Suburban can define vastly different communities. It can be sprawling estates or still dense communities that are simply not-in-the-city. Williston Park is a solid, desirable middle class neighborhood with modest but very well maintained houses on mostly 40'x100' lots, meaning that your neighbor's wall can be just 12' away from yours... There is a broad spectrum of blue and white collar households. Good schools. Shops and restaurants. Many houses of worship. You can tell that everyone has great pride in this close knit community. I can see how the homeowner's unconventional landscaping would be a problem in this and other LI villages. As much as I love nature, I too would have a serious problem with a neighbor's "native" property. (eagerly await the backlash)
Hey, if you spend +/-850K on a house and put considerable time, money & effort to keep it neat and kept, you tend to take issue if the property next door looks abandoned. Call it social conditioning, peer pressure, unnatural or whatever you choose... It will affect the value of your single most valuable investment. If this sincere, well meaning person had a property with no neighbors for hundreds of feet or otherwise didn't impact others, I would applaud her efforts. However, in this context, it is difficult to be sympathetic.
