   *Redeveloping of existing impervious surface.
-If the development is a mixture of new development and redevelopment, the redevelopment performance standards apply only to “redeveloped impervious” surfaces. New development performance standards apply to all other pervious and impervious surfaces.
+If the site is a mixture of new development and redevelopment, the redevelopment performance standards apply only to “redeveloped impervious” surfaces. New development performance standards apply to all other pervious and impervious surfaces. Removing existing impervious to maximize "redeveloped impervious" surfaces is acceptable when the surfaces generate similar pollutant loads.
-“Redeveloped impervious” is impervious surface defined in the post-development condition, up to the area of impervious surface present in the pre-development condition. Swapping pre-developed and post-developed impervious surfaces within the site to maximize the “redeveloped impervious” is acceptable when the land uses generate similar pollutant loads.
