In Virginia it is common practice for builders to purchase large quantities of wooded land and to clear and level the entire area.   Why do our land use commissioners allow this practice?

Other states require some of the land to be preserved and there are maximum concrete percentages requirements that can't be exceeded so that the earth can support the drainage required.   These would make happier, healthier communities.  Wooded areas would reduce noise and air pollution and help promote a more sustainable future.
