County Mission
Q: What are Land Use Assumptions?
A: The DuPage County Land Use Assumptions document is not a land use plan, nor is it a prescriptive document that mandates land uses, zoning or regulations of any kind.
The document is an assessment of the kind of land use that currently occupies parcels inside the County’s planning territory and how property may develop or re-develop over time.

Land Use Assumptions Objectives
Q: What are the objectives of the Land Use Assumptions?
PROPOSED FY2018 BUDGET COMPONENTS
A: Accurate Assessment of Current Conditions in DuPage and surrounding Counties
Develop a More Detailed, Rigorous and Locally Responsible Land Use Forecast Model
Produce a high quality trip production and attraction basis for Future (2025 and 2040) Trip Generation and Distribution Models
In these land use assumptions, DuPage County strives to incorporate unique and defensible future development components building upon long-standing historical development tracking at the County. The County uses as many local and regional resources as possible to assess and predict land use outcomes in the short and long term.

Land Use Assumptions
Q: Is DuPage County still experiencing the same kind of growth as 10 – 20 years ago?
PROPOSED FY2018 BUDGET COMPONENTS
A: No.
Housing development is slowing and recent trends suggest that more multifamily and senior housing is being built now than in past decades.
Commercial development has also slowed in the office and retail sectors and the past 5-10 years has seen more vacant space absorption than new starts.
Warehousing has been the most active sector with more than 7 Million square feet built in DuPage since 2010.
