The location of sewer access vaults shall be as determined by the Village Engineer.
b.
Before a permanent type of roadway is constructed, house service stubs are to be installed extending outside of the paved area.

Where a public sanitary sewer capable of serving the subdivision is not located within one-quarter of a mile of any part of the subdivision, but plans for installation of sanitary sewers in the vicinity of the subdivision and capable of serving it have been prepared by the village and approved by the Metropolitan Water Reclamation District of Greater Chicago, the subdivider shall install sewers in conformity with such plan, although a connection to an existing main may not be immediately practicable.
(8)
Storm sewer.
a.
In any subdivision of land hereafter made in that portion of the village lying west of Ridge Road, there shall be constructed a storm sewer system for and throughout the entire subdivision, which shall be separate and independent of the sanitary sewer system.

If at any time the village requires access to the easement for either new construction or maintenance of an existing utility, the property owner shall remove the encroachment and access to the easement shall be provided to the village, if in the opinion of the Village Engineer there is no other reasonable and cost effective method of accessing the utility. All costs associated with removing any encroachment in an easement shall be the responsibility of the property owner. Any costs that are incurred by the village for accessing the easement shall be repaid to the village within 30 days after notice is provided to the property owner by the village. The village will not replace or repair any removed or damaged encroachments located in an easement.
c.
A property owner may submit to the Director of Engineering and Public Works a request to allow for the placement of an otherwise restricted encroachment. Such a request shall include a plan, a statement of hardship, drawings and any other materials requested by the Director of Engineering and Public Works.
