i'd like to ask one for olson lee and ms. yunga.e of the affordable advocates raised questions about the true up amount from 17 million dropped to 13.2 and the amount in our -- the ordinance before us is 9.8 million. could you talk about how we're going to ensure that we're going to have the maximum amount for affordable housing in the city? >> thank you. thank you very much. olson lee, director of the mayor's office of housing. the memo that was cited by fernando really was the understanding early on in the process. i think that the notion of the amount of the van ness improvements were probably accurate a while ago, but things have changed on the transportation side. i think this m-o-u will be structured in such a way that the affordable housing number will be fixed, at least the 9.8. the structure that will be, as ken explained, that after the additional ancillary improvements and some staffing costs, the affordable housing will be paid out of the next set of proceeds. and then the remaining funds for the van ness improvement. an
