are not included in the stormwater analysis report.
· Water mains and service lines will need to be sleeved if they are unable to meet the
minimum required separation to sewer lines defined in §901-9. E.
· The proposed sewer connection will require installation of a sewer manhole in Main
Street at the junction of the proposed subdivision sewer main and the existing Main Street
sewer main, per §901-14.
· The proposed sewer connection will require installation of a sampling manhole centered
on the property line shared by proposed Lot 5 and the Main Street right of way, per §901-
13.
· Sheet C4.0 identifies “ACCESS AND UTILITY EASEMENT” for proposed lots 3,4, and
5, please identify what access is granted by the proposed easement.
· Please identify how lot 5 will be accessed, if lot 5 is to be accessed from Main Street,
then DPW Engineering will need to review and approve any impacts to paving, curb cuts,
and appropriate separation to the intersection.
· The new sidewalk along Old Colony Road should include ADA compliant curb ramps on
both sides of the proposed roadway, and a crosswalk between curb ramps consistent with
the Town of Barnstable’s Standard Crosswalk detail.
· The project will require a road opening/trench permit, a stormwater management permit,
and a sewer connection permit prior to commencing construction.
