The Wastewater Collection System Master Plan (CSMP) is a 20-year critical planning document that establishes a clear vision for our community's sewer collection system, a vital framework beneath our City.


The CSMP identifies both short term and long-term system improvements that are needed to address existing condition, existing capacity, and future capacity issues.

CSMP Background and Development

The Sewer Infrastructure Advisory Group (SIAG) is a 16-member panel of community members that were appointed by the City Council in 2012. SIAG worked with City staff to identify both short term and long-term system improvements that are needed to address existing condition, existing capacity, and future capacity issues and develop a plan that addressed all of the issues in the most cost effective manner.

During over two years of CSMP development dozens of public meetings were held, multiple update presentations made to Council, presentations made to various interested groups, and a public open house. The CSMP draft was available for public comment from September 20 through November 10, 2014. A formal process was completed to meet the requirements of adopting the Public Facility Plan (PFP) that included the following:

  • October 13, 2014 Work Session with the Planning Commission
  • November 10, 2014 Public Hearing with the Planning Commission
  • November 19, 2014 Work Session with City Council
  • December 3, 2014 Council Adoption and start of public hearing for the PFP
