strikes an optimistic note about the future of our cities in an era of climate change:

Indeed, the cities of the future will be garden cities. Not for aesthetics, though beauty will follow as a by-product, but for the energy savings, water management, shelter from extreme heat and precipitation, noise buffers, and perhaps most importantly the habitat and urban wildlife these plants will support. Our cities will come alive with people, plants, and creatures thriving in interdependent coexistences” (p252)

Primary author, Tom Liptan, is hoping to change the nature of urban design itself.  As a sustainable cities advocate, such change is a vision that I share.

Liptan adds yet another term to the sustainable stormwater management lexicon: landscape stormwater management. No American city has implemented more of these LSM approaches than Portland, Oregon (where they both live—as does this reviewer). Portland has roughly 7,000 green stormwater facilities in place—including a few in its downtown! They not only manage stormwater, they “conserve water and energy, reduce urban heat island effect and thermal gain in waterways, recharge groundwater supplies, create habitat and support biodiversity, buffer noise, and provide a healthier, more adaptive, more resilient infrastructure”(p18). I will add that they make a walk or bike ride more pleasant and interesting and they are cheaper and more effective than pipes as well!

I first met primary author, landscape architect, Tom Liptan, in the early 90’s when he gave a presentation for a local builders group on green roofs in Europe. He issued a call for us to start applying green roof technology in Portland. Ultimately, Liptan became the Ecoroof Technical Manager in the Sustainable Stormwater Division of the City’s Bureau of Environmental Services (BES). Today we participate together  in Portland’s Green Roof Info Thinktank (GRIT). He and I were early advocates for restoring Portland area streams—a movement that gave impetus to the practices in this book.

This book is not just about Portland and its 7,000 LSM facilities. It’s about a design philosophy that puts the water in the landscape rather than storm drains and pipes. And it uses examples of LSM design from all over the world. Although it has lots of information you’d find in a manual: site assessment, site design, construction, inspection, cost considerations, operations and maintenance—it’s style and unusual organization makes it far more interesting than most manuals or handbooks.

As a professional who has long-criticized gizmo green, I appreciate Liptan’s statement that “a good designer relies on principles of design rather than products.” He won my heart when he exhorts us to “look first to native materials and natural systems” and employ “Design with native plants first and foremost.” It’s not immediately apparent to me that many designers in Portland actually do that—so Liptan and I have a lot more exhorting to do. I’m hoping this book and my review will help.

Sustainable Stormwater Management is organized into two major sections: Landscape Stormwater Design: Water Management from a Landscape Architectural Perspective and Landscape Stormwater Management: Vegetative Approaches to Water Management. The four chapters of the first section cover guiding principles, economics, policy and politics and something of an exhortation to the landscape architecture profession that Liptan sees as the potential leaders of this movement.

It is true that landscape architects have a jealously-guarded stranglehold over specifying plants in commercial facilities in Oregon. As a streams and natural areas restoration volunteer and native plant/ecology focused tour leader, I throw up my hands about this stranglehold every time I examine a rain garden or stormwater planter facility in Portland and see mostly over-used, alien ornamental species—some of which are invasive elsewhere. And I’ve spent much time reporting deliberately planted INVASIVE species in the past.

I now advocate that only those trained (formally or informally) in ecological restoration be allowed to design Portland’s stormwater facilities. (Just like most architects get little training in urban design, most landscape architects get little training in plants before they get their credentials—though the latter seems to be a more tightly kept secret.) Liptan admits this later in the book: Addressing the engineering, architecture and landscape architecture disciplines: “Water, soil and plants as stormwater management elements are new territory and we all have a lot to learn”(p249). “Good designers are not born but educated. . .Better education for designers and city review staff can reduce the waste of money and space.” (p250) Portland would do well to reward and learn from those of us who agree with Liptan.

The far longer second section, Landscape Stormwater Management: Vegetative Approaches to Water Management, has most of the data, tables, rules of thumb and cautions that you might find in a manual. But, with its pleas for further research, rallying cries for creative approaches, page-after-page of captioned photos and its call to design with nature using native materials, this book goes beyond a manual.

Sandy Boulevard Rain Garden

Chapter 5—Water-Accepting Landscapes—is the chapter that covers Rain Gardens and Stormwater Planters, Green Streets, and Rainwater Harvesting amongst other topics. Liptan barely uses the term bioswale conceding that it is like a long rain garden. Rather he distinguishes between rain gardens with their sloped sides and planters with their vertical structural sides. Besides that there are three types of either system: 1) infiltration landscapes, 2) partial infiltration landscapes, and 3) flow-through landscapes.

Although Liptan devotes only a half page of text under the heading “Green Street” he does have ten pages with captioned photos of green streets.   The reader can find more green street commentary in his discussions of Nashville’s Deaderick Street, Seattle’s SEA Street, Ballard (Seattle) Roadside Rain Garden Project, Portland’s Tabor to the River, Halsey Green Street and Headwaters at Tryon Creek projects. In fact much of the latter half of Chapter 5 on Site Design is devoted to making green streets work better—covering such areas as site assessment, sizing, directing flows, plantings and soils, construction, plumbing, cost considerations and operations and maintenance (O&M). (Although I understand “The intent is to focus on the outcome of the approach rather than a specific type of implementation. . .,” I found this organization a bit confusing.)

I’ve long been impressed by Tom Liptan’s minimalist approach: “The ideal LSM design should never need irrigation, pruning, or fertilization.” He cautions that O&M plans must state explicitly how plantings should be managed, otherwise most landscape contractors will default to their standard approach: “Spray it, soak it, mow it, blow it away.” Ninety percent of street planters in Portland are not irrigated—resulting in huge O&M savings. (However, as a Green Street Steward in downtown Portland, last summer I was begging nearby retailers to water the downtown planters I steward so that they wouldn’t lose any more plants.)

Most of Chapter 6—Vegetative (Living) Cover of Impervious Surfaces—is devoted to what Portland

calls ecoroofs, with Liptan using the more generalized term “vegetative roofs” to appeal to a wider audience. However he moves through vegetative walls, vegetative planters, trees, and vines before returning to research on vegetative roofs and then to their design.

He is again minimalist: Simpler vegetative roof designs found in Europe are “as good or better than most North American designs.” I would be disappointed if I didn’t see the Red Cinder Ecoroof design that Liptan developed in Portland. It’s comprised of a moisture mat, soil, and sedums planted in red cinder mulch. It’s low cost, low-maintenance, self-sustaining with no irrigation and adaptable to any roof or membrane system AND it protects the roof membrane, manages stormwater and creates habitat. “The sedums with the red cinder retard colonization by other plants for many years,” maintains Liptan.   Some additional recommendations he makes for vegetative roofs: 1) some kind of mineral mulch if not red cinder—for both moisture retention and shading the soil; 2) integrate solar panels on your roof so the plants can benefit from the shade; 3) manage solar reflections on vegetation where possible—one solution is to cover dead plants with a thin layer of rock to protect the soil and perhaps allow some plants to return.

Tanner Springs Park

Tanner Springs Park doesn’t really daylight Tanner Creek, just replicates such daylighting. But the nearby nature it brings in is great for education. Image by PlanGreen.

Chapter 7 asks the reader to think about how much impervious surface we really need then moves on to discussing porous pavement, depaving and stream daylighting. Liptan sees a bright future for buried creeks to reappear in our cities proclaiming that “A daylighted stream can be the nexus for the dramatic green transformation of an entire neighborhood.” Both the daylighting and depaving movements have been led for many years by unpaid volunteers who have formed non-profits and enlisted more volunteers to get the work done. I’m glad to see Liptan exhorting design professionals to do more in this arena.

Liptan’s is a captivating vision for change in the way we design/re-design our cities. I hope more designers and advocates too will take to heart a fragment from the book that is going up on my bathroom mirror: “…the door to creativity stands open. Enter unencumbered by the boxes of conformity, and be amazed.”

Where is Toronto’s Green Waterfront in 2015?

October 10, 2015  

Native plants at Don's Edge

All I could think when I looked down at the Don River mouth was “well, they are native plants at least!” Photo by PlanGreen

In 2007 when I wrote Greening Waterfront Development: Toronto, I was highly impressed with official plans for greening Toronto’s waterfront.  Our two day tour with Greater Portland Inc, had Waterfront Revitalization on the agenda, but we didn’t get to the area that I wanted to see–the re-naturalizing of the mouth of the Don River.

So after our debriefing on Sept. 30, I rented a bike at HI Toronto  and headed towards the Waterfront Trail then east towards the Don River. I wanted to document the progress Toronto had made in their plans to transform the mouth of this highly channelized river that I had written about in my 2007 article. I soon ran out of separated bike trail and plush new development and came to a channel with a short bridge over it.  With a bit of incredulity in my voice, I asked “Is THIS the mouth of the Don River?” of the fellow who turned out to be the drawbridge operator.

Don River Mouth and Drawbridge

I had already crossed this drawbridge when it opened for a barge carrying dredge materials. Photo by PlanGreen.

He assured me that it was. Then I asked “What about the re-naturalization they were going to be doing?”  He told me that volunteers had been doing some planting in the park down the way so I headed into the  industrial area along Villers Street making a first stop at a small public pier to capture the drawbridge opening. I was crestfallen to see the mouth of the river was still in its concrete channel and brown from sediment. Active dredging was still taking place.  In fact, the drawbridge was opening for a barge carrying dredge material upriver in what is called the Keating Channel.

I'm passionate about community ecological restoration efforts, but what I saw was not at the scale that needs to happen. Photo by PlanGreen

I did find some native species and a sign corroborating what the drawbridge operator had told me. But the scale of the ecological restoration that needs to be done there came nowhere close to the scale of the earth moving and skyscraper building that is taking place nearby. In fact, it seemed to be the proverbial drop in the bucket.

I found it disappointing that any city with 180 towering cranes in its core area alone was not making equally fast progress with the ecological restoration of one of its major rivers. It leads me to ask what kind of public benefit is the City extracting from each of these developments?

Barging Dredge up the Don

I certainly hope that the planned restoration includes removal of this ramp along the Don River too. Photo by PlanGreen

Recommendations to re-naturalize the mouth of the Don River have been in existence since 1991.  According to a Wikipedia article on the Don: In 2007, the Toronto Waterfront Development Corporation (now WaterfrontToronto) held a design competition that looked at four different configurations for the mouth of the Don. The winning bid was made by Michael Van Valkenburgh Associates.[16] The environmental assessment is expected to be complete in 2008 and construction is scheduled to begin in 2010.[17]  That Environmental Assessment was only passed by the province January 26, 2015–a 7 year lag!  This was not because of the economic “recession.”  We were told that did not phase Toronto.

MVVA Plan for Re-Naturalizing Mouth of the Don

This 2007 award-winning plan by Michael Van Valkenburg associates can be found here http://www.mvvainc.com/project.php?id=60–along with many other tantalizing images.

When I reviewed the plans by Michael Van Valkenburg Associates, I was reminded that Instead of creating naturalized banks along the straight course of the existing channel connecting the Don River with the lake, as was originally suggested in the project brief, MVVA’s design keeps the Keating Channel as an urban artifact and neighborhood amenity and creates a new mouth for the river that flows logically from the upstream source, bypassing the abrupt right turn created by the channel. A large new meandering riverfront park becomes the centerpiece of a new mixed-use neighborhood.

October 12, 2015

An interesting explanation for the delay of the re-naturalization of the Don River that I was expecting to see can be found in Planning Nature and the City: Toronto’s Lower Don River and Port Lands  by Gene Desfor and Jennifer Bonnell:

. . . in the fall of 2011 Mayor Rob Ford, his brother Councillor Doug Ford, their right-wing allies, and competing development agencies, attempted to hijack current waterfront planning processes and radically alter plans for the Port Lands. Those sympathetic to Mayor Ford’s vision see these lands primarily as a way to ease budget woes by selling prime waterfront property to international developers. As the Toronto Star editorialized, “The Fords’ ludicrous vision for the future – complete with a megamall, monorail and giant Ferris wheel – was so abysmal that a tide of Torontonians rose up in protest. Most city councillors broke with the mayor’s program and quashed the takeover [of Waterfront Toronto].”31 At the time of writing [no date provided], a political solution is being sought in which Waterfront Toronto, the City, and various special purpose government organizations are working to design a compromise between Ford’s “ludicrous vision” and the plan based on the MVVA proposal.

Don Lands Map

According to Waterfront Toronto website, construction of the Lower Don Lands Plan and the Port Lands Plan is yet to come.  There is no mention of the above controversy on their site.

A Waterfront Toronto newsroom article announced that on July 14, 2015 it, along with federal, provincial and city government partners, came up with $5M to take the next steps on the proposal to naturalize the Don River:

The due diligence work being primarily undertaken by Waterfront Toronto will provide governments with additional assurance on the estimated $975 million cost of this project, which includes rerouting the Don River to the middle of the Port Lands between the Ship Channel and the Keating Channel, remediating the area’s contaminated soil, creating new parks, wetlands and resilient urban infrastructure that will remove the flooding risk, unlock a vast area for revitalization and development – including the creation of a new community called Villiers Island – and create billions of dollars of economic development opportunities.

New Precinct Map

These new precincts are estimated to bring $3.6 billion in value, 7,672 person years of employment and $346 million in tax revenues. First partners must reroute the Don River, remediate the area’s contaminated soil, and create new parks, wetlands and resilient urban infrastructure that will remove the flooding risk. Image courtesy of Waterfront Toronto

The first phase of this due diligence work is scheduled to be completed by November of this year [2015],  and “will enable government funding of the project by providing confirmation of the cost of the project, strategies to mitigate the risks associated with the project, and an implementation strategy.”

The project would be ready to start by 2017 and take approximately seven years to complete.  An independent study by PwC done for Waterfront Toronto in 2014 estimates that “the project will generate $3.6 billion in value to the Canadian economy, 7,672 person years of employment and $346 million in tax revenues to all levels of government.”

So, to answer the question my title asks, “Where is Toronto’s Green Waterfront in 2015?”–LOOK FOR IT IN 2024!  That estimate, of course, will depend upon continued economic progress–progress that seems a bit uncertain right now.

A Perspective on Riverwalks

Feb. 18, 2015

Oregon Metro has a Request For Proposals open for a Willamette Falls Riverwalk Schematic Design that has attracted attention from design firms around North America.  I must admit that I haven’t been attracted to the “riverwalk” concept as most of its purveyors ignore the need to restore any habitat.

But Willamette Falls is different.  Right at the start, prospective proposers are informed of four core values that this riverwalk partnership has established. And Healthy Habitat–riparian, shoreline and in stream–is one of them!

After trying for two weeks, I haven’t been able to get onto anybody’s team–and it’s getting to be so late in the process that my chances are waning.  I feel that with the right team, this project  could be a near perfect fit with the mission of PlanGreen.  It has creating multi-modal linkages (transit, foot, bike and car), public participation, habitat restoration, cultural and natural history interpretation–all rolled into it.

Before & after photos by JD. She says "The top photo shows the view into what was then the Southeast Federal Center in April 2004; the bottom photo, in February 2012, reflects how things have changed in eight years." I'm no fan of turfgrass, but is this what we want our rivers to look like?

I was involved in the early stages of planning another “Riverwalk” –along the Anacostia River in Washington DC.  Jacqueline Dupree’s jdland web site provides some of the best photos of what is happening with it today.  Apparently 12 of its 20 miles is now built.  I must admit that it’s a bit painful, though not unexpected, for me to see the photos.  I feared having a trail that did little for most wildlife and little for pedestrians.  I feared a trail with too little habitat and too little shade.

I’m sure I sounded like a broken record in the early Anacostia Riverwalk planning process, but at every opportunity, I called for three things–all related:

  • Habitat restoration
  • Native trees along the length of the trail to provide shade for pedestrians
    ​ [walking outside in hot humid DC summers can be​ a pretty miserable experience without shade]
  • ​Bioretention of stormwater​ utilizing native plants

Jaqueline’s photos show that I was not highly successful. However, one of The DC government’s web pages on the Riverwalk maintains:

Key design elements throughout the trail include the following:

  • Inclusion of rain gardens and bioswales
  • Installation of shared-use paths and educational signage
  • Enhancement of trail viewsheds to bring users closer to the water’s edge
  • Minimize impacts of paving on other trail infrastructure on the natural environment.

So, maybe I got one out of three–if their rain gardens and bioswales are constructed using native plants.  With regard to their fourth design element, the only “natural environment” is in the Kenilworth Gardens portion of the trail–scheduled to be completed this spring.

I wanted–and still want–to see more ecological restoration along the rest of the trail where there is little natural environment.  I hope that the design team selected for the Willamette Falls Riverwalk will put the needs of Mother Earth over their need to make a design statement.

I hope that those involved with Willamette Falls will do so well with ecological restoration that they will inspire the people of Oregon City to rid their own trees and parks of English ivy, Himalayan blackberry, clematis, and myriad other invasive species that plague Oregon City and the Portland Metro region.  I hope they will restore healthy habitat.

Downtown Portland 2035

Posted January 28, 2015; Updated February 3, 2012

These are my comments to Portland City Council on the West Quadrant Plan of the Central City 2035 Plan–which will in turn be part of the updated Comprehensive Plan.

The Implementation Actions and Timeline Matrix for the West End is wholly inadequate re: Environmental.  In fact, it has only ONE item in it:  Encourage the continued improvement and expansion of the Brewery Blocks’ district energy system!  We, in the West End deserve better! Here are my suggestions for a better one:

Implementation Actions: West End – Environment

  • EN1 Strategically install native vegetation and trees within public open spaces, including the South Park Blocks, Portland Art Museum, Portland Center for Performing Arts, Burnside “jug handles”, Portland Central Library, Trimet turnaround. PPR, PAM, Metro
  • EN2 Reduce the impacts to neighbors from I-405 noise and air pollution by installing green walls and ecoroofs on new/redeveloped buildings. Develop a program for existing buildings as well. BPS
  • EN3 Reduce the impacts to neighbors from I-405 noise and air pollution by installing street trees—especially on SW Columbia, SW Jefferson, SW 12th and on every other street where possible to achieve a tree canopy of at least 30% PBOT, BES, BPS
  • EN4 Work with ODOT to replant I-405 with dense NATIVE trees and shrubs and improve its vine coverage of canyon walls. ODOT, BES, PBOT
  • EN5 Connect Goose Hollow with the West End and Downtown by capping I-405. Potential locations include: W Burnside, SW Yamhill/Morrison, SW Salmon/Main and SW Jefferson/Columbia. The caps could support retail or open space. As capping occurs, improve the pedestrian environment (including more trees) on SW 13th and 14th Avenues to support cap access and development. BPS, ODOT, PBOT, Private
  • EN6 Landscape SW Salmon Street with native plants and trees to achieve stormwater management, wildlife habitat and active transportation facilities to better connect Washington Park to the South Park Blocks and the Willamette River and improve the quality of water discharged into the Willamette. PBOT, BES, BPS
  • EN7 Develop SW Jefferson Street as a “Green Main Street” with stormwater facilities. PBOT, BES, BPS
  • EN8 Explore opportunities for consolidating and/or redeveloping Burnside’s “jug handles” into public spaces that also absorb stormwater. PBOT, BPS
  • EN9 Incentivize modest redevelopment of existing surface parking lots into “Parking Forests” (parkingforest.org) that achieve stormwater management while awaiting redevelopment. One idea is to institute a land tax that might be reduced if the Parking Forest is installed. BES, Private
  • EN10 Explore opportunities for one or more community gardens. If such gardens are within building courtyards or rooftops, they should be available to West End residents who apply, not solely the building occupants. PPR

Some of the above suggestions build upon the Urban Design Implementation Actions.  I’ll explore a few of them in a little more depth below, starting with TREES!

Well-maintained, but forlorn and HOT in summer with no shade

Apartment building on SW 12th Ave. at Columbia needs trees! Well-maintained, but forlorn and HOT in summer with no shade.

Considering our need to adapt to climate change, the West Quad Plan should call for a far larger tree canopy–30% in the West End.  And it should show more specifics about where those trees need to go, e.g.,  SW Jefferson and Columbia west of the South Park Blocks where there are a number of older apartment buildings that currently have no shade and on SW 12th Ave. too. Trees here would give those low-income residents needed cooling in summer and also help protect all West End residents from I-405 emissions. The sidewalks on SW Jefferson and SW Columbia should be widened to accommodate these trees.  As the warming that we have set in motion takes hold over the next decade or two, every tree will become ever more precious.

These streets should also get bioretention facilities planted with a diversity of native plants to turn them into Green Streets.  I support an early idea from BPS to make SW 12th Avenue a Greenway St. and to make SW Jefferson a Green Main Street—with priority given to nature, pedestrians and bikes.

Tiny alien spruce sapling to replace 40 yr. old tree. We need a forest of NATIVE conifers instead!

Tiny alien spruce seedling to replace 40 yr. old tree.  Tell ODOT this doesn’t meet our new Tree Code!  We need a forest of NATIVE conifers along I-405 instead!

The plan should develop a program to help owners of all buildings on SW 13th and 14th Avenues install green walls to mitigate freeway emissions for their own residents and employees as well as the surrounding community.  If research here shows its effectiveness, such installation should become mandatory. See Green Walls Could Cut Street-Canyon Air Pollution.

The Plan should call for the City to work with ODOT to improve the tree and vine coverage of I-405 and adjoining streets. (Several trees have fallen in 2014.)   I-205 where a native forest is being planted could be looked at as a model.  Ultimately, the Plan should set a timeline for capping I-405 in the not too distant future.

Make at least one east-west running street a connectivity corridor for wildlife from Washington Park to the Willamette River. I have suggested SW Salmon for this street because I believe it to be the most direct route. I regularly walk it from downtown to Washington Park and bike it through downtown to Tom McCall Park on the river. I believe I was successful in getting this idea into the Plan, but I want to repeat this recommendation so that it doesn’t get removed.

Micro swales such as this one installed on the side of Portland Armory could be part of the palate for buildings in the Park Blocks.

Micro swales such as this one installed on the side of Portland Armory could be part of the palate for buildings in the Park Blocks.

The Plan should also call for re-wilding our Park Blocks in order give wildlife south-north corridor from Marquam Park to the Willamette River where the North Park Blocks join the River in the Pearl District.

The Plan should return to us the victory we had won for no parking around the inner perimeter of the Park Blocks.  The “temporary” parking there was only supposed to last as long as it took to build the Transit Mall.  The Plan should call for turning some of those reclaimed parking spaces into sponges for stormwater and habitat for wildlife.

Green walls, green roofs and rain gardens should be required for any building that occupies space in or adjacent the original Park Blocks–especially those blocks north of Director Park. This will help create a continuous corridor for wildlife along a south-north route.

WRDNotebookThe Willamette River itself needs to become more wild through our City.  The Plan needs to call for implementing the excellent technologies in the Willamette River Design Notebook.  It should make them mandatory.  And we need to bring in far more native trees, shrubs and wildflowers to Tom McCall Waterfront Park as well as other portions of the river’s shoreline.

Where the shore of the River is deeply walled, the Plan should designate areas for “fish hotels” to provide resting places for migrating fish on their journey up or down the river.

This parking lot at SW 10th & Main is one of many in downtown Portland that have no trees--creating wastelands for the residences around them.

This parking lot at SW 10th & Main is one of many in downtown Portland that have no trees–creating wastelands for the residences around them.

Yes! to the suggestions from downtown residents on the Comprehensive Plan MapApp¹ to replace surface parking lots. I suggested a way to move the speculators off their cash cows by taxing them at their development potential–see Universal Tax Abatement for Downtown Portland.

EcotrustParking

Ecotrust parking lot is enclosed on two sides by trees and mostly native shrubs and wildflowers. The surface is porous pavers. Its a delightful place to hold events, Photo: Green Hammer

Meanwhile on these sites, the Plan should require a Parking Forest (Maria Cahill’s idea for getting more trees without taking parking spaces).  I would really like to see what surface parking lots that do remain in the future take a page from Ecotrust and manage ALL stormwater onsite.  They should also be fun places to hold events. Ruth Ann Barrett has a video that could be used to popularize these strategies: Spongy Parking Lots,

Some MapApp commentators before me call for the Plan to stimulate more housing. To their voices, I would add more FAMILY housing. To bring in more families, downtown needs more reasonably priced apartments and condos and some of them need to be three bedroom–with maybe a daycare center or school on the ground floor. Cargo bike parking should also be part of these new family-friendly buildings—along with space to lock bike trailers—and okay, I’ll concede a few station wagons. . .

We DON’T need more point towers to attract wealthy investors who will only live here part time—if at all. I have long promoted density–but only along with great urban design and ecosystem services–leaving room for nature to help us out. I have come to believe that lower height limits–say 150-160′ in the West End–are necessary in order to mitigate the wind tunnel effect of tall buildings and their impacts on solar access–and to make our neighborhood more appealing to families.

¹Portlanders commenting on the update to our Comprehensive Plan are asked to put comments directly on MapApp. I hope to add some of these there too–although it looks like those of us in the Central City may be excluded.

Park City As Biodiverstiy Engine?

Park City As Biodiverstiy Engine?

June 3, 2013  Richard Louv, author of Last Child in the Woods and The Nature Principle (as well as six other books), was the keynote speaker at CNU 21, the 21st annual conference of the Congress for the New Urbanism, held this year in Salt Lake City, Utah. CNU 21’s theme was Living Community and Louv’s task was to weave the connection between family, nature and community.

Louv made his case on the disconnect between children and nature with some of the data and anecdotes from his books. Most importlay, the remedy he proposes is “A NEW KIND OF CITY”  “Cities can become engines of biodiversity,” he proclaimed.

What if CNU sponsored an effort to create a “homegrown national park” along the lines of what author and entomologist Doug Tallamy calls for in his book Bringing Nature Home? Louv asked. Tallamy suggests that if people would turn their backyards into native habitat, we could provide so many more ecosystem services to address the big problems of our time:BackyardHabSign

  • Climate change
  • The crash in biodiversity
  • The disconnect between children & nature

Louv exhorted us to embrace the New Nature Movement  using as an example Bill McDonough’s design  for a hospital in Spain. In the design, one side is a green wall; another side is solid solar panels done in the colors of a butterfly that is about to go extinct in that region; the third side is a vertical farm that will feed people in the hospital. It’s an example of a building that not only conserves energy, but also produces human energy – through the food grown, and the view of plants and more natural habitat. What’s more, this hospital takes the next step: regeneration. The hospital’s bottom floor will become a “butterfly factory” where anyone who walks into the hospital may see one of the threatened butterflies of the region land on them. The hospital staff will reach out to every school, place of worship, business, and home and say, “You can do this, too. We can bring this butterfly back.”  So this building is not only conserving energy and producing human energy through biophilic design, it is, in a sense, giving birth – by helping a species survive. Conservation is no longer enough! We must regenerate nature–bring it back into our cities! proclaimed Louv.

Louv didn’t take questions at the plenary.  Instead it was suggested that we could ask them at the book-signing table–where a long line quickly formed.  I was delighted to see that sales were brisk as Louv covers topics that he could only mention in his talk in much more detail in the books .

DSCN0925

Because this land is in the public realm, it is a great place to start the movement towards a “homegrown national park.”

The next day, the mountains surrounding Salt Lake City were calling to me, so I joined the tour to Park City’s historic main street. During the time set aside for lunch, three of us encountered a pleasant park on our walk up Main Street. I asked my two companions what they thought of Richard Louv’s talk the night before. The Gen X one said it had introduced her to the important concept of “Nature Deficit Disorder” in both children and adults and that she would look for opportunities to help overcome this disorder in her future work.  HOORAY!

The other, a CNU Board member, said he thought the speech was not very insightful and was lacking in specifics on which to  move forward.  He felt that the lack of visuals (no PowerPoint or anything else) was a real negative.  The speech simply lacked specific examples of what Louv was talking about. “I see what you mean,” I said, “but I can provide one here.”

To the surprise, if not disgruntlement, of my companions, I used a “nature principle” framework to assess the park. According to Louv, studies show that parks with the highest biodiversity are the parks from which people benefit the most psychologically. How did this park rank?

By failing to slow, cool and filter street runoff above,-the town was losing habitat value of this creek

There was a small creek running through the park, but you could see from the large storm drain in the street above that this creek could become a danger to children and pets whenever it received street runoff–because of both pollutants and flashiness. I imagined the hard rains two days earlier creating a mini flash flood through here. By failing to slow, cool and filter street runoff–perhaps in a series of lovely native plant rain gardens–the town was losing out on the habitat value that this creek could provide to many aquatic species.

Rather than these alien ornamentals, Utah’s colorful and hardy native species could provide habitat for native insects, the base of the food chain, as well as education about natural heritage

Rather than utilize some of Utah’s fabulous high desert lupines, lomatiums, paintbrush, asters, daisies, phlox and other plant species to celebrate its historic natural as well as cultural heritage, the same old over-utilized plant species we see in Anywhere USA plus turf grass graced the park. Native plants would also be far better habitat for the base of the food chain,native insects, as well.

So, utilizing the guidepost of biodiversity, Old Town Neighborhood Park would not rank very well. But, because this land is in the public realm, it is a great place to start the movement towards a “homegrown national park.”  With a diverse landscape of natives and educational signage and perhaps classes, I could imagine this park helping to transform those Park City yards that are now filled with dandelions, garlic mustard and other invasives into an engine for biodiversity. So Park City, let’s get started!

Portland: A New Kind of City – Part III, Greenways

The deadline for comments on Portland’s Draft Comprehensive Plan is May 1. I hope you will endorse this Greenways comment at http://www.portlandoregon.gov/bps/60988 before that date     –or write your own. 

Portland planners have been talking about integrating fingers of green into the city for a couple of years now.  Then they gave the concept some teeth in the Portland Plan and now the draft Portland Comprehensive Plan with  the concepts of Habitat Corridors (pp4-6 and 4-7) and Greenways (pp 6-34 [sic] and 5-35).

Tree Crew Leaders rally before each planting

I love planning, but it’s implementation that really lights my fire.  I haven’t figured out how to become a developer yet, so I plant trees with Friends of Trees. In fact, I’m a Tree Crew Leader in both its Neighborhood Tree and the Green Space Initiative planting programs.

I look forward to my Neighborhood Tree planting days with a bit of ambivalence.  I love helping neighbors get those big trees into the ground while getting to know each other better as neighbors. We also have conversations with people out in their yards or walking their dogs in the neighborhood–adding to the sense of community.  But I often cringe at the tree species selection that I am assigned to plant.  Rarely is there a native tree in my allotment of 9-12 trees–lots of Persian ironwood, Japanese snowbells, Chinese dogwoods and. . .you get the picture!  I’ve even come to celebrate when I get a Rocky Mountain Globe Maple because that’s a little closer to the Pacific Northwest.

Last Saturday, April 20, 2013, Friends of Trees had its Earthday planting on the NE Holman Greenway.  Homeowners along Holman had been offered FREE trees because their street had been designated a Greenway.  It was Earthday and  we were planting a Greenway, so I was hopeful that at last we might be planting some NATIVE street trees.  Several businesses had sent teams, so it was an opportunity to educate them.

P1080381

Part of my Friends of Trees crew planting a tree that will help transform this street.

I thought I recognized only one tree on the list as a native tree: Swamp white oak. Turns out, it’s native to the same region I am–the mid-Atlantic (and a bit further).  But it’s not native here–so, unfortunately, there were no natives.

We’ve  started to implement the Greenway concept before the Comp Plan passes. My point is, why aren’t Greenways green in more ways than bikes and stormwater. The draft Comp Plan mentions promoting multi-objective approaches. So let’s add one more objective to our Greenways. Let’s add wildlife habitat too.  My brief additions to the draft plan policy are in RED . Its already a great policy, so I did not have to change much!

Policy 5.26 Greenways. Create a citywide network of Greenways that provide distinctive and attractive pedestrian- and bike and wildlife-friendly green streets and trails that link centers, parks, schools, rivers, natural areas, and other key community destinations.

5.26.a. Strive for an integrated Greenway system that includes regional trails through natural areas and along Portland’s rivers, connected to green streets and other enhanced streets that provide connections to and through the city’s neighborhoods.

5.26.b. Prioritize multi-objective approaches that draw on and contribute to Portland’s pedestrian, bicycle, green street, wildlife corridor and parks and open space systems.  Recognize that to be multi-objective for wildlife, native plant species are required.

5.26.c Strive to re-landscape most Greenways with native plants both to better serve our native wildlife and to allow more children to experience nature where they live. Require plantings in the public right-of-way be native and strongly encourage native plantings on private property too.

The draft Plan commentary on Habitat Corridors suggests: Corridors to connect bird habitat on Mount Tablr and Clatsop Butte could be provided across 82nd Avenue and I-205 by planting large, primarily (sic) native trees, incorporating naturescaping into yards and other landscaped areas, and/or installing ecoroofs that have suitable native plants. This is an excellent suggestion but it needs to be applied more widely.

P1010952

There’s no reason this and all the bioswales along this Greenway couldn’t be planted in native plants and trees.

 

We’re already connecting Mt. Tabor to the Willamette River (Tabor to the River). Let’s connect the Willamette  River to the Columbia through North and Northeast Portland. Let’s connect Forest Park to the Willamette through Goose Hollow and Downtown and through Northwest and the Pearl.

The Greenways designated on the Comp Plan  map below (from p.4-6 and 5-34)–and a few others I would propose that are not yet on the map–are the logical places to make those connections. If we can do this, we will truly be creating a new kind of city–one that is more friendly to wildlife, to children–and to the rest of us too.

The photos I’ve used to illustrate this article are stand-ins from earlier events I photographed. I will be adding the final ones as they become available. Meanwhile, I thought it was important to publish this before the May 1 deadline on comments.

Healthy Economy, Healthy Environment: Industry and the River

Environmental Workshop Comp Plan Update at the Native American Center, Portland State University

I went to the session the Portland Bureau of Planning and Sustainability had for the environmental community last night (April 3, 2013) on the current Working Draft of the new Comprehensive Plan. This session was held at the Native American Center on the Portland State University campus at the behest of two members of the Watershed and Environmental Health Professional Expert Group (PEG): Judy Bluehorse Skelton and Claire Carder. Judy gave a tour of the student-planted and maintained green roof atop the Center and someone else led one on the other green infrastructure on the campus.

P1080740

Environmental planner, Shannon Buono, and economic development planner, Steve Kountz, presenting the dilemma between industrial expansion and environmental protection.

At the session on “Healthy Economy, Healthy Environment”, I came to the conclusion that more of us who care about the environment need to be

  1. praising manufacturers, like Toyota, who are willing to change their ways to restore the environment at their facility along the river (Please see my blog on Toyota.);
  2. pushing the City to recruit more companies like Toyota and giving them suggestions from our own reading and research;
  3. exposing industrialists in North Portland who are unwilling to work towards creating a healthy environment along with the jobs they tout;
  4. asking lots of questions about proposed tax breaks for brownfield redevelopment and coming up with acceptable solutions.
  5. supporting North Portland residents who are stewarding and restoring parks such as Pier Park   that can become part of a wildlife connectivity corridor if linked to other natural areas.

I sent planners links to two recent articles by Richard Florida and Neal Peirce exploring “The Uselessness of Tax Incentives for Economic Development”. Both were based on a New York Times in-depth series on the topic. I already got a response from planner Steve Kountz distinguishing tax breaks for land from the tax breaks for business that the NYT series was largely about.  I hope that he will put that response below in the comments.

P1080739

Image highlighting the location of most of Portland’s industrial lands–along the Willamette and Columbia Rivers.

Otherwise, we will see the continued erosion of what greenspace is left at the confluence of TWO great rivers–the Columbia and the Willamette–an area that is critically important to wildlife. Already, planners propose to take at least a portion of 800 acres of golf courses and most of West Hayden Island into industrial land. Many of us said we preferred that the City push the redevelopment of vacant brownfields first, but the difficulty Steve pointed out was cost. He encouraged us to read the City’s Brownfield Assessment report, but it seems the solutions boil down to tax incentives. Most of the group were wary about those as well.

Other solutions for wildlife that were discussed were green or ecoroofs  atop factories and other facilities and bioswales  along parking lots and roads. In its North Reach River Plan, the City has proposed the Willamette Greenway Plan be extended through the industrial corridor, but industry pushed back (see Toyota link above).

Please use this link to send the City your own comments. They are due by May 1,2013 but don’t delay until then.  Do it today!

Children and Nature Belong Downtown

March 30, 2013   This post was first  published on the Children & Nature Network Blog. It’s editor, Richard Louv, attempted to make it more interesting for his international audience with his edits. Here, I want to re-capture some of my original thoughts.

Each year at the end of August, the Oregon Symphony holds a free concert at the south end of Portland’s downtown Tom McCall Waterfront Park on the Willamette River. Families come with picnic supper, blankets and lawn chairs. I’ve noticed that the kids who are old enough for a little independence make a beeline for the wildest part of the waterfront—a shore with driftwood, rocks and boulders.

Older kids make a beeline for this remnant downtown beach during concerts and festivals.

Older kids make a beeline for this remnant beach during concerts and festivals at “The Bowl”–the only place where the Willamette River is accessible in downtown Portland.

Climbing over the tree limbs and rocks is rough going. But the kids are unfazed. That’s where they want to be.

My Portland Downtown Neighborhood Association has been talking about the need for more families in downtown Portland. Now that developers are finding financing to build again, we are seeing more proposals for apartments downtown. Members of our association would like to see some of those apartments be appropriate for families — in size, in design and in price.

Families with children who might consider moving downtown are often deterred by the lack of affordable housing and the absence of a downtown public elementary school. However, there’s another reason that families with children often avoid living downtown in America’s cities: the need for more wild in downtown to attract those families who escaped the city for the “wide open spaces” of the suburbs.

Except for “The Bowl”, most of Portland’s central city waterfront is armored with a seawall—like many river cities, with good reason. When the Willamette was at severe flood stage as it was in 1996, we had to throw up sandbags so that the first few blocks of downtown wouldn’t flood — as they did historically. The Portland Daily Journal of Commerce has some fun photos of people canoeing along Third Ave and other parts of downtown.

As a result of those seawalls, the river at normal flow appears to be about 25 feet to the surface of the water. So how do we make the riverfront more attractive to families who want to touch nature? Portland’s new Working Draft Comprehensive Plan encourages more beaches along the waterfront. One suggested policy for the Willamette River Watershed is: “Promote rehabilitation of riverbank sections that have been significantly altered because of development to create more natural riverbank conditions.”

With the intention to attract both families and fish downtown, we could do much to make “The Bowl” more natural. But to address other parts of the downtown waterfront–-and still avoid flooding–-we may need to adapt Chicago’s invention of a Fish Hotel and stairs down to this structure created out of plants to give fish resting and hiding places.

P1040400

Hundreds of children already use the downtown area known as South Park Blocks—largely on the way to the Performing Arts Center and museums. They come by bus from other neighborhoods.

Let’s look at what else downtowns, particularly Portland’s, could do to meet children’s need for wild in their lives. Why not rethink our parks and our other public spaces downtown? Portland is lucky enough to have both a linear waterfront park and the Park Blocks, an interior corridor, originally intended as a firebreak, that extend most of the length of our downtown. Could these be re-conceived as wildlife and children’s corridors?

Portland’s early founders were wise enough to leave undeveloped blocks planted with trees (mostly American elms), running from north-to-south for twelve blocks of central westside Portland. Ultimately, these blocks, planted with native species, could become part of something much larger, along the lines of Doug Tallamy’s idea for a “Homegrown National Park.

P1040457

Green (or Eco) Roofs, such as this one on Portland Central Library could be added to all buildings that occupy what is known as the Park Blocks corridor. This could help to create north-south connectivity throughout central westside Portland.

Tallamy recommends that cities and neighborhoods across the country replace alien ornamentals with native plants—and hence attract more species of native wildlife. Many existing buildings could install green roofs and green walls with native plants to attract our native insects, the base of the food chain.

Portland might also make the streets along the Park Blocks into  “green streets.”  These streets would utilize native plants and trees and porous pavement to filter storm water from the streets and sidewalks. They would prioritize the pedestrian and the bicyclist in their design and allow for a number of sidewalk cafés. Of course they would provide a lane for business deliveries by motor vehicle and bike, perhaps limited to certain hours.

Shigezo

Sidewalk cafes such as this one at SW Salmon & Park would also be encouraged in our children and wildlife corridors.

Finally, we need a contiguous green west-east corridor to connect Portland’s premier wildlife corridor, Forest Park to the river.  I nominate SW Salmon Street/Park Place, my usual path to get to Washington and Forest Park. We could give property owners incentives to turn their existing landscapes into native habitat and to green their existing roofs, walls, parking lots and driveways. We could create “Nature Play” pocket parks along the way and join this whole area into the Home-Grown National Park too. Scroll through the map I created in Google Maps  to see the entire length of the Park Blocks–North and South–and the suggested link from Washington Park to the river.

The Salmon/Park Place corridor could become a “Greenway” (a 20 mph street that prioritizes active transportation and filters stormwater) utilizing NATIVE trees, shrubs and plants and other technologies such as porous pavement. Parking could still be allowed on these streets as it protects pedestrians and helps slow the street.

In an era of cutbacks, how will we pay for a new green infrastructure that could allow our children to live downtown and have nature too? Annie Donovan who serves as Senior Policy Advisor for New Financial Instruments at the White House Council on Environmental Quality presents some ideas in her Forbes 1/22/13 article Smart Communities will Build Green Infrastructure. She writes: “For impact investors, green infrastructure is an emerging market. Investing in it will help build economically sustainable communities that are also resilient in the face of change.”

Doubtless, some of the empty-nesters who have moved into the condo buildings in central cities throughout the US would like to be impact investors in this arena. Let’s make that opportunity possible by creating the vision for our children — one that acknowledges the benefits of nature along with all the other rich amenities of our downtowns.

One last point.  Working Draft 1 of the Portland Comprehensive Plan Update could lead to a sea change in the way we redevelop cities. Children & Nature advocates would do well to take advantage of some of the most innovative parts in it, such as the focus on habitat, the “design with nature” approach, and the “greenways” concept. It’s a forward-looking document that encourages bold thinking — and not just for Portland.  Planners and advocates elsewhere can push their cities to adapt some of its best ideas as their own.

And that will be good news for children, families, community and nature.

AFTERTHOUGHTS

The images below help to further define the setting for those unfamiliar with Portland’s South Park Blocks and “lost park blocks.” I also provide an example from the Comp Plan: its definition of Greenways.

P1040399

Portland’s founders left Park Blocks, but some were lost to development. The Arlington Club in the background, sits in one of those lost Park Blocks. Admittance to this club is restricted to Portland’s 1%–the kind of people who should be able to fund the proposed green infrastructure.

 

 

 

 

 

 

 

 

P1080430

The buildings on the left side of this block sit in what was originally intended as Park Blocks. With time, they could revert back, but meanwhile, they should be made as wildlife-friendly and child-friendly as possible–via green roofs, green walls, wider sidewalks, street trees and other green street technologies.

Greenways are defined in the glossary of Working Draft 1 of the Portland Comprehensive Plan Update as: A system of accessible pedestrian- and bike-friendly green streets and trails that link neighborhood centers, parks, schools, natural areas, and other key community destinations. The city Greenways system is a prioritized subset of pedestrian and bicycle connections that makes use of opportunities for multi-objective, distinctive design approaches that draw on and contribute to Portland’s pedestrian, bicycle, green street, and parks and open space systems.
