Environmentalists have raised concerns over the recent Coastal Regulation Zone (CRZ) notification issued by the Union environment ministry, stating that it has now allowed construction within 50 metres of the high tide line. They also stated that the new notification has allowed developers to change the course of tidal water, which can prove detrimental to the city. According to the new CRZ notification released on January 18, for the CRZ III areas two categories have been introduced, CRZ III A and CRZ III B. CRZ III A includes rural areas that have population density more than 2161 per square kilometre. Thus, the no development zone (NDZ) has been reduced to 50 meters as opposed to 200 meters according to the CRZ notification 2011.
