Effectiveness of low impact development practices in two urbanized watersheds: retrofitting with rain barrel/cistern and porous pavement.

The L-THIA-LID model can be used to inform management and decision-making for implementation of LID practices at the watershed scale and indicates that the application of 50% rain barrel/cistern, 50% porous pavement and 25% rain Barrel/ cistern combined with 25%, porous pavement are good retrofitting options in these watersheds.
