The City of Celina Planning and Development can help you determine the zoning, which dictates the legal future uses of the parcel. Here is their contact information:
Cindy Jackson phone: 972-382-3617
Ask if they know of any current development plans and timelines. We do this type of research for clients routinely, and find the planning and zoning departments to be generally very accessable, friendly and helpful. Hope this helps!
