This was mentioned and predicted going back to early posts in the thread, posts #16 and #24. There was not a lot of support for the ideas even though it's as or more likely than most other options or suggestions. It appears to be a high level project with the lack of normal permits and the speed it was started. It's certainly not some poor local or beach bar owner type of tourist responsible for and funding it.
The timing also suggests that it is somehow connected to the beach development or meant to take advantage of it and the expected large groups of weekend visitors from Santiago and other reasonably close locales.
What else could it be?

Looking at "progress" on this project gives you an idea what one is dealing with.
A Dominican project just like the beach improvement, zero urgency just talk.
If a pedestrian path continues to the beach will depend on the beach land owner.
They may not want hordes of people traversing their property,
Disturbing owners in their condos.
There may well be only an entrance in Charamicos and Sosua to the beach.
Peoples opinions and "support has zero bearing on what the land owner will do.
He will negotiate with the government on what his project entails, if permits are needed and payments need to be made.
