As it turns out, LEED v4 has changed SSc2 a bit (now called LT Surrounding Density and Diverse Uses - if the USGBC is reading this, the omission of credit numbers in v4 is not helpful, please bring the numbers back), focusing in one option on previously developed industrial sites and/or proximity to "transportation resources". You can submit your LEED v3 (2009) project attempting SSc2 as a special circumstance using the intent and requirements from v4. We were able to successfully earn the credit on a recent project using this strategy. Be sure to understand the new requirements and clearly explain how your facility meets those requirements. This won't work for all project types, but it's worth checking out. You may have to be crafty in how you develop your explanation to be sure you are adequately addressing the overall intents and requirements. You may have to pick and chose which requirements you are meeting - the more the better. Good luck!
