Rule, then engineered stormwater controls shall be used to control runoff from the first inch of rainfall; new residential and nonresidential development shall not exceed 30 percent builtupon area; (C) Land within the watershed shall be deemed compliant with the density requirements if the following condition is met: the density of all existing development at the time of reclassification does not exceed the density requirement when densities are averaged throughout the entire watershed area at the time of classification; (D) Cluster development shall be allowed on a projectbyproject basis as follows: (I) overall density of the project meets associated density or stormwater control requirements of this Rule; (II) buffers meet the minimum statewide water supply watershed protection requirements; (III) builtupon areas shall be designed and located to minimize stormwater runoff impact to the receiving waters, minimize concentrated stormwater flow, maximize the use of sheet flow through vegetated areas, and maximize the flow length through vegetated areas; (IV) areas of concentrated development shall be located in upland areas and away, to the maximum extent practicable, from surface waters and drainageways; (V) remainder of tract to remain in vegetated or natural state; (VI) area in the vegetated or natural state may be conveyed to a property owners association, a local government for preservation as a park or greenway, a conservation organization, or placed in a permanent conservation or farmland preservation easement; (VII) a maintenance agreement for
