What are Coastal Regulation Zones (CRZ)?

• Coastal Regulation Zones (CRZ) are the areas along the 7,500 km-long coastal stretch of India.
• The coastal land up to 500m from the High Tide Line (HTL) and a stage of 100m along banks of creeks, estuaries, backwater and rivers subject to tidal fluctuations, is called the Coastal Regulation Zone.
• The development of buildings, tourism infrastructure and other facilities is regulated in these areas by the Government of India.
• Coastal areas are of four categories as CRZ-1, CRZ-2, CRZ-3 and CRZ-4.
  • CRZ-1: These are ecologically sensitive areas which are essential in maintaining the ecosystem of the coasts. These include national parks/marine parks, sanctuaries, reserve forests, wildlife habitats, mangroves and corals/coral reefs.
  • CRZ-2: The areas that have already developed up till the shoreline of the coast are included in this zone. Construction of unauthorised structures is prohibited in this zone.
  • CRZ-3: Rural and urban localities that are relatively undisturbed and do not belong to the first two categories are included under CRZ-3. Only specific activities related to agriculture or some public facilities are allowed in this zone.
  • CRZ-4: These areas include the coastal stretches in Lakshadweep, the Andaman and Nicobar Islands and some other small islands, except those termed as CRZ-I, CRZ-II, or CRZ-III. These areas reside in the aquatic region up to the territorial limits.
