Readers Ask: Recommending bioswales

The second post in “Readers Ask,” from a planning student in Chicago.

I want to recommend bioswales for my Complete Streets project area which consists of a part of Grand in Chicago, Illinois  There are a lot of surface parking lots over there, and a big shopping mall which is built on a weird arrangement of slopes (Brickyard).  Since I know nothing about bioswales, I’m wondering what you could tell me about how I could go about recommending this. I have no idea what the rainwater runoff issue is over there, but I could only imagine that there would be one, with all the surface parking and weird slopage.

Bioswales are just one of many solutions to water runoff and stormwater collection. Another option is using permeable pavers in the parking lot. The real experts on this are Janet Attarian and David Leopold at CDOT. As a project manager at the Streetscape and Sustainable Design Program, he’s dealt with and implemented bioswales, permeable parking lots, and pollution fighting bike lanes – the works. There’s a parking lot, designed by CDOT, built with a bioswale AND permeable pavement on Desplaines between Polk and Taylor in Chicago (photo below)/

EVERY parking lot has runoff – every parking lot should do a better job managing it. By not better managing our stormwater, we all pay the costs, be it through flood insurance, recovering from floods, or having to build bigger pumps and sewers.

Perhaps you shouldn’t recommend a bioswale, but a parking lot that “captures 80% of its runoff” or something through a “variety of methods.”

The EPA lists additional Best Management Practices. The Cities of  Seattle and Portland are experts in this. Portland was even able to get parts of its bikeway built by rolling them into the Department of Environment’s Green Streets program, their efforts to reduce stormwater runoff and thus reduce the costs they pass on to their customers that pay for sewer service (like, everyone). I recommend this blog article about Portland’s sustainable design, written by a fellow planning student.

Introducing Grocery Store Bike Parking Ratings

This article is part of a series (it seems) of grocery stores with poor bike parking – it first started with my local Dominick’s. I started an inventory and rating system for Chicago. I welcome your contribution. If you want to start a page for your town, I can help you with that.

After seeing the photos of the wacky bike parking situation at the Lincoln Park Whole Foods on Ding Ding Let’s Ride, I had to take a trip there myself!

By my count, I find that with 3 wave racks (of 2 sizes) and 3 grill racks, there are 27 bike parking spaces. You can debate me and possibly find 4 more.

Surely you can fit more, just like you can fit 4 bikes on a 2-space Chicago u-rack.However, the racks are installed so closer together to make this area quite a pain to find a space. And if you have a long wheelbase cargo bike (bakfiets, Madsen, or Yuba Mundo), GOOD LUCK!

The only space available for a longtail cargo bike like my Yuba Mundo is in a car parking space next to a hybrid Chevy Tahoe illegally parked in a handicapped parking space.

But officially, for planning purposes, the Chicago Department of Transportation considers that rack as only fitting 2. This area could easily be sheltered. I think it’s something the store should look into. It provides sheltered car parking, which costs proportionally more than sheltered bike racks!

In the future, I expect better from Whole Foods.

For now, Target takes home the cake for providing consistently “good” bike parking. (Great’s the best a store can achieve.) So far, the rating system isn’t fully formed or automated. It’s a work in progress!

Sidenote: Access to Whole Foods via bicycle really sucks. There’s a 5-way intersection controlled by stop signs; then there’s the old railroad track and potholes. It might be better if you come in from the south, but then you have more RR track to deal with.

Park wins while parking fails neighborhood

This post on the removal of car parking at a park inspired me to write this post about the addition of car parking at a park.

Palmisano (Stearns Quarry) Park was created out of a dolomite limestone quarry and landfill in Bridgeport. The park is well designed and has a variety of landscape features. It’s quite popular, especially with elderly Asian residents.

Now, after a year of it being open, many diagonal parking spaces were installed on 27th Street. Space was removed from the parkway to create additional parking spaces where only parallel spaces existed.

Access to the park is not an issue. There are hundreds of households and thousands of residents within half a mile. There’re bike lanes and bus stops. There is a signalized intersection that makes it safer for people to cross the street to the park. Lastly, there are many unused parallel parking spaces lining two sides of the park.

So why was parking added? Did the neighbors ask for it? Did the Chicago Park District feel new parking was needed?

In a nutshell, my complaints against this are:

  1. It removed parkway – this should be sacred space. Perhaps we can institute a “tit-for-tat” policy (modeled after a parking meter agreement*) where if parkway is removed in one place, parkway has to be expanded or improved in another place.
  2. Potentially increases traffic in area by encouraging more driving by offering free parking. All parking surrounding the park is free.
  3. Parking space for drivers with handicap badges does not have a ramp. This is the most perplexing part – you may have to open the photo to its full size to notice this.
  4. Bumpout is not a bioswale. I highly doubt anyone will maintain the grass and soil. This landscaping will die.
  5. Bumpout’s large radius will not calm traffic (I watch it every day).

I would like to see the bumpout “island” transformed into a proper curb extension at a stop sign where drivers typically pause in the crosswalk and quickly turn right into southbound Halsted without stopping. I would like to see a bioswale collect the water from the street at this curb and divert it to the park’s wetlands.

*As I understand it, if parking meter spaces are removed and converted to another use (like a curb extension or on-street bicycle parking), a non-metered space must be converted to the equivalent metered spaces removed.
