A photo catalogue of Zilker Park damages caused by the 2023 Trail of Lights (TOL)

Three areas of concern reported in photos:

(1) Areas of the Great Lawn that have not been re-sodded after ACL and TOL

(2) Landfill fencing damaged with visible rutting - heavy dumpster by TOL

(3) Polo Field, Holiday Tree and pathways damaged by TOL

Butler Landfill revegetated west zone: What exactly is the plan here?

The west side of the Butler Landfill was improved in the spring and summer of 2023. Irrigation was added, and pervious pavement installed to form a Y-shaped driveway for heavy vehicles over the landfill cap which is 5-6 feet of soil over trash.

Location of west side appears in brown/soil color:


The plans show the supportive driveway mats:


However, this photo shows that ACL parked over the entire revegetated zone in 2023:


The revegetated zone has been entirely damaged and the reseeding has begun from scratch.


Was this the intended use when the TCEQ approved these plans for the Butler Landfill "improvements"?

Parks Board members: Please help the general public understand whether ACL's use of this zone for staging will be a pattern of destruction that we can expect on an annual basis. Explain to us if this was the intended use pattern when the permit was approved by the TCEQ.

Follow-up:
On January 22, 2024, I received this information from the TCEQ:

General Information

Texas Commission on Environmental Quality (TCEQ) rules require an authorization for any activity that disturbs the final cover over a landfill. If approved, the applicant can disturb the soil that makes up the final cover over a landfill, install permanent structures (ex. light poles, bleachers, fences, etc.), and install engineered structures (ex. sidewalk, roads, buildings, etc.). Engineered or design improvements over a closed landfill – like parking and staging areas in the case of Butler Landfill – are allowed but the applicant must ensure the final cover remains intact.

 

For Butler Landfill, TCEQ has approved several projects to disturb the final cover.

 

2018 - The July 2018 authorization allowed the City of Austin to remove existing crushed stone material that was above the final cover and replace that material with four additional inches of topsoil, then revegetate the area. Areas west of Mopac were not included as part of this project.

 

2020 – The December 2020 authorization resulted in the City of Austin conducting additional maintenance activities of the existing final cover for the development of the staging area. The maintenance included placement of crushed stone to protect final cover for use of the staging area, minor site improvements such as fencing, grading, and a temporary irrigation system. 

 

2022 – In the May 2022 authorization, the City of Austin revised the type of vegetation used and included revisions for fence foundations, irrigation systems, and stone surfacing over the final cover.

 

Specific Questions

Did the TCEQ approve the use of the revegetated zone for annual ACL staging?

Yes.

 

Is it strong enough for trucks and vehicles to be parked for a month outside of the supportive mats? Is the gravel zone of the landfill of sufficient substrata depth to safely support parked heavy vehicles?

Applications for development over a closed landfill must be prepared and certified by a Texas licensed professional engineer. This engineer is responsible for ensuring that their proposed designs follow common engineering practices and conform to local building codes, along with meeting the TCEQ rule requirements. The engineer is also required to certify that the proposed development will not damage the integrity or function of a closed landfill. TCEQ’s review focuses on ensuring the application meets all TCEQ requirements for developing and disturbing final cover over a closed landfill.

 

Is the grass destruction, re-tilling and reseeding of the zone “routine maintenance” or should it require new TCEQ approval?

Additional authorizations are not required if the City of Austin is revegetating in the same areas and in the same manner as approved in their TCEQ authorizations.

 

Are inspections performed as a matter of scheduled routine, or on-demand? Are inspections made in response to citizen-inquiries like the one I am making today?  Does the TCEQ perform their own inspections of sites like this?

 

While active municipal solid waste (MSW) landfills have a three-year inspection cycle, closed landfills do not have a routine inspection cycle. Compliance investigations for closed landfills are completed by TCEQ as an on-demand activity when a complaint is received or when TCEQ deems an investigation is necessary.

 

Individuals may report suspected noncompliance with any TCEQ rules or authorization conditions to the TCEQ Region 11 Office at 512-339-2929, the toll-free Environmental Violation Hotline at 1-888-777-3186, or online at https://www.tceq.texas.gov/compliance/complaints.

 




A Proposal: Start from scratch and design a green parking lot on the Butler Landfill Bone Yard

The Austin Nature and Science Center directs visitors to park under the MoPac Bridge, a parking lot on TxDoT property that yields about 150 parking places. 

However, this lot is sometimes at over-capacity during ANSC field trips:


Typically, parents who have younger children arrive and park their vehicles to be able to join their school-age children on the school's field trip to the Nature Center:


These are vulnerable visitors to Zilker Park. Could the City provide close-by parking on an environmentally-friendly surface?

If and when the MoPac is under construction (https://www.kxan.com/traffic/south-austin-traffic/ctrma-to-give-mopac-south-expansion-project-update-thursday/) the MoPac Lot may be off-limits for visitor parking.

I propose that the City "start from scratch" to design and build a green surface parking lot over the current Zilker Park Bone Field. The parking capacity might yield 350-500 parking places. It would also serve visitors arrive at the back entrance of the Zilker Botanical Gardens.

Would the ANSC and ZPG approve of this parking lot location?
Please ask them.

01-06-2024 Update on the state of the park after ACL Fest and Trail of Lights

The contract for the Trail of Lights allows them to 
continue "clean up days" through 01-08-2024.





















The Butler Landfill cap:






This parking area is not supported by 6-8" of gravel substrata. 
Why would cars be allowed to park here on the landfill cap?


I hope that the sidewalk extension will continue
over this mud zone, to the crosswalk on
Barton Springs Road at Stratford.


The Polo Field. Trail of Lights operator was allowed 
to use 100% of the Polo Field for visitor paid-parking,
 at $30 per car. The west 50% section that was previously green
is now damaged. Will TOL pay for its remediation?











The Polo Field was used as a temporary dump for Christmas trees.
Austin Resource Recovery will hopefully make other arrangements
when the Polo Field is closed to vehicles and revegetated.


Informal paths between the Polo Fields and the Playscape/Pool
are still compacted and barren.

This path was used as the ACL customer admission queue:



Other informal paths:







Barton Creek banks show exposed tree roots, 
fallen trees and deep grooves where rain
flows in channels downhill into the creek.

The Rugby Field shows patches of sod applied after ACL Fest.




Areas that continue to be compacted and barren:










How did the 2024 Limbacher-Godfrey re-design of the Barton Springs Pool Bathhouse pass review by the Texas Historical Commission?

Take a look at the 1946 historic design of the Barton Springs Pool Bathhouse (BSPBH) -- you still see many of the 1946 elements in our exist...
