Lakefront residents tell council sediment from nearby construction is clogging Nivens Creek and damaging docks

Several lakefront residents told the Tega Cay City Council on May 18 that sediment from nearby development has accumulated in Nivens Creek and the delta by the Beach Club, making private docks difficult or impossible to use.

Speakers — including Mike Becker (spelled 'Bekker' in one instance in the transcript), Lisa Prondzinski, Mark Dye and Gus Matchunis — described recent rains carrying sediment from The Grove and Trinity Townes construction into the creek and delta near Serenity Point. They said the buildup has reduced navigable water depth, interfered with dock use, and could lower property values for waterfront lots. Some asked the council to halt construction until a mitigation plan is in place and requested a meeting with developers and responsible parties; others suggested dredging as a potential remedy.

Council did not take immediate enforcement action during the meeting. The City Manager previously noted Right of Way acquisitions for the Grey Rock Trail and that The Grove is installing underground infrastructure and preparing for a roundabout; he also reminded residents about backflow prevention device testing due June 1, 2026. Councilmembers encouraged residents to provide details to staff so the city can investigate and coordinate with developers and relevant agencies.

The council did not announce a timeline for an interparty meeting or dredging study at the meeting; residents asked the city to convene affected parties and explore accountability measures.
