Projects

The City of Lake Oswego needed to update its Total Maximum Daily Load (TMDL) Implementation Plan to continue protection of its water resources and to meet state water quality standards.

Parametrix (previously as Parisi Transportation Consultants) has partnered with the City of Larkspur on several multimodal transportation improvements projects.

Parametrix provided bathymetric survey for demolition of a wharf in a remote area. High resolution upland and bathymetry surveys with full overlap were completed on short notice.

Parametrix is providing survey services for Port of Everett facilities including multibeam, single beam, 3D scanning, and topographic data collection, as well as data processing, quality control, and drafting of comprehensive marina berthing diagram plan sets

Fish passage was being blocked through three culverts along Ostrich Creek due to high velocity conditions and the presence of large outfall drops.

Lincoln Street (US 101) is a key transportation route through Port Angeles and one of the City’s most active arterials. This project provided several multimodal pedestrian and bike improvements to improve safety through the downtown core.

The SR 410/Traffic Avenue Interchange is significant to the growing South Sound region; it is a freight route, provides access to a regional commuter rail station, access to the free for emergency services, and acts as the entrance to downtown Sumner.

The 2.3-mile Noll Road Corridor Improvements project connects SR305 to NE Lincoln Road. The improvements included 0.6 miles of new alignment and widening of 1.7 miles of existing roadway.

The I-84 Meridian Road Interchange project replaced an existing diamond interchange with a new Single-Point Urban Interchange (SPUI) and reconstructed over 4 miles of interstate to provide additional capacity, improve safety, and extend the design life of I-84.

The I-84 Corridor improvements were intended to improve mobility, increase safety, and benefit the regional economy.
