'L CIYI OF SAN BERNARDWO - REQU'iT FOR C:OUNCIL A1iION STAFF REPORT After the construction of three driveway approaches leading to the service roads on the Santa Ana River levees, the Flood Control District requested that these approaches be widened from 16 to 36 feet. The District explained that these driveways are going to be used on a daily basis by large trucks carrying broken concrete and pavement from construction sites, to be disposed of along the sides of the river levees. This volume of truck traffic was not known until after the driveways had been constructed. In order to reduce the. public liability of trucks making a turning movement in and out of these driveway approaches, we recommend that the driveways be widened to 26 feet, in order to prevent trucks from swinging into another traffic lane, and possibly creating a traffic hazard. This work will be done on a labor and material basis, at an estimated increase in contract cost of $2,900.00, from $4,343,275.00 to $4,346,175.00. . The total estimated project cost, based upon the actual low bid price, contained an amount of $713,215 for contingencies, which can be used to finance the cost of this change order. We recommend that Change Order No. Twenty be approved. SYNOPSIS OF PREVIOUS COUNCIL ACTION Continued: 04-07-86 -- Change Order No. Seventeen on the agenda to be approved to furnish . and install 18 L.F. of 12"CMP on Tippecanoe Avenue, at an estimated increase in the contract price of $320.00, from $4,325,695.00 to $4,326,015.00. 04-07-86 -- Change Order No. Eighteen on the agenda to be approved, to authorize payment for construction of additional sidewalk under Item 24, to meet handicapped requirements, for an increase in contract price of $1,260.00, from $4,326,015.00 to $4,327,275.00. 04-07-86 -- Change Order No. Nineteen on the agenda to be approved to authorize payment for the construction of a catch basin and approximately 140 L.F. of 24" RCP at an estimated increase in contract cost of $16,000, from $4,327,275.00 to $4,343,275.00. URGENCY CLAUSE The Contractor is nearing completion of this project, and needs authority to proceed in time to complete this extra work before he pulls off the project. In the event these driveways are not widened as a part of this project, the City could possibly be subject to leqal action if an accident occurs. Widening these driveway approaches in the future would be more disruptive and expensive, and have to be financed with City funds. 1s..0264 \lJ.',I; 1 V~ i)/ln JJJ:,l\I1J'I\Ull'V .'
