Which type of zoning office is responsible for submitting final land use and zoning plans to the regulatory board?

The correct answer indicates that multiple offices are involved in the process of submitting final land use and zoning plans to the regulatory board, which typically includes the City Planning Office, the Environmental Control Office, and the Real Estate Bureau. Each of these offices plays a critical role in ensuring that land use and zoning are in compliance with regulations, environmental standards, and developmental guidelines.

The City Planning Office typically oversees urban planning and development, making it essential for creating comprehensive land use plans. The Environmental Control Office focuses on assessing the environmental impact of proposed developments and ensures compliance with environmental regulations, which is vital for sustainable land use practices. The Real Estate Bureau handles transactions and land management issues, contributing to the overall understanding of property development and zoning necessities.

Since all these entities work together to finalize zoning plans and ensure compliance with broader regulatory frameworks, it's accurate that the answer can encompass all the listed offices instead of attributing the responsibility solely to a single office.
