What is an Impervious Surface? A Comprehensive Legal Overview

Definition & Meaning

An impervious surface is a type of surface that does not allow fluids, such as water or other liquids, to be absorbed. These surfaces are designed to be easily cleaned and disinfected, do not retain odors, and enable fluids to bead up and run off rather than soaking into the material. Common examples of impervious surfaces include concrete, asphalt, and certain types of tiles.

Real-world examples

Here are a couple of examples of abatement:

Example 1: A parking lot made of asphalt is considered an impervious surface because rainwater runs off it instead of soaking in.

Example 2: A commercial kitchen floor made of sealed tile is impervious, allowing for easy cleaning and preventing the absorption of spills. (hypothetical example)
