Final answer:
A subdivision developer must adhere to local zoning regulations, avoid discriminatory or private interest spot zoning, and consider the broader impact of property development on taxpayers and public infrastructure.
Step-by-step explanation:
If the street in front of a property is private, a subdivision developer must comply with local zoning regulations and land-use policies. They may be required to provide access easements or engage in certain development practices that ensure the proper integration of the private street with the rest of the community infrastructure. These practices can be influenced by pro-growth policies that favor large land development companies. However, the developer must avoid spot zoning for private interests and ensure that restrictions are not discriminatory. Furthermore, the developer must also consider the external costs that sprawl incurs on taxpayers, often advocating for 'smarter' development that integrates with existing neighborhoods and minimizes public infrastructure expenses.
