In 2035, the continued trend of housing unit densification is clearly seen. The most
housing-dense TAZs are concentrated in the centralized urban cores of Orange County,
along the commuter rail lines, and the future bus rapid transit and high frequency bus
routes (Figures 26 and 27).
In summary, from 2008 to 2035, the County is projected to add 139,907 housing units, an
increase of 13.5%. The projected evolution of the County is for housing unit growth and
housing unit density to increase throughout the County, with growth concentrated in the
traditional urban cores.
The majority of future residential developments on raw land are projected to occur in the
central cities of Irvine and Tustin, and the southern region encompassing Rancho Mission
Viejo in the unincorporated portion of the County east of San Clemente.
