It seems to be a week for $50 million donations. A day after the Moody Foundation donated that precise amount to the University of Texas College of Communication, Houston philanthropists Rich and Nancy Kinder announced plans to give $50 million to the Houston Parks Board for the Bayou Greenways 2020 Project, an ambitious plan to connect greenspaces along the city's bayous and create new parkland.

The donation, made through the Kinder Foundation, is the largest donation in the history of Houston’s park system and one of the largest grants to a public greenspace in the United States.

The Bayou Greenways 2020 Project will create 1,500 acres of parkland within the city and ultimately connect 150 miles of trails (80 new miles connected to 70 existing miles of trails) along nine Houston bayous including White Oak, Brays, Sims, Hunting, Halls, Greens and Buffalo bayous, as well as Cypress and Clear Creek.

The ambitious project is funded through a public-private partnership. The city of Houston is pitching in $100 million, which voters approved in a bond referendum last November. The Houston Parks Board has committed to raising a matching $115 million. In addition to the $50 million Kinder donation, $21 million has been committed by the Houston Endowment, The Wortham Foundation, The Fondren Foundation, the Brown Foundation, multiple federal agencies and individual donors.

The Houston Chronicle reports that the donation was contingent on Houston City Council approval to turn over maintenance of the park lands to a nonprofit group to ensure that they are adequately kept up. In last week's session, city council approved the agreement authorizing the Houston Parks Board to oversee maintenance of the bayou trails with public monies. Under the arrangement, the newspaper reports, the city will pay the park board up to $10 million a year for upkeep of the signature park system.

“Bayou Greenways 2020 will complete the 100-year-old vision of city planner Arthur Comey and many like-minded leaders who saw the potential benefits of integrating Houston’s waterways into our recreational system. I would like to thank the Kinders for their generosity and commitment to the future of Houston,” Mayor Annise Parker said in a statement.
