in 1915. In late 1915, Weeghman's Federal League folded. The resourceful Weeghman formed a syndicate including the chewing gum manufacturer William Wrigley Jr. to buy the Chicago Cubs from Charles P. Taft for about $500,000. Weeghman immediately moved the Cubs from the dilapidated West Side Grounds to his two-year-old park. In 1918, Wrigley acquired the controlling interest in the club. In November 1926, he renamed the park Wrigley Field. In 1927, an upper deck was added, and in 1937, Bill Veeck, the son of the club president, planted ivy vines against the outfield walls after seeing the ivy planted at Perry Stadium, Indianapolis. Renovation The Ricketts family aggressively pursued a Wrigley Field renovation since buying the team and the stadium in 2009. During the annual Cubs Convention in January 2013, the family revealed the 1060 Project, which called for a $575-million, privately funded rehabilitation of the stadium to be completed over the course of five years. The proposal was vast and included planned improvements to, among other things, the stadium's façade, infrastructure, restrooms, concourses, suites, press box, moving the bullpens and clubhouses, as well as the addition of restaurants, patio areas, batting tunnels, a jumbotron, and an adjacent hotel, plaza and office-retail complex. After months of negotiations between the team, local Alderman Tom Tunney, and then-Mayor Rahm Emanuel, the plan obtained the endorsements of both the city's Landmarks Commission and Plan Commission before receiving final approval by the Chicago City Council in July 2013. To help fund the project, the team planned to more than double the amount of advertising signage in and around the stadium to about , including additional signage to be placed beyond the outfield walls – a move that was opposed by many owners of the rooftop clubs surrounding the stadium, who worried that such signage would obstruct their sightlines. Before work on the project began, the team wanted the rooftop owners to agree not to pursue legal action challenging the construction and continued to negotiate privately with them – offering to reduce the size and number of signs to be built – in order to gain their assent. The team could not come to terms with the rooftop owners who had a lease agreement with the team until 2023 in exchange for paying 17% of the gross revenues. In May 2014, the Cubs announced they would pursue the original 2013 plan to modify the park.
