What is the process of requesting a speed hump in Milwaukee? Bauman says that anyone interested in requesting the installation of a speed hump should first reach out to their local alderperson to figure out if there are any measures specific to their area they need to take. However, the general process is as follows: If you want a speed hump, you must start a petition and request at least 50% of support from the block's property owners and/or residents. You must also elicit support from your area's alderperson. With that support, a speed study is conducted on your street. DPW will prepare a cost estimate and send out postcard surveys with those estimates of what it will cost per property. Residents must return the postcards with a vote.
