Maximize the harvest: diverting water from one side of the street to the other to fill all rain gardens
A simple strategy to divert stormwater from one side of the street to the other in order to fill all the rain gardens on both sides of the street in a way that does NOT cause any flooding, but rather reduces flooding, while it also rehydrates the community and watershed and provides free irrigation water for a native food forest.
Filmed August 2022 by Brad Lancaster, just as an intense storm of about 0.6 inch (15 mm) of rain was subsiding.

Harvesting Rain from a 1,000+-Year Storm Event
In the link below, see how we transformed a 5-year, 1.5-inch (38-mm) rain event into a 1,000+-year, 19.5-inch (495-mm) rain event with a simple flow diversion. The results were fantastic.

How to maximize your harvest, maintain public path access, and avoid underground utilities with strategies that divert water from one street-side water-harvesting earthwork to another using free gravity
To calculate the ideal size of your water-harvesting basins, their capacity, and their costs see
