DATE OF HEARING: January 11, 2010
TO: Springfield Planning Commission PLANNING COMMISSION
TRANSMITTAL
FROM: Mark Metzger, Planner III MEMORANDUM
SUBJECT: South Bank Viaduct: Willamette Greenway Development Permit
and Site Plan Review
ISSUE: The City of Springfield and the Oregon Department of Transportation (ODOT) are
collaborating on the construction of a bicycle/pedestrian viaduct (South Bank Viaduct) which will
allow the existing South Bank Path to continue along the riverfront through Glenwood. At issue
is whether the proposed structure complies with Springfield planning policies and site plan
design standards.
DISCUSSION: The Planning Commission conducted a joint hearing with the Lane County
Hearings Official on December 7, 2010. A large portion of the viaduct lies outside of the city
limits, but within the Springfield UGB, triggering the Hearings Official’s participation.
There was an insufficient number of Commissioners present for a quorum. The hearing
conducted and was closed. The record left open through December 10 to allow staff to submit
revised conditions of approval in response to a request from the Hearings Official and the
Commissioners. Attachment 1 contains the proposed amended conditions of approval from
staff.
The Hearings Official received the staff amended conditions of approval on December 13th and
issued his decision on December 15, 2010. He approved of the project with conditions, based
on the revised staff conditions found in Attachment 1. His decision is attached as Attachment 2.
The Hearing Official’s conditions of approval are found on page 5 of his decision.
RECOMMENDATION: Staff recommends that the Planning Commission approve the
Willamette Greenway Development Overlay District permit and Site Plan (Tentative) as modified
by the conditions of approval issued by the Lane County Hearings Official. While the
Commission is not required to follow the decision of the Hearings Official, his decision and
conditions of approval are substantively consistent with the recommendations of staff.
ACTION REQUESTED: Please review the staff report and attachments submitted with your
packet for the December 7th hearing. Members absent from the December 7th hearing should
listen to the recording of the hearing provided by the Planning Commission Secretary. The
Planning Commission is requested to consider the proposed South Bank Viaduct and approve
it, approve it with conditions, or to deny the applications.
