EXHIBIT B
MAINTENANCE INSTRUCTION FOR PERFORATED PIPE CONNECTION
Your property contains a stormwater management flow control BMP (best management
practice) called a "perforated pipe connection," which was installed to reduce the
stormwater runoff impacts of some or all of the impervious surface on your property. A
perforated pipe connection is a length of drainage conveyance pipe with holes in the
bottom, designed to "leak" runoff, conveyed by the pipe, into a gravel filled trench
where it can be soaked into the surrounding soil. The connection is intended to provide
opportunity for infiltration of any runoff that is being conveyed from an impervious
surface (usually a roof) to a local drainage system such as a ditch or roadway pipe
system.
The size and composition of the perforated pipe connection 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 City of Renton or through a future
development permit from the City of Renton. The soil overtop of the perforated portion
of the system must not be compacted or covered with impervious materials.
