A lot depends on what you want to do after graduation. I’ve worked with a few people from CCNY – the program is solid and current (dealing with sea level rise in NYC, etc and well versed in the big picture while also understanding solid skill set of construction and software -critical to be employable after graduation in a LA practice-). I recall UW was heavily on the construction side (though with a pretty strong ecology element). RISD, is set within an art school. current student work is a good indication of where the school is and looking at where their alumni typically end up may also help. One other aspect (however minor) is access to other fields – it’s sometimes helpful to have engineering/environmental science/psychology/etc faculty available when working in advanced studios/coursework, and if you’re proactive it’s more intellectually stimulating to have that variety of other grad students around.
Also, be very clear about a dual-degree, it’s fun but the cost is not easily justified for many (I have a dual, and the debt is nearly crippling for a newly grad; having had some work experience, it’s a bit more manageable).
