Coastal Zone Management Plan

Coastal Regulation Zone I

IA. The areas that are ecologically sensitive and the geomorphological features which play a role in the maintaining the integrity of the coast.

IB. The area between Low Tide Line and High Tide Line

Coastal Regulation Zone II

Areas which are developed up to the shoreline and falling within the municipal limits; includes built-up area – villages and towns are that are already well established

Approved CZMP Maps 2019

Coastal Regulation Zone III

Areas that are relatively undisturbed and do not fall under either in Coastal Regulation Zone I or Coastal Regulation Zone II and also include rural and urban areas that are not substantially developed

Between 0-200 meters from HTL is a No Development Zone

Coastal Regulation Zone IV

A. The water area from the Low Tide Line to twelve nautical miles on the seaward side

B. The water area of the tidal influenced water body from the mouth of the water body at the sea up to the influence of tide which is measured as five parts per thousand during the driest season of the year

Coastal Zone Management Plan 2019

The Government of India issued the Coastal Regulation Zone Notification in 2019, with a view to conserve and protect the unique environment of coastal stretches and marine areas, besides livelihood security to the fisher communities and other local communities in the coastal areas and to promote sustainable development based on scientific principles taking into account the dangers of natural hazards, sea level rise due to global warming, do hereby, declares the coastal stretches of the country and the water area up to its territorial water limit, excluding the islands of Andaman and Nicobar and Lakshadweep and the marine areas surrounding these islands, as Coastal Regulation Zone

  • CRZ-IA - Ecologically Sensitive Areas
  • CRZ-IB - Intertidal Zone
  • CRZ-II - Developed Land Areas (Municipal Limits / Urban Areas)
  • CRZ-IIIA - Undeveloped rural areas where the population density is more than 2161 per square kilometre as per 2011 census base, is designated as CRZ–III A and area up to 50 meters from the HTL on the landward side shall be earmarked as the 'No Development Zone (NDZ)'
  • CRZ-IIIB - Undeveloped rural areas where the population density of less than 2161 per square kilometre, as per 2011 census base, is designated as CRZ-III B and the area up to 200 meters from the HTL on the landward side shall be earmarked as the 'No Development Zone (NDZ)'
  • CRZ-IVA - The water area and the sea bed area between the Low Tide Line up to twelve nautical miles on the seaward side shall constitute CRZ-IV A
  • CRZ-IVB - areas shall include the water area and the bed area between LTL at the bank of the tidal influenced water body to the LTL on the opposite side of the bank, extending from the mouth of the water body at the sea up to the influence of tide, i.e., salinity of five parts per thousand (ppt) during the driest season of the year.
