In 2002, Casa Pueblo wrote and presented a bill of law for the development and conservation of the Green Infrastructure for Puerto Rico.  After an intense communitarian community-based campaign, the law was approved by Legislature in September 2003.

Law 268 had an initial allocation of $20 million with subsequent allotments of around $5 million annually for the protection of sensitive areas in the country Law 268 assigns $20 million dollars initially and a recurring entry of $5 million dollars annually from the Department of Environmental and Natural Resources. The goal of this community strategy is to double the percentage of protected areas in Puerto Rico from 5% to 10%.  The law promotes acquiring lands with high ecological value to increase the island’s protected areas from a 5% to a 10%.

In 2004, Casa Pueblo cooperateds with the Department of Environmental and Natural Resources in evaluating ons for two highly sensitive areas in the La Olimpia sector and in Adjuntas, and subsequently acquired themthe lands.
