“We have always shared a vision with the city of Wauwatosa to transform the ‘Burleigh Triangle’ from an underutilized warehouse complex into a vibrant, dense and walkable mixed-use community,” Tim Blum, executive vice president with HSA, said in the release. “With the support of city leadership and staff, we’ve gone a long way in terms of achieving that vision through the opening of the initial retail, hospitality and apartment components; but this development agreement offers the road map to completely fulfill that common goal over the next several years.”Blum later added, "We believe we have positioned ourselves well to execute the future residential and office phases by building and curating a mix of retail and restaurants that will be attractive to residents and corporate users that want to be part of a true live-work-play community." Wauwatosa Mayor Kathleen Ehley said the city is pleased to support the future expansion of the project and add more residents and employees to the area. The Mayfair Collection is a 69-acre mixed-use development where Interstate 41 meets West Burleigh Street, and includes a 146-room Hilton Homewood Suites and 269-unit luxury apartment building called Synergy at The Mayfair Collection next to 500,000-plus square feet of retail anchored by Whole Foods Market and Nordstrom Rack stores. Last summer, the developer signed a letter of intent with a potential anchor development for an office building. HSA had previously not considered office buildings for the development. The first phase of The Mayfair Collection project, which opened up in spring 2014, included the redevelopment of warehouse structures into new retail buildings, which opened. The second phase similarly transformed vacant warehouse space into a new shopping center anchored by Whole Foods and a HomeGoods, which opened in early 2016. The development also includes various other shops and restaurants. The announced development agreement comes as city officials are set to consider a separate proposal for a site just across Burleigh Street from the Mayfair Collection. Milwaukee-based Boulder Venture LLC has submitted plans to the city for a mixed-use development at 11221-11333 W. Burleigh St. that would include a Chase Bank branch, fast-casual restaurant, a car dealership and an apartment or hotel building.
