These Details are intended for
use by design professionals for the design and construction
of public improvements required to provide service to private
development but which are owned and maintained by the City
of Lake Oswego. They should also be used for the design
and construction of privately owned and maintained facilities
to be located in City owned rights-of-way and/or to be connected
to City owned facilities.
It is expected
that changes in technology, materials of construction, and
contractors' means and methods will require periodic revision
of these Details. However, modification of these Details
without express approval by the City Engineer is prohibited.
Your assistance in reporting any errors and providing suggestions
for additions, deletions or revisions to maintain these
Details is welcomed and appreciated. Inquiries regarding
current or imminent revisions, suggestions, and reports
of errors or omissions should be directed to the City Engineer.
We try to update
these details on a regular basis, however, we do not guarantee
that the most recent version will be published on this site.
