Why Centennial Homes Need Downspouts Done Right
The Centennial area straddles the Portland–Gresham line with 1960s–80s subdivision housing that has hit replacement age almost uniformly. Streets here were built in single phases, which means original gutters fail in clusters — we often quote three houses on one street in the same month. Powell Butte's shadow brings localized heavy-rain cells that test every system's capacity a few times each winter.

Local drainage reality
Powell Butte's terrain wrings extra rain out of passing storms — capacity upgrades during replacement are usually worth the small increment here.
The problems we see most in Centennial:
- Phase-built neighborhoods failing on the same timeline street-by-street
- Localized downpours off Powell Butte overwhelming original systems
- Original 4-inch and early 5-inch gutters below modern capacity standards
What You Get — and What We Won't Overpromise
