When developing a property, there are many factors to consider.
Zoning - Is my proposed use allowed? Are there any overlay zones or natural features on my property?
To determine the zoning and existence of any overlay zones or natural features on your property, please use BentonMaps or call the Community Development Department and ask to speak with the Planner On-Call.
Setbacks - Is my proposed project far enough away from property lines, roads and adjacent structures?
Once you know the zoning of your property and the type of structure (dwelling or accessory structure) you can navigate to the siting standards of the applicable chapter in the Benton County Development Code. Alternatively you may call the Community Development Department and ask to speak with the Planner On-Call.
Floodplain - Is my proposed project located in the regulated floodplain?
Whether or not your building site is in the regulated floodplain can have a major impact on your project. To find out more about the possible impacts of being in the regulated floodplain on your project please visit our floodplain webpage or call the Community Development Department and ask to speak with our Certified Floodplain Manager.
Water Supply - Does my property have access to potable water? Will the size of my proposed structure require sprinklers or water storage in case of a fire?
Potable Water: The use of water in Oregon is regulated by the Oregon Department of Water Resources. Sources of drinking water for a property are either provided by a spring, a well or a city water utility. If your property doesn't already have a water source and a city water main is not an option, contact your local water master for more information.
Fire Protection: To determine if the size of your proposed structure will require sprinklers or water storage in case of a fire, contact your local fire department. If there is no local fire department assigned to your property, then you will want to contact the Oregon Office of the State Fire Marshal at firstname.lastname@example.org or 503-373-1540.
Natural Resources - Does my property contain Fender's Blue Butterfly habitat, wetlands, or riparian areas?
To determine if there are any regulated natural features on your property, please use BentonMaps or call the Community Development Department and ask to speak with the Planner On-Call.
Natural Hazards - Are the soils on my property prone to landslides, high shrink-swell rates or high erosion?
To determine soils on your property, please use BentonMaps or call the Community Development Department and ask to speak with the Planner On-Call.
