With partners including the City of Milwaukee Redevelopment Authority, Northwest Side Community Development Corporation, and Milwaukee Metropolitan Sewerage District, Reflo helped transform a blighted parcel in Milwaukee’s 30th Street Corridor into Green Tech Station—where students, researchers, and professionals learn about and experiment with forms of green infrastructure.

Ticketed, guided tours will be available at 10 am, 11 am, 12 pm and 1 pm. Click here to book beginning Sept 13.

Green Tech Station is just northwest of 31st and Capitol Drive. The site is owned by the City of Milwaukee and leased to Northwest Side Community Development Corporation, which offers programming including tours, field trips, and R&D opportunities. Reflo supported design, implementation, ongoing maintenance, education, and programming. Reflo’s environmental interns helped build the site over multiple seasons under the guidance of Justin Hegarty and Wilniesha Smith.

Northwest Side Community Development Corporation (NWSCDC) has been working with partners for the last several years to transform a 3-acre City-owned brownfield site near N. 31st Street & W. Capitol Drive into an environmental learning laboratory and green infrastructure demonstration space. They have planted more than 450 trees, installed 4 bioswales, planted more than 21,000 square feet of native prairie, constructed a wetland with more than 700 plants, and installed a 20,000 gallon cistern to capture stormwater from 31st Street. The water in the system is then used to water the plants and trees on site.

NWSCDC has also built a research plaza with 30 test cells for side-by-side experiments of green infrastructure products/technologies, which can help determine how efficient different types of green infrastructure are. Solar panels were recently installed on the roof of the pavilion space, which serves as an outdoor classroom area.

Art is also present throughout the site with a bottle cap mosaic piece adorning the fence along N. 31st Street and benches painted by ArtWorks for Milwaukee interns. Future artwork installations are also planned.

Green Tech Station is set to become a field trip destination for students of all ages to learn about stormwater management, green infrastructure, the environment, brownfield redevelopment, and clean energy. Come see the site features for yourself and learn more about green infrastructure on the tours on September 24th!


The land was once used as a railway supply staging area for nearby industry, hence the name “Station.” As industry left the area, it was abandoned.

The awkwardly shaped parcel was contaminated from this historic industrial use, requiring cleanup of the soil. Contaminated soil was mounded to the north end of the site where it was capped with clean fill and planted with native prairie and rows of poplar trees common to urban streetscapes.

The south and west end of the property contains equipment and infrastructure operated by the Milwaukee Metropolitan Sewerage District.

Deep beneath the surface, two large sewer pipes that collect water from the surrounding area combine and, when conditions merit, drain down over another 200 feet into the Deep Tunnel.

The circular concrete pad rests above a drop shaft descending into the Deep Tunnel and allows periodic access by specialized maintenance and inspection vehicles.


Green Tech Station is designed not only with science in mind but with art at its heart.

ArtWorks for Milwaukee student interns supported two facets of art engagement at the site. Processing thousands of recycled plastic bottlecaps, including those donated by Penzeys Spices, under the direction of lead artist Jenni Reinke they created a multi-panel mosaic mural: each fence-mounted panel constitutes a letter spelling out G-R-E-E-N T-E-C-H S-T-A-T-I-O-N.

The student interns also painted water-themed designs onto a cluster of Aldo Leopold benches assembled by Reflo student interns. Each student artist thought through and implemented their own design. They are all brightly painted but range in artistic styles and interpretations.

When you visit Green Tech Station, see if you can find the Great Lakes, vibrant coral reefs, a trashy beach, the aquatic food chain, water in global languages, and more.
