 notes before we do. If you don't mind if you're able to mute your audio and we'll have time at the end for questions after the presentation and if you are able at a computer or able to on your phone to put anything in the chat feature of WebEx you can do that and we can try to look at that at the end. The presentation is being recorded and will be posted on the city's website so you can view that afterwards or share it with friends and neighbors. So with that we'll go ahead and and get started. I'm Mike Crenshaw the project manager for the design and construction of the West Creek Channel Maintenance. We have others on the call with us here. Justin Naylor is with the city footwork as well and he's leading our effort. Linda Young is our program manager and she's on the call as well so there are others that are joining us from the city so whatever questions that might come up you can email me or and I'll have my email and contact information at the last slide but we'll have that available for you as well and I did get a message that someone else was trying to join and they were having a bit of problems so I might have to get in touch with them. Okay so we'll go ahead and get started. So this is this is the West Creek Channel so I'll just give a little background on the area. Most of you hopefully got the mailer or saw this on a tweet or the city's website. This is south of Loop 820 down McCart near the intersection of McCart and Altamesa. There's a couple of channels along there. If you live along this area you're very familiar with these, know where we're at. So we're calling them three channels. It's really one tributary coming across McCart and then one long channel throughout the Mesa. These actually flow from south to north and the lowest one along Altamesa we're calling Edge Cliff. The one coming under McCart we're calling Cross Baker and the one along Woodmont Trail we're calling West Creek Channel. That's just for our design purposes. So we'll go through some of the needs and some of the work that we're looking at doing. So the first bit is we'll talk about what the needs are. The areas is older. The existing channels have aged fairly well but there is and it has become time neat for some needed repairs and maintenance. Mainly some of the paving of the side slopes of the channels and what we're calling the toe which I have a picture of that. We'll look at that. That's kind of down cutting along a couple of the channels and just overall some general erosion and the channel deterioration that has happened in these three areas. So or these areas. So I'll have some pictures specifically that address those but just so you have a general idea of where we're at and what we're hoping to accomplish with this project. So let's look first at the West Creek Channel. This is kind of east of West Creek Drive and it flows towards the park along Woodmont Trail and this area is what we would call a trapezoidal channel or the shape of it. It's like a trapezoid and some concrete on the sides but generally the area underlying geography of the area has a limestone bottom so the bottom is fairly stable. It was just a channel to convey the flows and keep the banks from eroding and over time and these are many years old but you can see in this picture and several of these pictures over time that some of that deterioration has taken place in the channel you can see on the far left some of the paving that's in the over banks and along the flow line or the the bottom of the channel some sediment has built up over time but potentially here's we're pointing to in the middle some of the bottom where this bank paving meets the flow line of the creek there has been some deterioration over time. This is what we're calling the toe of that paving that comes down and meets where the water is here in this picture in the creek and so you'll see in some of our proposed repairs that we're coming along and fixing or connecting the toe back into the underlying bedrock. So this does a couple of things of course the maintenance effort here is to extend the life of this paving to stop further erosion and deterioration as well as to make sure that this other piece is a concrete here along the slopes don't continue to deteriorate or get undermined over time and so that's the the main effort along West Creek channel and that portion extends again from West Creek so welcome Michael I saw your message so I'm glad you're able to to join us here so this is West Creek channel along from about east of West Creek up to around the park area and so those are the main repairs going on through that location the other segment that we'll talk about is from out to Mesa north up to West Creek Drive this section has a few of those tow repairs that we were pointing out that we just talked about a few of those and another problem along this section is a good stretch of that paving along that bank has actually deteriorated to the point that it can't be saved so we're looking at replacing as minimally as as little as we can but what's needed to be replaced along that bank and you can see the water again is flowing from south to the north so that takes a direct hit from that water coming out of from under out to Mesa so that needed to be seen to as well as some of the tow repairs this section is unique in that it's the only piece that we're hoping that's the only piece that we have to do these what we're calling full panel repairs along that paved embankment you saw several of the other areas where there will be tow repair that's at the area where it meets the creek bottom and so that means the rest of the panel is in pretty good shape we just need to keep the water from undercutting or getting under those panels along the bank and so that will will be a part of this section on edge cliff channel and the last little bit that's what we're calling the third channel that's really coming out from under mccart here this is from the cross Baker cross Baker Park water is flowing from left to right across your screen this area is commercial as many of you know along mccart and then there's some apartments and then there's some homes as well so there's a mixed use area around this part of the channel there is an existing maintenance ramp entrance the city has that comes off a West Creek drive to get to the channel for maintenance etc this section or this piece has some some different types of repairs and and challenges that that come along with this it's much more confined you can see this it's not as wide as the other parts of the channel and through this section the repair types will be a little different some of the efforts will be to go behind where the channel bank is eroding and put a curtain wall or a wall underground here that will prevent this flow line along the toe of the channels from continuing to erode back some of this is a natural process in the stream that takes place and so the city will do this to protect the integrity of the channel keep it from further eroding back and hopefully stabilize the channel over time and so we are coordinating a number of other elements with this the floodplain management group to make sure that we don't have any adverse impacts to floodplain management as well as the water and sewer department as the sewer lines obviously have a flow through here and many of them are in in this area along the creeks as well as tarant regional water district has some lines through here so we're coordinating with tarant regional from an environmental standpoint we also coordinated with the core of engineers to make sure that the habitat the wetlands area etc are protected and ensured that that there's not a loss of wetlands along this these channels so those are the overview of the three channel areas that we mentioned again we're looking at this area to the south from out to Mesa up to west creek the area from west creek up to the west creek park crossing here and then a small section from the cross baker park that comes under mccart flows across here to the other channels so that's our that's our general area for this maintenance of the channels again we're looking to mitigate some of the erosion these channels are are getting up there in years of age they've done well but it's time for some some needed maintenance and that'll be a quick again is that concrete paving along some of the slopes and then that toe or the bottom where the side slope meets the bottom of the channel so a couple of the milestones and this is subject to change but tentatively right now we're on on track to complete our design this late this spring early summer and to be able to bid put it out for contractors to bid on and then we get those bids back evaluate those bids select the the most qualified and contractor and lowest bid and then hoping to get that to council sometime late summer of 2022 and then anticipate a construction start around fall of 2022 again that's all subject to change but that's our our tentative scheduled now and anywhere from 18 to 24 months on construction that depends on the weather the winter how harsh or mild the winter may be how wet our spring may be because this is in work in the and along the bottom bottom part of these channels it doesn't take much rain to to cost us a day or two of work so that's why we have a kind of a large gap there between the when we start when we finish we have to allow for for the work conditions especially when we're in here along the bottom of the channels this is funded through the stormwater revenue bond and right now the construction estimates that we have today are in about the four million dollar range excuse me so that will be again determined later this summer when we actually put it out to bid and and open those bids and look to select in a contractor here so that is the channel maintenance that we're looking at along here again we're about midway through so we're about 60% now and hopefully we can move along here pretty quick to our 90% and final design and we which wanted to give everyone an update an opportunity to see the project to see what's coming and to ask questions so at this time that's all I have to present and here's my contact information and this is my cell phone number you can take that down email address you can feel free to email me we will also again as we said we have this is being recorded so we'll have it up on the city's website for others to view and for you to share and watch afterwards there will be should say there will be future meetings coming up as well as we get closer to construction and then before we actually go into construction that have details on it so at this time I know we have a couple of call-in users and you can unmute yourself if you want or if you're muted or if you're not and I think it shows on the screen is calling user two I don't know if you have any questions if you do you can ask now I didn't see anything pop up in the chat hey Mike I got a question okay okay um just going off the mailing I received last week um it shows you know I don't it shows the certain things are highlighted is it just the things that are in red that you're primarily wanting to work on correct those highlighted areas um there's different pieces and parts through that some of the channel is good and in good shape and some of it needs attention and so we and you'll be able to download this this recording later for a closer look and you can pause it but each of these images here we kind of show the area highlighted where the the deterioration is either undercutting getting under that existing side slope paving and needs replacement or in this case where these panels along this is just north of Alta Mesa Boulevard where these panels the whole panel had already eroded too far underneath and we couldn't save the panels so we have to go back and and repave the whole panel but the rest of these we're hoping just to be able to get in it and do what we call the toe repair yeah and just to make sure it doesn't uh further erode that paving along the sides of the banks of the channel okay I have a question that might be a little bit outside of the scope of this project and maybe it's just best if I just call you some you know for about a year now I've been thinking about you know finding out who finding out who to call about something and uh but you know that's something to do with that um you know uh South Hills, Walgreens area there's a just a little thing that strips through cuts through Shasta cuts through Jenny and then connects to that bigger stretch that you guys looks like you're going to be doing some work on and um so would you recommend I just call you maybe another time and yeah um sure uh Justin and I can uh I think you're talking about right through here you're exactly yeah sure no um yeah Justin Naylor and myself can you can email me or text me your email address okay and uh and I'll set something up with you yeah it was one of the things you guys did somewhere I'm gonna guess 10 years ago you guys did that Gideon mattress or whatever they call it uh and everything's good it just changed the um it changed the landscape of I'm right on that creek you know so it kind of changed the landscape where it's a little more I'm getting older and it's getting kind of I like to keep my easement trimmed and you know groomed and all that where maybe others don't but uh just kind of like wanted to ask you probably going to be more uh advice than it is asking the city to actually do anything but anyway so I'll go ahead and I'll text you my email address and we'll we'll just set something up it would be something where I would where I'll hope one of you guys can come out here and I can just kind of walk it with you a little bit sure okay yeah well I appreciate your time thank you all right take care sure hello I have a question sure hi I understand you know the maintenance is going to be due to the deterioration and the erosion and all that my home is on Jenny it backs up to that creek so when the repairing and all of that begins um for those drainage channels is there any concern that I should have about flooding it's just heavy rain uh or anything like that and I'm not sure you can answer that question but that's my only concern sure no um these uh couple things we've we've done uh the city requires that we do some analysis to make sure that nothing we do has any kind of increases or adverse impacts um on any properties there but also as you pointed out during construction is too the contractor will obviously will you know they they regularly pull their equipment outside of the channel and not leave large piles of debris etc in the channel that's kind of part of their work uh processes so they won't be like piling up large amounts of material and then leaving it in the bottom of the channel because that could have like you say temporary impacts um and so they've got some staging areas outside of the channel for each section and as well as for each segment of uh the construction areas and then you know we'll have some specific guidelines for them during construction and obviously they wouldn't leave equipment down there because because most of our rains come at night right so they and then obviously during that wet season it'll be only able to work as they're able to get into the channel and do the work so okay great thank you sure and and we'll have another meeting like I said we'll have a probably a couple more meetings on this as we get ready to go to work and then as we actually get started working um and so you'll have not only our contact information but then even as it goes to construction there'll be a city inspector on the job and his his information will be available as well so all right thank you that's good questions let's see any any other questions that we should cover for our meeting okay well we are 60 percent so we're still some days out here from from having final plans and and then again being able to to actually advertise it to bid and get in contractors interested in it so we'll we're available let me go back to my contact information if you have any questions you can call or text or email me and we'll get a response and get or get in contact with anyone that that needs we need to and then recording or excuse me the the presentation has been recorded so that will be available uh on the city's website we will also get a page set up for this project so you can search I believe just said we could search west creek and that should pull it up and that will will take you to a link to watch this recording afterwards and you can share that link with other neighbors and folks that you'd like to to watch it and then of course we're available via email or all we can be in contact there is no other questions don't see any I think that about concludes it but this evening thank you all for attending have a good evening
