(A) Design criteria.
(1) Minimum lot dimensions in subdivisions designed for single-family detached dwelling developments shall be as indicated in the Zoning Ordinance.
(2) Acute-angled lot corners shall be minimized. In general, lots should be as nearly rectangular in shape as practicable with minimum rear lot widths of 30 feet.
(3) All lots, except those in planned developments, shall abut on a publicly dedicated street.
(4) Side lines of lot shall be at right angles or radius to the street line, or substantially so.
(5) Double-frontage lots are not permitted except:
(a) When lots back upon an arterial street.
(b) When topographic or other conditions render subdividing otherwise unreasonable.
(c) Any double-frontage lots shall have an additional depth of at least 20 feet to allow space for a buffer along the lot line bordering the arterial street.
(6) Lots abutting upon a watercourse, drainage way, channel, or stream shall have an additional depth or width, as required, to assure that a building area of at least 7,000 square feet is not subject to flooding.
(7) A shade tree, minimum 2-inch diameter, shall be planted within the front yard of all new single-family lots prior to occupancy. Tree species shall be selected from the village's approved tree list. The Planning and Zoning Coordinator may authorize alternative tree species and may issue a temporary occupancy permit if seasonal conditions prevent tree planting at the time of initial occupancy.
(B) Lot grading.
(1) Grading of lots and roadways within the village shall be accomplished in a manner to prevent ponding and shall not result in the flooding of any primary structures. The only exceptions are for stormwater detention/retention basins.
(2) Except in special cases, grading of all grassed areas of lots shall be kept within the range of 0.5% and 5%.
(3) Driveway grades on all lots, as measured from the top of curb to finished garage floor, shall be kept within the range of 4% and 8%.
(4) Drainage easements will be provided along the rear and/or side lot lines when surface waters from more than 1 lot are conveyed down a lot line.
(5) When the slope between adjacent lots is 3 foot horizontal to 1 foot vertical or greater, retaining walls or other improvements approved by the Village Engineer shall be required.
(6) A minimum of 4 inches of topsoil shall be provided on all lots and parkways.
(7) Parkways shall be sodded or seeded with Class I seed at the rate and method as indicated in, Section 642, of the Standard Specifications for Road and Bridge Construction, of the Illinois Department of Transportation.
(C) Addressing of lots, buildings, or structures.
(1) Numbering system. All lots, buildings, and structures in the village shall be numbered by the Zoning Administrator of the village.
(2) Location. It shall be the duty of the owner and occupant of every commercial, residential or industrial structure in the village to have placed thereon numerals showing the number of the dwelling.
(a) These numerals shall be clearly visible from the street. At least 4 inches in height and not greater than 8 inches in height and in a contrasting color visible from the street. The numerals shall be made of a solid material that is physically distinct from the underlying or surrounding surface of the structure to which they shall be attached (i.e., painted numerals and the like shall be prohibited).
(b) These numerals shall be placed at a location near the main entrance of the principal building.
(c) On corner lots, numerals shall be visible from the street on which the main entrance is located.
(3) Penalty. Any person, firm, or corporation failing to so number any structure owned or occupied by him or her within 10 calendar days after receiving notice to do so from the village shall be fined $10 for each day on which the failure to number continues.
