Here is my second installment in the comparative discussion of Atlantic Yards and a similar development project I pursued in school. You can see the part 1 here.Water TreatmentIn our academic proposal, we considered what to do with waste water and stormwater runoff. For dealing with sewage, we proposed the implementation of a Living Machine.Living Machine DiagramDiagram of living machineImage of Living MachineImage of aerobic treatment tanksAlthough not common in urban situations, developments are being made in this earth friendly waste treatment system. Due to its urban location, AY will likely be treating it’s sewage like the rest of the area (and most municipalities across the country) – by tapping into the existing sewer system.A summary of the significance of stormwater runoff here and A fairly technical summary of a variety of stormwater treatment practices can be found here.In our proposal, we incorporated swales (and here) and green roofs to keep stormwater runoff out of the combined sewer.What a swale looks likeSwale use Image of swale Diagram of effective use of swaleGreen roofs are becoming more and more popular as a way to mitigate stormwater runoff and reduce the urban heat island effect, thus reducing cooling loads for buildings.Chicago City Hall Green RoofChicago City Hall green roofGreen roof sectionSection of one type of green roof systemIn many new (particularly suburban) developments, this is how stormwater is detained:Stormwater pondStormwater detention “pond”FCRC has been asked to manage the stormwater runoff on-site. More traditional stormwater retention basins and detention ponds are planned, as well as the re-use of storm water on site for watering purposes. Green roofs are also planned throughout. The detailed appendix pertaining to infrastructure impact can be found here.Watch out for more installments…
