Enter either the percent grade, or degrees in the area provided to see the calculation. Note: For our purposes, the county codes are written based on percent grade. A vehicle measures degrees, so if you are checking to see if your driveway is within county specs, you'll want to enter the degrees below to see the percent grade.

Teller County Driveway Regulations: Negative slope away from road preferred, no more than 4% grade in first 20' of access. 17% max grade on driveways over 150'. 

Park County Driveway Regulations: Access no more than 2% grade the first 10', then no more than 10% grade first 50'. Max 12% grade after first 50'.
