He's on our board as well.

Nice fine.

I'm talking about your data.

I couldn't think of the name I got it if that is.

Item number five, presentations.

Subitem A, 25-1559.

Presentation summarizing the projects and funds spent to date of proposition six of the twenty eighteen general application bond.

Good evening, Chair, Vice Chair members.

I'm Patrick Wilson, Stormwater Division Manager of the Engineering and Construction Department for the City of Broken Earth.

Um if you could go ahead and put up that uh PDF that is in the so what we're looking at is we're going to do a funding as to what has been allocated as a whole.

So this is what the DAC has recommended to council, and then what council has approved the recommendation on now you see Adams Creek, HP Creek and Elm Creek, they've got zero funds left.

That means we have allocated all the funds.

All the funds have not been spent, they've been all allocated.

So I'm right now in the process of doing some closeouts on some different projects, and I'm also coordinating with our finance department to make sure that my numbers and their numbers match.

So I've asked finance to do an audit of what where we're at to make sure.

Um just so that the committee is aware, every item that is presented tonight will fall within these net uh numbers.

So there's not any question as to whether there's the funding available to allocate.

It is there.

This includes the entirety of the 2018 bond.

Now I do have um some handouts I'm going to give.

It's the project ledger.

It's what the committee has looked at to date.

Very small fine print, it's four-year information.

I'll give some very big highlights in a satellite level view.

Thank you.

Thank you.

Is that can you hear me now?

Okay.

Apologies if the mic wasn't on earlier.

Um as I said, that's very small cramp, but what this is is every application that's come through here.

There's 70 dollars that have been presented to the this committee.

Fifty-nine have actually been have been recommended to council.

Nine have not been recommended, two have been tabled.

With that being said, of those all those projects, 34 have been closed, and those are some of the closeout procedures I'm finalizing with finance, and there could be some fund balance that could get money back in, say Hakey Creek or Adams Creek.

So we're we're working on that, that if there was as an example, say 150,000 allocated for a project and it only encumbered 125, then there's 25,000 left.

So we're looking at is there a possibility how do we get those funds back into that basin?

So we're working on that with finance right now.

Um I've got 13 that I'm going through to the closeout procedure that will be coming before you shortly.

Um the reason they're not before you is because finance and I wanted to make sure that we were all on the same page.

So uh I'm expecting my these closeouts to be on the next agenda that we move forward into the next calendar year.

That is my anticipation right now, and finance and I are pretty much we're tracking to be able to do that.

We've got one project currently in permitting, four in construction, and nine in design.

So that doesn't equal the 70 items, but if you go through and remember I said nine was not recommended, that will get up to your 70.

So as I said on the screen, as I said, this is what's left 567,169.50 cents for broken arrow creek.

Unnamed funds, which unnamed funds can be spent in any of the basins, is 105,384 and twelve cents.

So as we move forward into the next calendar year, we'll get these new projects on here that we are discussing tonight.

I did not put them on there because you haven't made a recommendation to council whether to accept or reject them yet.

So that we'll do that on the next one, and then hopefully we'll have the fund balance where thing we can see where items are.

Um the other item I'd like to just bring to your attention and to those that are listening, that staff is recommending and working with uh city management to recommend to city council that we continue proposition six in the 2026 general obligation bond.

So that recommendation is there.

Um it was talked about a little bit at the public meetings that was had that we held at three different locations.

So bringing it to this committee's attention that we are looking to move this forward and continue this process in the future as well.

Um be happy to answer any comments, questions.

Okay, the unnamed up there, the 105,000, it can be spent in any of these other creeks, is that correct?

Correct.

It can be spent in any of these and also in others, such as Spunky Creek.

And if money, if you have extra money, when I say extra money left over from was committed, and it goes back in, it will go back into its individual creek.

Correct.

Okay.

Those that was if it was allocated out of Hakey, we would put it back into Hakey.

Well, and I can tell you about this particular uh fund uh being on the next bond issue, it's been extremely beneficial to have this in here uh that we able to work with public and private uh sector.

I used to that we had a problem, we had to get on private property.

Uh we just couldn't use this money to it, and I know that uh we've had problems in the past, so we're able to have a solution to some of our problems because of this.

So uh I'm certainly excited about it being on the next bond issue also needs to be passed.

Can you remind us just for those who are in the room and for this board as well?

What was the total amount initially approved by the voters for this?

Uh 5.5 million.

Okay.

And are you anticipating that that will be the ask for the next bond issue as well or uh right now I believe it's right at 5 million.

Okay.

So roughly the same.

Okay.

Okay.

Are there additional funds beyond that being allocated to anything like external planning or otherwise?

So uh in the 2018 bond, we have Prop 5, which is stormwater, which was a little over seven, I think, if I remember correctly.

And then in the proposed 2026 uh bond, there is again Prop 5 and Prop 6.

Right now we're looking at roughly six and five million apiece, so around 11 million.

There are still other funds at times that we can use.

Pat can talk a little bit about uh some of the stormwater capital.

Um one of the other funds that he mentioned, the stormwater capital fund.

That is that comes from when developers come in to work the new uh research that just went in, or that's a bad example because that's actually detention.

But as an example, when they come in, they apply to the city and say, do we need to detain or can we pay fees?

Well, that balance of that, if we say detention, they have to construct a detention pond.

If we say to pay fees because there is an already existing regional pond and it's been taken care of, they pay fees into a fund that's set aside, it's called a stormwater capital fund.

That fund is used specifically for drainage items on city-owned property.

Um, a recent example of what the city has used those funds for was a rehabilitation of a regional detention pond called Park on Florence, and so it would we rehabbed that pond with those monies.

Thank you, Madam Chair, yes, sir.

So in this sheet right here, you have allocated a total of just over 5.8 million.

Is that correct?

That's what it shows.

Correct.

So we have a little bit more allocated than what we actually had in the bond.

That's part of the when he closes it out.

You have to remember allocated, budgeted, spent, available, balancing four pots of money.

And uh Vice Mayor actually said when we get down to available, it goes back into the original pot.

Um we have some we have not overspent, but right now we're a little over-allocated, and if a project or two closes out under, or we've got one that may actually not go to fruition, go to construction, then those monies come right back in.

So we're trying to balance that out with the audit that he talked about.

Any other questions?

Thank you.

We'll move on to item six, general committee business.

Subitem A 25-1560 consideration discussion and possible action to recommend to council to expend funds for drainage design improvements in the Tucson Village 2 subdivision case number 25-018.

Excuse me.

Good evening again.

So the Tucson Village Project that is uh Tucson Village 2, it's the second stage of second phase of Tucson Village.

What where this is located is south of West Tucson Street, 121st, or or not were and west of County Line Road, which is also known as 23rd Street.

So as you see in the box, that is the location.

That is where we are looking.

Um, and it is also the south area of this is unincorporated Tulsa County.

I hit the wrong button.

Thank you.

There we go.

The South area is unincorporated Tulsa County, so it is outside of the broken arrow city limits.

You do see there's a FEMA floodplain.

That is broken arrow creek.

Now that floodplain does show that it's in the subdivision.

But for the committee and for the others, that was actually removed during the process.

The engineer and the developer, as they developed the land, went through the LOMAR, the letter of map revision based on fill process with FEMA in February of 21.

So the FEMA recognizes that the floodplain is no longer there.

They just haven't updated their maps yet.

There's times it could take them years to update their maps, but they have those on file on their website, and it's even on file in the city's offices that that Lomar has been completed.

So as I as you see on here, that box that says drainage swale per NET Engineering Plans.

NET is no exceptions taken.

The plans did go through the city review, and there was supposed to be a swale on the back of that lot.

There was 60 foot of a drainage easement from the property line to the north where that drainage easement was is.

The drainage easement is there per plat, it is on there.

That swale for some reason was not constructed.

Now, as we look at it, there is approximately 46 CFS cubic feet per second flowing onto this site.

The drainage area is around 11 acres or 15 acres.

There's a small discrepancy in that.

As we would go through, if this project is recommended, we would finalize what that drainage area is.

And I opinion is that there is just a ridge or something that might have been missed either by staff as we did it and it got too big, or by the engineer who didn't make it big enough.

So we'd dive deeper into that to make sure that that is uh coordinated and the correct information is there.

So just to take a look, I did take these pictures.

This was this spring, it was after one of the rain events, a few days after the rain events.

And this land, it looks nice, it's nice and green, but it's still soggy.

I had to, I sunk in as I did go through that.

What you will see as you're looking, you're standing on the back property line looking towards the applicant's house and the back property line looking east.

As you look east, that flat land on the second picture on the one on the right, is where the drainage swell is supposed to be.

It wasn't constructed.

For point of reference, that utility pole, the utility pole right here, is approximately 70 feet from the property line.

So that 60 feet fall is 10 feet on closer towards the camera on this utility on this.

So that's where the drainage is supposed to go.

This is what happens in, I wouldn't even say extreme rain events.

Yes, this was this spring, but based on what the applicant has uh told told the city, this is what happens.

It's typical, it does flow onto the land, comes down the hill, and then is good tries to flow to the fence.

The fence then actually diverts the water to the side of the house, and that's the picture you see on the right as it's heading towards the street.

So you could see that the yard in as it heads toward the street, it's eroding, it's down cutting.

Down cutting is that erosion that moves the ground down.

And it's displacing the different soils, displacing the aggregate onto the sidewalk.

You'll see coming up that it's even getting out into the street.

So I have some videos.

This one on the left that we'll go through that one first.

This is the side yard.

As you can see, here's what I was referring to that it is flowing down to the sidewalk.

It does flow across the sidewalk towards that white car, and as we get to the third video, it is getting into the street.

This next video, I want you to pay attention.

There is a little spring before I hit play.

There's a little spring right there.

And for the audience, that is a spring that is bubbled up because of the high water table.

And here you can see that the water is flowing to that fence and then flowing towards the street on the other side of the house.

And this next video, you'll see the flowing through the side yards.

As you can see, it's flowing towards that white car.

It is making a turn getting out into the driveway entrance and taking the sediment out into the street as well.

And this water was supposed to be collected in that ditch that we had uh that I referenced earlier, and then taking west to Broken Arrow Creek.

So one of the things to note is that prior to presenting this to this item to the committee here, staff wanted to have a public meeting with all the residents.

Um we sent out letters to everybody that is along South Winston there that is in the uh red box, and I'd say about two-thirds of them showed up.

Uh the meeting was held on September 4th, 2025, and we informed the property owners of what we what we were presenting this to the committee for recommendation to council.

We also let them know that anything that was done would have to be approved by all of them in order for this project to move forward.

And every one of the resident that was there did agree that they wanted help with the drainage concerns on their back property.

So the public benefit that we do see on this is that we can help mitigate the erosion, mitigate the soils from getting out onto the sidewalk in the street, and also the flooding due to the 15 acres, 10 acres that is flowing onto it, which is in violation of that four lot rule.

Uh staff recommends that the drainage advisory committee recommend to council the expenditure of sixty-five thousand dollars for drainage design improvements in the Tucson Village 2 subdivision.

I'd be happy to answer any questions.

Can you tell us again why you think the city uh missed this to start with?

This was not constructed.

So this was done.

Was it in there?

Was it in the plans?

Yes, it was in the plans.

So the subdivision was platted in 21.

This was constructed in 2020.

So it was in the plans, and it just was not built.

I am not sure why that the this particular ditch was not built, but the contractor at the time did not build it.

Now, one of the things that uh the city management and I have discussed as well is as this is moving through the process to help through it, the city is going to write a letter to the developer and ask some of these questions as to why this wasn't done, how we were going to try to bring them in on a partnership to get this corrected.

Yeah, and at least make sure that we try not to do it again, however, however, it was missed.

Correct.

If I may, madam chair.

So the city inspects public improvements.

Water line, sanitary sewer, storm sewer streets.

This actually is a private improvement.

It did go through the development process.

Um, their engineer, the developer's engineer did design a channel, a ditch, swell, whatever you want to call it, to catch it and essentially in that red box that Pat's showing, uh, convey it to the west into Broken Arrow Creek.

Their contractor did not build it.

We inspect the public improvement.

If it's a private improvement, we don't have bonds on it because it's not ours.

We don't always inspect it.

We have talked to staff uh previously and again reiterated, even if it's a private improvement, which we don't really have the authority over, but if it's a private improvement and it's affecting drainage, we still need to keep our eyes on it.

Uh don't know why they wouldn't have constructed it.

Uh has obviously created a problem, and as Pat mentioned, it's a drainage easement over the utility.

Correct, there's a 60-foot drainage easement.

So by ordinance, we don't allow fences unless it's a chain link over our drainage easements because it blocks drainage.

So none of these could have been built that way.

My suspicion is that the developer realized if I cut a ditch in there, I can't have fences on the back.

Their yards are 70 foot, 60 foot shorter, uh, and it looks shorter.

So my suspicion is that's why it didn't get done.

Um, but we will be having that conversation with that developer, uh, even potentially his contractor because the engineer did design it to go in.

I believe that there should be a cost share.

Um we might be able to come up with a solution that allows the fence to stay.

I mean, if you went and bought a property and then found out you can't do that, that would be very aggravating.

Uh we think we can basically put in a storm pipe and some inlets to drop it in the pipe and get it to carry out to the west.

If we approve it and there's a cost share, what happened?

Does the money just come back into the account or how does that work?

Yes, uh, whatever we I'd hope that we could get that cost share done before we got to construction.

I believe what Pat's asking for right now is just like divine design monies.

Correct.

This is just for design monies, and we would be working on that cost share for the construction aspect as we move forward with design.

In my 16 years here at the city, we've run across nothing necessarily to this magnitude, but we have run across a couple of developments where it wasn't uh tied together too well and water dropping into somebody's backyard, working with that developer.

Uh on that one, they actually paid for the pipe and the inlets, and then we went and constructed it.

This is a lot longer, so we may work out a different arrangement.

I think I know the answer to this question, but I don't want to presume if it was planned and part of the development plans that were approved by the city and not constructed.

Does the city not have any recourse against that developer for full?

We have to basically do what they said they were gonna do when you approved the plans.

So we have complete recourse against the developer who left out public improvements that we would have owned.

We wouldn't own this one, so that becomes maybe more of a legal question.

Um we took no exceptions to the plans that they decided, you know, that they submitted and saying, hey, this is how we're gonna address it.

And we're we're good with that.

But the reality of the situation here, and you can probably see it in that picture.

You can see the tree lines that goes east-west, but you also see the tree line coming from the bottom of the picture, kind of meandering to the north.

I suspect that's a drainage way.

I suspect it's a little creek.

Um they're getting a a lot more water than they anticipated.

Their engineer took care of it, but they didn't address it.

Uh our recourse is really if it was a developer that's continuing to develop, uh, we're gonna scrutinize your plans a lot more, and then we're gonna actually come out and check every little thing, which costs them money every time a delay in construction cost money.

This is a developer that's developed a lot in broken arrow.

I'm I'm hoping that they're willing to sit down at the table and talk to us.

Okay, thank you.

You're welcome.

You answered my question.

You anticipated I was gonna ask it.

So about it.

I second my original statement.

Any other questions, discussions?

The one of the residences here if you one of the residents is here if she's did you want to speak?

Come on down.

I'll ask that you state your name and give your address.

Hi, my name is Leanne Lake.

Um Morris, sorry, just got married.

Um 1909 East Winston Street, and I am the one that turned in the claim with the city.

Um just mind you, those pictures were taken and the videos were taken after I put in um five drains and a pump to pump the water out of my yard.

So I can't imagine how much water would be in there if I but they the builder did come in and put that in after years of begging for something to be done.

And so um that went in about probably 14 months ago.

So the and those videos were taken this past spring, what he showed.

So that just shows a magnitude.

Um, probably about two years ago, two and a half years ago, they did come in and they actually took dirt out of my backyard and built like a pool, which is why you see it pool so bad right there.

Um and I think that's the only thing that kept the water out of my house this past year.

Because if you go back to the videos, you can see it gets within inches of my brick.

So in my backyard, my um porch.

So the my whole backyard is completely messed up.

Were those your red boots in the video?

Yes.

When was your house built?

Um I moved in October 26 of 2022, and I filed my claim with the builder uh the first week of January of 23.

And I fought with him until they sold the company.

I'm not sure if we're allowed to say who the builder is or not, but so they sold it, and then they were like, We're we can't do anything, it's out of warranty, and we're not the company that built it, and so they flat out just said we're not doing anything else, which is why I came to the committee for help.

But the company that purchased them plans on building a lot more in broken arrows.

Does it begin with an L?

No.

Um I can say, I can't I can say it was Shaw that built the house, and then Horton is the new owner.

Who's the new owner?

Horton.

DR Horton.

Okay.

So we're familiar with both of those companies.

Yeah.

It looked like you could catch fish in your oh, I have a video of my son actually practicing with his little fly rod in the backyard.

Oh my god.

So it's it's bad.

And when it does rain, my backyard will keep water, like squishy water where you can't walk in the backyard for three weeks.

And that's with the pumps in the French strains.

So it's pretty bad.

I do have to say I am one of the worst ones in the neighborhood.

Um, the other ones aren't quite as bad, but it's we all have problems.

If if I may.

Do you live middle east?

I my house is the one that has the dot on it right there, the little red dot.

Essentially, where that the tree line is kind of on the phone.

Okay.

So I can read photos.

Do you guys have any questions?

No.

Thank you very much.

Thank you.

You're welcome.

Thank you.

Okay.

Wow.

There's no other discussion.

I'll entertain a motion.

I'll make the motion that we approve uh funds as presented for uh 6A 25 1560 case number 25018.

I'll second that motion.

I'll second that motion.

We have a motion and a second, any other discussion.

Roll call, please.

Hamilton.

Yes.

Wallace?

Yes.

Yes.

Parks.

Yes.

Mason.

Yes.

Henkin.

Yes.

Subitem B, 25-1561 consideration, discussion, and possible action to recommend to council to expend funds for drainage design improvements to a drainage channel located in the 6100 Center Commercial Subdivision.

Case number 25-020.

Good evening again.

That the last week, as we know, there wasn't a quorum, but there were almost 20 people in the audience.

We did go through and have a presentation for everybody that was there that came so that they could see what was being discussed.

Obviously, not everybody was able to make it tonight, but I did want to bring to those that were not here that we went ahead and we did want to inform the public and the applicants as to what was being discussed.

So there was a good attendance and there was a good show of support for these items for all three of these.

Every single one of them had somebody representing the cases.

So the next case that is brought before you is the 6100 Center.

It is a commercial industrial area that is located south of Albany, 61st Street, and it is also west of Olive, which is 129th.

So to get your bearings, you can also see Floral Haven Cemetery on the bottom right.

So that is that's Floral Haven Cemetery.

So that that way you can see where we are.

This site does drain into Hakey Creek.

This would be from that unnamed pot of funds that we showed earlier.

So the request here will have there is enough to cover this one.

What you see, there's a it says a concrete line drainage channel.

Now what that concrete line drainage channel is, it is actually it's called a fabriform channel.

This was done in the early 80s, a little bit in the late 70s, but it's a fabric concrete.

So they put fabric down, put concrete on it, and you'll see the result in some pictures in just a little bit.

That over time, you know, if this was done in 85, that's 40 years ago.

And it is there's some problems with this as it goes through it is deteriorated.

So it was an existing trapezoidal channel in that rectangle, actually that backward C that is right there.

Um it's not in a drainage easement.

Each individual lot owner owns that channel.

This was done in 1985.

The subdivision, the commercial division was platted in 1985.

I am not sure why it was not put in a drainage easement at that time, but it was not in there.

That channel does convey water from the north and even on the north side of Albany, down to, as you can see at the bottom corner.

That there's a creek there, and that isn't a floodplain.

So that's where the water does go.

Um there is an exit existing eight-inch sanitary line, it runs parallel to the channel on the east side.

There's also a utility lines and poles overhead that are also on the east side of the channel.

The other thing on this one is there is no direct access for the city to maintain our sanitary sewer system.

The direct access that we have is coming down all the way from Albany Street through all of the properties through there.

So not really good access into the city's system.

Uh this is fabriform.

This is what fabriform does over time.

It is typical throughout the United States that this is what it looks like.

The water will get behind it.

If it starts cracking, the water gets underneath it.

This it's it deteriorates over time.

Um I want to draw your attention to if you look in the pictures on the right side on the upper corner.

You can see the utility poles.

Those utility poles, they're 11 feet from the top of bank.

Our sanitary sewer, the city sanitary sewer, is in between top of bank and that utility poles, roughly five to ten feet deep, depending on the section.

You can see that some of the channels it's starting to cause erosion, and that's called undercutting as it's doing that.

As the water flows through, the water gets into it, causes problems.

Um you look back, you saw that I pointed out the FEMA.

There's no floodplain on this.

So this is a man-made channel.

And okay, so that okay.

Uh missing a slide.

I do apologize.

The applicant last week brought in pictures and handed out, and I thought I had them up there.

My mistake.

I didn't, I must not have got it transferred over to the ones for our IT department.

But they had more of the same type of pictures of what was here.

It does show that uh more deterioration, more erosion.

There was about six different pictures.

Um with that, one of the things that we were looking at is that we would start with a little threw me off just a moment.

Okay, I know where I'm at now.

So looking at this, the public benefit is obviously it's to protect the sanitary sewer.

It's five to ten foot deep, and as you go through, you can see it's we've got a chance of impacting this if it continues to go as is.

The other benefit is to protect protect those overhead utility lines as the that channel, if it continues to deteriorate, could fall, you could have an impact on the structural integrity of those poles.

So that is the public benefit.

What staff is recommending is that the drainage advisory committee recommend to council the expenditure of five thousand dollars for drainage design improvements to the channel, drainage channel located in the 6100 center of the commercial subdivision.

Again, this is only just design.

Construction is would become at a later date, and this there's also been minor that's there's been starts of talks of even a partnership on the construction on this, so that we don't have that worked out yet.

It has just been a very brief conversation that has been had with the uh 6100 center.

I'd be happy to answer any questions.

You know, this looks like a pretty deep uh drainage area.

Or do the houses are those homes, or is that commercial through there?

That's all commercial.

Are any of their sewers or they go into that their individual sewers?

Is any of them uncovered as deep as that is you know, underneath the concrete or so?

It's an industrial, every one of those buildings have their lateral lines running into our main on the other side.

So you are correct, Mr.

Plummer.

And if you go to some of those pictures, uh see.

There's one.

So if you look up to about where that second utility pole is, you see the white concrete that meant they had to cut to get through there and tie their sewer, their lateral for that building into our sanitary.

Um that's a pretty good location.

Every one of them will have to do something like that.

Well, if I may, the picture you're seeing, it's not supposed to look like that, okay.

It's supposed to look like a trapezoid, just a nice trapezoid.

So Pat did a really good job talking about Fabriform.

Really, we kind of quit using this about the time this went in.

Tulsa had a lot of it over in Joe Creek over by Woodland Hills.

They've replaced a lot of it.

It's just concrete, it's not reinforced, so it's just concrete.

Uh, and you can see it like a quilted blanket, if you will.

They pin it down, they pour the concrete, it's a little stiff.

Then when it cures, what happens is it'll crack between like those little buttons, if you will, it'll horizontal crack through there.

Well, once it cracks, freeze thaw, water gets in behind, it heaves, it's it falls.

You can see the bottom of the channel is heaved up.

Um this would be an engineering disaster to be quite frank.

Uh it trees grow up.

We don't know how many voids could be behind this.

Years ago, and I know the property owners are here years ago.

If I remember correctly, they hired an engineer Barrett Rosenbaum who went out and took a look and had a report on it and basically said the same thing.

He's concerned about voids behind there.

We don't know what we've got.

I I have a couple questions.

I and I may have misheard, but I thought you said 5,000.

Are you 50,000?

50,000.

Um, the fact that this flows into Hakey Creek, is that an issue at all from a from a um from a jurisdictional correct?

Um can you go back to your uh first one?

So the creek this would be a it is a private system, but it'd be a private system that drains into Hakey Creek, so it's should not be jurisdictional, but it is 1,200 feet long.

Is that right?

Yes, almost a quarter of mile.

The creek does go into that little tributary, the creek going through Floral Haven Cemetery is Floral Haven Creek.

Yeah, so it actually it connects to Floral Haven Creek prior to getting into Hakey Creek.

Okay, it would have been an unnamed tributary to all that back in the 80s.

So the for you guys that weren't here, there was a photo last week of one of the panels actually sliding into the creek, it is given way from the side.

So there's a lot of property owner.

Does the property owner have those?

I do have some.

I can pass it out.

Great.

Um, and this would have to come because Hakey Creek has been exhausted, it would have to come from unnamed.

That's correct.

That's what I thought.

Yes, ma'am.

And as you can see, it collects that whole industrial park, and and as Pat said, a little bit to the north side.

Today, we would not do it this way.

If this development was going through the process today, number one, that would be in a reserve, so the entire property owners uh own it have access.

The way it's set up is every property that it crosses that individual property owner owns it.

There would be a drainage over it.

We would uh uh require access to get to it.

And am I correct in assuming that we will have to have a drainage easement?

You are correct in order to make these repairs.

So I think I can't can't remember when uh Mr.

Bright and I went and met with the property owners, but we said that we would require drainage easement.

We'd just write it over and they would have to dedicate access to this.

They had no problem with that.

Mr.

Hall, would you like to come and speak again?

As he's as he's coming up here, I do want to point one thing out that I did not say.

This was done in 1985.

The City Broken Arrow's first design criteria started in 1994.

So this was prior to any current design criteria, actually, prior to any design criteria in the city of Broken Era.

And it shows it by its age by that too.

Lack of requirements.

And there were many more last week.

There were but uh I just want to go through a few of the points.

Um while you're looking at that, it we have 20 acres in the development.

Uh there is a detention facility is required up there at uh Commerce Crossing, which is in that uh at the corner is kind of what it looks like.

But back at the back, there is a drainage uh uh a containment for runoff, and it ends up flowing down past the cemetery, and guess where it ends up in this channel.

All right, not right at the beginning, but down about two-thirds the way, half two-thirds down the way, it actually flows into this channel too.

So effectively, we're not just handling the 20 acres and it's a private easement, and I know you hear this stuff all the time.

So no matter what home or subdivision you're dealing with, there's always people above it and below it.

So, but but it is important because the end of the drainage channel is handling more than the runoff of 20 acres.

Um we have 60 owners, excuse me.

60 owners and about approximately 80 companies that are located.

I've got the note 88, because by my count, that's how many actual spaces we've got in the center for for companies.

Uh some of those are multi-tenant buildings.

I didn't go check every one of the doors to see if someone was in it, but it's 80 plus companies that we've got there.

Uh hundreds of employees.

I think solar turbine probably tops that number.

So, you know, solar turbines down at the south end.

You can run the numbers, it's more than thousands of dollars every month that that this group feeds into the city in taxes and stormwater uh runoff fees and that sort of thing.

Uh we've already hit on some of these 85.

It's it's an old piece of equipment, 40 years.

I'd say this too.

You saw several pictures and maybe some more now.

Uh the owners have spent uh money every year trying to kill the vegetation that naturally comes up in this drainage ditch.

And and so we've always thought we were doing our part of the responsibility to try to maintain it because obviously once you get those things perforated with plants and that sort of thing, you're gonna get water behind the uh uh concrete lining there.

Uh the only thing I'd say we appreciate the chance to participate and hope that you will recommend us for approval, and I'm sure we'll hope we can work together on actually getting it fixed after it's designed.

Thank you very much.

Yeah, oh yeah, any questions?

Any questions?

Okay.

Thank you again for coming.

You betrick I have one more question, which is I understand these funds are for the actual design.

Have you guys had any discussion about besides removal of all that crap, you know, what that design would be and how you would handle that runoff because there's going to be substantial runoff going downstream, what I would call downstream from there as well, and that it's gonna have an impact somewhere.

So any of the design, no, we have not had discussions as to what that design may look like as of at this point, but any design would be in accordance with our current design criteria manual that we would do the analysis as to what is to that point today, and we would not increase that flow downstream at all because we want to make sure that we balance it so that we don't adversely impact anybody downstream either.

So there might be a combination of things that has to be done to slow the velocity down well as we look at it as it discharges.

That would be a part of the design process.

Have you guys identified the engineering firm that you think makes best sense for this?

I don't need to know who it is, but just wondering.

I have not.

I I know you've had some conversations.

They've had to deal with difficult things uh like this in other communities.

So we do have someone in mind.

Thank you.

And if I may, madam chair, I would add just two things.

One, um, I came here in 2008, and I think immediately got involved in this, and it had been gone many years before I came here.

The property owners out there have been very patient, very good to work with.

Umbody would want to inherit something of this magnitude.

And I just want to thank you for the ones that are here, and Mr.

Hall, you guys have been wonderful to work with.

Then, number two, and probably as important, if not more important, the whole point of the 2018 bond prophet to just address things like this.

When we went through it, I didn't even think of 6100 center.

When they called and asked some questions, I'm like, oh my gosh, this is perfect.

So I agree with staff, I would highly recommend uh approval of this.

Any further discussion?

Entertain a motion.

I'll make the motion to approve the funds for case number 25 dash 020.

I'll second it.

Any further discussion?

Roll call.

Hamilton, yes, Wallace, yes, pickle, yes, Parks, yes, Mason, yes, Hendrix.

Yes.

Subitem C 25-1562 consideration, discussion, and possible action to recommend to council to expend funds for design of drainage improvements and protection of existing city sewer trunk line at East Natchez Street and Lynn Lane, South 177th East Avenue, case number 25-019.

Good evening again.

This project, as it says, East Natchez Street and Lynn Lane.

This is in the uh south part of Broken Arrow.

Natchez Street is as you can see there, that upside down L.

Lynn Lane, 9th Street, that goes all the way down into our wastewater treatment plant.

The golf course that you can see on the side, that's that's Indian Springs Country Club.

So that that's the golf course just to give you an idea as to where this is in the city.

The two areas that we're talking about is that upside down L and Natchez Street, and then the pond embankment.

So there's two areas that we're discussing in this as we go through there.

Um for a point of reference, the applicant's house is in the green box.

So he's right in the middle of the two.

And this is part of it.

As you can see, the where the floodplain is, that's broken arrow creek.

So the all this water does flow into Broken Arrow Creek.

It's an unnamed tributary.

It is not a blue line, not governed by the Corps of Engineers, uh, but it is unnamed.

And then we've got Broken Arrow Creek there on the right side of the screen.

It does that what I say that 60-inch sanitary, that it that is in the berm of the pond.

So you've got the pond, you've got a berm, and you've got broken arrow creek.

There's a manhole right in the middle of that, and that is just as we went through this 60-inch line is the main line that feeds the uh sanitary sewer treatment plant on this to the south side.

So majority of the sewage in broken arrow flows through that line.

And that's something we really want to think about on that, but that's another reason why we're coming to this.

Is a good it's something that the city would like to see protected.

These are pictures during the during the spring rain.

Um this was an intense event.

This was two inches, two and a half inches in 45 minutes.

What that equates to, you you hear people talk about percents, you know, a two percent event, a one percent, one percent is a one 100 year, two percent you think of a 50 year.

This I did some interpolation between on some graphs from uh the national from NOAA on this, and it came out to be about a 45-year event.

And so, which if you think of percentage, it's a 2.2.

That means that in any given event for that year, there's a 2.2% chance of exceedance of this.

This is a very intense event.

Um, I'd like to remind the committee earlier this year was brought before you an area in Indian Springs on another portion of the golf course where the road was completely flooded, and it was I mean, it was deep, it was you know six, seven feet deep.

I'm gonna estimates based on what I saw.

That was brought before you.

This is the exact same rain event.

The one on the left is the pond, the one on the right, that's the discharge.

The gentleman is standing on the discharge that berm that we talked about of where it's going at.

There are three um black corrugated pipes that are going through that berm right now.

Uh we've got some videos that the uh nope, these are still the still pictures, the videos are coming up.

He took still shots from his videos.

So this is also the pond, the one on the left looking down.

What you see in the middle, that's overland flow from Natchez.

The videos will show that really good, but that's overland flow.

When he constructed his house, he put this berm up.

And for the audience, this there's a berm right here.

So the water flows from the west to the east, it hit that berm and is actually overtopping it.

The picture on the right is also looking back into Broken Arrow Creek.

For a point of reference, you see the flagpole in the back on that right picture.

That flagpole is actually in a floodplain.

So that gives you a just a general reference.

So that area, way in the back, that doesn't surprise me to see standing water.

That that area is actually in Broken Arrow Creek floodplain.

This is a this picture is also for reference.

This picture was taken in let's see 2021.

This picture is also a DAC project.

You see the culvert that is right there.

That culvert discharged into this pond and went straight into and eroded off this bank.

So for the audience, it hit right there and it was eroding that bank.

So that water was coming through the city's culvert, and the velocity, the protection when the culvert was built, was not long enough to take that into account.

And so that was already addressed by the DAC at a previous, it was I said the improvements were complete in 2021.

I do want to make a correction for the record.

In the packet, it was stated that the culvert, the crossroad culvert on 9th Street was a part of this project.

It was not a part of that project that the DAC approved.

That was a typo on our part.

We got a little too ahead of ourselves.

That was not a part of the project.

The riprap at the protection was.

So we weren't a part of it until 84.

So we had just got into that area.

And our design criteria again, it started loosely in 94, and that there was some ordinance in place, and about 2001 is when the first design criteria really started.

It took that 94-1 and actually amped it up into our current model.

There's been a few revisions since then, but so that's the timeline of our drainage.

The public benefit on this with again I hit the wrong button.

Thank you.

So we'll go with this one for right now.

The public benefit on this is on the Natchez one to look at analyze the drainage area, put in a collection system to help mitigate that overland flow.

Natchez was originally designed as a drainage channel.

Typical from 80s to before.

That is a typical design method across the country.

What we'd like to do is look at the area.

What can we pick up?

How can we help mitigate this?

Get that into the channel that is right here, that crossroad channel, and that way that is contained.

We're gonna do the best that we can with the utilities in that area.

Can we get that 100-year event?

I don't know.

But we're gonna do the best on this to mitigate it so that on normal rainfall events, we won't see what we saw in those videos.

The next is to analyze the downstream berm that is acting as a dam on that pond, and let we want to see the outlet structure.

How is that outlet structure performing?

Is it adequate for the flows that are coming into it?

Is do is there a need to do an upgrade?

And that is a part of what we're looking at doing.

So the public benefit is to mitigate the flow across from Lin Lane and on Natchez to make the roads more passable, and also to protect to look at the design for protection of the 60-inch trunk line sewer.

So the staff is recommending that the drainage advisory committee recommends to council the expenditure of 75,000 for design of drainage improvements for the protection of the existing sanitary sewer trunk line and for the area at Natchez and Lin Lane at that intersection.

I'd be happy to answer any questions.

So is the sewer line the pond embankment?

Um that is that's what flows into Broken Arrow Creek.

Okay against Broken Arrow Creek.

It's up against Broken Arrow Creek.

Yes, it this the sewage line parallels broken arrow creek.

Okay.

And then flows into work being planned at or related to Broken Arrow Creek?

No.

Gotcha.

We just replaced the sanitary search line a few years ago from the Lin Lane plant, which is probably half a mile or so south of this, towards the bottom of the page, all the way to 111th, and we're now re uh redoing the next segment as well, all the way up to 101st.

That's under construction right now.

Cost 16 million dollars to replace about four, four and a half miles.

Upsize different materials originally was built in 83, then replaced just recently.

We just want to ensure the safety of that.

If that segment went down, we would have a problem here at City Hall.

Because everything from this part of town goes to Lin Line.

And that is a 60 inch 60-inch diameter.

Correct, five-foot diameter pipe.

I can almost walk through it standing up.

We go.

Any other questions?

And I think Pat did a really good job.

You're kind of like, well, what's the public benefit?

The Sanitario Sewer, but the street passage as well.

These two are tied together.

Uh you could take them separately, they're tied together.

Indian Springs, there's there's a pond there, but there's no detention.

There wasn't any detention.

I think it went in in 71 as a golf course.

This drains the lakes at Indian Springs on the north side of Jasper.

It drains Indian Springs Manor, which Pat just talked about on that street going north.

It drains maybe even the Oaks at Indian Springs, a little bit of that, and then the Indian Springs golf course.

Um the city of Broken Arrows dealt with the not this particular property owner, but the previous property owner in this location for many years because of the drainage that's coming through there.

As Pat said, we just upsized the culvert.

We did not increase the runoff, but we have upsized the culvert and made some improvements.

We've got a construction project going right now on that'd be eighth and Natchez.

Uh fix upsizing that culvert.

This piece here, if we can collect the runoff, you had one picture.

Can you go back to that one picture?

Let's see, keep going through one of their porches.

The video or the video on the right.

Is that was that a video?

Well, I've got it both.

That that picture on the right with the fire hydrant, that is taking a whole lot of the golf course that's to the south of this.

It's on a hill coming down right by that person's house.

Uh 20 years they've been dealing with with that.

Um it's not a big enough system to pick it up.

There was it wasn't sized back in the 80s.

We can size it today, put in a couple of other inlets, and I think we can address this in a lot better way.

Well, part of that flooding though, this is a question, was supposed to go into the street.

The street was working as a uh storm shore.

To counselor or vice mayor parks.

Um it was very common in the mid to late 70s to have the street as a part of the conveyance system and then the pipe underneath.

Uh Pat mentioned 100 year.

There's also a five-year, so a 20% chance.

The pipe would be sized to carry the five-year event, and then when the if the storm was greater than that, it just went into the streets.

You could actually go beyond the curbs.

So this was a a common practice.

Broken era just utilized the same practice that other communities used.

Nobody uses this practice anymore.

Um, it's just it's too much rain.

So we're trying to keep it 100-year in the system now.

Um, that's what our criteria calls.

So, yes, that was kind of a common practice for the mid to late 70s, and I'm sure we just carried it on over.

Any other questions?

I'll entertain a motion.

I'd make a motion that we approve case number 25-019 for $75,000 for $75,000 uh in engineering fees.

I'll second that.

Any further discussion?

Roll call, please.

Hamilton, yes, Wallace, yes, Pickle, yes, Parks, yes, Mason, yes, Hendricks, yes.

Item number seven adjourn.

I'd make a motion to adjourn.

I'll say them that I'm good at that.

Roll call, please.

Hamilton, yes, Wallace, yes, pickle, yes, Parks, yes, Mason, yes, Hendrix, yes.

It was been a lot of money, hoping.
