Measures needed for Urban Floods

Conservation of wetlands in urban areas like lakes, ponds, streams.
Construction of differential slope along sidewalks, roads to drain excess water into reservoirs.
Strengthening of Storm water drainage system.
Pre-monsoon desilting of all major drains to be completed by March 31 each year.
Every building in an urban area must have rainwater harvesting as an integral component of the building utility.
Concept of Rain Gardens to be incorporated in planning for public parks and on-site storm water management for larger colonies and sites those are to be developed.
Suitable interventions in the drainage system like traps, trash racks can be provided to reduce the amount of solid waste going into the storm sewers.

National Hydro-meteorological Network as per NDMA is needed for all urban cities in India.
Flood hazard assessments should be done on the basis of projected future scenarios of intensities and duration of rainfall and land use changes.
Better forecasting of rainfall events; timely dissemination of information to the mass- ‘Nowcasting’ alerts or real-time weather updates.
Restrict encroachments in natural drainage areas; clearance of river beds, proper implementation of Coastal Regulation Zone rules.
Provisions for flood-proofing of buildings
Storm water pollution control, i.e., source is controlled by imposing quality standards for wastewater and solid waste disposals in urban environments
