LT Credit: High-Priority Site

High-priority sites are not just about location—they’re about impact: restoring, revitalizing, and reusing land that needs attention.

 What is the Intent of this Credit?

The goal is to:

👉 encourage development in high-priority areas
👉 revitalize communities and reduce environmental impact

💡 Why This Matters

Many sites already have:

  • existing infrastructure
  • historical or cultural value
  • environmental challenges (like contamination)

👉 Redeveloping these sites is better than building on greenfields

🧩 Three Compliance Options

🏛️ Option 1: Historic District + Infill Site

Requirement

👉 Locate the project:

  • within a historic district
  • AND on an infill site

❓ What is an Infill Site? (VERY IMPORTANT)

👉 A site where:

  • ≥75% of land area
  • within ½ mile (800 m) of project boundary
  • is previously developed

⚠️ Critical Clarification

  • Roads / rights-of-way → ❌ NOT counted
  • What matters → land beyond the road

🎯 Exam Must-Know

75% + ½ mile = Infill Site

💡 Why LEED rewards this:

  • strengthens existing communities
  • reduces sprawl
  • supports historic preservation

🌆 Option 2: Priority / Economically Distressed Areas

Requirement

👉 Locate the project in a qualified high-priority area

✅ Examples (You don’t need to memorize all, but recognize types)

  • EPA National Priorities List
  • Federal Empowerment Zone
  • Enterprise Community
  • Renewal Community
  • Low-Income Community (Treasury CDFI Fund)
  • HUD Qualified Census Tract or DDA
  • International equivalent programs

🎯 Exam Insight

This option is about:
👉 economic + social revitalization

☣️ Option 3: Brownfield Redevelopment

Requirement

👉 Locate the project on a:

👉 Brownfield site with contamination AND required remediation

❓ What is a Brownfield?

👉 A site where:

  • redevelopment is complicated by
  • presence or potential presence of contamination

⚠️ Key Requirement

👉 Contamination must be:

  • in soil or groundwater
  • AND identified by authority having jurisdiction

🔬 How is Contamination Identified? (HIGH PROBABILITY QUESTION)

  • Phase I Environmental Site Assessment
  • Phase II Environmental Site Assessment
  • Local equivalent
  • Environmental expert evaluation

❗ Important Limitation

👉 This credit applies ONLY to:

  • soil contamination
  • groundwater contamination

🚫 What Does NOT Count

  • asbestos in buildings
  • interior hazardous materials
  • demolition debris

👉 These are NOT valid for this credit

🎯 Exam Trap

“Contamination inside building = qualifies”
👉 ❌ Incorrect

 

🏗️ Remediation Requirement

If NOT yet remediated:

👉 Project must:

  • obtain confirmation from authority
  • follow required remediation plan
  • complete remediation to their satisfaction

If ALREADY remediated:

👉 Can still qualify if:

  • proper documentation is provided

⚠️ Critical Rule (Very Testable)

👉 If ANY part of the site is contaminated:

➡️ Entire LEED project boundary = considered contaminated

🧠 Where People Get Confused

❌ Misconception 1:

“Any contaminated site qualifies”

👉 No
Must be:

  • soil or groundwater contamination
  • officially recognized
  • remediation required

❌ Misconception 2:

“Interior contamination counts”

👉 No
Only soil + groundwater qualify

❌ Misconception 3:

“Infill just means urban site”

👉 No
Must meet:

  • 75% previously developed
  • within ½ mile
