Restoration help in Tigard

Tigard grew up in the sixties through the eighties, and the built map reads that way: subdivision after subdivision on ground that ranges from the Fanno Creek floodplain to the Bull Mountain slopes. The creek is the name to know. Fanno Creek floods its corridor regularly enough that Tigard has dealt with it as a planning fact for decades.
The buildings
Midcentury and later subdivision homes, mostly on crawlspaces, with newer builds on the slopes above. Crawlspace moisture is the chronic call; creek-corridor flooding is the acute one. The slope neighborhoods toward Bull Mountain add the hillside drainage pattern.
The water
Fanno Creek and its tributaries define the flood risk, and the low neighborhoods along the corridor know it. Away from the creek the calls run crawlspace damp, appliance failures, and the plumbing of houses now fifty-plus years old.
The callback
The split the crew asks about is creek-adjacent or not, and crawlspace or slab. A flooded crawlspace near Fanno Creek in January and a supply break in a Bull Mountain kitchen are both familiar jobs.
Coverage
The Fanno Creek corridor, the established subdivisions, Summerlake and the Bull Mountain slopes, and the southern edges.
