Housing & Infrastructure in Cascade Locks
With 59% 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.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Heavily weighted toward older construction, Cascade Locks's housing stock carries a median build year of 1972. That profile puts a majority of homes in the era when lead-soldered copper plumbing was standard practice.
Over half of homes in Cascade Locks were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Cascade Locks Homeowners
Because property values in Cascade Locks comfortably exceed estimated remediation costs, the equity impact here is proportionally small.
Remediation costs in Cascade Locks are relatively low compared to home values. The $950–$3,200 estimated range is a small fraction of median property value. Home values are 17% below the Oregon average.
Lead Exposure Risk for Children in Cascade Locks
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.
When older housing represents 59% of the local inventory or aggregate readings approach the federal action level, an in-home check becomes the standard way to translate citywide averages into the specific reality of an individual Cascade Locks address.

Flood & Climate Risk in Cascade Locks
Over the multi-decade window covered by the National Flood Insurance Program, Cascade Locks has accumulated 2 claims — a total that suggests more than isolated flood exposure. With 100% of ZIP codes in designated flood zones, the water-quality implications of flooding move from hypothetical to periodically relevant: treatment intake can be compromised, wells can be infiltrated, and distribution backflow can occur.
Cascade Locks has a moderate flood history with 2 FEMA claims averaging $14,295 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>$1,900</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.
