Commission members and staff repeatedly asked whether stormwater from the site is pretreated and whether the project’s detention would meet the 80th‑percentile retention requirement under state rules. “As long as you’re treating your discharges before they leave your site, that’s all that’s required,” said Greg (no role specified) during the discussion.
