Smart City
Smart cities can be identified (and ranked) along six main axes or dimensions. In particular, the axes are based - respectively – on theories of regional competitiveness, transport and ICT economics, natural resources, human and social capital, quality of life, participation of citizens in the governance of cities.

For milder slopes, it’s important to ensure adequate drainage is provided to avoid nuisance ponding (a raingarden along the full
length of the swale will provide this drainage). Runoff can be directed into raingarden swales either through direct surface runoff (e.g. with flush kerbs) or from an outlet of a pipe

Smart City
A city can be defined as ‘smart’ when investments in human and social capital and traditional (transport) and modern (ICT) communication infrastructure fuel sustainable economic development and a high quality of life, with a wise management of natural resources, through participatory action and engagement. (Caragliu et al. 2009). To Gildo Seisdedos Domí nguez, the smart city concept essentially means efficiency.
