I am attempting to perform a Service Area analysis and am getting unexpected results. I am running the analysis using the detailed polygon generation. My issue is that there are a significant number of holes being generated in the service area results. To test these anomolies, I've run a simple routing problem to verify whether or not these "holes" are routable. In each instance, the routing problem is solved without issue. In the screenshot below, you can see the hole in the service area analysis. The turquoise line is the result of a routing problem. It solved correctly and the cumulative time indicates the entire hole in the service are polygon should be green (<5min drive time.)
I'm sure there is a setting that I am missing, but I've tried everything I can think of. I'd prefer to not user the generalized polygon generation setting, as the results negated a few pockets of "hard to reach" streets.
Any thoughts would be greatly appreciated.
