 Some projects eventually were cancelled or modified, such as the controversial design of a 400-metre-tall Okhta Center skyscraper, planned to be built adjacent to the historical center of the city; however, after a public campaign and the personal involvement of Russian President Dmitry Medvedev, it was relocated from Okhta to the Lakhta suburb.Another major point of criticism was Matviyenko's handling of the city's snow removal problems during the unusually cold and snowy winters of 2009–10 and 2010–11.On 22 August 2011, soon after completion of the Saint Petersburg Dam, Matviyenko resigned from office.
