LT Credit: High-Priority Site

High-priority sites are not just about locationโ€”theyโ€™re about impact: restoring, revitalizing, and reusing land that needs attention.

ย What is the Intent of this Credit?

The goal is to:

๐Ÿ‘‰ encourage development in high-priority areas
๐Ÿ‘‰ revitalize communities and reduce environmental impact

๐Ÿ’ก Why This Matters

Many sites already have:

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

๐Ÿ‘‰ Redeveloping these sites is better than building on greenfields

๐Ÿงฉ Three Compliance Options

๐Ÿ›๏ธ Option 1: Historic District + Infill Site

Requirement

๐Ÿ‘‰ Locate the project:

  • within a historic district
  • AND on an infill site

โ“ What is an Infill Site? (VERY IMPORTANT)

๐Ÿ‘‰ A site where:

  • โ‰ฅ75% of land area
  • within ยฝ mile (800 m) of project boundary
  • is previously developed

โš ๏ธ Critical Clarification

  • Roads / rights-of-way โ†’ โŒ NOT counted
  • What matters โ†’ land beyond the road

๐ŸŽฏ Exam Must-Know

75% + ยฝ mile = Infill Site

๐Ÿ’ก Why LEED rewards this:

  • strengthens existing communities
  • reduces sprawl
  • supports historic preservation

๐ŸŒ† Option 2: Priority / Economically Distressed Areas

Requirement

๐Ÿ‘‰ Locate the project in a qualified high-priority area

โœ… Examples (You donโ€™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

๐ŸŽฏ Exam Insight

This option is about:
๐Ÿ‘‰ economic + social revitalization

โ˜ฃ๏ธ Option 3: Brownfield Redevelopment

Requirement

๐Ÿ‘‰ Locate the project on a:

๐Ÿ‘‰ Brownfield site with contamination AND required remediation

โ“ What is a Brownfield?

๐Ÿ‘‰ A site where:

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

โš ๏ธ Key Requirement

๐Ÿ‘‰ Contamination must be:

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

๐Ÿ”ฌ How is Contamination Identified? (HIGH PROBABILITY QUESTION)

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

โ— Important Limitation

๐Ÿ‘‰ This credit applies ONLY to:

  • soil contamination
  • groundwater contamination

๐Ÿšซ What Does NOT Count

  • asbestos in buildings
  • interior hazardous materials
  • demolition debris

๐Ÿ‘‰ These are NOT valid for this credit

๐ŸŽฏ Exam Trap

โ€œContamination inside building = qualifiesโ€
๐Ÿ‘‰ โŒ Incorrect

ย 

๐Ÿ—๏ธ Remediation Requirement

If NOT yet remediated:

๐Ÿ‘‰ Project must:

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

If ALREADY remediated:

๐Ÿ‘‰ Can still qualify if:

  • proper documentation is provided

โš ๏ธ Critical Rule (Very Testable)

๐Ÿ‘‰ If ANY part of the site is contaminated:

โžก๏ธ Entire LEED project boundary = considered contaminated

๐Ÿง  Where People Get Confused

โŒ Misconception 1:

โ€œAny contaminated site qualifiesโ€

๐Ÿ‘‰ No
Must be:

  • soil or groundwater contamination
  • officially recognized
  • remediation required

โŒ Misconception 2:

โ€œInterior contamination countsโ€

๐Ÿ‘‰ No
Only soil + groundwater qualify

โŒ Misconception 3:

โ€œInfill just means urban siteโ€

๐Ÿ‘‰ No
Must meet:

  • 75% previously developed
  • within ยฝ mile
