Introduction:Historically significant places can be whole districts, landscapes, sites, buildings or structures, as long as they have significance to the history of a community, state, or the nation. All the historic properties mapped here meet the criteria to be nominated to the State and National Registers of Historic Places. Once listed on the Register, a site receives increased protection against future damage.

Methods:• July 2013 - Organize State Historic Preservation library according to

Tax Map Key.

• August 2013 - Separate all preservation plans from other archaeological reports in the SHPD library.

• Sept. 2013 – Dec. 2014 – Digitize preservation plans by extracting data from hardcopy reports and entering into a table.

• Jan. 2015 – present - Geoprocess preservation plan table by relating it to State GIS Tax Map Key shapefile. Create new feature class of TMK’s for which preservation plans have been written. Add different basemaps to create varying contexts in which to analyze historic properties.

Results & Discussion: By joining the SHPD spreadsheet to State GIS data for Tax Map Keys, I was not only able to map the preservation areas, but also find values for various <null> fields simply by searching the attribute tables and geoprocessing the feature classes in my geodatabase. The State data for TMK provides current landowner information; by adding an acres field and calculating geometry I would be able to add the total acreage of each parcel to the site descriptions; the University of Hawaii data provided historic land divisions for each TMK; and finally, using current Landsat data to zoom in on parcels could yield information regarding damage to sites.

Problem Statement:When a property is determined as historically significant, protective measures for the sites on the property are stipulated in a document called a preservation plan. The State Historic Preservation Division (SHPD) reviews these preservation plans and conducts follow-up site visits to check compliance with the measures outlined in the plan. To date, most of these properties have not received follow-up inspections. This project originated in 2013 as a simple spreadsheet to collect current landowner contact information, brief descriptions of sites, and preservation recommendations so that SHPD would be able to arrange informed inspections to check the condition of the sites. The project has since evolved into a geographic information system that stores and maps location data for historic properties on Maui. The preservation data in this GIS is based on published reports found in the SHPD library during the time of data collection. There are many more historic properties whose documentation must still be located and entered into this GIS.
