alternately, i suggest you consider the russian hill, a sea cliff, and the presidio for possibilities but the easiest ones are some of the changes you made monday. thank you. chairman mcdonnell: thank you. >> good evening. i have sat on the board for four years and have been a resident for 10. i want to encourage you to stick with that decision. there are many reasons, most of the neighbors are in overwhelming favor of keeping the area in the-5. i will resonate the same tackling --comments. please note in doing all this the neighborhoods of district 1 and 2 did not participate because there were not interested in it. we have spent countless hours working with one supervisor and working with multiple supervisors, twice as much work and many meetings. we are strongly aligned with d5 and splitting us would make us a minority in voicing our opinions. our neighborhood is fragile. andou our advocacy is needed to improve the area. this is a natural boundary that does not divide the community. if you want to go back to the street, our

sea cliff beach among them. tony and his grandson are here from tracey, where it's hot in the 90s. >> it's a beautiful day. >> we're at the beach with my grandson and we're just enjoying the weekend. >> reporter: for visitors, this was good timing. they pacificked a california site at sea cliff a week ago without knowing it would reach into the 80s at their home in vacaville. it worked out pretty well. >> we were scheduled early in the week and happened to be able to stay the weekend. >> reporter: so it's good timing for you? >> very is good. >> reporter: the numbers posted here lifeguard station says 80 degrees and you can see waves of heat coming up offer the ground. looking at the water it tells you it's warm when you see people besides surfers getting in and hitting the waves. i look the down the beach and all you need is proof that the area is getting summer-like crowds to go with the summer- like weather. >>> and if you are looking for something fun and free, why not head out to one of america's national p

in particular i would like to commend you for ensuring that sea cliff is kept whole and the part of the district 2. furthermore i would like to reiterate as a district aide to president, i live in mission delores in chattanooga street. i am concerned if it moves into district 9, not only will that lead to an exceptional -- unacceptably high population, it would leave district 8 somewhat, especially my area in the castro which is comprised of moot -- mostly renters. the inclusion of the corridor is extremely important. furthermore, i would like to echo the concerns of the speaker before me. if we are moving all the portal into district 10 it would offset the hard work that task force has accomplished. this would be a disservice to the community groups that have come forward. at multiple meetings and expressed their concern that is so well reflected in this current map. thank you. vice-chair lam: thank you. next speaker. >> these individuals here wanted to ask if they could use their time jointly to present a video that is queued up. vice-chair lam: i did get that earlier request. we are

this is the planning neighborhoods of sea cliff. would you like to also see, it also goes and extend out. any other questions? all right. miss tidwell? >> yes. >> mr. schreiber? >> yes. >> mr. pilpel? >> yes. >> miss mondejar? >> yes. >> miss lam? >> yes. >> miss ma melara? >> yes. >> mr. league? >> yes. -- mr. leeg -- leigh. >> yes. >> no. >> i will look at the deviations. >> thank you. >> can i make a comment while at the look at the numbers? >> sure. i think the pop lore initially had either ben the four blocks between two and five as a way to clean the lines. so since those are not submitted as part of a neighborhood, i would suggest we look there to the extent we still have a population issue. >> ok. >> mr. chair, we have the deviation. it is negative 4.997%. >> are you comfortable? >> i'm comfortable. >> thank you. thanks for that exercise. let's visit now the less again attempting to move fairly swiftly through each of these considerations. let's go to the question of d-60 border, at the same time we will secondarly visit the

the other would be the 49 people in sea cliff we could consider looking at. commissioner tidwell: the other question i had and this was the district issue was the line between six and 10 on 16th street. i thought that was due to the map, right? >> that was due to the map, we cannot move anything. >> there is the line between six and 10 and the corner of 16th street. >> ok. >> can i ask a clarification question? chairman mcdonnell: it may ask a question with regard to a break. -- you may ask a question with regard to a break. i will hold you hostage to your own question traded depends on, this just in, paetec at 8 -- pizza at eight. we will break as close to 8:00 p.m. as possible. there is a natural moment there. thank you, madam clerk. we have a full list and complement. i should ask in that federation of proposals. in the categories of non- population areas to visit, the only one i have listed is golden gate park. are there others? commissioner pilpel: i was hoping at some point, time permitting today or saturday that we would walk through the lines quickly

these are portions of the cliff rotates out to sea. >> when we look at this cliff, can you tell us what of the features that we can see? >> we are lucky to have a very fresh exposure. there is a large overhanging block. at the very edge, you can see the roots coming out. they are part of the problem. in addition, these are sandstone and shale. they have been uplifted and faulted and put into the position they are in today. on the cliff face, you can see the bedding of the shale. there are vertical cracks that filled the water and plans is growing. -- and plants are growing. the cumulative effect of the fresh cut with the debris sitting on the ledge, luckily we have a chance there to protect us from rocks going on the street. >> this is one type of rock salt and we will look at a few others. what will we see? >> i think it would be appropriate. we have been talking about rock salt. there is instability that occurs at telegraph hill. this was more in the earth flow and debris flow kind of movement. this moves downhill as a result of the rations from the earthquake. that is where we are he

this sea of mesquite and cactus that you see below here was once the reservoir impounded by the dam that stretched nearly half a kilometer from that cliff face on that side all the way over to this cliff face over here. at its peak, the reservoir surface area equaled 40 football fields. keach: spencer has determined the reservoir's size by measuring the silt that had built up behind the dam. we're behind the dam now, walking through a channel cut right into the silts that were deposited behind the structure. these silts that you see on both sides were brought in here by the water that flowed into the reservoir. when the water hit the dam and stopped, the silts were dropped and deposited in a series of layers. keach: the silts show just how deep the dam once was. the top of this mountain of sediment would have been the floor of the reservoir. spencer: it dawned on me after a few days that what i was dealing with here was an engineering feat, the magnitude of which was hard to grasp at the beginning. the planning, the foresight, the organization that was required to carry out this incredibly massive task was something that i could only ap
