I have a situation I had not run into before. I am working on a design for a military installation, the site is dedicated to this single property facility.
1. IBC 506.2 does not address whether the "public way" needs to be flat. In my case the bldg is surrounded by a ~20' wide utility road surrounding the building, and on the outside of this is a gravel embankment which is on average 20' wide, and has a 1 in 5 slope. (I.e. 1' rise every 5' on one side, and 1' drop every 5' on the other side of the bldg, thus it is not flat and could be difficult to negotiate for some people.) Outside of this is the parking lot with fire road. We have the embankment because the bldg site is sloped.
=> Can we take full credit for a 30' frontage increase? We essentially have 100'+ all around the bldg, the catch is that sloped gravel embankment.
2. If the answer to the above is "no" because the embankment is not a public way , then we would like to apply IBC 506.2.2 for "open space". However the fire road can be 60' away in some places. Does that count as "accessible" to the fire department? What on average IS the maximum distance a fire road can be located from a bldg and still be considered accessible?
Thank you in advance for any insight.
