Design & Construction Standards
Clean Water Services Design and Construction Standards cover the administrative and technical requirements for the design and construction of sanitary and surface water management systems which are built as part of residential or commercial development.
On June 1, 2007, updated Design and Construction Standards Resolution and Order (R&O 07-20) take effect.
The new Standards shall take effect for all development and construction permit applications received on or after June 1, 2007. More specifically:
- New land use and building permit applications accepted by the land use authority on or after June 1, 2007 must be accompanied by a Clean Water Services Service Provider Letter dated on or after June 1, 2007 or one dated before June 1, 2007 which specifically references compliance with this Resolution and Order.
- Modifications to Service Provider Letters for land use or building permit applications which were accepted by the land use authority before June 1, 2007 will be reviewed and processed for compliance with the rules under which the Service Provider Letter was originally issued.
- Construction drawings submitted for Site Development and/or Erosion Control Permits will be reviewed under this Resolution and Order if initially accepted by the District/City on or after June 1, 2007; earlier submittals will be reviewed under R&O 04-09.
The updated Standards were developed with extensive stakeholder input. Learn more.
Current Standards (through May 31, 2007)
The current Design and Construction Standards Resolution and Order 04-9 (R&O 04-9) became effective on March 1, 2004 and replaced R&O 03-11. Unless otherwise specifically identified in the land use conditions of approval, new development submittals within the District's boundaries—including development within cities—should comply with R&O 04-9 until the updated Standards take effect on June 1, 2007.
