Another important red field characteristic is the slope of the site. This criteria helps identify red fields that are more economically viable for transformation to parkland and green space. The criteria for sites having a “not steep” slope was an average slope of 15% or less across the site. This condition would result in a slope value of 1 in the GIS model (Figures 6–8 to 6–10). This designation was established on the grounds that slopes greater than 15% are often considered to be steep by municipalities, and this would affect the types of development that are determined to be feasible (Leigh Valley Planning Commission 2008, Rubenstein 1996). According to Rubenstein (1996), slopes greater than 15% are considered “precautionary” and significantly limit programming. The slope of each parcel was established using GIS data obtained from the City of Los Angeles Department of Watershed Protection Agency (2011). Although slope did vary among sites, all red fields in all three neighborhoods were found to have an average slope of less than 15%.
