Lulu and Nimby are always with us, as resistance to the siting of various land uses occurs, and, now, the latest focus is the proliferation of warehouses. They are popping up all over the landscape.  In New Jersey, though, there is a bill pending in the State Senate to give a voice to those living in neighboring municipalities when one municipality has a proposal and wants to site a warehouse, given the attractiveness of tax revenue and job, but adjacent municipalities may have concerns about traffic, lost revenues and more.  What the pending legislation does not do, however, is to provide for a process to assist negotiations among the parties at interest before final decisions are made.  This column makes the case for third-party assistance, principally mediation.
