1 OW AGENDA REPORT Agenda Item Reviewed. City Manager Finance Director 5 CA MEETING DATE: OCTOBER 16, 2012 TO: JEFFREY C. PARKER, CITY MANAGER FROM: DOUGLAS S. STACK, DIRECTOR OF PUBLIC WORKS /CITY ENGINEER SUBJECT: APPROVE PLANS AND SPECIFICATIONS AND AUTHORIZE ADVERTISEMENT FOR BIDS FOR THE EDINGER AVENUE WELL PROJECT PHASE I DRILLING CIP SUMMARY The plans and specifications for the Edinger Avenue Well Project Phase I Drilling CIP have been prepared and the project is ready to be bid. RECOMMENDATION It is recommended that the City Council: 1. Appropriate $ 1, 800, 000 from the 2011 Water Revenue Bond Fund ( Fund 305) to the Edinger Avenue Well Project Phase I Drilling CIP 60165; and 2. Adopt Resolution No approving the plans and specifications for the Edinger Avenue Well Project Phase I Drilling CIP 60165, and authorize the City Clerk to advertise to receive bids. FISCAL IMPACT Sufficient funds, in the amount of $ 200, 000, have been budgeted for the preliminary design phase of the Edinger Avenue Well Project in the Fiscal Year Capital Improvement Program Budget. Well drilling was planned for FY 2014/ 15. To advance Phase I Well Drilling, 1, 800, 000 will need to be appropriated from the bond proceeds from 2011 Water Revenue Bond issuance. There is a $ 5, 000,000 fund balance in net bond proceeds in Fund 305. DISCUSSION The construction of the Edinger Avenue Well CIP has been advanced to coordinate with the construction of the Residence Inn and the Fairfield Inn by RD Olson Company and to complete the drilling phase of the project before the grand opening and occupancy of the hotels. The proposed project will be implemented in two phases: Phase I Drilling, and Phase II Construction /Equipping. This project will enable the City to improve its groundwater production and reliability. Ultimately, the well will be contained within in a structure that is approximately 2, 000 square feet in size, designed to match and blend with the adjacent architecture and land use. The proposed well will be drilled in two passes ( i. e. pilot borehole and reamed borehole) using the reverse circulation rotary drilling method with installation of a gravel envelope to stabilize the formation materials. 1, 300 feet. A inch pilot borehole will be drilled to an estimated total depth of

Isolated aquifer zone testing will then be performed, the results of which will be used to quantify aquifer yield and ground water quality. This data will be instrumental for preparation of the final well design such that the best possible ground water quality can be achieved. Production rates for the proposed well are expected to range from approximately 1, 500 gallons per minute ( gpm) to 2, 500 gpm. Drilling, construction, development, and testing of the well will require approximately 75 work days to complete ( not including weekends). During that period of time several phases of the work will require 24 -hour continuous operations on the part of the drilling contractor. The number of work days required for each major phase of well installation, and the nature of that work ( i. e., 24 -hour or daylight only) is summarized below: Conductor Installation 1 Daylight Only Mobilization 5 Daylight Only Pilot Borehole Drilling Hour Continuous Isolated Aquifer Zone Testing Hour Continuous Well Construction Hour Continuous Initial Well Development Hour Continuous Demobilization of Drilling Rig / Mobilization of Test Pump & Motor Final Development 7 Daylight Only 6 Daylight Only Step Drawdown Aquifer Test 1 Daylight Only 24 -Hour Constant Rate Aquifer Test Hour Continuous Well Disinfection 1 Daylight Only Gyroscopic & Video Surveys 1 Daylight Only
