Coastal Zone Management Plan of Tamil Nadu As per CRZ Notification, 2011

What the report covers

The Coastal Zone Management Plan of Tamil Nadu As per CRZ Notification, 2011 provides the mapping and classification framework for Tamil Nadu's coastal areas. The National Centre for Sustainable Coastal Management prepared it after field surveys, with technical support from the Department of Environment, Government of Tamil Nadu and the Tamil Nadu Coastal Zone Management Authority.

The report is identified for official, administrative, public and operational use. It includes coastal databases, maps, area statistics and details of coastal villages covered by individual map sheets.

Who may need to use it

The Coastal Zone Management Plan may be relevant to buyers, owners and professionals reviewing land in coastal Tamil Nadu. Its maps and tables identify Coastal Regulation Zone categories, regulation lines, ecologically sensitive areas and hazard information that may be associated with a coastal location.

Users can refer to the report for:

• Coastal Regulation Zone classifications I, II, III and IV.
• Sheet based classifications of ecologically sensitive areas and Coastal Regulation Zone categories.
• Details of coastal villages falling under each OSM sheet.
• District based Coastal Regulation Zone area statistics.
• Lists of municipalities and town panchayats included in the classification work.

Main mapping provisions

The Coastal Zone Management Plan describes how the High Tide Line and Low Tide Line were demarcated. The features considered include beach berm crests, seawalls, revetments, embankments, permanent vegetation lines, coastal sand dunes, mangroves, rocks, headlands, cliffs and areas influenced by tidal action.

The report also maps or records:

• Mangroves, coral reefs, reserve forests and sand dunes.
• Salt marshes, seagrass and mudflats.
• Bird and turtle nesting grounds.
• Marine protected areas.
• Archaeologically important and heritage sites.
• Salt pans and aquaculture ponds.
• Critically vulnerable coastal areas and integrated management plans.

Hazard line and preparation

The Coastal Zone Management Plan includes hazard line demarcation and its impact. The listed methodology covers tidal data processing, creation of a digital elevation model, delineation of flood and erosion lines and final hazard line demarcation. The Survey of India and the National Centre for Sustainable Coastal Management performed the roles identified in the report.

The documentation sheet names the National Centre for Sustainable Coastal Management as the authorised institute under Letter No. J-17011/8/92-IA-III dated 14th March, 2014.
