The integrated Storm Water Management (iSWM) Design Manual for Site Development was developed through the North Central Texas Council of Governments (NCTCOG) in January of 2006. NCTCOG updated the iSWM Manual format in April of 2010. Freese and Nichols, Inc. is currently updating the existing City of Dallas drainage criteria by implementing the new iSWM Manual.

The iSWM Manual includes design standards and tools that can be used to address the quality and quantity of storm water runoff on and from development sites. The manual was developed by NCTCOG to guide developers and governmental agencies on the control and management of storm water at all stages of a development project.

The objective of this project is to update the existing City of Dallas Storm Water Design Criteria Manual to incorporate the criteria included in the iSWM Manual. This will be achieved by inserting local provisions into the iSWM Criteria Manual. The Local Provision Boxes within the iSWM Criteria Manual include standards and development processes that are specific to the City of Dallas. A draft version of the Dallas iSWM Criteria Manual is available on the Public Documents page. Developers and other public and private entities are strongly encouraged to review this document and provide their input by visiting the Public Input page.

A class "How to Use the iSWM Approach in Dallas" is being offered on Tuesday, August 17, 2010 from 8:30 am to 12:30 pm. The class includes credit for professional development hours.
