ADMINISTRATIVE RULE SUMMARY
The purpose of the proposed rule is to designate interim flood hazard areas either: (a) on waterways which
do not have base flood elevations, floodway, or special flood hazard area (SFHA) boundaries established
through a flood insurance study; or (b) as a more restrictive standard in an existing SFHA. An interim flood
hazard area is an approximation of the floodplain.
The proposed administrative action to be taken is to modify Administrative Rule 109-020 Interim Flood
Hazard Areas. Administrative Rule 109-020 is being modified to reflect recent updates to Salem Revised
Code Chapter 601 (Floodplain Overlay Zones). This modification also adds base flood elevations to the
following SFHAs:
1) Northeast corner of the I-5 and Hwy 22 intersection.
2) South of Battle Creek Elementary between Waln and Powell Creeks.
3) Waln Creek upstream of Waln Drive SE.
4) East Side of I-5 Quarry Ponds.
5) Salem Municipal Airport.
6) McGilchrist Street SE west of 25th Avenue SE.
7) South side of Mill Creek between 23rd Street SE and 25th Street SE.
8) Mill Race between 14th Street SE and Church Street SE.
9) West Fork Pringle Creek upstream of Middle Fork Pringle Creek to Ewald Ave SE.
10) East Fork Pringle Creek South of Turner Road I-5 overpass.
11) Lake Labish Ditch near Chemawa Road.
12) Unnamed Tributary to Little Pudding River south of Hazelgreen Road NE.

INTERIM FLOOD HAZARD AREAS
Section 1: 109-020-010 Purpose Interim flood hazard areas are areas designated by the Director as an approximation of the
floodplain, depicting areas of flood hazard. These rules establish interim flood hazard areas for
waterways which do not have base flood water surface elevations and floodway and floodway
fringe boundaries established by the Federal Emergency Management Agency's (FEMA) Flood
Insurance Rate Map (FIRM). Interim flood hazard areas are established either: (a) on waterways
which do not have base flood elevations, floodway, or SFHA boundaries established through a
flood insurance study; or (b) as a more restrictive standard in an existing SFHA. An interim
flood hazard area is an approximation of the floodplain.

following SFHAs:
1) Northeast corner of the I-5 and Hwy 22 intersection.
2) South of Battle Creek Elementary between Waln and Powell Creeks.
3) Waln Creek upstream of Waln Drive SE.
