(A) General Requirement: No person may fill, store or dispose of earth materials; alter an existing land grade, contour or drainage pattern; or perform any other land disturbing activity without first obtaining a grading permit pursuant to this section.
(B) Specific Projects Requiring A Permit: Projects that require a grading permit include, but are not limited to:
1. Construction of new homes or buildings;
2. Construction of new garages or auxiliary structures with a footprint of four hundred (400) square feet or more;
3. Installation of inground swimming pools;
4. Construction of an addition to an existing structure that adds four hundred (400) square feet or more to the existing structure's footprint;
5. Landscaping that changes the grade of the site such that existing drainage flows will be altered;
6. Any construction or landscaping activity which adds ten percent (10%) or more to the impervious surfaces of a lot (for purposes of calculating the impervious surfaces, semipervious surfaces shall be counted as impervious based upon a proportional contribution to runoff as determined by generally accepted engineering practices and standards);
7. Land disturbing activity proposed in a floodplain as established by the federal emergency management agency (FEMA);
8. Any land disturbing activity over an area greater than or equal to one acre; and
9. Demolition of any building or structure.
(C) Exemptions: Projects that, in the determination of the village engineer, do not alter an existing grade, contour or drainage flow will not be subject to the permitting requirements herein, including, but not limited to, the following:
1. Raised decks which do not significantly decrease infiltration;
2. Fences;
3. Tree removal and planting;
4. Replacement of garages or auxiliary buildings with structures of the same footprint and at the same locat
(D) Stormwater Storage: For all projects exceeding 400 square feet in area which also result in 250 square feet of net increase of impervious surface, a stormwater storage system must be installed that effectively captures 1" of water per square foot of new impervious surface. The runoff from the new impervious surface should be directed to the storage. (Ord. 2514, 12-20-2004; amd. Ord. 4038, 12-1-2022)
