House committee substitute to the 1st edition makes the following changes. Amends GS 143-214.7(b3) (pertaining to stormwater runoff rules) to specify that stormwater runoff rules and programs may require owners of private property that does not include small scale residential development to install new or increased stormwater controls when a preexisting development is redeveloped if the redevelopment will result in (1) land disturbance, as that term is defined under GS 113A-52(6), of more than 50% of the tract on which the redevelopment is to occur or (2) an increase of more than 50% of the impervious surface on the tract to be redeveloped.
