TO PROVIDE PROFESSIONAL ENGINEERING SERVICES FOR THE DEVELOPMENT OF TIlE STORMWATER MANAGEMENT PROGRAM. ADMINISTRATION RECOMMENDATION The Administration recommends that the .City Commission approve a first amendment to the existing CH2M Hill, Inc. contract for professional engineering services for the development of the Stormwater Management Program at a cost of $50,300. BACKGROUND On December 1, 1993, the City Commission approved Resolution No. 93-20980 which authorized entering into a contract with CH2M Hill, Inc. to provide engineering services for a City-Wide Storm water Management Program. The contract documents provide for four phases of work to be added to the contract by amendment and authorize Phases I and II at a lump sum cost of $317,000. Accelerated stormwater planning services are required in preparation for the Series A Revenue Bond Issue. While the overall goals of the master plan remain the same, there is a need to identify specific stormwater management improvement projects early in the planning process. Additionally, a preliminary engineering report for inclusion in the bond issue later this year and additional coordination with the Program Manager is required. ANALYSIS The existing master plan approach will be modified to include the following elements: 1) Preparation of order-of-magnitude cost opinion; 2) Selection of priority basins for detailed analysis, including five basins for analysis during the pilot study which will identify projects for inclusion in the Series A Revenue Bond Issue; 3) Preparation of a preliminary engineering report for theses five basins which identifies stormwater management projects in more detail for the bond issue; and, 4) Provide for additional coordination with the Program Manager during Phases I and 143 II of the Stormwater Master Plan.

This letter addresses Mr. Carlton's comments. On the June 29, 1994, letter providing a general description of the City's Stormwater Management Program, Mr. Carlton requested an updated schedule to complete Phases I and II of the program. We provided an updated schedule with the May 3, 1994, letter we submitted to you describing the required acceleration and modification to Phases I and II to support the Series A Revenue Bond Issue. However, because of the delays in resolving the bond issue needs, that schedule is outdated. We are submitting with this letter a new schedule for completing Phases I and II. In preparing this schedule, we assumed that the basins to be included in the bond issue are selected by September 1994 and the bond issue will be prepared by the first quarter in 1995. On the June 29, 1994, letter providing a summary of the May 3, 1994, letter, Mr. Carlton had some comments on Page 2, Items 1 throug..i. 4. These comments arc addressed by the items below. Item 1 Mr. Carlton stated that development of order-of -magnitude costs from similar experience in the region is included in CH2M IllLL's original scope of work. Our scope of work provides for the development of planning-level present worth costs based on the stormwater management improvement projects analyzed and identified in the master plan (phase II, Task B). Because these costs were required by April 1994, well before any stormwater improvement projects have been identified, we had to estimate costs based on similar experience in the region. Planning-level costs will still need to be developed, once improvement projects are identified. Item 2 Mr. Carlton stated that the additional cost to develop a preliminary engineering report to support the Series A Revenue Bond Issue is $8,000, by modifying the original Pilot Basin Study task. As described in the May 3 and June 29 letters, CH2M IllLL's cost to prepare this report will be $42,100. However, the original CH2M HILL 2828 Coral Way Building, 2828 Coral Way, Suite 440 Miami. Florida 33145-3214 305.443.6401 FAX 305.443.8856 Domingo Rodriguez P~ge 2 August 26, 1994 FLW329.98.PM fee to perform the Pilot Basin Study task is $17,100, and there will be some cost savings ($8,500), because the acceleration of some of the modeling effort that is included in tasks of Phases I and U (phase I, Task G and Phase IT, Task A & B). Therefore, the net additional cost to modify the Pilot Basin Study task to a preliminary engineering report is $16,500. Item 3 Mr. Carlton feels that this task could be eliminated if you and your staff identify 25 basins, from the 100 total delineated basins, to be modeled in detail. However, the master plan ~eeds to address the other 75 basins in some fashion, because citizens living in the basins not selected may question why their basins were net analyzed. This task will provide documentation of the basin prioritization methodology. Item 4 Mr. Carlton questions why our original scope or work does not include any coordination tasks with the Infrastructure Program Manager (CDM). Nevertheless, our original scope of work does not include the level of coordination now requested with the Program Manager. We have discussed with CDM the required coordination not included in our original scope of work. We also submitted a letter to you on July 19, 1994, as a follow up to the June 29 letters. We have not received any comments on this letter. Please call me if you or Mr. Carlton have any additional comments or questions.
