First of all, the design of the manual itself is the important thing when you are developing a guidance, for example, this is a zone A, this is how the coding is worked so now, it says UPA 01, UP is Uttar Pradesh, A is what is the zone and within the zone, you might have 2, 3 typologies, so that is where the typology number. So, for example when you say, the state name and then zone; 1, 2, 3, 4, 5, like that.
Detailed Explanation
The manual's design is crucial for conveying information effectively. In this context, a coding system is used to identify various zones and their typologies. For instance, 'UPA 01' indicates that this is zone A in Uttar Pradesh, with specific classifications within that zone. Each zone can have multiple typologies represented by numbers, making it easier for users to navigate the document.
Examples & Analogies
Think of it like a library classification system. Just as books are categorized by genre and shelf location to help you find what you're looking for, the zoning and typology coding helps users quickly identify relevant information about different areas.
Classification Criteria for Zones

So, this is how and they are all classified by vulnerability to natural hazards, physiographic and access to building materials and the cultural compatibility.
Detailed Explanation
Zones are classified based on several critical factors: their vulnerability to natural hazards like floods or earthquakes, the physical geography (physiographic characteristics) of the area, access to materials needed for construction, and compatibility with local cultures. This classification helps in understanding the specific needs and risks of each zone.
Examples & Analogies
Imagine if you were planning a vacation. You would consider factors such as the weather (vulnerability), the terrain (physiography), availability of hotels (building materials), and local customs (cultural compatibility) before choosing a destination. Similarly, understanding these factors is essential for planning safe and effective construction in each zone.

So here, they have even described what actually this zone A comprises of in the high vulnerability especially to floods and what kind of floods they are talking about, what kind of riverbank erosions, they are talking about and you know, it is also talking about what kind of elevations and the forest cover, so that’s how the descriptions of each zone has been given.
Detailed Explanation
Zone A is primarily characterized by its high vulnerability to specific natural hazards, particularly floods. Detailed descriptions provide insight into the types of floods, such as riverbank erosions, elevations of the area, and forest cover, which are crucial for understanding the risks involved in construction and habitation in this zone.
Examples & Analogies
Think of Zone A as a neighborhood prone to flooding. If you lived there, you'd want to know which areas tend to flood during heavy rains, similar to how you check weather reports to prepare for potential storms. This detailed knowledge helps residents and builders plan more effectively.
