Post Construction Standards Manual (Final)

What the City of Patterson is doing to comply with stormwater standards

Multi-Agency Low Impact Design Standards

The State of California requires small communities to implement development standards to protect water quality under the "General Permit for Waste Discharge Requirements for Storm Water Discharges from Small Municipal Separate Storm Sewer Systems (MS4s) Order Number 2013-0001-DWQ" (MS4 Permit). These requirements are an extension of similar requirements imposed on larger communities (e.g., the Cities of Stockton, Modesto, and parts of the County of San Joaquin.) The development standards, also known as post-construction stormwater requirements, will become part of every regulated community's development process.

The Cities of Lathrop, Lodi, Manteca, Patterson, and Tracy and San Joaquin County (Partners) are collaborating to develop a Multi-Agency Post-Construction Standards Manual to meet the MS4 permit requirement. A typical multi-agency manual will provide consistent guidance for developers and builders working in the region as well as agency staff. During the process of developing this manual, the Partners will hold multiple stakeholder meetings. The stakeholder process will provide opportunities for interested stakeholders to learn about the regulatory requirements and provide input and comments on the manual.

Email the Project Partners to leave comments on the Adopted Manual.

The Project Partners encourage review and comments from Central Valley Regional Water Board staff on the Revised Draft Manual to ensure that the requirements of Provision E.12 are fully met. The Project Partners are receiving comments until Thursday, June 25, 2015, and will prepare the Final Manual for adoption by City Councils and Board of Supervisors.
