Sometimes open drains do not discharge to a drainage system. They may be terminated in a landscape area. The photo above shows a footpath spoon drain that drains to a newly created landscaped area.
There is nothing necessarily wrong except that it puddles for a while after it rains. This is the entry to a kids playground and creates a nuisance to the users to the park.
In my experience many parks are developed without necessarily thinking about stormwater drainage. This is unfortunate as i believe drainage is a necessary consideration to landscaped architecture.
It is important to reduce the amount of impervious area that discharges to natural water bodies. It is good that in the above example that stormwater is disconnected from draining into the underground system. But it can be done better so that it does not create a nuisance.
