NOTICE: The DRAFT Erosion Control Manual has been recently updated. The current draft date is August 2009. A Public Review period of this new draft was concluded on 2008. Revisions to address comments received have been completed, as well as revisions related to recent changes in State of Arizona and federal requirements. This version of the Erosion Control Manual is in the process of being forwarded to the Flood Control District of Maricopa County Board of Directors for approval and adoption.
The objective of the Drainage Design Manual, Erosion Control, is to provide guidance to agencies, municipalities, developers, property owners, engineers, contractors and others involved with construction events as a means to comply with the AZPDES (or the NPDES when seeking permit coverage within Tribal Lands) stormwater permitting process for construction activities. Specifically, this document provides guidance on how to comply with the AZPDES (and NPDES) General Permit for discharges from regulated construction activities.
The DRAFT Erosion Control Manual does not include any agency-specific policies and standards. It only contains technical guidance.
The EFFECTIVE Erosion Control Manual (January 1, 1993) is still in effect until further notice, unless the draft manual is specifically identified for use by an agency. For purposes of obtaining a drainage clearance, the Maricopa County Planning and Development Services (P&D) has adopted use of the 2009 draft Erosion Control Manual, as stated on the P&D web site at: http://www.maricopa.gov/planning/BuildingServices/DrainageReviewRequest.aspx
Please address comments and questions to Matthew Oller of the Flood Control District at (602) 506-4663 or mao@mail.maricopa.gov.
