What does a builder want to accomplish on the job? Well they want to maximize their profits. How do you do that? You build as cheaply as you can, get away with any violation of building codes that you can get the local yocals to look the other way on, and you pack them shacks as close as you can. You want to maximize the number of units to be sold per acre. So clearly:
"The difference between traditional and conservational development is in the design principles."

So as usual, either the developers and their sponsors act in good faith, or building permits must be denied those that want quick dirty profits. An ongoing thing that has been around since the seventies or so. Nothing new in this supposed research that has not been brought out in hundreds of formal research projects. Same things said over and over again.

The real issue is in how willing the local governments are willing to go in not padding their pockets.

This study implies that it is the developer who insists on developing with wider roads and storm sewer systems. The reality is that it is the city planning that places these requirements on projects. It is city regulation that drives development costs up. This issue needs to be taken up with city planners, not developers who would love to develop property cheaper.
