As alderman, Solis focused on job creation and physical improvements in the 25th Ward (Lower West Side) such as expanded National Museum of Mexican Art in Pilsen, the Ping Tom Memorial Park in Chinatown, and a rehabilitation of the Archer Court Senior housing development. Solis also encouraged and negotiated with the International Produce Market and American Linen Company to stay and/or locate in the 25th Ward's Planned Manufacturing District (PMD) which has brought and continues to bring jobs and capital to the community.
