The average approval of $343,045 sits well above the median of $141,400, so a small number of large deals is pulling the mean up. The median is the better guide to what a typical borrower here actually gets. Only 6.8 percent of approvals run on real estate terms, so SBA credit here is mostly working capital and equipment rather than property acquisition.

What this page does not hold.

- No NFIP communities are listed for this county in the FEMA Community Status Book.
- Flood zone record counts are not held. The flood coverage export has not landed, so no count is shown rather than an estimated one.
- Traffic counts resolve in the platform, not in this dataset, so no AADT figure is printed here.
