Environmental activists have complained to Prime Minister Narendra Modi that Navi Mumbai's Prime Minister's Awas Yojana (PMAY) is encroaching on protected mangrove zones and breaking environmental laws.

Environmental organisations say a 600-meter bund near DPS Flamingo Lake violates Coastal Regulation Zone (CRZ) standards and a Bombay High Court ruling. The local NGO NatConnect Foundation complained to the chief minister and the High Court-appointed mangrove preservation and conservation committee.
