Skabelund, Kansas State University Landscape Architecture / Regional & Community Planning Principal Investigator / Project Manager Konza Prairie near Manhattan, KS Flint Hills Ecoregion

2 Urban Stormwater Concerns Throughout Manhattan, urbanizing parts of Riley County, Kansas, and other urban areas, stormwater is typically sent quickly away from developed areas and straightpiped into drainageways, streams, rivers, and ponds. As a result of these and other land-use practices, riparian ecosystems in the Upper Kansas River Watershed continue to be severely degraded. Large amounts of groundwater are also pumped to the surface, and sprayed on lawns, gardens, and other landscapes. Very little water replenishes underground water reserves. What can we do to correct these bad habits?

3 Project Summary This collaborative design-build project engaged students, faculty, staff, and professionals in the task of considering ecologically sound ways to treat stormwater that falls on the Kansas State University (KSU) campus. In the process, two specific goals were achieved: 1) Designed and created a rain-garden along a selected area of Campus Creek to reduce stormwater run-off and improve water quality. 2) Demonstrated specific ways to address urban stormwater runoff to KSU administrators, staff, faculty, students, and visitors.

4 Educational Intent Engaging KSU administrators, staff, faculty, students, and local planning/design professionals is deemed essential if substantive changes in stormwater management are to occur on campus and in the larger community. This collaborative design/build demonstration project involved key stakeholders at KSU and other communities, raising their awareness of best practices, testing design ideas on the ground, and engaging those who influence stormwater management at KSU and beyond.

5 Primary educational goals: 1) Help students deepen their knowledge of both natural and human systems (building on lessons learned in Natural Systems & Site Analysis, Fluvial Systems, Construction I, II & III, Environmental Issues & Ethics, and Landscape Architecture Design courses); 2) Necessitate collaborative, interdisciplinary teamwork, and; 3) Require critical thinking about how conceptual design ideas are translated into construction drawings and functioning systems with a limited budget of time and money.

7 Learning from Precedents: water-sensitive site planning/design project DOE-Robb Williamson photo DOE-Robb Williamson photo Excerpted remarks by David W. Orr, Director of Oberlin's Environmental Studies Program, in Three years ago we began the effort to design a building for the Environmental Studies Program. We intended to create not just a place for classes but rather a building that would help to redefine the relationship between humankind and the environment one that would expand our sense of ecological possibilities. We began by asking: Is it possible even in Ohio to power buildings by current sunlight? Is it possible to create buildings that purify their own wastewater? Is it possible to build without compromising human and environmental heath somewhere else or at some later time? Sources: NASA (unlabled photos); Oberlin College (text & David Orr photo)

8 Water-sensitive site planning/design project ASLA 2004 award winner Roof water is collected in carved stone basins, then drains into a grated channel before cascading over a five-foot stone-faced retaining wall. The learning lab and auditorium buildings expand onto the courtyard, which is paved with stone, subtly-colored sandblasted concrete, and tile artifacts (historically manufactured in the watershed). Surrounding forest and meadows are pulled into the courtyard and onto building roofs.

A new parking lot integrates multiple functions: parking, water collection, and horticultural display. The lot includes an impervious asphalt roadway, with permeable asphalt parking bays off to the sides. A stormwater recharge bed lies under the entire lot. When it rains, water rapidly disappears through the permeable paving and into the underground basin where it infiltrates into the ground.

Level spreaders and vegetation infiltrate water into the soil. The project employs civil engineering without traditional expensive and destructive stormwater drainage systems and provides a wide range of shared community open space within a 167-acre preserve. Level Spreader slows runoff Stream Prairie Wetland Cell treats sewage Greenroof Restoring Native Ecosystems and Habitats Unbuilt areas are being restored to a pre-settlement landscape to minimize soil erosion and rebuild soil integrity, re-establish native plant & animal communities and encourage increased bio-diversity.

21 KSU Green Roof Design Fall 2007 Green roof designs were proposed for a handful of buildings on the K-State Campus in Manhattan, Kansas. Landscape Architecture students visited four constructed green roofs in Kansas City, Missouri; reviewed and discussed the literature related to green roof design, construction and management; and then selected one or more rooftops on which to design a green roof. They spent three weeks asking: What if? What might be? If here, how?
