Existing green roofs can give us lots of information for future sustainable design, as long as we take care to monitor them carefully.

It’s a bird! It’s a plane! It’s a 12 percent increase in relative humidity!

… is something you’ve never said.

Yet perhaps you would if you had an amazing green roof monitoring station. (Ahem, like the one we just installed on a municipal building in the Village of Orland Park. Not to brag.)

The ability to monitor green roofs is an important one, and one that we here at Ecogardens have been pushing for some years now. Taking the time and spending the extra money to add in monitoring capabilities to green roofs can bring us a wealth of knowledge and significantly increase the value of green rooftop infrastructure.

Here’s why it matters and how you can monitor green roofs effectively.

Urban ecology is tough to define and tougher to agree on, but we have to do so if we want to make real strides in favor of life in our cities – including our own.

If someone asked you to offer a comprehensive urban ecology meaning, would you know what to say?

If your answer was something along the lines of “like, life in cities?” then join the crowd. Even people in the ecological and sustainability spaces have a hard time offering a true urban ecology meaning. The topic of life in the built environment is a big one, and we often forget crucial aspects of the definition.

Where we’re not forgetting things, we’re disagreeing on them. It’s a problem, especially when we try to sum up the concept in a single sentence, which often does more harm than good.

We’re not blameless here at Ecogardens, which is why we’ve been working hard lately to develop a more well-rounded urban ecology meaning and share it with our followers.

Stormwater management is a pressing need in today’s built environments, but it’s important to choose the right one for maximum effect. Here’s how to get started.

We’re just going to come right out and say it: stormwater sucks.

In an unmanaged urban context, at least, it can prove very damaging indeed.

“Increasing development and urbanization of our lands has led to changes in the natural environment that include increases in flooding, degradation of water quality, erosion, and sedimentation of our waterways,” says the University of Virginia’s Facilities Management Department.

Why is this happening? Because our heavily paved-over cities have cut off many of the avenues from sky to water table. Time was, when it rained or snowed, that water found its way to the closest stream or river pretty quickly, or else filtered through soil and other organic substances and joined the aquifer (the saturated area beneath the water table).

Now, that’s no longer possible in urban areas – or at least far more difficult.

Instead, water sheets off city surfaces – brick, stone, cement, asphalt – and eventually into waterways, but only after eroding the environment, spreading disease from sewers, and picking up massive chemicals loads from dirty city surfaces.

Good times.

Kidding. Terrible times. That’s where a good stormwater management system comes in.

While sedum has a formidable reputation when it comes to green roofs, there are a variety of other plants that offer competitive benefits.

Ask most people, and they’ll tell you there aren’t many alternative plants for green roofs. Sedum or bust, right?

Not quite. Actually, using native plants that complement the environment are a great approach, as long as you know which alternative species will work best for a particular rooftop environment and geographic location.

This becomes a bit more challenging on extensive green roofs, explains the University of Minnesota, pointing out that plant options are more limited when you have only 3-6 inches of growing media with which to work.

“Since there is less soil and the system as a whole has to be lighter,” they explain, “extensive green roofs are not able to support trees or shrubs like intensive systems. Instead, grasses and small plants are the available vegetation options for extensive green roofs.”

That said, there are quite a few plants that fit the bill – those aforementioned grasses or plants. See? We’re not nearly as confined to sedums as common perception holds.

Let’s take a look at our favorite alternative plants for green roofs today.

Chicago is a leading presence in the green infrastructure effort, especially here in the Midwest. Here’s a closer look at what the Windy City is doing to improve environmental issues like stormwater, urban heat island effect, pollution and more.

We all love a good role model.

Whether your idea of a powerful exemplar is Wonder Woman, Barack Obama or Chris Evans (too much on the superhero thing?), it’s nice to look up to someone.

We like to think Chicago is worthy of worship as well. You know, being all green and schtuff.

Seriously, though, when it comes to green infrastructure Chicago is taking a serious stand. Whether it’s working to bridge the gap between resilience and sustainability, or redefine how we use green infrastructure in the urban space, Chicago has decades of experience role modeling for the rest of us, and we’re so proud to be a part of that effort.

Making change, of course, starts with knowing as much as possible. If you’re interested in green infrastructure Chicago style, we’ve got your back.

Having a better definition of urban ecology will allow us to communicate more effectively, make better plans and meet goals across industries, to the benefit of our cities.

Definitions are important in today’s world – just as they’ve always been. Having a concrete, complete and detailed understanding of any given concept helps us carry that concept out to best effect.

The phrase urban ecology is no exception. The problem is, despite the critical importance of integrating our cities and worlds today, we lack any such urban ecology definition. And we really need one.

Though they’re not the best choice for all rooftops, blue roofs do offer major environmental opportunity of which we should avail ourselves. 

Question: What wears a dirty blue cape, visits Chicago more than a hundred times per year, and doesn’t give a fig about combined sewer overflows?

If you said Captain Stormwater, you are correct. The prize, well – how about being really bummed out? You know, because of the disease and toxins that pour into our streets, the urban runoff that poisons wildlife, or the overloaded city infrastructure that just can’t keep up with the amount of water sheeting off impermeable surfaces every day?

Told you, it’s a bummer.

That’s not to say we can’t do anything about it. Green roofs help solve many of these problems, transforming barren concrete and cement rooftops into vibrant oases that absorb and filter stormwater, lessening its load considerably.

Green roofs represent a significant upfront cost outlay, though, and some people aren’t willing to wait for the ROI that accrues over time. In that case, a blue roof might just do the trick. Let’s tackle what that is, why it’s beneficial, whether it’s the best solution for your rooftop, and what we can expect from blue roofs in future.

Stormwater management is a critical need in our cities and rural areas today, but to make our methods truly effective, we need to understand best practices.

To you, a sudden rainstorm is a nuisance. Your husband has the car today, so you’re walking to the L. You forgot your umbrella. Your presentation is getting wet.

Bummer.

Yet the billions of gallons that rain and snow down on cities like Chicago every year are far more than a personal inconvenience. They take a major toll, overrunning our sewers, sending pollution and disease into waterways, and ruining both metropolitan and rural areas.

The problem is, we tend to think of “saving the environment” as pertaining to the wilds, or at least to wetlands and parks – both inside and outside the city.

In truth, the urban environment is important as well. It’s where humans live (duh), and if we don’t take careful steps to make cities healthy, we’re hurting not only the world, but ourselves.

So how does stormwater come into the picture? Today, we’ll examine exactly what stormwater is and what we can do to manage it more effectively using long-term solutions rather than temporary measures.

In other words, using stormwater management best practices.

With a 5,000-foot garden on a 1/4-acre lot and a business dedicated to "compassionate" native gardening, Benjamin Vogt is a front-runner IN multiple areas, including sustainable design, native gardening and ecology.

Native gardening is a thing these days. It feels like you can’t throw a stone without hitting someone’s platinum certification or wildflower patch, and plenty of nurseries cater partially or exclusively to the cause.

While the buzz surrounding native gardening makes it seem like a widespread phenomenon, though, that’s unfortunately not the case. Nor is gardening for pollinators or taking an organic approach. While these are no longer fringe movements, neither are they completely mainstream. Even when people do care about native gardening, they sometimes promote the wrong messages in the name of stewardship.

Which is why it’s so important to have strong voices trying to change that.

Benjamin Vogt of Monarch Gardens is one such voice. In love with prairies and woodlands, promoting plants and animals, redefining the concept of native gardening … he does it all, and more.

Ecogardens was lucky enough to catch up with him recently. Let’s hear what he has to say.

While seasonal plantings are a lovely way to spruce up our urban spaces, as well as offer food and habitat to pollinator friends, we need to take a more sustainable route.

As stewards of our urban spaces, it’s up to us to ensure we take the most responsible approach to landscaping of all kinds.

Unfortunately, that’s not a duty we take very seriously when it comes to seasonal color. Our addiction to bright pansies in spring, impatiens in summer or marigolds in fall has major environmental and health costs, but the landscaping juggernaut has most people overlooking them.

Time to change that. We need a better understanding of the dangers this habit poses, just as we need better tools for creating sustainable seasonal plantings. Luckily, they do exist.
