Grading & Drainage Permits

No person shall commence construction prior to obtaining the appropriate grading and drainage permit as defined. In order to preclude inappropriate phasing of developments to circumvent the intent of this ordinance, when a proposed development activity will occur on a lot or parcel of land that has contiguous lots or parcels of lands owned by the same property owner, then the criteria as defined in this division will be applied to the total land area compiled from aggregate ownership parcels.
