Key Concepts of Subdivision Surveys

  • Subdivision Surveys: Essential for land development; ensures legal compliance and accurate division into smaller parcels.

  • Key Principles of Subdividing Land:

    • Legal Boundaries and Ownership
    • Proper Land Measurement (Surveying)
    • Zoning and Land Use Regulations
    • Infrastructure Planning
    • Environmental Laws Compliance
    • Government Agency Approvals

  • Regulatory Framework: Governed by Section 98 of DAO 2010-13, ensuring proper documentation, accuracy, and adherence to regulations.

  • DAO 2010-13 Overview: Issued by DENR of the Philippines, covers:

    • Standardized Land Surveys
    • Subdivision Survey Regulations
    • Accuracy and Validation
    • Compliance with Legal Requirements
    • Environmental Considerations

  • Types of Subdivision:

    • Simple Subdivision:
    • Minimal infrastructure changes
    • Quicker approval, fewer permits
    • Lower costs
    • Common for family divines and small sales.

  • Common Subdivision Cases:

    1. Dividing an area into two parts by a line between points.
    2. Dividing by a line through a point in a given direction.
    3. Cutting off an area by a line running through a given point.
    4. Cutting off an area by a line with an assigned direction.

  • Geometric Application: The subdivision may involve geometry and trigonometry for lines and distances.

    • Example Problem: Determine length of a dividing line and distances from dividing line to adjacent areas using line bearings and distances.
