Long Island Municipal Law, Land Use, Zoning & Planning

After twenty years of practice in the area of zoning and planning, there are very few situations that Sean Walter has not seen.  Using research, analysis, and experience, along with strong relationships with the Town of Brookhaven and all five East End towns and villages, he can advise developers in ways that other firms can not.

Sean Walter’s knowledge of municipal law started early on in his career while working for a prominent Southampton municipal/zoning and planning lawyer.  That experience led to working for six years as a Town of Riverhead Deputy Town Attorney which culminated in serving as Riverhead Town Supervisor from 2010-2017.  Mr. Walter’s knowledge of municipal law and zoning and planning is unparalleled in the legal community today.  His experience sitting on “both sides of the isle” makes him well-suited to advise clients who face major regulatory battles.

As the former Riverhead Town Supervisor (2010-2017), Sean Walter presided over the subdivision of the largest tract of land on Long Island.


Mr. Walter was directly responsible for the Enterprise Park at Calverton (EPCAL) Reuse and Revitalization Law which enabled a 90 day default approval of projects located at EPCAL.

This combined with directly working with developers to bring over $100,000.000 in investment to the Riverhead downtown area in a one year period makes him uniquely suited to represent clients with their development projects on Long Island.

We understand that time is money in the business community and that most developers strive to make the best products to eventually turn out a profit.  Our aim is to express a pragmatic approach to projects while protecting our client’s rights.
