Cost Context: What Remediation Means for Ravia Homeowners
Across Ravia, the equity share taken up by estimated remediation is small — a favorable ratio for most property owners.

Lead Exposure Risk for Children in Ravia
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.
When older housing represents 64% of the local inventory or aggregate readings approach the federal action level, an in-home check becomes the standard way to translate citywide averages into the specific reality of an individual Ravia address.
