·         CS04-05 (24th and Crossgate Relief Sewer)

·         CS04-06 (Wakarusa and Harvard Relief Sewer)

December 2004 – Preliminary Report received, reviewed by City Staff.  The Preliminary Report concluded that several of the relief lines related to the above projects (specifically 21st and Ousdahl to 23rd and Naismith, and Wakarusa and Harvard) are not necessary, resulting in substantial savings of CIP funds.

January 2004 – DRG submits Scope of Services based on needs identified in the Preliminary Report.  This includes a thorough study of two basins and nine sub-basins in the south and west portion of the City (see the attached map).  The studies of these basins will the basis for decision-making regarding the following CIP Projects:
