107 <br />growing bodies absorb more lead, and young children often put their hands and other <br />objects in their mouths. Most children do not have any symptoms, even if a blood test <br />shows that they have an elevated blood lead level. If a child does have symptoms, the <br />symptoms may be mistaken for the flu or other illnesses. <br />Most of the housing stock in Santa Ana was built before 1979 and is presumed to contain <br />lead paint. The 2016-2020 CHAS data shows 7,825 low- and moderate-income renter <br />households with children under the age of six were living in housing constructed before <br />1980, and 2,905 owner-occupied households meet the same conditions. <br />Number of Children with Elevated Blood Levels of Lead <br />The State of California mandates lead screening for all children who participate in publicly <br />funded health programs. In California, screening typically occurs at ages one and two <br />years. A blood level of 10 µg/dL or higher was previously referred to as an “elevated blood <br />level (EBL).” However, as it is now recognized there is no safe level of lead, and adverse <br />effects occur at levels below 10 µg/dL, an “elevated” blood lead level is no longer defined <br />at a specific cut-off point. Of Orange County children under the age of six whose blood lead <br />level has been fully tested 1.46 percent have levels greater than 3.5 mcg/Dl. <br />Discussion <br />Preservation of the physical and functional integrity of existing housing units occupied by <br />low- and moderate-income households is a cost-effective way to invest limited resources <br />to retain existing housing units already affordable to low- and moderate-income <br />households in the community. Many different types of housing services are needed. As <br />required by HUD’s Lead Safe Housing Rule, the City’s housing rehabilitation programs will <br />include appropriate safety measures such as testing and abatement for projects involving <br />units constructed prior to 1978. <br />EXHIBIT 1
