According to the IRR of PD 957, what is the maximum length allowed for a block in a subdivision?

The correct answer reflects the regulations set forth in the Implementing Rules and Regulations (IRR) of Presidential Decree No. 957, which governs subdivisions in the Philippines. According to these guidelines, the maximum allowable length for a block within a subdivision is indeed 400 meters. This regulation is crucial in ensuring efficient design and accessibility within the subdivision layout.

Blocks longer than this specified length can create challenges in terms of accessibility for residents, emergency services, and infrastructure provision. By limiting block length to 400 meters, the rules promote a more walkable and navigable environment, enhancing the overall livability of the subdivision.

Understanding the specific limitations and standards set by PD 957 is essential for developers, surveyors, and planners, as these guidelines influence the planning process and ensure compliance with national regulations in subdivision development.
