#TRUEGREEN

By Melissa Muroff, Esq. 

A couple of years ago, the Sustainable Business Network of Philadelphia tapped Roofmeadow and a few other firms to test drive the prospect of forming an industry group to advocate on behalf of Green Stormwater Infrastructure (GSI) in the Philadelphia area.  Primary objectives included advancing the local GSI industry (read, local job creation) and fostering innovation.  The GSI Partners has evolved and is collaborating with like-minded contingents at BIA, DVGBC among others. As a result, a fierce commitment to promoting green infrastructure over grey has surfaced. #TrueGreen has become a rallying cry in these circles.  In fact, voices promoting grey infrastructure are notably silent.  So, if we all are in agreement (and that’s a big “if”) – from government to developers to designers to contractors, where is all the green infrastructure?

Consider our current paradigm: Philadelphia’s goal is to create nearly 9,000 Greened Acres.  Great start!

But if we continue down the course we are headed, our math suggests that the 9,000 Greened Acres will be comprised mostly of grey infrastructure.  Sort of sucks the wind out of your sails, doesn’t it?

Here’s what I think: Turning around this behemoth ship of the Philadelphia water infrastructure requires a total rethink, not just a regulatory tweak or the will of a few urban champions.  An increasingly vocal collective of whip-smart designers and developers are challenging our grey legacy.  In charrettes, design competitions (Soak It Up) and built developments (Ice House, RidgeFlats), innovators are demonstrating new ways to interact with rainwater and plants; they are artists at work with a living palette. This group of leaders isn’t designing and building green roofs, living walls, rain gardens, and urban tree groves just to win stormwater credits.  It’s much bigger than that.  They envision a new urban experience where concrete and glass interact dynamically with plants, habitat and moving water to create natural spaces that draw us in, soothe us and stimulate us. Places where we inherently belong.  It’s what David Waxman of MM Partners called, “the outdoor Philadelphia experience,” and this is the Philadelphia I want to live in.

And this is your call to action:

The industry’s efforts to promote, measure, and finance green infrastructure are growing and gaining momentum every day, but we need your support. Interested?  Then join us this Tuesday morning at the GSI Partners quarterly meeting!

A Trip to Emory Knoll

by Jane Winkel

It was a beautiful day for a trip to Emory Knoll. It was (still is) early spring; it was a Friday; it was sunny. I stopped for gas before driving onto I-95, and ran through a list of sedum species trying to recall the habit of each as I pumped a full tank of mid-grade. Lost in thoughts – plants, unpaid bills, directions to the nursery, I neglected to notice the defective pump for about 3 seconds too long. The auto-stop-at-full feature had ceased to function and fuel was dripping into a clear slippery puddle at my feet. I presented my credit card and my complaint to the attendant and she casually offered a complimentary car wash.

Ed Snodgrass, Emory Knoll founder has been in the business of plants for most of his life and he has written a number of books that are must reads for those interested in green roofing. His book Green Roof Plants is regularly consulted within the Roofmeadow office.

The nursery is full of plants for sale to the green roof trade, although upon approach the farm stands out because of the swath of bamboo that serves as a screen from road traffic. Dramatic, beautiful and planted with a purpose the swath is a habitat and home for many birds and critters.

Ed is developing a potting mix that mimics the porosity of green roof media, but is made from waste products (coconut husk, rice hulls and some pine bark). Plants started in this media are less resistant to rooting out into green roof media when they are transplanted from the nursery to the roof. Low embedded energy and reuse of materials that would otherwise be headed to the landfill make the mix pretty darn sustainable.

Walking through the cutting beds, which contain plants that have been started from seed, I wondered about the possibility of spreading sedum seed on roofs (an infrequent practice in the green roof biz). To achieve germination seeds must be sown on a cool misty early spring day when the conditions are just so.

The selection of Sedum album which was collected from sites around the globe, is remarkable because of the variability in color, size and shape from plant to plant. Because of this collection, Emory Knoll can provide plants with a provenance that is similar to that of a projects’ climate.

I was lucky enough to receive a Senecio jacobsenii ‘Trailing Jade’ plug and a cutting of the loveliest peach tinted Echeveria from the hothouse, which contains particular plants of uncommon beauty. In return I shared a bag of my turmeric sea salt walnuts.

If you time it right the drive is about 1.5 hours from Philadelphia, (if you time it wrong plan to spend an extra hour sitting in traffic on I-95). Once you are off the highway, expect a scenic drive through rural Maryland. In a town called Dublin, you even pass a pasture with goats and mini ponies (tiny tiny thigh high ponies!).

Emory Knoll accepts visitors by appointment. I recommend visiting the farm to see a radiant collection of plants, the Emory Knoll green roof and the adjacent 15 year old solar array.

Designing to Survive – Helping Our Native Plants Adapt to Climate Change

By Laura Hansplant, ASLA, LEED AP, Director of Design at Roofmeadow

Whether I am focusing on green roofs or ground landscapes, I cannot escape the undeniable: Climate change is making an impact. What can designers and landowners do about it?

I’m going to start with an essential distinction.

Scale matters.  The choices we make about landscapes at a regional scale matter a lot.  Our ability to conserve large natural areas – such as habitat preserves and greenway corridors – is important. These big habitats offer opportunities for native species that we just can’t replicate, ecologically, within our developed landscapes. Integrating these large-scale habitats demands a coordinated, committed effort among civic leaders, conservancy organizations, and advocacy groups – an arduous campaign well worth the effort. (Read more about how regional land conservation can be a corner stone of climate change mitigation: Ontario’s Greenbelt strategy and Carolinian Canada.)

1-scale matters

My scale, however, has a much smaller footprint – a reality that applies to most people I know. Can we impact climate change when designing a single green roof, managing a meadow, or building a cutting garden at home? As you might guess, I have a few thoughtful recommendations.

1.  Incorporate native plant communities into the places we live and work.  Just any collection of native plants will not do. Deliberately select a suite of native species that play together well in the same, umm, mulch bed.  Specifically, look to reference plant communities in your ecoregion, and in ecoregions south, for reference communities likely to adapt well to the specific geology and soils of your site.  Also consider how plants knit together in an integral, layered way, leaving less space for weeds (and less time spent managing them). Happily, pollinating insects and birds fare better when we design with a broad range of plant species. .

2.  Preserve genetic diversity.  Many plants sold in nurseries are reproduced vegetatively, which means they are genetically identical. Genetic diversity imparts resilience to extreme weather and opportunistic pests. So, to foster resilient landscapes, specify seed-propagated, straight species instead of cultivars.  Look for regional ecotypes which offer specific adaptive traits.

2-genetic diversity

3.  Leverage the geography of plant production. People are probably the biggest movers of plants around the regional and national landscape.  Often, plants have been shipped around the region, if not across the country, by the time they arrive at a project site.  In light of these logistics, leverage your plant ordering for good. Climate change dynamics are suggesting that native plant communities might not be able to migrate fast enough to keep up, but the design community can lend a hand. For more common natives, order appropriate plants from southern ecoregions and help in a small way to shift regional populations northward. (I propose this concept of a human assist to plant migration with full deference to the implications of this strategy for rare plant conservation.)

Can you distinguish the cultivar from the straight species?

Can you distinguish the cultivar from the straight species?

4.  Allow plant reproduction in designs.  We don’t often allow plants to reproduce in the landscapes around our buildings.  I think it’s time to loosen up a bit. What is the point of promoting genetic diversity, recognizing regional plant provenance, and leveraging regional production patterns if we don’t allow plants to reproduce?  Landscapes are not static; our expectations must shift to align with the way nature works and evolves.  What if we took a more adaptive approach, one that made use of (managed) change as a healthy part of our site maintenance practices?

4-plant reproduction

5.  Foster healthy soils.  Take a ‘roots up’ approach to site stewardship that promotes healthy living soils as the foundation of a low maintenance, healthy plant community.  I’m intrigued by the potential of soil transplanting (in large intact blocks, not mass grading) as a salvage and restoration technique that carries, living and intact, herbaceous plants and seedlings, seed bank, soil microorganisms, and soil structure.

6.  Green our urban environments with a new generation of green roofs and high performance stormwater Best Management Practices.  Recent advances in green infrastructure design offer a stable, healthy approach to managing rainfall while simultaneously providing a wide range of other environmental services (including carbon sequestration). Check out Philadelphia’s innovative green infrastructure program and recent design competition. Green roofs can be lightweight, relatively inexpensive, and easily implemented over large areas – think urban heat island mitigation! Alternatively, deep soil green roofs can be designed for habitat value – think meadow roofs and wetland roofs!   Both types add value to our urban environments.

Roofmeadow’s invested in Feeding Cities

By Lauren Mandel, MLA, ASLA

As Roofmeadow’s resident Rooftop Agriculture Specialist, I was delighted to attend a food security conference in Philadelphia this past week.  “Feeding Cities: Food Security in a Rapidly Urbanizing World” attracted scientists, regional planners, urban farmers, and food security experts from around the globe, resulting in robust dialogue with an international flair.  The University of Pennsylvania and Rockefeller Foundation hosted the two-day event, which showcased the organizational prowess of the Penn Institute for Urban Research, PennDesign, The Wharton School of the University of Pennsylvania, and the School of Veterinary Medicine at the University of Pennsylvania, among others.

Feeding Cities 2013

Feeding Cities 2013

Lecture and panel discussion topics addressed diverse issues that reflected the presenters’ varied backgrounds.  Topics spanned from water resource management to food supply chains to the geopolitics of urban food security.  When viewed holistically, the talks addressed a singular, underlying questions: How do we balance the competing needs of water and food security as urban populations rapidly increase?

One panel discussion that I attended examined regional planning strategies that promote peri-urban farmland protection, or protection of farmland along the rural-urban fringe, in expanding cities.  Speakers highlighted strategies from their resident countries of Canada, Scotland, China, and the US, revealing that cities in different countries are attempting to achieve the same goal through varying methods.  The conclusion?  Each city demands a unique farmland protection strategy that satisfies local geography and culture.  This is not the easiest solution in terms of developing national strategies, but the experts seemed to agree that custom solutions are more likely to catalyze favorable results.

So where does rooftop agriculture fit into this conversation?  Well, speakers from Sri Lanka and the Middle East listed this edgy type of urban food production as a strategy deployed in their regions.  Roofmeadow applauds the global promotion of rooftop agriculture, and hopes to contribute to North America’s movement in the years to come.

My Green Roof, My Classroom

By Alison Love

My name is Alison Love, and I am a student at Germantown Friends School (GFS).  Every year, my school gives eleventh graders the month of January off to participate in an internship of their choice.  The students research and set up their own projects.  For my Junior Project, I interned at Roofmeadow.  I could not have found a more warm and welcoming place to work.  Everyone at Roofmeadow was extremely friendly and encouraging, despite their busy schedules.  My days mostly consisted of working on the maintenance aspect of the business, as well as attending daily and topical meetings.  I worked with their project database, Maintenance Manuals, and Maintenance Reports.  I could see how roofs developed over time and what happened to the plants depending on the season.  I was able to learn about the roofs while simultaneously doing work.

While working at Roofmeadow, I went up on the GFS green roof with Jane Winkel for an inspection.  It was interesting and fun (despite the freezing weather) to visit the roof because I was able to apply the work I was doing in the office to a real green roof.  To evaluate the roof, we laid down a surveyor tape and recorded the position of the line.  We placed a 1.5’x1.5’ collapsible square at the beginning of the tape.  In this square, we counted the number of different species of plants and weeds.  We estimated the coverage of vegetation and evaluated the root development.  We took samples of unknown plants and uncommonly damp soil.  After inspecting and photographing the square, we repeated the process 20 feet along the tape until we reached the end of the roof.  We checked the drains and overall sun coverage of the roof. The process was precisely documented so that students can potentially repeat it in the future.  Roofmeadow and GFS are hoping to set up an ongoing relationship.

I was also able to join some of the Roofmeadow staff on a visit to the Penn State University Agricultural Analytical Services Laboratory, where Roofmeadow sends media (soil) and irrigation water samples to be tested.  We were given a tour of the lab and a greenhouse where different green roof fabrics are tested.

It was a great experience to visit the Penn State Lab and the GFS green roof as well as to be a part of the Roofmeadow office.  It was wonderful to be part of a group that is working on innovative solutions to local and global environmental challenges.  I was learning constantly about green roof construction and benefits as well as operating a small business. I loved spending January at Roofmeadow and hope to come back soon.

Roofmeadow Green Roof Stewardship is Good for Green Roofs

Contributed by Melissa Muroff

Since the construction of our first green roof in 1997, we have been wringing our hands over our green roof blind spot. Over the years, we worked hard to prove and promote our green roof exceptionalism, but this blind spot left us feeling uncomfortable. Just over two years ago, we decided to face and eradicate the blind spot.

What is this bind spot, you ask? The blind spot is the void of knowledge regarding a green roof’s health following installation and running throughout plant establishment. As a result, we have been consumed with worry over issues ranging from plant diversity, weed pressure, root development, and the impacts of extreme summer heat and prolonged periods of drought. Roofmeadow warranties last 10 to 20 years and include a plant viability guarantee; so, we fret over our blind spot with very good reason.

What was our plan to minimize our blind spot? Developing a means of collecting reliable information from our green roofs and getting that information to the Roofmeadow office for analysis in a timely matter was priority one. Paying for this stewardship commitment was priority two.

Maintenance and Stewardship of a Roofmeadow Green Roof

Roofmeadow was the first company to include an 80% plant coverage requirement at the conclusion of the two year Workmanship Warranty period in our green roof specifications. To achieve that threshold, maintenance is required. Most green roof owners accept that this maintenance is essential; therefore, all we really needed to do was beef up the reporting requirements.

Roofmeadow requires documented maintenance as a condition of the warranty. To facilitate this documentation, we craft a Roofmeadow ® Green Roof Maintenance Manual for all of our projects. The Maintenance Manual includes a Roofmeadow® Maintenance Report which is designed to be completed by the maintenance contractor in the field. A completed Roofmeadow® Maintenance Report includes (among other things) photos and a description of the health of each plant species on the roof.

If you have a penchant for programming, this is where things get exciting. With data from Maintenance Reports pouring in from green roofs all over the country, we developed an information infrastructure capable of processing and storing data in way allows us to better manage our risks and to understand precisely how our green roofs are developing. The Roofmeadow® Plant Database tracks the performance of individual plant species at each maintenance visit. We can cross-reference plant performance characteristics with regional and microclimatic conditions, green roof profiles and plant establishment methods.

Think about it. You make a gamble when developing a green roof plant palette based on text book plant characteristics because most text book information is derived from plant performance on the ground. But green roofs are established in mineralized media which is nothing like native soils, and they are exposed to extreme rooftop weather conditions. Because we couldn’t find a comprehensive repository of rooftop plant behavior, we created one of our own in order to inform our plant palettes and maintenance strategies.

Using the information collected at each maintenance visit, Roofmeadow tracks individual species behavior (including root behavior!), weed pressure, biodiversity, hours required to perform maintenance, the impact of irrigation schedules, media and irrigation water test results, drainage and wind effects.

Documentation of Root Health During a Maintenance Visit

Now, our blind spot is manageable and greatly reduced. What have we learned? Well, for the record – and I can’t overstate this – the need for green roof research is huge. (Calling all universities . . .)  Information collected through the Roofmeadow® Maintenance Management Program is helping to fill the industry-wide information void, but we hope that universities invested in green roof research will work to develop the opportunities that we see surfacing as a result of our efforts.

As we watch our green roofs grow up, we have adapted our designs, construction protocols and maintenance stewardship strategies to accommodate the following observations.

1. Foster biodiversity. An un-maintained green roof will lose biodiversity and this is not ok. A green roof supporting one or two plant species is vulnerable to climate changes, pests and media imbalances. Don’t be lulled into thinking that a diverse weed population constitutes suitable biodiversity. Remember, green roofs are extreme environments; many weeds will burn out during summer droughts or winter, leaving large patches of bare media vulnerable to wind scour.

2. Develop a passion for propagating. Expedite plant coverage by spreading cuttings and dividing large plants. Do some homework to learn which sedums are appropriate for propagation via cuttings.

3. All sedums are not created equal. The characteristics of sedum root masses vary. Generally, deep rooted sedums will weather extreme climates better but spread more slowly.

4. Make room for annuals. Although not essential, annual springtime seeding increases biodiversity, nurse-plant environments and, of course, the visual interest of the entire roofscape.

5. Know your weeds. Not all weeds are on a mission of total domination, but for those that are, an aggressive proactive weed management plan will save maintenance dollars later on. Establish maintenance protocols that limit opportunities for weed seeds to hitchhike on to the roof or spread from one roof area to the other. Really, it’s worth the extra time to be careful about this.

6. Embrace your inner chemist. The viability of a green roof depends on the media’s ability to function properly. Submit media and irrigation water samples for annual testing at an accredited laboratory. These results should inform annual fertilization strategies.

7. Take a look under the hood. Get on the roof and make sure that the root systems are thriving and drainage layers are functioning properly. Routinely check the moisture content and the temperature of the media both at the surface and below. Most plants will not survive a swampy roof for long.  Shallow, thwarted root masses signal an ecosystem vulnerable to climate extremes.

8. Appreciate the Tao of irrigation. Irrigation requires attention. The “set it and forget it” strategy can get you into trouble. Take the time to calibrate the irrigation in order to minimize water use and create a balanced ecosystem.

9. Look out for unexpected hazards. Be aware that window cleaning fluids and exhaust vent vapors can affect media and plant health. Most window cleaning solutions do not double as fabulous fertilizers. Be mindful of the materials (or creatures!) coming in contact with the green roof and proactively address problems before they create costly complications which can be difficult to remediate.

10. Lastly, enjoy your roof! A well-loved green roof is a well maintained green roof is a healthy green roof.

How many ways can you incorporate concrete pavers into a green roof? Just ask Roofmeadow’s new Landscape Architecture Department! During the past year we designed a showcase green roof for Hanover® Architectural Products, an industry leader in architectural pavers for over 40 years, at their headquarters in Hanover, PA.

With patio seating, seatwalls, and a stage area, employees are free to enjoy the amenity space at lunchtime and for events and presentations. Hanover also uses the newly-built rooftop as a tour ground for potential clients and partners. Part of the design fun involved figuring out unintended uses for Hanover’s off the shelf and custom products. These innovative approaches enhance the diversity of products that Hanover already offers.

We will certainly be tracking the progression of this project to ensure that the plants grow, mature and flourish!

A Green Roof Grows in Brooklyn

Contributed by Jane Winkel

The 9,600 sf “garden in the sky” on the Visitor Center at the Brooklyn Botanic Garden is home to a green roof comprised of perennials, grasses and bulbs. The Visitor Center and the green roof are part of the Campaign for the Next Century initiative intended to renew the hundred year old garden. The roof garden is visible from many points within the garden. Not only a visitor center, the building will be available for private events including weddings and parties. The biodivesre green roof is comprised of over 10,000 plants and is expected to attract birds and pollinators.

Roofmeadow designed the profile and the slope stabilization system for the Visitor Center green roof. The slope of the gable roof varies and includes a peak in the center giving the roof the appearance of an upside down ship. Slope stabilization is needed over roughly half of the roof area, including any area with a slope greater than 9°. Stabilization of the media is achieved through the use of “banana cleats” secured to a geo grid net.

Slope stabilization acheived with Roofmeadow Certified Materials

Weiss/Manfredi designed the building which serves as a gateway to the botanic garden. Because of the roof’s pitch, the green roof is a prominent visual element of the architecture. The green roof works to lighten the environmental footprint of the structure and to strengthen the connection between the building and the landscape.

HM White Site Architects, the landscape architect for BBG, incorporated the green roof into their site-wide stormwater management strategy which includes rain gardens and woodland bio infiltration basins. All of the site features perform aesthetic and ecological functions and, yearly, will keep thousands of gallons of stormwater on site and out of the over-taxed New York City sewer system. Stormwater that stays on site is a resource which will sustain plant life and help to limit the need for irrigation.

Remember the fall snow storm? New York Green Roofs does! The Roofmeadow Network Contractor installed the roof garden in the fall of 2011 and watched their tender newly planted roof endure the storm. Watch this charming time lapse video of the green roof construction for a view into the experience of planting a roof and a reminder of the late October blanket.

Roofmeadow Certified media was provided by SkyGarden. Roofmeadow and Sika Sarnafil (the waterproofing provider), are warranting the assembly for a period of 20 years. As a condition of the warranty New York Green Roofs is maintaining the roofscape in compliance with the Roofmeadow Maintenance Manual.
