Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.

Housing Age Profile

Post-1986 construction is where the lower lead-solder risk lives, because that's when the federal ban on lead solder in plumbing took effect. In Parker, where the median build year is 2000, the housing stock falls broadly on the newer side of that threshold - a distribution that moderates aggregate plumbing-era risk compared to older housing markets.

Most homes in Parker were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Parker Homeowners

In Parker, the equity impact of remediation is proportionally small - not the kind of financial commitment that rises to the level of a genuine planning constraint, but a minor share of what most properties here are worth.

Median Home Value
$679,800
Est. Remediation
$3,000
Remediation as % of home value 0.4%

Remediation costs in Parker are relatively low compared to home values. The $2,000–$4,100 estimated range is a small fraction of median property value. Home values are 50% above the Colorado average.

Lead Exposure Risk for Children in Parker

18%
Homes Built Before 1986
0.0037
mg/L Avg Lead (Limit: 0.015)

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.

Confirming what flows from a specific faucet still requires a one-home draw, even where Parker averages stay clean and the pre-rule housing share holds at 18%.

Historical NFIP Claim Context in Parker

Avg Reported Sum With Payment Data

A/V Share of Claim-Record ZIPs

Historical NFIP data for Parker contains 22 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $10,546. 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>$3,000</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.

What You Can Do in Parker

  1. Test your water at home. City-level data shows averages - your tap may differ. NSF-certified test kits cost $20-40 and give results in days.
  2. Install a certified water filter. Filters rated for Stage 1 DBP Rule can reduce the most common contaminant found in Parker's water.
  3. Check your home's plumbing. Homes built before 1986 may have lead solder in pipes. A licensed plumber can assess your risk.
  4. Review your water system's CCR. Your utility publishes an annual Consumer Confidence Report with detailed test results. Request it or find it online.
