Cal. Pub. Res. Code § 30169
(f) The commission, through its executive director, shall enter into a binding and enforceable agreement with Aliso Viejo Company, and the agreement shall be recorded as a covenant to run with the land with no prior liens other than tax and assessment liens restricting the Aliso Viejo Planned Community. The agreement shall provide for all of the following:
(1) The Aliso Viejo Company shall provide at least 1,000 units of for-sale housing to moderate-income persons at prices affordable to a range of households earning from 81 to 120 percent of the median income for Orange County as adjusted for family size pursuant to the commission’s housing guidelines on affordable housing dated January 22, 1980, and July 16, 1979, and any additional provisions as agreed to between the commission and the Aliso Viejo Company as referred to in this subdivision.
For purposes of this subdivision, median income constitutes the figure most recently established by the Department of Housing and Urban Development at the time the public report for the units, or any portion thereof, is issued by the Bureau of Real Estate. The affordable units required by this subdivision shall be priced equally over the moderate-income range and shall reflect a reasonable mix as to size and number of bedrooms.
(5) This agreement may only be amended upon the determination of the Aliso Viejo Company or its successors or assigns, the commission, the Department of Housing and Community Development, and the County of Orange that the change is necessary in order to prevent adverse effects on the supply of low- and moderate-income housing opportunities and to improve the methods of providing the housing at continually affordable prices.
The Legislature hereby finds and declares that, because the Aliso Viejo Company, in addition to the 1,000 units of controlled housing provided in this subdivision, will provide for 2,000 units of subsidized affordable housing for low-income persons and 2,000 affordable housing units for moderate-income persons pursuant to the company’s housing program, the purposes of Section 30213 will be met by enactment of this subdivision. The Legislature further finds and declares that the general provisions of this subdivision are specifically described and set forth in letters by Aliso Viejo Company and the executive director of the commission published in the Journals of the Senate and the Assembly of the 1979–80 Regular Session, and it is the intent of the Legislature that the commission and Aliso Viejo Company conform the agreement provided in this subdivision to the specific provisions described in the letters.
