The Public Works Department is responsible for maintaining our City’s storm water infrastructure and engineering improvement projects to help reduce flooding during rain events. We also review residential and commercial storm water development plans to ensure future construction projects and private development do not adversely impact current drainage systems. Lastly, we are also responsible for overseeing the federal and state Municipal Separate Storm Sewer System (MS4) permit.
