DRAFT3h. Citywide Systems and Infrastructure

Neighborhoods

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.

Eastern Neighborhoods

eastern area

Transportation

 

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.

Environmental

 

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).

 

Parks

 

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.

 

Water

 

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

 

Transportation


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.

 

Environmental


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.

 

Parks


Park development deficiencies in select areas.

 

Limited parkland access deficiencies.

 

Additional/improved recreation facilities needed.

 

Very limited walkable access to natural habitat.

 

Water

 

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

 

Transportation


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.

 

Environmental


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.

 

Parks


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.

 

Water

 

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