How Old Is Knights Landing's Housing Stock?
With 66% 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
When a city's housing median build year is 1962, as in Knights Landing, the implication for water quality research is straightforward: municipal-level data captures what leaves the treatment plant, but household plumbing from before 1986 determines what actually arrives at the tap. In cities where older housing predominates, that gap between system-level and household-level data is widest.
Over half of homes in Knights Landing were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Knights Landing: Remediation Cost in Perspective
In Knights Landing, property wealth outpaces what documented remediation typically demands - the equity burden lands well within the low tier.

Protecting Children from Lead in Knights Landing
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 Knights Landing represents 66% of the inventory, and citywide monitoring runs at or above the federal action level - making an in-home read a standard household-level step.

Historical Flood-Claim Evidence for Knights Landing
Historical NFIP data for Knights Landing contains 6 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $10,921. 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>$1,200</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.
