“Food desert” doesn’t mean “prime location for a grocery store” — often these places are food deserts exactly because they’re tough locations. For instance, dollar stores specifically target these locations and will work to drive out traditional grocery stores by selling cheap non-perishables. In addition, you often have corner stores selling produce and meat directly in neighborhoods (there are multiple on Cranston St., one on Messer, and another on Westminster). With Urban Greens, they’re competing with those corner stores plus at least one dollar store, and a butcher. Meanwhile, I would guess the local market that will basically only shop at a traditional grocery store is fairly small, likely already had an alternative (or might be doing delivery), and is easily poachable by, say, Trader Joe’s.
