How Old Is Mott's Housing Stock?
With 83% 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
Decades of residential development in Mott took place before the two main regulatory milestones that reduced plumbing-era lead risk: the phase-out of lead pipes before 1970, and the federal ban on lead solder in 1986. With a median build year of 1966, the housing stock here is anchored in that earlier period. The distinction between pre-1970 and 1970-to-1986 construction matters: the oldest homes may have lead pipes in the service line and lead solder in the copper joints, while the 1970-to-1986 tier still carries the solder risk even after lead pipes became less common. Together, these two risk layers affect a majority of the residential properties in the city — a fact the aggregate water quality data doesn't directly reveal.
Over half of homes in Mott were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Mott: Remediation Cost in Perspective
Remediation costs in Mott represent a substantial share of typical property values — the equity impact here is significant, and careful financial planning is essential rather than optional for most homeowners.
At 2.8% of home value, remediation costs in Mott represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $1,600–$3,300. Home values here are 51% below the North Dakota average.
Protecting Children from Lead in Mott
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.
Wherever 83% of local housing was built before solder rules changed — as is the case in Mott — a faucet-level sample closes the gap that aggregate utility data cannot.

Climate-Related Water Risk for Mott
Although Mott's flood history doesn't reach high-severity thresholds, NFIP data documents 92 claims and FEMA maps place 100% of ZIP codes in designated flood zones — a combined profile that makes flood-related water quality considerations a reasonable planning baseline.
Mott has a moderate flood history with 92 FEMA claims averaging $2,785 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>$2,400</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.
