Surfacing:

Crushed gravel chips on a tack coat over a medium type pavement
(i.e. 2″ of surface over 4″ of bituminous concrete, over a 5″crushed
stone base) is adequate for parking areas in urban centers. Avoid
smooth hot asphalt surfaces because leaves tend to make the surface
slippery. Striping is a necessary evil to control density unless
numbered posts are used. Parking meters serve the same purpose in
municipal and commercial areas. I prefer posts.
