Storm Water Quality Assessment (SWQA)

Bioretention facilities are engineered landscape features that provide storm water treatment and mitigate runoff impacts to the downstream habitat.All development and redevelopment projects applying for discretionary or administrative permits are subject to a formal Storm Water Quality Assessment (SWQA) determination.   The objective of the SWQA is to provide a consistent and thorough method for the initial review of development and redevelopment projects, with the purpose of categorizing projects and determining applicable Storm Water Quality Management Plan (SWQMP) requirements. The SWQA determination also demonstrates to the Regional Water Quality Control Board (RWQCB) that each project receives a consistent review and enables the City to document project categorization and satisfy Municipal Permit requirements.

The formal determinations are based upon a review of the project application submittal.  The minimum amount of information necessary to perform a SWQA Determination includes:

Upon review completion, the projects will receive a formal SWQA determination indicating the type of storm water document required to meet Municipal Permit and SWQA requirements.  Development and redevelopment projects are categorized as:

  • Projects not subject to SWQMP requirements (Exempt Projects)
  • Standard Development Projects (SDPs)
  • Priority Development Projects (PDPs)
