These strategies are core components ofLow Impact Development (LID)andgreen infrastructureapproaches for rainwater management:
"LID emphasizes... minimizing land disturbance, preserving vegetation, minimizing impervious cover..." These help reduce runoff volume and replicate the site's natural hydrology, improving rainwater management.

LEED Building Design and Construction: Homes is the rating system that applies to single-family homes, low-rise multi-family homes, and mid-rise multi-family homes1. It includes the ability to reduce point thresholds for LEED certification levels based on building size, as smaller homes tend to have lower environmental impacts than larger homes2. The point thresholds are determined by the size of the house compared to the number of bedrooms1.

The Location and Transportation (LT) category addresses the location and accessibility of a project site, as well as its impacts on transportation, land use, and community connectivity. One of the credits in this category is LT Credit: Surrounding Density and Diverse Uses, which rewards projects that are located in areas with high density and a variety of land uses, such as retail, residential, and civic facilities. This can reduce vehicle miles traveled, greenhouse gas emissions, and infrastructure costs, as well as promote walkability, livability, and social interaction. A new project that is built adjacent to a park with a trail leading to an urban business district qualifies for this credit by providing pedestrian access to diverse uses within a 1/2 mi. (0.80 km) walking distance1 . References: LEED v4 Green Associate Candidate Handbook1, LEED v4 BD+C Reference Guide

Open grid pavement, also known as permeable pavement, allows water to drain through it, reducing runoff and recharging groundwater supplies. It also tends to be lighter in color than traditional asphalt, which means it absorbs less heat from sunlight. This helps to reduce the urban heat island effect, which is a phenomenon where urban areas are significantly warmer than their rural surroundings due to human activities. References:

ASHRAE 55 defines thermal comfort by outlining acceptable indoor conditions for temperature, humidity, and air movement. This standard is essential for meeting LEED Indoor Environmental Quality requirements.
