The Palms-Rancho Park Branch Library was Bradbury's local branch library, and over the years he had made many appearances there. He was also, of course, a longstanding advocate of public libraries in general.
My reading of the minutes of the Commissioners' meeting is that there is still a process of consultation to go through before the proposal is confirmed, but the initial stages met with overwhelming support. You can read the minutes - which include several testimonials from community figures writing in support of the proposal - in this PDF document.
(This post has been corrected; my thanks to Steven Paul Leiva for pointing out the the plan is to dedicate the library to Bradbury rather than re-name it.)
