that contain vegetation that is planted in engineered soil. The soil allows for the filtration and storage of stormwater, recharging groundwater supplies. Producing tree canopies is another aspect of green street design. Street trees with adequate draining allow the rainwater runoff to penetrate the soil and slow stormwater runoff. Street trees also reduce the effects of the urban heat island (see "Cool streets" below) by shading paved surfaces from heat, the environment remains cool. They also use evaporative cooling and can sequester carbon, improving air quality and reducing carbon emissions. Implementing green streets helps to reduce stormwater runoff while increasing the water quality and supply to the urban environment. Creating more resilience to climate change with a healthier community. Cool streets Cool streets aim to reduce the effects of the urban heat island (UHI). Traditional streets are made of dark impervious materials that absorb energy from the sun and create warmer surrounding temperatures, increasing emissions and stormwater temperatures. These surfaces create a demand for air conditioning to cool structures. Increased conditioning contributes to higher electricity needs, escalating the overall demand within a city. Hotter conditions drive the peak energy up during hot summer days, as conditioning, lights, and appliances contribute to the energy need. Overloading systems and energy grids can lead to blackouts. Power companies can implement controlled brownouts or blackouts during this time to reduce the overall outage time. Hotter conditions can harm human health, causing general discomfort, respiratory difficulties, heat cramps, exhaustion, and non-fatal heat stroke. Implementing green infrastructure and replacing dark impervious materials is a solution to cool the surrounding environment and stormwater runoff. Implementing green infrastructure such as rain gardens, planter boxes, and green parking can reduce the effects of the urban heat island. Reducing dark impervious surfaces with lighter-colored materials reduces air temperature as the street surface reflects solar energy. Cool streets assist in creating cooler communities for residents within them. Through reducing energy usage, increasing water quality, and decreasing emissions. Consequently, lower temperatures reduce both emissions and temperature. This means communities may have fewer temperature-related illnesses, and the temperature of stormwater runoff reduces its impact on aquatic life in receiving waters. These lighter surfaces are also more resistant to heat degradation, and their reflective properties allow for more visibility at night. An increase in reflectivity also contributes to the reduction of energy usage. Street lights can run a lower wattage bulb, reducing demand. Cool
