The committee that developed, managed and advocated on behalf of the Pop Up Park downtown—recently securing approval to keep it in place through the summer—is suspending those plans indefinitely after a group of merchants in town voiced opposition. According to a letter obtained by NewCanaanite.com that’s signed by 16 business owners downtown—most of them retailers, including Elm Street Books owner Susan Rein and Pimilico owner Jill Saunders (see full letter below, as well as those who added their names to it)—the Pop Up Park in occupying the final block of South Avenue at Elm Street obstructs traffic, blocks parking and displaces an important loading zone. While complimenting Pop Up Park Committee members for their passion and diligence, these merchants say, the park itself “hampers business” because its visitors do not patronize local shops and restaurants. “If it continues much longer, the small-town charm of New Canaan’s downtown is going to be overrun by big box chains just like many other towns in our area,” according to the letter, dated June 1. “The look of the Park does nothing to enhance the visual appeal of town,” the letter said.
