NAYA RAIPUR MASTER PLAN
Designing Pedestrian Friendly Neighbourhoods in a Greenfield CityFocus: Naya Raipur Sector 31
VISION
‘Naya Raipur’ to be developed as a modern but ‘Green and SMART city’.
For conservation of the environment and existing landscape, best practices for water harvesting, waste water recycling and use of non-conventional energy resources would be adopted.
Naya Raipur designed as a citizen friendly and visitor friendly city with Non Mortised Transport (NMT) facilities.
City design would promote sense of security and comfort among its citizens, especially women, children and the physically challenged.
NAYA RAIPUR PLANNING AREA• The Development Plan-2031 consists of
three layers-
Sr. No. LayerArea

130.28 sq.km. 9 fully and 19 partly
3Layer- III(Airport Zone)
11.92 sq.km. 2 fully and 1 partly
13 Abadi areas have been included in layer -I
DEMOGRAPHIC DATANaya Raipur would act as an additional growth center taking functions from Raipur city and beyond.
Naya Raipur would attract population from Raipur, Durg – Bhilai Urban Agglomeration and various parts of Chhattisgarh.
Naya Raipur is to be developed in three phases within a period of 30 years for a population of 5.60 lakh
Phase – I 2015
Phase – II 2021
Phase –III2031
Projected Population 150,000 365,000 560,000
Natural Growth of the Existing Population 22,400 40,800
Additional Population 192,600 154,200
BALANCED LAND USE• Conservation of existing water bodies
• Conservation of existing plantation
• Recreation area 26 %
• Distributed employment centers across the city with centrally located CBD, to reduce the traffic.
• Green connectivity across the city to promote pedestrian and NMT movement.
• Grid pattern streets
1. To promote high speed roads on arterial roads
2. Alternative roads for every destinations
3. Ease in providing infrastructure.
4. Suitable for public transport system

NEIGHBORHOOD PLANNINGThe Housing strategy aims at providing
• Comfortable housing for all coupled with quality physical and social infrastructure
• Pedestrian movement based neighborhoods for convenient facilities.
• Gross residential density of each sector - 250 person per hectare
• Average population of typical sector - 16,000
TRANSPORTATION – NAYA RAIPUR
Bus rapid transit system (BRTS)
Railways – National connectivity

TOD IMPLEMENTATION
• The revised TOD chapter 9 and Chapter 18 of NRDP 2031, sent to the Government for final notification.
• Planning of Sector 7, 15-16, 31 and 32 based on TOD.
• Land use change of green strip along transit route in Sectors 7, 15, 21, 25 and 28 is in the final stage.

Designing Pedestrian Friendly Neighbourhoods in a Greenfield CityFocus: Naya Raipur Sector 31
Process | Challenges | Opportunities
The Process:
1. Workshops conducted with NRDA Staff and other stakeholders to discuss key concepts of sustainable cities…
2. Assessment of all applicable legal and regulatory frameworks…
6. Understanding what not to do…
• Junction hierarchy system not well defined
• Thoroughfare traffic encouraged through design which is not desirable
Sector 27
7. Understanding key principles of sector design…
Vibrant Streets

Typical Sector: 800m x 800m BRT alignment and station influence zone Natural features and a 100m x 100 m pedestrian access grid overlay
Gateway (50m) for intermodal access & Midway (250m) for high densities Alignment of the BRT also receiving higher densities and character Preservation of natural features
Integration of natural features and open spaces Main access corridors receiving medium density A Complete TOD
7. Understanding key principles of sector design…

PROJECT IMPACTTOD PRINCIPLES PROPOSALS
Complete streets (Walking and Biking)
Walking Grid of 150m x 150 m, Connected Greens, Safe Junctions, Bicycle Paths
Transit Supportive Uses (Active Edges)
Shared uses along the transit corridors, Mixed/Commercial Uses on the ground floor, Permeable edges.
Integrated Transport (Public Transit)
Design responds to the feeder system which supports the BRT system.
Public Spaces (Open Spaces)
Varied hierarchy, Inclusive greens, Inter-connected
Cultural Landscapes (Historic and Environmental)
The design respects the natural terrain. The valleys are retained. The traditional routes connecting the existing villages are also retained thus helping to preserve the memory of the place.
Compact development (Mixed Use and Density)
Tiered Density along the transit routes. Mixed-uses proposed at the junctions
