DRAFT3h. Citywide Systems and Infrastructure


Issues related to Portland’s transportation, sewer and stormwater, water, and parks systems vary geographically:

Eastern Neighborhoods
Portland’s eastern neighborhoods face a variety of infrastructure challenges that may impede the area’s ability to serve existing residents and adequately accommodate additional infill development.

Western Neighborhoods
Much like the neighborhoods themselves, infrastructure in western neighborhoods often is shaped and constrained by the area’s hilly topography and streams.

Inner Neighborhoods and Central City
Infrastructure deficiencies in inner neighborhoods and central Portland are less severe than those in other areas and in general should not impede development. However, some of these deficiencies may affect the quality of life of area residents.

Portland’s Infrastructure

citywide areas





3,949 lane miles of roads;  157 bridg­es; 992 traffic signals, eight million square yards of sidewalks; 37,352 improved corners; 53,000 street lights.

10,200 acres of parkland; 180 developed parks; 47 habitat parks; 5 golf courses; 7 botanical gardens; arboretum; raceway; stadiums; 13 pools; 12 community centers; 177 miles of trails, 142 playgrounds, over 300 sports fields, 31 community gardens and over 100 tennis courts.



Bull Run watershed; Columbia South Shore wellfield; 220 million gallons finished storage; 75 mi. of conduits; 43 mi. of mains; 2,200 mi. of pipes; 1,500 culverts; dams; 33 wells; 180,000 service lines; 44,000 valves; 182,500 meters; 15,000 hydrants; 39 pump stations, 70 tanks.


Eastern Neighborhoods

eastern area



Poor street connectivity.


A number of unimproved and substandard streets.


Highest average vehicle miles traveled per person.


Five deficient bridges.


Issues with pedestrian, cyclist and automobile safety.


Many streets lack sidewalks.



The sanitary sewer system is in good condition.


Issues with stormwater runoff and infiltration in the Johnson Creek Watershed.


Potential compliance issues with underground injection controls (sumps).




An additional 58 acres of parks needed.


48% of park properties are undeveloped.


Poor pedestrian access to many  parks.


Poor recreation facility distribution.


Natural areas targeted for acquisition.


Few street trees and private trees being lost to development.




The City’s backup water source, the Columbia South Shore Well Field, is located primarily in east Portland, as is the Powell Valley well system.


Deficiencies limit fire flow in areas near Powell Butte


Inner Neighborhoods

inner neighborhoods area



Streets generally meet connectivity standards.


Lower vehicle miles traveled per person.


Good sidewalk coverage.


A number of high-crash intersections.


Sixteen bridges in poor condition.


Declining traffic signal condition.



Pipes with insufficient capacity and/or in poor condition are widely distributed, raising the risk of basement sewer back ups during storm events in some areas.


Significant combined sewer overflow (CSO) improvements to be completed in 2011.



Park development deficiencies in select areas.


Limited parkland access deficiencies.


Additional/improved recreation facilities needed.


Very limited walkable access to natural habitat.




Area has some of the oldest water infrastructure, resulting in high maintenance needs.


A new seismically hardened Willamette River transmission line crossing will be needed in the next 20 years.


Western Neighborhoods

western area



Few major arterials.


Streets do not meet connectivity standards.


Many unimproved or substandard streets.


Higher average vehicle miles traveled per person.


Most residential streets lack sidewalks.


Less than 1/3 of bikeways have been constructed.



Sanitary sewer concerns in Fanno Basin and related to Fanno Pump Station.


Efforts underway to inspect older sanitary sewers, which may have condition problems.


Significant stormwater management concerns.



6 undeveloped park properties.


Significant protected open spaces, but lacks sufficient developed parks and some sports fields.


High urban canopy rate, though it is being lost in some areas due to development.




Pump station & supply improvements are needed to improve fire flow in hilly areas.
