As mayor, Sanders also led extensive downtown revitalization projects. One of his primary achievements was improving Burlington's Lake Champlain waterfront. In 1981, he campaigned against the unpopular plans by Burlington developer Tony Pomerleau to convert the then-industrial waterfront property owned by the Central Vermont Railway into expensive condominiums, hotels, and offices. He ran under the slogan "Burlington is not for sale" and successfully supported a plan that redeveloped the waterfront area into a mixed-use district featuring housing, parks, and public spaces.
