MAINTENANCE INSTRUCTIONS FOR A PERFORATED PIPE
CONNECTION
Your property contains an on-sitc BMP (bcst managcmcnt practicc) callcd 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 roo fl to a local drainage system such as a
ditch or roadway pipe system. This on-site BMP shall be maintained per Appendix A of the City of
Renton's Surface Water Design Manual.
MAINTENANCE RESTRICTIONS
• The size and composition of the perforated pipe connection as depicted by the site plan and
design details must be maintained and may not be changed without written approval from the
City of Renton or through a future development permit from the City of Renton.
� Thc soil ovcrtop of thc perforatcd portion of thc systcm must not bc compactcd or covcrcd
with impervious materials.
RECORDING REQUIREMENT
These perforated pipe connection on-site 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.13.4 of the City of Renton 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
