Vision for Housing Justice – DOWNTOWN!

You can see leaves of Sylvester Sycamore in the foreground-hiding the pavement that Portland Art Museum has chosen to pave all the way to the sidewalk that smothers some of Sylvester’s roots. We will seek to follow the example of the native tribes who came before us and see the tree as our ancestor with a garden nurturing it.. We hope that First Unitarian Church (that you can partly see to the west) will get its alternative housing project done first. .

“Where there is no vision, there is no hope”                                             

George Washington Carver

I have long railed against what I call Downtown Portland’s Treeless Asphalt Deserts. Besides their daily assault on the health and well-being of downtown residents, try walking past a series of them on SW 12th  Ave or SW Main Street when it’s 105 degrees and smoky. Encouraged by my Portland State University Site Design class instructor, I re-designed one of these deserts: 935 SW Main Street—the 25,000 square foot surface parking lot owned by Portland Art Museum for the last 30+ years.  I see this proposal as one exemplary step towards solving our housing crisis in a systemic way.


HERE’S OUR VISION (written as the developer) . . .

The mixed income Etta Cooperative will be in a multi-story, multi-level building owned by the residents as a limited equity cooperative. The land will be held in trust by a community land trust, a 50-year old model for a new system of land tenure that takes land off of the private, commodity, speculative market and puts it into trust. The CLT issues 99-year leases to buildings on that land—buildings that can be privately or cooperatively owned—or rented.

It is named after Henrietta (Etta) Eliot who supported her husband (first minister of First Unitarian Church, Thomas Lamb Eliot) in the many social causes he championed for the poor and disenfranchised. They raised eight children on this spot and their legacy still lives in the activist Church one can see from the site. The site’s rich history—including its Native American history—will be celebrated throughout.

The best residential site in Portland has been kept as a downtown surface parking lot by Portland Art Museum for 30+ years

Figure 2 The best residential site in Portland has been kept as a downtown surface parking lot by Portland Art Museum for 30+ years

Since the cost of the land will be separated from the cost of the housing, shares in the units can be purchased at a very reasonable price–all the more remarkable because the Etta will sit on what is arguably the best residential site in Portland with its cultural, educational, park and transportation amenities. We’ll reach out to the many people of color organizations we support to generate participation from those populations. Through impact investing sites and media, we’ll seek to reach wealthy and middle class folks who want to put their bodies where their hearts are—by living in a racially diverse mixed-income community that demonstrates climate justice.

The land will be purchased from the Art Museum by a Portland philanthropist—akin to Sam Gary who founded Denver’s Urban Land Conservancy with a multi-million dollar donation in 2003.  WE ARE NOW LOOKING FOR THAT PERSON.

GREEN FEATURES

Elm Row apartments at SW Market & Park has, as part of its open space, a plaza that is open to the public. It is just a few block from the Etta site. It also has an eatery (SW corner) and fountains at this level. The Park Ave level has additional retail.

All Etta Cooperative’s power needs will be supplied by the renewably sourced district energy/combined heat and power plant Apple [We have yet to approach them] will build as part of its development to the immediate west of the Etta. (Its’ precursor district energy plant sits atop Whole Foods—owned by Amazon—in the Pearl).  Since we won’t need our own boilers or chillers we’ll have more space for our common areas and community center.  [Some of the common area will be open to the neighborhood–similar to Elm Row, a few blocks away.] And we’ll have more money to use other resource-conserving technologies—e.g, triple-paned windows, superinsulation and a bioreactor to treat toilet and greywater for reuse.

Our green roofs will provide garden spaces for residents—who will be encouraged to garden there–and on their balconies too.  Native trees, shrubs, vines and wildflowers within the site will create a haven for humans and pollinators. Signage at those spaces will also help teach children about nature and add to the ambience of the Green Loop at our front door.

Our heritage tree, Sylvester Sycamore, will have its own rain garden around it–rather than a parking spot paved to the edge of the sidewalk as Portland Art Museum does now. Considering our site’s current use as a parking lot, our rain garden will demonstrate mycoremediation–the use of fungi to take up pollutants.

By being a highly visible model in downtown Portland, our vision for an Etta Cooperative will help to educate people—both Portlanders and visitors—that we are not stuck with the housing system we have. As we watch the current system leave more and more people on the street, a system that treats housing as a social good will inspire others to mimic it.  Contact us to schedule a slide show or otherwise help with Etta’s progress.

We are thrilled to be part of a new group emerging in 2021–Oregon Cooperative Housing Network .

Although our idea for the Etta first emerged in 2019, we are thrilled to be part of a new group emerging in 2021–Oregon Cooperative Housing Network . This network has people with the right skills to help us achieve the above vision: Planning, designing, permitting, financing, developing. We encourage you to join!

Slow Street to Downtown Greenway

June 11, 2020, first given as oral testimony May 28, 2020

This blog calls for equity for the low-income people on the front lines of air pollution in downtown Portland. It was written as a testimony for a May 28 hearing on the re-adoption of Portland’s Central City 2035 Plan,

Honorable Mayor and Commissioners:

I’m Mary Vogel, a climate resiliency/climate justice consultant based in downtown’s West End who has been involved in Central City 2035 since its inception. So much air-time was given to neighbors who wanted height limits in the West End to be limited to 100 feet, that those of us from SW 12th Avenue didn’t get sufficient consideration of our health, safety, air quality and other resiliency concerns.

Frontline for Worst Air Quality

Residents in the low-income buildings (both subsidized and market rate)  that populate much of SW 12th   Ave. are downtown’s buffer to the worst of the air and noise pollution from I-405. And that’s some of the worst in the nation—see Figure 1.

Urban Greenway

So, I am asking you to consider a new design for SW 12th Ave from SW Montgomery to West Burnside—one that better fits the original proposal from Portland Bureau of Transportation. That proposal was to make SW 12th the Urban Greenway my neighbors and I deserve to better protect our health!

I was puzzled about what happened to that Urban Greenway–until investigative journalists Jonathan Maus of Bike Portland and Sarah Mirk of Portland Mercury explained how West End business owners and Portland Business Alliance got the project nixed.

  • Checking in on the SW 12th Avenue project  Maus explains how a letter from these scions of the Portland business community with property in the West End wrote a letter demanding a study:
      • John Underhill – Jake’s Restaurant
      • Jordan Menashe – Menashe Properties
      • Greg Goodman – City Center Parking
      • Christopher Robbins – McMenamin’s
      • Steve Roselli – Harsch Investment
      • Brian Wilson – Kalberer Companies
      • Don Singer – Singer Properties
      • Mark Edlen – Gerding Edlen
      • Alix Nathan – Mark Spencer Hotel Block
  • Businesses Protest Planned Downtown Bike Lane  “At the heart of this issue is how businesses view bikes in the central city” writes Mirk.

Both of these articles focus mostly on the bike lane, rather than the Greenway. But the Greenway would address the needs of a far broader spectrum of people. It would also contribute far more to livability and urban biodiversity.

Re-Design for Climate Justice

I want you to consider adding to CC2035’s Transportation System Plan–and to subsequent street plans–an improved version of this crude version I did on Streetmix.

The three motor vehicle travel lanes would be necked down to a single “Sharrow” for motorized and non-motorized vehicles.  I keep parking lanes on both sides of the street  to help the churches and businesses losing parking when the surface parking lots that dominate the street are re-developed. Planting strips are my stand in for stormwater planter basins that will filter stormwater using native plants. Some, but not all, parklets could be “Street Seats” (a PBOT program) for restaurants. In any case, they would only take up part of each block. The rest of the space would be devoted to stormwater planters, bike corrals, and bike or scooter share facilities. New buildings would vary in height up to 15 stories+. Where a curb cut for a loading dock or garage or underground utilities take up a tree space, green walls will be required up the first 10 stories of the building. All of this would contribute to renewed health–for residents, for businesses and for the environment.

My plan assumes that you will keep the ecoroof requirement in CC 2035 that I myself and others worked so hard to get into that policy. One of my advocacy groups put out a distress call that you may be planning to eliminate it.

In the name of climate justice and equity, I’m asking you to put the SW 12th Avenue Urban Greenway back into CC 2035. Please bring it back to protect those of us on the frontline of pollution. THANK YOU!

Slow Street/Safe Street

We realize full design and implementation may take awhile.  So, please make SW 12th a Slow Street/Safe Street by necking it down to one lane throughout its length–along the lines of the image above. One lane has been done many times in the past six years for two-block segments due to construction. There has been little to no impact on motor vehicle traffic.  A SLOW STREET now will make a great Tactical Urbanism approach to ultimately achieving the URBAN GREENWAY that SW 12th Avenue residents deserve.

Toward Implementation of Green Infrastructure in Japan

Jan. 22, 2018

In this presentation I review the paper “Toward Implementation of Green Infrastructure in Japan Through the Examination of the City of Portland’s Green Infrastructure Projects” by Takanori Fukuoka and Sadahisa Kato. I add to the authors’ three recommendations with three recommendations of my own based upon my knowledge of Portland’s green infrastructure. The paper was originally published in the Journal of the Japanese Institute of Landscape Architecture.

Dr. Vivek Shandas and I received an email from Sadahisa Kato that read: “Tak and I are in the center of the Japanese GI movement. We’ve been trying hard to connect academics, industry people (developers), and policy makers. We are seeing more and more public symposiums on GI. We’ve also published the first comprehensive GI book, filled with case studies– together with 40 authors.

Fukuoka and Kato first set the historical context by examining some of the federal and local events that led Portland to undertake such a wide-ranging green infrastructure program. The history included the federal Clean Water Act of 1972, the development of US Environmental Protection Agency’s Low Impact Development program in the 90’s, and EPA’s Innovative Wet Weather Grants in 2005. At the local level, the history included the Combined Sewer Overflow lawsuit in 1991, the creation of Bureau of Environmental Services Sustainable Stormwater Division in 2002, Water Quality Friendly Streets in 2003, the Watershed Management Plan in 2006 and the Grey to Green Initiative in 2008. They do not list the National Invasive Species Act of 1973 nor the listing of various species of salmon in 1998 that were further impetus for Portland’s program.

Their Case Study Research is based upon Interviews, Discussion, Site Visits, and Categorization. Their categorization is based upon project types, project information, managed stormwater areas, implemented stormwater tools and environmental benefits from the projects.

The ten sites Fukuoka and Kato categorized based upon the previously mentioned criteria are viewable in the above list.  This is a good mix of relatively old and new facilities of various types.

The green street benefits the authors chose to emphasize are viewable above.

This is one of three photos included in the paper: a flow-through planter at the west edge of the PSU campus. The plant in the foreground (lower left corner) is Nandina (aka Heavenly bamboo). When I first returned to Portland in 2007, the City had been planting it in nearly all GS facilities. I asked them over and over again to STOP this practice as the plant is invasive from Washington, DC to Florida—and possibly soon here. I haven’t seen any recent GS plantings of Nandina by the City, so someone may have listened.

This rain garden green street facility is set back from the street in a location that had empty space because of the street configuration. Rain gardens often add a park-like quality to these leftover spaces—in addition to filtering stormwater.

This photo shows one of Portland’s earliest green roofs—located on the Multnomah County Headquarters Building. Plant selection criteria included adaptability to roof conditions, ecological function, local availability, drought tolerance, seasonal interest, aesthetics, and maintenance requirements. I hope that habitat for native species and biological diversity are part of ecological function.  Ekorufu is the Japanese spelling for Ecoroof—a word popularized by the City of Portland.

Fukuoka and Kato Recommendation One for Japan: For each planning, design, construction and management phase:  1. Use multi-departmental teams AND 2. Stress flexibility and cooperation.

Fukuoka and Kato Recommendation Two: Plan and design for: A stormwater management manual defining criteria for sustainable stormwater management for new development and redevelopment, public and private AND A series of stormwater management manuals with a wealth of illustrations and examples from Portland, with a focus on: Architecture; Construction outside of the site; and References in urban scale

I was somewhat relieved that illustrations and examples from Portland did not include PLANTS although I would have liked to see more discussion of plants in the paper

Fukuoka and Kato Recommendation Three: Actively promote: Grants for pilot projects with a focus on public facilities AND An aggressive subsidies menu which also targets private business.

I first summarize my recommendations to Japan

  1. Focus on mimicking nature, not slick design
  2. Consider focus on NATIVE PLANTS to create biodiversity
  3. Consider using fungi to capture toxins

My Recommendation #1:  To focus on mimicking nature—not slick design, stress the need for designers—both municipality-employed and consultant—to have training in: ecological restoration; native plant horticulture and perhaps even a bonus for mycoremediation –using fungi to take up toxins…

Before today when most facilities are done in-house, Portland geared its Requests for Proposals to landscape architecture and civil engineering firms rather than ecological restoration firms when it sought consultants. The private sector still does.  The City’s in-house staff does not necessarily have such training either.

My Recommendation #2: Consider More Focus on Native Plants to Create Biodiversity

While the authors mention the creation of biodiversity as a function of Green Streets, they don’t address plant species—a vital part of creating biodiversity. In another paper, Sada says “These scattered green spaces, “bits of nature,” even if they are not connected, can increase the overall habitat quality of the urban matrix.”

YES! Green Streets CAN increase the overall habitat quality of the urban matrix, but only if they are designed to do so by professionals who know ecological restoration. I’ve been fighting for years to get Portland to use only NATIVE plant species. Native plants are the base of the food chain because the larvae of many native insects need native plants to develop. Insects are in turn the base of the food chain for birds and other native wildlife. This slide of a Green Street on East Burnside does show largely native plants.

Yellow flag iris was first planted in the stormwater planters on the opposite side of the plaza from what’s shown here at South Waterfront—a private passageway, but subsidized and approved by the City of Portland. After much effort on my part over a couple of years, they were finally removed, but not before much damage was done. I recently discovered that they have volunteered in this planter across the way, so it’s still there. The sunny area in the background of the first slide is the Willamette River. With the river so close by, you can see why Iris pseudacorus has now shown up at the mouth of tributary streams like Tryon and Stevens Creeks and tributary rivers like the Clackamas and Tualatin Rivers. There it degrades fish habitat and bird nesting and rearing sites.

Portland now has Iris pseudacorus on its invasive list, BUT it lists Iris ensata as an alternative—a plant ranked as an invasive by USDA so it is NOT an appropriate alternative, even if not yet invasive in Oregon. Multiple species of Cotoneaster are listed as invasive by the California Invasive Plant Council. It seems irresponsible to approve the planting of ANY species of Cotoneaster (the plant in the foreground of the photo on the right) on a major flyway like the Willamette River.

My Recommendation 3: Consider Using Fungi to Take Up Toxins and Improve Soil

Portland Green Streets currently need their top layer of soil removed and replaced periodically to stay permeable and also so that toxins they accumulate will not kill plants. Japan might consider some pilot projects in mycoremediation—as some mushroom and fungal species can both transform the toxins captured while keeping tilth in the soil. The photo shows fungal mycelia decomposing twine made of wood fibers. Those same mycelia can do a great job of decomposing polycyclic aromatic hydrocarbons and other toxins from motor vehicles as well—even heavy metals. I have written about mycoremediation research—including Washington County, Oregon’s Clean Water Services on my blog: PlanGreen.net/blog. Look for mycoremediation blogs from May 2015 to Aug 2015.

Portland has much that is great in its green infrastructure efforts. But many of its 1900+ Green Streets could do much better at increasing habitat and biodiversity through the use of native plants–and perhaps mycoremediation. It is my hope that Japan will show us how by putting biodiversity front and center in its GI program as both preserving biodiversity and installing/protecting green infrastructure are crucial to addressing climate change—and keeping snow on these two iconic peaks. I also hope that those students in Portland viewing this video will someday take over the bureaucracy and work to change the issues this presentation points out.

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.

City Creek Center as Biodiversity Engine?

DSCN0940June 2013 – City Creek Center was started in 2003 by the real estate investment arm of the Latter Day Saints. The intent was to bring back Salt Lake City’s Main Street in a downtown that was losing out to the suburbs. It’s a mixed-use project that includes retail shops, office space and 435 condominiums and 110 apartments. No public subsidy was received so the project does not include “affordable housing.”

It’s also a green roof project in that its 90,000 square feet of plantings, courtyards, roof gardens and water features cover a 6000 space parking structure. What a waterproofing challenge!

“The things the LDS Church is doing with City Creek Center are going to be a positive boost to walkability and transit in Utah” according to “Faith in Action: Communities of Faith Bring Hope for the Planet,” a national report of the Sierra Club.  The Center brought more residents, employees, shoppers and diners to use the light rail system called TRAX.

Opening in 2012, with final touches added in 2013, this downtown revitalization project took 10 years to complete.  With development continuing throughout the crash in real estate, it was one of the only privately-funded projects of its size in the US that continued to build over the last few years. I happened to meet the Portland-based ZGF architect who was their project manager for the residential portion this week (at an event in Portland, first week of June 2013) and she confirmed how important this project was to her firm.  It also kept 2000 others employed throughout the development cycle and now employs over 7000 people.  It had about 16 million visitors in its first year of operation.

You can read more about the economic development aspects of City Creek Center elsewhere e.g., Salt Lake Tribune.  What I’m going to look at here is what role City Creek Center plays in putting Salt Lake City on the path to becoming the engine of biodiversity that Richard Louv exhorted CNU 21 attendees to work towards in our work.

DSCN0967

Although I’m not a fan of shopping centers, the creek kept me coming back day-after-day

City Creek Center was actually in the middle of my route to and from the Grand America Hotel where CNU21 was held from May 29 to June 1, 2013. Even though I’m NOT a fan of shopping centers, once I saw the creek there, I happily sauntered through it every day of my five-day stay.  It gave me a taste of what I was missing in the nearby canyons as I made my way to The Grand America each day.  The creek stimulated for me feelings of peacefulness—and a desire to get out into the real thing.

I recognized immediately the trees native to this area: Populus tremuloides – aspen; Betulae occidentalis – water birch; and Prunus virginiana – chokecherry. They were planted along a lovely creek that bubbled through boulders of native sandstone.  Below the canopy level, there were native sedges and rushes and shrubs– and a few plants I didn’t recognize as native. Tough non-native shrubs were brought in to overcome the trampling the natives were experiencing.

DSCN0966

Developers made an extraordinary effort to re-create the iconic creek that was so critical in Salt Lake City’s founding

I appreciated the fact that the developers named this center after a natural feature that used to be there—AND that they made an extraordinary attempt to re-create that natural feature in their development. The creek flows across three city blocks, and drops 37 feet in elevation from beginning to end. Some 600 boulders were brought in from an area near Park City and 627 native trees from nurseries in Oregon and Idaho.

As it meanders along pedestrian walkways and cafes, the recreated creek features three waterfalls and a fountain with 50-foot-high jets. The creek varies in width from one foot to 28 feet and from four inches to 18 inches in depth.  Some parts of the creek were stocked with Bonneville cutthroat trout and rainbow trout and those fish are now reproducing.

A 17-foot waterfall at Regent Court cascades at 2,500 gallons per minute over 14 ton Utah sandstone boulders.  The landscape is actually comprised of 13 different water features that recirculate their potable water. According to Ross Nadeau, Landscape Architect project manager, “We looked at utilizing City Creek itself and then at the de-watering water from the site, but we couldn’t make either work because of the filtration costs.”

DSCN0970

The creek serves as a draw for shoppers, employees and residents

City Creek Center received a LEED ND rating of Silver for its multiple efforts to be sustainable.  “The heart and namesake of our development is the re-creation of City Creek, which many years ago used to run through the downtown area of Salt Lake City,” said Val Fagre, former City Creek Reserve project manager—now retired. The craftsmanship put into building the creek is extraordinary.  And I can vouch that the creek serves as a draw for shoppers, employees and residents of City Creek Center. In the two times I ate at the Food Court there, I went to extra effort to sit near the creek. The Center also seems to attract plenty of young people to hang out on Friday and Saturday nights.

Nearby, City Creek Canyon has been protected from the beginning of the city’s history (over 150 years) to protect drinking water and wildlife habitat.  According to students in a class project in General Ecology at Westminster College:

GlacierLily

Glacier lilies are found along the City Creek Canyon Nature Trail

By learning the names of the native trees and shrubs that support the wildlife in City Creek Canyon along the nature trail loop, one can see which plants may be useful in backyard landscaping. Native plants introduced into the urban landscape around houses and yards help wildlife to survive in the city and help conserve water.

Based upon the students’ observations (I didn’t get there), City Creek Canyon could qualify as an engine of biodiversity.  But could City Creek Center qualify?

citycreekpark-(2)

City Creek Preserve could help City Creek Park become a true gateway to City Creek Canyon wildlife corridor–as well as give it a role in flood protection. Right now, it’s a concrete ditch (lower right). Photo courtesy of SLC Parks.

I missed the small signs that interpret the plants and fish of City Creek Center so it was not apparent to me how it was being used to influence further biodiversity–but the signage is there.  Does the experience of being in a pleasant environment lead people to go home and attempt to mimic what they saw while shopping or dining? Perhaps the center could be more proactive and run some “naturescaping” classes and host some native plant sales by local groups.  The project I would most like to see is for City Creek Preserve to work with the City’s Department of Parks and Public Lands to restore City Creek Park, to a more natural condition making it a better gateway to City Creek Canyon.  A stream buffer and wetlands could be quite important there to prevent or alleviate flooding in the future, e.g., heavy snow melt flooded State Street in 1983. The City is already undertaking some watershed restoration projects funded by Chevron as mitigation for an oil spill.  Hopefully, it won’t take such a negative event for City Creek Preserve to offer such assistance in order to increase its role as a biodiversity engine.

The boulders came from Brown’s Canyon quarry, a 100 year-old business near Park City.    Does that quarry have a biodiversity management plan (a BMP for quarries developed by World Wildlife Fund)? If not, what role should City Creek Preserve play in suggesting they start one?  Of course, such a suggestion would carry more weight before the stone was purchased.

The developers took their project through the pilot phase of LEED ND.  But did they consider Sustainable Sites, a system focused on measuring and rewarding a project that protects, restores and regenerates ecosystem services – benefits provided by natural ecosystems such as cleaning air and water, climate regulation and human health benefits.

I believe City Creek Center would score well in the “Human Health & Well-being” category.  But I’m still concerned about all of the water and power used in this engineered ecosystem. Tell us what you think below: Does City Creek Center pass muster as a biodiversity engine for Salt Lake City?  Why or why not?

 

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.

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.

Portland: A New Kind of City II

In Portland: A New Kind of City I, I argued that if Portland is to achieve some of its other policies in the Watershed Health and Environment chapter of Working Draft 1, Portland Comprehensive Plan, policies such as Biodiversity and Habitat Corridors, it is important for any policy on Vegetation to stress the importance of NATIVE vegetation–in part, because native species of insects, the base of the food chain, need native plants to survive.

I want to now draw your attention to policies under the “Design With Nature” section of the Urban Design and Development chapter–one of the sections with the greatest potential to lead to transformational design and a new kind of city.

Policy 5.45 Greening the built environment. Encourage the incorporation and preservation of large healthy trees, native trees, and other vegetation in development. 5.45.a. Prioritize integrating natural elements and systems, including trees, green spaces, and vegetated stormwater management systems, into centers. 

Change Policy 5.45 and 5.45.a. to:  5.45 Encourage the preservation of existing large healthy trees and encourage the incorporation of native trees and other native vegetation into development.  5.45.a. Prioritize integrating natural elements and systems, including native trees, natural areas, and stormwater management systems utilizing native vegetation into centers.

Invasive English ivy and Himalayan blackberry growing along the Willamette River in February this content. Green is not always “green”!

My further comments on Policy 5.45: “Greening the built environment” should make clear that green is not always “green”. We have a number of trees and vegetation that actually threaten watershed health and community livability rather than benefit it.  This policy needs to be more explicit on what is green.

I realize that with global warming, plant zones are changing. That doesn’t mean that we should be welcoming more alien ornamentals from all over the world. Rather, we might monitor the robustness of our native species and possibly look to bring in more species from areas of southern Oregon or northern California. 

Policy 5.46 Commentary: (Policies in the Working Draft have commentaries on the left pages) Habitat and wildlife‐friendly design, promotes development that integrates green infrastructure, habitat‐and bird‐friendly design, and the use of appropriate, NON-INVASIVE PLANTS (emphasis mine) for pollinators. . .

Change to:  Habitat and wildlife‐friendly design, promotes development that integrates green infrastructure, habitat‐and bird‐friendly design,and the use of native plants for pollinators and other native wildlife species.

My comments on Policy 5.46 Commentary: In Bringing Nature Home, Doug Tallamy cites numerous

scientific studies (including his own) to show that even if some of our adult native insect species can use alien ornamental plants, their larvae cannot. Insects need NATIVE plant species to procreate the web of life. Since our native insects are the base of the food chain for birds and many other species of wildlife, they need native plants too. You need to define habitat, at least in part, as native vegetation—in both the commentary and the policies.

Policy 5.46. Habitat and wildlife-friendly design. Encourage habitat and wildlife-friendly neighborhood, site, and building design.

. . . 5.46.b. Encourage the incorporation of habitat into landscaping, sustainable stormwater facilities, and other features of the built environment.

Change 5.46.b to:  In order to provide habitat, encourage the incorporation native vegetation into landscaping, sustainable stormwater facilities, and other features of the built environment.

The Nature PrincipleCov

Louv points out that all plants are not the same in their ability to support food webs.

I’ll rest my comments on Policy 5.46 with a quote from Richard Louv in his book The Nature Principle:

All plants are not the same.  Unfortunately, all plants are not equal in their ability to support food webs.  Food webs develop locally over thousands of generations, with each member of the web adapting to the particular traits of the other members of the web.

I also request that Portland add a definition of habitat in the Glossary that includes native vegetation. 

I’m really not a one horse planner.  I really care about so many other aspects of urban design and development. But I feel that it is so vitally important that Portland planners and designers recognize the importance of native vegetation in achieving the City’s  goals. Unfortunately, such recognition does not appear to be the case at present.  The landscape features along central Portland’s portion of the Willamette River are currently filled with alien ornamentals and its sustainable storm water facilities continue to be filled with them too. Portland has many LEED-rated buildings, but native plants are rare in their landscapes as well. And yet this Comprehensive Plan foresees far more landscape integrated into our built environment.  It is critical to get the policy right and work with landscape architectural professionals and their schools so that we’ll have people competent to implement the policy.

I’ll have more comments on other sections of Working Draft 1, but for now I want to go out and promote this exciting document and get YOU to comment too! Thanks for doing such a great job on so many fronts, Portland planners!

Portland: A New Kind of City I

. . . As of 2008, more people now live in cities than in the countryside, worldwide. This is a huge moment in human history. This means one of two things: either human connection to nature will continue to disintegrate, or this will lead to the beginning of a new kind of city, one with new kinds of workplaces and homes that actually connect people to nature.         Richard Louv, Leaf Litter, Winter Solstice 2012

CompPlanGuideCov

The Portland Comp Plan Working Draft 1 released in January, 2013 begins to envision that new kind of city for this “huge moment in history.” It includes a transportation network that aspires to integrate nature into neighborhoods through civic corridors, neighborhood greenways and habitat connections. By doing that it seeks to: 1) increase people’s access to the outdoors, 2) provide corridors for wildlife movement, and 3) catch and treat stormwater.Its Watershed Health and the Environment chapter encourages the protection/enhancement of natural systems and their role in promoting public health—as you might expect from a chapter with that heading. However the emphasis on “designing with nature” in both its Design and Development chapter and its Transportation chapter is what really sets this plan apart and makes it transformational. It puts Portland ahead of the curve in creating Louv’s new kind of city!

The fact that we have such wise and forward-thinking planners and advisory groups to create such a draft plan does NOT mean that the work is over, however.  The devil is in the details!  So, I hope that you will review those details, attend a community workshop or two, and add your thoughts. Below, I’m sharing some of my own comments on the Comp Plan Working Draft 1 in hopes that you will voice your support for them as well as develop your own points.

I was excited to see the draft Comp Plan promise (p,14) “encouraging building and site designs that have native plants and more permeable surfaces and mimic nature, so that pollutants stay out of rivers and streams.” Only once in the actual policies, however, is there any mention of native vegetation. And that one citation is followed by an exception big enough to let an area that could be a haven for more native wildlife—the west side of the Willamette River from the Steel to the Ross Island Bridges—stand as is: largely bereft of native vegetation.

P1080364

It’s difficult to find native plants along the west side of the Willamette River from Steel Bridge to Ross Island Bridge

Policy 4.3 Vegetation. Protect, enhance and restore native AND OTHER BENEFICIAL (emphasis mine) vegetation in riparian corridors, wetlands, floodplains and upland areas.

Change to:

Policy 4.3 Vegetation. Protect, enhance and restore native vegetation throughout the landscape.

4.3a. Riparian Corridors, Wetlands, And Floodplains:  Protect, enhance and restore native vegetation in critical wildlife areas such as riparian corridors, wetlands, and floodplains.

4.3b. Upland Areas:  Protect and enhance native and other beneficial tree species. Restore the landscape with diverse native species including trees, shrubs and wildflowers.

My further comments on Policy 4.3: Since riparian corridors, wetlands, and floodplains are the most critical areas for wildlife they are the most important to be restored to predominantly native plants.  What we plant from here on out along our rivers, streams and wetlands should be native check over here. Remove “and other beneficial” vegetation from the policy.

Chair of the Department of Entomology at the University of Delaware, Douglas Tallamy, in his book Bringing Nature Home argues that if alien species were providing as many ecosystem services in their new homes as they did where they evolved, they would support about the same number of insect species in both areas—but they do not. He states:

For an alien species to contribute to the ecosystem it has invaded, it must interact with the other species in that ecosystem in the same ways that the species it has displaced interacted. . . This contribution is most likely when species have evolved together over long periods of time.

P1060778

Tallamy’s slide show at Oregon Community Trees conference left community foresters committed to using native trees.

Upland areas could be separate. I would not argue against enhancing the lives of some non-invasive, non-native trees (such as our large old elms) via treatment. I’m not yet ready to maintain that all of the street trees the city plants should be native—only that many, many more of them should be. Tallamy keynoted an Oregon Community Trees conference last year where he made the same point I’m making–as well as a lasting impression on attendees involved with community trees. “When I talk about the value of biodiversity, he said, I am talking about a natural resource that is critical to our long-term persistence in North America.”

 The Comp Plan needs to stress the need to plant more NATIVE trees and plants in upland areas too.  See my next blog, Portland: A New Kind of City II  for further comments on Working Draft 1 of the Portland Comp Plan.
