julia dawson or others may be able to correct me but a change of less than 15% is straightforward inmost cases, and the controls can be set at different levels so when you design your original appropriation for the bond, you can hopefully obviate most of the reprocessing by the board of supervisors by purposely sizing the project and program allocations. just to say that, so you are aware and there are significant changes. i think the board approval of the supplemental is an important part of the overall transparency on the bond. that is the thinking behind it but we can certainly look at the original bond allocations to try and make it easiest to manage. >> i understand the need for oversight because that's why there is a go door to go back to begin with. there was some misuse of bond funds for previous bonds, where things were supposed to have been used for but they flat out did get used for. but i think that there has to be some middle ground between the way we are now and the way we were then. i would never want staff to change the appropriation without at least informing the boa
