How Old Is Gretna's Housing Stock?
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
A median build year of 2004 in Gretna points to a housing stock where post-1986 construction is the norm. That matters because lead solder in plumbing - banned federally in 1986 - is a primary pathway by which older homes can elevate tap water lead above what enters the distribution system.
Most homes in Gretna were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Gretna: Remediation Cost in Perspective
In Gretna, documented water and safety issues can be addressed without making a meaningful dent in home equity - the financial proportionality here is favorable, and the commitment fits within standard property planning frameworks.
Remediation costs in Gretna are relatively low compared to home values. The $1,600–$3,300 estimated range is a small fraction of median property value. Home values are 113% above the Nebraska average.
Protecting Children from Lead in Gretna
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.
Where pre-rule stock represents a smaller fraction of the inventory - 20% across Gretna - the structural drivers of household exposure run thinner. Aggregate readings under the federal benchmark reinforce that picture, with one-home draws remaining the only direct measurement for a specific address.

Historical Flood-Claim Evidence for Gretna
Historical NFIP data for Gretna contains 76 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $21,697. 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>$2,400</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.

What You Can Do in Gretna
- Test your water at home. City-level data shows averages - your tap may differ. Lead testing is especially recommended given the area's lead levels.
- Install a certified water filter. Filters rated for Fecal Coliform can reduce the most common contaminant found in Gretna's water.
- Check your home's plumbing. Homes built before 1986 may have lead solder in pipes. A licensed plumber can assess your risk.
