Neighborhoods with only a few soft sites in the quarter mile and really none of any size within a quarter mile to north beach, and using this analysis, our strategic economics recommended the dropt value increases. And they found several tools to be used to obtain the bonds for the project but none are going to pay for it in full and also found that with the limited number of sites, and changing the designing height limits will increase the revenue. And you can see that these tools could contribute from 10 million to 200 million from 5 to 20 percent of a project. That brings us to the capitol cost. inaudible who did a feasible and constructionbility repaired and each of the concepts based on a National Data base but adjusted for San Francisco and these are not inflation adjusted. But these drivers of the cost of these, are the number of stations and the amount of underground verses surface construction and in the cost ranges from 400 million from the shortest route to the longest under
As the team costs for those near the determine improvements. And we recommend this, on the allegation. These are improvements that we want to be in place for the full project as well and so the idea is just to advance to be earlier and to resume the remainder of the prop k funds. That concludes my presentation and i am happy to take questions. Colleagues, i would strongly urge, the support for this item and i think that he emphasized how busy the 38 geary line is and just to put it in the other context, there are more in that than the whole cal train system and i also have had in the notes that it is not only the that, but it is also larger than all of the ten light rails in the u. S. And so it is huge and it is a line that we dont think about having it and lighting along the geary corridor and it has traveled through the districts as well and i think that it is a a lot of anticand along a lot of the corridor as it is being planned and investment that is being made today, imented to sa
The extension to make use of the tunnels that are completed and possibly preserving the rightofway along the corridor and the transportation of the board at the urging of the commissioner chiu and we are pleased to share you the results of it today, and i will turn it over to the alignment. Thank you. And welcome, and my name is gardi and that is what we will see today and we can move on it quickly and the concept alignments, and what the columbus avenue and up the street and over on the beach street and the one way loop and so that we forced it in the three but there are three different alignments, and the next slide . Okay. And out of those four corridors we looked to the scope of work at all subway and subway surface alignments and powell street had some more actual alignments there because we look at different ways to turn the vehicles around and the runway loop turns them around and services them and because we need to do the extra space and so we divide up the 14 and we found in
Interagency team and acknowledge the excellent work by the transportation as well. And perry, and joshua swifty and our consultants. So as you know as the central subway comes near completing last spring, it grew to work on the extension to make use of the tunnels that are completed and possibly preserving the rightofway along the corridor and the transportation of the board at the urging of the commissioner chiu and we are pleased to share you the results of it today, and i will turn it over to the alignment.
