OBTAINING DATA FOR A HIGHWAY IMPACT STUDY

STEPS USED FOR OBTAINING DATA FOR A RECENT STUDY OF HIGHWAY IMPACT IN WASHINGTON STATE SERVE TO ILLUSTRATE DATA COLLECTION PROBLEMS. THE STUDY WAS CONCERNED WITH RURAL LANDS AND THE ORIGINAL HYPOTHESIS WAS THAT THE IMPACT OF ROAD IMPROVEMENTS COULD BE MEASURED USING PROPERTY VALUE. FOR EACH OBSERVED PARCEL OF PROPERTY IT WAS DESIRED TO OBTAIN: (1) A MEASURE OF PROPERTY VALUES, (2) MEASUREMENTS OF THE LOCATION OF THE PROPERTY FROM SEVERAL REFERENCE PLACES, (3) MEASUREMENTS OF THE LOCATION OF THE PROPERTY IN TERMS OF THE QUALITY AND QUANTITY OF SERVICE ROADS, AND (4) MEASUREMENTS OF OTHER CHARACTERISTICS OF THE PROPERTY THAT MIGHT AFFECT PROPERTY VALUES. THESE MEASUREMENTS WERE ACHIEVED IN SIX STEPS: (1) LAND SALES RECORDS, (2) AN INTERVIEWER VISITED THE STUDY PARCELS TO DETERMINE THE SIZE OF THE PARCEL, THE TYPE OF LAND UTILIZATION, AND THE LOCATION OF THE PROPERTY IN RELATION TO THE TOWNS AND ROADS, (3) THE SIZE OF PARCEL INTERVIEW DATA WAS CHECKED AGAINST PUBLIC RECORDS AND THE PROPERTY VALUE WAS CONVERTED TO A UNIT BASE OF 1 ACRE, (4) A LAND CAPABILITY RATING OR RATINGS RELATING TO THE UTILITY OF THE LAND WERE ASSIGNED USING DATA FROM PUBLIC RECORDS, (5) LOCATION CHARACTERISTICS WERE ASSIGNED TO EACH PARCEL USING 4 OR 5 REFERENCE POINTS, DEPENDING ON WHETHER OR NOT THE PARCEL WAS USED IN FARMING, AND USING INFORMATION FROM THE INTERVIEWS, AND (6) MEASUREMENTS OF THE QUANTITY AND QUALITY OF ROAD SERVICE TO STUDY PARCELS WERE THEN MADE USING ROUTE DATA FROM THE INTERVIEWS.
