Which of thefollowing would meet the requirements of an infill site?

The requirement for an infill site under LEED® Neighborhood Development is that at least 75% of the site’s boundary must border parcels that are individually at least 50% previously disturbed, and in aggregate, at least 75% of the boundary must be adjacent to previously disturbed parcels.This criterion supports the redevelopment of previously developed land and helps in reducing urban sprawl by encouraging the use of already impacted sites.

Infill Development:Infill development refers to the practice of developing vacant or underused parcels within existing urban areas that are already largely developed. LEED-ND promotes infill development as it typically results in more efficient land use, reduces the need for new infrastructure, and supports the revitalization of existing communities.

Previously Disturbed Parcels:A "previously disturbed" parcel refers to land that has been altered by previous development or human activities, making it more suitable for redevelopment without contributing to the loss of greenfield sites (undeveloped land).

Boundary Criteria:The specific requirement that 75% of the project’s boundary borders disturbed parcels ensures that the site is surrounded by areas that have already experienced some level of development. This aligns with LEED-ND’s goals of encouraging sustainable development patterns that optimize land use within existing urbanized areas.

The LEED-ND Reference Guide elaborates on the criteria for infill sites under the Smart Location & Linkage (SLL) category, particularly emphasizing the importance of reusing previously disturbed land.

TheLEED v4 Neighborhood Developmentdocumentation provides detailed definitions and examples to clarify what constitutes an infill site.
