In 2005, White was challenged for re-election by minor and perennial candidates and won re-election with 91 percent of the vote–the highest percentage received by a mayoral candidate in Houston in 60 years. During his second term, White focused his work on improving graduation rates in the city's high schools, enforcing air pollution standards, reducing the possibility of flooding in newer areas, adopted a more flexible system of working hours, and to create public-private initiatives with private business and community organizations to stimulate growth in the city's most neglected subdivisions. His moderate leanings were shown by his defense of businesses, such as Shawn Welling's Planet Funk, which faced closure in mid 2005. In 2005, White formed the Mayor’s Wellness Council and launched the Get Moving Houston fitness campaign. Houston had previously been rated “Fattest City in America" by Men’s Fitness magazine. In 2006, White proposed a series of eight city propositions aimed at improving infrastructure without a tax increase. All eight city propositions passed in a November 2006 election. White worked to create the Discovery Green park in Houston, which held its groundbreaking in October 2006. Mayor White's 2008 inauguration was held at the park. The park officially opened to the public in April 2008 with a ribbon cutting led by White. In 2007, the FBI released a report showing an increase in Houston's murder rate. While some speculated about the impact of Hurricane Katrina victims who settled on the Southwest side of town, Mayor White released a statement concerning the FBI's findings: "With the regard to the 2006 figures now being reported, the FBI calculated a murder rate per 100,000 people for Houston based on census estimates of a 2,073,729 population as of July 1, 2005. That was before Houston’s population swelled by well over 100,000 people. On the basis of U.S. Post Office change of address information we estimated the 2006 population at 2,198,755. While it is normally fair to make year-to-year comparisons based on population estimates that lag crimes by a year or more, the unusual increase in Houston’s population for 2006 makes our City’s figures for the murder rate per 100,000 not quite comparable to the rate in other communities in 2005." Energy conservation topped the Mayor's list of concerns in 2007. Via the City's Power to People Web site, Mayor White encourages energy conservation through tips and tools, education about tax incentives, and raffles. In
