Housing & Infrastructure in Broussard
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
Cities with large shares of pre-1986 housing carry elevated aggregate risk from lead-soldered plumbing; Broussard sits on the lower end of that spectrum. The median build year of 1990 reflects a housing stock in which post-ban construction is dominant — meaning lead-soldered copper joints are less prevalent across the city as a whole. Still, aggregate figures don't tell you what's happening inside a specific older home. Any structure built before 1986, and particularly those built before 1970 when lead pipes were commonly installed, can still present meaningful lead risk regardless of the city-wide picture.
Most homes in Broussard were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Broussard Homeowners
In Broussard, 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 Broussard are relatively low compared to home values. The $1,200–$2,500 estimated range is a small fraction of median property value. Home values are 69% above the Louisiana average.
Lead Exposure Risk for Children in Broussard
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.
Reading aggregate data alone gives a clean picture for Broussard — system samples below the federal action mark and 29% pre-rule housing — yet that math averages many service connections. A one-tap draw gives the only direct read for a specific home.

Flood & Climate Risk in Broussard
Broussard's flood exposure sits in the moderate range: 391 NFIP claims on record and 100% of ZIP codes within FEMA-designated flood zones. Residents with private wells or older infrastructure have reasonable grounds to factor flood timing into their water quality awareness.
Broussard has a moderate flood history with 391 FEMA claims averaging $33,161 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>$1,800</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.
