56. How We Summarized Health Risks? Franklin County Public Health and Franklin Soil and Water Conservation District have created a ranked list of “Identified Areas of Concern.” The following metrics were used within a GIS to identify and rank these Areas of Concern. - Dry Weather Screening Results - Locations of HSTS - Population/Building Density

57. Dry Weather Screening Density Variable

58. Dry Weather Screening Density Variable - ENLARGEMENT -

59. Population / Building Density Variable

60. HSTS Density Variable

61. Summarizing Variables DWS Density HSTS Density Population / Housing Density Numerical values assigned to density layers. Typical for each layer produced 0 4 6 5 3 2 1

62. Highest Ranking Areas Extracted / Highlighted 3 Variables Summarized
