DescriDtionl Base Line S~ Medical Finlllc:e: ( DIV Center Drive to Crestview Avenue Council Notes: 7~262 Agenda Item NO~ . ciTY OF SAN BERr&hDINO - REQUEST ~ COUNCIL ACTION STAFF REPORT Page 1 of 2 Box culverts were constructed many years ago to pass storm water under Base Line Street, at intersecting streets. The culverts at "E" Street, "Fn Street (east side) and Waterman Avenue even flood during minor rainstorms, due to limited capacity. This limitation of capacity is caused by collapsed sections of the deck of these culverts. Since the pavement on Base Line Street is being totally rehabilitated, it seems appropriate to repair and clean these culverts to restore them to their full design capacity. Repairing the culverts as a part of this project will avoid having to excavate the newly rehabil- itated pavement in the future, and eliminate the flooding problem. Short sections of the deck of the culverts at "En Street were removed in order to allow inspection. Removal of these sections revealed that the decks had severely deteriorated, and even collapsed in some areas. The culverts were completely filled with dirt, which precluded a thorough inspection. How- ever, the sections removed clearly indicated that the entire decks had failed, or were in imminent danger of failure, and needed to be replaced. Some repairs will be needed on the culvert at "Fn Street, but the extent of the necessary repairs is not known. The culverts at Waterman Avenue were found to be structurally sound, and were merely flushed to clean them of dirt and debris. Repair and cleaning of these culverts was not included in the plans and specifications for the pavement rehabilitation project, which means that these items. will be extra work. Contract Change Order No. Two will authorize the Contractor to clean and repair these box culverts as necessary, at an estimated cost of $32,000. This amount could be less in the event that the culvert at "F" Street is found to be in good condi tion and repairs are minor. The work will be done on a time and material basis, since the amount is indeterminate. The total estimated project cost, based upon the actual low bid price, contained an amount of $112,597.55 for contin- gencies which can be used to finance the cost for this change order. There will be a balance of $15,979.15 for contingencies after financing Change Orders No. 1 and 2. Cal trans has indicated their concurrence in. this extra work being 86% financed with Federal-Aid Urban Funds. 4-17-91 75-02" cc . CITY 'OF SAN _RJiRDINO - REQUEST ~ COUNCIL ACTION STAFF REPORT Page 2 of 2 Repair of these box culverts will alleviate the flooding conditions, avoid having to excavate the rehabilitated street in the future, and mitigate any potential liability. Therefore, we recommend that Change Order No. Two be approved. 4-17-91 7500264 ;1:: .. " 10....,. CONTRACT ~NGE Baseline AveU ORPU NO Z lliV. NO c.VPPL. NO o _1 1 Ol\ ...... .... Noll!
