CURRENT DATE:  11/21/12

The City of Lake Oswego Planning Commission will hold a public hearing in the City Council Chamber located in Lake Oswego City Hall at 380 A Avenue on Monday, December 10, 2012, 6:30 p.m.  The Commission will consider LU 12-0047 (Ordinance 2603), a request from the City of Lake Oswego.

The City of Lake Oswego is considering adoption of changes to the City’s Flood Management Area maps and text. These changes reflect recent map revisions made to the Federal Flood Insurance Rate Map that depict lower base flood elevations around Oswego Lake.

Explanation of Proposal:
Proposed Ordinance No. 2603 (LU 12-0047), has been drafted to comply with Federal Emergency Management Agency (FEMA) regulations for Flood Insurance.
•    The Flood Insurance Rate Map, prepared by FEMA, is used to determine the location of the floodplain and what rates are charged for flood insurance.  The City of Lake Oswego’s Flood Management Area Map (Figures 50.05.011-A through D in the Lake Oswego Community Development Code) is based on the FEMA Flood Insurance Rate Map and the area of inundation during the flood of 1996.   The City’s Flood Management Area Map is used to determine where City floodplain regulations apply.
•    The City of Lake Oswego has received a Letter of Map Revision from FEMA, dated April 9, 2012, effective August 24, 2012. The FEMA letter revises the Flood Insurance Study Report and Flood Insurance Rate Map to reflect lower floodplain levels that result from the recent improvements to the Oswego Lake Dam spillway.
•    The map revisions decrease the estimated Base Flood Elevation (commonly referred to as the 100 year floodplain) for Oswego Lake by approximately four feet. Revisions also note changes for portions of Oswego Creek below the Oswego Lake Dam; FEMA does not have an established Base Flood Elevation for this area.
•    Map amendments reflect the revisions above. Text amendments update references to the amended maps.

Location of Properties:  Properties on Oswego Lake, Blue Heron Canal, Lakewood Bay, and West Bay.  To view a map of the proposed revisions to the flood management area, visit and click on the Flood Management Area Map under the heading Notices/Announcements.

A copy of the proposed amendments is on file in the Planning & Building Services Department at City Hall.  Since the time allowed for public testimony is limited, you are urged to review the record and be thoroughly familiar with it if you plan to testify.

NOTE:  Failure to raise an issue in a hearing, in person or by letter accompanied by statements or evidence sufficient to afford the Planning Commission an opportunity to respond to the issue precludes appeal to the City Council and the Oregon Land Use Board of Appeals (LUBA) based on that issue.

Staff coordinator is Denny Egner, Asst. Planning Director, (503) 635-0270.  For additional information, visit the City’s website at:
