Research notes
State enabling for SHPO and the Louisiana Register of Historic Places. Federal conflict check enabled because the binding force in many cases is NHPA §106 via federal funding/permits — local historic-district designations have city-law force but the state-level overlay is the SHPO consultation gate. New Orleans hosts more National Register districts than any other Louisiana city; Garden District / Lower Garden District are the canonical examples cited in the task brief. Local commissions vary widely in regulatory strength — some are advisory, some have COA-approval authority.
