Is gravel considered impervious surface?

Yes. It is difficult for water to soak into a packed gravel surface. Once gravel is compacted, from cars or heavy equipment, for example, surface water runs off of it much like a paved surface. The gravel may slow the flow of water from the area, but will only reduce the amount of runoff minimally, if at all. Many flat roofs are covered with gravel, but they still shed the rainwater that falls on them. In addition, if cars or heavy equipment are traveling on these gravel surfaces; runoff typically carries pollutants like metals or petroleum into our waterways.
