in 2013. LPPCHEA is composed of the Freedom Island in Parañaque and the Long Island in Las Piñas that covers 175 hectares and features a mangrove forest of eight species, tidal mudflats, secluded ponds with fringing salt-tolerant vegetation, a coastal lagoon, and a beach. Government and politics The framework of government and governance in Metro Manila is based on Republic Act No. 7160, otherwise known as the "Local Government Code of 1991". This law outlines the powers and responsibilities of all local government units (LGUS) in the Philippines and thus forms the basis of inter-local governmental relations among the area's constituent local governments. The local government code grants these units significant political and administrative autonomy in accordance with the principles of decentralization and devolution of power. This situation presents a challenge to the coordination of policy and service delivery across the multiple autonomous local government units and is thus the underlying dilemma of metropolitan governance in Metro Manila. The Metropolitan Manila Development Authority (MMDA) is the agency responsible for the delivery of public services in Metro Manila. Its services are limited to traffic management and garbage collection. Previously Metro Manila was governed by a regional government authority, the Metro Manila Commission and was led by a governor. A bill was introduced in 2014 proposing the creation of a new governing body in Metro Manila to be known as the Metropolitan Manila Regional Administration (MMRA). Unlike the MMDA which is limited to being an administrative coordinating body, the proposed MMRA will have police and other typical municipal powers and is more akin to the Bangsamoro Autonomous Region in Muslim Mindanao. Metro Manila, the National Capital Region, is the seat of the national government. All the main offices of the executive departments of the country are in Metro Manila. The Department of Agrarian Reform, Department of Agriculture, Department of Environment and Natural Resources, National Housing Authority and Philippine Coconut Authority has their main offices based around Quezon Memorial Circle in Quezon City. Manila, the capital city of the country, is the home to Malacañan Palace, the official residence and office of the President of the Philippines. The city is also the home to the Supreme Court of the Philippines. Other key national institutions based in Manila are the Court of Appeals, the Bangko Sentral ng Pilipinas, and the Departments of Budget and Management, Finance, Health, Justice, Labor and Employment and Public Works
