Hetland PREPARED BY. Cassidy Rowland Utilities Director Administrative Analyst SUBJECT. Special Engineering Services CAO RECOMMENDATION: By Motion, approve Amendment No. 2 to the agreement to provide special engineering services pertaining to the groundwater program, the Hansen /Gularte Creek Water Rights and the San Luis Obispo Creek Assessment with the engineering firm of Boyle Engineering Corporation, at cost not to exceed $30,000, 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 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. 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 since July. Ongoing engineering scope of services to be provided include: Groundwater Program: Examine the areas identified in the Groundwater Basin Evaluation to establish their viability as a potential source to the City. Attend meetings with property owners regarding property access and permission to obtain well data. Coordinate geophysical testing program and report to City on findings. Determine whether well development in these areas can be implemented to the benefit of the City. In addition, Boyle Engineering would be asked to review use of private wells offered to the City by performing site constraints analysis, coordinating water quality sampling and other activities necessary to make a determination on the use of such wells. Hansen /Gularte Water Ri hits /Permitting: Formulate an opinion regarding the status of the City's water rights on the creeks. This would be coordinated with the City's water rights attorney, the State's Water Resources Control Board and other regulatory agencies.

The focus of the assessment is to quantify the portion of creek flow contributed by the Hansen /Gularte diversion works and to identify other sources of tributary flow. Foothill/Reservoir No. 1 Hydraulic Analysis: Complete the computer model for these two water system pressure zones and continue with the hydraulic analysis of zone operations. Provide the City with data diskettes for the computer model plus a node and pipe map indicating the pipe numbering system. Prepare a letter report regarding the facilities needed to operate both zones as a single hydraulic zone. FISCAL IMPACT These specialized engineering services were not originally identified in the 1989 -91 Financial Plan as they result from the ongoing water supply projects due to the drought conditions. On July 3, Council approved $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; Amendment No. 1 was approved on October 2 for $40,500 bringing the total cost to date to $60,500. The funds for this phase 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 Oct 2 Amendment No. 1, funded from Carry-Over 40,500.00 Amendment No. 2, funded from Carry_over 30.000.00 Total For Special Engineering Services $909500.00 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 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.
