Ha, this will never be built.
Nor should it be.
The way in which the not-built-on landscape is organized in this 'fantasy' significantly reduces ecological benefits vs what I would hope for in an ambitious master planned community.
Having lots of random lawns as court yards is just odd.
Lots of relatively dead space.
The one argument for something like it would be rain gardens in the midst of each block; but that's not what is shown, nor is it necessary to deliver that benefit in that way.
Maximizing biodiversity and functions of temperature management, air quality and water quality are best served by two design elements; the first is large-scale contiguous forest, ideally along a natural watercourse out to the Lake; both maximizing diverse habitat, but also affording nutrient-load management benefits to water quality amongst other benefits.
The forest shown above is fragmented by mowed grass, and roads, and fails to connect to the Lake.
The secondary measure that's desirable there is to shade roads/sidewalks both to reduce the heat-island effect they throw off; but also to make walking pleasant. No such streetscape is shown.

As others have noted, the layout is also not ideal for efficient walkability, public transport etc; and thereby surprisingly car centric.

The concept, in theory, is nice; but even the high level details are dubious; not to mention unrealistic.
