rectangle. Here I'm going to draw a rectangle, using this as my active tool, around this area which will then identify all the census blocks that touch that rectangle, and assign them to Congressional 2 since that's our district that we've choosen up above. So I'll go ahead and do that. Once again, we see the colors change. Down below we see our deviation has gotten even better. Now the excess population in Congressional 1 is only a 1,000 over the ideal and that total deviation is down to 0.3 percent. So that's the rectangle tool. Let's continue looking at the tools. The next one over is select by polygon. Sometimes it's an irregular shape, not just a rectangle that you want to select all the blocks in there. So in this particular case, I'm going to draw a polygon. And this is where again, I choose that as my tool. I click on each of the corners, each of the vertices of my polygon. And when I'm at the last one, I'm going to double-click. As soon as I double-click, once again, I'll see the colors on the map change because those blocks are now assigned to CD2. Then we look down to the deviations, and we look and we say, oh it's still 0.3 but look what happened, we actually took out too many, now it's the opposite case. Before, Congressional 1 still had a surplus about a thousand over. Now it's a thousand below. So maybe that wasn't such a good idea and that's where these tools are good `cause you can try things. If it's not good, that is another button in here that's quite useful because I'm seeing my deviations are going like this. Okay maybe I better use, yes indeed, there is an undo button. I click the undo button and it undoes that last change. You can keep on going back until you last saved the plan and do undo and redo. I just did one undo so now we're back to where there is still about a thousand people in Congressional District 1. We're about a thousand over that ideal population. So I'm looking at the map here and I can see on the map Ko Olina and it looks like we've kind of split it in two here. And again, that's one of our guidelines is not to split communities in two. So I am going to use that rectangle tool. I see where it says Ko Olina golf club. I'm going to use the rectangle tool to grab a few more of those but not that kind of separate area up above. And indeed I see now, I'm like whoa that really made a difference. My total deviation is down to 0.08 percent. Our District 1 is only 300 above that ideal population. This is looking pretty good but it actually still looks like we've split that Ko Olina community. So I'm going to show you one more tool here and this is the line tool or polyline tool. Here, similar to the polygon, rather than doing an entire polygon, we just do a line but it can have multiple vertices. So I'll click at each one of the corners, each one of the vertices. And when I'm done, I'll double-click and as soon as I double-click, I'll see those districts change and now I have included all the census blocks that cover Ko Olina. And look at that, my deviation is even better. Now we're down to just under 200 additional in Congressional District 1 and just 200 under for a total deviation of 0.06 percent. That is pretty darn good and in fact, if I go back compare, that's even lower than their final plan. So I like this but I need to check some things, right? So before I do, I want to save this as my own plan becuase right now I'm still working with that template plan that I started with. Which I can't save changes to that, right. That's the template that everyone uses. So I need to use save as. So I've gone back to the file tab and I'm going to click save as. I'm going to make this my own plan. So with save as, I'm going to give it a 20
