How Old Is Angelus Oaks's Housing Stock?
With 66% 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
Because the majority of Angelus Oaks's housing predates 1986, when lead solder was banned from new plumbing, the median build year of 1972 reflects a city where lead-era plumbing materials are common rather than exceptional.
Over half of homes in Angelus Oaks were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Angelus Oaks: Remediation Cost in Perspective
At current valuations, Angelus Oaks sits in the low remediation-share tier — the equity impact of fixing documented issues is proportionally minor.

Protecting Children from Lead in Angelus Oaks
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.
Even where utility-side monitoring meets Lead and Copper Rule requirements, the 66% pre-rule share in Angelus Oaks keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.
