Hopefully you have better luck with your apron / grade situation than I did on a project with the City.
Last year I submitted a new single family with a 3 car detached garage. The lane/property sloped 2 feet side to side (parallel to the overhead doors) over a 50' wide lot. With a flat 30' wide garage, the apron would have been almost flat at one end and about 30% grade at the other end, but really averaging 15% and the alley grade could have been raised with some new gravel without affecting any other property/drainage to get us to 0%-20% & 10% average. The City said no chance, we had to work with the current alley grade situation and we were forced to make our apron 10% max at any point. This is only 2 3/8" rise if your garage is .6m from property line. Our options from the City were:
1. Push the garage further back into the lot until the 10% max grade works.
2. Tilt your garage sideways so it follows the alley. Yes. Really.
3. Step each bay of the garage down to follow the grade.
So now the client has a 6" step inside their garage between cars. Sigh.
