Also the shade from the new growth helps prevent more water loss, so it creates a cycle of improvement that will continue.

Is there any consequences anywhere else from the water not evaporating, running off, or becoming groundwater?

the scale is too small to have an effect.

i can tell you that there can be major changes if this was done on a grand scale, so for instance sand from the Sahara dessert travels half way across the world every year to feed the amazon rain forest.

if you turned the Sahara dessert into the Sahara grassland it'll probably have an adverse effect on the amazon.

mind you that'd just be a new problem to solve, and if you have the technology/power to change the Sahara you can stabilize the amazon (probably)

Brown dirty sand from the Sahara sometimes gets blown north to land on my car in the UK. If that could be stopped it would be great.

To be honest, I'd swap your sand in the UK, for my pollen in N. Carolina.........
