Chennai Metropolitan Development Authority is a statutory body constituted under the Town and Country Planning Act 1971.  The Authority was initially set up as an adhoc body in 1972 and acquired statutory status in 1975.  It comes under the administrative control of the Housing and Urban Development Department, Government of Tamilnadu.  The Chennai Metropolitan Development Authority has jurisdiction over Chennai Metropolitan Area (CMA) covering 1,177 sq.kilometers, which includes Chennai City, 8 Municipalities, 28 Town Panchayats and 10 Panchayat Unions.  The total population of Chennai Metropolitan Area as on date is estimated as 75 lakhs.  The main objectives of the Authority are:-

Planning for physical, infrastructural and economic development of the Chennai Metropolitan Area;

Implementing the Master Plan for Chennai Metropolitan Area and enforcing the Development Control Rules which are part of the Master Plan;

Formulating, co-ordinating and implementing projects for metropolitan development.



The Mass Rapid Transit System (Phase-I) from Beach to Thirumylai is already in operation.  The Government have accorded administrative sanction in G.O.Ms.No.297, Housing and Urban Development Department dated 27/07/98 for extending the MRTS from Thirumylai to Velachery under Phase-II for a length of 11.17 kms. at an estimated cost of Rs.605 crores.  The current estimated cost is Rs.689 crores.  The Government of Tamilnadu is bearing 2/3rd of the cost of the project and Government of India 1/3rd of the cost of the project. So far Government of Tamilnadu has contributed a sum of Rs.354 crores as grant towards GTN's share.  The CMDA is monitoring and co-ordinating the project.  The project is implemented in full swing and is slated for primary operational completion by December 2002. Spill over works on stations, etc., may continue beyond.  The expenditure incurred till 31/03/2002 is Rs. 401.36 crores. Extending the MRTS-II upto St.Thomas Mount to cover another 4.5 km. to complete a rail loop with the Chennai Beach-Tambaram suburban line is under active consideration.  CMDA has completed investigation of this proposal through the consultants.


The Mass Rapid Transist System (MRTS) Phase-I development from Chennai Beach to Thirumylai station to a distance of 8.96 km was commissioned in two stages in 1995 and 1997.  It was funded by the Union Government through the Ministry of Railways.

MRTS Phase-II development from Thirumuylai station to Velachery station for a distance of 11.17 km. is being developed sharing the cost of the Project by Government of Tamilnadu and Union Government in the ratio of 67:33 respectively.  The execution of the project is in progress as per schedule and it has been planned to commission by December 2002.

The Government of Tamilnadu / CMDA have the full right over the roof of the platform of all the nine stations to commercially exploit the air space in order to augment the supply of urban built space and enhance the travel density for operation of the MRTS.  In this regard four Consultancy firms were retained for preparation of designs for the nine stations with commercial floor area above the platform roof level.  The Consultants have submitted the detailed plans for these station developments and these designs were approved.  Station part of the construction by Railways is in progress.  The work of preparation of detailed structural designs and working drawings in respect of the commercial floors above platform roof level is completed.  Expression of interest from persons willing to take up the exploitation of the airspace above the stations will be called for after the study on demand pattern for space in all nine stations under Phase-II is completed.


The Second Phase of the MRTS from Thirumayilai to Velachery is under implementation and the system is scheduled to be commissioned by December 2002.  The MRTS has got a carrying capacity of about 60000 passengers per hour per direction.   CMDA through a Consultant has undertaken a study on densification of the developments along the MRTS Corridor at a cost of Rs.10 lakhs.  The study would recommend ways and means to achieve the objective of making optimum use of the MRTS facility for mixed activities like residences, work places, commercial centers, entertainment centers etc. all along the corridor to a depth of about 1 km. on both sides. The study is nearing completion.


In order to alleviate the existing traffic problems as well as unmanageable situations prevailing in the existing terminals in Esplanade, Basin Bridge, Broadway and MUC grounds, CMDA has proposed to develop the CMBT Complex at the periphery of the city along "Jawaharlal Nehru Salai" (Inner Ring Road) at Koyambedu.

The Government have accorded revised administrative sanction for Rs.89.21 crores and the execution works were entrusted with CMDA. The Government have undertaken the responsibility of repaying the principal and interest on the loan amount to HUDCO / TUFIDCO through yearly budget provisions.  As directed by the Government, the CMDA approached HUDCO and TUFIDCO for funding this project and the HUDCO and TUFIDCO have sanctioned a sum of Rs.84.25 crores and Rs.10.00 crores for this project respectively.   All the works are nearing completion.  The project is expected to be commissioned shortly.


A project to produce power out of vegetable waste is proposed to be implemented in Koyambedu Wholesale Market Complex (KWMC) at a cost of Rs.5 crores.  This scheme is the first of its kind in the country and is going to be implemented with 75% grant by the Ministry of Non-Conventional Energy Sources of Government of India.  CMDA will consider contributing Rs.1.25 crores as its share of 25% in the project.  CLRI is the nodal agency for this scheme and it has floated global tender inviting the participation of multi-national companies.


Eight Radial Roads for a length of 250 km. connecting Chennai Metropolitan Area are being improved at an estimated cost of Rs.212.54 crores.  The project period is 2 years.  As directed by the Government, CMDA has arranged loan for Rs.147 crores with HUDCO.  CMDA has so far drawn Rs.132.28 crores and deposited with DHRW, the agency responsible for implementing the project.

The works in eight Radial Roads are almost completed except for a few stretches in 4 roads due to Land Acquisition problem. A few bridges will also spill over.  The entire work is likely to be completed by December 2002.  The Government through budgetary support every year meets the repayment of loan with interest.   The Government have provided Rs.36.80 crores in Budget Estimate 2002-2003 towards repayment of loan and interest to HUDCO.


The Government have accorded approval for Flood Alleviation Scheme under G.O.Ms.No.321, HUD dated 12/08/1998 for implementing the structural measures in 4 packages with a total cost of Rs.300 crores.  The aim of the project is to alleviate the perennial problem causes due to Flooding and to improve the environment.

The basic objectives of the project are:-

To ensure and maintain adequate flow in the arterial drainage system;

To prevent and remove impediments to drainage;

The Government have accorded administrative sanction for the original proposal of Package-IV to be implemented at a cost of Rs.56.21 crores .  For the same, loan is to be obtained from HUDCO with work plan and schedule of works.

The revised estimated cost for the three packages works out to Rs.132.51 crores.   A sum of Rs.80.87 crores has been spent till March 2002.

The Government have provided a sum of Rs.21.56 crores in the budget 2002-2003 for  repayment of interest and loans to HUDCO.


The Chennai Metropolitan Development Authority (CMDA) is planning the formation of Outer Ring Road (ORR) on the fringe of the Chennai Metropolitan Area (CMA) to ease the traffic congestion within city area.  The Government have approved the formation of the Outer Ring Road connecting Chennai-Trichy Road (GST Road).  Chennai -Bangalore Road (GWT Road), Chennai-Thiruvallur High Road, (CTH Road) Chennai-Nellore Road (GNT Road) and Thiruvottiyur Ponneri-Panjetty Road (TPP Road).  The length of the proposed Outer Ring Road is about 62 km., connecting Vandalur in the South and Minjur in the North at an estimated cost of Rs.450 crores.  Land Acquisition work is in progress for the first Phase in between Chennai-GST and Chennai-Thiruvallur Road (CTH Road).

Award enquiry has been conducted for 15 villages and award passed for 14 villages.  The possession of the entire Phase-I stretches for a length of 29.2 kms. commencing from GST Road (Vandallur) to Tiruvallur High Road is likely to be taken by June 2002. The Tamilnadu Road Development Corporation is preparing a project report for execution of the road on BOT or similar basis. The peg marking of the alignment in Phase-II area is nearing completion.  This road will be from Tiruvallur High Road to Thiruvottiyur-Ponneri-Panchetty Road for a length of 33.10 kms.


GIS is a tool which enables to collect, manage, analyse, visualise and disseminate geo data at micro as well as macro level and helps in identifying and finding solutions to urban issues.

Chennai Metropolitan Development Authority (CMDA) has been identified as the Nodal Agency by Government of Tamilnadu to implement GIS for Chennai Metropolitan Area (CMA).  Government in G.O.Ms.No.200, H&UD dated 3/6/1998 have ordered to set up GIS in CMDA.

To create a GIS for CMA, CMDA has started preliminary works to develop and update GIS based urban infrastructure system in association with IRS, Anna University and University of Madras involving other user agencies, like CMWSSB, Chennai Corporation, TNEB, Chennai Telephones, Survey and Land Records etc.

CMDA had initiated  a programme on creation of land use Information systems, for the city.  To start with, CMDA has created land use Information system for Adayar, which enables one to view and query the land use information survey numberwise.  With this basic groundwork, it is proposed to set up an operational GIS with assistance under the TNUDP-II.

It has been proposed to implement GIS in phases since implementation of GIS requires a lot of expertise in this field.  Further implementation of GIS for the whole of CMA involves huge cost.  It has been suggested to implement the GIS in phases for the City where the pressure on land and infrastructure facilities is high and for the extended parts of the city where there is a need to support the development with necessary infrastructure facilities.

For implementation of GIS in the first Phase-I, it has been suggested to implement the GIS for Adyar,  Alandur and Sholinganallur.  GIS for Alandur Municipality is taken up which is an extended area of City, GIS for Adyar area can be taken up, since CMDA  has already created land use information system for this area and Sholinganallur has been taken up, since the area lies under the I.T. Corridor.

In Phase-II and subsequent phases the GIS can be extended to the rest of the City and other extended areas.


In the High Level Committee chaired by the Chief Secretary of the Government of Tamilnadu on 30/11/2000, it was decided to draw a Action Plan for the Cyber Corridor spelling out the requirements on infrastructure and other needed facilities for the I.T. Industries and the resultant population.  Accordingly CMDA has prepared the Infrastructure plan for Sholinganallur I.T. Corridor and submitted to Government as Phase-I.  Action plan for I.T. Corridor beyond the CMA limit and up to Thiruporur is under process.


The development of the City / CMA is managed as per the first Master Plan for Chennai Metropolitan Area.  The preparation of Detailed Development Plans for the extended areas was taken up as a follow up.  In 1996, Rs.10 lakhs had been allotted for the preparation of Detailed Development Plan and it was proposed to prepare the DDP for 57 divisions.  Out of the 57 divisions, the DDPs had been notified for 20 divisions.  Out of this, 2 DDPs for i.e., Saidapet Part-I and Part-II have reached the final stage.  For these 2 DDPs the Government has approved Map No.2 and the Map No.4 is under finalization.  12 DDPs are in advanced stage of preparation.  For the remaining 43 divisions, the collection of revenue particulars is going on.  During the current year, it is proposed to complete these DDPs.


Rainwater Harvesting replenishes the ground water table and enables wells and bore-wells to yield in a sustained manner.  Further flooding of low-lying areas and roads can be avoided to large extent by harvesting rainwater within the building premises.  Considering its importance Rain Water Harvesting has become everybody's business.

Government in G.O.Ms.No.383, H&UD Department, dated 14.9.2001 has approved and notified the amendments to DCR providing for water conservation.  By this it has become mandatory that while making any type of development, provision for Rain water Harvesting has to be made and shown in the plans for getting Planning Permission.  Before issuance of completion certificate also CMDA ensures that RWH structures have been provided as per standards and made functional.  CMDA has initiated action to familiarize the system of RWH among the Builders / Developers, not only about the methods prescribed in the DCR, but also about the improved methods developed which are more suitable for different soil conditions and different type of developments.


Renewable Energy Technology is the technology for the future.  Solar energy is a principal source which has become very attractive and is the potential available in India which can be taped locally at free of cost and it is pollution free and commercially viable.  In buildings it can be used for either water heating, space heating, etc., CMDA has initiated action to make provision of Solar Water Heating systems mandatory for certain types of buildings which may include Hospitals, Nursing Homes, Hotels, Lodges and Guest Houses, Hostels for students and trainees, Kalyana Mandapams, etc. which normally use hot water.  It is being explored whether DCR could be amended to ensure that new buildings of above categories shall be permitted only with necessary solar assisted water heating system.


The Application, Assessment and Collection of Relgularisation Fee (CMA) Rules, 1999 was first introduced to regularise the deviated / unauthorized buildings which were constructed / completed before 1/3/1999.  In view of the poor registration of applications, the Rules were amended by reducing the Regularization Fee by 50% and extending the Scheme period upto 31/12/2000.  As per the Regularization Scheme 2000, the building constructed / completed upto 31/08/2000 were made eligible for regularization.  In response for the Regularization Scheme 2000, about 16314 applications were registered, and the applicants remitted a total of Rs.98.79 crores.

In view of the public demand, the Government took a decision to revise the scheme.  Accordingly, the Government promulgated an ordinance dated 9th August 2001, by extending the Scheme period up to 30/11/2001 by reducing the fee further by 10% on building parameters related rates for the constructions completed before 31/07/2001 including individual flats.

Again the Government through an Ordinance dated 30th November, 2001 and Notification dated 5th December, 2001 further extended the last date for registration of applications up to 31/12/2001 and the buildings constructed / completed up to 31/10/2001 were included for regularization.  A total of 12714 applications have been registered with the Regularization Fee Collection of Rs.20.36 crores. CMDA and the respective Local Bodies within CMA are processing these applications.The scheme has been extended again upto 30.06.2002 to cover completed constructions upto 31.03.2002 as a last chance by reducing the rates by 50%

So far a total amount of Rs.122.06 crores has been collected as on 31/03/2002 by way of all the Regularisation schemes.
