Kenton Denver Avenue

Portland’s first green main street, the Denver Avenue Green Street extends along the four-block historic Kenton business district in north Portland. The initial phase of the streetscape design developed an overall concept for the street section, including the widening of sidewalks, addition of bike lanes, and the restructuring of existing parking, drive lanes and medians. The design developed through input from a Citizen Advisory Committee, a Technical Advisory Committee, and with extensive public involvement at open house meetings. GreenWorks, as part of a multi-disciplinary team, prepared an overall street layout for the corridor that defined paving patterns, materials, street trees, site furniture, ornamental light fixtures, and the design of gateways at either end of the corridor. An important component was the integration of green street stormwater solutions within the right-of-way. This project was completed on time and on budget.

Our initial design work moved successfully into a constructed streetscape project in 2010 with GreenWorks providing construction documentation led by the Portland Bureau of Transportation. As a main street and ODOT-designated freight route, we successfully integrated sustainable design with main street design to create a vibrant streetscape. Long suffering from a high storefront vacancy rate, the Kenton downtown now has experienced a boom in new businesses and its local economy.


Tigard River Terrace

GreenWorks assisted the City of Tigard to develop a vision for the new main street in the River Terrace community. The new center spine of the community, which is parallel to and east of Roy Rogers Road, is envisioned as a boulevard that seamlessly integrates the River Terrace Trail into its design, provides safe and comfortable multi-modal travel options, and includes high-quality pedestrian-scale design treatments that define it as the neighborhood’s signature street. In order to successfully balance mobility with safety and comfort, it is important to control speeds along this street through a variety of design approaches that facilitate through travel but discourage cut-through traffic. Residential parking and access needs were carefully considered during the design process, including, at a minimum, an evaluation of how any proposed parking and access would impact trail users, vehicular travel speeds and volumes, and subdivision design (e.g. block length and orientation of dwelling units). The overall design of the street will serve to enhance the neighborhood and the adjacent residences without being a barrier to those who will live on either side of it in the future.


St. Helens US 30 Corridor Plan

This large-scale planning project involves planning for both a state highway and main street urban streetscape. The goal of the Highway 30 project is to provide safe, convenient access to local businesses along the highway, while balancing that with state goals for traffic mobility. GreenWorks is providing design and planning overview for this project.

Sandpoint Downtown Streetscape

GreenWorks developed green street schematic design concepts for the City of Sandpoint, Idaho, which will serve as a green street pilot project for the City of Sandpoint. Concepts for these existing streets looked at different options for how to retrofit green infrastructure to work with different existing conditions and how the design would fit with the character of the neighborhoods. Some of many issues considered in the designs were preserving existing mature trees, ease of snow plowing operation, on-street parking, vegetated stormwater facility types and pedestrian circulation.



Oregon City Warner Milne Rain Garden

As part of the realignment of Warner-Milne Road at the Molalla Avenue intersection, the City of Oregon City hired a team with GreenWorks to design a rain garden in a vacated portion of the right-of-way that will treat stormwater runoff from the adjacent heavily-travelled roadways. A series of large serpentine Corten steel fins meander through the site, articulating the stormwater channel and creating a striking contrast to the lush rain garden plantings. The first of its kind in Oregon, this rain garden incorporates prominent sculptural elements that highlight the City’s committment to sustainability.


Metro SW Corridor

GreenWorks assisted Metro and its regional partners in developing a comprehensive land use and transportation planning study to identify and prioritize public investments in the corridor between downtown Portland and Sherwood. The Southwest Corridor Plan builds on 25 years of the region’s experience in light rail and high capacity transit planning and has shown that major public investments in transit bring the highest value and return on investment when done in coordination with local visions for livable communities. 
Parks and natural resources are a key component for livable communities.  GreenWorks facilitated stakeholders interviews with the project partners, existing conditions analysis and created a comprehensive inventory of parks, trails, natural resource and green infrastructure projects across the region. GreenWorks assisted in screening, evaluating, and integrating this regional comprehensive list of projects into the transit alternatives for the SW Corridor ultimately for selection of the preferred transit alternative. The plan integrates natural areas, habitat corridors and trail connections to provide a more holistic plan that elevates the value of the area’s natural resources.


Empire Boulevard

The City of Coos Bay received federal funding to install bike lanes, landscape strips, and sidewalks to Empire Boulevard between Newmark Avenue and Wisconsin Avenue to provide alternative transportation opportunities along this heavily traveled corridor.

Improvements include widening the existing two-lane road to make room for on-street parking and bike lanes, installing curb, gutter, landscape strips with street trees, and sidewalk on both sides of the road. Stormwater / water quality facilities are constructed to manage stormwater on-site, converting Empire Boulevard into a ‘green street’. Other project elements include interpretive overlooks with site furniture, illumination, signing, striping, and numerous driveway connections.
