>> will reconvene the special medium of the fulsome city council, the city attorney has items to report on. >> thank you Mister Mayor. City council also asked the initiative collection and litigation against thomas Mccrary, and nato, station learning center. >> with that, we will adjourn the special meeting fulsome city council and call to order the regular meeting for tuesday, June 12, the scarborough. >> council members moore, sheldon, gaillard, howell, and May close. >> rise and join us for the pledge of allegiance. >> I pledge allegiance to the flag of the united states of america and to the republic for which it stands, one nation, under God, indivisible, with liberty and justice for all. >> good evening, we have an exciting meeting, and hopefully won't put you to to sleep. It's a good meeting, I appreciate everyone's attendance, so if the clerk will start us. >> the first item is the agenda update, you have no updates this evening. The next item is business from the floor. >> business from the floor, an opportunity to speak about items not on the agenda. When I say not on the agenda, you will not get feedback from city council, because it's not an agenda item. It's illegal for us to engage in conversation, discussion, or anything that would be construed as action. go ahead and call it. >> one request to speak for Mister David hamilton. >> a three-minute time limit. >> good evening. My name is dave hamilton. I've been a construction manager for one of the bigger construction companies for a long time. I'm here on behalf of some of the residence of greg's ranch, by darrington drive. Specifically, we want to talk about what's happening. I know it's been brought up before. My primary concern is safety. There's a lot of traffic that comes through from the east to the west, and the speed of the traffic is of great concern. Personally, I was almost taken out walking a dog, with the car coming east to west. Secondary concern, is the condition of darrington drive. It's suffering premature failure right now, because the road wasn't designed for the level of traffic that's on it. Can go out there and take a look, there's a lot of areas where the sub drain is failing, the asphalt is cracked, water gets in, you have subgrade failure. It won't heal itself. You could put seal on it, but it won't heal itself. One of the more noteworthy realtors of the area, who I know, doesn't prefer to show houses over there right now, and they said that because of the traffic problem. It's better than it was, but it still has room for improvement, and the solution would be a full ingress and egress from big ranch road and natoma. I've made some drawings on how that could happen. We've gone out and canvassed the neighborhood, we have several full sheets of signatures of people that want to have something change. Specifically, have that intersection changed. Beating on doors, we only got four hard nose, we got 150 yes. It's a big concern for people. I do have a presentation, we want to meet with someone, I have a drone video of what the road looks like, looking down on it, we have pictures of the whole, we have lots of signatures, I even have a small powerpoint presentation I can show of what it looks like. It's coming apart, it won't heal itself. We are working on this, we have a lot of people in the neighborhood involved, and we will take it through the proper channels. >> thank you. You got my email? You got a hold of mark? I appreciated. -- appreciate it. Anymore business requests? Seeing none, call the next item. >> next item, scheduled presentation 6a, this is a presentation by the department of toxic substances control, regarding remedial action plans for the area 40 at the aerojet superfund site located in the folsom plant area. >> embers of the city council, thank you for having me. My name is pete Mcnichol, I'm the project manager with the department of toxic substances control. Area 40 is my side, that i manage, and what I wanted to do was talk about a remedial action plan that is currently under public review right now. Just to walk you through the cleanup on site, what we are proposing to do, and some of you May be familiar with the anticipated proposal usage, and will present those as well. I wanted an opportunity to exchange information with you. Thank you for having me tonight. Thank you, Mister Sheldon, for taking time to speak with me. My name is peter Mcnichol, I'm an engineer with the department of toxic substance control, we are on a cleanup program in the sacramento office, on the national priorities list unit. What would like to talk about tonight would be the history and overview of the site, the site conditions, specifically the groundwater and air. I would like to talk about what the objective of the preferred alternative that we would like to see implemented. We will also talk about the remediation enhancement, and potential future land uses after cleanup. And the area 40 acreage, we have talked about that, the project schedule, and questions. I wanted to indicate that if anyone have questions as you go, feel free to stop me, and we can talk about it. If not, we will have an opportunity at the end. Area 40 is south of, this is an aerojet rocket onside, this is 8500 acres, including buffer land. In particular, area 40. South of highway 50, it's prairie city road, and it is north of white rock road. That area is approximately 75 acres. The site is composed of former solvent separation ponds. These were ponds that were used to separate the solvent trichloroethylene, it's in industrial solvent from the ammonium, back in the day, the folks at aerojet would clean out the rocket casings, they would clean them out to a high degree, and use a solvent to clean those rocket casings, along with any propellant. They would contain those, and they would bring the drums here to these ponds. They were 50 by 50 foot ponds. The water, along with the tc, which allowed. The ammonium chunks would then be taken over here to this area, where they would burn the ammonium chlorate, and that is how the operations took place. The main things to think about, this is where the separation pumps are, and this is where the ammonium chlorate was burned. There are other areas out here, open space, which were thought to be areas of operation, but those have been put to bed with information showing that those weren't where operations took place. The 75 acre site, in particular, this gets into the investigation here, this is the boundary that encompasses the 75 acres. You can see the sumps appear to the north, and you can see the current features, like fencing here, roads, but the road here represents the future plan development, as well as the different colors, those are to show you the site in the context of what it is proposed to be developed out there. To the north, this blue shaded area, this represents a single- family residential housing. The green area represents the open space, this gray color represents a park. You have additional uses. This would be residential here, this would be a high density residential area. There are a number of different uses, but the main thing we are trying to do, is to make sure that this site will be suitable for open space and park uses after the remediation is complete. The other uses, like the residential to the north, and some of these other areas close to where the operations to place, those developments will take place after the cleanup is established, and we know exactly what those levels are. In order to make sure that the site remains a park and open space as we anticipate to use it for, there will be a series of covenants for the site to keep it under those uses. Some site history, previous to the 1960s, the land was used as non-irrigated pastureland. By the lady gray cattle company. In the 1960s, the area was leased to aerojet rocketdyne. As of 1962, based on the aerial photographs, that's when we saw the operations taking place at area 40, based off of ground disturbances and certain features that were there. The side, like I said, was used to separate in the northern area, and the burn area is where that was actually burned. The meeting to understand with this site, this represents an east to west orientation that goes almost to the northern part of the site. The main thing to take home, is that this is on top of bedrock. The alluvium, the surface soil on top of the bedrock, is very shallow in these areas on-site, but as you progress west, it gets deeper, and groundwater become steeper as well. Out here, in a lot of cases, even the wells are dry because there's no groundwater, a lot of areas, the bedrock is surfacing on top of the soil. There really is no opportunity for the groundwater to exist. >> peter, where there is groundwater, it's perch groundwater, isn't it? >> no, not perched. In order to be perch, you would have a groundwater horizon underneath that. Is actually first groundwater. This is right on top of the bedrock, so the groundwater out there can vary from several feet down to about 20 feet. This is just an illustration of the conceptual site model. What this is meant to show is the different receptors that are at the side, both ecological, human health, and the various land uses and the impacts that those receptors would have under those land uses right now, things being what they are. This is not represent the cleanup of the site and will be after the cleanup takes place. Nonetheless, this is a visual representation of those interactions. For instance, you can see park area, this is mostly pro chlorate there, there's a little bit of tc, but for the most part, there's that depth in most cases. There is a little bit of dioxin in the surface soil, but that's in the immediate surface soil, it's not at any depth. Will be remediated when the excavation takes place. Here, there's more open space that I had mentioned toward the north. And that's where the tc has percolated down into the groundwater. This represents the first groundwater. You can see, the depth of groundwater averages one foot to 53 feet, and averages about 18.9 feet. This figure is to show you the tc distribution out there at the site. The main thing to take part -- to take with you, is the fact that the northern areas is where that exist. The solvent. It has diluted and dissolved, and it has migrated with groundwater, and continues to the west. The groundwater flow is predominantly to the west. You can see that this also represents the new wells that we have recently installed, going back to the late 2017, 2018 results. As you can see in a lot of these cases we have eliminated the tc out here to non-detection limit levels. What it's trying to show you is that most of the tc is bound in these localized areas, and there is a little release here, but I will show you later that when we go out there to dig out the docs and virions, we will also take out this. That is remaining right there. This is the perchlorate. That's the easiest way to think about it, it's a salt, it is very soluble, it gets in the groundwater, and is taken away. The main thing to show here is that this is a result of the release that happened over the many many years that those burning activities occurred, and they are rinsing the flashing from the normal mechanisms, pushing a lot of that contaminant at depth. The perchlorate that we would be excavating out of these areas aren't necessarily a result -- a threat to human health, it's a risk to groundwater call -- quality. Groundwater quality cleanup standards. In terms of the cleanup standards now, there was a human health advisory goal -- basically, it's one part per billion, one microgram per cubic meter. For tc, is five micrograms per cubic meter. To give you an idea, for instance, we were at 10,000 over here, for the perchlorate. If you go back, you are it 80,000. What it indicates is that there is the likelihood that there is what is considered dense liquid, which means you have pure source tc that is likely right here on top of that groundwater work really, the fact is that the soil that is still there is the main source of this. Because of all those years of operation. If we get rid of the soil, we can get rid of the source, and the groundwater contamination and everything will start to shrink. The main thing out of this is that all the groundwater contamination that is leaving the area site here recommend -- rec -- represented by the rectangle will continue to be picked up by the aerojet rocketdyne groundwater extraction system. Unfortunately, the thing about that is that this represents a long groundwater cleanup standard, because the contaminants, to get from this northern portion all the way to the extraction levels, is anywhere 275 to over 100 years to get there. That's assuming no retardation, that the contaminants don't find themselves to other materials in the soil. >> is your plan to install additional wells? >> one of the things we would be doing, after the accident -- excavation is complete, is long- term monitoring. We would have wells in the groundwater, we would have wells in the non-saturated soil -- >> are there any plans to put more facilities in the area? >> that's what I was getting at, is that's one of the reasons why we like the remedy that we will propose, is because it remediates the sources, versus letting the sources remain and attenuate over the course of time. it's an accelerated remediation. The purpose of the wrap, and this is more for the public, the wrap is not development or land-use, it evaluates the cleanup alternatives that best meet the remedial action objections for the land-use. If the land is never intended to be used for residential scenarios, more of a park, maybe it doesn't need to be cleaned up to the highest level standard. At the same time, we recognize that this site has proposed land uses for residential and other uses. So in areas like this, we will be cleaning up to the unrestricted use standards, meaning residential levels. Removing all contamination, no adverse human health risk. >> but that's based on the current standards, right? >> correct. And the current standards will only get more astringent as time goes on. >> on that topic, you don't have to go back, but you show the exposure level versus breathing it in, what does that represent? >> that just shows that there are different mechanisms. For someone to be exposed, there's dermal contact, inhalation, and ingestion exposure pathways. It's showing that with the tc, it has a high vapor pressure, so it is similar to gasoline, you can smell that, and it will go to the air, so with the tc, it does present an indoor air risk, because those vapors will accumulate into an actual structure. so that's one of the things we want to make sure that we don't ever allowed to happen, is that we want to remediate those levels to the point where we don't have a risk of those migrating. That the ultimate goal. -- that's the ultimate goal. I want to just go through the components of the preferred alternative. The preferred alternative will restrict the use of groundwater at the site. There are already restrictions, and they will be of border zone established around the actual property line. In addition, we will have groundwater monitoring, that will monitor the changes in the concentrations. We expect that when we get the soil out, we expect the contaminants to shrink and dissipate as time goes on. If they don't, as we have anticipated, one of the things we are building into the remedy is enhancement, which is the ability for us to more aggressively target those contaminants in the groundwater and in unsaturated soils. What we will do, is when we go out there to excavate the contaminants, we are going to remove almost 9000 tons from the sums, but when we backfill, before we backfill those areas, we are going to put in piping networks, which will allow us to target the groundwater, it will allow us to do additional remediation. Also, for the unsaturated portion of the soil above the groundwater, we would have the ability to do soil vapor extraction, which would remove the vapors out of the soil in the event that, for some reason, the groundwater was still very contaminated after the work was done, and it had the potential to off gas into the soil. Instead of allowing to re- contaminate from the soil over the course of time, we would actively remediate it, and make sure that we would pull those off as they are releasing themselves from the groundwater. One of the things we would be doing, is we would put 3400 feet of fencing around the source area. For instance, is open space, this would be part of the plan. We would have 3400 feet of fencing that would go around, and that would really be there to prevent human receptors from an ecological standpoint, it would not prevent ecological receptors from coming in top -- contact, but one thing we can do when we backfill this area is put some riffraff and geotextile cover, which would keep those ecological receptors from rehab hitting those areas. After the fact. The one thing I would like to show you is that, as I mentioned, this is open space, when we fenced this off, these are the excavations would take place. In this burn area. You can see, this is targeted at perchlorate and dioxin, but if you look at the location of this tce, relative to the location of the perchlorate, you can see that the release likely took place right in this area, and lo and behold, that is the area that we would be excavating for the perchlorate and dioxin, and we would also to -- kill two birds with one stone. The nice thing about it is we would not allow those vapors to reside in the area where the park is going to be. We would have data to show that. The meeting to take from this illustration is that there will be a number of land-use covenants of the site to restrict future use, like for groundwater, another that would talk about requiring the area to be only a park and open space , we talked about preventing access with fencing, we will also require, depending on what the code at the time is, they would potentially be vapor mitigation requirements for these structures in the boundary. We would prevent any structures from being built over these areas until such time that we had data that shows it protected. Same thing here with the residential, which I mentioned previously. These are all things that are considered administrative controls that would allow us to remain protective of the area, and make sure that no one is exposed to anything during the time, or after. This is the land-use plan. The folsom land-use plan, so I think the main thing is to show, this is where area 40 is located. Area 40 goes from right here to hear. that is one portion. Certainly, the hillsboro development, all this development that comes into this section -- I don't know exactly where the glenn borough and hillsboro divide, but nonetheless that's a good showing of the potential future land uses. Again, this is a figure showing the area 40 in contact with those land uses. One question had come up previously from the public. How did area 40 get to be 75 acres? You talk about 75 acres, did you look at the land around there? There's more land and 75 acres. In terms of how the number was derived, it was just from adding of the open space, which is 26 acres, the park, which is 48 acres, and that represents for all intents and purposes, what area 40 encompasses. From a simplistic -- simplistic view, that's how we came up with that acreage. >> can I just summarize what I heard you say? In plain words, just to be sure that I'm clear,, and thank you for taking this on, this is a complex business, and I appreciate what you're doing for the citizens of california to clean up the site. What I heard you say was, that your intent of the preferred alternative is to clean this site up to an unrestricted status, right? >> well, we would be cleaning up a good portion, a large portion of the site to that level, but there are some things, like in the park area, there might be perchlorate at depth. Does that perchlorate present a human health risk? No, it is not. But does it present an environmental groundwater? Yes, it does. From oh standpoint, that's why those are our goals, to make sure that there is no immediate threat, and that anything, like the park, that those risks for the site are one in 1 million risks for this -- effective landing use. Anyone at the lord northern portion, you'd make sure that that is that risk, and same with the park. All those levels, that is the chosen level. The point of departure for all the different land-use. >> understood. The techniques that you will employ, in order to achieve that level of clean, is predominantly evacuation of the contaminants. So this -- those will be removed, and clean phil will be put in place. The hedge against that strategy , you are also including technology that will include groundwater remediation, and vapor extraction to the extent that there is any continuous offgassing. We continue to have get well downstream to pick up any other groundwater that's already in the process of migration that will have left the area. >> one thing I would like to point out that I didn't get to articulate, in his alternative, there are a lot of commonalities between the various alternatives I presented. One of them is no action use, you have to have that from a standpoint. One of the other things we're looking at is permeable reactive barriers. We talk about things, so one of those things we are working on as well, one of the nice things about this alternative is that we are taking out 9000 tons out of the sums, we are taking out 2000 tons from the open space, and we are taking out 20,000 tons from the park area. So this is a big undertaking. One of the things I wanted to put out, is this also has a component of his remedy, which is a 600 foot long permanent reactive barrier. What that allows us to do, is that any of this contaminated groundwater that is running off the side, as you can see here, there would be a 600 foot long permeable reactive barrier that would actually react to those contaminants, and render them in her. It would break them down. Not just the tc, but the perchlorate as well. That's the nice thing about it. We are not letting it migrate for 100 years to get there, we are taking it off right then and there. That's another thing that is really nice about this alternative. Like I said, the fact is that we have enhancements. We can go out there and put something in the groundwater, in addition to the soil removal, if we needed. And we have an ability for active soil vapor remediation as well. We have a lot of built-in provisions and contingencies to make it a really robust remedy. >> and those secondary measures, if they become necessary, happen at the administrative level. So you or your staff have that ability to look at the conditions on the ground, during the remediation process, and make adjustments as necessary to achieve the ultimate cleanup goal? The cadillac version? >> absolutely. We built this to be a modular approach, but the main thing is that we hope to be able to get at this aggressively. That's the nice thing about the remedy, is that it has these enhancements. We will certainly be able, our experts will monitor, and if we feel that it is in the best interest of the project and the cleanup, then we can implement these. They will be ready to go. There in place. It won't be a huge undertaking to implement those, and those will be designed well. >> thank you. >> are there additional questions from the council? >> we're good. >> this is pretty technical. When you go to tell the people of folsom what this is about, it will be hard for the average joe to understand. Physically, in my position, the basic thing is if you guys can't build, our kids will not play on it. So it comes to the alternate site that has been proposed, in case you can't bring it down to zero, have you checked that site to be sure that it is clear and is a good alternate side, and not another contaminated site? >> I know there was due diligence in selecting that site. I can say, based off of the people that were involved, you are talking about professional people that made those judgments, and I can certainly say that that certainly was where some operations to lace, but there are a lot of areas out there where there are no impact. There really are -- is clean land out there. But there were areas like this where we need to do something if we can move forward. >> have you done any studies or guesstimates as to how much time, once you start -- >> that the wildcard. All of us can anticipate, or have some feelings on it, but when it comes down to it, this might cleanup in 10 years, or 40 years. The groundwater might take a while to clean up. The soil is different. But the groundwater will be something that will be a challenge, and the reason is that you are sitting on top of bedrock, with fractures in it, and those bedrock and fractures is always a wildcard. You don't know how those contaminants have moved within those things. >> on the groundwater, that is only a problem if it's on the site and you have tons and tons of good clean dirt on top of it? >> the main thing is, we will have to determine at that point. That's one thing, you first want to assess what you've done, before you figure out where to go. First things first, we need to figure out the dirty dirt out check once you cut the head of the snake, the body will wither. That's what we believe. >> thank you. >> thank you. >> any other questions? Stay close,. >> yes, I'm done. I'm done with my presentation. >> first speaker tonight is janice havel, janice is followed by rob burnett. >> good evening. >> good evening. My name is janice havel. I am the chair of the community advisory group on the aerojet, now aerojet rocketdyne site cleanup. We initially started meeting early in 2001, so you can only imagine. We meet every two months, we try to keep the meetings to two hours, but you can imagine, you just heard a presentation a lot like what we might talk about at our meetings. >> and I get those emails? >> yes. You can see the meeting notes, they go into a lot of detail. I would like to talk a little bit about the levels of contaminant, contamination, pete has done a really good job of laying things out. It's always difficult talking about cleanup. For myself, there's even heightened concern given its interest in the turnaround for the city of fulsome. It just feels very serious to really be on top of exactly what is going on. The remedial action plan says that the site poses unacceptable risk to human and ecological health currently, which is true. What it doesn't mention is that the levels of tce and shallow groundwater, soil gas, and even outdoor air are among the highest observed in california. That's an important issue there. The site has up to, now, you've seen some of the levels on the screen a few minutes ago. This is up to, not over the whole area, but up to 120,000 micrograms per liter tce in shallow groundwater, which is 24,000 times the maximum contaminant level of five micrograms to -- per liter. The site has up to 268 million micrograms per cubic meter tce in soil gas, which is 8 million times the epa default screening level for protect residents from tce vapor intrusion into outdoor air. The levels of tce are so high, on portions of this site, that levels of tce in outdoor air, four feet above the ground, pose a risk for fetal heart defect. Levels of tce are likely to be even higher for infants or small children's breathing closer to the ground. And individuals laying or picnicking on the ground. Pete went over with you the removal of the soil, and that will, as he said, cut the head off the snake of the contamination moving toward the aerojet site. In that contaminated groundwater, there are these extremely high levels. >> can you wrap this up for me? Three minutes are up. >> it's important to be aware that the soil gases will continue to be there, and is uncertain how long. We would like to see the cleanup go into being more aggressive over the soil vapor issue, and I will go ahead and wrap it up there. We would also like to see numeric cleanup values. It's good that we have the one in 1 million standard now. That pete has stressed. But we would also like to see numeric cleanup values, not that aspect put off until the work plan is put in place. Thank you. >> good points. For people that don't know my background, one of my backgrounds is in hazardous materials. I actually understand anything you're saying, and what pete said. I appreciate it. Next speaker? >> rob burnett. >> good evening. I haven't been up this way often. >> you should come more often. >> my name is rob burnett, I'm active with the environment council of sacramento. Which works to protect the environment in the second region. You've just heard that portions of this site where you are planning a community park and open space are extremely contaminated. There is a major cleanup effort proposed in the wrap. The points I would like to make our that there are no guarantees that the cleanup will achieve safe levels for the public use anytime soon. Even then, there could be restrictions on certain kinds of uses. In your planned community park. I also believe that from some of the communications that there is some pressure to get this area certified as soon as possible, being free from contamination in order to facilitate the planned transfer of property to the city of folsom. I believe there's some agreement to that effect. So I think the point here is that this is an important community park, the only one in the folsom area that you are planning. But it's something that you should treat very seriously, in terms of this whole cleanup process. And we had a number of suggestions, you May be doing some already, but I would like to offer our thoughts on the importance of this, and how it might be dealt with. First, that you pay attention to the adopted policies and mitigation measures in your plans. You May be aware that the hillsboro environmental document has an additional mitigation measure, which includes a provision that, if portions of area 40, I'm trying to abbreviate this, if they aren't suitable for recreation, the owners of the land shall identify, and the city May rezone open space within that area for development as interim park and open space. That's an important one to keep in mind, as this process unfolds. Secondly, your own policies and your adopted general plans, specifically pr 1.110, basically says that land accepted for parks shall not be constrained by a variety of factors. It doesn't mention contaminated soil, but the whole point of this is, the policy says don't take that land. You signed an agreement to take this land, and we wonder whether that May end up not being something that would be consistent with your policies. The other suggestions we would offer, are that you direct your staff to closely follow the remediation process that was described today, that you work actively with us, as it goes on, that you begin making contingency plans for alternative locations and designs for the community park, you have done that to some extent, but I would keep that in the forefront of your process. Don't make assumptions. It will all come out fine. If necessary, you initiate specific plant amendments to accommodate those changes. >> a copy of your list when you're done. >> and that you consider adopting your own standards in your plan for accepting lands that have been treated for contamination, so that you have something publicly open for the record. Finally, that you proceed in an open, public manner. This is something that could be of concern to the residents of the city of folsom, and I think is open a process as you can is the way to go forward. >> don't go anywhere. Like I said, I have a lot of time working with you guys, I think overall, when we've done this, to your point, number one, there is no pressure from the city council to hurry up that site. Number two, we already present and contractually got them to set aside an alternative site if they can't do that. >> I heard that tonight, -- >> that's why I'm giving you the information. It's important for them to know that. We already did that ahead of time. I guess we are like you. We are were aware of it when we went throughout two by twos, of setting aside sites, etc. Etc., when the property came up because it was in our survey, it was owned by aerojet, we were as concerned as you and the other folks that were looking at the property. We took the necessary steps and measures to make sure we had absolute clean property for the use as intended, including the parks and open space, because as a former hazmat inspector, I don't want things offgassing. I still look, it boggles my mind that in mountain view, they have a park next to the amphitheater that you can't have , you can't have a closed barbecue there, because offgassing methane from the landfill there. That makes no sense. But the public and go out there and play and picnic. But they have the open vents there.'s we contractually obligated the owners of that property ahead of time to make sure that we had an alternate, not having to renegotiate later. They are already on the hook for that, we couldn't agree more with you. We are putting a darn thing on that property if it's not clean to where anybody can walk in and not worry about health. We appreciate all the hard work you guys have done. I spent a lot of time, as you know, you've been a great partner of ours. >> thank you. >> in the record, that would be helpful with what we are following. >> I appreciate all the information here. My only add-on would be, I didn't hear specifically, but just ensuring that there is independent testing out there. That isn't tethered to anybody we've seen or heard speak, but just we as a city that an independent report when some sort of victories declared, which we all hope is the case as far as a cleanup there, that we get some independent verification of that. Just to double down on the trust factor. >> we have been doing so all along. >> pete, thank you so much for taking time, and your information has satisfied us and been very good information. You also made it pretty easy for the public to understand. I agree with the vice mayor, at the public hearing level, I would say just as one easy factor, we understand what all those terms are, say what that is so that people understand. We know the acronyms for our industry, but most people don't. >> I don't know how large that powerpoint problem is, but I would like to get one by email. Pam has got it. >> thank you, thank you for coming out, we appreciate you coming out. We are all on the same page. I want you to walk out here knowing that we are on the same page. Thank you for that. Nothing further? Next item. >> your next item is six become a presentation regarding the folsom plant area quarterly update. >> just a moment, I'm going to find the powerpoint presentation. >> good evening, community development director. Together with steve cronn, our city engineer, we have prepared a 15 minute presentation for you this evening. The plan is to go over a brief overview of folsom specific plan history, a reminder of the folsom plan area approval, and an update on the community building that is occurring south of 15. Since 1992, the city has adopted six specific plans, all five n. Of 50 were adopted in the early 1990s, and have been refined multiple times. To adapt to the cities maturing needs and desires. This map shows those specific plan areas that are listed on the right, folsom plan area, willow springs, silver brook parkway, and brought stone. Together, these areas represent about 40% of the city's overall land area. Prior to the 1990s, we also had several master plans communities that were adopted with a different tool than a specific plan, including the tomah station, prairie oaks, and several large residential developments, such as lexington hills, and briggs ranch. One other thing to note on this slide, is the east area specific plans, which were parkway, brought stone, and empire ranch, spatially represent the equivalent land area as the folsom plan area south of 50, and went through a signature -- similar plan of facilities and financing. What I have here is a representation of a general timeline of typical specific plan implementations. With the exception of willow springs, which was a small 50 acre residential plan, all of the cities specific plans have been billed out, or are projected to build out over a 25+ year period. The first year five period as shown on this graphic, where a lot of the legwork is done behind the scenes. That includes the project detailed infrastructure planning, project financing, neighborhood design and engineering of maps, construction of backbone infrastructure, home design, and site improvements. All of that, just to get to the point of building the first home, which is shown here at just after that five-year period. I have a couple of aerial photos here, that are fun to look back at. On the left-hand side, city of folsom, 1995 aerial photos. This is after the adoption of the five specific plans north of highway 50, and as you can see, no development in the east area specific plans at all. Not even the backbone infrastructure in terms of major roadways. 10 years later, in 2005, this aerial photo, the quality is not great, but you can see that in the east area, and south areas, specific plans, you see a lot of roadways, and the backbone infrastructure is in place. You start to see the development of neighborhood parks and open space, you also see supporting services and community amenities. Then, this is that same image on the left, and we just wanted to juxtapose that against what is now the current aerial photo from google maps. This is the folsom plan today. You can see that most of the specific plans north of 50 are largely built out, with few exceptions in terms of smaller neighborhoods, some custom home lots, and some residential and nonresidential developments. You can also see that south of 50, we have the infrastructure improvements. We spent some time going through that detail with you back in January. You can see the grading and roadway improvements south of 50. Again, we shelled out a 25 year spread from the time that the specific plans were adopted. You can see that it's taken that long for these communities to plan and develop, and here are some images that represent both completed and in process development within the east area specific plan parkway brought stone and empire ranch. One of the things that I would like to talk about, I spent a few minutes talking about the specific plan phases, but in terms of the timing and triggers, they are really different in each city or county sub area based on key factors that I have listed here. I want to talk about the first two. Which a community desirability and demand. Community desirability, folsom has this space. It's obvious from quality neighborhoods, and natural setting, exceptional services, and facilities. Folsom residence want to not just day in the city, but they want their children to be able to stay in the city and raise their families in the city. Certainly, the community has a reputation, not just in the region, but throughout northern california, as being a great place to raise family. We get a lot of interest from people in the region and outside of the city. Now, as you saw in the aerial photos, we are starting to get a bigger demand issue, and that there is a more limited supply of housing opportunities north of 50. So we have evidence of the rate of new seals, you for that from constituents, and you've heard that from presentations in the last 6 to 9 months, that the new developments, the neighborhoods that are coming online, are selling like hot cakes. The home prices are increasing, both for new homes and resale homes. We have interest lists for south of 50, the property owners and builders south of 50 have started sharing that information with us, so they have a folsom ranch.Com interest list of over 300,000 people, and individual builders, over 1000 people on an interest list. The percentage of existing folsom residence on this interest list is about 40 to 50%. It's a high rate of interest from existing folsom residence, which makes the drivers for implementation of the planned area south of 50 -- the trigger is there, we are starting to see progress. In the community development department in particular, because we've been doing a lot of front end engineering, and that we are moving into a lot of building that you are starting to see. Some quick reminders about the folsom plan area approval. This was originally the land area between highway 50 south of highway 50, north of white rock road, was identified. An area for future development under the counties land-use authority. In 2004, the voters of folsom past measure w so that the city of folsom control that land for the future. We went through a few years of visioning and general land planning, and in 2011, the city council approved the specific plan and develop an agreement for that project area. Since that time, over the last 6 to 7 years, there have been refinements and subsequent plans adopted for that area. This is a list of the many projects that have come before for approval. >> sorry to interrupt. It's important for anybody watching at home, or online, to understand that the earliest discussion of the 3600 acre expansion started in 1998, and early 1999. In order to get us through this process with the county to go to lascaux, to get this. So it goes back 20 years. ? Thank you, you're absolutely right. There's a lot of legwork done and decisions made and discussions at the council and city level prior to measure w. >> just to add to that, because you are here at the time, the discussions about what the ultimate landscape was going to be in what is now empire ranch, but used to be russell ranch, that started in 1994. >> I do recall. >> and they have only started the last of division now. >> absolutely. Thank you. This is a map that shows those refinements. by refinements, this is the updated landing plan, and you can see the neighborhood planning and design that has occurred primarily in the east area, with all the neighborhoods. These are tentative map approvals, and steve will talk more about the final maps and show the development that has occurred. Now I will turn things over to steve, and he will update you on the development activity. >> is it me, or is that the worst laser pointer ever? I'm wondering if one of the ones that we have might be better. >> good evening, council members and staff, city engineer, I'm going to follow-up the presentation. >> you want another laser pointer? >> no, this one works. >> we can't see it. >> I want really point much. I'll try to describe it. >> it's not working for us. >> if you recall, back in January, I presented an update on the infrastructure status for the plan area, the backbone of the structure, and some subdivision work is ongoing now. Since that time, most of that infrastructure work is substantially complete, and ready for operation, ready to be utilized. With that, zone 45 booster pump, we will see a graphical representation of that, sewer lift station, the 45 booster pump stations, zone five water network is in place. To the far left is where the sewer station is located and constructed, it's a lift station that goes underneath highway 50 and connects to existing regional station on iron point road. That is eventually complete, the live station is operational , and the force main is in operation. When we finally have loads to start that process. >> is that at e3? >> I'm not sure we paid, it was -- to accommodate flow for the plan area. Capacity. We will be utilizing some of that. In the middle is the red circle is the 45 booster pump station. On the far right is the zone five tank and the zone 56 booster pump station, which are under construction. Both the live station and the 45 booster pump station are nearing completion. This is the aerial view, and front end view of this booster pump station. This facility pumps water up to the zone five tanks, we will see here momentarily. This is fairly complete. It's in the testing operation now, the water mains are good up to the tank. The tank itself, the zone five tank at the top of the hill, is done, but there is still site work to do in completion of the booster pump station. This is the sewer lift station, the aerial view. Is all paved, and I guess that it's ready to move, it's been tested, the power is out there, and all the infrastructure is in place. To the left is an aerial view of the force main alignment that goes underneath the freeway, through the broad stone professional center. And up to iron point road and connects to the regional station. This is the two views at the bottom are the zone five water tank, it's been coded inside and out, and is ready to accept water. All the pipes leading in and out of it have been tested and accepted at this point. On the top photo, is the front end view of the 56 booster pump station next to the lift station, that's getting the roof put on now, and is moving forward. We expect this site to be complete, as well as the booster pump station, a little later in the summer. This is some of the roadway network, at the top left is alder creek park, we saw that the previous presentation. That was constructed between alder creek -- between east bidwell and pleasantville road. On the top right is from pleasantville road heading to the south side, just to the left of the south side and live the screen is the zone five water tank. You can't see it from our side. This is the alignment of alder creek parkway that heads up the road, and makes a loop around russell ranch, which is currently under construction. We expect the concrete and paving on this section of alder creek parkway in the next month. All the underground utilities and infrastructure is in place. On the top left -- >> what was the stuff on the bottom? >> this is just to show, sorry, thank you for reminding me. >> imaginary landscaping? >> this is what this roadway will look like, some general representations of what it will look like when it is complete. Once landscaping is installed and established. The top is a representation of what's out there now, and in the future, we will have landscape corridors, trees, bushes, and irrigation along those roadway corridors. As development proceeds. >> I want to clarify, those were images that came out of the plan documents, so they are representative images, not exactly what the landscape plan is. It's just showing you the vision for what that might look like. >> I just didn't want anyone to think that it looked like that now. The miracle grow has not yet been delivered. >> to some update on the landscaping, which we will see a little bit, the landscape plan has improved, while construction is going on, we expect to see the first round of landscape improvements going in in the next month, month and a half, along that corridor. Here are a few more representations. On the top right is some of the work going on in mancini ranch phase 1, villages 89. The sound wall that is under contract for construction now, there will be landscaped as part of those plans have been approved. The installation of landscape and irrigation. Below, again, at the top is east bidwell street just heading south of alder creek parkway. That is an existing photo taken a couple of months ago while it was still green. The bottom photos are in a representation of what the landscape will look like along those corridors when we have future developments, frontage developments, and landscape corridors are installed. This is just a representation, a summary. Right now, a current update of what we have out there, we have two homebuilders that are pulling permits, and mancini villages one and two, that is taylor morrison, california. In villages eight and nine, it's lenora, which is formerly cal atlantic. We have issued for model home permits to taylor morrison for village one, division six model home permits to lennar, in village nine, and we issued just last week our first aid production home permits to taylor morrison, for village one. And we will see aerial photos of those developments. So that's what we would expect over the next several months. All four of those villages are ready for building permit issuance. You probably noticed up the hill from pleasantville road, a lot of grading and construction going on on the east side, that is the new home company russell ranch project, phase 1, the grading started about two months ago, they still had a lot of structure to do, and that will probably continue till the fall, so we would expect to see any building permits out there for construction until probably later this year, or early in 2019. That work is ongoing now. The only permits issued over the next few months will be in these two villages. For villages,. And here's an overview of where the model homes are being construct did, on the north side of mancini parkway, over the l-shaped, is the taylor morrison home. They are showing a lot, but they are only building four miles. They have eight different versions, but they are only building for models. On the south side, are the building permits for these model homes. I believe this report last week, they should be going vertical early next week. Here's an overall view, a recent photo. I believe this was taken over the weekend. Village two is the right hand corner there. That was being paved this week. The other villages are paved, and you can see on the north side, taylor morrison's parking lot, they have a sales trailer and a little parking lot for their model that is already in place. We will have a better view of that momentarily. To the right of the construction, the future villages, and on the far right on the bottom side is the future school site, that has been rough graded their on the south side of mancini parkway. It has services and infrastructure to it, so it will be ready at some point to see schools construction start there. Here are a couple of overviews, the top left corner is the parking lot I just mentioned. For the taylor morrison model. They got for models under construction. All of that work has happened in the last three weeks, so they move pretty rapidly once they get there building permits. On the bottom is another view of it. Of course, to the right are some of the models and some of the renderings of what the houses look like when they are completed, those are five of the eight different models that they have. So that's what we expect to see out there, being constructed over the next several months. There ready to pour this lab, I believe this lab, that's on the left-hand side. The sales trailer is on the top right, and again, those are the renderings of their models, which we would expect to see out there. I mentioned earlier a few other projects. Russell ranch is under construction. You can see it represented on the top right-hand corner, there. That the work you see going on. We have plans in for white rock springs ranch, which is the lower right-hand corner. We are not sure if we will move forward the summer, they have indicated that they May start grading, but if they start with grading now, it would be not ready for building permits until sometime next year. With the amount of work they have to do. The enclave is ready to get started, but they have indicated that they will probably not start construction until spring of 2019 as well. Pam mentioned earlier about the final maps. Right now we have 17 final maps submitted for review to our department. These maps are basically representative of the three projects I previously showed you, russell rent -- ranch has eight naps, white rock has four or five, and enclave, that's what is being processed together with the improvement plans for the construction of all the infrastructure to serve those maps. Each map will be presented to the city council in the future for approval. I would like to point out, on that note, the staff does not present a final map for approval. To the council. We will not even scheduled for council approval, until all the conditions of approval have been satisfied. We start that process early on, a lot of the conditions of approval are satisfied before they can start construction, and the remainder have to be satisfied before they would get a map. When you see a map on there, on consent for approval, that's why we attach the conditions of approval, and show how each condition has been satisfied, so you can see for yourself what staff has already determined, so when that map gets to you, all the conditions of approval for that map to be recorded have been satisfied. Now that we are starting to see some rooftops out there in the development, over the next few months we will see a few more going up. Eventually, probably late this year, we will have our first residents living out there. Some of those homes are going to start construction soon. With that, the next phase we will start to see some activity on the commercial front. Once you have the rooftops and residential, you start seeing more interest in the commercial side to serve those residents who will be living in those homes. Just this past week, we received our first develop an application for the shops at fulton ranch. This is him renderings of what that would look like. We are not sure what the businesses are. I don't have those numbers. >> it's a six acre site, so it's not a lot. Three or four different buildings, including a service station. >> they have some interest with that, we just received the application, so we will get more detail on that as we move forward. i just wanted to point that out, that's our first commercial development application we have had. If they were to proceed, it would be something that might get started sometime next year. With that, I would like to wrap up the presentation. Things are going to change out there over the next several months, it will become, we will have people moving into these homes. It's no longer going to be just a construction site, it's going to be somebody's home. Somebody will be living out there, so the streets have to be maintained, we will have residents living out there, and they May start having some complaints from residents for noise, construction going on before time, so this is the next phase for our department to start dealing with the residence. We should start seeing that happening as soon as the end is this year. >> were there any conditions of disclosure of ongoing construction for the first people to move out there? >> not that I know of, formally. I don't know if they were formal about that. But that is something that the homebuilders -- >> I think that would be a good suggestion for the homebuilders, to make sure that the first people that are moving in know that they will be listening to construction noise for another eight, nine months. >> and it will be our job to make sure that construction noise doesn't start before 7 am, and doesn't extend past 6 pm. >> and later on the weekend. >> correct. We will be following that. I wanted to point out that that will be coming up fairly soon for staff, with the residence. >> I want the homebuilders getting those email it's. >> and we will certainly be forwarding them to them for action. Also, these roadways will have to remain open, they are no longer construction zones. That doesn't mean parking equipment in the street, or construction materials were people can't get in and out. These are things we will start dealing with later on this year , in the community development department. >> I think it would be a good condition of approval. Before you give occupancy, you should review in your department that that satisfies what we want them to know. I'm not saying they won't do it, but I know of a site that I asked them to do it, and they didn't. >> there are a lot of conditions of approval that required disclosures, and we made sure that those disclosures are included in their application packages when they sell those homes. One of them was the overflight. >> that was my baby when I was on the commission 20 years ago. >> those are all provided disclosures. >> elliott holmes was not happy when I suggested that. >> it's an ongoing process, we have a process in place now, and we've had one for several years, that prior to occupancy, we go through a checklist of improvements. I said, once somebody moves in, the whole complexion of the development changes. Because now it somebody's home, some lives there, somebody has access, we have to provide services. Anything like that. All those pieces are no longer construction zones, they will be public streets, and need to be treated as such. That will be an ongoing thing for city staff to work with on the builders, and we will stay on them. That's all I have. Are there any further questions? >> I have one question that might sound dumb, but a lot of people are asking me. Is the water to serve that area, the connection to go over there, are they done? >> all the water connections are in place. Everyone of those subdivisions, all the hydrants are working, they've all been tested, all the water services are in place. They have water through all those four villages. I forgot one last slide, sorry. This is a rendering of the first elementary school we expected to be constructed there, that would be in the mancini ranch area. I've noted on previous slides that there was a flat spot on the southeast corner of one of the slides, where that school would be located. I believe they are negotiating trying to purchase that property, with the intent of hopefully trying to build that first school by 2020-2021. Something like that. >> any questions for steve? >> on the slide that shows the timeframe, it didn't show anything as far as infrastructure improvements traffic north of highway 50 improvements. I know last time we had this up, I asked if we could populate that on there, so we could show it happening. >> yes, the initial construction that's going on, save for those four villages, they constructed their infrastructure that is required of their development. There was nothing required, specifically, of this development north of 50 to construct an improvement. However, when we collect impact fees for the building permits that we issue, we collect fees to fund those improvements in the future. So we have enough money collected to impact, we could, based on the need, we could make improvements that are required as mitigation measures for this project. This project pays impact fees towards future interchanges, future widening and adding auxiliary lanes to highway 50, they pay a good chunk of money per permit for off-site for structure improvements to roadways and intersections and the county as well as the folsom connector. >> much like we show the running rings of all the future things, can we show the rendering of how that looks? And forecast some of that that we can explain, this is what we are theorizing? >> yeah, we could look at something like that, certainly. >> I'm also hearing roger say, and I think I know where he is going, that you give us an update of some of the improvements that will be done at iron point, but well, and so on. So what I'm hearing would be just to give us whatever the latest update timelines for those are. I know you are talking about the road that goes around hampton, where it's reconnecting, so an update on that, and

It's a good meeting, I appreciate everyone's attendance, so if the clerk will start us. >> the first item is the agenda update, you have no updates this evening. The next item is business from the floor. >> business from the floor, an opportunity to speak about items not on the agenda. When I say not on the agenda, you will not get feedback from city council, because it's not an agenda item. It's illegal for us to engage in conversation, discussion, or anything that would be construed as action. go ahead and call it. >> one request to speak for Mister David hamilton. >> a three-minute time limit. >> good evening. My name is dave hamilton. I've been a construction manager for one of the bigger construction companies for a long time. I'm here on behalf of some of the residence of greg's ranch, by darrington drive. Specifically, we want to talk about what's happening. I know it's been brought up before. My primary concern is safety. There's a lot of traffic that comes through from the east to the west, and the speed of the traffic is of great concern. Personally, I was almost taken out walking a dog, with the car coming east to west. Secondary concern, is the condition of darrington drive. It's suffering premature failure right now, because the road wasn't designed for the level of traffic that's on it. Can go out there and take a look, there's a lot of areas where the sub drain is failing, the asphalt is cracked, water gets in, you have subgrade failure. It won't heal itself. You could put seal on it, but it won't heal itself. One of the more noteworthy realtors of the area, who I know, doesn't prefer to show houses over there right now, and they said that because of the traffic problem. It's better than it was, but it still has room for improvement, and the solution would be a full ingress and egress from big ranch road and natoma. I've made some drawings on how that could happen. We've gone out and canvassed the neighborhood, we have several full sheets of signatures of people that want to have something change. Specifically, have that intersection changed. Beating on doors, we only got four hard nose, we got 150 yes. It's a big concern for people. I do have a presentation, we want to meet with someone, I have a drone video of what the road looks like, looking down on it, we have pictures of the whole, we have lots of signatures, I even have a small powerpoint presentation I can show of what it looks like. It's coming apart, it won't heal itself. We are working on this, we have a lot of people in the neighborhood involved, and we will take it through the proper channels. >> thank you. You got my email? You got a hold of mark? I appreciated. -- appreciate it. Anymore business requests? Seeing none, call the next item. >> next item, scheduled presentation 6a, this is a presentation by the department of toxic substances control, regarding remedial action plans for the area 40 at the aerojet superfund site located in the folsom plant area. >> embers of the city council, thank you for having me. My name is pete Mcnichol, I'm the project manager with the department of toxic substances control. Area 40 is my side, that i manage, and what I wanted to do was talk about a remedial action plan that is currently under public review right now. Just to walk you through the cleanup on site, what we are proposing to do, and some of you May be familiar with the anticipated proposal usage, and will present those as well. I wanted an opportunity to exchange information with you. Thank you for having me tonight. Thank you, Mister Sheldon, for taking time to speak with me. My name is peter Mcnichol, I'm an engineer with the department of toxic substance control, we are on a cleanup program in the sacramento office, on the national priorities list unit. What would like to talk about tonight would be the history and overview of the site, the site conditions, specifically the groundwater and air. I would like to talk about what the objective of the preferred alternative that we would like to see implemented. We will also talk about the remediation enhancement, and potential future land uses after cleanup. And the area 40 acreage, we have talked about that, the project schedule, and questions. I wanted to indicate that if anyone have questions as you go, feel free to stop me, and we can talk about it. If not, we will have an opportunity at the end. Area 40 is south of, this is an aerojet rocket onside, this is 8500 acres, including buffer land. In particular, area 40. South of highway 50, it's prairie city road, and it is north of white rock road. That area is approximately 75 acres. The site is composed of former solvent separation ponds. These were ponds that were used to separate the solvent trichloroethylene, it's in industrial solvent from the ammonium, back in the day, the folks at aerojet would clean out the rocket casings, they would clean them out to a high degree, and use a solvent to clean those rocket casings, along with any propellant. They would contain those, and they would bring the drums here to these ponds. They were 50 by 50 foot ponds. The water, along with the tc, which allowed. The ammonium chunks would then be taken over here to this area, where they would burn the ammonium chlorate, and that is how the operations took place. The main things to think about, this is where the separation pumps are, and this is where the ammonium chlorate was burned. There are other areas out here, open space, which were thought to be areas of operation, but those have been put to bed with information showing that those weren't where operations took place. The 75 acre site, in particular, this gets into the investigation here, this is the boundary that encompasses the 75 acres. You can see the sumps appear to the north, and you can see the current features, like fencing here, roads, but the road here represents the future plan development, as well as the different colors, those are to show you the site in the context of what it is proposed to be developed out there. To the north, this blue shaded area, this represents a single- family residential housing. The green area represents the open space, this gray color represents a park. You have additional uses. This would be residential here, this would be a high density residential area. There are a number of different uses, but the main thing we are trying to do, is to make sure that this site will be suitable for open space and park uses after the remediation is complete. The other uses, like the residential to the north, and some of these other areas close to where the operations to place, those developments will take place after the cleanup is established, and we know exactly what those levels are. In order to make sure that the site remains a park and open space as we anticipate to use it for, there will be a series of covenants for the site to keep it under those uses. Some site history, previous to the 1960s, the land was used as non-irrigated pastureland. By the lady gray cattle company. In the 1960s, the area was leased to aerojet rocketdyne. As of 1962, based on the aerial photographs, that's when we saw the operations taking place at area 40, based off of ground disturbances and certain features that were there. The side, like I said, was used to separate in the northern area, and the burn area is where that was actually burned. The meeting to understand with this site, this represents an east to west orientation that goes almost to the northern part of the site. The main thing to take home, is that this is on top of bedrock. The alluvium, the surface soil on top of the bedrock, is very shallow in these areas on-site, but as you progress west, it gets deeper, and groundwater become steeper as well. Out here, in a lot of cases, even the wells are dry because there's no groundwater, a lot of areas, the bedrock is surfacing on top of the soil. There really is no opportunity for the groundwater to exist. >> peter, where there is groundwater, it's perch groundwater, isn't it? >> no, not perched. In order to be perch, you would have a groundwater horizon underneath that. Is actually first groundwater. This is right on top of the bedrock, so the groundwater out there can vary from several feet down to about 20 feet. This is just an illustration of the conceptual site model. What this is meant to show is the different receptors that are at the side, both ecological, human health, and the various land uses and the impacts that those receptors would have under those land uses right now, things being what they are. This is not represent the cleanup of the site and will be after the cleanup takes place. Nonetheless, this is a visual representation of those interactions. For instance, you can see park area, this is mostly pro chlorate there, there's a little bit of tc, but for the most part, there's that depth in most cases. There is a little bit of dioxin in the surface soil, but that's in the immediate surface soil, it's not at any depth. Will be remediated when the excavation takes place. Here, there's more open space that I had mentioned toward the north. And that's where the tc has percolated down into the groundwater. This represents the first groundwater. You can see, the depth of groundwater averages one foot to 53 feet, and averages about 18.9 feet. This figure is to show you the tc distribution out there at the site. The main thing to take part -- to take with you, is the fact that the northern areas is where that exist. The solvent. It has diluted and dissolved, and it has migrated with groundwater, and continues to the west. The groundwater flow is predominantly to the west. You can see that this also represents the new wells that we have recently installed, going back to the late 2017, 2018 results. As you can see in a lot of these cases we have eliminated the tc out here to non-detection limit levels. What it's trying to show you is that most of the tc is bound in these localized areas, and there is a little release here, but I will show you later that when we go out there to dig out the docs and virions, we will also take out this. That is remaining right there. This is the perchlorate. That's the easiest way to think about it, it's a salt, it is very soluble, it gets in the groundwater, and is taken away. The main thing to show here is that this is a result of the release that happened over the many many years that those burning activities occurred, and they are rinsing the flashing from the normal mechanisms, pushing a lot of that contaminant at depth. The perchlorate that we would be excavating out of these areas aren't necessarily a result -- a threat to human health, it's a risk to groundwater call -- quality. Groundwater quality cleanup standards. In terms of the cleanup standards now, there was a human health advisory goal -- basically, it's one part per billion, one microgram per cubic meter. For tc, is five micrograms per cubic meter. To give you an idea, for instance, we were at 10,000 over here, for the perchlorate. If you go back, you are it 80,000. What it indicates is that there is the likelihood that there is what is considered dense liquid, which means you have pure source tc that is likely right here on top of that groundwater work really, the fact is that the soil that is still there is the main source of this. Because of all those years of operation. If we get rid of the soil, we can get rid of the source, and the groundwater contamination and everything will start to shrink. The main thing out of this is that all the groundwater contamination that is leaving the area site here recommend -- rec -- represented by the rectangle will continue to be picked up by the aerojet rocketdyne groundwater extraction system. Unfortunately, the thing about that is that this represents a long groundwater cleanup standard, because the contaminants, to get from this northern portion all the way to the extraction levels, is anywhere 275 to over 100 years to get there. That's assuming no retardation, that the contaminants don't find themselves to other materials in the soil. >> is your plan to install additional wells? >> one of the things we would be doing, after the accident -- excavation is complete, is long- term monitoring. We would have wells in the groundwater, we would have wells in the non-saturated soil -- >> are there any plans to put more facilities in the area? >> that's what I was getting at, is that's one of the reasons why we like the remedy that we will propose, is because it remediates the sources, versus letting the sources remain and attenuate over the course of time. it's an accelerated remediation. The purpose of the wrap, and this is more for the public, the wrap is not development or land-use, it evaluates the cleanup alternatives that best meet the remedial action objections for the land-use. If the land is never intended to be used for residential scenarios, more of a park, maybe it doesn't need to be cleaned up to the highest level standard. At the same time, we recognize that this site has proposed land uses for residential and other uses. So in areas like this, we will be cleaning up to the unrestricted use standards, meaning residential levels. Removing all contamination, no adverse human health risk. >> but that's based on the current standards, right? >> correct. And the current standards will only get more astringent as time goes on. >> on that topic, you don't have to go back, but you show the exposure level versus breathing it in, what does that represent? >> that just shows that there are different mechanisms. For someone to be exposed, there's dermal contact, inhalation, and ingestion exposure pathways. It's showing that with the tc, it has a high vapor pressure, so it is similar to gasoline, you can smell that, and it will go to the air, so with the tc, it does present an indoor air risk, because those vapors will accumulate into an actual structure. so that's one of the things we want to make sure that we don't ever allowed to happen, is that we want to remediate those levels to the point where we don't have a risk of those migrating. That the ultimate goal. -- that's the ultimate goal. I want to just go through the components of the preferred alternative. The preferred alternative will restrict the use of groundwater at the site. There are already restrictions, and they will be of border zone established around the actual property line. In addition, we will have groundwater monitoring, that will monitor the changes in the concentrations. We expect that when we get the soil out, we expect the contaminants to shrink and dissipate as time goes on. If they don't, as we have anticipated, one of the things we are building into the remedy is enhancement, which is the ability for us to more aggressively target those contaminants in the groundwater and in unsaturated soils. What we will do, is when we go out there to excavate the contaminants, we are going to remove almost 9000 tons from the sums, but when we backfill, before we backfill those areas, we are going to put in piping networks, which will allow us to target the groundwater, it will allow us to do additional remediation. Also, for the unsaturated portion of the soil above the groundwater, we would have the ability to do soil vapor extraction, which would remove the vapors out of the soil in the event that, for some reason, the groundwater was still very contaminated after the work was done, and it had the potential to off gas into the soil. Instead of allowing to re- contaminate from the soil over the course of time, we would actively remediate it, and make sure that we would pull those off as they are releasing themselves from the groundwater. One of the things we would be doing, is we would put 3400 feet of fencing around the source area. For instance, is open space, this would be part of the plan. We would have 3400 feet of fencing that would go around, and that would really be there to prevent human receptors from an ecological standpoint, it would not prevent ecological receptors from coming in top -- contact, but one thing we can do when we backfill this area is put some riffraff and geotextile cover, which would keep those ecological receptors from rehab hitting those areas. After the fact. The one thing I would like to show you is that, as I mentioned, this is open space, when we fenced this off, these are the excavations would take place. In this burn area. You can see, this is targeted at perchlorate and dioxin, but if you look at the location of this tce, relative to the location of the perchlorate, you can see that the release likely took place right in this area, and lo and behold, that is the area that we would be excavating for the perchlorate and dioxin, and we would also to -- kill two birds with one stone. The nice thing about it is we would not allow those vapors to reside in the area where the park is going to be. We would have data to show that. The meeting to take from this illustration is that there will be a number of land-use covenants of the site to restrict future use, like for groundwater, another that would talk about requiring the area to be only a park and open space , we talked about preventing access with fencing, we will also require, depending on what the code at the time is, they would potentially be vapor mitigation requirements for these structures in the boundary. We would prevent any structures from being built over these areas until such time that we had data that shows it protected. Same thing here with the residential, which I mentioned previously. These are all things that are considered administrative controls that would allow us to remain protective of the area, and make sure that no one is exposed to anything during the time, or after. This is the land-use plan. The folsom land-use plan, so I think the main thing is to show, this is where area 40 is located. Area 40 goes from right here to hear. that is one portion. Certainly, the hillsboro development, all this development that comes into this section -- I don't know exactly where the glenn borough and hillsboro divide, but nonetheless that's a good showing of the potential future land uses. Again, this is a figure showing the area 40 in contact with those land uses. One question had come up previously from the public. How did area 40 get to be 75 acres? You talk about 75 acres, did you look at the land around there? There's more land and 75 acres. In terms of how the number was derived, it was just from adding of the open space, which is 26 acres, the park, which is 48 acres, and that represents for all intents and purposes, what area 40 encompasses. From a simplistic -- simplistic view, that's how we came up with that acreage. >> can I just summarize what I heard you say? In plain words, just to be sure that I'm clear,, and thank you for taking this on, this is a complex business, and I appreciate what you're doing for the citizens of california to clean up the site. What I heard you say was, that your intent of the preferred alternative is to clean this site up to an unrestricted status, right? >> well, we would be cleaning up a good portion, a large portion of the site to that level, but there are some things, like in the park area, there might be perchlorate at depth. Does that perchlorate present a human health risk? No, it is not. But does it present an environmental groundwater? Yes, it does. From oh standpoint, that's why those are our goals, to make sure that there is no immediate threat, and that anything, like the park, that those risks for the site are one in 1 million risks for this -- effective landing use. Anyone at the lord northern portion, you'd make sure that that is that risk, and same with the park. All those levels, that is the chosen level. The point of departure for all the different land-use. >> understood. The techniques that you will employ, in order to achieve that level of clean, is predominantly evacuation of the contaminants. So this -- those will be removed, and clean phil will be put in place. The hedge against that strategy , you are also including technology that will include groundwater remediation, and vapor extraction to the extent that there is any continuous offgassing. We continue to have get well downstream to pick up any other groundwater that's already in the process of migration that will have left the area. >> one thing I would like to point out that I didn't get to articulate, in his alternative, there are a lot of commonalities between the various alternatives I presented. One of them is no action use, you have to have that from a standpoint. One of the other things we're looking at is permeable reactive barriers. We talk about things, so one of those things we are working on as well, one of the nice things about this alternative is that we are taking out 9000 tons out of the sums, we are taking out 2000 tons from the open space, and we are taking out 20,000 tons from the park area. So this is a big undertaking. One of the things I wanted to put out, is this also has a component of his remedy, which is a 600 foot long permanent reactive barrier. What that allows us to do, is that any of this contaminated groundwater that is running off the side, as you can see here, there would be a 600 foot long permeable reactive barrier that would actually react to those contaminants, and render them in her. It would break them down. Not just the tc, but the perchlorate as well. That's the nice thing about it. We are not letting it migrate for 100 years to get there, we are taking it off right then and there. That's another thing that is really nice about this alternative. Like I said, the fact is that we have enhancements. We can go out there and put something in the groundwater, in addition to the soil removal, if we needed. And we have an ability for active soil vapor remediation as well. We have a lot of built-in provisions and contingencies to make it a really robust remedy. >> and those secondary measures, if they become necessary, happen at the administrative level. So you or your staff have that ability to look at the conditions on the ground, during the remediation process, and make adjustments as necessary to achieve the ultimate cleanup goal? The cadillac version? >> absolutely. We built this to be a modular approach, but the main thing is that we hope to be able to get at this aggressively. That's the nice thing about the remedy, is that it has these enhancements. We will certainly be able, our experts will monitor, and if we feel that it is in the best interest of the project and the cleanup, then we can implement these. They will be ready to go. There in place. It won't be a huge undertaking to implement those, and those will be designed well. >> thank you. >> are there additional questions from the council? >> we're good. >> this is pretty technical. When you go to tell the people of folsom what this is about, it will be hard for the average joe to understand. Physically, in my position, the basic thing is if you guys can't build, our kids will not play on it. So it comes to the alterna
