The city of Portland hearings officer issued his recommendation for the Colwood Golf Course rezoning proposal (6.5 MB PDF) on August 22, including the traffic mitigation plan that would require the addition of a third lane to southbound onramp from Killingsworth Blvd to I-205.

Final approval of the proposal (3.5 MB PDF) — which would preserve about 90 acres of the Colwood Golf Course as open space by turning about 48 acres into industrial zoning — goes to a public hearing at the Portland City Council on Wednesday, September 25 at 2 PM.

Neighborhood residents are encouraged to testify at the hearing to express their views about the onramp widening. Testimony can also be submit in writing in advance. See these helpful tips for testifying (PDF) on land use cases.

The 48 acres to be rezone is located entirely north of Cornfoot Road and Alderwood Road. Widening the onramp here in Sumner — 1.5 miles from the site being rezoned — is the traffic mitigation solution recommended by Portland city staff and approved in full by the hearings officer. Here is the recommendation:

Prior to issuance of Building Permit and/or Site Development Permits for new development on Tax Lot 100 (48.36 acres), off-site transportation improvements must be addressed, through coordination and construction under separate Public Works Permits issued by PBOT and ODOT, with the following improvements:

  • Add a third queuing lane for the southbound on-ramp to result in three 12-foot wide lanes;
  • Widen to the outside of the existing lane to accommodate the additional lane;
  • Replace the existing ramp meter to accommodate the additional lane;
  • Provide new illumination;
  • Accommodate stormwater from the new impervious area in roadside swales; and
  • Provide any necessary related improvements to NE Killingsworth at the intersection with the southbound I 205 ramp.

Normally a land use issue in a nearby neighborhood is of limited interest. The problem in this case is that the land use proposal is in one neighborhood, while the entire proposed traffic mitigation solution is located in another neighborhood. In such a case, the city is not required to notify the second neighborhood, as Sumner Association of Neighbors (SAN) was not notified about this part of the otherwise worthy Colwood proposal.

On June 26, I (Scott, SAN chair) filed comments about the onramp portion of the land use proposal (350K PDF). On July 23, the rezone applicant, the nonprofit group Trust for Public Lands, filed a response (2 MB).

Thanks to the applicant in correcting one point I made in my comments. The onramp is in the list of regional transportation plan projects (XLS), although it is not in the RTP itself (40 MB PDF).
