Shrine Hill is Davao City's major geologic and historic landmark.
Built by immense tectonic pressures of Seabed against Land mass over millions of years, the old coral reef covered seabed and older still volcanic debris were lifted skyward more than 530 feet.
Its coral outcroppings are home to many natural caves, tunnels and sink holes used by occupying Japanese for its defensive network during WWII.
Shrine Hill's Green Space cover provides the City with major contributions of life giving oxygen and reduces Climate Change contributor, carbon dioxide gas.
Shrine Hill's natural lush vegetation slows and reduces rapid run-off and the threats of flash flooding. It's absorption of rain water and later spring water production sustains life for many residents and the wild life ecosystem of the area.
Shrine Hill's natural control and absorption of rain water run-off decreases siltation of Datu Luho Creek in Ma-a and the Davao River basin. Siltation is a major contributor to flooding and loss of waterway fish production.
Urbanization of Shrine Hill, towering almost two soccer fields above Ma-a and Matina, increases its natural tendency for earth movement by increasing the load upon the mixed sand and coral gravel of its slopes.
The construction process itself disturbs partially cemented and ancient settled soils.
Unmanaged rain water pollution and run off, add to the severity and frequency of the landslide hazard.
Thus, advocates seek to protect not only Shrine Hill itself and its many benefits adding to the City's quality of life and ambiance for the public at large and tourists but also the very lives of the long-time residents along it footings.
