Gilbert, Director of Public Works September 8, 2000 (Council Meeting 9- 20 -00) 1?(4- Subject: Authorize Reimbursement of Ventura County Flood Control District (VCFCD) Costs for the Restoration of Certain VCFCD Facilities Subsequent to the Construction of the Spring Road Bridge [Project 80151 OVERVIEW City staff has been working cooperatively with the VCFCD on a project to remove certain materials from the Arroyo Simi upstream of the Spring Road Bridge. A portion of that restoration effort is required by the permit issued to the City for the construction of the Spring Road Bridge. That portion of the project costs is, therefore, to be funded by the City. The costs for the sediment and vegetation removal project were only recently determined, subsequent to the receipt by the VCFCD of bids for that work. This report requests retroactive approval of agreement by the City to pay the City's share of those contract costs. DISCUSSION A. Bridge Project Completion In June of this year the City Council accepted as complete, the construction of the Spring Road Bridge, subject to final approval by the City Manager of certain work which had not yet been completed. B. Disputed Work The Contractor, TM Engineering, disputed requirements of the VCFCD permit that a) the south levee access road and b) a portion of the streambed be restored to the "pre- project" condition. The Contractor has refused to perform that work. At SprgBrg_venl If i 1 1- Spring Road Bridge: Stream Restoration September 8, 2000 Page 2 the date of the writing of this report, this matter remains unresolved. In light of this fact, the obligation to restore the VCFCD facilities has reverted to the City. Action to recover those costs from the contractor will be considered at a later date. C. Access Ramp In addition to the removal of certain materials from the streambed and the construction of certain repairs to the south levee road, it is also necessary to remove a dirt access ramp to the streambed and to restore the rock rip -rap bank beneath that dirt ramp This dirt access ramp is located near the southeast corner of the bridge. The City's Contractor was directed to leave that access ramp in place in order to allow access for the performance of a pile extraction test. It was subsequently determined that the pile extraction test was not required. In that this work was omitted from the contract by the City, the cost for this restoration work must be borne by the City. D. Upstream Channel Clearing The VCFCD also wishes to undertake the removal of certain vegetation and sediment upstream of the bridge. Accordingly, the VCFCD agreed to prepare plans, seek bids and award a contract for that work, plus a portion of the above described restoration work required by the City's permit. The scope of their contract is briefly described as follows: Description Funded By: 1. Removal of the acce__ss ramp City - -- -- --- - -- -- - -- --- - - - - -- - -- 2. Removal of certain terials City immediately upstream _of the bridge _ - - - -- - - - - -- - - - - 3. Re o a mval of dditional materials from VCFCD the stream between the bridge and a point approximately one thousand feet east of the bridge Based upon the quantities of material calculated for each of the above elements of the work, the City portion is equal to 44.3% of the total. E. Deferred Restoration In that the north levee road is now being used by Security Paving [the City's Contractor constructing the New Los Angeles Avenue Bridge Widening Project], the restoration of that levee road is being deferred at this time and will be constructed by Security Paving when the bridge widening project is completed.

Rock Rip -Rap Restoration It is not known whether or not the rock rip -rap bank under the dirt access ramp is in good condition. Should it be determined after the removal of the dirt access ramp, that rock rip -rap repairs or restoration work is necessary, a contract change order will have to be negotiated. The cost of any negotiated extra for that work would have to be added to the VCFCD contract, and said additional VCFCD costs would have to be reimbursed to VCFCD by the City. G. VCFCD Contract The results of the bidding process conducted by the VCFCD yielded a contract for the above described work. A summary of the cost breakdown of that contract, plus a contingency amount for rock rip -rap restoration if required, is as follows: Description 1 Access Ramp 2 Removals Near Bridge 3 Removals Upstream Sub -Total 4 Plus Contingency (15 %) 5 Contingency for Rock Rip -Rap Total H. Fiscal Impact City ($) VCFCD (S) 9,779.42 27,248.62 0 46,556.71 37,028.04 46,556.71 5,554.21 18,000.00 60,582.25 46,556.71 Total ($) 9,779.42 27,248.62 46,556.71 83,584.75 5,554.21 18,000.00 107,138.96 The above described City reimbursement to the VCFCD would be funded from the Spring Road Bridge Project [Project 80151. There are sufficient funds remaining in that budgeted Project to fund those costs. I. Payment Authorized In order to avoid delays to the VCFCD process for the review and award of the contract for the above described work, the City Manager authorized a letter to be sent to the VCFCD agreeing to reimburse the VCFCD for the cost of the City's portion of the required work, as described and defined in this report. Said letter requested that the VCFCD indemnify the City against any claims arising out of the VCFCD maintenance contract. STAFF RECOMMENDATION Approve prior action by the City Manager to authorize payment to the VCFCD for certain streambed restoration costs in the Arroyo Simi upstream of the Spring Road bridge, as described in the agenda report.
