last big find: seems like someone didn’t consider existing drainage utilities when putting in this little retaining wall around the Cotton Bowl 😭

this was the only spot I saw where they had to jut the wall inward to avoid covering over a curb inlet cover

~4’ tall concrete retaining wall surrounding the Cotton Bowl that covers half of an existing sidewalk, which has a 3’ curb inlet

the wall shifts backward ~1’ for the width of the inlet cover (as to not block the cover from being opened)

speaking of trench drains, Fair Park has a TON of little slot and trench drains scattered around (though quite a few of them have clogging issues or are partially paved over even)

two grate inlets along a walkway connected by a slot drain with wire mesh to help prevent clogging (featuring another one of those “no dumping” markers)

trench drain hidden behind some barriers along the Esplanade Fountain

one of many slot drains along the roads in Fair Park

short trench drain in the middle of a sidewalk that seems to have been placed much more recently (with pavement that actually slopes towards the inlet!)

I also saw a bunch of these “no dumping drains to creek” markers, but they were all in spanish (aside from “ City of Dallas Stormwater Management”)

though technically an arroyo is a liiiiittle different than a creek

scuffed and dirty “no dumping” marker on the previous combo inlet

a much cleaner (and probably newer) marker next to a grate elsewhere in Fair Park

I went to the state fair with some friends this weekend, here’s what I saw!!

to start, here’s a silly combo inlet using what appears to be trench drain grates/frames? definitely a custom job 😭

combination inlet along a road/walkway consisting of a standard 3’ curb inlet, with four 2’ trench drain grates custom-fitted to the edge of curb

‘CoDallas storm sewer’ inlet cover above the curb inlet, along with a “no dumping” marker

side view of the inlet, showing exposed frame anchors inside the curb inlet

LEGENDARY FIND DURING LAST NIGHT’S WALK: CITY OF DALLAƧ STORM SEWER INLET COVER!!!!!

went on a walk along a trail yesterday and saw lots of swale-based drainage!a couple grate/drop inlets at low points (with tiny little outfalls!) and a pair of curb inlets, one of which had an open back to capture flow from the grass swale behind it!!

a little special type (36”?) y/drop inlet at the end of a swale

a pair of curb inlets, one of which has a special design to have an open back to collect flow from the swale behind it

view of the front of the special design curb inlet and the swale behind it

a TINY (~6”?) outfall for a single grate inlet on the other side of the trail

went on a walk tonight and saw some sad looking combo inlet grates :(

the first one looks like the grate fully failed and they’re just throwing traffic channelizers down there (that one in the structure’s almost 4’ tall!), and the second one lost a vane :(

combination sweeper inlet with a grate that failed and appears to have broken into pieces, with only part of one end hanging from the grate frame. a panel type traffic channelizer is placed behind the hole in the road, and part of another channelizer is lodged in the grate structure

a closeup of the broken grate and the channelizer lodged in the structure. the structure itself seems to be pretty deep since it nearly fits the ~4’ channelizer

another combo inlet grate with one of the vanes of the grate broken off and two more clearly broken. it’s probably a matter of time till this one fails and falls in too (since fewer vanes mean less paths to distribute the force of vehicles driving over it)

✨Happy maned wolf day!✨

Today is international maned wolf day! To celebrate this magnificent creature I ask you to tell a relative, friend or loved one about them! It's the prettiest most leggy animal. They're amazing and deserve our attention. Spread the leggy love ❤️

Have you pet a maned wolf yet?

If not, go do it! Doesn't even have to be me!

other interesting note: the access cover seems to be for “City of [blank]”

that’s a new one lol

went to the movies with bf this morning and saw this funky little y-inlet in the parking lot!

though I’ve heard drop inlet and y-inlet used fairly synonymously, I definitely think this one’s a better candidate for the y-inlet name since it only had openings on two sides lol

a y-inlet placed in a parking lot between several handicapped parking spots, with one of the two openings shown

another angle of the inlet showing the other opening, and interestingly, a access cover that says “Storm Drain City of [blank]”

to be fair, Texas is an awfully big state and TxDOT’s basically the golden standard for roadway-related design around here 😭

ironically I haven’t worked directly on a TxDOT project since I was an intern, most of my experience is just recreationally googling their manuals and standard drawings lol

Arin (drain gang!) @maneybabey.bsky.social · 21d

AIN’T NO WAY

WHY’S THAT???

Arin (drain gang!) @maneybabey.bsky.social · 21d

sure enough, the only reasonable pipe diameter for a single pipe with approx. 21’ (+/- 0.5’) wingwalls (L) was 48”, which wasn’t far off from my 42/48” guesstimate!

the table also shows that wingwall dimensions are in fact dependent on bank slope around the outfall (4:1 H:V in this case)

Arin (drain gang!) @maneybabey.bsky.social · 21d

fun little side note abt this: I couldn’t figure out the exact diameter of the storm drain pipes but knew the wingwalls were LONG (~21’, likely due to the basin slopes) and remembered that CoFW seems to use TxDOT standards pretty often and decided to check there…

Google Earth measurement of the wing wall

TxDOT standard drawings for concrete headwalls for pipes (ignore that it says pipe culverts, I didn’t see a separate one for SD outfalls and it should still be applicable)

fully had to pull over while driving in Fort Worth this weekend bc this silly little basin with masonry stone facades on the wingwalls to match the roadway walls

definitely the spiffiest storm drain outfalls I’ve seen in a while!

wide-angle photo of a part-storage part-conveyance stormwater basin, with concrete pilot channels along the center leading to the outfalls

double (4’x3’?) box culverts beneath a road with a masonry stone facade on the retaining wall

48” storm drain outfall with masonry stone on the headwall and some LONG wingwalls, with riprap around the outfall and the concrete apron transitioning into the pilot channel

36” storm drain outfall with masonry stone on the headwall/wingwalls and riprap surrounding it, with the concrete apron transitioning into the pilot channel (covered in mud and algae)

their recessed brick top curb inlets look so silly compared to typical recessed inlets (more typical inlet for comparison)

side note: the road/sidewalk seems to have gotten improvements not too long ago, you can see where they repaved the localized gutter depression in front of the inlet!!

went on a walk in Addison today and snapped some neat pics as we went!
