DST Eco-Initiative Designed to Deliver Long-term Public Benefit DST “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 technologies Alternative solution to Kansas City’s storm water overflow problem Compatibility of commercial development with environmental stewardship Replicable design for city-wide application 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.

Broadway Plaza 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.

6.4 BILLION

GALLONS OF COMBINED STORM WATER AND WASTEWATER

OVERFLOW INTO

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 RAINDROP Nature 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.

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

In the spirit of Kansas City’s 10,000 Rain Gardens initiative, 18Broadway has several rain gardens. Long grasses and native and drought-tolerant plants hold water and act as filters cleaning the water as it flows on its journey.

There will be 77,000 native plants in the ground when 18 Broadway is complete

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.

GET LESS? Our food can travel 2,000 miles or more from farm to plate. We pay for that in more ways than dollars and cents. The gardens of 18Broadway bring people closer to fresh food that tastes better and is better for us.

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.

HOW CAN A CITY BLOCK FEED PEOPLE IN NEED? Fresh produce from the volunteer-tended 18Broadway garden is donated to Harvesters Community Food Network of Kansas City.

HOW CAN A CITY BLOCK RECONNECT PEOPLE TO FOOD? The agricultural gardens at 18Broadway show how to grow productive, healthy crops at home without harsh chemical treatments through soil management, crop rotation, plant selection and organic-style approaches.

The demonstration garden is a combination of raised beds and pots. A wider range of varietals will be showcased here in addition planned events.

Educational sign boards are located on site and are mounted on a signage structure designed from recycled fencing found on site.

INSULATION

WHAT IF EACH CITY BLOCK RECYCLED 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.
