Coordination with PHIVOLCS for Fault Trace Delineation
- Developers and registered owners must coordinate with the Philippine Institute of Volcanology and Seismology (PHIVOLCS) for the precise identification and delineation of the fault traces.
- The delineation must be clearly shown on subdivision development plans.
Requirements for Application on Subdivision Plans
- Complex subdivision projects must submit a Site Development Plan signed by a licensed architect or engineer planner at an appropriate scale (1:1,000 to 1:5,000).
- The plan must show the proposed layout in relation to existing conditions, including fault trace markings as identified by PHIVOLCS.
- Final subdivision plans must include a topographic plan that clearly shows the Marikina Valley Fault Trace and other identified fault traces along with the mandatory five-meter buffer zones on either side of the fault lines.
Prohibition of Development Within the Five-Meter Easement
- No construction or development activities are allowed within the five-meter mandatory easement on both sides of the Marikina Valley Fault Trace and other fault traces recognized by PHIVOLCS.
- This restriction applies to all types of subdivision projects and residential condominium projects, ensuring consistent safety standards across land development activities.
Amendments to Specific Rules and Sections
- Rule I, Section 1, 11A-1: Added obligation to coordinate with PHIVOLCS for fault delineation on site development plans.
- Rule I, Section IIB-3: Inclusion of the topographic plan requirement showing the fault trace and easements.
- Rule V, Section 11 A-2: General prohibition on developments within the five-meter easement in subdivision design standards.
- Rule V, Section 12 C: Extension of the easement prohibition to residential condominium project area planning.
Legal and Administrative Implications
- The resolution imposes an obligatory buffer zone to reduce risks associated with fault movements.
- It integrates geological hazard assessment into urban planning and land development approval processes.
- Reinforces inter-agency cooperation between HUDCC, PHIVOLCS, and developers for safer land use.
Enforcement and Compliance
- The Housing and Land Use Regulatory Board (HLRB) exercises authority in approving subdivision plans ensuring compliance.
- Failure to observe the five-meter easement restriction may result in denial of permit applications and other legal consequences.
Signatories and Authority
- Resolution adopted by the Housing and Land Use Regulatory Board on August 17, 1992.
- Signed by key officials including the Acting Chairman of HUDCC and Commissioners of HLRB, reflecting high-level endorsement and binding effect.
