Greenwood Infrastructure Age
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
Lead solder was allowed in new plumbing until the 1986 federal restrictions, which is why older homes in Greenwood deserve a closer look; the median build year is 1998.
Most homes in Greenwood were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Greenwood: NFIP Claim Records and Water-Quality Context
Historical NFIP data for Greenwood contains 44 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $37,639. Among ZIP codes with claim records, 0% 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 $1,100 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.
