I am on an environmental commission in my town. We are interested on information on driveway pavers. Does anyone know if they are pervious? Does the sub base used make a difference. I would really appreciate help with this.

Yes and no...

Unit pavers by themselves are impervious. They're made of concrete. What might drive a field of pavers to be considered pervious would be the manner in which they're installed, and there are a multitude of possibilities. If the pavers are installed over an asphalt or concrete base, they would make an impervious surface. If they were to be installed over a sand or stone dust base, they might be considered partially pervious as the joints between the blocks, assuming no mortar, would allow for some water to penetrate. Then again, those joints, over time, will tend to fill with fine dust and debris making them less and less pervious. Some pavers can be set apart further with wider joints allowing for more infiltration between blocks. Some pavers require very tight joints allowing for less infiltration between blocks. And if the slope at which the field is graded is steep, runoff will tend to pass right over the joints, as it will not take much water to render the joints saturated.

Soooo....yes and no. If I had to lean one way or the other, I'd tend toward the 'no'...meaning that I'd tend toward the impervious, especially from an environmental of conservation commission POV. In the town I live in, were I a member of the commission, a project proponent would have to provide some really specific calculations to convince me of his contention that a field of pavers was pervious, and would remain so, if environmental or jurisdictional waters and wetlands were of concern.
