C.lJ OF SAN BERNARDWO - REQUVT FOR COUNCIL A~ION STAFF REPORT After the construction of all street improvements, including the storm drain system, it was discovered that the sump on Tippecanoe Avenue did not drain properly, and water tended to build up during rainstorms. This ponding of storm water is due to the flat slope from the centerline of Tippecanoe Avenue to the catch basin. The large amount of storm water that drains in Tippecanoe Avenue is greater than the capability of the drainage system to handle on the flat cross slope of the street section. It is proposed that another catch basin be constructed on the east side of Tippecanoe Avenue. This catch basin will be installed near San Bernardino Avenue, and will intercept a considerable portion of the storm water and allevi- ate the flooding experienced at the sump. The cost of these additional drainage facilities is estimated at $16,000.00, and will be done on a time and material basis, as provided in the Standard Specifications. 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. Nineteen be approved. SYNOPSIS OF PREVIOUS COUNCIL ACTION Continued: 04-07-86 -- Change Order No. Seventeen on the agenda to be approved to authorize the Contractor to furnish and install 18 L.F. of 12" CMP on Tippecanoe Avenue at an estimated increase in contract cost 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 the Contractor to construct 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 $4,327,586.00. ,Urg~ncy 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 this work is not done as a part of this project, we will have to suffer with the flooding conditions, or install these facilities at a later' date with City funds. 15-0264 .CITY OF!SAN BERNARDINU =-:.~ CONTRACT <:HANG.DER NO. 19 .
