DISCUSSION Heavy rainfall during the early part of February 1998 caused extensive infrastructure damage. In order to perform essential repairs, sole-source contracts were established with two construction firms and a geotechnical engineering consultant, as reported to Council on February 23, 1998 (CMR: 143:98). The purpose of this report is to provide Council with the current status and cost of the emergency repairs. Completed to-date: ¯Repairs to damaged drainage culverts in the Arastradero Preserve. ¯Repairs to roadway and embankment on Los Trancos Road. One lane of traffic had been closed due to the erosion damage. Estimated to be completed by early May 1998: ¯ Embankment and roadway repair on Palo Alto Avenue between Tasso and Webster Streets. The roadway was undermined when a large eucalyptus tree fell into San Francisquito Creek. As a result, one lane of Palo Alto Avenue had been temporarily closed to traffic. Construction of a retaining wall along 100 linear feet of Page Mill Road, approximately three miles above the entrance to Foothills Park to prevent further movement of a slide occurring on the downhill side of the road. The downhill traffic lane has been badly damaged in the slide and two-way traffic is being maintained on one through lane by use of a temporary traffic signal. Repair of a collapsed storm drain near the pedestrian tunnel at the University Avenue Caltrain station, which was causing localized flooding upstream. CMR:185:98 Page 1 of 2 RESOURCE IMPACT .To date, $313,000 has been encumbered 0~ three emergency contracts appro;ced under the City Manager’s authority. Under these contracts, the contractors are compensated for actual labor, equipment, and materials costs, up to a not-to-exceed contract cap amount. Staff is currently in the process of issuing change orders for projected expenditures beyond the initial contract amounts. The primary source of the cost increase is the slide damage repair on Page Mill Road, the extent of which had not been fully identified at the time of the initial funding request. The City Manager has authorized staff to expend up to $500,000 on emergency infrastructure repairs. It is anticipated that the ultimate cost of the emergency repairs will be somewhere between $500,000 and $600,000. Staffwill obtain City Manager approval prior to exceeding the current $500,000 expenditure limit. The final cost remains difficult to estimate at this time. Since there was insufficient time to perform normal investigations and develop design plans, the contractors’ scopes of work sometimes must be adjusted in the field to accommodate unforeseen conditions. Staffwill prepare a report summarizing the total costs incurred upon the conclusion of all of the emergency repair work. As part of the 1997-98 mid-year Financial Report, staffrequested that $1.3 million be moved from the Reserve for Emergency. Of this, $300,000 was to be allocated to the Public Works Department and the remaining $1.0 million be placed in the City Managers Contingent Account to be utilized as needed. The mid-year report has been reviewed by the Finance Committee and will be forwarded to the Council for approval on April 13, 1998. Upon approval of the mid-year Budget Amendment Ordinance the City Manager will allocate funds as needed to cover departments expenses incurred in responding to the storms. POLICY IMPLICATIONS Emergency infrastructure repairs are being accomplished through the use of emergency sole- source contracts authorized by the City Manager. TIMELINE All emergency construction projects are expected to be complete by early May 1998.
