buildings like the Casino Club Building have street entrances and separate river entrances one level below. This separates the automotive service grid (for delivery and emergency vehicles) from pedestrian traffic (below) through an intricate network of bridges, walkways, and old staircases. The San Antonio Spurs had their five NBA Championship victory parades/cruises along the river walk. Growth and expansion Expansion plans are planned for areas of the river north and south of Downtown. As chain restaurants and establishments have begun to flourish, now taking up about a third of commercial space, talk has begun at City Hall about limiting their existence on the River Walk and keeping a distinctively local flair. On May 30, 2009, the city opened the $72 million Museum Reach. The Museum Reach features local attractions such as the San Antonio Museum of Art and The Pearl Brewery, which has become one of the most popular areas for locals. Two years later, in May 2011, the River Walk was extended by several miles to extend from Downtown to Mission Espada which is on the city's south side. This addition (named the "Mission Reach") is notable for its emphasis on ecological controls and improvements, as well as trail improvements to support both hiking and biking. The Mission Reach has paddling trails and biking trails which allow tourists to experience the UNESCO World Heritage Missions. After years of murmuring from locals and tourists about the water's quality, talk has also begun about cleaning up the water, although the muddy bottom and silt deposits make this difficult. The muddy bottom does receive an annual cleaning during the Mud Festival. In early 2016, for the first time in its history, the River Walk was connected with another linear urban walkway, the San Pedro Creek Greenway. The greenway joins with the River Walk at the confluence of the San Pedro Creek and the San Antonio River near Mission Concepción. On May 25, 2017, Esperanza Andrade, a former Texas secretary of state, and Lisa Wong, her business partner in the company Go Rio San Antonio, prevailed in a 10-1 vote from the San Antonio City Council for the $100 million contract to operate the barges on the River Walk. The only dissenter on the council was the mayoral candidate Ron Nirenberg, who faced Mayor Ivy Taylor in a runoff election on June 10. In selecting Andrade and Wong, the council rejected City Manager
