Residency Requirement

  • Contractors who cut brush from parcels within the City of Madison can bring the brush cut from those city parcels here to be processed for a fee. Contractors are barred from using the other city-operated drop off sites.
  • Residents or taxpayers of the City of Madison with more brush than what can be accepted at the brush drop off sites may also bring their material here.

Users of the brush processing site will need to prove the brush comes from a City of Madison parcel. Contractors will need to show a copy of the receipt that contains the address from where the material was cut. Madison residents and taxpayers will need to prove their status to use the site as well.

Wood Mulch Information


All Loads Must Be Covered

All loads of mulch received from the transfer station must be covered or enclosed in a vehicle so it can be safely transported.

Mulch service will be denied if you do not have the ability to cover or otherwise contain the mulch to prevent it from blowing out of your vehicle during your trip away from the mulch facility.

You can choose to cover the loads a tarp or other options, like in the back of an SUV.


Emerald Ash Borer Information

The Wisconsin Department of Agriculture Trade and Consumer Protection has certified our brush processing site for safe shredding of ash trees. This means that mulch coming from our site will be free of the emerald ash borer. You can be assured that our mulch will not transmit the emerald ash borer to your property and our mulch can be moved anywhere in the State of Wisconsin.

Free Wood Mulch

Small quantities of wood mulch will be available for Madison residents at 121 E. Olin Avenue only and lasting through the year until the winter snows return.

When entering the facility, the free mulch is located to the left along the fence.  There is a sign that identifies where the small free mulch pile is located.  Please pay attention to the signs and remain mindful of your surroundings so you do not obstruct heavy equipment operating at the facility.

Do not approach the booth near the scale or enter the processing area beyond the booth.

The supply of mulch is limited and it is not guaranteed to be available for residents when they arrive.

The free pile of mulch for residents will be restocked when possible.

Please note that other mulch at the site is reserved for other city processes, such as keeping trees alive while they await planting in the fall, and also for bulk purchasers, like area farmers.
