What is the maximum slope of a parking lot within 10 feet of a building?

The maximum slope of a parking lot within 10 feet of a building is set to 2% to ensure proper drainage and accessibility. A slope of 2% is gentle enough to allow for adequate water runoff without creating safety hazards for pedestrians and vehicles. This standard is often associated with accessibility regulations, aiming to provide a safe, functional space for all users, including those with mobility challenges.

A steeper slope can lead to difficulties in navigation for individuals using mobility aids and could potentially increase the risk of accidents. Additionally, excessive slope can impede the effectiveness of drainage systems, leading to water pooling, which may cause damage to both the parking lot and the building. By adhering to a maximum slope of 2% near buildings, designers and contractors can promote safety, functionality, and structural integrity.
