Housing & Infrastructure in Collinsville

Housing Age Profile
Development in Collinsville unfolded across multiple decades, and the median build year of 1991 reflects a housing inventory where eras of construction are genuinely mixed - including portions that predate the federal prohibition on lead solder in plumbing.
Most homes in Collinsville were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Collinsville Homeowners
Placing remediation in the context of Collinsville's property market, the equity share is low - most homeowners here are weighing a financial commitment that fits comfortably within routine property planning, far from the threshold where remediation becomes a material equity decision rather than a standard upkeep consideration.
Remediation costs in Collinsville are relatively low compared to home values. The $1,350–$3,100 estimated range is a small fraction of median property value. Home values are 55% above the Oklahoma average.
Lead Exposure Risk for Children in Collinsville
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 the local data together points toward a structural gap that matters more here than in low-exposure communities. 34% of Collinsville stock comes from the pre-rule era, and citywide monitoring either approaches or sits beyond the federal benchmark under Lead and Copper Rule sampling. A baseline kit fits the routine-diligence category, with certified filtration available via retailer networks where confirmed faucet results warrant additional measures.

Historical NFIP Claim Context in Collinsville
Historical NFIP data for Collinsville contains 37 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $36,659. Among ZIP codes with claim records, 100% 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>$2,100</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.
