Warehouses-NC-v4 LTc2: Sensitive land protection

  • Avoid wetlands and other sensitive land

    This credit is particularly achievable for projects without wetlands or water bodies present onsite. If your project is locating on previously developedAltered by paving, construction, and/or land use that would typically have required regulatory permitting to have been initiated (alterations may exist now or in the past). Land that is not previously developed and landscapes altered by current or historical clearing or filling, agricultural or forestry use, or preserved natural area use are considered undeveloped land. The date of previous development permit issuance constitutes the date of previous development, but permit issuance in itself does not constitute previous development. land, Option 1 is straightforward to pursue. 

    The requirements get more complex if your project pursues Option 2. Under this option, you’ll need to avoid developing on various sensitive land types as outlined in the credit requirements. However, teams may make some improvements within wetland and water body buffers in order to enhance appreciation and enjoyment by all building users. The credit language includes a list of improvements that are considered minor and acceptable.

    What’s New in LEED v4

    • USGBC revised the floodplain limitations and now references the “flood hazard area shown on a legally adopted flood hazard map,” rather than the 100-year floodplain. Instead of being at 5 feet or more above the 100-year floodplain, you must now avoid the flood hazard area.
    • The required buffer zone around a body of water has increased from 50 feet (15 m) to 100 feet (30 m).
    • The wetland buffer has been reduced from 100 feet (30 m) to 50 feet (15 m).
    • The requirements for sensitive habitat have been expanded to include species and ecological communities classified by NatureServe, local wildlife agencies, and their equivalents for projects outside the U.S. or outside of areas with NatureServe data.
    • The credit now includes a list of permitted minor improvements in wetlands and buffer zones around bodies of water.

    FAQs

    If we pursue Option 1 do we have to honor the water body buffer of 100 feet and the flood hazard zones?

    No. Option 1 is simply to use a previously developed siteA site that, prior to the project, consisted of at least 75% previously developed land.. If your project qualifies for Option 1, you are not bound by the buffers included in Option 2. This is similar to previous versions of LEED.

  • LT Credit 2: Sensitive land protection

    Intent

    To avoid the development of environmentally sensitive lands and reduce the environmental impact from the location of a building on a site.

    Requirements

    Option 1.

    Locate the development footprintThe total land area of a project site covered by buildings, streets, parking areas, and other typically impermeable surfaces constructed as part of the project. on land that has been previously developedAltered by paving, construction, and/or land use that would typically have required regulatory permitting to have been initiated (alterations may exist now or in the past). Land that is not previously developed and landscapes altered by current or historical clearing or filling, agricultural or forestry use, or preserved natural area use are considered undeveloped land. The date of previous development permit issuance constitutes the date of previous development, but permit issuance in itself does not constitute previous development..

    OR

    Option 2.

    Locate the development footprint on land that has been previously developed or that does not meet the following criteria for sensitive land:

    • Prime farmland. prime farmland, unique farmland, or farmland of statewide or local importance as defined by the U.S. Code of Federal Regulations, Title 7, Volume 6, Parts 400 to 699, Section 657.5 (or local equivalent for projects outside the U.S.) and identified in a state Natural Resources Conservation Service soil survey) or local equivalent for projects outside the U.S.). [Canada ACP: Prime Farmland]
    • Floodplains: a flood hazard area shown on a legally adopted flood hazard map or otherwise legally designated by the local jurisdiction or the state. For projects in places without legally adopted flood hazard maps or legal designations, locate on a site that is entirely outside any floodplain subject to a 1% or greater chance of flooding in any given year. [Europe ACP: Flood Plains]
    • Habitat: Land that is identified as habitat for the following:
      • species listed as threatened or endangered under the U.S. Endangered Species Act or the state’s endangered species act [Europe ACP: Habitat], or
      • species or ecological communities classified by NatureServe as GH (possibly extinct), G1 (critically imperiled), or G2 (imperiled), or
      • species listed as threatened or endangered specifies under local equivalent standards (for projects outside the U.S.) that are not covered by NatureServe data.
    • Water bodies: Areas on or within 100 feet (30 meters) of a water body, except for minor improvements.
    • Wetlands: Areas on or within 50 feet (15 meters) of a wetland, except for minor improvements.

    Minor improvements within the wetland and water body buffers may be undertaken to enhance appreciation of them, provided such facilities are open to all building users. Only the following improvements are considered minor:

    • Bicycle and pedestrian pathways no more than 12 feet wide (3.5 meters), of which no more than 8 feet (2.5 meters) may be impervious;
    • Activities to maintain or restore native natural communities and/or natural hydrology;
    • One single-story structure per 300 linear feet (90 linear meters) on average, not exceeding 500 square feet (45 square meters);
    • Grade changes necessary to ensure public access;
    • Clearings, limited to one per 300 linear feet (90 linear meters) on average, not exceeding 500 square feet (45 square meters) each;
    • Removal of the following tree types:
      • Hazardous trees, up to 75% of dead trees
      • Trees less than 6 inches (150 millimeters) diameter at breast height
      • Up to 20% of trees more than 6 inches (150 millimeters) diameter at breast height with a condition rating of 40% or higher.
      • Trees under 40% condition rating

        The condition rating must be based on an assessment by an arborist certified by the International Society of Arboriculture (ISA) using ISA standard measures, or local equivalent for projects outside the U.S.
    • BrownfieldAbandoned, idled, or under used industrial and commercial facilities/sites who expansion, redevelopment, or reuse of which may be complicated by the presence or possible presence of a hazardous substance, pollutant, or contaminant. They can be in urban, suburban, or rural areas. EPA's Brownfields initiative helps communities mitigate potential health risks and restore the economic vitality of such areas or properties. remediation activities.

    Alternative Compliance Paths (ACPs)

    Canada ACP: Prime Farmland

    In Canada, if the project is mapped under the Canada Land Inventory (CLI), then prime farmland is land classified as Class 1, 2 or 3 of this inventory. For projects located on sites not mapped by this inventory, follow global guidance for local equivalents.

    Europe ACP: Flood Plains

    Projects in Europe may use the Directive 2007/60/EC definition of floods with a medium probability (likely return period ≥ 100 years).

    Europe ACP: Threatened and Endangered Species

    Projects in Europe may use the Natura 2000 network of protected areas and the European Red List.

    SITES-LEED Equivalency

    This LEED credit (or a component of this credit) has been established as equivalent to a SITES v2 credit or component. For more information on using the equivalency as a substitution in your LEED or SITES project, see this article and guidance document.
