Geodetic Engineer in Cagayan Valley

Land surveying and Cagayan Valley

In Cagayan Valley, the November 2020 floods from Typhoon Ulysses pushed the Buntun Bridge gauge in Tuguegarao to more than 13 meters, with Magat Dam releases adding to the Cagayan River's flow. For a riverside lot, the title line and the water line are not the same thing.

In Isabela, the Northern Sierra Madre Natural Park (RA 9125) covers about 287,861 hectares of land across Ilagan, San Mariano, Palanan and other towns, and in Baggao the Agta hold an ancestral domain of about 38,750 hectares. In Batanes, RA 8991 makes the whole island group a protected area.

Common problems in Cagayan Valley

• Lots near the Sierra Madre park: In Ilagan, San Mariano or Palanan, it is advisable to ask the DENR office whether your lot sits inside the park or its buffer before you buy. A Geodetic Engineer's relocation survey fixes your corners so they can be plotted against that boundary.
• Riverside lots on the floodplain: After the 2020 floods along the Cagayan River, a lot beside the bank may look different on the ground than on paper. A relocation survey shows where your title line runs against the bank, which is a separate question from flood exposure.
• Titles near ancestral domains: For a parcel in Baggao or a Sierra Madre community, it helps to ask the NCIP whether an ancestral domain claim touches it before the survey.
• Building in Batanes: RA 8991 protects Ivatan heritage, including scenic, cultural, historical and archaeological features. For a lot in Basco, Sabtang or Itbayat, it is advisable to ask the protected area office what applies before drawing a building plan.
