Dead-end streets up to 500 feet long, measured from curb face of the intersecting street to the curb face of the dead-end (cul-de-sac, hammerhead), shall use the approved cul-de-sac dimensions provided in the RTC standard drawings (see at the end of this document). Dead-end streets in excess of 500 feet must use one of the approved fire apparatus turn around designs, also included at the end of this document.

D. Grade. The gradient for a fire apparatus access road shall not exceed 12 percent (503.2.7).

E. Angles of approach: Angles of approach/departure shall not exceed 6 percent for 25 feet prior to or after the grade change (503.2.8).
