As the Fauntleroy Boulevard project gets closer to final design, many who are closely watching the process have asked for details of the newest traffic studies done by/for SDOT – since the project was on hold for a few years, and conditions changed in the meantime, new studies were ordered. The full report has just been linked to the project website, and we’ve uploaded it to Scribd so you can also see it, embedded, above (direct link to city-hosted PDF is here).
In short – SDOT says that the study’s results do NOT change its plan to eliminate the right-turn “pockets” at Avalon and Oregon. Right turns WILL still be allowed – but turns will have to be made from the outside through lane.
Meantime, if you don’t have time to read through the study report (31 pages) right now, here’s how the contractor summarizes its findings on page 28:
The proposed project will construct landscaped center medians, realigned intersections, improved street lighting, protected bike facilities and improved pedestrian facilities with defined sidewalks and new crossings of Fauntleroy Way SW.
DKS has completed a project traffic analysis of the existing, the year of opening, and the future 2044 project condition. The following summarizes the main findings of analysis:
The protected bike lanes are proposed to be one‐way on both sides of the corridor and therefore should have minimal impact on the signal operations as a bike signal phase will not be required.
The year of opening conditions accounts for an 8% growth which includes planned development within the next two years in the area. Signal timing changes at intersections along Fauntleroy Way SW and 35th Avenue SW are required to accommodate this growth. The signal timing adjustments, in conjunction with turn restrictions, provide acceptable LOS D or better operations in the year of opening conditions. Certain intersections experience better operations in future conditions due to optimized signal timing.
The proposed additional marked crosswalks across Fauntleroy Way SW at SW Avalon Way and at SW Oregon Street are not recommended as they would require an additional signal phase for an exclusive pedestrian crossing, reducing the efficiency of the intersection operations by introducing additional pedestrian and vehicle delay at the individual intersections and to the corridor.
The Fauntleroy Way SW Boulevard project is expected to allow for acceptable corridor operations through the year 2044. This is due in large part to PSRC’s new 2040 regional travel demand model which projects little vehicle traffic growth along Fauntleroy Way SW, but a 25‐33% growth in transit trips on the SW Alaska Street/35th Avenue SW transit corridor. Also, by 2040, both pedestrian and bicycle trips in this section of the City are expected to grow at approximately twice the rate of vehicle trips.
To ensure a conservative analysis, pedestrian volumes were assumed to double at the intersection of SW Alaska Street/Fauntleroy Way SW Boulevard, while bicycle volumes were assumed to double along the corridor for the year of 2017. Through 2044, pedestrian volumes were assumed to double at every intersection and bicycle volumes were assumed to triple along the corridor.
Meantime, SDOT continues taking comments through the end of this month on whether to break the median at 37th SW – scroll to the middle of the project page to see how to send your thoughts. The city expects to finalize the design this summer and start construction earlier this year.
