Yes, a project can earn ID credit for being in a LEED for Neighborhood Development certified project. The LEED-ND project must be certified, not just registered. LEED-ND projects at any certification level (Certified through Platinum) and any stage of certification (Stage 1, 2, or 3) are eligible.
**Update October 1, 2013 - The ruling below is no longer valid for project registered after 7/1/2013. As many prerequisites and credits within LEED-ND and LEED-NC address similar concepts, simply locating a NC project within LEED-ND neighborhood is not considered innovative and in some cases, can lead to double-counting the use of the same strategy in both Rating Systems.
