Jern~anis Ci . ~ Manager RESOLUTION APPROVING CONTRACTUAL SERVICES AGREEMENT WITH TJKM TRAFFIC CONSULTANTS RELATING TO THE DEVELOPMENT OF A TRAFFIC IMPACT FEE FOR THE MARINA BOULEVARD/I-880 INTERCHANGE, PROJECT NO. 120-28-] 72 The subject contract provides for the preparation of a traffic study that allocates the source of future demand for the Marina Boulevard / I-880 Interchange to new development throughout the City for the development of a traffic impact fee. SUMMARY AND RECOMMENDATION Staff recommends approval of a contractual services agreement with TJKM Traffic Consultants in the amow~t of $36.920 for preparation of a traffic study that allocates the source of future demand for the Marina Boulevard/I-880 Interchange to new development throughout the City for the development of a traffic impact fee. BACKGROUND Marina Boulevard is an arterial street within the City that crosses over I-880, a state highway. The overcrossing currently carries an average daily traffic (ADT) of 45,500 vehicles per day in 2 travel lanes each direction, which results in a level of service (LOS) F at the two unsignalized on-ramps. By the year 2030, traffic is expected to increase to 60,000 ADT due to future redevelopment within the City resulting in longer delays for drivers. Additionally, the existing overcrossing does not have the recommended vertical clearance above I-880 and has been damaged by vehicles twice in the last eight years. The Alameda County Congestion Management Agency (CMA) is currently in the design stage of a project that will add high occupancy vehicle (HOV) lanes to Southbound I-880 in the vicinity of the Marina Boulevard overcrossing. The CMA project will include replacement of the overcrossing so that the highway can be widened. The new overcrossing will have increased vertical clearance to the freeway below. The City is planning to participate in the project by providing funds for increasing the capacity of the rebuilt overcrossing and re-aligning the connector ramps to improve the LOS along this segment of Marina Boulevard.
