The dispersion devices used on your property include the following as indicated on the flow control
BMP site Plan splash blocks. 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 fro1m 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 and/or 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.
