Housing Age Profile

Over half of homes in Granite were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Granite: Remediation Cost in Perspective
While Granite homeowners face a manageable path to remediation, the equity share sits in the moderate tier - a signal that proactive budgeting matters more here than in lower-ratio markets.
Remediation costs are moderate relative to home values in Granite. The estimated $950–$2,400 range is manageable for most homeowners but still worth budgeting for. Home values are 18% below the Oklahoma average.
Protecting Children from Lead in Granite
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 75% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Granite.

Historical Flood-Claim Evidence for Granite
Historical NFIP data for Granite contains 3 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $17,630. 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 <strong>$1,500</strong> 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.
