New Development

The science of stormwater quality management is evolving and new and innovative control measure technologies are constantly being introduced to design professionals. For this reason, this manual will need to be a dynamic document that will be reviewed and updated periodically.  Manual users are responsible for ensuring that they are referencing the most current edition, by checking www.beriverfriendly.net (New Development) or contacting wrswqpr@saccounty.gov

Construction General Permit

Construction projects that include construction or land disturbance activities that result in a disturbance of one or more acres, or less than one acre but are part of a larger common plan of development or sale that totals one or more acres of land disturbance may be subject to the State Construction General Permit.  For more information, please go to the State Water Resources Control Board website.

  • Page 3-12 of the Design Manual does not recommend projects that employ extensive BMPs to use the spreadsheets.  To use the spreadsheets, individual BMPs with respective sub-sheds can be used and then weighted against the total shed area.
  • If there are multiple Points of Compliance (POCs), each POC must reach 100 points.
