CITY OF PLEASANTON, CITY OF DUBLIN, CITY OF LIVEl2MORE, AND ALAMEDA COUNTY CONGESTION MANAGEMENT AGENCY MEMORANDUM OF UNDERSTANDING FOR THE EASTBOUND INTERSTATE HIGHWAY 580 LANDSCAPE REPLACEMENT PROJECT IN THE TRI-VALLEY This Memorandum of Understanding ("MOU") records the understanding between the City of Pleasanton ("Pleasanton"), the City of Dublin ("Dublin"), the City of Livermore ("Livermore") (collectively the "Local Agencies" and each individually a "Local Agency") and the Alameda County Congestion Management Agency ("ACCMA") with respect to the replacement of landscape plants that will be removed by the Interstate Highway 580 ("I-580") Eastbound (EB) high-occupancy vehicle (HOV) lane projects in the Tri-Valley (the "Landscape Replacement Project"). Recitals A. ACCMA in coordination with Caltrans proposes to construct Eastbound (EB) HOV lanes in the existing median of I-580 corridor in the Tri-Valley. This project is listed as a high priority project in the Alameda Countywide Transportation Plan and as a strategic surface transportation improvement in Che Regional Transportation Plan (2030) prepared by Metropolitan Transportation Commission ("MTC"). B. The limits of the proposed I-580 Eastbound HOV lane project are the interchange of Greenville Road and Che interchange of Hacienda Drive. This project will remove existing landscape plants for its proposed elements. However, to maintain the aesthetic value of the freeway corridor, the environmental clearance process addresses the mitigation criteria to replace the removed plants. C. The criteria for replacing the existing plants in theI-580 EB limits are described in the approved Environmental Assessment /Initial Study with Negative Declaration for the I-580 Eastbound HOV Lane Project from East of Greenville Road to Hacienda Drive ("EB HOV Neg, Dec."). D. The landscape replacement criteria described in the EB HOV Neg. Dec. (Chapter 2.1.7 Visual Aesthetics between pages 2-56 and 2-61) that would apply to this MOU are summarized as follows: • The median removal of existing plants (oleander) is 6.1 miles iu length. The unit cost for replacing these median plants is $127,300 per linear miles in 2005/2006 fiscal year dollars. The total replacement cost for the median is $776,530. The removal area of the existing plants at the I-580 EB shoulder is approximately 3.4 acres. The unit cost for replacing these planting areas is $42,400 per acre in 2005/2006 fiscal year dollars. The total replacement cost at the shoulder is $ 145,856. March 27, 2008 Page l of 8
