It’s entirely possible for a community of 10K to find themselves in D3/D4 without trying. Many urban, and an increasingly large number of rural communities, have residents that have raised their kids and remain in their homes. Without available housing, a community is not inviting to younger families. It’s been mentioned on here before, but there are kids leaving RH to attend neighboring districts, charters and private schools. Factor those things together and you have a small student body. A quick look at Google Maps shows a community with little land to develop and grow. Many green spaces are designated park areas, so I would anticipate them being in a lower division going forward. I am not entirely familiar this situation, but some of these parents might be moving their families to RH to escape neighborhoods like this one in East Cleveland:
