Housing Age Profile
What does a median build year of 1998 mean for water safety in Grapeview? It means the housing stock straddles two key plumbing thresholds: the 1986 federal ban on lead solder in copper plumbing, and the pre-1970 era when lead pipes were commonly installed for service lines. A meaningful share of homes predates one or both of those cutoffs, creating varied risk levels across the city's housing inventory.
Most homes in Grapeview were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Grapeview

Remediation costs in Grapeview are relatively low compared to home values. The $800–$1,800 estimated range is a small fraction of median property value. Home values are 3% above the Washington average.
Grapeview: Lead Risk & Vulnerable Populations
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.
Wherever 44% of local housing was built before solder rules changed — as is the case in Grapeview — a faucet-level sample closes the gap that aggregate utility data cannot.

Grapeview: Flood History & Water Damage Risk
A moderate NFIP record for Grapeview — 1 insurance claim paired with 100% of ZIP codes in FEMA flood zones — points to a flood history where water-quality pathways have likely been periodically relevant.

How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies.
