Definitions.
Common plan of development or salemeans a construction activity that is completed in separate stages, separate phases, or in combination with other construction activities. A common plan of development or sale is identified by the documentation for the construction project that identifies the scope of the project, and may include plats, blueprints, marketing plans, contracts, building permits, a public notice or hearing, zoning requests, or other similar documentation and activities.
Construction activitymeans any human activity that involves clearing, grading, excavation, or other placement, movement, removal, or disposal of soil, rock, or other earthen materials that:
(1) Disturbs equal to or greater than one (1) acre of total land area; or
(2) Disturbs less than one (1) acre of total land area but is part of a larger common plan of development or sale that will ultimately disturb equal to or greater than one (1) acre of area. (For example, construction of a single-family residence on one lot in a subdivision where the developer and all builders combined will disturb one acre or more).
Construction activity does not include routine maintenance that is performed to maintain the original line and grade, hydraulic capacity, or original purpose of the site (e.g., the routine grading of existing dirt roads, asphalt overlays of existing roads, the routine clearing of existing rights-of-way, and similar maintenance activities). |
