DRAINAGE AND GUTTERSDRAINAGE AND GUTTERS The matter of road drainage
is a most important one, and yet it is
often slighted or overlooked. In heavy
clay types of gutter construction and penetration
macadam construction, soils underdrainage
is provided by laying, under the center
of the road, a line of 4-inch agricultural
tile. Gutters for surface drainage, together
with the necessary catch basins, are provided
where there is any considerable slope.
These gutters may be cobbles, granite or
Belgian block, brick, concrete, or grass,
depending on grades and the amount of water
to be taken care of. Of all these the grass
gutter is the best looking, though somewhat
difficult to maintain. It has the great
advantage of lessening the apparent width
of the road, for it appears to be a part
of the adjoining lawn. With the concrete
or granite block gutter a low curbing can
be used, which prevents cars from running
off and keeps the road material off the
lawn, but such a curb also contributes
to the drive a hardness of outline that
is often undesirable. on
