Figure 7: Slope and Proposed Grading l M I The City has granular (i.e. highly -detailed) topographical mapping that uses one -foot contours, dating from 2017, which was used in the above mapping. As prescribed by the Southeast Hills adopted methodology, this granularity is "smoothed" by calculating the average slope over three-foot by three-foot areas. This approach is intended to balance being protective in that even small variations in slope using one -foot contour intervals are mapped but allow for the "noise" of minor variations in topography to be reduced by averaging out slopes over nine -square -foot areas. Lots and Grading Areas: Overlap with Areas of 25 Percent or Greater Slope Figures 8-12 are focused excerpts of the map in Figure 7. The images focus on various areas or anomalies (minor variations or `spots') within proposed lots and graded areas, where the slopes are 25 percent or greater over very small areas, generally within a much broader area that otherwise has slopes less than 25 percent. (Lots with larger or more significant areas of slopes, such as Lots 10, 11 and 19, are discussed separately, below). Staff conducted a field visit on March 12, 2019, where the applicant had flagged a number of these spots. It was difficult, in most instances (and in the absence of the flags) to distinguish significant differences in the slope of these small areas versus the surrounding areas less than P18-00781P18-00791P18-00801P18-0081/PUD-130 Planning Commission 10807, 11021, and 11033 Dublin Canyon Road and the parcel west of 11021 Dublin Canyon Road 14 of 26
