(G) Where a storm sewer, culvert, open channel, catch basin, inlet, manhole, or other drainage structure lies outside the public right-of-way, easements of sufficient size as determined by the Village Engineer shall be provided to assure easy access and maintenance.
(H) Sub-surface drainage such as underdrains may be required at the discretion of the Village Engineer.
