As a part of this work, the CITY proposes to cover the bypass channel from Murwood Drive to San Ramon Creek and to construct a box culvert to support a roadway.

FINANCIAL RESPONSIBILITIES: The CORPS has estimated the costs for the cover, culvert and channel modifications work as follows: Construction 568, 600 Contract Supervision and Administration 42, 600 Engineering and Design 155, 000 Extra Cost for Additional. Insurance 2, 000 Estimated Total Cost 768,200 The figure stated in the preceding paragraph for "Construction" constitutes the CORPS ' estimate of the construction cost attributable to the cover, culvert and channel modifications at the time of bid. The construction cost includes a 25 percent share of the cost of the CMU Retaining Walls from Sta. 595 + 20 to 596 + 75, from Sta. 603 + 62 to 604 + 78 and from Sta. 610 + 18 to 625 + 44 . Once the actual construction bid cost for the entire San Ramon Creek Bypass Phase III Project has been determined, the construction cost attributable to the cover, culvert and channel modifications shall be recalculated by multiplying 0. 05751 by the total as-bid project construction costs. Said 0. 05751 is based on the government estimate for the work and represents the percentage of total construction cost attributable to the cover, culvert and channel modifications at the time of bid. It is the intent of the parties herein to have the CITY pay the entire cost of change orders or extra work attributable to the cover, culvert and channel modifications and the DISTRICT pay the entire cost of change orders or extra work attributable to the channel. - Each party shall have a right to written approval of change orders or extra work occasioned by request of another party which will result in increased costs to the non-requesting party or alter the specifications provided by the non-requesting party. The additional cost or associated credit to the CITY arising from contract change orders or extra work shall be determined on a case-by-case basis and such additional cost or credit shall be assessed separately and shall not affect the established 5.751 percent used to determine the initial cost to the CITY at the time of bid. The figure stated above for Contract Supervision and Administration constitutes the CORPS ' estimate of the contract supervision and administration costs attributable to the cover, culvert and channel modifications. Once the contract supervision and administration costs for the entire San Ramon Creek Bypass Phase III Project have been determined, (but adjusted so as to not include contract supervision and administration costs associated with contract change orders or extra work) the contract supervision and administration costs attributable to the cover, culvert and channel 4 modifications shall be recalculated by multiplying 0. 05751 by the total adjusted project contract supervision and administration costs. Contract supervision and administration costs attributable to the CITY as a result of contract change orders or extra work will be performed on a case-by-case basis; and, such additional cost or credit shall be assessed separately and shall not affect the established 0. 05751 used to determine the actual cost to the CITY. The figure stated above for Engineering and Design is the estimated cost of the engineering and design work performed by the CORPS in conjunction with the cover, culvert and channel modifications work performed under this Agreement. Once the engineering and design costs for local work items have been determined, (but adjusted so as not to include engineering costs associated with Contract change orders or extra work) the engineering and design costs attributable to the cover, culvert and channel modifications shall be recalculated by multiplying 38% by the total adjusted engineering and design costs for local work items. Engineering and design costs attributable to the CITY as a result of contract change orders will be performed on a case-by-case basis; and such additional cost or credit shall be assessed separately and shall not affect the established 38% used to determine the actual cost to the CITY. Pursuant to the allocations and provisions set forth above within this section, the CITY and the DISTRICT agree that it is the intent of the parties that the CITY pay 92 . 6 percent of the costs for the cover and 100 percent of the costs for the culvert and appurtenant channel modifications work; and that the DISTRICT pay 7 . 4 percent of the costs for the cover work undertaken pursuant to this Agreement. The DISTRICT and CITY acknowledge that the - CITY has made advance payments of $250, 955. 22 as of June 29, 1989, thereby offsetting a portion of the total construction cost. Within 24 calendar days of the CORPS ' opening of bids for the project the CITY shall: (A) establish an escrow with a commercial escrow company mutually agreeable to the parties herein; (B) cause to be deposited into escrow a sum equal to the CITY's share of total costs, calculated by the above described method, and any additional costs for insurance less $250, 955.22 ; and (C) execute written escrow instructions in a form mutually agreeable to the parties herein, which instructions provide for the disbursement of the escrow funds pursuant to the requirements of this Agreement. In the event that the CITY fails to establish the escrow account or perform under the terms of this agreement subsequent to the execution of this Agreement by both parties hereto, the CITY shall be responsible for payment of any extra expenses incurred by the DISTRICT due to the failure of the CITY to perform hereunder, including charges for delay as may be levied by the CORPS. 5 The CITY'S share of local costs shall be apportioned in accordance with the above percentages and the quarterly funding requirements reported by the CORPS. A final accounting report concerning the cover, culvert and channel modifications construction, engineering, inspection, insurance and administration costs shall be prepared by the DISTRICT which shall include documentation to justify all costs, including the CORPS ' bidding summary, final pay statement and federal estimate establishing the percentage share of the total project cost attributable to the local work. Said final accounting report shall be produced in a timely manner subsequent to the completion of the federal project audit. The DISTRICT shall release to the CITY any escrowed funds and accrued interest, less escrow expenses, which exceed the CITY's share of said project costs within thirty (30) days of the issuance of the final accounting report. In the event thatthe contract is not awarded, the DISTRICT shall release to the CITY all funds deposited pursuant to the above, except for those costs associated with the inclusion of the cover, culvert and channel modifications in the CORPS ' contract documents, including, but not limited to, the design of the cover, culvert and channel modifications, except for CMU Retaining Walls.

If the CITY determines that the cover, culvert and channel modifications, as constructed, comply with the contract documents approved by the CITY, the CITY shall accept the cover, culvert and channel modifications without delay and notify the DISTRICT in writing of such acceptance. The CITY' s acceptance of the cover, culvert and channel modifications shall not be unreasonably withheld. If the CITY determines that the cover, culvert and channel modifications as constructed, do not comply with the contract documents approved by the CITY, the CITY shall notify the DISTRICT of the deficiencies without delay. The DISTRICT shall thereupon notify the CORPS of the CITY's position and request on behalf of the CITY that the CORPS correct the deficiencies. Upon correction of the deficiencies by the CORPS, the CITY shall accept the cover, culvert and channel modifications without delay and notify the DISTRICT in writing of such acceptance. In the event a dispute arises between the CITY and the DISTRICT or CORPS in regard to the completion and adequacy of construction of the cover, culvert and channel modifications work under this Agreement, the CITY shall set forth in writing a statement of the specific deficiencies which then allegedly remain uncorrected and shall issue an interim acceptance subject to the deficiencies as 6 have been set forth. Until such time as the CITY has accepted the cover, culvert and channel modifications or issued an interim acceptance with a statement of deficiencies as set forth above, no portion of this cover, culvert and channel modifications shall be used or occupied by the CITY or members of the public. The DISTRICT shall not accept the contract work as complete until the CITY has accepted the cover, culvert and channel modifications or, in the event the CITY issues an interim acceptance, the DISTRICT shall accept the contract work with the reservations set forth in the statement of deficiencies.
