Housing & Infrastructure in Spokane
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.

Housing Age Profile
The story of Spokane's housing stock is one of layered development — neighborhoods built in different decades, each carrying the plumbing standards of their era. The median build year of 2007 reflects that layered character. Before 1986, lead solder was standard in copper plumbing; before 1970, lead pipes were commonly used for service lines. A substantial portion of the pre-1986 homes visible in the distribution above still carry the plumbing materials of those earlier standards — creating a risk environment that the city-wide aggregate water data doesn't fully capture.
Most homes in Spokane were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Spokane Homeowners
In Spokane, the equity impact of remediation is proportionally small — not the kind of financial commitment that rises to the level of a genuine planning constraint, but a minor share of what most properties here are worth.
Remediation costs in Spokane are relatively low compared to home values. The $800–$2,600 estimated range is a small fraction of median property value. Home values are 3% below the Missouri average.
Lead Exposure Risk for Children in Spokane
Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
Older stock in Spokane represents 36% of the inventory, and citywide monitoring runs at or above the federal action level — making an in-home read a standard household-level step.

Flood & Climate Risk in Spokane
Within the NFIP's national dataset, Spokane falls in moderate-exposure territory — 1 documented incident spanning multiple decades, with 100% of local ZIP codes sitting inside FEMA flood boundaries. That combination warrants inclusion in any thorough local water quality review.
Spokane has a moderate flood history with 1 FEMA claims averaging $4,479 per payout. 100% of ZIP codes fall within FEMA flood zones. Flood events can contaminate drinking water and overwhelm treatment systems.
How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies. Even after floodwaters recede, contamination can persist in wells and aging infrastructure. Flood damage can add significantly to the estimated <strong>$1,600</strong> remediation cost per household.
Residents in flood-prone areas should consider flood insurance even outside FEMA zones — over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.

What You Can Do in Spokane
- Test your water at home. City-level data shows averages — your tap may differ. NSF-certified test kits cost $20-40 and give results in days.
- Install a certified water filter. An NSF-certified pitcher or under-sink filter removes most common contaminants.
- Check your home's plumbing. With 36% of homes built before 1986, lead solder is a real possibility.
