Avoiding Adverse Effects Under s. 106
•
Project Team will work to achieve a finding of “No Adverse
Effect” through the following efforts:

Commission, Cambridge Historical Commission, and
Boston Landmarks Commission throughout design and
construction process.
– Application of Secretary of the Interior Standards for
Rehabilitation:
• Preserve historic character;
• Avoid conjectural historical elements;
• Maintain distinctive materials, features, finishes and
construction techniques;
• Repair or replace elements with matching materials;
• Use gentlest possible chemical and physical treatments;
• Identify and preserve the relationship of
a property to its setting; and
• Preserve surrounding landscapes and visual
relationships with surrounding properties.
