Underground utilities shall be provided on common driveways,
unless the Planning Board makes findings in open meeting that underground
utilities are not practical due to extreme topographical or environmental
constraints and/or safety issues. Aboveground utilities shall not
be allowed solely for the convenience and/or preference of a petitioner.
(16)
Applicants must provide drainage calculations relative to the
Massachusetts Stormwater Handbook, and propose appropriate mitigation
for impacts to stormwater quantity and quality.
(17)
An occupancy permit for any structure accessed via the common
driveway shall not be granted until the house numbers of the lots
serviced by the common driveway are clearly posted on a single permanent
post at the street so as to be visible from both directions of travel,
and are also posted on a permanent post at the point at which each
private driveway splits from the common driveway.
(18)
An occupancy permit for any structure accessed via the common
driveway shall not be granted until the common driveway is 100% complete.
In order to be considered complete, the design engineer must submit
a stamped letter certifying the common driveway site work has been
constructed as shown on the approved plans.
