Milwaukee has had a managed urban forestry program since 1918. We prune, plant, and remove trees annually and have done so since the turn of the century. We know a lot about our urban forest. We keep an inventory identifying species, location, size, diameter, maintenance history, and more. We know that in any given year, we will lose about 2 percent of our population of 194,000 trees. So 3,500 trees will come out of our population annually and be replaced.
We have a pretty good handle on the supply chain on our end. Urban tree removals represent a cost for processing and disposal. With the influx in emerald ash borer, the trend to buy local, and a goal to reduce costs, we set out to find a better, higher value utilization of urban wood than woodchips and firewood. Sending our trees to an urban wood sawyer saves taxpayers $80,000-$100,000 per year.
Also, we are in a unique position in history to launch an urban wood industry. First, we have the influx in urban wood inventory because of emerald ash borer. The other catalyst is the emphasis on locally-grown food and locally-sourced materials. People want to know where their food was grown, how it was grown, and if it is safe. The same is true for wood. It makes little sense to have wood from the West coast when it is available from your own backyard. I am convinced that the demand for urban wood will grow once the public is aware of such a reliable source they can access.
Any volume of wood we produce could be diverted to a higher end use such as lumber or another forest product.
We are not yet selling larger projects to contractors and architects. In fact, we have had to turn projects down because we currently cannot work in large quantities. We are working on a grant to get a new kiln, which will increase our capacity and rack space. Offering larger quantities will better help us engage with the design community, including flooring, paneling, and larger residential projects.
Urban wood is not much different than a traditionally forested product, but it does have a lot of challenges related to its handling and processing. We have a large staff who has the skills to remove trees and transport logs. Since 2011, we have worked with Kettle Moraine Hardwoods, Inc., in Hartford, Wisconsin. We send them containers with a 30-cubic-yard capacity filled with logs and branches for free. All we pay is $25 per ton for the transport, where the alternative cost for disposal was $47 per ton. They determine what can be milled, chipped for boiler fuel or chopped into firewood; dry it; and sell it on their own. We send 2/3 of our urban wood to Kettle Moraine Hardwoods and about 1/3 to Bayview Lumber Company in Milwaukee.
Our arrangement with Kettle Moraine Hardwoods provides the City with free dimensional lumber for use in special projects, such as conference tables crafted by a city carpenter and placed in several city offices. These unique pieces of furniture become conversation pieces for city officials hosting dignitaries and residents, and help to promote Milwaukee’s sustainable use of urban wood. We’ve also used lower quality dimensional lumber to build flower and urban gardening beds. We strongly believe we can promote urban wood utilization just by having stair treads, accent walls, moldings, paneling, and furniture in various residential and commercial buildings throughout the city.
We need standards for specifying urban wood that planners and builders can use so they understand what urban wood is and, most importantly, how it is different from traditional dimensional lumber. There are no best practices in place for private companies and municipalities that would be interested in harvesting trees for urban wood. The people who are currently working with urban wood are learning through trial and error.
There are a lot of pieces coming together, efforts in the works for many years now are coming to fruition:
This is the time to be part of the process.

The Urban Wood Network is made up of individual and organizational efforts in Illinois, Michigan, Missouri, and Wisconsin, working in cooperation to connect and enhance the full circle of sustainable urban forestry. This website was created as part of the grant project, Bringing Urban Forestry Full Circle: Localized Approaches for Capturing Value and Enhancing Public Benefits from Urban Forests, funded by the U.S. Forest Service. The Urban Wood Network provides equal employment opportunities (EEO) to all employees and applicants for employment without regard to race, color, religion, sex, national origin, age, disability or genetics.
