MARCH 31, 2010 PAGE 3

In 2008 this property was vacant, pending further development, when DST Systems had an idea: PLANT GARDENS.

Rain gardens would add beauty to

the site while helping manage storm

water runoff. Other gardens would be

used to grow food for the community’s

hungry, and to show people how to

plant similar gardens at home.

The concept evolved, embracing an inte-

grated approach to urban development

and resource management. 18Broadway

demonstrates and tests a wide range of

practical solutions for building and living

in a healthy environment.

AN OPPORTUNITY

DST Eco-Initiative Designed to Deliver Long-term Public BenefitDST “18 Broadway” Project

18 Broadway is a zero-impact, green initiative on a full city block, two blocks south of the Performing Arts Center straddling two urban neighborhoods – the Crossroads and West Side. The Project is a combined living laboratory and demonstration site for 17 green technologies in the Water, Food, Shelter and Energy sectors. Its high-profile location on a major downtown boulevard is an ideal location for achieving maximum exposure of the Project’s primary impact objectives:

1. Catalyst to stimulate, educate, and test new thinking in applied green technologies2. Alternative solution to Kansas City’s storm water overflow problem3. Compatibility of commercial development with environmental stewardship4. Replicable design for city-wide application5. City amenity with sustainable economic, social, and environmental benefits

Water – Project designers have devised a state-of-the-art network of rain gardens to integrate with Kansas City’s proposed “10,000 Rain Garden” solution to its Combined Overflow Control Problem. A series of storm water management systems, including rain gardens, purifies and reuses storm water that falls onto the site and is brought into the site from the surrounding streets. Each garden is a discrete eco-system, employing its own unique hydrological and phyto-remediation techniques to capture and purify approximately 1 million gallons of contaminated run-off annually, which represents 1% of the Turkey Creek basin runoff. Purified water is then re-circulated on site to irrigate community gardens and supply fresh water to the site’s future zero-energy townhomes.

Food – Community gardens comprise the ½-acre center portion of the Project site and serve as a hub for wholesome community activity. Fresh produce will be made available to local community food centers for families in need. DST is currently in discussions with Harvesters to provide 2 tons of fresh produce annually from 18 Broadway to its food banks.

Energy – All requisite electrical energy is generated on site using a combination of solar panels and photo-voltaics to achieve a zero-carbon footprint. Eco-fuel technologies which further diminish greenhouse gas emissions will complete the site’s alternative energy profile and will include the following: electric vehicle charging station using off-peak power from solar panels; charging station for compressed natural gas; Big Belly solar powered trash compactors; and glass recycling center.

Shelter – DST is in discussion with KCP&L about new net-zero energy townhomes that will demonstrate how green residential development can be energy self-sufficient and Integrated with conventional urban structures. A commercial building on the block can be used as a part of an integrated platform for making this site a micro-grid showcasing leading-edge energy efficiency strategies, from automated information systems and demand/response to renewable distributed energy that will actually push electric power back onto the electric utility grid.

The following pages provide detail of DST’s 18 Broadway Project as developed by Kansas City-based firms 360 Architects, Patti Banks Associates, and TapanAm Associates, Inc. A public-private partnership could replicate this DST Project throughout Kansas City, making our City a model of leading-edge green infrastructure development that delivers long-term benefit to the public and private sectors.

The site slopes diagonally from northwest to northeast. It has a wonderful promontory view from the top corner out over Kansas City’s Crossroads Art District and midtown beyond.

The upper plaza looks southeast over the Crossroads Art District. The container garden is just beyond the plaza. The raised bed terraces are just beyond the container garden and descend to the opposite corner of the site. The benches were made from recycled ipe from Planet ReUse and built by a local furniture craftsman. Wineberry DG will fill the recesses below the benches and a larger specimen tree will be planted in the open cut for plaza shade.

That’s enough to fill Lake Lotawana, twice. 18Broadway addresses the issue by adopting

nature’s approach. It captures and cleans storm water, including the pollutants it carries,

on site before it can overwhelm the sewer system. Implementing best practices in storm

water management, the project demonstrates how land can be developed to ensure the

quality of our watershed, conserve rainfall, and reduce the city’s estimated $2.4 billion

cost to repair its outdated sewer system.

FOLLOW THE RAINDROPNature manages rainfall by passing it through soil and vegetation, purifying it along the way. 18Broadway follows nature’s model. Storm water travels through an integrated system of rain gardens and swales that filter out contaminants.

Rainfall from Broadway enters storm planters, where it is cleaned and a small amount retained. The excess is directed through the sidewalk via covered channels into a rain garden.

Water entering from the Broadway planters and 19th Street trenches is cleaned and stored in a series of rain gardens. Excess water flows over weirs, or small dams, and cascades through the rain gardens.

Rainfall from 18th Street flows under the sidewalk via covered channels into the 18th Street swale.

Alley swales clean and convey water to the lower-most rain garden, which provides minor detention and helps regulate flow.

Rain that falls on the existing building rooftop flows to the 18th Street swale.

Curb bump-outs are swales that capture rainfall, filter it and release clean water while helping to control street traffic.

Rainfall from 19th Street flows under sidewalk trenches into rain gardens.

Water is directed to underground storage tanks through an intake at the lowest rain garden.

Water is stored underground and pumped for irrigation needs.

A view looking south along Broadway Boulevard from Broadway Plaza. Stormwater planters are located along Broadway to capture stormwater from the street and con-vey it into the site and rain gardens. In larger water events the stormwater planters are designed to concurrently return water back onto the street.

There are ten rain gardens that border the site on the west and south sides. The intent is to show a variety of rain gardens using drought tolerant and native species. The various types range in dominance from grasses to flowering and insect attracting. The consideration of Butterfly Milkweed is a result of Kansas City being on the Monarch Butterfly flyway. Below is a sample of the some of mixes one will find on site.

The rain gardens haven’t been planted, but the detention capabilities can be seen here during a heavy rainstorm. The total storage capacity of the site is 90,000 gallons.

more ways than dollars and cents. The gardens of 18Broadway bring people

18Broadway’s high production volunteer garden is productive eight months out of the year, since many beds are “turned” at least twice. For example, one bed may have spinach in the spring, tomatoes in the summer, and still another crop in the fall.

WHAT IF EACH CITY BLOCKRECYCLED WASTE?By keeping glass out of landfills and using it instead to make fiberglass insulation (here in Kansas City)

and new glass containers, much of the energy and labor—and all the raw materials that went into making

it— are recaptured. The result? Dramatic energy savings and reductions in air and water emissions.
