174 Landscape Architect and Specifier News I n f o r m a t i o n R e q u e s t # 6 1 0 It all started with four parkway planters in front of the Crate & Barrel flagship store on Michigan Avenue in downtown Chicago in 1991. The retailer's colorful, overflowing horticulture was a distinct relief to the drab gray streetscapes. That was the impetus for Mayor Richard Daley and the Michigan Avenue Streetscape Association to work together to beautify Michigan Avenue. The Michigan Avenue Streetscape project pursued an attractive but pragmatic landscape design. In 1992 Mayor Daley pledged the initial city capital to design, build and pay for purchasing and construction costs, and entreated the retailers on Michigan Avenue north of the Chicago River to pledge $200,000 annually for the first 20 years to fund upkeep costs. The city paid for the streetscape costs south of the river to Roosevelt Road, as that retail area did not have the financial resources to maintain such a project. The landscape architect—Douglas Hoerr, the young designer who planned and installed the Crate & Barrel's parkway planters—had to balance the competing priorities of the many stakeholders. Many wanted sidewalk trees, but the landscape architect knew mature trees, while stunning, would block store front views. Hoerr also argue against ornate planters, as they would cost too much to produce and maintain, leaving little money for plants. Selecting plants was a challenge; they had to endure the harsh climate, pollution and traffic exhausts. A precise mix of plants and planting scheme was required for the changing conditions, without sacrificing visual appeal or increasing costs. The basic design for the Michigan Avenue streetscape has remained the same over the decades: Three installations that correspond with the spring, summer and fall seasons are installed each year; no two years feature the same designs. The 80 median planters offer 27,000 sq. ft. of planting space and cover 33 blocks (2.3 miles) between Roosevelt Road in the Loop and Oak Street at Michigan Avenue's north end. It costs approximately $20.40 per sq. ft. for the three seasonal plant rotations. Plants are salvaged and either donated or replanted. Median maintenance is contracted out by the city to two consultant crews. A Safe Haven Foundation runs one of these crews and trains and employs at-risk youth, veterans and people recovering from substance abuse.
