Jefferson Arms Redevelopment Seems to be Back on Track


The redevelopment of the Jefferson Arms building in downtown is back on track after the city's Clean Energy Development Board approved PACE financing for the project.


This step secured financing for the over $145 Million project. Plans call for the building to be redeveloped into 225 apartments, 235 hotel rooms and 29,000sf of retail space. The Jefferson Arms project has been planned by Texas-based Alterra International since at least 2016. Controversies surrounding partners, project components and funding have all come and gone and numerous start dates came and went. And while financing has been secured, there's still no word yet on when the project will start.


Previously, plans called for an AC Hotel by Marriott to be the hotel brand, but it's unclear if that's still the case. Alterra previously engaged Merriman Anderson Associates of Dallas Texas to serve as the architect and DTLS Studio of St. Louis to serve as landscape architect.


The return of the Jefferson Arms project is just one of several big projects that were either announced or advanced in downtown this year. 2022 has seen the following projects be unveiled or advanced in downtown.
