Sustainable Elements The housing authority set the bar high on sustainability, for both the infrastructure it would install to the homes and the systems they would support. It paid special attention to stormwater by retaining more water on the site to filtrate through to the ground water. Porous pavements are put to use for sidewalks and other hard surfaces, but the primary tools incorporated into the design are bioswales instead of curb and gutter. “The idea is the streets slant to one side and the water goes through curb cuts into bioswales, where it gets cleaned by the soil,” Phillips said. Strategically placed perforated pipe is installed several feet below grade to drain off excess water to keep the soils from becoming saturated. “Some will make its way to a storage pond and slowly be released into a salmon-bearing creek,” Phillips said. A storm sewer system was also designed into the initial plans. “It’s a back up system. In a few years, we may not even put that in,” Phillips said. Channeling stormwater from the building to the bioswales and design of porous pavements was the challenge faced by Cindy Wellborn, a civil engineer with David Evans and Associates, Inc., which provides engineering services for its sister company, Devland Inc. Her solution was to create conveyance furrows away from the homes, and landscaped with plants and rock. “In order to disperse as much of the runoff as we could, I used dispersal trenches and gravel level spreaders, so it would not be a concentrated flow, less energy and would be spread out over a greater area,” she said. Another tool was the use of yard drains that linked to the underground system of perforated pipe. For driveways and patios, she used pavers to take advantage of their aesthetic value while still allowing water to drain through. Builders like Devland were given a set of overall “green” criteria to use in Meet intuitive technology. t BaySaver Technologies, our engineers are known for simplifying designs and throwing a little common sense into the mix to help solve your stormwater treatment problems.
