As urban areas become more dense, land values increase, and the demand for space becomes more challenging, developers are seeking alternative innovative approaches to parking cars that allow a project to proceed while meeting all parking and sustainability requirements. High-density parking (HDP) systems are able to park 30%–400% more vehicles than a traditional garage in the same amount of space. This course explains the origins, history, and types of high-density parking. The sustainable advantages of HDP systems are examined and design considerations are discussed.
