Why Capitol Hill needs this specifically
Capitol Hill’s dense rowhouse and mansion lots are strong candidates for a soil barrier, since wood-to-soil contact has had over a century to develop.
Very old, architecturally ornate wood-and-brick construction makes Capitol Hill among the oldest housing stock in the curated 20-area set — exactly the kind of housing where routine inspection matters most.
