The bond authorization gives the City Manager authority to bring individual requests for funding for capital projects to the City Council for their action (that is, approval or disapproval of funding). Projects often may be financed in stages - to accomplish the architectural / engineering element, to land purchase when necessary, or to perform studies as required by regulatory agencies. Approval of funding is called an appropriation. When an appropriation of funds is made, construction or whatever work the project calls for may start. Once the work begins, the city is generally committed to doing the project and eventually selling bonds.
