nc IA | From your drawing -
split the drain - put one under each vehicle - the snow melts and runs to the center - with it in the middle like you show it will be wet / mess / ice if it freezed right where you walk, plus dropping stuff into the drain / tripping / stumbing etc. Don't need a long trench drain, just a 12x12 grate and cement sloped to it under each vehicle.
Definatly slope the door opening cement away - and start it a couple inches inside of the garage, that way the wind won't blow rain under the seal inside if / when the door seal gets old.
Go with 10' wide doors x at 8' tall. Standard 9x7 are too tight for alot of 3/4 tons with extendable mirrors, and too short if there is a bit of a snow drift in front by chance. | |
