP(best management practice)called
full infiltration,"which was installed to mitigate the stormwater quantity and quality impacts of some or
all of the impervious surfaces on your property.
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.

MAINTENANCE INSTRUCTIONS FOR FULL INFILTRATION
Your property contains a stormwater management flow control BMP(best management practice)called
full infiltration,"which was installed to mitigate the stormwater quantity and quality impacts of some or
all of the impervious surfaces on your property.
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):
6ef 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 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.
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.
