Sector 34

Per-Category Scoring

Each category scores 0-100 based on how many amenities are found within a specific radius:

How Noise Levels are Estimated

Daytime and nighttime noise levels (dB) are estimated using the FHWA Traffic Noise Model (simplified). The model calculates noise attenuation based on distance:

Nighttime noise is estimated to be 5–10 dB lower than daytime (reduced traffic, no industrial operations). Multiple sources are combined using logarithmic addition.

CPCB Noise Standards (India)

The Central Pollution Control Board classifies areas into 4 noise zones with specific limits:

Worked Example

Data Sources

• OpenStreetMap (via Overpass API) — highway, industrial, and railway proximity data
• FHWA Traffic Noise Model — simplified noise attenuation estimation
• CPCB Noise Rules, 2000 — ambient noise standards for Indian cities
• WHO Environmental Noise Guidelines (2018) — health-based recommended limits

ODF Certification Levels (SBM Urban)

The Swachh Bharat Mission Urban uses a three-tier ODF certification framework:

Worked Example

Why Sanitation Matters for Health

• Waterborne diseases — Poor sanitation increases risk of cholera, typhoid, and hepatitis A
• Vector-borne diseases — Stagnant water from poor drainage breeds mosquitoes (dengue, malaria)
• Child mortality — WHO reports that improved sanitation reduces diarrheal deaths by 36%
• Groundwater contamination — Open drains and septic tank leakage pollute drinking water sources

Data Sources

• Nagar Nigam Raipur — City Sanitation Plan (CSP) ward-level data
• AMRUT SLIP — Service Level Improvement Plan for sanitation benchmarks
• SBM Urban Portal — Swachh Bharat Mission ODF certification data
• NGT Reports — National Green Tribunal compliance monitoring
• NRANVP Development Plan — Nava Raipur sector-level infrastructure data

The Flood Risk Score measures an area's vulnerability to river flooding and urban waterlogging. Lower score = safer area.

Parameters & Weights

Formula

Worked Example

Zone-wise Risk Overview (Raipur)

Key Risk Factors

• Kharun River — Primary flood source. Wards along the river corridor (Zone 9) face highest risk during monsoon.
• Telibandha Lake — Overflow during heavy rains causes waterlogging in Shankar Nagar area (Zone 3).
• Old City Drainage — 52% drainage gap in RMC limits. Old areas (Pandri, Railway) suffer most waterlogging.
• Mahanadi Basin — Entire Raipur district drains into Mahanadi via Kharun, Pairy, and Seonath rivers.

What This Means for Home Buyers

• Score ≤ 20 — Safe zone. Minimal flood risk, standard construction sufficient.
• Score 21-40 — Moderate risk. Check monsoon waterlogging history before buying.
• Score 41-60 — At risk. Consider elevated construction, flood insurance, basement waterproofing.
• Score >60 — High risk. River flooding possible. Verify RERA flood disclosure and avoid ground floor investment.

Data Sources

• NDMA — National Disaster Management Authority, District Disaster Management Plan
• ThinkHazard — World Bank global hazard assessment for Raipur district
• CGWB — Central Ground Water Board, Raipur district hydrogeological report
• RMC SLIP — Raipur Municipal Corporation storm-water drainage plan

The Livability Report is a single number (0–100) that represents the overall quality of life in a neighbourhood. It is the simple average of all available sub-scores.

Formula

Sub-Scores Used

Infrastructure score is planned but not yet included. Only parameters with available data are averaged — NULL values are skipped, not treated as zero.

Worked Example

Grade System

What Does the Score Mean for You?

• Home Buyers — Use the score to compare neighbourhoods objectively. A higher score means better air, water, safety, amenities, and environment.
• Renters — Check if the area's livability matches the rent being asked. A Grade C area should not command Grade A pricing.
• Investors — Areas with improving scores (check the trend chart) may see property appreciation. Grade B areas with rising scores are sweet spots.
• Families with Children — Pay special attention to Air Quality, Green Cover, and Amenities (schools, hospitals) sub-scores.
• Senior Citizens — Quiet Score, Air Quality, and nearby hospital access (Amenities) are most relevant.

Important Notes

• The composite score uses an equal-weight average — all parameters contribute equally.
• Risk parameters (Flood, Earthquake) are inverted before averaging so that lower risk = higher livability contribution.
• If a sub-score is unavailable (e.g., Infrastructure), it is excluded from the average, not treated as zero.
• Scores are recalculated whenever new data becomes available. Check the trend chart for historical movement.
• The score reflects current conditions — an area under rapid development may see score changes over time.

The Earthquake Risk Score measures an area's seismic vulnerability based on soil type and amplification potential. Lower score = safer area.

BIS Seismic Zone

Why Soil Type is the Differentiator

Since all of Raipur is uniformly Zone II, the only meaningful differentiator is soil type. Soft, saturated, or filled soils amplify distant earthquake shaking more than hard alluvial or laterite soils. This is called site amplification effect per IS 1893.
