Bridge Repair – Next in Line

The Doctor Jose Rizal Bridge, one of two bridges with rehabilitation work beginning late 2009.

The Doctor Jose Rizal Bridge, one of two bridges with rehabilitation work beginning late 2009.

If you’ve been reading the blog with us for a while you know that, just like growing apples and cherries, paving streets and sidewalks in Seattle is a seasonal activity. Paving and rain don’t mix well, and we got a taste this weekend of the rainy days that are soon to come.

But that doesn’t mean that there’s no field work to get done in the coming months.  As paving projects wrap up this fall, two of our Bridging the Gap-funded bridge rehabilitation, replacement and seismic retrofit projects are moving into construction this winter: the Doctor Jose Rizal Bridge Rehabilitation Project and the 15th Avenue NE at 105th Street Bridge Rehabilitation Project.  Watch for work on both those structures to begin soon.

In honor of the bridge construction, here are few fun facts about Seattle’s bridges:

 1.  Over 16,000 bridge openings happen each year.  The Fremont Bridge has the least clearance and thus the most openings with over 6,000 each year.

2.  The Spokane Street Swing Bridge is the only double leaf, hydraulic, segmental concrete swing bridge in the world.  Each of the two spans weighs over 15 million pounds.  A nine foot diameter hydraulic cylinder (jack) is use to lift the bridge during each opening.

3.  The Ballard Bridge is 2,854 feet long.  It’s the longest City-owned bridge with pedestrian access.

Rain Gardening

14th Avenue NW at NW 58th Street

14th Avenue NW at NW 58th Street

Seattle is known worldwide as the Emerald City thanks to our lush, verdant landscape.  Of course we have Mother Nature to thank since she provides the 38 inches of annual rainfall that makes our city so green. 

So where does all that water go?  In urban environments like Seattle, most of our rain falls upon hard, impervious surfaces and is funneled into a stormwater conveyence system.  On its way to the stormwater system, the run-off picks up and carries pollutants like oil, sediments, and fertilizers which are ultimately deposited into to our lakes, rivers, wetlands, and the Puget Sound.

In an effort to enhance water quality, SDOT has started taking a greener approach when we design or retrofit facilities.  For example, the recently completed extended curb bulb project at 14th Avenue NW and NW 58th Street was designed to filter polluted run-off and allow rain water to infiltrate into the ground.  In this design there are depressed openings at either end of the bulbs that allow stormwater to flow into the landscaped area.  The vegetation slows the speed of the water allowing time for the water to percolate into gravel and amended soil which helps reduce the amount of stormwater runoff. Once the area becomes saturated, water exits the swale after the wetland plants filter the pollution particulates.  This type of facility is commonly known as a “rain garden”.

SDOT looks to incorporate green design standards in all of our infrastructure projects.  As we build more and more green projects throughout the city, these facilities will foster a deeper shade of emerald in our fair city and, ultimately, a healthier Puget Sound.

Handling Leaves Impacts Street Sweeping Results

Sourwood Tree

 All the colorful leaves lacing fall trees (and then the ground) are a gift that keeps on giving…in either a good, or a bad way. It all depends on how they’re handled. When residents rake leaves from their yards and sidewalks into the streets the extra load slows down street sweepers, reducing the number of streets that can be cleared. Of course, many people might think they’re being helpful by sweeping those leaves into the roadway, since it’s not common water cooler discussion that “littering” the street with leaves is illegal or that property owners are responsible for maintaining the sidewalks next to their property. So if you are at a water cooler, or other casual gathering, we ask that you chat with neighborhood newcomers not yet accustomed to the City’s disposal system about “proper leaf-raking and disposal etiquette“ (for more information, residents may call the Seattle Public Utilities at 684-3000).

For the gift that keeps giving in a GOOD way, that autumnal yard waste can contribute to environmental rejuvenation – either in your own backyard compost or as part of a larger effort. For really large loads, residents may haul the yard debris to one of the City’s two Recycling and Disposal stations, both of which have special areas for “clean green.” Proper leaf clearing also reduces flood risks. During intense rain, flooding may occur without warning so don’t put grass clippings, leaves, or other debris into drains, ditches, creeks, culverts, gutters or ravines and if a storm drain appears blocked below the street surface, call (206) 386-1800. Want to do more? You can officially adopt a drain in need and be a neighborhood hero! Visit Adopt-A-Drain for the details. Thanks all and enjoy the fall!

Shrinking Big Foot

BGFT_TYPEFOOTShrinking BigFoot is kicking off in schools this week.  It is a really fun workshop for elementary school kids to empower students to shrink their carbon footprints with easy, everyday actions. Check out the “preview” video here. Seattle City Light and SDOT created the program.  Did you know that driving is the largest source of global warming in Seattle?  It is responsible for almost 60% of Seattle residents’ “carbon footprint”.  SDOT partnered with CoolMom, a nonprofit group of moms concerned about climate change, to make fortune tellers for kids highlighting their cool carbon future.  Remember those fortune tellers you used to make out of paper FortuneTellerFold? You can download the fortune tellers here and here to make your own. For a kids’ Top 10 list of tips to reduce your carbon footprint, visit our Way to Go Seattle! Shrinking Bigfoot webpage.

Did you know if every Seattlite drove about 20 miles less per week we could meet our goals to reduce GHG?  Here are some ideas of ways to drive 20 miles less per week.  It all adds up to make a difference.

We’re With You on the Road

Many travelers prepare early for the morning and evening commutes by watching or listening to the news for regular traffic updates. While this is usually helpful, you sometimes need information in between the traffic forecasts. One way SDOT gets this information to you is through dynamic messaging signs. You’ve likely seen these digital display boards on the freeway and major streets. When there is important information to share, we can send a message to the signs that helps travelers make more informed decisions on the road. Messages may be about special events alerts, roadway closures, traffic accidents, heavy congestion or a number of other travel concerns. SDOT currently has six dynamic messaging signs, but has plans to install 12 more next year. Stay informed and drive safely!

Walk this Way

DT Peds & Signal1Walking is the oldest and most efficient, affordable, and environmentally-friendly form of transportation—it’s how transit riders eventually reach their destinations, how drivers get from the parking lot to the front door, and how cyclists get from the bike rack to the business.   Nearly everyone, for at least some portion of every day, is a pedestrian. That is why (as most of you know) we developed Seattle’s first Pedestrian Master Plan, approved by the Mayor and Council late last month.

Since it’s gotten so much press from traditional media outlets, we nearly forgot out blog readers might also want to take good look at the plan.  You can check it out here.

Ramping Up

After (looking east)

 

Curb ramps, also known as wheelchair ramps, are critical to providing access between the sidewalk and the street, but they’re not just intended to help people in wheelchairs.  Everyone benefits when curb ramps are installed whether you are pushing a stroller, riding a bike, or simply walking around your neighborhood.  

Curb ramps are required at each intersection by the Americans with Disabilities Act (ADA) of 1990 so it is our job to ensure that ramps are present at every one of our 10,000+ intersections.  And we’re ramping up our efforts to do just that. 

SDOT’s ADA Program will construct over 1000 new curb ramps throughout the city over the next two years and our capital improvement program will construct nearly 1000 ramps as well.  Our primary focus is to construct ramps at locations where no ramps exist but we also retrofit hundreds of curb ramps each year to ensure compliance with federal standards. 

We’re making considerable progress towards equipping all of our intersections with curb ramps, and in the process, eliminating mobility barriers and improving our pedestrian system.

Quality in the Details

The SDOT paving program has been rolling full speed ahead all season, with plenty of concrete, asphalt and paint, but it doesn’t stop there.

We’re also continuing the Seattle tradition of inlaying the street names in brass on corners downtown. You’ll notice them in the retail core and some other locations in the central business district. We know that quality in a transportation system comes at all levels, from efficiently moving thousands of bikes, people and cars through a busy downtown intersection to smaller touches like the brass inlays.

We hope you notice and enjoy them!

Meet the Talent

Forch 008 (rs2)

Last month, Tabor 100 recognized SDOT’s Bobby Forch with their 2009 Crystal Eagle Award for Business Development. He serves as the women & minority business enterprises (WMBE) contracts advisor, working to ensure contracts are equitably awarded for SDOT and other City of Seattle projects. Tabor 100 is a grassroots economic development coalition dedicated to ensuring opportunity for minority businesses. Bobby, who has worked for the City for over 20 years, was recognized for his role in creating economic development opportunities for underrepresented businesses.

Working to promote productive and inclusive principles is something he has done during his time with the City. His work has focused on our contracting standards and our outreach to the Seattle business community. Among his contributions are his work on a city ordinance, which passed, requiring equity in contracting, and his work to develop tools that help SDOT project managers use wider pools of contractors that include minority businesses. While in his current role, SDOT has seen its utilization of women and minority businesses increase over 50% in the past three years.

Outside of SDOT, he is an active member of the community, working with the Northwest Children’s Fund to raise grant funds for charities benefiting youth and serving on the board of the Seattle Management Association, among other activities.

Influenced by the positive impact of economic equity on Seattle’s minority businesses, Bobby continues to work on improving our community engagement efforts and our contracting processes. We are proud to have him on our team!

I can see for miles and miles

Mt Rainier2

Did you notice how clear Mt Rainier was yesterday?  Well, we have some good news.  According to the Puget Sound Clean Air Agency; we can see much farther than we could in 1990.  The average visibility for the Puget Sound area has steadily increased over the last decade (with year-to-year variability caused by meteorology).  For the 18 year period from December 1990 through December 2007; the visual range (based on a 12 month moving average) increased from 46 to 75 miles. This hasn’t always been the case.   In 1990, Mt Rainier was one third less visible than it was 8 years before.  Auto pollution is one of the main reasons.  Many of us at SDOT work to make this city a place where you don’t HAVE to drive; and there are safe and easy ways to walk, bike, and take transit.   Part of our motivation is to help the city be more livable and walkable to protect the environment (and mountain views) we all love.   The reason visibility has improved is due to a variety of factors, including reduced wood burning, but also cleaner burning cars and how we drive.  Now all we have to do is fix this climate problem, and we’re all set.
