Oregon Department of Transportation's comment period for Portland Interstate 5 project ends April 1.

COURTESY ODOT - A draft planning document shows the area of Interstate 5 in Portland's Rose Quarter to be reworked by the Oregon Department of Transportation.In a scathing letter, high-ranking staff at Metro regional government slammed the state's planning documents for an Interstate 5 project in Portland as "inadequate" and "potentially misleading."

The seven-page letter sent to the Oregon Department of Transportation and the Federal Highway Administration claims that reworking the Rose Quarter segment of I-5 will indeed expand the highway — but the changes might do little to prevent serious crashes.

In both cases, ODOT had previously argued the opposite.

"(Claiming) that the project does not create new capacity or add substantial capacity to I-5... is not objectively true and is potentially misleading; auxiliary lanes clearly add capacity," reports the letter, which was first obtained by BikePortland.

The document, signed by Metro's director of planning, Elissa Gertler, lays out a laundry list of objections. But it isn't complete wish fulfillment for the cadre of activists hoping to torpedo the $450-million project, which was included in lawmakers' $5.3-billion transportation package passed in 2017.

For one, the letter doesn't explicitly call for the completion of an Environmental Impact Statement, a more stringent form of review than the Environmental Assessment published Feb. 15. The public comment period for the assessment ended 5 p.m. on April 1.

Here's what the letter does say:

• The Rose Quarter Improvement Project would slow down commutes for TriMet bus and Portland Streetcar riders due to "signal phasing changes" where transit lines approach I-5, Metro says.

• While ODOT already stated that its proposed highway lids across I-5 would be too weak to support buildings, Metro says planners should explore tunnel-style caps in order to harmonize with Portland's density goals and allow construction of two to 10-story structures over the interstate.

• ODOT says ending stop-and-go traffic in the narrow stretch of I-5 would decrease crashes by providing drivers with more space to merge and new shoulders to park disabled vehicles. Metro highlights that the primary factor for I-5 collisions is "driver behavior" such as inattentiveness or drunkenness. "It is not clear how the design solutions in the Build Alternative will address behavior," the letter notes.

• Metro says the proposal to create five one-way traffic lanes on a portion of Broadway is "incompatible" with the mixed-use environment it prefers, and may even encourage poor driving.

• The regional planning agency is clearly peeved that the state's technical reports were not shared with Metro for prior review, though Portland City Hall did get a peak.

The elected Metro council president, Lynn Peterson, sent her own diplomatically-worded two-page dispatch to ODOT as well, according to Bike Portland. The site's publisher, Jonathan Maus, speculates that decision let Metro employees "do the dirty work and keeps her hands clean for 2020 [transportation] bond push."

Activists are also concerned the new auxiliary lanes will cast shade over the Vera Katz Eastbank Esplanade, adding noise and pollution to the area.
