Housing Age Profile
The character of Pierre Part's housing stock is one of deep historical layering — a median build year of 1985 signals a city built largely before the plumbing era changes of 1986 and 1970. Lead-soldered copper joints and, in the oldest properties, lead service lines are commonly present in this inventory. That context shapes what individual water testing may reveal, particularly in neighborhoods where the oldest housing is concentrated.
Over half of homes in Pierre Part were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Pierre Part Homeowners
Looking at how documented remediation costs fit within Pierre Part property values, the equity share lands in the moderate tier — a finding that positions the household financial perspective between routine maintenance and a significant budget commitment, where most homeowners can successfully address documented issues by treating the expense as a planned financial priority rather than an unexpected one.
Remediation costs are moderate relative to home values in Pierre Part. The estimated $1,100–$2,600 range is manageable for most homeowners but still worth budgeting for. Home values are 5% below the Louisiana average.
Lead Exposure Risk for Children in Pierre Part
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 interior plumbing shapes the local picture: 55% of Pierre Part homes predate the federal solder ban, and aggregate sampling either approaches or crosses the action benchmark. That mix makes a single-home draw a standard pre-purchase or pre-occupancy step.

Flood & Climate Risk in Pierre Part
Substantially more flood exposure than most communities appears in Pierre Part's NFIP record — 563 documented claims and 100% of ZIP codes in FEMA flood zones. That exposure level makes the water-quality implications of flooding an active planning consideration rather than a background one.
Pierre Part has a significant flood history with 563 FEMA flood insurance claims on record, averaging $5,175 per claim. With 100% of ZIP codes in FEMA-designated flood zones, flood risk is a major concern for homeowners and water quality.
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>$1,700</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.
