the soils. It is not recommended
to have the water service line
within 7' horizontally of the
drywell to prevent freezing of the
line.
Call out water service line to be
located 7' from drywell location
or propose new alignment.

report, this rain garden does not
have an overflow path other than

requires an outlet from the
