The sidewalk running north/south along Bank Street on the east side of the building at 3333 M street is sinking several inches over a distance of at least 30 feet or so. It is likely due to water erosion and undermining. This is an extremely urgent emergency issue as another section of the sidewalk in front of 3333 M completely collapsed earlier in the year and this has the potential to do so as well. Please investigate.
