3. NCHRP 25-25, Task 110 Research Objective Have agencies used the model in NCHRP Report 723? How do we know what’s working? What successes have DOTs and SHPOs had regarding post-World War II housing survey and evaluation? Synthesize specific approaches DOTs have implemented to identify and evaluate the historic significance of post-World War housing since the 2012 release of NCHRP Report 723, A Model for Identifying and Evaluating the Historic Significance of Post-World War II Housing.

4. A Model for Identifying and Evaluating the Historic Significance of Post-World War Housing Develop a practical, consistent, efficient, and useful approach to the identification and evaluation of post-World War II resources. Key Sections: • Survey Methodology • National Historic Context • Model Context Outline and Model Where are we today? NCHRP Report 723:

7. State of Practice In-Depth Survey Sample Communities Case Studies Purpose Identify all state DOTs and SHPOs that have developed or are in the process of developing a post-World War II housing survey and evaluation program Methodology Literature Review Screening Survey Purpose and Methodology State of Practice Survey

8. State of Practice In-Depth Survey Sample Communities Case Studies Screening survey sent to both DOTs and SHPOs. Twenty-nine out of 50 states responded. Six states submitted responses from both agencies. Results State of Practice Survey

9. State of Practice In-Depth Survey Sample Communities Case Studies State of Practice Survey Results: Awareness and Use of NCHRP Report 723 Awareness of NCHRP Report 723 Use of NCHRP Report 723 Model

10. State of Practice In-Depth Survey Sample Communities Case Studies Post-World War II Areas of Concern Suburban Developments Rural Residences In-Fill Housing Results: Resources of Concern State of Practice Survey

11. State of Practice In-Depth Survey Sample Communities Case Studies State of Practice Survey Results: Post-World War II Methodologies

12. State of Practice In-Depth Survey Sample Communities Case Studies Methodology In-Depth Questionnaire Sent to 17 agencies (12 DOTs and 5 SHPOs) Questions NCHRP Awareness and Use Established Approaches and Methodologies • Funding Sources • Who Initiated Development • Alternative Survey and Evaluation • Collaboration • Obstacles and Successes In-Depth Survey

13. State of Practice In-Depth Survey Sample Communities Case Studies In-Depth Survey Results Seven DOTs and three SHPOs responded Nationwide Historic Context most useful to agencies, followed by Survey Methodology Some difficulties in adopting survey methodology from NCHRP Report 723 Funding sources varied

14. State of Practice In-Depth Survey Sample Communities Case Studies Digging Deeper Additional Insight into Post-World War II Approaches Why did agencies develop approaches? How much collaboration with other agencies was involved? How was the initiative funded? Did all agencies accept the resulting approaches? How much was NCHRP Report 723 used in the development of the approach? Case Studies

15. State of Practice In-Depth Survey Sample Communities Case Studies Results Late 2000s when most SHPOs/DOTs began to grapple with post-war housing Widely Varying Funding Sources Collaboration between DOTs and SHPOs Ensures Success Good historic context is backbone of an effective post-war program. “To Each His Own” Case Studies

NCHRP 25-25 Task 110 Conclusion For More Information Visit the Project Website: http://apps.trb.org/cmsfeed/TRBNetProjectDisplay.asp?ProjectID=4334 The National Cooperative Highway Research Program (NCHRP) produces ready-to-implement solutions to the challenges facing transportation professionals. NCHRP is sponsored by the individual state departments of transportation of the American Association of State Highway and Transportation Officials (AASHTO), in cooperation with the Federal Highway Administration (FHWA). NCHRP is administered by the Transportation Research Board (TRB), part of the National Academies of Sciences, Engineering, and Medicine.  Any opinions and conclusions expressed or implied in resulting research products are those of the individuals and organizations who performed the research and are not necessarily those of TRB; the National Academies of Sciences, Engineering, and Medicine; or NCHRP sponsors.
