For three years, the city has been working on a plan that it says will provide residents with safe, comfortable and convenient ways to move to and from homes, shops, schools and businesses. That plan was unveiled Thursday by officials, who discussed it two days earlier as part of a public presentation in Council chambers. About two dozen people attended the hour-long presentation, which provided details of Palm Beach Gardens’ City-wide Mobility Plan and Mobility Fee Technical Report, which could go into effect as early as the first quarter of 2020, Planning & Zoning Director Natalie Crowley said. The plan includes transportation improvements such as sidewalks, trails and bike lanes. It also includes turn-lane improvements at busy intersections, improvements at traffic signals, and identifies strategic road and transit improvements in order to reduce congestion.
