Portland-Milwaukie Light Rail Project - FEIS - Volume 1 - TriMet

3.10.3.7 Fixed Noise Sources and Ancillary Facilities
As required by the FTA, fixed sources, such as park-and-rides, maintenance bases, power
substations, and other fixed ancillary and support facilities must meet any local noise ordinances
or regulations. For these sites, actual measured noise levels, noise levels from similar projects,
and standard acoustical formulas and calculations are used to predict future operational noise
levels. The predicted levels are then compared to the applicable regulations. Where noise levels
are predicted to meet or exceed the FTA criteria, noise impacts are identified and mitigation
measures will be investigated. Mitigation that is deemed feasible and reasonable can be
recommended for inclusion with the project.
3.10.4 Affected Environment
The project corridor was examined to identify noise-sensitive and vibration-sensitive locations
and to select locations for supplemental noise monitoring. Noise and vibration measurement
locations used in the analysis are shown in Figure 3.10-4.
Land use along the Portland-Milwaukie Light Rail Project Corridor includes single-family and
multifamily residential, office and commercial, industrial, institutional, educational, and
recreational. Residential land use on the west side of the Willamette River includes the Village at
Lovejoy Fountain and the American Plaza Towers Condominiums, both on SW Lincoln Street,
and the RiverPlace Square Apartments and Marriott Residence Inn, both in the RiverPlace
community. Other noise- and vibration-sensitive uses include the Mission Control production
studio on SW 1 st Avenue and the International School on SW Sherman Street. There are also
commercial, industrial, and undeveloped land uses near the proposed Willamette River crossing.
Sensitive land uses on the east side of the Willamette River include OMSI, the Portland Opera
Offices, and the Willamette River Greenway. Land use along the shared corridor between SE 7 th
Avenue and SE 12 th Avenue is predominantly commercial and industrial; however, there are
residential land uses on SE Caruthers Street, SE 9 th Avenue, and along SE 12 th Avenue. There is
also a church located near the at-grade crossing on SE 12 th Avenue north of SE Clinton Street.
South of SE Powell Boulevard, land use directly adjacent to the alignment is primarily
commercial and industrial, and includes Portland General Electric and TriMet’s bus maintenance
facility. There are also two residences on SE 17 th Avenue. Land use along SE 16 th Avenue,
directly west of the project corridor, is virtually all residential between SE Powell Boulevard and
SE Holgate Boulevard. Project corridor land use south of SE Holgate Boulevard is primarily
commercial and industrial to SE McLoughlin Boulevard. There are four residences along SE 16 th
Avenue, just north of SE McLoughlin Boulevard.
Land use along SE McLoughlin Boulevard includes commercial and industrial uses, a golf
course and the UPRR train tracks to the east, and residences on the west side of SE McLoughlin
Boulevard. Westmoreland Park is located on the west side of SE McLoughlin Boulevard, south
of SE Bybee Boulevard.
South of SE Tacoma Street, east of the alignment is the Ardenwald residential community, and
to the west, the land use is mainly commercial and light industrial. South of Highway 224, land
uses include single-family and multifamily residential, the Portland Waldorf School, St. John the
Baptist Catholic School, Milwaukie High School, the Ledding Library, Dogwood Park, the
