4.3 STORMWATER COLLECTION AND CONVEYANCEPermanent runoff collection and conveyance practices are linear structuresdesigned to intercept stormwater runoff and convey it downstream in a nonerosivemanner to an appropriate treatment and/or infiltration system.Collection and conveyance systems typically have no water quality benefit;however, in a developed watershed they are often a necessary component of adrainage system and <strong>BMP</strong> plan. Stormwater should be treated as close to thesource as possible to reduce the amount of collection and conveyanceinfrastructure required. Consider low impact development <strong>BMP</strong>s prior toconventional stormwater collection and conveyance systems.Collection and conveyance <strong>BMP</strong>s should be designed by a licensed professionalcivil engineer as part of the <strong>BMP</strong> plan for a project area. A collection andconveyance system should not be installed without a proper plan as to wherethe water is going to be discharged and treated and/or infiltrated. Collectionand conveyance systems should be designed to provide adequate capacity toaccommodate the 10-yr/24-hr storm. Drainage conveyances through a SEZshall be designed for a minimum of a 50 year storm.Conveyance structures installed on private property should not be installed inthe public right of way.TRPA <strong>BMP</strong> HandbookChapter 4: <strong>BMP</strong> Toolkit2012 4.3.1.1-CulvertPage 1
