REQUEST LWI MAPS AS GIS SHAPEFILES
The more recent LWI maps are submitted with GIS shapefiles of the wetland layers.  Some of the older LWIs predate this technology. See the View Local Wetland Inventory maps and reports list to check availability.
 
To request LWI GIS layer shapefiles contact (Randy Sounhein at 503-986-5270)   
We will post the requested files to the FTP site and provide download instructions. GIS data consists of multiple files.  Since these are large files they will be compressed (zipped) for easy download and organization.
 
For users with an operating system older than Windows 7, you will need to use a Zip software program in order to unzip these files. If you do not have Windows 7, or a Zip program on your system, you may click here to download a common Zip application.

ORDER AN LWI MAP OR COMPLETE SET OF MAPS 
 
Copies of an entire LWI map set can be requested. LWI maps range in size from 11"x17" to 36"x48" and usually consist of several maps; however, some LWIs may have as many as 50 maps. The cost varies depending on map size and the number of maps.  The Department may charge an extra fee or may need to use an outside vendor for reproduction.  Estimated cost ranges from $2.00 to $5.00 per map sheet for black & white reproduction and $4.00 for shipping for the first map and $0.25 for each additional map. In addition, a $21.00/hour labor will be charged, pro-rated to the quarter hour.  Please contact the Department (Heather Howard or Andrea Downing at 503-986-5235) for an estimated cost on the LWI you are requesting.  Pre-payment is required.
