According to the proposal, the project will be implemented in three phases covering 182 hectares: a golf course near Gate 2, another near Gates 3 and 4, and an open space near Gate 6.

For the first phase near Gate 2, the detention pond has a 361-meter perimeter, a 4,650-square-meter area, an 8-meter depth, and a 37,200-cubic-meter capacity, designed for a 25-year return period (15.6 mm/hr over 24 hours) and exceeding the needed 36,945 cubic meters.

MMDA’s schematic shows that under normal weather, water bypasses the pond and traverses the lagoon to EDSA; during heavy rains, floodgates divert flows into the pond; after rains, pumps discharge stored water slowly to EDSA toward Makiling Creek.

The scope of work covers the impounding area, an operations and power house, drainage and electromechanical works, and landscaping and golf course restoration, with a treatment facility under consideration.

Officials said operations and maintenance arrangements and a memorandum of agreement were being discussed..
