Kevin Robertson, a civil engineer with Kimley Horn and Associates, presented the town's required annual NPDES/MS4 public-education update and walked the council through how stormwater moves from impervious surfaces to inlets and ultimately to the lagoon. Robertson explained the federal Clean Water Act framework and that the municipal separate storm sewer system (MS4) program requires local education and maintenance measures.

Robertson described local devices — catch-basin baskets along Old Winter Beach Road and a larger baffle box installed at Indian Lane — that trap sediment and help prevent oils and greases from entering the lagoon. He said common illicit discharges include paint, pool-cleaner chemicals, pet waste, grass clippings and concrete washout and urged residents and contractors to avoid washing paints, stucco, or concrete into roadways. Robertson asked residents to contact the building department or “Mr. Bridal” if they see illicit discharges.

Council members asked about enforcement and outreach to contractors. Robertson and town staff said permit paperwork and MS4 documentation are part of the permitting process and that field personnel (inspector Jake Mikrantz and public works employee Max Wiltius) conduct site monitoring and inlet maintenance.

Why this matters: NPDES/MS4 obligations are federally and state-mandated; local actions influence lagoon water quality. Robertson emphasized prevention and regular maintenance as key tools to limit pollutants reaching the lagoon.
