I would suggest a motion to install a fence in the coming year out of the existing grounds maintenance budget if that is feasible. You might be surprised how many people would resist having any increase in the budget for money spent on common property facitilies that they don’t use themselves. They can’t see past their wallets to see that a suite of facilities makes the place nicer to live in, provides more opportunities for neighbours to meet and perhaps become friends. They can’t even see that such things increase the value of their units even if they are stay indoors curmudgeons themselves.
We have various facilities, all of which are only used by a minority but the minorities are different. Some use the tennis court but not the BBQ, some use the BBQ but not the playground. I used to use the playground when my kids were younger but not now. Perhaps I will use it later if I have grandkids. Some use our open spaces to walk or kick a ball, many do not. Once something is in place people don’t seem to object but it is a hurdle to get over that only a minority expect to see a benefit from any particular change and even they will be luke-warm in their support:
“ We must bear in mind, then, that there is nothing more difficult and dangerous, or more doubtful of success, than an attempt to introduce a new order of things in any state. For the innovator has for enemies all those who derived advantages from the old order of things, whilst those who expect to be benefited by the new institutions will be but lukewarm defenders. This indifference arises in part from fear of their adversaries who were favoured by the existing laws, and partly from the incredulity of men who have no faith in anything new that is not the result of well-established experience. Hence it is that, whenever the opponents of the new order of things have the opportunity to attack it, they will do it with the zeal of partisans, whilst the others defend it but feebly, so that it is dangerous to rely upon the latter.”
Niccolò Machiavelli
The Prince
So, if you can make it so that this particular upgrade is out of the general grounds budget without any increase you might have more success.
What if it were couched in broader terms? Perhaps a proposal for ‘sprucing up’ this particular bit of the grounds with a seat, some more interesting plantings around an open area and the fence that would make it safer for families to use. Perhaps it could be useful to have some ambiguity about what is maintenance vs. additions to the common property. Surely it is maintenance even if a bit of grass is replaced with some bushes.
