Developers of planned subdivisions are required to build the necessary infrastructure associated with their development.However, as a result of the “Premature Platting” having been performed long before the City of Rio Rancho existed (incorporated in 1981) there is no single developer of the subdivision.Each individual property owner, when he or she builds on the individual property owned, is the developer of that lot.Therefore, a SAD places the cost of the infrastructure on the developed who, in this case, is also the individual property owner.
