undisturbed soil and shall be left in a firm unyielding
condition. All trenches shall be left flush with the
adjoining grade. The Contractor shall set in place, cap
and pressure test all piping under paving prior to the
paving work.
2. Generally, piping under existing walks is done by
jacking, boring, or hydraulic driving, but where any
cutting or breaking of sidewalks and/or concrete is

larger in diameter, except directly in the path of pipe or conduit,
shall be tunneled under and shall be heavily wrapped with burlap to
prevent scarring or excessive drying. Where a ditching machine is
run close to trees having roots smaller than two (2) inches in
diameter, the wall of the trench adjacent to the tree shall be hand
trimmed, making clean cuts through. Roots one (1) inch and larger
in diameter shall be painted with two coats of Tree Seal, or equal.
Trenches adjacent to tree should be closed within twenty-four (24)
hours; and where this is not possible, the side of the trench
adjacent to the tree shall be kept shaded with burlap or canvas.

the Contractor shall make such adjustments prior to
planting. Adjustments may also include changes in nozzle
sizes and degrees of arc as required.
