From Assessment to Treatment: Determining Integrity & Applying the Standards

Two critical concepts in historic preservation are assessment of historic integrity and application of the Secretary of the Interior’s Standards for treatment of historic resources.  This day-long workshop will cover the fundamental concepts of integrity used in the evaluation of historic resources and examine local, state and national thresholds for determining integrity. Instructors will examine how the condition of resources affects integrity – from assessment of an individual resource to a district assessment. The second half of the session will cover the application of the Secretary of the Interior’s Standards with case studies covering the topics of reversibility, contextual infill, compatible alterations and additions. The day will close with a tour of Ventura’s turn-of the century sites to assess integrity and the Standards covered in the lecture.

Learning Objectives

  1. Differentiate between projects that meet the standards and those that fail to comply
  2. Engage with creative methods for meeting the standards using solutions from case examples
  3. Examine the seven aspects of integrity and their relationship to historic significance
  4. Develop guidelines for evaluating integrity with modern resources
