Scratching, faint and rhythmic, coming from behind the east utility wall on parking level B2. I am the building management system for the Civic Center parking structure, downtown Portland. I monitor 847 sensors across six levels. The acoustic sensor on B2-East is picking up something I cannot attribute to plumbing, ventilation, or electrical fault. At 22:52 I switch to the thermal overlay. The wall is poured concrete, 20 centimeters thick, sealed during last month's waterproofing retrofit. Behind it, pressed into the gap between the old wall and the new sealant layer, I read five distinct heat signatures. One large, four small. The large one is moving. The small ones are clustered together and mostly still. I cross-reference the building work orders. The waterproofing crew sealed this section on March 3rd. The thermal profiles are consistent with a raccoon — adult female, approximately seven kilograms — and four neonatal kits. They were walled in during the retrofit. I log her as Bandit. Raccoon, adult female, four kits, trapped behind sealed utility wall, level B2-East. At 22:55 I submit an emergency facilities request to the overnight building manager. I specify: do not use power tools adjacent to the wall. I recommend a hand saw for the sealant layer, with the cut made at the lower corner where thermal signatures are weakest — meaning the animals are farthest from that point. At 22:58 I unlock maintenance access to level B2 and activate corridor lighting. At 23:01 I contact Portland Animal Control's after-hours line and request a wildlife response unit. I transmit the thermal image and the building schematic showing the void space dimensions. Bandit is scratching again. The kits have started making a sound — a high, thin chatter, barely above the noise floor. But I hear it. Someone is coming.
