How Old Is Woodlake's Housing Stock?
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
Two dates define the high-risk tiers of residential plumbing from a lead standpoint: 1970, before which lead pipes were commonly installed for service connections, and 1986, before which lead solder was standard in copper plumbing. A median build year of 1988 places Woodlake's housing distribution well within that older risk zone. The bar chart above breaks down how much of the stock falls into each era - and the pre-1986 share alone represents more than half the residential inventory, making plumbing-era risk a defining characteristic of the local water safety picture.
Over half of homes in Woodlake were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Woodlake: Remediation Cost in Perspective
Within the Woodlake market, estimated remediation claims a small portion of typical property equity - the financial burden is proportionally low.
Remediation costs in Woodlake are relatively low compared to home values. The $1,200–$3,300 estimated range is a small fraction of median property value. Home values are 61% below the California average.
Protecting Children from Lead in Woodlake
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 59% of local housing was built before solder rules changed - as is the case in Woodlake - a faucet-level sample closes the gap that aggregate utility data cannot.

Historical Flood-Claim Evidence for Woodlake
Historical NFIP data for Woodlake contains 24 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $34,213. Among ZIP codes with claim records, 100% have an A- or V-family dominant rated zone recorded in those historical claims. This is not a complete current FEMA property-map inventory.
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. The <strong>$2,200</strong> remediation estimate shown here excludes flood insurance and is not derived from NFIP claim count.
Claim count does not establish current property risk. Check the exact address in FEMA's current map and obtain a property-specific insurance quote when relevant.
