Operational plans are developed along with procedures, and the aircrews and meteorologists follow those policies. It depends if you contract or if you do it yourself. Most operations begin by contracting things, but they eventually end up owning the equipment if they continue the project. This seems to be the rule. At this point, the District owns most of the equipment but is leasing the aircraft.
New radar is expensive.
Typically, these operations purchase used or Russian military Doppler radar in an effort to save money. The District has only one, but it would be helpful to have 1-2 more. Typically, such a concept is feasible. Practicality, however, is a different issue. If the cable television company wanted to provide such service, it could do so now with a subscription service.
