THE CITY OF CITY COUNCIL AGENDA REPORT j~L£~S~4NTONe December 16, 2008 Community Development Engineering Division TITLE: APPROVAL OF CONTRACT AMENDMENT NO. 2 WITH KLEINFELDER INC. IN THE NOT TO EXCEED AMOUNT OF $35,000 FOR CONSULTANT ENVIRONMENTAL SERVICES FOR SOIL AND GROUNDWATER SAMPLING FOR FIRE STATION NO. 3 SUMMARY The Alameda County Health Care Services (ACHCS) provides local regulatory oversight of the investigation and cleanup of soil and groundwater contamination from leaking petroleum underground storage tanks. The City has been working with the ACHCS and Kleinfelder, Inc., to process the final inspection of two 500 gallon capacity underground storage tank systems (gasoline and diesel fuel) that were removed from 4444 Railroad Avenue (the site of the new Firehouse Arts Center) and two additional underground fuel tanks that were removed from 3200 Santa Rita Road (Fire Station No. 3) in 1996. The ACHCS has approved (closed out) the tank removals site at 4444 Railroad Avenue and no additional work is necessary. However, the ACHCS has determined that additional work will be required to further investigate the site located at 3200 Santa Rita Road, as soil samples indicate the presence of petroleum hydrocarbons. Staff is proposing an amendment to evaluate existing conditions as required by the ACHCS. STAFF RECOMMENDATION: 1. Authorize the City Manager to approve Contract Amendment No. 2, in an amount not to exceed $35,000, to the professional services agreement with Kleinfelder, Inc. of Pleasanton, California (Attachment 1). 2. Authorize the Director of Community Development to approve and execute contract change orders for a contingency amount not-to-exceed $7,000 (20% of the contract amendment amount), for necessary related project work for a total potential contract value of $42,000. 3. Authorize funding from the General Fund Contingency Reserve in the amount of $42,000 for the subject project. FINANCIAL IMPACT The proposal submitted by Kleinfelder, Inc. is an estimate for determining the horizontal and vertical extent of the petroleum hydrocarbons found at the site. Once the limits of the petroleum hydrocarbons are confirmed, a remediation plan will be developed and implemented. The cost of the remediation plan and associated mitigation efforts are not part of this amendment and will be negotiated once the conditions have been fully assessed.
