When I did a search on the web, the only thing I could find was the location of the street is in Eau-Coulee, Curepipe.
I think street names are assigned by municipalities for towns and district councils for villages.
Since the town we're talking about is Curepipe, you can start by contacting the municipality.
Here is the municipality website, try contacting them - perhaps their library and information services department!
