Housing Age Profile

Prohibited from residential plumbing since 1986, lead solder divides Bryan's housing stock along a timeline that the median build year of 1994 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.

Pre-1970 (Lead Pipes Risk)

Pre-1970 (10%) 1970–1986 (31%) Post-1986 (59%)

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

Cost Context: What Remediation Means for Bryan Homeowners

When remediation costs are measured against Bryan home values, the resulting ratio is in the low tier - addressing documented water and safety issues here claims only a minor fraction of typical equity, and most homeowners are in a position where the financial commitment is straightforward rather than a material burden on their household budget.

Median Home Value

$237,600

Est. Remediation

$1,500

Remediation as % of home value 0.6%

Remediation costs in Bryan are relatively low compared to home values. The $986–$2,243 estimated range is a small fraction of median property value. Home values are 4% above the Texas average.

Lead Exposure Risk for Children in Bryan

41%

Homes Built Before 1986

0.0033

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.

Pulling a tap sample fills the gap that utility data cannot close, particularly here where 41% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Bryan.

Historical NFIP Claim Context in Bryan

Avg Reported Sum With Payment Data

71%

A/V Share of Claim-Record ZIPs

Historical NFIP data for Bryan contains 341 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $22,358. Among ZIP codes with claim records, 71% 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.
