Saying a new exterior design represented a major improvement if not an acceptable final version, the Planning & Zoning Commission on Tuesday night unanimously approved the redevelopment of Canaan Parish, a 60-unit housing complex at Lakeview Avenue and Route 123. Addressing concerns voiced by P&Z at an initial public hearing last month, officials representing the applicant— the 5.2-acre property is owned by the town and an organization called ‘New Canaan Neighborhoods’ owns the buildings—reduced the height of two new buildings proposed for the site by six to seven feet, added architectural features for a more local residential feel, toned down the color scheme and increased screening from the street with more robust landscaping. In the end, the redevelopment is expected to achieve one major goal of the town as well as the New Canaan Housing Authority, which is partnering with New Canaan Neighborhoods on the project—namely, to ensure that New Canaan doesn’t open itself up to a loophole in a state law that allows developers to ignore local planning decisions in places that do not meet strict affordable housing requirements. Plans call for rebuilding the 60-unit Section 8 housing complex in a single five-story structure and construction of a new, 40-unit structure of the same height that would count toward the state’s affordable housing requirement. New Canaan is never expected to reach a guideline whereby 10 percent of its housing stock qualifies as “affordable” under the state’s rigid definition, though the town by creating additional qualifying units at Mill Pond has earned four years of relief from the developer loophole.
