STUDY AREA #4 ALOHA-COOPER MOUNTAIN

The corridor is predominantly residential, with limited commercial areas or major employers.

About 66% of households are within ½ mile of regional destinations such as schools, shopping centers and major employers – well below the county urban area average.

Employment and households are expected to increase by 45-50% by 2035

Summary

Overview

DRAFT September 17, 2013

Study Area #4 CONNECTIVITY

Findings Street network and intersection density are slightly below county urban area average.

The study area has a relatively abundance of dead-ends and cul-de-sacs. These features can be attributed to mid-century development and limited crossings at streams.

Study Area #4 ACTIVE TRANSPORTATION

Findings Sidewalk coverage is similar to the county urban area average, although many gaps remain with no

sidewalk facilities on either side of the roadway.

Bicycle facility coverage is significantly lower than the county urban area average.. The average distance between crossings is significantly higher than the county average. 185th

Avenue, Millikan Way and TV Highway have the longest average distances between crossings. The Portland & Western Railroad is also a major barrier with few convenient or safe crossings for people walking and accessing transit.

Trail coverage by population is below the county urban area average.

Study Area #4 MODE SHARE

Findings

Forecasted 2035 mode shares are relatively consistent with 2010.

No significant increase is identified for combined walk, bike, and transit mode shares. Non-SOV mode share is projected to fall within regional target range.

Study Area #4 TRANSIT

Findings Transit access for households and employment are similar to the county urban area average.

Transit access to low income and minority household areas is better than county urban area average. Many of these households are served by the frequent service #57 bus, along TV Highway.

Transit service is currently limited in the Cooper Mountain and South Hillsboro areas, where major development is beginning.



Study Area #4 MOTOR VEHICLE DEMAND & TRAVEL TIME

Findings Total motor vehicle travel miles traveled in the study area are projected to increase 43% in 2035 relative to

2010. However, VMT per capita is expected to decrease by 5%. Significant increases in roadway travel times anticipated for 2035 PM peak on:

o Roy Rogers Road/175th Avenue, between Beef Bend Road and Rigert Road (24% NB, 22% SB) o Murray Boulevard (SB), TV Highway to Scholls Ferry Road (22% increase) o 185th Avenue, between Baseline Road and Rigert Road (20% NB, 28% SB) o 209th Avenue (SB), TV Highway to Farmington Road (39% increase)

Overview

Study Area #4 CONGESTION

Findings Significant increases in roadway congestion and delay are anticipated in 2035 relative to 2010. Mobility standard deficiencies are identified during 2035 PM peak for many roadways in the study area

including segments of Roy Rogers Road, 160th Avenue, 170th Avenue, 175th Avenue, 185th Avenue, 190th Avenue, 209th Avenue, Murray Road, Grabhorn Road, Kemmer Road, TV Highway, and Farmington Road.
