CHAPTER 8: ENRICH 248 Green Stormwater Infrastructure Increased stormwater runoff combined with more urban development trends in Cary introduces new opportuni es to address drainage and water quality concerns as well as expand biodiversity through green stormwater infrastructure, or GSI, techniques. The cumula ve impacts of expanding and maintain- ing GSI prac ces improve environmental resiliency and facilitate the more natural movement of rainwater within the built envi- ronment. These measures improve stormwater quality as well as mi gate runoff by providing infiltra on and reducing the flow and volume of water entering the drainage system. The use of GSI with redevelopment projects will also benefit areas built prior to exis ng stormwater regula ons. Trees and the Urban Canopy In shaping the future of Cary, there are many opportuni es to embrace a mul faceted approach to urban forestry that harmo- nizes human needs with environmental considera ons. Cary is commi ed to preserving mature trees through best prac ces in tree care while plan ng the next genera on, ensuring a well-maintained and adap ve urban tree canopy that offers a myriad of benefits. Cary has worked to ensure tree preserva on and plan ng is integrated into development projects as Cary con nues to densify. A comprehensive, stringent set of policies and codes regulate the plan ng, maintenance, and protec on of public and private trees. Environmentally, trees serve as natural air filters by capturing pollutants and releasing oxygen. They play a vital role in stormwater management and erosion control, as canopies intercept rainfall to reduce the impact on the ground, while roots help to absorb excess rainwater and stabilize the soil, maintaining the integrity of landscapes. Trees also increase biodiversity in urban and suburban areas by providing habitats for wildlife. Having a diverse range of tree species promotes ecological balance and allows for natural interdependencies that contribute to a healthier environment and predator/prey rela- onships that can serve as natural pest control. The economic benefits of green infrastructure include temperature regula on, as the cooling effect reduces the urban heat island effect and makes buildings and neighborhoods more comfortable, thus reducing the burden on electricity. A well-maintained urban tree canopy also enhances property values, a racts businesses and tourism, and adds to the beauty and aesthe c appeal of Cary – promo ng physical and mental well-being. Finally, trees absorb and store carbon dioxide, contribu ng to carbon sequestra on and helping to mi gate climate change through the reduc on of greenhouse gas emissions. Cary owns and maintains a number of lakes and dams. These bodies of water serve mul ple func ons: flood protec on, water quality improvement, recrea on, wildlife habitat, and aesthe cs.
