How Much to Invest in I-405 BRT

Posted on by Dan Ryan
Sound Transit has agreed to add a BRT stop with 200 surface parking stalls at NE 44th in Renton

After Sound Transit released the draft system plan in March, some Eastside cities were unhappy it included a smaller investment in I-405 BRT than they had sought. Bellevue and Renton pushed for something closer to the “intensive capital” BRT with more parking and more stations using express toll lanes.

Some Eastside cities penned a joint letter, describing the proposal as comparable to ST Express service with improved headways, and demanding a much larger investment with more inline stops to create a BRT that is “the equivalent of light rail on rubber tires”. The attempt to forge a coalition of the I-405 corridor cities fell flat. Several East and South King cities did not sign. Some who signed were small cities that do not border I-405. None of the Snohomish County cities participated.

The amended system plan made some concessions. Sound Transit had agreed in March to relocate Renton’s downtown transit center to a more freeway-accessible location with 700 parking stalls. Renton pushed to expand the new South Renton transit center to accommodate 2,000 cars, and to add a second BRT stop at NE 44th St with parking for another 700. While the Board agreed only to 200 parking stalls in a surface lot at NE 44th St, the added center-line direct access facility adds $170 million to the cost of the BRT. An even more remote station with expanded parking at SE 112th in Bellevue was not included. Kirkland, taking a different approach, negotiated for more TOD in Kingsgate, reducing by 200 the planned parking expansion there.

I-405 BRT had lots of institutional momentum. The master plan for I-405, approved in 2002, envisions a BRT line with inline stations along I-405. To this end, Sound Transit has built transit centers and center ramps to the HOV lanes. WSDoT has created the express toll lanes north of Bellevue where buses could move reliably. With WSDoT now funded to extend the express lanes to the south, many observers expected a large investment in BRT on the corridor in ST3.

The plan ran up against uncomfortably low ridership numbers. Modelling suggests only 12,000 riders in 2040, and that the ridership isn’t increased at higher investment levels. A pared-down BRT, much of which runs in general traffic lanes, attracts as many riders as the ‘Cadillac’ version.

Recognizing that the proposal for higher investment levels didn’t stand up to close scrutiny, the Sound Transit Board in March advanced a draft system plan with just $735 million in capital investments, less than any of the options considered in the 2014 corridor studies. The low capital plan leveraged existing highway infrastructure with better and more frequent buses. Where center stations already exist, the BRT would run in the ETL lanes. Elsewhere, buses would run in general purpose lanes (or on the shoulder in a few locations north of Bothell).

Extending Rail to South Kirkland

Sound Transit and Kirkland are considering a possible light rail station at the South Kirkland Park-and-Ride. After the draft system plan was released on March 24 without the hoped-for service to Kirkland on the Eastside Rail Corridor, the Eastside Board members wrote the city suggesting study of a short rail extension to South Kirkland. Staff analysis on both sides is underway.

Preliminary analysis envisions extending the planned Issaquah line from Wilburton to South Kirkland along the ERC. The travel time to Bellevue would be 7 minutes. The extension would cost $307 million, serving 2,500 daily riders, perhaps truncating some Metro routes. A 500-stall parking structure would add another $28 million to the capital cost.

The symbolic relevance of the proposed station is obvious. For Sound Transit, it suggests the Issaquah-Totem Lake rail line will be completed in ST4 (the draft plan also includes an environmental study of transit on the corridor). For Kirkland too, it’s an affirmation the city will finally see high-capacity transit in ST4, though rail rather than the BRT which the City expects would be more productive. For homeowners who opposed transit “on the trail” in ST3, it means transit plans were not defeated, only deferred.

Pending a future transit package, how would the spur line fit in the network? After all, this could be the terminus of the rail line for a long time. There are some obvious questions:

Is South Kirkland a viable destination? The planned station mostly targets riders arriving via Metro routes from the north, along with drivers to the expanded parking facility. Current local land use is primarily office with extensive surface parking and little near-term redevelopment in the pipeline. On the other hand, proximity to Bellevue will surely help redevelopment before rail service begins (anticipated at the very end of the ST3 program in 2041). Zoned heights on the Kirkland side of the station max out at 65′. But, with few residential neighbors and an adjacent highway, the path to more aggressive zoning may not be difficult.

Added parking comes with well-understood trade-offs, but replacing some of the existing surface lot with a 500-stall garage would hardly be decisive. Both Kirkland and Bellevue (the P&R is mostly within Bellevue city limits) should be having a land use conversation, even if Sound Transit’s immediate analysis must rely on current PSRC projections.

What does the transit network map around a South Kirkland rail station look like? Most riders to Seattle would prefer a cross-lake bus to UW station in any scenario. Kirkland-Bellevue riders will be served by Rapid Ride (by 2025 per the Metro LRP). Would that be improved upon by having riders exit the bus to a train, with the associated transfer penalty?

Kirkland’s Compromise ST3 Offer

Posted on by Dan Ryan
One reason to favor BRT is that the nearest proposed light rail station would be 0.5 miles from downtown and surrounded by low-density uses.

On Tuesday evening, the Kirkland City Council approved a letter to the Sound Transit Board offering a compromise to resolve the impasse over transit on the Cross-Kirkland Corridor (CKC). The letter (significantly revised from the draft Zach reported on Saturday) seeks an investment in trail access from Kirkland to the Wilburton Link Station and Kingsgate BRT station. These trails would be designed to accommodate transit, carefully signaling the integration of transit and other uses on the corridor. At the same time, ST3 would fund planning and development for high-capacity transit on the corridor, leading to a record of decision for transit in the next regional package.

The “Kirkland Compromise” includes:

  • A Regional Trail connection from Sound Transit’s Totem Lake terminus to Sound Transit’s Wilburton Station in Bellevue along the CKC and ERC. This would be a fully developed permanent trail built to the specifications of the Cross-Kirkland Corridor Master Plan in Kirkland and King County’s ERC Regional Trail Master Plan in Bellevue.
  • Trail planning aligned with transit planning to clearly define a future transit envelope in the CKC and ERC in Bellevue. Planning the trail and transit together ensure the trail would not be disrupted in the future.
  • Design money allocated for transit design on the CKC/ERC to achieve a record of decision.
  • BRT on I-405 to include an inline station at NE 85th along with transit service directly connecting downtown Kirkland to Redmond along NE 85th in exclusive lanes.

The Eastside Rail Corridor Regional Trail Starting to Take Shape

Posted on by Dan Ryan

Last week, King County Parks published a draft master plan for the Eastside Rail Corridor Regional Trail. The County aims to develop a permanent paved trail on over 16 miles of the corridor.

As the trail plan enters a public comment period, Sound Transit is finalizing its own draft system plan. That will clarify how portions of the corridor may be shared with transit. Across the Eastside, efforts to bring the corridor into public use are accelerating. Legacy freight tracks will be removed in 2017, and trails are being expanded. Snohomish County has agreed to buy 12 miles of corridor and is expected to build a trail alongside the active rail line. A once contentious political debate over rails vs trails has been mostly replaced by a consensus that the ERC will serve both (though it still echoes in Kirkland where transit opponents have coalesced around “Save Our Trail” rhetoric).

Since being rail-banked in 2009, ownership has resided with several jurisdictions. The cities of Redmond and Kirkland mostly own the segments within their respective city limits. Sound Transit owns a 1-mile section where East Link will be built. The balance of the rail-banked area is owned by King County. The County is also the trail sponsor in the Sound Transit area. Sound Transit and other utilities retain easements along the ERC. Owners and stakeholders collaborate through the ERC Regional Advisory Council.

Here’s a flavor of what’s going on: Continue reading “The Eastside Rail Corridor Regional Trail Starting to Take Shape”

Where Now For The Water Taxi Expansion?

On February 8, the King County Council accepted the final report on Water Taxi expansion. The Council vote followed an occasionally contentious review at the TrEE (Transportation, Economy and Environment) Committee the week before. No decision was taken on moving forward with the expansion. That’s a budgetary decision to be taken up, if a request is made, as part of the budget process later this year.

The final report refines analysis presented in the interim report, and accommodates some suggestions by the jurisdictions and stakeholders that might be served. But the key findings haven’t changed greatly. Three routes are being considered:

  • Kenmore (Log Boom Park) to University of Washington (Waterfront Activity Center)
  • Kirkland (Marina Park) to University of Washington (Waterfront Activity Center)
  • Ballard (Shilshole Marina) to Downtown Seattle (Pier 50).

A few modifications are suggested. In Kenmore, the ferry may eventually serve Lake Pointe where development could create an opportunity for shared parking (initial service would be via Log Boom Park with parking at a remote lot served by shuttle bus). In Kirkland, where downtown parking for transit riders would not be available, a circulator shuttle to bring riders to the Marina is examined. Expedia has asked that the ferry from Shilshole Bay stop at Interbay en route to downtown Seattle.

The revisions to the proposal do not improve expected performance. These are low-ridership high-cost services. At launch, off-season ridership would range between 135 and 165 daily riders per route, growing to 285-370 after 10 years. Summer ridership, boosted by recreational users, would grow from about 300 daily riders on each route to just over 500 after 10 years.

East King County’s ST3 Letters

This summary of ST3 feedback from East King County (including North King other than Seattle) is the fifth in a series of ST3 feedback summaries. See our previous coverage of Pierce County, Seattle, South King County, and Snohomish County. A future installment will look at other Stakeholder Organizations.

The Eastside’s ST3 input is well coordinated. As happened last July, several Eastside cities signed a joint letter describing shared goals. Cities along the SR 522 corridor also submitted their own joint letter endorsing BRT on SR 522 and NE 145th St. Read together with the cities own letters, there’s an impressive consensus about what an Eastside ST3 package needs to look like.

Joint Letter of the Eastside Cities

The Eastside cities introduce their priorities by noting how they are “reshaping our regional growth centers and downtowns into dense, mixed-use, urban centers that need frequent and reliable transit service to sustain economic growth and viability. ST3 has the potential to create transit connections within the Eastside, and provide connections between the Eastside and the rest of the region”. The letter goes on to remind the Board that “the Eastside will be making a significant tax investment into the package” and looks forward to seeing commensurate investments back into the Eastside.

The Eastside’s five priorities in ST3 are:

  • E-01: Completing the East Link spine to Downtown Redmond. This is so uncontroversial that no explanation was apparently necessary.
  • E-02: Fully implement Bus Rapid Transit (BRT) on I-405, from Lynnwood to SeaTac. A version of I-405 BRT between the low and intensive capital versions is recommended. The scope needs to “provide sufficient access for the line to operate as an efficient BRT facility”. That means an inline station at NE 85th Street in Kirkland, direct access to Tukwila Sounder Station, at least one additional location south of I-90, and a dedicated transitway with inline flyer stops. The latter implies a significant investment in South Snohomish County where the BRT would otherwise run in mixed traffic north of SR 522.
  • E-03: Light rail from Totem Lake to Issaquah via Bellevue. In an acknowledgment that BRT may have advantages in Kirkland, the joint letter caveats that “this project must provide flexibility and be scalable to meet ridership demand and the needs of the communities served”.
  • E-04: A new transit center in Renton at Rainier Ave S and S Grady Way. This project would replace the downtown transit center.
  • N-09 and N-10: BRT on 145th Street and SR 522 to connect with North Link.

ST3: Kirkland-Issaquah Light Rail

Posted on by Dan Ryan

E03Map

Not so long ago, prospects for an ST3 investment in rail from Totem Lake to Issaquah seemed remote. There were too many competing priorities within a 15-year ST3 program, making a deferral to ST4 likely, and motivating examination of BRT between Bellevue and Kirkland. In an extended program, it’s suddenly feasible, but the proposed alignment has weak connections to the most important destinations.

The project is a 17.5 mile rail line from Totem Lake to Central Issaquah connecting nine stations. From the north, the line generally follows the Eastside Rail Corridor, briefly interlining with East Link near Wilburton station. This is also a transfer point to East Link trains serving downtown Bellevue or Seattle. Near the historic Wilburton trestle, the line transitions to the east side of I-405 and then to I-90 in Factoria. Beyond Factoria, the line generally follows the I-90 median to a terminus in Central Issaquah.

There are eight new stations, four each on Segment A (Totem Lake – Wilburton) and Segment B (Wilburton – Issaquah).

Segment A serves four stops in the Kirkland area. An added stop at NE 112th St means this is one more than the previous studies, improving access within the southern part of the Totem Lake neighborhood. Other Kirkland stops are at NE 128th St (adjacent to the freeway BRT station), at NE 6th St (southeast of downtown), and at the South Kirkland P&R.

Segment B also serves four stations (after Wilburton); in Factoria, at Eastgate, at Lakemont Blvd, and in Central Issaquah. The Factoria and Lakemont stops are new to this study. The Factoria station, near Richards Rd on the north side of I-90, will improve access along the Eastgate/I-90 corridor which seems too sprawling to be well served via Eastgate alone. While the location isn’t ideal for Factoria riders, it’s perhaps as close to Factoria as the line can get while avoiding the environmental and engineering challenges of Mercer Slough and the I-405 interchange. The added stop at Lakemont would be a park-and-ride facility.

Kirkland may not be impressed by a Kirkland-Bellevue rail segment lacking walkable access to the downtown of either city. Issaquah, on the other hand, intends to concentrate future growth within the Central Issaquah area adjacent to  the planned station. Travel from Issaquah to Seattle via Wilburton may appear circuitous, but no more so than express buses terminating into Bellevue Transit Center.

ST3: Bus Rapid Transit on I-405

Posted on by Dan Ryan

I-405 BRT Corridor Options

There has long been a regional consensus that I-405 Bus Rapid Transit would be a part of the ST3 program. But that general agreement has hidden a fuzziness about the form it would take. The December 4 workshop saw a range of options presented. The studies make a compelling case for a low-cost version of I-405 BRT, but complicate the case for doing much more. The eye-popping conclusion is that a range of investment levels between $340 million and $2.3 billion all produce the same ridership.

Staff presented “low capital” and “intensive capital” representative models. In between are a long list of a la carte options. There are two alternatives for a southern terminus; one at Angle Lake, the other at Burien TC. The “low capital” model leans heavily on existing infrastructure, and is less ambitious than any of the options examined in the previous set of studies in 2014.

Low Capital BRT

Staff analysis helpfully breaks out cost and performance by segment. Segment A, Lynnwood TC to Bellevue TC, is the most productive with up to 10,000 riders, about 60% of all the ridership on the BRT. 10 of the 19 miles are served via general purpose lanes on I-5 and I-405 (other than limited shoulder-running southbound on I-405). Only the portion between Brickyard and Bellevue can be served via HOT lanes. Segment B, Bellevue to Renton, runs entirely in HOT lanes, but achieves fewer than 1,500 riders. That would include a deferred project to build HOV direct access ramps at N 8th St in Renton.

Beyond Renton, there is little new investment. Segment C, Renton to Tukwila International Boulevard Link Station, would run in HOT lanes on I-405 and general purpose lanes on SR 518, achieving a respectable 3,500 riders with little cost other than vehicles. From TIBS, the service could continue to Angle Lake via BAT lanes on SR 99 (Segment D1), or to Burien Transit Center via general purpose lanes on SR 518 (Segment D2).

The total capital cost under $350 million is modest for the ridership, mostly because the highway infrastructure is largely existing or funded through WSDOT. 28% of the cost is for parking.ST3_i405BRT_Elements2

Intensive Capital BRT

The ‘intensive capital’ option adds several stations and upgrades others. It eliminates much of the interaction with general purpose lanes via added ramps in the north and BAT lanes in the south.

ST3: Kirkland-Bellevue Bus Rapid Transit

Posted on by Dan Ryan

At the December 4 Board workshop, Sound Transit staff shared their latest study of Bus Rapid Transit along the Eastside Rail Corridor between Bellevue and Kirkland. The study parameters incorporate many suggestions from the City of Kirkland. Ten miles of mostly at-grade BRT guideway connect nine at-grade stations: three are in the Totem Lake area, two around downtown Kirkland, one at South Kirkland, and three more in Bellevue.

E06_MapThe corridor BRT is well-integrated with regional services. It would connect to I-405 BRT at Kingsgate/NE 128th, to East Link LRT at Wilburton Station, and to regional bus services at the Bellevue Transit Center. An alternative configuration at Wilburton might have an elevated station.

The study acknowledges the need to accommodate the existing trail on the Cross-Kirkland Corridor, and a future trail on the Eastside Rail Corridor in Bellevue. It specifies that the rail would be on the east of the corridor with trail uses to the west.

ACTION ALERT: Attend Kirkland’s ST3 Open House!

Posted on by David Lawson

Metro 236
Metro 236 near the Eastside Rail Corridor in Kirkland’s Totem Lake neighborhood

Kirkland residents and workers, and anyone else interested in the future of mobility in Kirkland, should attend the City of Kirkland’s ST3 open house tomorrow night (Thursday, Nov. 19).  The open house is at the Kirkland Performance Center in downtown Kirkland, one short block from Kirkland Transit Center, from 6:30 to 9:00 p.m.  Frequent Metro bus routes 234/235, 245, and 255, as well as other routes 236, 238, 248, and 540, all serve the location, with one-seat service from throughout the north Eastside as well as downtown Seattle.

Attending this meeting is critical because the city of Kirkland needs to hear support for rapid transit service along the Eastside Rail Corridor (ERC) between Bellevue and Totem Lake, which is the only realistic option for fast and frequent transit that will serve Kirkland communities. Full background below the jump.
