Though SDOT reaffirmed two months ago that its planned speed-limit cuts for three more West Seattle arterials would happen before the end of 2015 as planned, they didn’t happen. They’re still on the way, says SDOT’s Jim Curtin, but one of them – Delridge Way north of Orchard – will come with something extra: Fog lines. This news came in another round of correspondence with the concerned citizen whose questions sparked our November followup, “A Dad On Dangerous Delridge.” Curtin’s first reply to ADODD this week:
In an effort to achieve the lower speeds we seek on Delridge, we will be adding a fog line (aka edge line) to narrow the existing travel lanes on the street. The National Association of City Transportation Officials (NACTO) has a good website dedicated to lane widths here. Some sections of Delridge already have an edge line but most areas do not. Several locations, including the area just south of the Boren Building (home to two schools), have wide swaths of roadway with little to no organization or structure. The edge line will change that and help us reduce vehicle speeds on the corridor. This work is weather-dependent so we’ll need some dry weather before we can install the new pavement markings. We are hoping to make this change in the first quarter of 2016 during a dry stretch. A public communications effort will accompany these changes to help raise awareness of the speed limit change.
After seeing that via a CC in ADODD’s correspondence, we followed up with Curtin, first to ask if there’s a specified width for the resulting, narrowed traffic lanes: “Travel lanes will be 11 to 12 feet wide depending on the location to match the existing edge lines on the corridor. The roadway channelization will look very similar to the existing conditions on Delridge between Croft Pl SW and SW Myrtle Street.” (That’s where we took the photo atop this story.) He added that “the edge line will be applied to both sides of the street. Bike lanes are not planned through this low cost effort.” No existing markings will be changed, according to Curtin, just “essentially filling in the gaps in the channelization so we will not make changes to existing pavement markings.”
Our last question: What about the other arterials set for speed-limit reduction? Curtin replied: “Fauntleroy between Alaska and California will occur first – likely within the next month or so. The speed limit is already 30 mph along most of Fauntleroy but the speed limit jumps up to 35 in this section (which contains mainly residential land uses, Fairmount Park Elementary, and a park). Speed studies show that drivers are already traveling well below the existing 35 mph speed limit on this section of Fauntleroy. We intend to recalibrate the radar speed sign at SW Brandon Street and change the existing speed limit signs. As you know, the design of the roadway was significantly changed in 2009.” The 30 mph speed limit for more arterials was first announced last February.
