After 10 years in the planning, the City of San Juan Capistrano began construction for the Los Rios Historic Park October, 2008. David Voltz Designs had approached Barbara Butler in 2006 to design a play structure that would complement the historic buildings and the park setting, while being sensitive to the surrounding neighborhood. The Los Rios district is the oldest residential neighborhood west of the Mississippi, starting with the establishment of the Mission in 1776. Currently in fabrication, the play structure installation is scheduled for March 2009 with the grand opening in May.
