One of the final steps when a new building is constructed is the paving of the parking lot. Heavy equipment is brought in and a thick layer of asphalt is laid down, creating a smooth surface for vehicles.
While paving is good for drivers, it does have drawbacks for the environment. Water, which once was able to freely soak into the ground, now has nowhere to go. This water ends up as storm water and flows into the nearest catch basin.
