A for-profit company has proposed the construction of a Free-Style Aerial Ski Jump on land that is zoned for commercial use in our town. The problem is that there is no appropriate use classification for this facility applicable to the commercial zoning classification. The only use classification that the Planning Board could assign was that of "Recreation Center". Unfortunately our zoning regulations do not have a definition of a recreation center and many feel that this classification is improper and will be challenged successfully by those who oppose the construction of this facility. Is there a definition that is generally accepted by planning boards and/or which has been tested in court?
