MEETING DATE: A9I�I� My Of San Luis OBISPO 10-4-94 VMS COUNCIL AGENDA REPORT ITEM NUMBER: /J FROM: Michael D. McCluskey, Public Works Director\ PREPARED BY: Morris D. Witbeck, Engineering Assistant SUBJECT: Waterline, Sewerline, and Traffic Signal Improvement Project, Specification No. 94-12 Location: Higuera St. - Marsh to Broad, and Marsh St. - Higuera to Santa Rosa. CAO RECOMMENDATION: By motion, 1)approve the plans and specifications for"Waterline,Sewerline,and Traffic Signal Improvement Project: Higuera St. -Marsh to Broad, Marsh St. - Higuera to Santa Rosa," Specification No. 94-12; 2) authorize the solicitation of bids; and 3) authorize contract award by the CAO if the lowest responsible bid is within the Engineer's estimate; 4) authorize appropriation of $100,000 from 1993-94 Water Fund balance; 5) authorize allocating up to $7,500 ($5,000 direct contribution plus up to $2,500 in matching funds) to the BIA/Merchant Association for promotion and advertising to mitigate economic effects of the project. DISCUSSION: The Utilities Department, through an analysis of all existing sewer and water lines has determined that water and sewer lines must be replaced in Higuera Street and in Marsh Street The lines requiring replacement in Marsh Street consist of the following: a sewerline from Nipomo Street to Santa Rosa, and a waterline from Higuera Street to Nipomo Street. The improvements in Higuera Street consist of a waterline in Higuera Street from Broad Street to Marsh Street. These replacement projects are due to deteriorated existing lines, which have required extensive maintenance due to breakages, infiltration and inflow, and blockages. The Utilities Department's computer program has adequately sized the-new waterlines to provide fire flow as well as domestic service to the commercial core of the City. The proposed project offers a unique opportunity to obtain traffic signal interconnect communication lines at a minimal cost to the City. Presently Pacific Bell telephone lines are used to achieve signal coordination. These "phone drop" lines cost the City approximately $40 per month for each signal on the phone system. Past reliability of this portion of the signal system has been intermittent, and the utility has provided little assistance with trouble-shooting problems with the system as they have been encountered. This degrades the ability of the signal maintenance forces to detect and correct problems with the system as they occur. The major expense of installing private dedicated lines is in the cost of trenching. Combining this signal interconnect project with the proposed project will result in greater signal system reliability, reduced installation and operating costs,fewer patch marks in the street, and provide an additional link in the future connection of the Corporation Yard with City Hall via light cable communication. Mitigation Measures: Significant mitigation measures have been included in the specifications for this project These measures were developed in cooperation with the Downtown Merchant Association(the BIA) during the hearings held on the Higuera Street waterline project, which was previously constructed in the downtown area. Mitigation measures developed with that project,which are included in this project, city of San Luis osisp0 Mi ma COUNCIL AGENDA REPORT Specification No. 94-12 Meeting of October 4, 1994 Page Two. include the following: 1) No two contiguous blocks of construction shall take place at any time; 2) . on-street parking removal will be minimized with each construction activity; 3) all trench work will be backfilled and/or plated over prior to the conclusion of each work day's activities; 4) work will cease early on Thursdays so as to not disrupt Thursday night activities.; 5) all water service tie-ins Will occur at night to prevent disruptions to existing businesses, and all water service connections will be coordinated with each customer to minimise the impact on their activities; 6) a promotion and advertising campaign will take place to promote businesses in the downtown area while construction takes place; 7) construction will take place just after the New Year's holidays, and conclude before the high tourist season commencing in late spring. In order to make the project occur in accordance with the wishes for construction timing (after the holidays), staff is bringing this project forward for approval in order to receive bids, award, receive insurance documents,and make all necessary approvals to allow construction to start in early January of 1995. A town hall meeting with businesses and residents affected along Higuera Street and Marsh Street was held in the City/County Library room on Tuesday, September 27, 1994 at 8:15 A.M. City staff provided an overview of the project and the need for the project to those who attended. The BIA made arrangements and set the time and place for the meeting. In order to keep the project on schedule, this agenda item must be prepared prior to the results of the September 27th meeting. Should additional mitigation measures be necessary, or a change in the promotion program be a result of the September 27th meeting, staff will inform the Council of those decisions prior to the City Council meeting. CONCURRENCE: The Community Development Department has determined that this project is categorically exempt from further environmental reviews. Staff is assuming that as all mitigation measures which have been included in this project have been included in previous downtown projects, no additional mitigation measures will be required, and thus the project has the concurrence of the BIA. FISCAL I14IPACT: As detailed in the Engineer's Estimate, the total estimated cost for this water, sewer, and traffic signal project is $805,000 (including contingencies), as summarized below: WATER MAIN SEWER MAIN TRAFFIC SIGNAL Construction - $415,000 $295,000 $21,800 Contingencies @ 10% $ 41,500 $29,500 $ 2,200 Total $456,500 $324,500 $24,000 Funding Available $472,000 $325,100 $193,900 ��►� � ►��i�pnll city of San Luis OBISPO 11jig COUNCIL AGENDA REPORT Specification No. 94-12 Meeting of October 4, 1994 Page Three. The 1993 Financial Plan (page E-5) identified $700,000 for 1994-95 water distribution improvement projects and $305,500 for 1994-95 wastewater collection system improvement projects. The 1994-95 water distribution CIP program has a remaining balance of $372,000, which is not enough to fully pay for the proposed project. Completion of downtown projects with minimal interruptions to the businesses and customers is a high priority, so repairing or replacing as much of the deteriorated system as can be reasonably accomplished in one project is a staff objective. Staff recommends that $100,000 be appropriated from water fund balance to support a slightly expanded water improvement project from what was originally estimated at the time of financial plan preparation. The appropriation from fund balance is available from 1993-94 water operating savings returned to fund balance, so this does not affect the integrity of the annual water fund revenue requirement The current wastewater collection capital improvement program has a current balance of$325,100, including about$20,000 remaining from the collection improvement CIP funding from 1993-94. This is enough to support the proposed project Page E-6, 17 of the 1993-95 Financial Plan for Traffic Signal Improvements has identified $193,900 in available funds to support this portion of the project.
