BACKGROUND The LPFD currently operates two aerial trucks, each being owned separately and deployed in each partner city In addition to the existing aerial truck being at the end of its service life, the equipment storage capacity is severely diminished by the relative short length of the vehicle and the corresponding equipment spaces being taken up by water tanks and fire pumps Due to the limited equipment storage capacity, the LPFD has had to supplement the existing aerial truck with an additional apparatus known as a Rescue which can be retired with the arrival of the TDA apparatus The replacement TDA apparatus is a specialty vehicle designed to bring immediate firefighting capability including emergency equipment to a fire emergency The TDA platform provides benefits to the Department and partner cities in two key areas 1) operational functionality and 2) financial savings Operational functionality is improved through additional storage capacity and increased maneuverability The increased storage capacity is possible due to a longer vehicle with a Tn-Max Foam System for fire suppression This suppression system takes up approximately 1/10th of the space as compared to systems in the currently deployed trucks, allowing for more equipment storage The maneuverability is greatly increased by the ability to steer the trailer section separately from the tractor, which drastically reduces the vehicle's turning radius and increases accessibility into narrow streets and smaller cul-de-sacs found in the majority of new developments The TDAs are of an appropriate length and height to fit in the fire stations currently housing the existing aerial truck Fiscal savings are realized through maintenance savings and the ability to reduce the fleet size Life cycle maintenance and repair costs are expected to decrease as the ability of the TDA to articulate between the tractor portion and the trailer reduces the strain on the body chassis, lessening vehicle stress, tire wear and overall maintenance The TDA's increased equipment storage capability allows the removal of the Rescue support vehicle from the current fleet, a $600k savings at time of replacement DISCUSSION The initial LPFD discussions for moving to a TDA platform were motivated by the approval of both partner cities to reduce street widths and allow for much smaller cul-de-sacs, restricting our long-wheel based aerial apparatus' access to a number of residential areas Over time, a task force comprised of both Command and Line Staff was formed and charged with researching available alternatives to the evolving challenges faced by the department by evaluating the strategies of other local departments and, ultimately, developing design and cost options The task force learned that most of the Bay Area's fire departments had either already migrated to the TDA platform or were actively planning to do so After thoroughly evaluating our current fleet and fire/emergency strategies and how they addressed the changing requirements of our partner cities, it was determined the best alternative was to migrate away from our current long-wheeled based aerial truck to the more agile and capable TDA platform The aerial truck currently in service was scheduled for replacement in the FY 2016-2017 budget, providing the timeframe opportunity and funding to make the change to the TDA platform Page 2 of 3
