If 6″ curbs are a must, explore the possibility of using curb cuts at regular intervals or where it makes sense….the cuts will still allow runoff to enter the depression. Clay soils? Maybe grade soil towards a central trench/basin filled with gravel. Put an underdrain at the bottom of the gravel and follow Charles’ suggestion of piping the water away. Even though you’re still ultimately putting the water in a pipe, you have succeeded in slowing it down, allowing the soil/gravel/plants to collect some sediment and pollutants, and decreased the probability for increased erosion/scouring/etc. in the nearest body of water……and feel the satisfaction of scoring one tiny victory for healthier streams
