The Green Water Treatment Plant opened as the Austin Filtration Plant in 1924 on the north shore of the Colorado River in Downtown Austin, which is now part of Lady Bird Lake. The plant opened after the development of a chemical treatment for river water by Dr. E. P. Schoch of the University of Texas in 1923 . It was the only water treatment plant in the Austin Water system until 1954, when the Albert R. Davis Water Treatment Plant opened on Lake Austin. From 1984 to 1986, the plant was modernized and its capacity was doubled while remaining in operation. As the Green Water Treatment Plant aged into the 2000s, then-Mayor Will Wynn proposed the relocation or closure of the plant along with the construction of Water Treatment Plant 4 in West Austin. In 2008, the plant was officially decommissioned by Austin City Council and city staff recommended developer Trammel Crow's proposal for redevelopment of  the site. Redevelopment. In 2014, the City of Austin sold the Green Water parcel to Trammel Crow for $42.2 million.

Nueces Street was extended south through the site to connect to Cesar Chavez Street, and 2nd Street was extended west to Shoal Creek. 2nd Street would later be extended west to cross the creek and connect to the street grid of the Seaholm Power Plant redevelopment. The four  blocks were developed into office and mixed-use towers by Trammel Crow between 2015 and 2022. Block 1 (The Northshore). Block 1 was the first of the Green Water sites to be redeveloped, with construction beginning in 2015. The plot was developed as The Northshore, a mixed-use building with office and retail space in its podium and an apartment tower stepping back from Lady Bird Lake, due to setback requirements. The tower opened in 2016 as Austin's tallest apartment building, which it remains to this day. Block 23 (500 West 2nd Street). 500 West 2nd Street was the  first office tower built on the Green Water site.
