FARRELL, DIRECTOR OF ENGINEERING 02?� SUBJECT: CSOD ADMINISTRATION, CREW, AND WAREHOUSE FACILITY IMPROVEMENTS Over the last four years, the Board and staff have developed and considered many alternatives for addressing the deficiencies at the CSO facilities in Walnut Creek. In 2006, an Ad Hoc Board Committee was formed to work more closely with staff in evaluating and refining alternatives, and four committee meetings were held over the last year. Staff believes that the best alternative is to construct a new 22,500 square foot administration /crew /warehouse building at the location of the existing warehouse at CSO. The recommended project is shown on the attached floor plans and site plan (May 2007 Single Building Concept and Site Plan - Figures 1, 2 & 3). The total estimated cost for this project is $13M in today's dollars. During the development of this project, District engineering staff and our architect have worked closely with CSO staff to be sure that the proposed design meets their needs and creates a positive work environment. Staff will review the key benefits and features of the recommended project with the Board at the workshop scheduled for May 15, 2007. Appendix A (attached) summarizes the changes and refinements made to the design concept since the initial design was developed in 2004 and compares the proposed new facility with the existing facilities.

The single building concept began as a very schematic concept that allocated the space needs from the original needs assessment. This needs assessment included meetings with staff to understand their work practices and the associated space needs and appropriate adjacencies. The original concept was approximately 28,000 square feet in size. In an attempt to reduce costs and ensure that all space was being used efficiently, this original concept was refined to the concept presented in August 2006, which was the basis of the award of the architectural design contract to Calpo, Hom and Dong. The August 2006 version was 25,000 square feet in size. The 3,000 square foot reduction from the original building was achieved, primarily, by reducing the conference room area and eliminating the area for pumping station crews. The architect proceeded to develop a more detailed floor plan and elevations for the 25,000 square foot August 2006 version. When these plans were brought to the Ad Hoc CSO Committee for review, there was a request to further refine the design to reduce the costs. Staff studied the August 2006 version and was able to develop a further space reduction of 2,500 square feet. This was done primarily by reducing the number of staff that can be accommodated in the crew room, the men's locker room and the woman's locker room. In addition, the warehouse size and the size of the expansion area were reduced. The refined May 2007 version is 22,500 square feet in size. The revised version still contains room for growth but not as much as was contained in the original August 2006 version. Staff is comfortable that the modified version will meet our CSO needs for the foreseeable future. The estimated cost of the facility has been reduced from $14 million for the August 2006 version to $13 million for the May 2007 version. The attached "Chronological Comparison of Alternatives" Table A -1 shows the three single building versions and compares them to the existing facilities. The "Summary of Changes" Table A -2 highlights the differences between the August 2006 and May 2007 building design concepts. Figures A -1 and A -2 show the original conceptual layout and Figures A -3 and A -4 contain the layout discussed with the Board in August of 2006.
