St Luke’s School is seeking to install a synthetic turf field for baseball and soccer where a grass playing field now lays, according to an application that’s scheduled to come before the Planning & Zoning Commission Thursday. The turf field is not designed to expand athletic programs, will include no lighting or loudspeakers and “will not result in any significant increase in surface runoff from the site,” the school said. “The inclusion of a large, porous stone reservoir beneath the field will effectively capture and detain rainfall entering the turf field, promoting groundwater recharge and attenuating peak discharge to the piped system from this area,” according a report from Andover, Mass.-based SMRT. “The runoff and routing calculations demonstrate that the development will not result in any significant increase in the peak runoff from the site during design storm events of 2-year, 10-year, 25-year and 100-year return periods; therefore the project will have no significant impacts to downstream resources or receiving waters.”
St. Luke’s is seeking a Special Permit, as required under section 6.4.G of the New Canaan Zoning Regulations (page 115 here), to excavate more than 1,000 cubic yards of cubic earth and disturb more than 10,000 square feet of soil. In addition to the field, plans call for a new fenced backstop, first-base dugout, expanded concrete area for portable bleachers and relocation of the existing scoreboard to the would-be centerfield.
