I found some cracked clay at the former Prudhomme's site. One can see the lake there now. This is temporary, but I don't see a timeline for when the large - really large - residential/commercial development will start.
The tract of land stretches from Victoria Ave in Vineland to the edge of the Jordan Harbour where Lake House Restaurant is. It seems to exclude the Lake House restaurant in the descriptions. This was originally Colonel J. Butler land - granted after the war of 1812.
I can imagine how many people are planned for such a large area. Grimsby's Casablanca area development will add 6,000 people in a much smaller stretch along the lake. Lincoln and Vineland populations will grow significantly with this addition.
