Housing & Infrastructure in Cottonwood
With 48% 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
Prohibited from residential plumbing since 1986, lead solder divides Cottonwood's housing stock along a timeline that the median build year of 1983 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 Cottonwood were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Cottonwood Homeowners
Low proportionality - that's the Cottonwood picture when remediation costs are placed against typical home equity.
Remediation costs in Cottonwood 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 52% below the California average.
Lead Exposure Risk for Children in Cottonwood
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 48% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Cottonwood.

Historical NFIP Claim Context in Cottonwood
Historical NFIP data for Cottonwood contains 10 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $35,518. 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.
