The requirements for the grading and draining of building lots shall be as provided herein.
(A) The foundation walls of every dwelling house, and every other building having a basement under any part thereof, shall be constructed to an elevation at least four inches higher than the top of the abutting street, (measured at the mid-point of the lot frontage), plus a height equal to one-half inch for each foot of distance from such building to the abutting street curb. The finished grade of the ground from the front of such building to the street shall slope toward the street at the rate of not less than one- half inch to the foot, throughout all portions of the front yard.
(B) For a distance of at least ten feet from the other walls of such building, the ground shall slope away from the building at a grade of not less than six inches to the foot.
(C) Where it is not practicable to grade the lot so as to provide natural runoff of surface water from the entire lot to a street, storm sewer or other approved outlet, a drainage line or lines of field tile, vitrified tile or other nonporous pipe of acceptable size shall be installed, with proper inlets to drain any part of the lot which would otherwise collect and impound water. The materials and method of installation of such lines shall be determined by the Municipal Engineer. Such drainage lines shall lead into the street, storm sewer or other outlet approved by the Municipal Engineer.
(D) The lot grading and drainage herein required shall not thereafter be changed by any owner, occupant or other person in control of the premises in such a way as to diminish or impede the runoff of water from such lot, away from any building, toward the street, storm sewer or other approved outlet.
(E) The Municipal Engineer shall have the power to modify the foregoing provisions and to make additional or substituted requirements on hillside lots, corner lots and in other individual cases where, because of unusual topographic or other problems, the above requirements would not produce the results sought, or where other grading or drainage treatment would produce equal or better results.
(F) Where curbs and gutters have not been installed, or required, in the abutting street the foundation and lot grades shall be predicated upon the proposed grade of the abutting street as established by Council.
(G) Foundation sump pump drains are to be connected to an appropriate drainage outlet (the street, storm sewer or other outlet approved by the Municipal Engineer) to the satisfaction of the Municipal Engineer. Maintenance of the draingage connection is the responsibility of the property owner.
