Housing & Infrastructure in Manzanita
With 42% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.

Housing Age Profile
Over the decades, Manzanita accumulated housing from multiple construction periods. The median build year of 1998 places the midpoint of that stock near the 1986 threshold when lead solder in plumbing became federally prohibited — leaving a sizable share of homes on each side of that safety line.
Most homes in Manzanita were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Manzanita Homeowners
Low proportionality — that's the Manzanita picture when remediation costs are placed against typical home equity.
Remediation costs in Manzanita are relatively low compared to home values. The $800–$1,800 estimated range is a small fraction of median property value. Home values are 74% above the Oregon average.
Lead Exposure Risk for Children in Manzanita
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.
If 42% of the Manzanita inventory comes from before the federal ban on lead-bearing solder — and if utility samples sit at or near 0.015 mg/L — the gap between citywide averages and one specific faucet becomes a practical concern rather than a theoretical one. That is why one-home reads exist as a separate measurement. A certified filter through retailer networks addresses confirmed exposure where it appears in a household.

Flood & Climate Risk in Manzanita
FEMA data shows 100% of Manzanita's ZIP codes mapped into designated flood zones, paired with an NFIP record of 3 claims. That footprint places local flood exposure in the range where it warrants attention without rising to high-severity planning territory.
Manzanita has a moderate flood history with 3 FEMA claims averaging $9,810 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>$1,200</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.
