joint degrees in planning n law? pls help...

hello all..
I've just completed my bachelors in architecture from another country and i'm trying for a masters here in the US.. My area of focus is urban and environmental planning... I will shortly be taking the LEED NC exam.. I'm also looking at dual degrees and noticed that a lot of univ's offer dual degrees in planning and law.. (MUP/JD or MRP/JD). Though i have seen so many univ's offering this course, i hav'nt been able to get in touch with anyone that actually has this kind of qualification...

well, i really don't understand this.. What kind of job openings can one look to with this kind of degree? Will it be with a law firm , largely with a legal base, suing any legal aberration from what the zoning laws and building codes dictate? or will it be more of a planners job with a largely a planning base, if i choose to specialise in say, environmental law? i have read far too many blogs of architects and planners even struggling 2 pay back their loans from grad school.. I'm going to have a fortune to pay back in loans too... :( Will this qualification land me on a better pedestal at least on the pay check front?

Can someone clear me this if u r familiar/ in the related field? I'd really appreciate your inputs... Thanks in advance for any help.. :)
