Campbell Park Master Plan

Working on a tight schedule with a lean budget, Mackenzie created the Campbell Park Master plan for the City of St. Helens. The master plan includes reconfigured tennis and basketball courts, and a nature trail through a stormwater meadow. Mackenzie’s ability to listen carefully, then deliver the plan with a degree of intentional independence, took a burden off the City staff, and allowed them to focus on other priorities. Ultimately, the master plan greatly contributed to the City successfully obtaining grant money for improving the park.Learn more

Clackamette Park Master Plan

Clackamette Park, one of Oregon City’s largest parks, is located at the confluence of the Willamette and Clackamas Rivers. These two iconic rivers provide both the park’s allure and serious challenges to its year-round use. Mackenzie’s master plan addresses the park’s resiliency while improving pedestrian and bike connectivity. Much of the park becomes unusable in the wet period of the year because of river swells and storms. The park includes an RV park which is closed every winter, resulting in a loss of revenue to the city. The design team gathered input from park maintenance staff, who...Learn more

Millard Park Master Plan

Building on a history of successful collaboration, the City of St. Helens reached out to Mackenzie for the master planning of a park on 20 acres of vacant land. Our integrated team worked quickly and efficiently with a lean budget to create a vision of a multi-generational park with amenities for everyone in the community, from exercise enthusiasts to bird watchers. As the city determined the best use for the site, the master plan was used as a tool to communicate the potential value of the property as park. The plan outlined the park boundary and defined its relationship to adjacent,...Learn more

Thatcher Community Park

Thatcher Community Park was developed on a 25.5-acre site situated in the City of Forest Grove’s urban growth boundary but still viewed as a rural area. This perception rendered it critical to gain a true understanding of the history, current issues and future potential of the area to build public consensus for the park’s planned amenities. The park was constructed in two phases. The challenges this added layer of planning introduced were addressed through a thorough analysis of construction options and budget reviews. Coordination with several public agencies was necessary to ensure all...Learn more

Portland Public Schools Athletic Facilities

Mackenzie is a committed partner to the Ten Great Fields effort to improve safety and playability and bring Portland Public Schools’ field and track facilities up to NFHS standards. The firm’s engineers, architects, and planners have coordinated with the district and booster organizations on improvements at seven PPS high schools, including Lincoln, Cleveland, Wilson, Franklin, Madison, Roosevelt, and Jefferson. For Lincoln, Mackenzie designed a phased project to convert a natural turf field to synthetic turf and upgrade associated facilities. Phase I, completed in 2002, included a new storm...Learn more

Mt. Scott Fire Station

This 12,000 SF, two-story facility houses two coed battalion crews. The simple and clear floor plan creates efficient divisions to form three distinct zones: the apparatus bay, living quarters, and public areas. These three zones have been used to establish three different volumes, breaking the building into smaller masses, a more interesting shape, and a human scale. The apparatus area includes two drive-through bays and a half bay for a future battalion chief vehicle. Semi-private bunkrooms with locker facilities, a day room with balcony, and an exercise room provide accommodations for 10...Learn more


Mackenzie provided site development services for Genentech’s 296,000 SF Hillsboro Fill and Finish (HFF) facility. Initially, Mackenzie prepared alternative conceptual site plans for the approximately 12-acre Phase 1 project within Genentech’s 75-acre parcel. Mackenzie, in collaboration with Flad and Associates , prepared final conceptual site plans and engineering plans and managed Development Review approval from the city. Mackenzie then provided civil engineering and landscape architecture design and construction documents for the project and comprehensive A/E construction administration...Learn more
