GOAL - to conserve heritage values and extend the physical life
COMPONENTS - identify values and Character Defining Elements
INTERVENTION – what level?(preservation, rehabilitation, restoration)
APPLY – Standards & Guidelines

1. Conserve the heritage value of a historic place. Do not remove, replace, or substantially alter its intact or repairable character-defining elements. Do not move a part of a historic place if its current
location is a character-defining element.

character-defining elements in their own right. Hawks Avenue in Strathcona (1905 & 1924)Circa 1945

4 Recognize each historic place as physical record of its time, place and use. Do not create a false sense of historical
development by adding elements from other historic places or other properties or by combining features of the same property that
never coexisted.

6. Protect and, if necessary, stabilize a historic place until any subsequent intervention is undertaken. Protect and preserve archaeological resources in place. Where there is potential for disturbance of archaeological resources, take mitigation
measures to limit damage and loss of information.

means possible for any intervention. Respect heritage value when undertaking an intervention.

8. Maintain character-defining elements on an on-going basis. Repair character-defining elements by reinforcing their materials using recognized
conservation methods. Replace in kind any extensively deteriorated or missing parts of character-defining elements, where there are surviving prototypes.
