I am trying to enlist here some of the best practices that I have seen/heard about City Management. Please feel free to add, edit/dissect as you may please.
1. Locality based Infrastructure Management - A la Delhi model can be adopted by empowering local Residents' associations, where available, to get Infrastructure like Roads, Parks, Water and Waste management managed and maintained on a locality basis and make engineers and other city corporation employees answerable to such associations as well as to their own management. This can lead to quick addressal of grievances and form power centres for effective infra management. In Delhi, residents' associations are headed by retired govt. employees who have plenty of time on their hands and a vision for their locality.
