• By the MGB-DENR 10 to brgy. captains of Cagayan de Oro City at the Cagayan de Oro Council Environment Committee on Sept 27, 2011 ISLETS ALONG CAGAYAN DE ORO RIVER

•There are Five (5) unsurveyed Islets along Cagayan de Oro River namely: Isla de Oro (8.6 ha), Isla Delta 1 (1.3 ha), Isla Delta 2 (1.2 ha), Isla Bugnaw (1.4 ha), and Isla Bacsan (3.2 ha); with an approximate total area of 15.7 hectares. •The City Council of Cagayan de Oro passed Resolution No. 7733-2006 dated January 30, 2006 requesting a proclamation declaring and granting ownership of the islets in favor of the City to be used for eco-tourism project and other public purpose with parallel requests of Isla Delta Landless Association, Inc. (IDLAI). •On June 4, 2008, Regional Executive Director Maximo O. Dichoso, in a letter to Hon. Constatino Jaraula, then Mayor of Cagayan de Oro City, denied the request on the ground that the Islets do not qualify for eco-tourism purposes. •On October 2, 2008, Regional Executive Director Maximo O. Dichoso in a letter to Hon.Reynaldo Advincula, City Councilor and Chairman of the Committee on Subdivision and Landed Estate,again denied the request due to the nature of accretionary islets and its inherent instability. Further, prior geo-scientific studies confirmed the active and dynamic nature of this fluvial system and it would be prudent to avoid construction of houses near the river to avert potential catastrophic events. •DENR Region 10 created a committee composed of representatives from all sectors of DENR to conduct a comprehensive assessment of the area per Regional Special Order No. 2008-486. •On January 19, 2009, the Committee submitted its report recommending to the City Government of Cagayan de Oro entry of new inhabitants and construction of new units be STRICTLY PROHIBITED and that existing residents be programmed for relocation to a safer site. The islets were recommended to be used as forest park. • January 19, 2009 • September 2011
