Fiber Installation Update 

October 7, 2026 

Fiber installation continues to make progress throughout Mattoon. The areas shown in yellow and light blue on the accompanying map are now complete, and the City will begin inspecting these areas in the near future. Fiber installation has not yet been completed in the other identified areas. 
 
As work is completed in each area, Seamless Fiber Innovations will return to repair and restore yards and other areas disturbed during installation. We appreciate residents’ patience as crews complete both installation and restoration work. If you notice an issue related to the fiber installation, please submit it through the City’s iWorQ Citizen Engagement portal. Using the portal helps us document your concern and route it to the appropriate staff for follow-up. 
 
Report a Fiber Installation Concern: https://mattoonrequest.portal.iworq.net/portalhome/mattoonrequest 
 
Thank you for your patience and cooperation as this infrastructure work continues throughout our community.

City of Mattoon Fiber Installation Update

October 2, 2026

Seamless Fiber Innovations crews will continue fiber installation work at several locations throughout Mattoon next week. Crews will continue working along South 21st Street and Stinson Avenue. Once work on Stinson Avenue is complete, that crew will move to the area near 6th Street and Lafayette Avenue, as identified on the accompanying map.

Residents and motorists in these areas may see crews, equipment, and temporary work zones. Please use caution when traveling through active work areas.

We appreciate your patience as fiber infrastructure improvements continue throughout the community.

Help Us Keep Mattoon’s Yard Waste Facility Available to Our Community

October 1, 2026

The City of Mattoon’s yard waste facility on North Logan Street provides Mattoon residents with a convenient place to dispose of residential yard waste. We appreciate everyone who uses the facility responsibly and helps us keep this service available to the community.

Recently, City staff have found an increase in materials that cannot be accepted at the facility, including commercial waste, plastic bags, concrete, bricks, construction debris, and hazardous materials. These items can damage equipment, create safety concerns, and increase the cost of operating the facility.

The facility is intended for residential organic yard waste, including leaves, grass clippings, and small branches. Keeping other materials out helps our Street Department safely and efficiently process yard waste and maintain a clean facility for Mattoon residents. To help protect this community resource, the City is increasing 24-hour camera monitoring and periodic staff checks at the facility. Staff may verify residency and inspect loads when necessary. The City will continue to enforce ordinances regarding prohibited dumping.

Our goal is to keep the yard waste facility open, safe, at no-cost, and available to Mattoon residents. Continued disposal of prohibited materials could require temporary closures for cleanup or maintenance, so we are asking everyone to help us take care of this shared resource.

If you see illegal dumping or have questions about what can be accepted, please contact:

Mattoon Street Department: (217) 235-5171

Mattoon Police Department: (217) 235-5451

Thank you for doing your part to keep this service available for our community.

City Council Passes Data Center Moratorium

September 3, 2026

At Tuesday night’s City Council meeting, the Mattoon City Council passed a moratorium on large-scale data center developments. A moratorium is a temporary pause or suspension of activity.

The moratorium applies to any new data center developments larger than 21,780 square feet, or about half an acre, within Mattoon and the area up to 1.5 miles outside City limits where the City has zoning authority. This size limit is relatively small compared with many large, hyperscale data center projects, which can include much larger buildings or groups of buildings on hundreds of acres.

The moratorium does not stop existing businesses from continuing to operate. It allows the few existing businesses that may fall under the City’s definition of a data center to continue their current operations. However, the City will not accept new applications for data centers larger than 21,780 square feet while the moratorium is in place.

Our community members have raised valid questions about how large data centers could affect our water, environment, health, power costs, City services, and finances. City Council members have also raised many of these questions.

The moratorium gives the City time to study these issues, determining the possible costs, benefits, and impacts so the City Council can make the most informed decisions.

The moratorium will be renewed each year and requires the City Council to take action to change or end it.

Thank you to everyone who has shared questions, concerns, and ideas. We will continue to listen, share what we learn, and work together as we plan for Mattoon’s future.

Tree Replacement Program

For the last several years the City of Mattoon has offered a tree replacement program thanks to a grant from the Lumpkin Family Foundation. Trees have been planted in the spring and fall of the year. We are currently taking orders for trees and residents in the City of Mattoon can now apply to get a tree planted in their yard this fall. We encourage residents who may have lost a tree in the boulevard in front of their home to apply for planting a tree on their property. There is no cost to the property owner.

How does this work? It is really pretty simple, all you need to do is contact the city and choose the type of tree you would like from the list of available trees. City staff will meet with you to look at the location you want to plant the tree and get the location J.U.L.I.E. located. Then the Bloomfield Garden Center will make arrangements to plant the tree on your property probably sometime during the first half of November. We will make every effort to meet all requests this fall, but there is a limited number of trees available. So, submit your request early.

There are two ways to get your order placed by contacting the city. The absolute best way is to use the following link on the city website, iWorQ, and enter your name, contact information, location, and type of tree you are requesting. An alternate method, but not preferred, is to contact the city via phone (217-235-5460) and leave a message providing the same information. Once your order has been received city staff will contact you to go over the location for planting and get the process started.

What tree choices are available for this fall? The following is a list of available tree varieties you can choose from this fall. All are 1½-inch to 2-inch trunk caliber.

• American Hornbeam
• Red Oak
• Red Bud
• Pin Oak
• White Dogwood
• Sugar Maple
• Pink Dogwood
• Weeping Cherry – White
• Breaking Brown Magnolia
• Weeping Cherry – Pink

It is always advised to do some research on the type of tree you want to be sure it is something that will fit in the space you have and provide you with the characteristics you are looking for. Some trees can eventually get too large for the space you have. You should also be aware of any overhead and underground utilities in the area as they can cause issues for your tree, or in the case of your sewer service, the tree can cause issues with it.
