Portland first doubled the size of its bus network, all powered by biofuel, before being the first American city to adopt a new streetcar system in Local companies and car parks mainly financed the cost of the project, which amounted to 70 million euros.
The city offers a Free Rail Zone formerly called Fareless Square encompassing most of downtown Portland within which bus and streetcar travel is free and automobile access limited. In addition to cash — which plays a significant role in motivating people — they also supply secure bike parking, showers, access to tools and free route maps.
Public investments in mobility and infrastructure are also supplemented by non-governmental organisations like the Community Citing Center, which provides free bicycles for low-income citizens as well as training in cycle repair and road safety. Portland, innovative also in terms of sustainable urban drainage systems, has developed a world-renowned stormwater management programme, operational since the early s, to avoid sewer flooding, reduce pollutants in rainwater, and protect and enhance groundwater quality.
The Sustainable Stormwater Management Plan intends to minimise impervious surfaces by implementing sustainable design into new and remodelled infrastructures and landscapes, including communication, education, community greening and making the city more attractive. Strategies range from a simple barrel at the bottom of a downspout in private plots to innovative rainwater harvesting systems such as green roofs, rooftop gardens, buffers, bioswales, permeable paving, and separate stormwater systems with multiple tanks, pumps and controls.
The water is filtered through a sand trap and then treated with ultraviolet light before being pumped back into the Epler building to be reused for public restroom flushing and irrigation of the surrounding landscape. Its water coming from the rooftop is stored in a 1,gallon 3.

Over one-third of Portland's 2, miles of sewer pipes are more than 80 years old. Green infrastructure protects the aging sewer system and makes it operate more efficiently by keeping stormwater out of sewers. Green infrastructure brings nature into the city, which can improve both mental and physical health, increase property value, conserve energy, enhance wildlife habitat and save money on more costly pipe infrastructure.
