3 Oak View Community Oak View Community, City of Huntington Beach Orange County Hazardous Waste Collection Center Oak View by the Numbers CalEnviroScreen 3.0 score is 76-80% Average household size is 7 occupants. A dense, 1-square-mile neighborhood with a population over 10,000. The crime rate is 200% that of Orange County. 70% of those 25 or older lack a high school diploma or GED. 97% of students qualify for free or reduced-price lunch. Only 48% of those 16 and over are employed. Per capita income in Oak View is $16,700 vs. $31,400 for Orange County. Business Park School / Library Facilities: 1 primary school, 1 library, 1 community youth center, 1 small park and 2-3 community-based non-profits Residential Multifamily Advanced Power and Energy Program /20
