Item #14 CITY OF COLTON AGENDA REPORT FOR CITY COUNCIL MEETING OF JULY 16, 2002 To: Honorable Mayor and Members of the City Council From: Kathy A. Kivley, Assistant to the City Manager�• Subject: Approve the recommended preliminary desi n rnativefo a grade separation at Hunts Lane Date: July 9, 2002 BACKGROUND The City applied for and received State funding to design and construct one grade separation. This grade separation, located on Hunts Lane, over the Union Pacific Railway track near Club Center Drive and Steel Road is in both the City of San Bernardino and the City of Colton (Aerial Image and Location Map attached). The Hunts Lane Project is a joint project with the City of San Bernardino and San Bernardino Associated Governments (SANBAG). The Hunts Lane crossings is currently experiencing over 50 trains per day up to 1-1/2 miles long, projected to go to over 100 trains per day in the year 2020. The project is 100 percent funded through the State Transportation Congestion Relief Program (TCRP) based on the preliminary estimated total costs of approximately $17.2 million. At the request of both local agencies, the City of San Bernardino and the City of Colton, SANBAG took the lead in developing the TCRP-funded grade separation project. DISCUSSION /ANALYSIS SANBAG awarded a Preliminary Engineering Contract for the Hunts Lane Grade Separation Project. Moffatt & Nichol Engineers was selected to design the grade separation at Hunts Lane. For the past several months, the engineering consultants and the Project Development Team (PDT), including the Assistant to the City Manager, City Engineer and Engineering Supervisor, other affected jurisdiction staff, and SANBAG staff, engaged in extensive alternatives development and evaluations of the respective alternatives for the project. Following are the results of those efforts: Four improvement alternatives were evaluated for the Hunts Lane project: 1. Hunts Lane overcrossing the railroad track. 2. Hunts Lane undercrossing the railroad track 3. Railroad track under Hunts Lane 4. Railroad track over Hunts Lane All scenarios were intended to maintain existing rail and vehicle access through the project site during construction. Alternatives 2 ($24,000,000), 3 ($41,000,000) and 4 ($33,000,000) were ruled out early in the process primarily due to the prohibitive costs associated with building the structures necessary to avoid the high water table level, dewatering costs, major pipeline relocations and to support the trains and the length of approach track necessary to meet the required maximum rail grades. The attached brief evaluation matrix reflects the estimated construction cost for each alternative. The estimated construction cost of Alternative No. 1 is approximately $14 million.
