Neighbors to 414 Shepherd have reported basement flooding coming from the adjoining wall. They have hired a waterproofing company to look into the flooring and they have determined it is the underpinning from 414 Shepherd causing the damage.
DCRA has been to this property on several occasions, meeting with the [neighbors] on at least two occasions within the last week or so. We were at the site again today. Unfortunately we have yet to determine the precise cause of the water intrusion, although it has been witnessed. We are having the builder perform some additional protective measures in the hopes that the issue is resolved sooner rather than later. Specifically, we are having the builder install tarps over the incomplete portion of a new rear addition roof as well as having them dewater some ponding observed in the front of the property. The ponding is likely too far away from the point of water intrusion to be a contributing factor, but it is an issue nonetheless. The new, incomplete roof is a more probable source of the water intrusion, but that is a bit speculative at this point.
We have a special assistant assigned to the case, Steven Fall, in order to stay on top of the new protective measure installation and to enhance communication with the [neighbors].
Thanks to everyone for your assistance in this matter.
