Repairs and improvements to stormwater detention infrastructure at the new North Lake Square shopping center on Dawsonville Highway in Gainesville have not stopped silt runoff from making its way into a Lake Lanier cove, according to residents in the area. “As the weeks go by, more and more problems surface with the project’s original design, its implementation, the inspection and reporting process, and now even the repair process,” Lakeshore Heights resident Pat Horgan wrote in a recent email to city officials. City crews have spent weeks monitoring the site since residents first noticed silt discharges from a detention pond located at the shopping center in mid-December.
