This asphalt patch does not
comply with the COA standards
for work in the ROW. Given the
challenge that the trench is in
the cul-de-sac, square off the
asphalt patch in a manner which
best creates lines parallel and
perpendicular to the flow of
traffic.

More information is needed on
the tap configuration. On the
plan drawings show the tap is on
the water main line, not on the
lateral to the fire hydrant. How
will it be tapped to avoid the
thrust block? Most likely there is
not enough room to tap between
the hydrant valve and 90 degree
bend and thus the tap will need
to be located on the eastern or
western side of the main (before
the valve). The west side should
be investigated as it may
eliminate a bend or two in the
service line closer to the house,
and avoids the sanitary line.
