Underground parking garages eliminate a wide range of non-sustainability issues that accompany aboveground sustainable parking, including:
No stormwater runoffControl of liquid Pollution
Control of solid waste
No obstruction of views
No obstruction of sunlight
Car noise abatement
No contribution to heat islanding.
Theoretically, underground parking garages should also provide a higher level of safety and security. More safety comes from the virtual elimination of weather-related problems and height-related risks, such as falls, that are possible with aboveground parking garages. Increased security comes from the more limited access to underground parking garages compared to aboveground parking garages: there are fewer, more well-defined access points for vehicles and pedestrians. This limited access would be expected to have an inhibiting effect on criminal behavior inside the underground parking garages.
With all these advantages, why aren’t there more underground parking garages? Why isn’t there a magic button that moves all aboveground car parking garages underground.
One answer: Putting conventional parking garages underground is very expensive. The basic problem is that conventional parking garages need to be a certain size to be economically feasible…to achieve an appropriate economy of scale. Often, the economy of scale for underground parking garages is achieved with many fewer parking spaces than for aboveground parking garages. If, for example, an aboveground parking garage achieves the lowest cost per parking space with 250 parking spaces, an underground parking garage may achieve the lowest cost per parking space with fewer than 100 parking spaces. This inequality of economics is a major hurdle for underground parking garages.
Automated parking systems (APS) redefine the concept of underground car parking in many ways. One significant way is cost. An underground APS is far less costly than an underground parking garage. Faster installation and much less excavation are some others.
