You should first check your deed restrictions. If it then appears that what you want to do may be possible, work up a plan to submit. It is hard for them to say what may or may not be possible. Each district has its own restrictions, they do vary. And even if something is within restrictions, how do they say yes or no without a detailed plan? If you are having a contractor do it, they may help you with this. The contractors and landscapers we have used had existing relationships with people at the ARC.
