 Hello. Welcome to the second flood warning public meeting. This is a progress since our first public meeting, which was held on the 23rd of March this year. And I want to welcome you all to this exciting project that we're doing in stormwater management to enhance our flood warning capabilities citywide. So my name is Ranjan Esmutaya. I'm a senior professional engineer with the Stormwater Division Transportation Public Works. And you all can see my email down there. It's my first name, dot last name at FortworthTexas.gov. And if you have any questions related to this project, please feel free to email me. So I'd like to acknowledge the funders for this project. This is a matched project. The match is being cost shared by the city and the Texas Water Development Board. And the Water Development Board is using the flood protection grant that the governor created in 2016 to fund these types of projects. So we appreciate the support provided by the Texas Water Development Board. And we also acknowledge the 60th anniversary of the formation of the Water Development Board. They've been doing great work since their formation to help with the water resources, the water supply problems that the state encounters. So I'd like to acknowledge the contributions made by several agencies to make this project a reality. There are departments within the city, the Office of Emergency Management, the Stormwater Transportation Department. There are several people that have contributed towards where we are right now. And externally, the National Weather Service has provided feedback and other agencies such as the USGS. The neighboring cities have also contributed towards hosting weather stations that we will talk about here in a little while. So I want to acknowledge some of the neighboring cities that have contributed towards the IRFs. I also want to thank you. Thank you for staying engaged and involved and providing feedback. So the purpose of the grant is to develop a citywide flood warning system that is reliable and relevant. We'll be using the existing network that we have. It's called the High Water Warning System. We'll make enhancements to that. And the focus on flood warning is to collect the data that's being collected at weather stations, at high water warning sites that monitor the water levels and provide that to the public and emergency responders. And the third and final purpose of the grant is to develop a flood response plan that identifies the major threats and the response to the flood threats that the city potentially faces. The grant is, as I mentioned earlier, a cost share and the city is providing the match in terms of procurement of the software, consulting services and through in-kind travel match as well as in-kind staff time. The water development board portion of this grant is being used to procure equipment for this grant project. So I'll go through the schedule in just a little while, but we have also requested a nine-month extension for this grant. It was ambitiously aimed at about a one-year project. We believe that we need another nine-month to comfortably complete this project. So here's what I had shown earlier. The first public meeting, you all had attended the March meeting. We were scheduled to have a meeting in June-July if everything was crunched down to one year. But as of now, we believe that we need a nine-month extension. So here we are in October-November. We had a second public meeting. And we have made good progress on the software. We got about halfway through on the equipment installation process. And we are about 60 to 70% of the way there on the flood response plan. So what's the new schedule going to look like? We anticipate finishing the installation of gauges around May-June timeframe of 2018. We'll begin the installation of that equipment, which will consist of weather gauges and the telemetry around January-February. The software itself has gone through a procurement process. We are in the process of writing a contract or inking the contract. We have negotiated the contract. We just need to get approval from the council for the software contract. And then that implementation will run through May-June timeframe. The flood response plan, as I mentioned, also has made relatively good progress. We got to refine the flood response plan developed to date. And then we'll run it through a tabletop exercise, receive public comment, receive external agency comments. And then we'll revise that flood response plan subject to the lessons learned. And then it'll be submitted to the war development board. The grantor, the war development board, requires a final report on this project. And we will generate that during the end of the project period. We anticipate holding our second public meeting once all these three main components of the project are complete. So here's our existing system that we plan on enhancing to create this flood warning system. The high water warning system is based off of alerting roadside drivers to high water on the streets at 52 hazardous slow water crossing sites. And the data that's generated through the alarms when the roads get overtopped is submitted to the first responders. So these are real time alarms that take place in real time as the water starts overtopping the streets. But you see on the map are the different faces that the high water warning system went through over the years. It began around 2006 and then got enhanced subsequent to that to the 52 current sites that are being monitored. The data itself is collected in these field sites and then transmitted to a receive station at Bernard Plaza. So here's a little bit more detail of that. The water levels are measured by pressure transducers. And then the data that's collected again in real time is transmitted from the field sites to the receive station at Bernard Plaza. My mouse is circling the internals of what the receive station looks like. So data comes into an antenna at the top of Bernard Plaza and then in the building there is a receive station that consists of receiver decoders that convert the data after it's gone through some radio frequency filtering through these cavity filters that get then decoded to data that's sent to a server, a flood warning software that's hosted on the server, processes the data which then gets cleaned up and is used to generate alarms as well as used to generate display of the data. I do want to talk about the rain gauge system. At these low water crossings there are rain gauges. There are about 39 rain gauges spread out throughout the city as part of this network. Eight of those rain gauges are on dedicated weather stations that measure not only rainfall but other things like air temperature, barometric pressure, humidity. So the protocol that's used to communicate from the field is called alert. This is a 1970s based technology that transmits whenever there is a trigger like if the tipping bucket tips over in those rain gauges that creates a trigger that's sent out from the field to the receive station at Bernard Plaza. So all sites that collect data report whenever there is a trigger event. Either the pressure transducers are measuring water levels and that water levels get transmitted in real time or the tipping buckets measure in real time. As well as other data that's collected on the sensors or the batteries that power the system, the solar panels. So there's a lot of data that's collected and sent from the field sites. Of course not on real time like the rainfall and the water levels but they are transmitted. There are close to, totally across the system, there are close to 7 to 800 different types of sensor data that's generated which includes the batteries, the solar panels and things like that in addition to the sensors that measure the water level and the weather. This alert protocol has no error correction so whatever data is collected is transmitted. There is no receiver to transmit a correction protocol employee to check whether the data is valid or not that's transmitted. And then during high rainfall events as you can imagine these tipping buckets and water level sensors get very busy and there's a high level of traffic, radio traffic generated when there is a rainfall event. And if you were to try to expand this network your data loss gets even worse. The good thing is this technology is outdated and there's more recent communication protocol. However there is a little bit of a compromise in terms of what you gain in terms of the security of the data transmission. And that is that the alert transmits very quickly whenever there's an event it transmits to the relay station or the receive station in Burnett Plaza and that transmission time might be in the millisecond range. However you do have this problem of the data collision. The server that's receiving the data can only deal with one transmission at a time even though it's within the millisecond range but if you have lots of transmission that just collide with each other that becomes a big problem. So that's one of the limitations of this alert system is the data collision is the biggest issue. So what does a flood warning system look like compared to this high water warning system? We will continue to use the high water warning system with its field sensors which is mainly big gear towards alerting the roadside drivers of floods at these low water crossing sites. So that will continue to run. But we'll be enhancing that system with additional rain gauges. We'll be improving the telemetry. We'll be improving the software. So the experience that the public gets from this improvements will be significantly more than what's currently available. And the data processing and things like that also will get enhanced through use of the alert 2 communication protocol. So here's the alert 2 communication protocol. It's an upgrade to the older alert protocol. It is designed for higher transmission rates and it uses GPS clock technology to keep up with the transmission and the receive time. So you don't get data loss because you got a time slot associated with the transmission. There is error correction in the protocol. So there is the transmission structure, the bit data that gets transmitted has error correction codes built into it so that the receiver can validate the data as it's being received. And the receive, actually the transmit message can be variable length instead of a fixed length as it is in alert. Now there is as I mentioned a compromise and that is that the alert 2 because it does a lot of error correction and uses the error correction methods. It does have a latency period of about one to one minute or so from the time that the data is collected. And then the alert 2 protocol is what they use in the system. They are in Harris County and during Hurricane Harvey it performed really well. Not much data loss. If there was any data loss it was very minimal. So as we transition from the current alert to the alert 2 protocol we'll be doing it in phases instead of pulling the switch immediately. The new weather stations that are being installed as part of the war development board grant effort will be placed on alert 2. And there will be alert 2 equipment at the receive site at Burner Plaza as well as we'll have a second receive site at the Bridge Street tower. So we'll have two receive sites just in case Burner Plaza goes down for whatever reason. And the new alert 2 will be put on a third frequency. We currently have four frequencies that we use. Two of those are actively used for alert. One of those two remaining two will be used for the alert 2. And then over the years over the coming years as we get more experience with alert 2 the alert protocol will get decommissioned. And then all the transmission sites the current high water warning system transmission sites will be put on alert 2. There will be some additional modifications made. Currently all the sensor sites transmit have radios and they transmit to Burner Plaza. So that creates a lot of communication overload during an event. We want to try to minimize that. And we're going to do that by having the master controllers that are located at these remote sites. Be the only ones communicating to Burner Plaza and then the localized communication between the field sensors will be handled by the master controller units. So I want to step back a little bit at this point and provide and I apologize as I move the mouse back and forth. I'm trying to make sure that you all can see this clearly. Okay, let me see if I can maximize this so I don't have to do that. Yeah, I don't have to do it. So the idea with this with the citywide is that we are going to be locating a various number of rain gauges. We think about 20 different new sites. We have about 39. Let's go around that up to 40. So it's the video talking about whole numbers. So total we'll have about 60 rain gauges spread out throughout the city. Some of them actually will be located outside the city limits. We are collaborating with neighboring cities to for them to host some of these rain gauge sites. So we have a good distribution of rain gauges. But that by itself is not going to provide a lot of information citywide. The city of is about three. The city of Fort Worth is 350 square miles. And obviously that's a large area. So the current density is about one gauge to about 10 square miles, which is not too bad really. But when you're dealing with real time, you do want to try to capture as much of that spatial variability as possible. So we are planning on tying in as it's right now. So this is not nothing new as it's right now. We're planning on using a hybrid approach by tying into the next rad radar measurements that are made by the National Weather Service. So the Weather Service does do this already. It's just that we'll have more rain gauges on the ground to help enhance that process. And try to minimize the problems associated with predicting rainfall from the next rad radar system. So the current next rad radar system has been updated to transmit in what's called dual polarization. So I'm highlighting a little antenna in the lower right corner here to show you the transmission, the cartoon transmission of a radar wave in the expand. And the National Weather Service has enhanced those radars to transmit in two different polarization states or different directions. One in the horizontal direction and then another wave in the vertical direction. So these two different types of polarization let you better characterize the type of rainfall or the types of cloud characteristics. The cloud as you can imagine consists of all three different phases of water. It's in liquid form, it's in solid form in crystals, ice crystals, as well as it's in the vapor form mainly below the clouds. And so we get to experience the liquid form as it falls down as it precipitates out of these clouds. And so these radar systems have to be sophisticated not to go too high. So you don't hit those crystal layers as well as not go too low. So that's where the tricky part is. Anyway, over the years the National Weather Service has gotten good about characterizing the rainfall using the radar system and the more recent radar systems since 2013-2014 timeframe have these dual polarization capabilities, which has provided enhancement in terms of characterizing the rainfall and other severe events. So the main point I want to make here is that while we will enhance the network of weather stations and rain gauging in Fort Worth, we will tie in to the radar system to provide a more comprehensive view citywide. Now that doesn't mean that we won't be using the radar only system as and when needed. So here's that next rat system I was talking to you about. This is one of the systems you see on TV weather stations. The picture on the upper right corner shows the radar station at the Sphinx airport. And on the bottom I've shown you the signatures that were being picked up during Hurricane Harvey. So it's actively used not only by the weather station but by a variety of other folk that provide the weather service information. Another system that is located in the Dallas-Fort Worth area is this Casa radar system. And whereas the next rat national weather service radar system sweeps across a much larger swath of the sky, the Casa radar system focuses on the lower elevations. So it doesn't have to scan as much and the return period on these Casa radar systems a lot faster in the minute range whereas the next rat system takes about five minutes, could take about five minutes. I have shown you the circles that are these different radars that are located in the Casa radar. One of these circles is a transmission radius from one of these radar sites. And there are eight of these radar systems and the more the overlap. So areas where you see a lot of overlap you're going to have a lot more confidence in the measurements than areas that have no overlap. As you can see out in the south as well as the southwest as well as in the northerly direction. And on the right side I have showed you an event from January which had severe tarnatic events and you can see all the red that's the high intensity rainfall events. Actually the white spots that you see there are areas where the tornado that had wrapped around it a lot of rainfall touch ground. So this radar system provides quite a bit of not only rainfall information but also wind information that enhances the forecast capabilities that can be used to warn people about extreme events. So we are fortunate that we live in an area that's covered by these two different radar systems. We'll work with the National Weather Service on the next rat and then we'll work with the Casa team. And I'd like to acknowledge at this point I forgot to acknowledge the Casa team when I gave you my thank yous but the Casa team which is based out of research teams at the University of Massachusetts, University of Colorado and UT Arlington. So for our part we are looking at trying to generate thresholds that could be used to program the radar systems to provide warning. And one way we are doing that is to look at the high water warning sites these 52 high water warning sites which have been engaged for water levels which have been engaged for rainfall and look at trends in the water levels and look at trends in the rainfall to see whether there are patterns that we can pick out that could be programmed into the radar measurements that are being monitored in real time. So what I've shown here is a graph of that and let me spend just a little bit of time going through this. So the dotted lines in blue or the dotted icons in blue is the water level measured at a low water crossing site. In this case it happens to be at the 28th Street and Labo Creek which is a flashy creek in the city. And this was an event from late November in 2015 and you can see there were two overtopping events. Anything over zero means it overtopped and on the time frame between 26th and 27th there was an overtopping and then immediately after the 27th midnight there was another overtopping. And that tends to be a lot more dangerous because it's in the dark and people can't see. So there were two of these events and then the red dots show the accumulated rainfall. So what we mean by accumulated means that this is a running tab. It's a total sum of the rainfall as it's being measured. It's not the individual measurements with time but the individual measurements that are summed up over time and that's why you see an increase of the rainfall. And what you want to notice is that the steepness of that cumulative rainfall tends to steepen up as we experience these flood events on the ground. So that's one way that we are using these measurements to inform the radar system. And currently we are working with the CASA team to look at 15 minute increments of rainfall and as the intensity within those 15 minute increments start peaking up we've identified to watersheds below those CASA radar footprints to issue alarms. And that's still in development but as we learn more and test it out we'll be in a state to make that more publicly available. I just wanted to give you an example of the way we are using the ground measurements to help inform the forecast. So this question came up at the first public meeting and that is that we are going to be using the rainfall measurements from both the ground measurements as well as from radar in either from the radar form or in a hybrid form to make the lead flood warning. We are not at this stage going to take that rainfall ingested into complex numerical hydrologic models and run those hydrologic models to make forecast. We're going to rely on making those warnings off of the rainfall at this time. Okay so I hope you have a good understanding of what we are trying to do and from here on out I'm going to be talking about what we have done to date on this project. So we've created a website for you all to access and the website is www.fortworthtexas.gov forward slash flood warning. We'll be placing updates this public meeting as well as the previous public meeting is recorded and posted on there. We have a executed contract with a consultant firm called DDI to help us with our project. We have resolved some of the data conflict problems that we were experiencing with our current high water warning system at the received site by squelching the noise at the transceiver site and then we have done some preliminary engineering structural engineering analysis of the second received site at the bridge street tower. So the second received site is going to be a failover system in case the primary received site at Burnett Plaza fails. And we've identified issues that need to be resolved to make the high water warning system a little bit more reliable in terms of the water level measurements as well as the weather gauging. And we have developed a strategy to locate the weather stations in and around Fort Worth. We have selected a software and we have a draft of the flood response plan in place that's being refined. So here's a picture of that bridge street tower. This is the second received site. It's about 250 feet tall and receive antenna will be located at the top and a cable coax cable will run from that bridge street tower to a building close by that will have the transceiver and the Digiport boxes that will take the data and transmit it to the server. It's pretty much like I showed you earlier for Burnett Plaza. So our strategy for locating the weather stations is to fill in the regional gaps. If you look at the region and I think the next map shows that region. So let me bring that up. No, it's not. So it's further down on the slide deck and you'll see what I mean by this. But the region in the south, southwest and the westerly regions have missing gaps in them. And those gaps will fill. So we have more weather data farther out and lots of the frontal systems come that way. So it's totally justified to locate weather stations out that way, that side. The telemetry itself, we can reach out to 30 miles. And then within flood prone watersheds, we'll locate the gauges in the upper one third of the watershed. The site selection themselves have to go through a vetting process. We need permissions from the landowner. The site has to be secure. There needs to be some fencing around, not necessarily around the weather station itself, but close by. So it serves as a deterrence. And the site needs good access so we can go and regularly maintain it. There needs to be a clearance, a 45 degree clearance above the weather station. So there's no obstruction that will prevent the rainfall measurements and other weather parametric measurements. And we plan on locating the rain gauge at all about 10 feet, not more than that. Here's the radiopath analysis that told us how far out we can go. So anything that's colored in blue all the way to red. So red means great reception. Blue is lower reception potential, but we can still receive it, receive the data. And we can go out actually all the way to Grandbury if needed. The actual expansion plan is going to go out through to about Creson, Godly, God and Joshua. So these are the cities we're talking to right now, Joshua, Godly, Creson and Wetherford, and then also Mansfield out here to locate the gauges out in this direction. So this is the Bernard Plaza strength of reception. And here's the strength of reception from Bridge Street, not as strong, but that's not a big concern because we don't expect this Bridge Street to be down or be actively used for extended period of time. It's just serving as a backup just in case the transmission to Bernard Plaza fails. So we feel comfortable with the Bridge Street tower reception. And let me add that in this picture what you see as those inverted triangles are the existing rain gauge and weather station sites. So we're going to significantly expand the footprint out west, southwest from where we are right now. Here's what the proposed weather station is going to look like. The components will be a multi-sensor that measures all these different types of parameters including rainfall. We'll have a supplementary tipping bucket rain gauge at some of these sites to validate the distrometer that's located in the multi-sensor unit. The transmission box will consist of the alert to controller units. And the concrete pad and pole is not going to exceed more than 10 feet. Here's the distribution of rain gauges and weather stations in the Metroplex as they relate to where we are. In the green lines are the major watersheds that drain the city of Fort Worth. And as you can see areas in the south-southwest there isn't a lot of areas that are gauged. And so that needs to be filled in so we can capture the rainfall patterns that are coming out from that direction. We have access to nearly all the other weather stations that are shown on there from our partners out east and from other directions. I wanted to go through, let me see if I can get that picture down so you can see it. I want to go through the strategy for locating gauges in watersheds. We are not going to have a lot of lead time because the floods when they hit a watershed can impact the outlet of the watershed within about 20 minutes. We don't have a lot of time. And locating the rain gauge on the low end of the watershed as it is right now with the high water warning system provides very limited lead time. So we want to try to go out to the edges of the watershed as much as possible. And that's what we plan on doing. So the plan is to locate these weather stations close to the edges of the watershed divides so that if and when these rain gauges by themselves get used to provide that lead forecast to some of these more flood prone watersheds, that will be on average about a 20 minute lead time. I do need to mention that the National Weather Service, the next rat based predictions can go out to about an hour. The numerical models that they use and provide the quantitative what's called the QPEs can go out to like 18 hours. But that's using numerical models and those radar signatures can get used in more sophisticated models to provide of course less lead time. The CASA radar also runs atmospheric models based off of the radar footprints and those can go out to about 15 minutes. The CASA radar footprints like 100 meters. So it's very much more precise than the next rat. Next rat footprints about a one mile by one mile area. So the idea here with this, with locating these gauges as well as with the radar system is try to provide as much lead time as possible. And the more we can ground correct those radar signatures and more we can locate these gauges at strategically located positions the more lead time we'd have. So the timing is everything in these flashy flood environments. So the remaining tasks on the gauging that will get us through this contract period is to finish installation of the receive equipment at the bridge street. We have done the structural analysis to locate the equipment on a tower like that. You've got to go through a structural analysis. Others they won't let you put anything on that. So that's been complete. And now we are in the process of procuring the equipment through bids to locate the receive equipment. We are working with neighboring cities to develop interlocal agreements. And I just received one today from Joshua. So thanks to the city of Joshua for working with us on locating a gauge on in your city. As well as we are working with the other neighboring cities I mentioned earlier. So we expect all of that the placement of the receive equipment interlocals and the bids to be done by end of this year. And then early part of next year we'll go through the bids select the contractors and then we'll be able to start installing soon after sometime in the January February timeframe. And then there was installations will take us through about June timeframe. So by the end of June we hope to have all the gauging equipment in place. And those will all be on alert too. I want to move on to the flood warning software. So we made significant progress on the software since our last public meeting. We had issued bids. We reviewed the proposals. The vendors provided demonstrations. We selected a software system. We began contract negotiations with the software vendor and we are in the process of approving the contract through mayor and council approval process. So we've gone through the selection and recommendation stages and we've selected and we recommend the contrails software from one rain incorporated. I want to just talk a little bit about the software system itself. The software is flexible enough to be hosted on a desktop environment as well as mobile units that you can carry on your cell phones. It has data collection capabilities across a variety of meteorological variables. It can ingest both the alert and alert to protocol. So we'll be able to keep up with what's going on in the high water warning system as well as the new enhanced system consisting of the dedicated weather stations. It processes the raw data that's collected by the transceiver unit and then it does a lot of QAQC checking so that you don't provide corrupted data to the emergency responders or the public. There's a lot of good visualization capabilities. It's got an alarm manager to send out those texts and real-time alarms to the emergency responders. And it can also be used to activate those flasher units. Now I do need to mention that those flasher units that you see out on those 52 low water crossing sites, they get triggered automatically. So it doesn't wait for the software at the central receive station on Bernard Plaza to tell it what to do. Whenever the high water warning is triggered, it responds immediately to that trigger event locally. That's the way it's currently right now and we don't plan on changing that. And the control software also has good reporting capabilities. There's a couple of screenshots from the Hurricane Harvey experience. So this is what some of the folk that were monitoring Hurricane Harvey at Harris County were seeing on their system. And we can highlight a table format and show you where some of the intense events are taking place. In this case, those reds are very high events that have exceeded historical standards. And in this case, it's actually exceeded the 500 year events. You can also depict points on a map and show the numerical value associated with those points. You can have a dashboard environment to check multiple variables. It's kind of like what you would see in your car as you're driving. It shows all those indicators in a dashboard fashion so you can quickly diagnose and identify problems. Here's an example of a screenshot from the alarm system. You can drop in a lot of equations to control those alarms in this software. And then ultimately, we'll make the data that's processed by the contrail software available to the public in a form similar to what you're seeing over here. This is an example from Harris Flood Control District that shows what it looked like during Hurricane Harvey. And you can see the tremendous amount of high water events that were recorded during Hurricane Harvey. So what are the remaining tasks for the software installation and deployment? So you can see it on your end. So as I mentioned, it'll go to council date November 14th. And then once the council approves it, we'll execute the contract and then the installation can begin. They'll migrate the data that's currently hosted in the current system into the contrail software. They'll integrate their components along with our components through an integration process. And that's a significant amount of effort, the integration. They will have to come over here and spend some time understanding our system and integrating their system in our system. And then staff will be trained on the use of software once lots of the issues have been ironed out. And then the data will get deployed for us to test out and then eventually made public sometime around a June timeframe. So that's the developments on the software. I'd like to move on to the flood response plan. So the flood response plan is a planning level document that will be undertaken as part of this project. That'll describe the city's flood responses depending on different types of threats, flood threats encountered, likely to be encountered by the city. And these flood threats range from flash flooding through to potential dam breaches to regional level flooding due to levee system issues and riverine flooding. So since we met in April, we've had a stakeholder meeting within the city to identify what that planning level document was going to look like. And based off of the meeting as well as gathering up a lot of the background material and let me just describe what that background material is. So this flood response plan is not going to create anything new in the sense that it's going to integrate and bring in together in one document all the different types of emergency action plans, the emergency management plans that are used in the city by external agencies such as the Corps of Engineers of Water District. We are not going to actually copy into this document all those document we'll just refer to those documents but it's going to integrate in one place the different types of flood responses associated with different threats in one place. So that's what was part of this background research was to gather lots of that material so that we could understand what the different types of emergency actions were. Obviously, when you respond to a dam breach, you're not going to respond the same way as you would do a flash flood and so on. So the effort led to creation of a conceptual framework, how to format that document. And the conceptual framework is using what's called the TDEM-10. This is an emergency planning frame format that the Texas Division of Emergency Management uses. So we will use that framework as much as relevant to host this flood response plan. And we have developed a early draft of that. We are in the process of finalizing the draft and I'm working with the consultants and the emergency management folk to finalize that draft. And then once that draft is complete, we will want to take a tabletop exercise. So this outlines what I just discussed. I did not talk about the preparedness and recovery but this flood response plan will also have mention of preparedness and recovery but the main focus is on response. So here's the TDEM format that will be used to write out this flood response plan. What I'd like to mainly highlight here are Section 4 called Situation and Assumption, which deal with stating the facts on the ground. And then concept of operations deals with the different efforts that are undertaken by the different types of threats. And so that will describe the resources available as well as the application of those resources. And then direction and control deals with how the level of flood threat gets escalated as the threat level gets worse and worse. The preparedness level part of the document will consist of these components that I've listed out here, primarily dealing with educational efforts to keep the public informed prior to severe events. There's a significant amount of inspections and monitoring, particularly with the regional dams. And then mention will be made of the high water warning system that's used to warn the drivers of flood that the hazardous crossings. So let me step through some of what I talked about in a little bit more detail. So the response itself is going to focus on the hazards caused by potential dam breaches of city dams and the regional dams. So there have been over the years emergency management plans already developed for these. So there's going to be, as I mentioned, nothing new in this document. It just integrates the existing emergency management plans that are already out there. The second type of flood hazard that will be discussed will be the flash flooding due to overflowing creeks as well as undersized storm drains. And the third type of flood threat that this document will deal with is the riverine flooding associated with the Trinity River. Here's a map showing you these dams. There are eight city-owned dams in the city as well as the regional dams, which are Eagle Mountain, Lake Worth, and then Lake Benbrook. The Eagle Mountain is managed and operated by the Terrain Regional Water District, Lake Benbrook, the Corps of Engineers, and the city of Fort Worth is responsible for Lake Worth. Here's the different types of flood hazards that have been identified. And the map on the left side shows you the mapping of the flood plains as well as the repetitive loss and flooding from areas that experience flooding due to undersized storm drains. And on the right side, I've showed you a typical type of map that's generated during a flood event showing you areas that experience overtopping as well as incidences associated with those flood events during a flash flood event. So the flood hazard that will be discussed will be the flood hazards due to the Trinity levees, and this map shows you the areas that are protected by the levees. So the first important component will be identification of the hazards. The second important component of this plan is identifying resources available to address each one of those threats, and that's what you see over here, the different types of resources that are available to identify, to work and address these types of threats for the flooding. And the early ones that dealt with the flash floods, in this case, these are the types of resources available for issues associated with the potential breach of the city dams. So the parks and storm water have different dams that they're responsible for monitoring and inspecting, and if there are issues associated with those, those will be immediately forwarded to the Office of Emergency Management and the Emergency Management Coordinator on duty at that time. And then the Emergency Management Coordinator will bring in the police and fire to provide notification to the homes and prepare and execute evacuation plans. There will be coordination with other agencies such as the Texas Department of Public Safety as part of this resource notification. So in terms of flash flood, the third important component is the application of resources to address different types of threats. In this case, I have laid out the main points of how the city applies the resources to deal with flash floods. So the flash floods themselves can range depending on level of severity from level four, which is the least severe to level one, which is the most severe. And the level of activity of the field personnel dictates a lot of the escalation. Not only that, but also the amount of rescues, the 911 calls and all of that is coordinated and assessed at the Office of Emergency Management. And so there's a lot of local level activities that get coordinated at a higher level by the Office of Emergency Management. In terms of monitor application of resources for city dams, as I mentioned earlier, there's monitoring that initiates the distress call to other levels within the city office. Levels of emergency management. Here's what it might look like for the regional dams. Again, the monitoring and observation is the point at which the notification and the escalations begin. And then the Corps of Engineers alerts relevant folk at the various levels of government ranging from state to federal levels and brings in the appropriate resources to address different levels of severity of the dam breach. So once there is a severe event, you also have to recover. And I have shown some of the main points of recovery. The debris is a significant part of recovery. So there are debris removal processes in place. The stormwater management division does flood forensics to understand what happened and characterizes the storm and the flooding extent. And then city forces get engaged to repair significant damage to infrastructure. And then if a presidential declaration is made, you also have to go through a cost recovery to recover the costs. So here are the remaining tasks. So we'll anticipate finishing the draft of the flood response plan by end of this year. It'll be put out for public comment. And then the plan will go through a tabletop exercise. It'll be updated based on the lessons learned from the tabletop exercise. And then that document will be submitted to the Water Development Board and Texas Division of Emergency Management. And then following their comments, the flood response plan will get finalized and go through an approval process with the Texas Division and the Texas Water Development Board. We anticipate completing all of this by June of next year. So I have reached the end of my presentation. And I wanted to summarize where we are right now. We have a good understanding of the current high water warning system, the issues associated with that high water warning system. We've resolved some of the communication problems by resolving the squelch noise issue at the transceiver, which has helped with the data collision problem. Of course, the data collision problem doesn't go away when you're using the alert, but we try to minimize that as much as possible with our current system. And then we have laid out good plans to expand our network and move on to the alert-to-based network. So we'll be working with a hybrid alert-to-alert-to network for a while and then eventually move on to a purely alert-to-based network. As soon as our bids for the equipment and installation are complete, we'll begin installing the dedicated weather station starting in January. The software installation should begin soon in November, and then it should lead all the way to a public website sometime in the June-July timeframe next year. We'll have a completed draft flood response plan by end of this year, which will go through those phases that I showed you just a little while ago, and it'll get sent to the appropriate state agencies for the approval. And then I plan on hosting a third public meeting in June-July timeframe in 2018, and we will have all the components as part of this Water Development Board grant by the extension period in September 2018. Thank you very much. And if you have any questions, I'd encourage you to send me email and please visit the website for updates and keep up with the CD calendar for the third and final public meeting. Thank you.
