Refinement Period (November 2007–October 2009)

Following submission of the Substantively Complete Long Term Control Plan, the City embarked on a two-year Refinement Period to confirm technical concepts, redefine the plan, confirm costs, and develop other aspects of the Long Term Control Plan. The Refinement Period culminated in the submission of the Final Long Term Control Plan. Twenty-five separate refinement tasks were carried out and are discussed in Section 3.4 of the Final Long Term Control Plan, Volume 1. Key documents from the Refinement Period are included below.

Basin Study Period (April 2006–October 2007)

During this period, basin plans were developed that identified recommended CSO solutions for each of the 10 Combined Sewer Overflow basins. Information contained in these Preliminary Basin Plans was compiled to develop cross-basin alternatives and to prepare the Substantively Complete Long Term Control Plan, which was submitted to NDEE in September 2007. The documents below were further evaluated during the Refinement Period. As such, information contained in the documents below has been superseded by information in the Refinement Period documents and the Final Long Term Control Plan.
