HetlandPREPARED BY: Cassidy Rowlan�}`L Utilities Director Administrative Analyst SUBJECT. Special Engineering Services CAO RECOMMENDATION. By Motion, approve Amendment No. 1 to the agreement to provide special engineering services pertaining to the water distribution and supply system with the engineering firm of Boyle Engineering Corporation, at cost not to exceed $40,500, and authorize funding from 1989/90 Water Fund Carry Over. DISCUSSION The City is in the fourth year of a water shortage and has adopted a Mandatory Water Conservation Program and greatly expanded source of supply and water conservation programs,with particular emphasis on groundwater wells,in an effort to address this critical situation. The .position of Water Division Manager remains vacant and is soon to open again for recruitment. The Utilities Engineer started in July but is not in a position to assume the day-to-day line responsibilities of the Water Division Manager position, including Whale Rock Reservoir, Treatment Plant, Conservation Program and Distribution System. Combined with the ongoing urgent drought situation and the City's expanded efforts in developing new water supplies, all these activities represent a significant workload that must be administered by staff concurrently with ongoing departmental operations. At this time, the Utilities Department has retained Boyle Engineering to assist in key roles of project management, including consultant liaison, bid preparation and direction, and specific project component oversight. Scope of services to be provided include: Groundwater Program: Coordinate the drilling of test wells and related activities; identify site constraints for candidate sites; coordinate water quality sampling; and make recommendations to the City regarding the construction of production well sites. Foothill/Reservoir No. 1 Zone Modeling: As an extension to our current modeling of the Downtown Zone, develop a computer model of the Foothill and Reservoir No. 1 zones. The primary goal of this modeling is to evaluate means of tying the two zones together. In doing so, this would eliminate the need to pump water through the Transfer Pumps as well as the need to manually operate the valve on Grand Avenue which is the current means of filling Reservoir No. 1. Elimination of this energy consumption and avoidance of staff time related to this method of operation is expected to result in considerable cost savings for the City. For this activity, Boyle would expand the Downtown model to include these two additional zones, calibrate the new model, and provide the City with data diskettes for the existing system A node and pipe map indicating the numbering system used will also be provided. ��H��►�►►►IVillll��p��°►��I�IU City Of San lues OBISPO COUNCIL AGENDA REPORT Special Engineering Services for Water Division Page 2 A letter report regarding the facilities needed to operate both zones as a single hydraulic zone will be submitted to the City. Hansen/Gularte Creek S imply: Boyle proposes to assist the City in activating a surface water treatment plant near Reservoir No. 1 which would provide treatment for diverted water from the Hansen and Gularte creeks. This emergency project would enhance the current City water supplies by re-activating this source which has not been utilized since the late 1970's. Services that Boyle would provide are evaluation of the source, selection of a treatment process, and coordination of the plant installation. The City is expected to j assist in the regulatory agency approval process. Downtown Valve.Plan: In the course of calibrating the hydraulic computer model of the Downtown water system, two areas of the system were encountered that would not converge. City staff confirmed that a number of broken valves are restricting flow within these areas. The broken valves are significantly restricting available fire flow and are presenting a safety hazard, particularly in the business district. Also, the malfunctioning .valves make line closures difficult which has resulted in inordinate water losses when line breaks occur. Boyle would work with City staff in identifying these valves, establishing the priority by which they should be replaced, coordinating the preparation of plans and j specifications for"their repair, and being available to answer contractor questions during the bid procedure. FISCAL IMPACT These specialized engineering services were not originally identified in the 1989-91 Financial Plan as they result from the unanticipated vacancy of the Water Division Manager position and increased workload due to the drought conditions. On July 3, Council approved j $20,000 for the agreement for Special Engineering Services with Boyle Engineering, funded from Water Administration/Engineering unexpended salary during the recruitment of the Division Manager. Total cost for this amendment is $40,500 and the funds have been identified to come from the Water Fund Budget Carry-Over, resulting from salary savings and from expenses savings, particularly in the Wells Operations Program: July 3 Agreement, funded from salary savings $20,000.00 Amendment No. 1, funded from Carry-Over 40.500.00 Total For Special Engineering Services $60,500.00 G. 7' ��n��i�NimIIIIIIIIIP°1"°�9�UIil MY Of San LUIS OBISpO COUNCIL AGENDA REPORT Special Engineering Services for Water Division Page 3 Utilities Department Water Fund 1989/90 Carry-Over totals $574,000 and as such is adequate to fund the contract amendment. CONSEQUENCES OF NOT TAKING ACTION i As detailed above, the ability to properly manage the many line and project responsibilities in the Water Division is key during this critical time of drought. Without professional assistance to do this, project completion and smooth departmental operations will be impacted.
