A master plan helps guide growth and development over the next 10 to 20 years. The plan serves as a policy guide for future land-use decisions, transportation, natural resources, community services, and coordination of infrastructure.

The current Warren County Master Plan was last amended in 2011. This update of the County Master Plan will be an opportunity to consider ways to accommodate future population and employment growth by coordinating land use policies, transportation and infrastructure improvements, municipal and county services, and preservation of natural resources.

Plan components are expected to include community vision and goals, existing conditions, growth analysis, future land use, economic development, housing, transportation and mobility, natural resources, utilities, and community facilities. While the plan will cover many topics, key aspects will be the future land use plan and transportation recommendations for areas of unincorporated Warren County.

An Advisory Committee will help guide the process. The Advisory Committee includes members of the Planning & Zoning Commission, communities, businesses, organizations, and county residents.

The planning team is led by the i5Group, along with SLU Community Planning Lab, and the Lochmueller Group. 

The public will have multiple opportunities to provide input as the plan is developed.

The jurisdiction of the plan will be the unincorporated areas of the County. However, cities in the County will also be involved in the planning process as it will be important to consider their future growth. In addition,  the plan will concentrate more closely on areas of the County with current or expected growth.

The planning process began in the Fall of 2025 and is expected to last 18-24 months.

Great question! Public involvement is an essential part of this process. There will be multiple in-person open houses for the public to attend. A countywide survey will take place in 2026. In addition, the planning team will be meeting with numerous community stakeholders and organizations.

Engagement activities such as the open houses and the online survey will be open to all residents in the County.
