C.2A BASIC DISPERSION
C.2.4.6 MAINTENANCE INSTRUCTIONS FOR BASIC DISPERSION
If the basic dispersion flow control BMP is proposed for a project, the following maintenance and
operation instructions must be recorded as an attachment to the required declaration of covenant and
grant ofeasement per Requirement 3 of Section C. 1..3.4 (p. C-23), The intent of these instructions is to
explain to future property owners, the put -pose of the BMP and how it must be maintained and operated.
These instructions are intended to be a minimum; DLS-Permitting, may require additional instructions
based on site-specific conditions,. Also, as the County gains more experience with the maintenance and
operation of these BMPs, future updates to the instructions will be posted on King County's Sitiface Water
DesignMarmal website.
A reproducible copy of the instructions, prepared for inclusion with the declaration of coveriant, is located
in Reference M.
Your property contains a stormwater management flow control BMP (best management practice) called
"basic dispersion," which was installed to mitigate the stormwater quantity and quality impacts of some or
all of the impervious surfaces or non-native pervious surfaces on your property. 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 flow control 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 flow control BMP
site plan: U splash blocks, Q rock pads,A gravel filled trenches, is sheet flow. The size, placement,
composition, and downstream flowpaths 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.
Dispersion devices must be inspected annually and after major 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 andfor realigning or replenishing the rocks in the dispersion device, such as
in rock pads and gravel filled trenches.
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.
