Item #7 CITY OF COLTON AGENDA REPORT FOR THE CITY COUNCIL MEETING OF MARCH 16, 2004 TO: HONORABLE MAYOR AND CITY COUNCIL MEMBERS FROM: AMER JAKHER, P.E., CITY ENGINEER SUBJECT: APPROVE RESOLUTION APPROPRIATING ADDITIONAL FUNDS FOR DESIGN OF COMPREHENSIVE STORM DRAIN PLAN NO. 3; PROJECT 3-5, PHASES I, II, AND III AND AUTHORIZE THE AWARD OF CONTRACT FOR THIS PROJECT IN THE AMOUNT OF $387,055, TO ENGINEERING RESOURCES OF SOUTHERN CALIFORNIA, INC. DATE: MARCH 8, 2004 BACKGROUND: Comprehensive Storm Drain Plan No. 3, Project 3-5 originated in 1973. Original recommendations for project 3-5 included a turnout exiting the East Rialto Channel into Mill, Pepper and Randall Basins plus a reinforced concrete channel to the Santa Ana River. In 1986, the Cities of Colton and San Bernardino Funded an Engineer's Report, prepared by County Flood Control District staff, which evaluated 12 alignments including retention basins, subsurface storm drains and open channels. In 1995, the County of San Bernardino and the City agreed upon a Memorandum of Understanding (MOU) establishing the terms and conditions for the design and construction of various transportation, flood control and infrastructure improvements relative to the construction of the Arrowhead Medical Center. Agreed upon improvements included a portion of the construction of Comprehensive Storm Drain Plan No. 3, Project 3-5 (Project 3-5) in Meridian Avenue from Valley Boulevard to San Bernardino Avenue. This portion of Project 3-5 is identified as Phase 1 in the 1995 MOU. These improvements provided little or no mitigation of the flooding that occurs along Valley Boulevard. The current designed, Project 3-5 is aligned along the extension of Pepper Avenue south of Slover Avenue. Environmental documentation for Project 3-5 identifies certain mitigation measures necessary to minimize impacts to the Delhi Sands Flower Loving Fly and its habitat along portion of the alignment and between the railroad and Interstatel0. Unfortunately, costs associated with construction methods required to minimize habitat damage and the purchase and endowment of habitat offsets have resulted in an overall project cost that renders the current alignment of project 3-5 economically unfeasible. Therefore, the City of Colton elected to analyze additional alignments which may be more feasible from an economic and environmental point of view.
