Fall Storms Bring Flooding to SE Virginia

The impact of four feet of flooding on Hampton Boulevard, the major N/S road in west Norfolk. This is one of two roads leading Naval Station Norfok.

Jose and Maria are messing with Southeast Virginia. The video above is Hampton Boulevard in Norfolk, VA during the run up to the high tides on September 19, 2017, from Jose. On Sept 26 and 27 another set of high tides is hitting. At least these "modest" floods help us find all the areas that flood so we can put them on the map.

We are also in the midst of a major regional, crowdsource flood mapping effort around the hugest projected tide on November 5, 2017, the so-called "King Tide" of the year. We've been holding mapping trainings leading up to that event.

During the Jose floods I was out in the water doing some mapping. The images below show a flooded residential neighborhood in Norfolk (left) and the flood mapping I did (right) using the Sea Level Rise phone app. Walking the edge of the flooded zone, I dropped GIS pins every 4-5 feet and got an outline of the flooding., showing the extent of the inundation. The data set can be exported as an .xls or .csv file and transformed into a shape form on a map and used to test inundation models. All of this helps us project where the water will come next time we get +4' of water.
