Since I posted an article about new, non-auto infrastructure projects in Chicago, a lot of people looking for information on the 31st Street Harbor (now visibly underway) have come across my blog. For them, I give this update.

A new breakwater and new piers will be built. I really want to know what the floating eyeballs are for. I imagine they’re markers for construction.

I was counting people entering the Lakefront Trail from the 31st Street access point yesterday for an Active Transportation Alliance project. Afterwards, I moseyed over to get a glance at the construction.

This photo shows how the pier has been closed for construction. I hardly see anyone using the pier except just to walk down and back – it seems few people fish here.

I’ve written several papers on congestion and road pricing*. The most common type seen in the United States is HOT (high occupancy tolling) lanes. This is where drivers can pay to use uncongested lanes; drivers who carpool may use the lane for free or at a discount. Transit buses can always use the lane for free.

From the University of California Transportation Center comes new research on paying for roads with congestion versus paying for roads with sales taxes and their respective burden on poor residents.

Will research show that more people will benefit from paying sales tax to support a transit system than from paying (all kinds of) taxes to support a highway?

Their finding is that funding transportation with sales tax is less fair than funding with congestion pricing. In the latest issue of Access, Lisa Schweitzer and Brian Taylor write:

This analysis has focused on one side of the ledger: the question of who pays. But transpor tation systems have both costs and benefits. Indeed, the access benefits of travel are transportation’s raison d’être. So while regressivity can be viewed as a cost of road pricing (and of most other ways of paying for roads), pricing confers transportation benefits that other transpor tation finance mechanisms do not. Tolls and taxes can both pay to build a road. But congestion pricing can also reduce traffic delays, fuel consumption, and vehicle emissions, often to a surprising degree. Sales tax finance for transportation, by comparison, does none of these things.

I think the appropriate direction of this research should next discuss and examine the fairness of using sales taxes to provide operational and capital funding for transit. In Chicagoland, the Regional Transportation Authority is partially supported by a local sales tax. While sales tax financing for road building may not reduce traffic delays, fuel consumption, or vehicle emissions, supporting a reliable, robust and expansive transit network can do all of those things by reducing the number of single occupant vehicles on the road.

*Oddly I haven’t posted any of them here.

West North points out that instead of spending $8 billion to build new sewage holding tanks throughout the city, the Philadelphia Water Department plans to conver impervious surfaces to pervious, natural surfaces. The American Society of Landscape Architects has more information on The Dirt:

The green infrastructure proposal would turn 1/3 of the city’s impervious asphalt surface, or 4,000 acres, into absorptive green spaces. The goal is to move from grey to green infrastructure. Grey infrastructure includes “man-made single purpose systems.” Green infrastructure is defined as “man-made structures that mimic natural systems.” As an example, networks of man-made wetlands, restored flood plains, or infiltration basins would all qualify as green infrastructure. The benefits of such systems include: evaporation, transpiration, enhanced water quality, reduced erosion / sedimentation, and restoration. Some grey / green infrastructure feature integrated systems that create hybrid detention ponds or holding tanks, which are designed to slow water’s release into stormwater management systems.

And, like Portland, Philadelphia is accomplishing more than just better stormwater management.

…the city is calling for a triple-bottom line approach, aiming for: more green spaces, improved public health, and more green jobs. [The Dirt]

Portland is building “Green Streets” that combine bicycle facilities with green infrastructure like bioswales inside curb extensions. This plan did not arise perhaps as altruistically as Philly’s (actually with a little controversy), but more as a way to build bicycle facilities with bioswale funding.

Meanwhile, the Deep Tunnel system in Chicago continues to expand. But it’s not all bad. The City of Chicago will showcase green infrastructure in a new streetscape in the Pilsen neighborhood.

60 billion gallons of rain fell on Cook County on Friday night, according to the Metropolitan Water Reclamation District’s (MWRD) president Terrence O’Brien.

That’s enough to fill 1.2 billion of these Suncast rain barrels*. The rain was too much for the Deep Tunnel – the underground network of  water reservoirs. They hold water runoff during storms before it goes to the water treatment plant for cleaning, after which it will flow into one of the water channels in and around Chicago. But the storms on Friday were too much – the MWRD had to release sewage into Lake Michigan because the reservoirs were full.

This in turn forced the Chicago Park District to close the beaches.

“All 109 miles of the Deep Tunnel system were filled during the storm, O’Brien said.”

We find ourselves in a situation similar to that of traffic congestion. Building new and wider roads doesn’t relieve traffic congestion. The same might be true for Deep Tunnel construction. Longer and wider tubes won’t reduce our water usage or how much stormwater is directed to the sewers (Chicago has a combined sewer, draining sewage from buildings and stormwater from the street). The Chicago Tribune article doesn’t exactly point out the solution, and it only hints at the problem: We get more water in our tunnel than we can handle.

The Chicago Harbor Lock separates the Chicago River from Lake Michigan was opened to allow the river to discharge its overflow into the lake. The water at Chicago’s magnificent beaches could have been contaminated so the Park District closed swimming at ALL beaches until at least Monday morning. Photo by Norma Fernandez.

Chicagoland needs a better stormwater management plan that incorporates sustainable best practices. We can start by encouraging landscaping that absorbs stormwater instead of acting like a slope towards the nearest drain. New streetscape projects can have bioswale planters. What other ideas are there to reduce the amount of runoff that has to be stored in hundreds of underground tunnels?

*The MWRD sells rain barrels to the public online for pickup. Rain barrels are just one part of a multi-pronged solution to stormwater management.

UPDATE: A Tribune story from today about suburban transit is sizzling: “A majority of Chicago-area residents think improving bus and train service is so important to the region that repairing and expanding expressways and toll roads should take a back seat…” Continue reading.

I listed several transit projects happening or about to happen (17 of ‘em) in the Chicago city limits, but Ted Villaire writes in the Active Transportation Alliance’s current newsletter about some suburban transit projects underway.

The station in downtown Geneva, Illinois, will see longer platforms and better delineation of waiting areas and crossing paths. Additionally, the operating railroad (Union Pacific), Metra, and the City of Geneva are working to expand the parking options – it’s about time that Geneva works on a bike plan. There are thousands of residents with a couple miles of the station and the station is near two major multi-use trails.

• Skoke – New Yellow Line CTA station at Oakton Street.
• Winnetka – Refurbished Metra UP-North station.
• West suburbs – Track and station upgrades at many UP-West cities.

The UP-West line will receive an exciting, new and visible safety upgrade: Another Train Warning System. This product serves to alert those travelers who seem to distrust the accuracy of warning bells and gates by explicitly announcing the presence of an incoming train. The device visually and audibly alerts passengers of the existence of another train in the platform and station area.

All Metra enhancements should be done by 2011.
