LT Credit: High-Priority Site
High-priority sites are not just about locationโtheyโre about impact: restoring, revitalizing, and reusing land that needs attention.
ย What is the Intent of this Credit?
The goal is to:
๐ encourage development in high-priority areas
๐ revitalize communities and reduce environmental impact
๐ก Why This Matters
Many sites already have:
- existing infrastructure
- historical or cultural value
- environmental challenges (like contamination)
๐ Redeveloping these sites is better than building on greenfields
๐งฉ Three Compliance Options
๐๏ธ Option 1: Historic District + Infill Site
Requirement
๐ Locate the project:
- within a historic district
- AND on an infill site
โ What is an Infill Site? (VERY IMPORTANT)
๐ A site where:
- โฅ75% of land area
- within ยฝ mile (800 m) of project boundary
- is previously developed
โ ๏ธ Critical Clarification
- Roads / rights-of-way โ โ NOT counted
- What matters โ land beyond the road
๐ฏ Exam Must-Know
75% + ยฝ mile = Infill Site
๐ก Why LEED rewards this:
