6. Deteriorated historic features will be
repaired rather than replaced. Where
the severity of deterioration requires
replacement of a distinctive feature,
the new feature will match the old in
design, color, texture, and, where
possible, materials. Replacement of
missing features will be substantiated
by documentary and physical
evidence.
