DarkSky Vermont reviewed Vermont municipal plans for explicit dark-sky and outdoor-lighting policy language. This review is intended to help communities, planners, conservation commissions, development review bodies, and local advocates understand where Vermont plans already contain useful language, where policy gaps remain, and where model provisions may help inform future updates.
Across Vermont, municipal plans vary widely. Some contain strong and specific language addressing glare, light trespass, sky glow, energy waste, scenic character, wildlife impacts, or lighting design. Many contain only incidental references, and many do not yet address outdoor lighting explicitly at all. This review is meant to provide a practical statewide picture of that landscape.

What the Ratings Mean
5 — Strong fully surveyed model
The plan contains especially strong, specific, and policy-relevant language, and was documented as one of the clearest model examples in the survey.
4 — Strong indexed-text benchmark
The plan contains strong and fairly specific dark-sky or lighting language identifiable from indexed-text review, but was not documented as one of the top fully excerpted model examples.
3 — Moderate
The plan contains recognizable policy language on lighting impacts or controls, but it is limited in scope, specificity, or implementation detail.
2 — Weak / incidental
The plan contains only passing, vague, or incidental references related to lighting, scenery, energy use, or similar concerns, without meaningful policy direction.
1 — No explicit policy found
No explicit dark-sky or outdoor-lighting policy language was found, or the source plan could not be verified from the available materials.

What This Review Shows
The statewide results suggest that most Vermont municipal plans still do not contain clear, specific dark-sky or outdoor-lighting policy language. At the same time, a smaller but important group of municipalities have already adopted language that can serve as useful examples for others. The review suggests not only that explicit dark-sky language remains uncommon, but also that plan language is uneven and inconsistent across regions, pointing to an important opportunity for greater coherence in municipal planning.
That matters because municipal plans help establish policy direction. Clear plan language can support later work on bylaws, subdivision standards, site plan review, capital planning, public facility upgrades, scenic resource protection, wildlife protection, and energy-saving measures. Where plans are silent, those next steps are often harder to justify or coordinate. Regional Planning Commissions are well positioned to help municipalities incorporate clearer, more consistent language on outdoor lighting, glare, scenic character, habitat impacts, and energy waste while still adapting that language to local conditions. A more coherent regional approach could help towns avoid starting from scratch and support more effective follow-through in bylaws, subdivision regulations, capital planning, and public facility decisions.
This review also shows that Vermont already has workable examples. Communities do not need to start from scratch. Stronger language already exists in some plans, and those examples can help other municipalities adopt practical, locally grounded approaches that reduce glare, light trespass, sky glow, and unnecessary lighting costs without sacrificing safety or function. The next step is to build on those examples to develop a Vermont best-practice model for municipal plan language—one that can support greater consistency across regions while still allowing towns to adapt it to local conditions.
Method Note
This review examined Vermont municipal plans for explicit dark-sky or outdoor-lighting language. Ratings reflect the strength and specificity of language found in the plans themselves. They do not necessarily capture stronger provisions that may appear in zoning bylaws, subdivision regulations, ordinances, capital budgets, design standards, or other local regulations and practices.

Model Language and Next Steps
DarkSky Vermont is using this review to identify:
- strong municipal examples already in use in Vermont
- opportunities for improved plan language
- communities that may benefit from model policy guidance
- practical next steps for towns, villages, and regional partners
If your municipality is updating its plan and would like to strengthen language on outdoor lighting, glare, scenic character, wildlife impacts, or dark skies, see our Municipal Policy Guidance page for examples and recommendations.
