If I do not have to comply with Attachment 4 then does my SWMP need to include a Post-Construction Storm Water Management in New Development and Redevelopment Program?
Yes, all Permittees must have a Post Construction Storm Water Management in New Development and Redevelopment. Those that must comply with Attachment 4 shall have a program that is at least as stringent as that contained in the Design Standards in Attachment 4. Those that do not have to comply with Attachment 4 are not required to use the Design Standards in their programs.
