Marina/I-880 Traffic Impact Fee 2 May 3, 2010 In approximately 2012, the Alameda County Congestion Management Agency (ACCMA) plans to construct an additional south bound lane on I-880 for use by high occupancy vehicles (HOV). This expansion will require installation of a new bridge, or overcrossing, at Marina Boulevard. The City is working with the ACCMA to have the bridge and connector ramps upgraded to accommodate the projected traffic in 2030. In 2008, the cost of these upgrades was estimated at $27,000,000 (design, permitting, and construction). The Kaiser Permanente project at 1701 Marina Boulevard will generate significant traffic at this Interchange. Specific improvements are required to address hospital-related traffic and Kaiser has paid the City its estimated fair share of these costs. Analysis The City's Development Fee for Street Improvements (DFSI) levies a fee upon any new development that will impact city traffic. However, the proposed Marina/I-880 Interchange improvements are not listed in the Master Plan of City Streets and are not covered by the existing DFSI fee. The City cannot recover costs from additional traffic at the Interchange caused by existing development or from trips that originate or terminate outside the city. Only new development within the city can be required to contribute to the improvement project, and the contribution can only be in proportion to their use. The City has the authority to adopt administrative regulations that establish zones of benefit for area-specific traffic improvements that are required to maintain the City's defined level of service. The purpose of this proposed supplemental traffic impact fee is to fund improvements at the Interchange that mitigate the impacts of increased traffic due to new development within a zone of benefit. The proposed supplemental impact fee will be implemented by amending the City of San Leandro Administrative Code to include a new section, number 8.10.320. The addition specifies the amount of the fee for each land use and states the fee will be collected until $2,540,271.24, adjusted by the change in the San Francisco Construction Cost Index as published in the periodical Engineering News Record, has been collected. The same index is used to adjust the existing DFSI rates. Traffic Analysis/Forecast Details Traffic volumes were forecast to the year 2030 using the bay area traffic model maintained by the ACCMA. An analysis of the forecast was performed by TJKM Transportation Consultants, and submitted in a traffic report entitled "Traffic Impact Fee Analysis for I-880/Marina Interchange Improvement". The model indicates that in 2030 there will be 14,814 daily trips over the Interchange during peak hours. Apportioning the 2008 cost of the improvements to each trip evenly results in a cost per daily trip of $1,823. Inflation from 2008 to 2010 has raised the cost of improvements to $28,734,835 and the cost per trip to $1,940.13.
