Many say that your company will be judged on your ability to recover at a significant incident. Hose Racks, although often used for stand-pipe operations, can be a life saver when needed to extend a line, no matter the environment (high-rise or not). What does your department have in-place for "hose racks"? What uses have you had? What do you carry in the "racks" (spanners, nozzles, etc.)?
On our engine at work we have 1--50' bundle of 1 3/4" and 2--50' bundles of 2 1/2" on top of the rig. As for what we would consider "our rack" we have 100' of 1 3/4" with an Akron Turbojet Fog (break apart) nozzle in a cleveland bundle attached to our 3" dead load with a gated wye. We consider this load as our "inaccessible area hose load/apartment load".
