Pendleton Multi-way Boulevard and Green Infrastructure Improvements
Joint Base Lewis-McChord, WA
Suppliers: Mutual Materials Company
Owner: US Army Corps of Engineers, Seattle District
This 100,000 square foot installation at a major military base in the Pacific Northwest used permeable interlocking concrete pavers as part of a sustainable design and green infrastructure project. 100% of all runoff is treated and infiltrated within the right-of-way through the permeable pavement system and two miles of rain gardens on both sides of the 160 ft. wide Pendleton Boulevard Multi-way. PICP's are used primarily in an access lane that separates main boulevard traffic from pedestrian and parking areas. These "flex-space" access lanes can be closed to motorized traffic for community events without interrupting main traffic flow. Two colors of pavers were used to further separate parking areas from traffic lanes without painted street lines. The abundant plaza spaces in the overall project contribute to a linear parklike atmosphere. Businesses report increased sales along the boulevard, attesting to the exposure and accessibility of the area. The result of this forward-thinking infrastructure project is one that accommodates heavy military traffic, civilian vehicles, cyclists and pedestrians in a very comfortable corridor. Cascade Design Collaborative developed the sustainable design and details for this project. Mutual Materials was a great help to their efforts in developing the permeable pavement cross section. The prime design firm, Berger ABAM, provided overall engineering and utility design.
