Here are the answers to your questions: 4.1: An urban profile depicts the height of buildings and land use patterns across different zones of a city, typically from the Central Business District (CBD) to the rural-urban fringe. 4.4.2: The building density in the CBD is high due to extremely high land values, which necessitate vertical development to maximize space utilization. 4.4.3: The transitional zone is often referred to as the zone of decay because it typically contains older, deteriorating buildings, a mix of declining residential and industrial land uses, and experiences socio-economic problems as it transitions from the CBD to more stable residential areas. 4.4.4: Two problems experienced in the CBD that have led to the mass exodus of commercial functions are: • High rental costs and property taxes: The premium on land in the CBD makes it expensive for businesses, pushing them to seek cheaper alternatives in suburban areas. • Traffic congestion and lack of parking: Difficulty for customers and employees to access the CBD due to heavy traffic and insufficient, expensive parking deters businesses. 4.4.5: The exodus of functions has had several impacts on the status of the CBD: • Decline in economic vitality: Fewer businesses mean reduced economic activity, leading to vacant properties and a decrease in overall vibrancy. • Loss of central importance: As commercial functions decentralize, the CBD loses its traditional role as the sole economic and social hub, diminishing its status. • Increased urban decay: Vacant buildings and reduced investment can lead to physical deterioration and a perception of decline, further impacting its appeal.
