Intent

To assess site conditions before design to evaluate sustainable options and inform related decisions about site design.

Requirements

Complete and document a site survey or assessment1 that includes the following information:

Topography.

  • Contour mapping
  • Unique topographic features
  • Slope stability risks

Hydrology.

  • Special Flood Hazard Areas (SPFHA) as determined by FEMA’s Flood Insurance Rate Map (FIRM) (or local equivalent for projects outside the U.S.)
  • Delineated natural water bodies wetlands, lakes, streams, and shorelines (refer to U.S. EPA’s Clean Water Act or local equivalent for projects outside the U.S.)
  • Rainwater collection and reuse opportunities
  • Impervious and pervious surfaces within the site boundary

Climate.

  • Solar exposure and shading opportunities
  • Heat island effect potential
  • Seasonal sun angles
  • Prevailing winds
  • Average monthly precipitation and temperature ranges

Vegetation.

  • Primary vegetation types
  • Greenfield area
  • Significant tree mapping
  • Federal or state threatened or endangered species lists; for projects outside the U.S., International Union for Conservation of Nature (IUCN) Red List of Threatened

Species

  • Invasive plant species listed by regional, state, or federal entities
  • EPA Level III ecoregion description (or local equivalent)

Soils.

  • Natural Resources Conservation Service soils delineation (or local equivalent for projects outside the U.S.)
  • U.S. Natural Resources Conservation Service (or local equivalent for projects outside the United States) prime farmland, unique farmland, farmland of statewide importance, or farmland of local importance
  • Healthy soils
  • Previous development
  • Disturbed soils

Human use.

  • Views
  • Adjacent transportation infrastructure, bicycle network, and bicycle storage
  • Adjacent diverse uses
  • Construction materials with existing recycle or reuse potential

Human health effects.

  • Proximity of vulnerable populations
  • Adjacent physical activity opportunities
  • Proximity to major sources of air and water pollution

The survey or assessment should demonstrate the relationships between the site features and topics listed above and how these features influenced the project design; give the reasons for not addressing any of those topics.

What does it cost?

Cost estimates for this credit

On each BD+C v4 credit, LEEDuser offers the wisdom of a team of architects, engineers, cost estimators, and LEED experts with hundreds of LEED projects between then. They analyzed the sustainable design strategies associated with each LEED credit, but also to assign actual costs to those strategies.

Our tab contains overall cost guidance, notes on what “soft costs” to expect, and a strategy-by-strategy breakdown of what to consider and what it might cost, in percentage premiums, actual costs, or both.

This information is also available in a full PDF download in The Cost of LEED v4 report.
