The Town Branch Neighborhood is the smallest rectangle on that map. Enlarge the chart to read it.
Our neighborhood is a small hotspot for groundwater recharge and you can see how the wetland with springs and depressed land coincides with the karst coloring when you click and blow up the map.
Although the Nature Conservancy guys who created it admit that more ontheground investigation (and underground) to confirm a stricter scientific map is needed, it matches what I have believed about our neighborhood for some time. You can see the national cemetery circle with the karst just to the north along the old alley between Gov ave and Hill ave and pinnacle and wpwp are bright as is my own yard!
Please note one particular error. Cato Springs Branch, a northeast-flowing tributary of the Town Branch, is mistakenly called the Town Branch on the map. The oldest available government maps mark the portion of the Town Branch that flows from the UA and through our neighborhood as the Town Branch.
This is a significant tool for working on green-infrastructure plans and the FNHA already has it but in PDFs, which I can't post on the blogs.
