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
Construction through the information a method that is less disruptive to the method and costs more another method slightly less but more disruptive the yellow t open the side that has another spur those are areas under the most disruptive Design Method youll have to open up the street called cut and cover construction to put a station and tunnel and continual north the less disruptive will produce that by half the more disruptive is 400,000 and the less is still not cheap at 350 million that is i have issues this station is build by itself youll need the turn around facility and at the end of columbus avenue youll have a turn around facility the cost estimates is a turn around and plus you have to fully utility i utilize the tunnel they have no track to mta still holds an active lease on the property to remove. The t and the owner is prepared to go forward with construction on 19 unit at some point after the lease is over or it is removed early at this point our director ed reiskin sai
Involved with that, one of the first decisions we want to keep the study looking at existing transit loimentsz figuring we didnt time to go into other areas so the alignments you look at are columbus with the stopping bus and United States powell street and beach street with the Transit Service on that out of those alignments we came up with 14 actual alignments implicit we will look at in a second so in addition to the twoway ones on columbus are back down up to the minute powell it goes over beseech and one way loop alignment it connects the loop together all alignments assume the existing tunnels between chinatown and north beach will be used for some sort of service okay. Next slide so the 14 alignments are many the 4 colors columbus and the loop is in light green all of them have a two or three stations not a requirement but thats how this plan was laid out and they looked at subway and surface this large number of alignments some under the subway and the subway in the first part
40 minutes the green line which will be phase two t third and potential phase 3 the running times are 14 to 17 minutes a little bit longer than for the loop twice as fast next one im going to turn it over to bob at this point. Thank you. Well turn on the milking for you. Okay. The Transportation Authority lead the writing with the large improvements on the travel times it attracts a lot of rear view mirrors over 40 thousand additional trips on the t line thats is a 50 percent increase new riders to the muni system so folks taking cars or not making the trips the remaining trips are from the tooift to the slower transit that existing e exists today it is a balance out of the overcrowded like the cable car and the bus one concern we had are ridership this slide shows the peak hourly load that explicit increase with the daily ridership thats due to the all day ridership that is attracted to the extension you see that the 3 minute head ways the upper red line on the graph is sufficient to
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
