County Maps
The county's online maps have layers you can turn on to see which zones and regulated environmental areas (if any) are on a property. Once you know which critical areas are mapped on a property, you can look up the specific development rules that apply to the property. In most cases, these layers are also listed on a property's Parcel Data Sheet (see Step 1 on Look up Your Property). Online county maps are made by the County's GeoData Department.

How to use maps to see which zoning & regulated environments are on a property

Step 1  Have map instructions handy before you begin
  • Maps open with instruction panel visible, but the panel closes as you click other buttons. 
  • Quick Start Instructions, show step-by-step directions. 
  • Detailed Map User Instructions (PDF), have more complete instructions. 
Step 2  Open the online map & search for a property
  • Permitting Map - Open this map to see if wetlands, Mazama pocket gopher areas, shorelines or other regulated land and waters are mapped on a property. 
  • Show Me Everything Map - Open this map to see all of the above, plus everything the county has mapped for a property, on a single map. Slow loading.
  • Search for a property using an address or parcel number. To get a property's parcel number, enter its address in parcel search.
Step 3  Find a property's jurisdiction, zoning & critical areas (regulated sensitive environments)  
  • Click on Maps & Layers at top left, then select Show Layers List. 
  • Scroll down to Planning & Land Use, and check Permitting jurisdiction, UGAs (part of the zoning info) and Zoning to turn on those layers for the selected property.
  • Or follow zoning lookup instructions to check the zoning.
  • Follow critical areas lookup instructions to check for regulated environments, lands, waters, etc.
  • Tip: Writing down what you find can make filling out permit forms, or talking to staff or other experts about your project/property easier.
Step 4  Look up the development rules associated with the zones & regulated areas you found

What to expect when using online county maps

  • Online maps take a little trial & error to figure out. Please allow yourself some time, and read the instructions. 
  • You can use a property address or parcel number to search for a property. Using a parcel number can bring up the right property faster. 
  • Maps don't meet legal, engineering or survey standards because land and water-flow change over time. 
  • Sometimes property owners hire their own experts to confirm actual conditions on a property, and exact location of any critical areas (like wetlands) or other regulated environments (like Mazama pocket gopher habitat, shorelines, etc.). 
  • Use county maps to start your research, but you may want to consult with your own experts before making decisions.

Online map features: cool things you can do with the map

  • Base maps - Maps open on a standard street view, but you can switch the base map to an aerial to see buildings, roads, trees and other features clearly. Learn how.
  • Layers - You can turn layers on and off to see what's on a property. Once in a map, click Maps & Layers at the top left, or click Layers at the bottom left. At about the 3:50 mark in the GeoData Training Video.
  • Drawing - Add a rectangle or square to show where your bulding project will be. Save drawings to your computer, or send a drawing to someone else.
  • Not so cool features - you can't save your work and come back to it, but if you draw a shape on a map, you can save that to your computer or thumb drive.

Visit the county's map department online at www.geodata.org

The County's map-making department is called GeoData. They make great maps, but because land and water are ever-changing, and because new data is added frequently, county maps don't meet legal, engineering or survey standards. Hire your own experts before making decisions.
