In LEED terminology, a previously undeveloped site is one that has not been significantly altered by human activity, such as by construction or paving. An improved park with manicured landscaping and paved playground areas would be considered previously developed because it has been altered from its natural state. The other options, involving areas with substantial building footprints, also indicate previously developed land. Therefore, the area described in option D, despite being relatively small, is the correct choice as it reflects human alteration of the land, making it a developed site.

Donating salvaged lumber to a local community organization for use in building low-income housing contributes toward the Green Infrastructure and Buildings (GIB) Credit for Recycled and Reused Infrastructure. This credit encourages the reuse of materials to reduce waste and the demand for new materials, thereby lowering the environmental impact associated with material production and disposal. By donating salvaged lumber, the project supports the goals of recycling and reuse, which aligns with the credit's intent.

The Natural Resources Conservation Service (NRCS), a division of the United States Department of Agriculture (USDA), is the agency responsible for identifying prime and unique soils in agriculture and other associated industries. Prime farmland is land that has the best combination of physical and chemical characteristics for producing food, feed, forage, fiber, and oilseed crops. The identification of such soils is crucial for ensuring that land development projects do not unnecessarily disturb valuable agricultural land. LEED credits often require consultation with NRCS or its local equivalent to verify the presence of prime soils and to make informed decisions about land use.

For the Green Infrastructure and Buildings Credit related to Renewable Energy Production, wind energy is an eligible source of renewable energy. LEED recognizes wind energy as a clean and sustainable energy source that contributes to reducing greenhouse gas emissions. Other options, such as ground-source heat pumps, are not considered renewable energy sources because they typically rely on electricity or other energy sources to operate. Combustion of municipal solid waste and forest biomass waste may produce energy, but they are not categorized as renewable in the context of LEED's Renewable Energy Production credit.

To meet the Minimum Program Requirements (MPR) for a LEED for Neighborhood Development (LEED ND) certification, a project must encompass a minimum area that includes at least one habitable building. The MPRs are designed to ensure that the project is of a scale that supports neighborhood-level sustainability strategies. A site with an area of 1,200 acres (465.62 hectares) containing five habitable buildings meets these requirements. The presence of multiple habitable buildings aligns with the intent of the LEED ND program to develop sustainable, vibrant neighborhoods.

For a LEED for Neighborhood Development project, having access to a local utility that supplies renewable energy to the site significantly contributes to earning certification. This contextual attribute aligns with LEED’s emphasis on sustainable energy use, which is critical for reducing the environmental impact of the neighborhood. The availability of renewable energy directly supports credits related to Green Infrastructure and Buildings, such as those for Renewable Energy Production, and enhances the overall sustainability of the project.

To determine if a project qualifies for the Green Infrastructure and Buildings Credit related to Wastewater Management in LEED for Neighborhood Development (LEED-ND), the most relevant piece of information is theaverage amount of annual wastewater generatedby the project. This metric is essential because the credit focuses on minimizing the impact of wastewater on the environment, primarily through strategies such as reducing the volume of wastewater produced, treating wastewater on-site, and reusing treated wastewater.

Wastewater Generation and Management:The LEED-ND rating system encourages the efficient management of wastewater to minimize its environmental impact. Specifically, the Green Infrastructure and Buildings Credit requires that a project demonstrates effective strategies for managing and reducing the volume of wastewater generated annually. This involves calculating the total averageamount of wastewater generated by the community and assessing how much of it can be treated and reused on-site.

Credit Requirements:To earn the Wastewater Management credit, projects must typically show that they have reduced the amount of wastewater generated by at least 25% compared to baseline conditions or that they treat and reuse a significant portion of their wastewater on-site. This necessitates an accurate estimation of the average annual wastewater production to determine the appropriate strategies and technologies for meeting the credit's objectives.

Supporting Strategies:Projects may employ various methods to achieve this, including installing efficient plumbing fixtures, recycling graywater, using natural treatment systems (like constructed wetlands), or connecting to high-efficiency municipal treatment facilities. However, all these strategies hinge on an understanding of the total wastewater volume generated, making this the most critical data point.

The LEED Reference Guide for Neighborhood Development (LEED ND) provides comprehensive criteria and methodologies for calculating the average wastewater generation and determining credit eligibility.

TheGreen Infrastructure and Buildingssection of the LEED v4 for Neighborhood Development rating system further outlines the specific requirements and point allocations for wastewater management strategies.

This detailed assessment is crucial in ensuring that a project can meet the sustainability goals required for LEED certification under the Green Infrastructure and Buildings Credit for Wastewater Management.

To earn a total of two points under the Neighborhood Pattern and Design Credit for Community Outreach and Involvement, after achieving the requirements for Option 1: Community Outreach, a project team can establish ongoing means for communication between the developer and the community. This action demonstrates a long-term commitment to involving the community in the development process and ensuring that their concerns and input continue to be addressed as the project progresses.

Community Outreach and Involvement Credit:This credit aims to ensure that the project is developed with input from the community, fostering transparency and collaboration between developers and residents. Achieving this credit not only helps in gaining community support but also improves the overall sustainability and livability of the project.

Establishing Ongoing Communication:While the initial community outreach typically involves workshops or meetings to gather input during the preliminary design phase, establishing ongoing communication channels ensures that the community remains informed and engaged throughout the development process. This could include regular newsletters, dedicated websites, or community liaison officers.

Benefits of Ongoing Communication:Continuous communication helps address any issues or concerns that may arise during construction or after the project is completed. It also allows the developer to update thecommunity on progress, gather feedback on any changes, and maintain a positive relationship with the neighborhood.

The LEED Reference Guide for Neighborhood Development details the requirements for achieving points under the Community Outreach and Involvement credit, including the benefits of establishing ongoing communication.

These explanations provide a thorough understanding of how specific project features can contribute to earning LEED-ND credits and meeting sustainability goals.

To make the 400-acre (161-hectare) site eligible for LEED for Neighborhood Development certification, rezoning the project for higher density is a critical initial step. LEED for Neighborhood Development promotes higher-density development as a way to reduce land consumption, preserve open space, and create more sustainable, walkable communities. The current zoning of two dwelling units per acre (five DU/hectare) may be too low to meet the prerequisites or credit requirements for density in LEED ND. By increasing the density through rezoning, the developer can better align the project with LEED ND goals and increase the likelihood of achieving certification.
