CCZM Guidelines



Guidelines for the Implementation of Colour Coded Zoning Map (CCZM)  (Implemented in co-ordination with Local Bodies)

1. Safeguarding the Airspace around the Aerodromes
1.1. The effective utilization of an airport is considerably influenced by natural features and man-made constructions inside and outside its boundary. These may result in limitations on the distances available for take-off and landing of aircraft. For these reasons certain areas of the local airspace must be regarded as integral parts of the aerodrome environment. Also, there is a need to protect the airport environment so that future airport expansion plans are smoothly implemented.
1.2. International Civil Aviation Organization (ICAO) and DGCA have defined Obstacle Limitation Surfaces (OLS) in and around the airports for safe and efficient operations of the flights. Accordingly, Ministry of Civil Aviation has issued Statutory Order (S.O. 84 E) dated 14th January, 2010 to protect these surfaces.
1.3. Airports Authority of India (AAI) has been given the responsibility for issuing the ‘No Objection Certificate’ for height clearance for buildings/ structures/ Chimneys/ masts, etc. on behalf of Central Government in respect of civil aerodromes in India. For the Defence Airports, responsibility has been assigned to the respective Defence Authorities.

2. Implementation of CCZM by MoCA
2.1. In line of the world best practices and based on the Committee recommendations, set up by MoCA for regulating the building construction around airports, MoCA (vide its letter dated 15th October 2012) has directed AAI to prepare the Colour Coded Zoning Map (CCZM) in grid form of all the civil airports, certify them and give copy of such maps to Local/Municipal Bodies.
2.2. CCZM of Mumbai, Navi Mumbai, Delhi, Kolkatta, Hyderabad, Lucknow and Ahmedabad have been prepared and issued to the Local Bodies. The same have been uploaded on AAI website for easy accessibility to everyone.

3. Responsibility of the Local, Municipal or Town Planning and Development authorities
3.1. The concerned the Local, Municipal or Town Planning and Development authorities to approve construction of buildings as per their own building regulations/bye-laws up to the heights indicated in CCZM. For such buildings, NOC for height clearance is not required from AAI.
3.2. No such approval shall be given by the Local, Municipal or Town Planning and Development authorities for sites which lies in approach, take off and transitional areas of an airport or in any other area, marked in the Colour Coded Zoning Map for the compulsory obtaining of No Objection Certificate from the designated officer or authorised officer.
3.3. The Local, Municipal or Town Planning and Development authorities shall certify on the sanction plan that the Floor Space Index or Floor Area Ratio and the related height of the building or structure is within the permissible elevation as indicated in the Colour Coded Zoning Map for the given site.
3.4. The Local, Municipal or Town Planning and Development Authorities shall submit the details of structures so approved to the concerned Airport Operator, within a period of thirty days from the date of such approval.

4. How to interpret and implement the CCZM:
4.1. Applicant needs to locate his plot/site in CCZM and identify the home grid, where the plot/site lies.
4.2. Co-relate the colour of the home grid with the colour legend, available in CCZM and check the permitted top elevation in Above Mean Sea Level (AMSL). If the color of the home grid is red then the applicant shall file application to AAI through NOCAS at AAI website for issuance of NOC.
4.3. The heights indicated in CCZM are Above Mean Sea Level (AMSL).
4.4. Deduct the site elevation or the reduced level of the plot from the permitted top elevation to get the height Above Ground Level (AGL).
4.5. Approach the concerned Local Body for building plan approval if the requested height is below the CCZM permitted top elevation.
4.6. If the desired height is more than the CCZM permitted top elevation, file NOC application to AAI through NOCAS at www.aai.aero .

5. Benefits of CCZM implementation:
5.1. Ease of doing business with AAI as NOC for height clearance is not required for the buildings up to the CCZM permitted top elevation
5.2. Whole of the area around the airport has been divided in geo referenced grids of 1 minute by 1 minute (approximately 3 Square km) for the easy readability and implementation.
5.3. The Local, Municipal or Town Planning and Development authorities can plan their development as per the CCZM.
5.4. Work load of NOC processing team in AAI is reduced.
5.5. SACFA in Ministry of Communication and IT shall also use the CCZM for the issuance of mast clearance.

6. Punitive Action in case of violation
6.1. Building heights around an aerodrome are regulated by as per the provisions of Govt. of India (Ministry of Civil Aviation) Statutory Order S.O. 84 E dated 14th January, 2010 to facilitate safe and efficient aircraft operations. The violations of these regulations are dealt under the “The Aircraft (Demolition of Obstructions caused by Buildings and Trees etc.) Rules, 1994.
6.2. To avoid action as per 6.1 above, applicant shall ensure that the data, filed to the Local, Municipal or Town Planning and Development authorities and/or AAI for seeking height approval of buildings, is accurate.
