1. Updating the Dearborn County Historic Structures Survey Margaret Minzner Dearborn County GIS March 14, 2007

2. Introduction The purpose of this project was to update the 1983 Interim Study of Historic sites and convert them to digital format

3. Presentation Discussion  Project History  Methodology  Results  Next Steps

4. Project Origin 1983 First Interim Report of Historic Sites from IDNR

5. Project History  2005 Future Land Use Plan created by Planning and Zoning  2005 GIS Data created using IDNR Quads with locations drawn from the study  2006 Education Grant awarded  2006-present Sites verified using existing data and field work

6. Scan, Georeference, Create Geodatabase  Obtained Interim Report from public library  Scanned and georeference Quad maps from IDNR  Geodatabese creation, digitize site location

7. Methodology

8. Preliminary Project Parameters  Include Unincorporated County Sites  Exclude Historic Districts  Outstanding = 74, Notable = 207, Contributing = 402

9. Verify with Address Data  Used Indiana Ortho for Dearborn County to verify structure  Assigned PIN and address data based on location

10. Verify with CAMA Data  Ensure that there is a potential historic structure at address

11. Collect photos  When possible photos were collected from Assessor’s Database

12. Field Work  Sites that were not consistent with address, parcel, or CAMA database were field checked and photos were taken  GPS point documented at location  Incorporated into the historic structures database

13. Results

14.  Changes since 1983 are evident › Some structures no longer exist › Some have changed status

15. Next Steps

16. Continuation of Field Work  Continue the update with historic districts  Add in structures that could be admitted since the 1983 survey  Develop a revised list

17. Education  Presenting findings to local groups  Online presentation of data

18. Conclusion

19. We should probably update the Historic Structures Inventory more frequently than every 24 years.
