How Old Is Lyon Mountain's Housing Stock?
With 77% 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.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Lyon Mountain's housing stock is predominantly older, with a median build year of 1948 that reflects decades of construction before federal plumbing standards were tightened. The 1986 ban on lead solder and the pre-1970 era of lead service lines are both relevant benchmarks here — a significant share of the residential inventory predates one or both of those cutoffs, creating an elevated baseline for plumbing-related lead risk that aggregate water quality data may not fully reflect at the household level.
Over half of homes in Lyon Mountain were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Lyon Mountain: Remediation Cost in Perspective
In Lyon Mountain, property values comfortably outpace what documented remediation typically costs — the equity share is proportionally low.
Remediation costs in Lyon Mountain are relatively low compared to home values. The $400–$1,300 estimated range is a small fraction of median property value. Home values are 56% below the New York average.
Protecting Children from Lead in Lyon Mountain
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.
Pulling a tap sample fills the gap that utility data cannot close, particularly here where 77% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Lyon Mountain.

Climate-Related Water Risk for Lyon Mountain
Flood exposure in Lyon Mountain is meaningful by NFIP measures — 2 claims on record and 50% of ZIP codes carrying FEMA flood zone designations. That level of activity makes flood history a relevant factor when evaluating local water quality over time.
Lyon Mountain has a moderate flood history with 2 FEMA claims averaging $19,595 per payout. 50% 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>$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.
