  • Conceived the strategy for and co-wrote the amicus brief to the Massachusetts Supreme Judicial Court in Taylor v. Martha’s Vineyard Land Bank Commission, which was largely adopted by the SJC in upholding the prohibition on overburdening of easements by owners of after-acquired property, expediting a permanent injunction for a third party landowner and saving significant time and costs.
  • Tripled the number of affordable housing units in the Town of Carlisle, as Chair and principal deal maker for the Town of Carlisle Affordable Housing Trust.
  • Developed key elements of, and key evidence convincing the Legislature to adopt, the Expedited Permitting Act of 2006, including the Permitting Session of the Land Court and revisions to chapter 40A, the Massachusetts Zoning Act, to prevent appeals from blocking the effectiveness of Special Permits.
