Hockley Infrastructure Age
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
The median home in Hockley was built in 2002, after the federal ban on lead solder in plumbing. Most of the housing stock postdates that cutoff, placing typical plumbing risk on the lower end — though any home built before 1986 still warrants individual testing.
Most homes in Hockley were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Hockley
In Hockley, 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.
Remediation costs in Hockley 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 30% above the Texas average.
Hockley: Lead Risk & Vulnerable Populations
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 Hockley averages stay clean and the pre-rule housing share holds at 19%.

Hockley: Flood History & Water Damage Risk
100% of ZIP codes in Hockley are mapped into FEMA-designated flood zones, and the NFIP records 342 claims reflecting a multi-event flood history. That combination places local flood exposure in the range where water-quality implications deserve at least periodic attention.
Hockley has a moderate flood history with 342 FEMA claims averaging $42,449 per payout. 100% of ZIP codes fall within FEMA flood zones. Flood events can contaminate drinking water and overwhelm treatment systems.
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>$2,100</strong> remediation cost per household.
Residents in flood-prone areas should consider flood insurance even outside FEMA zones — over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.
