factors that come into the model my questions are those the only factors or other things that should be in here. >> the hydraulic model is a representation of our physical system and it has any pipe or manhole or pump station is represented in the model and we - can use it to either rap indicate or propose a new project and what happens with the new project we apply a rainfall this chart is showing you different design storms that would be applied as an input to the model we have all the pipes built into the model and see how

the water flows and can't get in that kind of analysis. >> well carrying that forward i would think that in this model there should be what kinds of of surface and yeah. yeah. >> in your models themselves. >> sorry. >> uh-huh. >> but not broke down in a certain way it is we have our existing conditions and then we can simulate a different scenario you might have more permeable - but the model has a recommendation open the ground and propose changes on the ground and see what changes that happens during a rain forest. >> okay. my feeling is that

our system would handle thing differently depending on the surface. >> so the modeling we do account for assumptions about would like for example, impermeable areas of certain sub watersheds are accounted for we simulate in the future we look at assuming that the development happens at a certain pace and the stormwater patterns are followed by the vrpdz and in parking lots and buildings they have to manage their short-term onsite that projection is accounted for that in the modeling scenarios. >> thanks. >> anything else commissioners, thank you for your presentation and take public comment on this item. >> one card here.

>> blaine bachelor. >> good afternoon good afternoon. >> i get 3 minutes; correct? >> correct. >> thank you for the opportunity to speak today you know me i live in the mission terrace and hundreds of folks that are effected by this sewer failure with the excrement in businesses like to show you a video from december 14th i'm sorry 2015. >> that's 7.4 inches of rainfall that's what it accident i applaud after all you that have been asking questions about the cost and solutions i feel

like today is the first die many residents have been heard commissioner moran you mentioned this as difficult situation that is an absolute nightmare we bought our home in san francisco we want a place to raise our family sorry i'm - very emotional and it's been a nightmare 3 months before the flood happened twice and to think we've been trying to raise a single-family in a home we don't know from the rainfall is going to bring poop into our basement has been nothing short oath crisis so i applaud you for kg intelligent questions i'm the only person that made it to the meeting i want to underscore it effects hundreds of people across district we are aware the

issues of the costs costs and no fancy graph to talk about the costs we have to deal with this every time is rains if that flooding will happen again 72 hours not flooding but sewer an infrastructure not a top graphal issue not unfixturesable but ignored at the cost of too many people we had a neighbor is close to divorce over this situation i appreciate you guys to look at solutions and again, i've gone off of script but i want to thank you for the work you've done and thank you for the studies but i want to emphasize that it is time to stop with the

grow i want to make it more able to see this isn't move forward interchanging need to be moved and the public needs construction work to keep the area - i wanted to put a new construction building control to where they have beams when this slide goes and they can go up and that the surface can disappear if there's any problems in this area. >> and i think we need you think the cost of this probably

wouldn't be as much i explained how i like this done in this construction flood area and it would probably go a little bit more in some areas and a little less others. >> thank you very much for your comments. >> any other public comment on this item? thank you and we look forward to continue this conversation and really getting more information science and data what our opposite with mostly next item, please. >> item 10 the consent calendar calendar, are considered to be routine and may be acted upon by a single roll call vote of the
