District Mapping Tools
The City is in the process of moving from an at-large election system to a by-district election system. To draw these new districts we need to hear from you as it’s important to know about your community so that the district lines can amplify the voices of residents.
We need your help to build a community map and our new city council district map! Please use the online tool called DistrictR to identify the boundaries of your community and provide your proposed city council district lines.
