Engineering Utility Asbuilt Drawings
Engineering utility system record drawings (asbuilts) are available using either of the three following options:
1. If you know the asbuilt drawing name, use the listing at the bottom of this webpage. Maps are listed by subdivision and project names.
2. Use West Linn Maps, the City's Interactive Mapping application, click here: https://westlinnoregon.gov/maps/west-linn-maps
Asbuilts are available for "City Owned" utilities in the public right-of-way only and are not typically provided for privately maintained systems. Also record drawings for ‘’critical facilities” are not included on this web site. Critical facilities include water reservoirs, transmission lines, pump stations, treatment plants, schools, etc. If you need access to critical facilities asbuilts, please contact the West Linn GIS Coordinator using the “Contact Us” link provided on this webpage.
Please read the GIS disclaimer before accessing these files and be aware that field surveys are recommended to verify accuracy of the system represented on these maps.
DISCLAIMER:
OVERVIEW: The information used in this application was derived from digital databases from West Linn’s GIS. Although we strive to provide the best data we can, we sometimes use data developed by jurisdictions outside West Linn. Therefore, West Linn cannot accept any responsibility for any errors, omissions, or positional accuracy, and therefore, there are no warranties which accompany this product. Although information from Land Surveys may have been used in the creation of this product, in no way does this product represent or constitute a Land Survey.

GENERAL GIS MAP DISCLAIMER: This product is for informational purposes and may not have been prepared for, or be suitable for legal, engineering, or surveying purposes. Users of this information should review or consult the primary data and information sources to ascertain the usability of the information.
QUALITY OF SCANNED MAPS
Please note that older asbuilt drawings (1990's and older) may have legibility problems due to poor quality originals (hardcopy paper and mylar maps). We have scanned these older asbuilts using modern, high-resolution wide-format scanning equipment and scanned images provided by the City on this website match the original as close as possible
Interactive Mapping
You can also access utility asbuilts using our interactive map application called West Linn Maps. Use the link above to access West Linn Maps.
If you have difficulty finding the asbuilt for a specific location, please use the contact us link on this webpage, addressing your question to the GIS Coordinator. Please provide the address and taxlot or parcel number in your request.
