Final Answer:
A subdivision is considered developed if the following condition exists on the land:
c. Roadways providing access into and travel within the subdivision have been constructed.
Step-by-step explanation:
A developed subdivision is primarily characterized by the presence of constructed roadways that facilitate access and movement within the area. Roadways are pivotal in defining a developed subdivision as they ensure connectivity, accessibility, and ease of movement for residents and visitors.
These roads not only link the different lots within the subdivision but also connect it to external infrastructure networks, such as main roads or highways, enhancing its accessibility. The construction of roadways indicates a certain level of infrastructure development, laying the groundwork for further residential or commercial construction and fostering a functional living environment.
While other conditions like the availability of water supply or the sale of lots are important factors, the presence of developed roadways is a foundational aspect defining the readiness and usability of the subdivision for habitation and activity. Thus, the existence of constructed roadways is a key determinant in categorizing a subdivision as developed.
Terefore the correct answer is c. Roadways providing access into and travel within the subdivision have been constructed.
