28 Landscape Architect and Specifier News Designers should also create water areas with the public in mind and limit access to gently sloping bank areas around water features by adding natural screens and barriers while allowing public access where it can be controlled or monitored by park staff. Hunter's Point South achieves this level of safety with specific trails that lead pedestrians around water areas, and with its boat-like viewing platform that allows park-goers to see the river without getting too close to areas that might be flooded during high tide. Stormwater Mitigation in Parks The NRPA, in its Green Infrastructure Resource Guide, lists a few different ways to manage stormwater in parks. These include bioretention, bioswales, constructed wetlands and more. Hunter's Point South Park mainly relies on constructed wetlands for stormwater runoff. However, designers should consider several different sustainable techniques when considering a stormwater-resilient park. The NRPA recommends analyzing a park's location and context before incorporating green stormwater infrastructure. Not every park could support every type of stormwater mitigation system, and it is important to find the right fit in order to create the most sustainable park possible in a specific location. A Sustainable Guide Some sustainability-based design standards that the Hunter's Point South Park maintains are: designing higher than one thinks flood waters could possibly reach, making it difficult, but not impossible, for flood water to get into the park area and making it easy for water to flow back into bodies of water, but not into sewers. For areas that are in dire need of stormwater mitigation in their infrastructure, these design ideas could change the way cities recover when a huge hurricane or rainwater event hits. Conclusion Between soft barriers and purposefully flooded wetlands, Hunter's Point South Park exemplifies green stormwater infrastructure that has been proven to combat flooding and stormwater damage. Using the park as a guide and with the aid of several government and association resources, park designers may be able to implement storm resilient aspects into parks around the country.
