I can gurantee that if The City puts both a library bond and a police building bond measure on the same ballot, neither will pass. Only one should be placed on the ballot, and I recommend the public safety building bond.
Mitchell Park Library can be upgraded as already planned, and expanded modestly by utilizing the space between the library and the community center. Ongoing funding could come from a parcel tax, and state grants could be used for capital improvements. If grants don't materialize or if they are insufficient, perhaps a fund raising drive would raise the money for the limited expansion. I personally would vote for a parcel tax to support library needs on an ongoing basis and would vote for a bond issue for the public safety building.
I am concerned that neither the Library Advisory Commission nor the Council are even discussing the possibility of modestly expanding Mitchell Park Library. Perhaps a survey asking residents which option they prefer (a brand new large building or modest expansion with upgrades) needs to be done before a bond measure is put on a ballot.
