This looks like too literal a translation but it seems to be a term which is in use and has quite a specific meaning - see reference below from Michie´s Legal Resources:

(a) Programmed urbanizable land Shall be constituted by land which can be urbanized according to the territorial plan in a foreseeable period of four (4) years after the date of effectiveness of the plan. This programmed urbanizable land requires an extension program.

(b) Non-programmed urbanizable land Shall be constituted by land which can be urbanized according to the territorial plan in a foreseeable period of between four (4) and eight (8) years after the date of effectiveness of the plan. The conversion of non-programmed urbanizable into programmed urbanizable land shall require that the programmed urbanizable land contain an approved extension plan and the imminent development of the programmed urbanizable land, and that at least half (1/2) of that land have preliminary or construction designs already approved. Any conversion of non-programmed urbanizable land into programmed urbanizable land shall require the drafting of an extension program and the revision of the land classification plan of the territorial plan.

Another definition, according to the Ayuntamiento de Cuenca in Spain:

El suelo urbanizable no programado queda definido como aquel que el Plan General destina a ser base del futuro crecimiento urbano, aunque no se fija una programación temporal concreta.

¡Suerte!
