1 APPENDIX A: Performance Curve Study Sites Geographic coordinates of select sites not included due to requests from restoration practitioners or land managers. (*) indicates sites where, due to limited project information, restoration year was estimated as the Clean Water Act 404 permit year. ( ) indicates high-performing sites used for curve development.
