1.3 Topography
1.3.1 Cagayan de Oro City is characterized by a narrow coastal plain along the Macajalar Bay and by highland areas separated by a sleepy inclined escarpment. The lowland is relatively flat and its elevation is not more than 10 meters above the mean sea level. The highlands bound the City in the south from east to west. They consist of plateaus, terraces and gorges.
1.3.2 Creeks and rivers traverse and drain to Macajalar Bay. There are seven rivers namely: Cagayan River, Iponan River, Bigaan River, Cugman River, Umalag River, Agusan River an Alae River. The more notable creeks are Binono-an, Bitan-ag, Indulong, Kolambog, Sapong, and Umalag.
1.3.3 About 13,587 hectares or 28 percent of the City’s land area have a slope between 0 and 8 percent, which is appropriate for most uses. Such areas are concentrated on the narrow coastal plain, the flood plain areas of the Cagayan and Iponan Rivers, and in the upland terraces. The remaining 72 percent of the land have slopes that are greater than 8 percent, which pose a challenge to development.
1.4 Geology
1.4.1 Geomorphologically, Cagayan de Oro can be classified into three broad landforms: lowlands; level uplands; and hills/mountains. The lowlands contain five distinct forms, namely:
· Sandbars. These are narrow, elongated strips of sand deposits formed by wave action on some section of the coastline. The extent is insignificant.
· Tidal Flats. These are low coastal areas, subjected to tidal influence found mainly between the mouths of Cagayan River and Iponan River.
· Coastal Alluvial Plain. This is the narrow strip of level area from Puerto in the southeast to the center of the city.
· Broad Alluvial Plain. This is found in a limited patch around a small hill south of the city.
· River Flood Plain. The Iponan and Cagayan Rivers have formed as extensive flood plain that coalesced north of the Cagayan-Iligan Highway. Such areas may be subjected to brief flooding during extraordinary rainfall events.
The uplands are classified into three (3) forms:
* Terrace or Plateau. There are three distinct plateaus that exist within the city limits. The most extensive one occupies the southeastern region. Another plateau is situated west of Cagayan River along the road to Lumbia and Talakag of Bukidnon. The third is in the south-central region just north of Barangay Indahag.
It covers 80 barangays, 63 of which are urban, namely:

1.4.1 Land Use
The city has assumed a role, which is larger than its physical boundaries. It is the second highest-ranking urban settlement in the island of Mindanao, and is considered the most important center of a growth corridor occurring on the northern coast of Mindanao. Spanning a 187-kilometer strip and covering about 3,100 square kilometers, the Cagayan-Iligan Corridor (CIC) area has about 1.06 million residents and is endowed with rich agricultural and natural.
Because of these, it has been experiencing dramatic growth in economy which thereby instigates major amendments on the 1979 Zoning Ordinance.
| Land Use | Area (sq. km.) |
| Agricultural | 21,047.4487 |
| Non Agricultural | 27,838.383 |
| - Residential | 5,974.6630 |
| - Commercial | 175.6048 |
| - Industrial | 170.4562 |
| - Special Class | 13.1038 |
| - Other Properties | 29.9856 |
| - Exempt Properties | 1,178.7707 |
| - Open Spaces | 20,295.7972 |
· Piedmont. This is an extensive upland area located along the road to Barangay Indahag and along the road to Malaybalay, Bukidnon.
· Canyon/Gorge. These are the almost vertical walls along the very deeply incised river channels. The width of the canyon/gorges ranges from 500 to 1000 meters.
The hills/mountains take five different forms, as follows:
· Escarpment. This is the steep slope separating the lowland plains from the hilly areas. In some sections, the slope is almost vertical.
· Conglomerate Hill. Immediately above the escarpment area is a formation of conglomerate hills.
· Limestone Hill. South of Lumbia are extensive rolling hill made up of limestone. A smaller limestone area is located on the right side of Bigaan River.
· Shale/ Sandstone Hill. West of the Lumbia airport is another sedimentary formation of shale/sandstone hills.
· Volcanic Hill or Mountain. On the farthest end of the city along the Misamis Oriental-Bukidnon boundary are rugged and steep hills and mountains of volcanic origin.
1.5 Soil Types
Cagayan de Oro soils are predominantly clayey. Other soil structures are sand, sulfaquent, loam, and clayey loam.
Soils, which are good for agricultural production, are San Manuel Loam and Bantog Clay. The Matima Clay and Umingan Clay Loam are lesser quality for agricultural production. Other soil types which do not have any agricultural value are hydrosol, beach sand and stony clay. Some of these soils are in rough mountain regions not suitable for exploitation; others are in lowland, which are suitable for resort and urban-related uses.
1.6 Climate and Rainfall
Climate in the Philippines has been described in terms of rainfall distribution that occur during the year, classified as follows: Type I, Type II, Type III, Type IV.
In 1999, rainfall particularly in Cagayan de Oro, belonged to Type IV. Rainfall is more or less evenly distributed throughout the year. This is also intermediate between the first and second types.
PAG-ASA records reveal the following:
… The average yearly total of rainfall is about 2,305 millimeters.
… The coldest temperature was in February 1999, which
recorded
17.6 C
… The hottest month, at 36.0 C, was July.
… The average wind run registered 1 to 2 m/sec.
