Questions and Answers

A construction company is developing a site in accordance with LEED standards. Which of the following actions would be LEAST effective in fulfilling the requirements of the Site Management Policy prerequisite?

  • Implementing electronic spreader controls on de-icing equipment to ensure even distribution.
  • Using ammonia-based fertilizers to promote rapid plant growth during landscaping. (correct)
  • Replacing gasoline-powered lawnmowers with electric-powered alternatives to reduce air pollution.
  • Establishing a bi-weekly monitoring system for irrigation systems to detect and repair leaks.

A project team is aiming to achieve Credit 1: Site Management. They have already implemented erosion and sedimentation controls. To meet the requirements of this credit, what additional action is required?

  • Documenting existing site conditions and future improvement strategies for hydrology, vegetation and soils.
  • Establishing financial support for a land trust within 200 miles of the project site.
  • Limiting turf area to no more than 25% of the total vegetated area on the site. (correct)
  • Implementing strategies to manage runoff from 50% of impervious surfaces.

A development project seeks to achieve Credit 2: Protect or Restore Habitat, focusing on on-site restoration. Which scenario would be considered compliant without requiring active vegetation efforts?

  • An area covered with gravel and used for equipment storage.
  • An area designated for a community garden with diverse vegetable plants.
  • A managed lawn area used for recreational activities.
  • A naturally occurring rocky mountain area within the site. (correct)
