SPECIAL CONDITIONS:

Overflow parking areas need not be paved when they are only used
occasionally. Overflow parking areas can be inconspicuous. You
might consider stabilized turf rather than pavement. Lay down eight
inches of #3 stone to grade; puddle the voids with topsoil, then seed
with a deep-rooted grass (Kentucky Bluegrass). Be careful to let
the grade of the topsoil be slightly below the surface of the stone.
