Edina showcases sidewalk maintenance technology on city TV show
The city of Edina highlighted its sidewalk maintenance operations in a recent episode of "On The Job," featuring City Manager Scott Neil learning about ADA-compliant sidewalk repairs from maintenance worker Matt Batty.
Batty, who works in the Public Works Department's concrete streets division, demonstrated the city's use of modern technology to assess and repair sidewalk hazards. The city employs a Deep Walk application that uses laser camera technology to identify cross slopes, running slopes and trip hazards without manual measurement tools.
The maintenance process prioritizes repairs based on severity levels indicated by color coding, with black representing the most severe issues and green indicating acceptable conditions. Batty said he targets a minimum of 15 repair spots daily during summer months, focusing first on the most critical safety hazards before addressing less severe problems.
Tree roots represent the primary cause of sidewalk damage, according to Batty, who has 14 months of experience with Edina after working 26 years in commercial construction. The city recently purchased specialized grinding equipment with vacuum systems to minimize dust and debris during repairs, allowing work to be completed in-house.
During winter months, Batty transitions to sidewalk snow plowing using trackless machines. The maintenance program aims to ensure sidewalk accessibility for residents with disabilities, families with strollers and all pedestrians throughout the community.

Full analysis
- City of Edina adopts LiDAR-based app 'Deep Walk' to prioritize sidewalk repairs and manage maintenance budgets.
- New city investment in specialized vacuum-equipped grinding technology improves safety and efficiency for sidewalk maintenance.
- Tree root encroachment cited as the leading cause of sidewalk infrastructure damage in Edina.
- City maintenance department balances sidewalk accessibility goals with seasonal snow removal responsibilities.
The major issue for the sidewalks is tree roots. Um you can't stop trees. They grow roots.
We have a super sweet vacuum. The city purchases vacuum this year with this grinding setup, so we can do it in house.
This enables them to enjoy this community. So, that's really a noble calling.

[0:00] Hi, this is Edina city manager Scott
[0:02] Neil and you're watching on the job. A
[0:04] show where we take you behind the scenes
[0:06] to introduce you to the city employees
[0:07] that keep Edina going and show you some
[0:09] things you can only learn on the job.
[0:21] [Music]
[0:34] [Music]
[0:40] Welcome to the show. Today I'm coming to
[0:42] you from the streets, really not the
[0:44] streets, the sidewalks of Adina. And I
[0:47] want to introduce you to somebody who's
[0:48] very important to the sidewalks of
[0:50] Adina. His name is Matt Batty. Hi Matt.
[0:52] Good to meet good to see you again.
[0:53] Nice to see you again. Matt works is a
[0:55] maintenance worker in in a in our
[0:57] concrete streets division of our public
[0:59] works department, but most importantly
[1:01] for this show, he is our sidewalk guy.
[1:04] Uh can you tell the audience a little
[1:05] bit about what you do, Matt, for the
[1:07] city?
[1:07] My job for the city is primary sidewalks
[1:10] ADA inspection.
[1:11] I walk the sidewalks. Um, I use a
[1:13] program now and we go through and it
[1:15] evaluates all the any imperfections of
[1:18] the sidewalk, whether it be cross slopes
[1:20] or running slopes or
[1:21] So, those are those are things that I
[1:22] might trip over or something that's
[1:24] tilted the wrong way. Is that right?
[1:26] Correct. So, we're going to we're going
[1:27] to you're going to show us how how all
[1:29] that is done, right? But what what else
[1:31] do you do for the city? Do you do this
[1:32] is this your 100% job or do you have
[1:34] other things that you do for us?
[1:36] My main focus is the ADA part of the
[1:38] sidewalks throughout the summer months.
[1:40] In the winter time, I do uh plow the
[1:42] sidewalks. I run a trackless machine. Um
[1:45] I I love it. I love plowing snow. I love
[1:47] watching people be able to get out and
[1:49] use our use our sidewalks.
[1:51] Yeah. Yeah. How how long have you worked
[1:52] for us?
[1:53] Uh I've been with the city of Adina for
[1:55] 14 months.
[1:56] For 14 months. So you you must have done
[1:58] this work somewhere else, right?
[2:00] Uh I come from a commercial world and
[2:02] building highrises for 26 years. Oh boy.
[2:04] So all I've ever known was concrete
[2:05] work.
[2:06] Okay. So we're going to see a little bit
[2:07] of somebody else's concrete work. I I
[2:09] guessing today, right? And and really
[2:11] make this sidewalk better for the people
[2:13] that use it.
[2:14] Absolutely.
[2:14] So, you've seen this show before?
[2:16] Yes, I have.
[2:16] And I I've been told you're a big fan.
[2:19] I am.
[2:19] Okay, great. And uh so we're going to
[2:21] you're going to show me how that thing
[2:23] works and how how it makes the sidewalk
[2:25] better for everybody.
[2:26] Correct.
[2:26] All right, let's get to it.
[2:28] So, the first thing we're going to do is
[2:29] open up this uh app we have and it's
[2:32] called Deep Walk.
[2:32] So, what are we what are we seeing? Are
[2:35] we're just seeing what's what's on the
[2:36] street here right now. Right now, we're
[2:38] just doing the we're just looking at the
[2:40] sidewalk with it. So, it has a LAR
[2:42] camera with this. As we start walking,
[2:45] yeah,
[2:45] you'll see the green dots.
[2:46] Yeah. Yeah. Okay. What does that mean?
[2:48] And all those green dots are
[2:49] representing a point on the sidewalk,
[2:51] whether it be height,
[2:52] distance, cross slope. So, if this
[2:54] side's a 8 inch higher than this, those
[2:56] green dots are letting us know without
[2:58] without us having to uh physically put
[3:00] down a level anymore, okay?
[3:02] And measure it. And so, yeah, we just
[3:04] keep walking and it as long as we're
[3:06] getting both sides in. and you're
[3:07] welcome to hold it. And we just keep the
[3:09] sidewalk in the frame. And as we're
[3:12] doing that, it's just showing us every
[3:14] little point. Uh it's not giving us the
[3:16] data yet, but it's it's recording the
[3:17] data where we can have it.
[3:18] Okay. Okay. Come back here now. So,
[3:21] right where you had maybe shaved it
[3:23] before.
[3:24] We haven't shaved that before. We
[3:25] haven't shaved.
[3:26] No. But that's coming up and it's giving
[3:28] us a lot of a lot of extra green dots
[3:30] because it's showing all the
[3:31] discrepancies there. So, it has to shoot
[3:33] a bunch more spots to let us know each
[3:35] individual height variance at that spot.
[3:38] So, Matt, you've done you you've got
[3:40] this picture, you've got the
[3:41] information. What do you take out a can
[3:44] of paint and paint that or
[3:45] I would I would take this as we're
[3:47] walking. I would be marking the trip
[3:49] hazards. Um the cross slopes and
[3:51] everything are kind of a little bit more
[3:52] difficult because we do send this
[3:53] information away to Deep Walk itself and
[3:56] they send us back as a detailed scan uh
[3:59] into color basically. Um, black being
[4:01] the worst, yellow being the least
[4:03] affected, and green being perfect. Okay.
[4:05] Um, it's very hard to get perfect on a
[4:08] old infrastructure. Yeah. Um, but we go
[4:11] through and we utilize the different
[4:12] colors. Uh, so we can utilize our budget
[4:15] the best. So, we start out when I get
[4:16] get the data back, it pops up all the
[4:18] blacks and so I know there's severe
[4:20] cross slopes, running slopes, or trip
[4:22] hazards. So, I would go through and I
[4:24] would mark them and I would come out and
[4:25] I would focus on that first. I would
[4:28] finish those projects and then I would
[4:29] move on to the reds and then I get the
[4:31] reds done and then we work our way down
[4:33] to the least affected.
[4:34] And Matt, what are the factors that make
[4:37] a sidewalk heave or get out? Is it just
[4:40] poor construction? Is it poor materials?
[4:42] Is it trees? What what causes problems
[4:45] for our sidewalk system?
[4:47] The major issue for the sidewalks is
[4:49] tree roots. Um you can't stop trees.
[4:52] They grow roots. roots find little spots
[4:54] and they get underneath everything and
[4:56] as they grow they heave it up.
[4:58] All right. You know what needs to be
[4:59] fixed here, right?
[5:01] Correct.
[5:01] And you said you've seen the show
[5:03] before. So, this is where you show me
[5:05] how to fix this.
[5:06] Copy.
[5:07] All right.
[5:07] Absolutely.
[5:08] Let's do it.
[5:09] [Music]
[5:11] So, Scott, the first thing we're going
[5:12] to do is put some ear plugs in.
[5:14] Oh, yeah.
[5:14] Cuz it's loud.
[5:16] All right. I'm ready.
[5:17] Okay.
[5:21] All right. Scott, what we're going to do
[5:22] is just wheel this up here.
[5:25] And we always want to start on the high
[5:27] side of it. Scott, we'll just kind of
[5:29] turn the machine like this. Oh, and
[5:32] we'll line it up just like that,
[5:33] brother. I'll start it up for you. All
[5:35] right.
[5:37] Here's our throttle. We'll make it go
[5:39] fast.
[5:41] So, this is your lever to bring it down,
[5:43] Scott. Push it all the way down.
[5:48] Now, this is up and down. So, while
[5:51] we're right here, we're going to back it
[5:52] up just a touch. Like right there where
[5:54] it lines up. We're going to drop it down
[5:56] just a little bit until you start to
[5:58] hear it
[6:00] drop. It's dropping it right now. So,
[6:02] now you slowly want to go back.
[6:10] Go back about a foot. See how it went
[6:12] out and stop
[6:19] doing
[6:22] it back and forth as you do it.
[6:26] And it's doing a really great job with
[6:28] that.
[6:30] All right.
[6:34] [Music]
[6:40] [Applause]
[6:40] [Music]
[6:45] [Applause]
[6:54] Yeah,
[6:56] I don't think you should have to do this
[6:57] more than 10, 15 minutes a day.
[7:00] You get a workout, Scott. When I try I
[7:03] try to get 15 spots a day minimum. Um,
[7:07] but there's been days where I've got 20
[7:09] spots. Um, I'll go back and I'll take
[7:11] care of the rest of it. Uh, but as you
[7:13] can see, we already eliminated 90% of
[7:16] the trip hazard where you can now
[7:18] anybody can walk over that without
[7:20] worrying about it.
[7:20] So, so Matt, I've noticed that as you've
[7:22] been doing this, you've been using your
[7:23] foot to you got a good feel as a
[7:26] professional in this field about what's
[7:28] a quarter of an inch and what's a/ an
[7:29] inch and what's just fine?
[7:30] I do. Um um I I come from a family where
[7:34] a little bit of disability in my family
[7:36] um and so I look a lot everything I do
[7:39] um is if someone was walking and had
[7:41] some sort of issue with it Scott
[7:43] and so I just I know when I go by and I
[7:46] drag my foot if I if it if I can't move
[7:49] my foot it's a it's an issue you know.
[7:51] So the other thing I noticed when I was
[7:53] doing this is I expected it to be a lot
[7:54] messier right dust and rocks flying all
[7:58] over the place. So, how come that
[7:59] doesn't How come that's not that way?
[8:01] Uh, we have a super sweet vacuum. Um,
[8:03] the city purchases vacuum this year with
[8:05] this grinding setup, so we can do it in
[8:07] house. But that vacuum takes care of all
[8:09] the dust and debris that pops up, making
[8:11] it safe for bystanders and for myself.
[8:14] Um, it just sucks it up and it puts it
[8:16] into a little bag and I can throw the
[8:17] bag away without any without any
[8:20] touching any dust.
[8:20] So, it's not shooting all over you. It's
[8:22] not shooting all over the neighbor's
[8:23] yard.
[8:24] Correct. Correct. Well, listen, Matt,
[8:26] this has been uh this has been a lot of
[8:28] fun to learn this, right? I knew you
[8:30] were out here doing this kind of work.
[8:31] It's something that's really important
[8:33] to the community when you think of uh
[8:35] the various people that it affects.
[8:37] Little kids and strollers and people
[8:39] that have some kind of walking
[8:40] disability. Correct.
[8:42] This enables them to enjoy this
[8:43] community. So, that's really a noble
[8:45] calling. So, I want to thank you for
[8:47] what you do for the city.
[8:48] Well, I appreciate you coming out and
[8:49] taking a peek at what I do, Scott.
[8:50] Gotcha. You've been watching On the Job,
[8:52] a show that takes you behind the scenes
[8:54] to introduce you to the city employees
[8:55] that keep it on going and show you some
[8:57] things you can only learn on the job.
[9:09] [Music]
[9:09] [Applause]
[9:14] [Music]
[9:18] You know, I noticed that looks a lot
[9:20] like when you tried to mow a golf green.
[9:23] I know. I thought I thought the same
[9:25] thing.
[9:28] Although it's supposed to look like that
[9:30] here.
[9:30] Yeah.
