As a condition of approval for the operation of the Puente Hills Landfill, a joint powers authority was formed pursuant to an agreement dated February 15, 1994, between Sanitation District No. 2, the County of Los Angeles, and the City of Whittier. The primary objective of the joint powers authority, the Puente Hills Habitat Preservation Authority (Habitat Authority), is to preserve and maintain native habitat in the region near the landfill.
The funding for the Habitat Authority comes from a $1.00 per ton of solid waste disposed fee assessed on users of the landfill. Over $64 million in funding has been provided to the Habitat Authority from 1994 through 2013. The landfill closed on October 31, 2013.
Beyond this date, the open space lands will continue to be preserved and managed in perpetuity using a management endowment that the Board of Directors has established.
