This bill would require the Commissioner of Cultural Affairs, in collaboration with the Commissioner of Information Technology and Telecommunications and the heads of other relevant agencies, to create and maintain an online portal to serve as a centralized point of access to city programs supporting the creation of murals and similar public artworks. Among other things, the portal would also allow private property owners to list walls or other exterior surfaces available for murals, and allow artists to submit portfolios, express interest in listed sites, and connect with participating property owners. The bill would also require the Commissioner of Cultural Affairs, in collaboration with the heads of other relevant agencies, to run a program to provide in-kind services and materials to private property owners to facilitate or incentivize the installation and maintenance of murals on their property. The commissioner would also be required to promote the online portal and incentive program, including through an interactive map.
