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 idled trench where it can be soaked into the surrounding soil. The connection is intended to provide opportunity for infiltration of any lunolf that is being conveyed from an impervious surface (usually a toot) 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 8MP site plan and design details must be maintained and may not be changed without written approval either from the King CourIty Water and Land Resources Division or through a future development permit from King County. The soil overtop of the perforated portion of the system must riot be compacted or- covered with impervious materials.
