On December 1, 2020, Public Law 35-110 was passed. This law amended §§ 1203, 1204, 1205, 1205.1, 1206, 1209(H), 1210, 1211, 1212, 1213, and 1214 Of Article 2, Chapter 1, Title 5, Guam Code Annotated, Relative to renewing the Guam Comprehensive Development Plan to encompass the principles of sustainability. In accordance with Public Law 35-110, the plan is named The Guåhan 2050 Sustainability Plan (G50SP).

The Guåhan 2050 Sustainability Plan is not simply a land use map—it is a living commitment to the people of Guam. It recognizes that every decision about where and how we build, protect, and invest has consequences for generations. By integrating environmental stewardship, economic opportunity, and cultural preservation, the plan charts a path that is both ambitious and grounded in community priorities.

Guam’s Choice for the Future

By 2050, Guam can be a place where vibrant villages, a prosperous economy, a thriving environment, and a celebrated culture reinforce one another—where development decisions respect the limits of our island, balance competing needs, renew our natural resources, ensure equity, and engage everyone in shaping the future. We face converging challenges: climate change bringing hotter days, rising seas, and stronger storms; global economic forces impacting tourism, defense, and local industries; rapid population and land use pressures from military expansion and urban growth; and cultural change that risks eroding CHamoru heritage and community life.

The Guåhan 2050 Sustainability Plan (G50SP) is Guam’s roadmap to meet these challenges. It was created through broad community engagement, guided by Public Law 35-110, and aligned with the United Nations Sustainable Development Goals.

Core Values and Principles

The G50SP is guided by five core principles that serve as a compass for all its policies:

Limits – Respect ecological and infrastructure thresholds.

Balance – Integrate environmental, economic, and cultural needs.

Renewal – Revitalize the built environment; restore degraded lands, waters, and heritage.

Equity – Ensure fairness in access to land, resources, and opportunity.

Engagement – Include all voices in decisions and implementation.

These principles are embedded within five thematic goals of the G50SP: Sustainable Communities, Prosperous Economy, Thriving Environment, Vibrant Culture, and Village Sustainability. Each goal has a dedicated chapter in the plan, with policies and objectives that respond to Guam’s unique challenges and opportunities.

Big Ideas and Policies

The G50SP’s land use policy framework is the backbone of the plan. It organizes many hundreds of interrelated policies across the five thematic chapters into a coherent system designed to guide development, conservation, and infrastructure investments through 2050. At its core, the framework:

Sets clear spatial priorities – Urban growth is directed to areas with existing infrastructure, while rural landscapes, watersheds, aquifers, and cultural heritage sites are conserved through protective zoning and overlays. Green infrastructure and coastal resiliency are prioritized by plan policies.

Integrates hazard and climate data – Flood maps, sea level rise projections, and hazard overlays shape where and how building can occur, reducing long-term risk.

Connects land use to infrastructure – Development approvals are tied to the capacity and resilience of water, wastewater, stormwater, energy, and transportation systems.

Balances economic and cultural objectives – Policies encourage redevelopment of underused urban areas, support small business and eco-cultural tourism, and protect agricultural lands to strengthen food security.

Elevates village planning – Each village’s character, priorities, and needs are reflected in context-specific land use policies, ensuring growth supports rather than erodes local identity.

This integrated approach replaces fragmented, sector-by-sector decision-making with a shared, island-wide framework that still leaves room for village-level flexibility. By embedding environmental stewardship, cultural preservation, and economic opportunity into the same decision process, the framework helps avoid conflicts, streamline permitting, and ensure cumulative gains toward sustainability.

From Plan to Action – Integrated Governance for a Sustainable Guam

Turning the vision into reality will depend on how Guam governs its land and resources over time. The G50SP implementation will be coordinated by the Bureau of Statistics and Plans, supported by a Sustainability Plan Implementation Task Force. Actions are phased into short-term (2025–2030), mid-term (2030–2040), and long-term (2040–2050) horizons. The G50SP implementation roadmap emphasizes more integrated governance that is:

Coordinated – Aligning the actions of agencies responsible for planning, infrastructure, environment, and cultural heritage so decisions reinforce rather than conflict with one another.

Accountable – Assigning clear responsibility for outcomes, tracking performance against measurable indicators, and reporting results to the public, the Legislature, and village leaders.

Transparent – Making planning data, maps, and progress reports publicly accessible and understandable.

Inclusive – Engaging village mayors, the Municipal Planning Councils, cultural organizations, and residents—recognizing tribal and indigenous governance roles as equal partners in decision-making.

Adaptive – Reviewing policies regularly, learning from results, and updating approaches in response to new challenges, science, and community priorities.

This governance-centered approach ensures that land use planning is not a one-time exercise, but an ongoing process of balancing competing needs in a way that builds trust, reduces uncertainty, and strengthens Guam’s resilience. The G50SP is as much about how decisions are made as it is about what decisions are made, recognizing that strong institutions and sustained community partnerships are essential to securing the island’s shared future.

Ultimately, it will be up to the people of Guam, working together and with an enduring commitment to a common purpose, to realize the vision of a sustainable, equitable Guåhan for present and future generations.
