Housing & Infrastructure in Fish Creek
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Prohibited from residential plumbing since 1986, lead solder divides Fish Creek's housing stock along a timeline that the median build year of 1997 straddles. A meaningful share of homes predates the ban — a configuration that places moderate aggregate pressure on plumbing-related lead risk, distributed unevenly across neighborhoods.
Most homes in Fish Creek were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Fish Creek Homeowners
When estimated remediation is placed alongside median property values in Fish Creek, the resulting ratio is low — a finding consistent with a household financial perspective where documented issues can be addressed without a meaningful impact on overall equity position, making this market one of the more favorable contexts for remediation planning.
Remediation costs in Fish Creek are relatively low compared to home values. The $2,000–$4,000 estimated range is a small fraction of median property value. Home values are 108% above the Wisconsin average.
Lead Exposure Risk for Children in Fish Creek
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 37% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Fish Creek.

Flood & Climate Risk in Fish Creek
Over the multi-decade span captured by FEMA's National Flood Insurance Program, Fish Creek has accumulated a relatively small number of flood claims. That history points to a community where flood exposure is present but contained — and where the pathways by which flooding can affect water quality (overwhelmed treatment plants, contaminated private wells, distribution backflow) remain low-probability events rather than recurring concerns.
Fish Creek has a relatively low flood history with 1 FEMA claims on record. While risk is limited, severe weather events can still impact water infrastructure.
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>$3,000</strong> remediation cost per household.

What You Can Do in Fish Creek
- 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.
- Install a certified water filter. An NSF-certified pitcher or under-sink filter removes most common contaminants.
- Check your home's plumbing. With 37% of homes built before 1986, lead solder is a real possibility.
- Review your water system's CCR. Your utility publishes an annual Consumer Confidence Report with detailed test results. Request it or find it online.
