|Green Roof on the Effluent Filtration Building|
The plants are sedum, alliums, and euphorbia, selected for their ability to withstand drought, wind and sun. They have shallow root structure, making them ideal for roof landscaping where a deep soil is not possible. The plants also provide many months of flowering blooms.
Green roofs reduce urban heat from roof top reflections, reduce stormwater run-off, absorb air pollution, protect the roof from UV ray degradation, provide a natural habitat for birds and small animals, reduce the heat load to the building in the summer and provide additional insulation in the winter.
The next goal is to install a green roof on the new Ultraviolet Disinfection Facility, a 2,000 square foot surface, for an estimated cost of $35,000. This project is scheduled for fall 2012. The project construction manager is Arcadis and engineers are Greeley and Hansen.
