PlanGreen’s City Council Priorities – Fossil Fuels and Housing

Jan.6, 2017

On November 9, the day after what for me was a cataclysmic election, and on most Wednesdays and Thursdays until the end of 2016, I found a haven in Portland City Council meetings.  Not only did I take solace in offering testimony myself, but cheering on the testimony of citizens as young as GRADE SCHOOL age.  Most of us–certainly the young– wanted Portland to not only continue, but increase its progressive agenda.  The last Council accomplished much in those final two months, but there is still plenty left to do.  Inspired by former mayoral candidate, Sarah Iannarone, I offer my own TO-DO list for Mayor Ted Wheeler and the new City Council.

In 2017, let’s help the City of Portland continue its leadership on climate change by addressing fossil fuels–both by reducing demand and by limiting their usage, transport and storage in Portland.  We also need to divest the city’s money in them¹.

Reducing Demand for Fossil Fuels

  • Make every neighborhood more walkable. This includes
    • Adopt strong Residential Infill/Missing Middle policy to create the population levels to support the services in each neighborhood that folks want to walk to.
    • Adopt Parking Management Policy improvements that help to manage demand–the type sought by Portlanders for Parking Reform and PBOT’s own Citywide Parking Strategy and its proposed Residential Parking Permit Program.
    • Strengthen the Central City 2035 Plan re: trees and streetscape adding to the plan wider sidewalks and street trees to make downtown streets more than car sewers for commuters. (BTW, while I appreciate the need to give more focus to East Portland, as Iannarone suggests, the West End of downtown still has a predominantly low-income population, many of whom are people of different ethnic origins and races. And many use walkers or wheelchairs.)
    • Insist on a revision of the Portland Art Museum Rothko Pavillion plan seeking to close off Madison Street plaza. Instead, focus on strengthening downtown walkability and resilience–e.g. negotiate a “Madison Walkway” between SW 11th and 12th to break up this superblock.  Oppose any other property owner proposing to make downtown less walkable rather than more walkable!
  • Since the greenest building is one that is already there, work with the Unreinforced Masonry Building owners in the West End—including the Art Museum—to do seismic upgrades so that fewer buildings need to be replaced after a seismic event. (PAM is not technically a URM, rather brick veneer; however, it was built in the 1930s and has not been seismically upgraded to today’s standards.)
  • Phase out the use of studded tires that are the #1 cause of road damage and hence asphalt resurfacing—a very intensive use of fossil fuels. [I know that this is a State issue, but Portland must add this to its Legislative Agenda–see Preserving Oregon’s Roads.

Limiting Fossil Fuel Transport and Storage 

Sierra Club and 350 PDX (I’m an active member of both) have played a leadership role here–along with my friends at Center for a Sustainable Economy.  I testified at the last Council’s hearings on the no new Fossil Fuel Facilities policy and stand ready to help defend it–and to help Portland get enabling legislation to REQUIRE seismic upgrades on existing fossil fuel storage facilities.

The Housing Crisis

  • In the absence of other immediately available options, partner with the member organizations of the Village Coalition  to find additional spots where the homeless can self-organize into “tiny house villages”. This way we’ll waste less human energy—releasing it to help in the climate change effort.
  • Ban no cause evictions and pursue other tenants’ rights policies in Mayor Wheeler’s Tenants Bill of Rights published during the campaign.
  • Support the Community Land Trust concept that seeks to take housing off the private commodity speculative market and put it into public trust.  This model gives participants security, equity and legacy in their housing.  Over 50 years ago, the founders of the CLT concept saw this as a new model for land tenure in America–not just a band-aid to the system to help the low-income.  I’d like to see the City of Portland help its own CLT, Proud Ground, revive the idea that there is a new model of housing for all incomes–one that has a tremendous body of law and practice already established.

Portland needs to nurture the budding activism of the school children and Millennials who gave testimony on a variety of climate-related issues over the past year by re-doubling on its progressive policy.  As Tavis Smiley admonishes on PBS “Keep the Faith!”

¹I hope that our efforts will inspire those in other cities–especially Millennials–to work locally to get their own cities do likewise–making those cities more sustainable and resilient too.  As much as I value Millennials’ migration to our city, I know we need them more in places where the fight may seem harder.

Mycoremediation: Testing Results In The Field

 

Jordan Weiss

August 6, 2015

When Jordan Weiss set out to use mushrooms to help clean up the soils and filter the water at the former landfill/brownfield site purchased by the Dharma Rain Zen Center (DRZC), he did so based upon the mycoremediation research of others such as Paul Stamets and his team at Fungi Perfecti.  He didn’t set up the effort as a research project.  He didn’t have funders to answer to as he volunteered his time and even many of the materials. He taught workshops that brought in the  volunteer labor from the Zen Center, the Oregon Mycological  Society and neighbors and friends.

Now, to take the project to the next level as a mycoremediation model for the Portland area, Jordan and others involved with the project, like myself, would like funding.  Funders always want  data–not just university lab data or even other people’s field data, but data from the project they are asked to fund.  I’m working with Jordan to figure out what baseline data is out there re: water quality and soils and what more data we need to collect to prove that mushrooms are removing toxins on this site and can do so throughout the Portland area.

Clean Soil to Garden Boxes

Soil testing revealed high levels of PAHs in the underlying soil so clean soil is being delivered for garden boxes–photo by PlanGreen

The Phase I Environmental Site Assessment for the DRZC site is of little help with regard to pollutants in water or stormwater. Essentially, its conclusion was: No analytical testing of shallow groundwater has been reported to ODEQ.  In the Phase II ESA, eight soil samples were tested in the area where the food garden is now.  High levels of PAHs were found in this soil, causing DRZC to build boxes and import clean soil for vegetable gardening.  The area where the raingarden is does not seem to have been tested.

Garden w/Berms

There are large berms (barely visible in the photo) at the north end of the garden where mycobags were placed on July 1, 2015–photo by PlanGreen

The best place to do future myco-remediation installations may be in the food garden area at the edges of the boxes since that soil had already been tested prior to any mycoremediation efforts, . After the mushrooms get established, DRZC and its partners could continue to test  the underlying soils for levels of PAHs.  The hypothesis is that the mushrooms and their mycelia will reduce or eliminate the PAHs.

PAHs (such as acenaphthylene’s, anthracene, benzo(g,h,i)perylene, fluorine, phenanthrene and pyrene) are listed by the EPA as possible carcinogens and maximum allowable standards are set for them.

BES Water Quality Chart

BES Water Quality Chart from Appendix A of 2008 Stormwater Management Facility Monitoring Report

We will want to do stormwater testing too.  The Portland Bureau of Environmental Services (BES) Stormwater Management Facility Monitoring Reports for both 2008 and 2010 tell us what water quality data BES monitors for in its stormwater facilities. From the chart in the Appendix of the 2008 report, we see that they monitor for oil,  grease, E. coli, metals, total phosphorous and orthophosphate phosphorous, ammonia-nitrogen and nitrate nitrogen in water.

Here’s what they test in the sediments:

BES Sediment Testing Chart

HCID/TPH is a screen to determine the presence and type of petroleum products in the soil

That HCID/TPH is a way to screen for PAHs and other petroleum products in the soil.  We do know that BES also does separate soil sampling. Some of the latest soil sampling data¹ shows that E-coli and heavy oil levels were higher than the background soil sample sites located nearby–but outside of the stormwater facilities. Metal and PAH levels found in stormwater facilities were generally similar to those found in background sample soils.  While these results show that soils in green street stormwater facilities (bioswales, raingardens) are likely taking up E-coli and heavy oil from runoff that would otherwise go down a storm drain, we hope to show that with the use of mushrooms, soil results could be cleaner than the background samples in all categories tested: E-coli, heavy oil, metals and PAHs.

Raingarden Work Party

Since toxins in surface water was not found t be a problem, the largest source of future pollutants may be from runoff from the parking area in the background of this photo–by PlanGreen

 

Since the only water sampling that revealed toxins at DRZC was the seep in the northeast corner of the site², our approach for monitoring the raingarden could start with the first rains of Fall 2015.  We would largely be monitoring for pollutants from the parking area west of the raingarden. Parking lots are well-known for contaminating stormwater with PAHs when it rains.

The Portland area is fortunate to have a second mycoremediation project underway in our region. In July 2015, I set up a meeting with Clean Water Services  Jared Kinnear and Pacific University toxicology professor Deke Gunderson to learn from their project to test mushrooms for cleaning street sweepings.  They hope to get the street sweepings–what appears to be the compost I buy in bags at Ace Hardware– to the point that it is judged safe for farmers’ fields.  They set up their project in conjunction with Fungi Perfecti which provided both the protocols and the mycelium inoculated wood chips for the research.

The project has evolved from what was originally conceived.  Because of time and labor constraints and the preliminary results, the project was modified from the original one that would have tested five species of fungi to just testing Stropharia rugoso annulata (King stropharia) and Pleurotus ostreatus (Oyster mushroom).  Then it was narrowed down again when the researchers found that the oyster mycelium stayed on the wood chips rather than spreading throughout the mixture of wood chips and street sweepings.

So they are now testing the ability of King stropharia mycelium to eliminate polycyclic aromatic hydrocarbons (PAHs) or at least reduce them to a level that they are safe to spread on farm fields.  The levels of PAHs are tested on a chromatograph at Pacific University. Since once the inoculated wood chips were added to the street sweepings, the levels of PAHs were so low that they were difficult to fully measure, the team decided to spike the experimental samples with PAHs in order to measure the effectiveness of the mushrooms.

Hailey Jongeward and Prof. Deke Gunderson

The EPA has recognized 7 PAHs as priority chemicals due to their persistence in the environment.³ The most common way to be exposed is by breathing contaminated air but exposure can also come from  eating contaminated food. While we were there we met one of Dr. Gunderson’s students ,Hailey Jongeward, who has since shared with me her PowerPoint report on the project.

“Of the 7 priority chemicals we found traces of all 7 in the starting material, increasing the importance of this project” she wrote.  Those chemicals are: acenaphthylene’s, anthracene, benzo(g,h,i)perylene, fluorine, phenanthrene and pyrene.

Hailey also shared the photos of the subject material to the right.  Boxes get different ratios of wood chips to spores so that may account for the difference in the two boxes.  Both show that the mycelium is spreading, but the lower one more than the upper one.  Hailey also told me she is working in partnership with fellow Pacific University students Jake Prevou and Natalie Kimura.

I believe that the monitoring of the Dharma Rain Zen Center project needs to take on some similar elements as the Clean Water Services project and monitor soils for reduction of PAHs.  It would also be useful to test the water flowing into and back out of the raingarden, but that may prove more difficult because it was not designed for doing such testing.  Our best bet may be one identified in the Phase II ESA: “a location south of the seep had water discharge from piping, which was traced to a stormwater surface drainage feature.”

It is exciting to be part of the initiation of a technology–or rather a protocol for utilizing an ecosystem service from the seen and unseen mysteries of the natural world.  As we enter an era of climate change, such services will become more and more critical for adapting to changes, mitigating the impacts and healing our past wounds to the earth.  I want my business, PlanGreen, to be at the forefront of utilizing the services that nature provides for free.

Mycoremediation with “Spongy Parking Lots”

Aug 2, 2015

Portland’s Old Town China Town neighborhood has an abundance of surface parking lots.  In fact, it has far too many to be a vibrant neighborhood much less an expression of the eco-city that Portland purports to be.  I’ve joined with five other professional women to try to change that.  If we can’t see these central city lots immediately redeveloped to higher and better uses that house people and businesses, we at least want to see them become better parking lots–SPONGY PARKING LOTS.

Spongy Parking Lots Video image

Image borrowed from PDX Downtowner You Tube site.

My friend, Ruth Ann Barrett coined that term and even made a video about Spongy Parking Lots to share with her neighbors in Old Town/Chinatown.  She has friends who visit from California and she’s embarrassed to show them how much we waste water here in Portland.  When it rains, the water from those parking lots heats up and captures whatever pollutants vehicles leave behind on its way to the nearest storm sewer.  The surface parking lots are paved in asphalt and are major contributors to the urban heat island effect that raises the temperature as much as 10° over areas with open land and vegetation.  In turn, the extra heat increases the energy needed to cool interior spaces, and puts an extra strain on the grid by exacerbating peak energy loads and hence carbon footprint/climate change. It also contributes to smog formation adding even more public health impacts resulting from excessive outdoor temperature.

We’ll return to all that in a moment, but I first want you to remember walking on a trail in the woods where your feet just seemed to bounce on the earth beneath them.  That’s because that soil was kept porous and, yes, spongy, by the mycelium forming a thick mat that was turning wood to soil under your feet.  Those mycelium have fruiting bodies that we call mushrooms–which may or may not be visible during your walk.

Mycelium on log

The white stuff in this photo is mycelium. It will spread throughout the log and ultimately decompose it–creating spongy soil. Photo by PlanGreen.

That mycelium looks a bit like a very dense spider web criss-crossing to create quite a network.   It gets its nutrition by decomposing the cellulose in the log.  The ability of mycelium of mushrooms in the category of “white rot fungi”  to decompose cellulose is related to their ability to decompose numerous other substances as well: bacterial toxins such as e-coli and fecal coliform as well as polycyclic aromatic hydrocarbons(PAHs).  Research also shows their ability to transform  bunker fuel oil, explosives, polychlorinated biphenyls (PCBs), and organochlorine pesticides–substances we hope we won’t find in OTCT parking lots.

Ecotrust Parking Lot

Built in 2001, the parking lot at Ecotrust is an outstanding model of a “Spongy Parking Lot”. It probably even has a few mushrooms by now. Photo by PlanGreen

We do have models for Spongy Parking Lots nearby.  My favorite is at the Jean Vollum Natural Capital Center (aka Ecotrust) in the adjacent Pearl District neighborhood.  Often on a summer day, the cars are kicked out of this pleasant parking lot for an array of fairs, festivals and farmers’ markets.  If you enlarge this photo, you will see that the lot is paved with light colored porous pavers and that those trees are planted in bioswales that also hold an array of mostly native plants.  You will see that  the parking spaces drain into those bioswales. which are about 2.5 feet deep.  Not only do the soils and plants in  the bioswales infiltrate the water from the parking lot within 24 hours, they also cool the water and filter the pollutants that come from our vehicles and pets.

BES Sediment Testing Chart

HCID-TPH is a screen to determine the presence and type of petroleum products that may exist in water or soil. Table from BES 2010 Stormwater Monitoring Report referenced below.

What could be better?  Well, Portland monitors the effectiveness of its bioswales and some of the latest soil sampling data¹ shows that E-coli and heavy oil results were variable, but levels were higher than the background soil sample sites located nearby but outside of the stormwater facilities. Metal and PAH levels found in stormwater facilities were generally similar to those found in background sample soils.  While these results show that soils in bioswales are likely taking up E-coli and heavy oil from runoff that would otherwise go down a storm drain, soil results could be CLEANER THAN THE BACKGROUND SAMPLES in all categories tested: E-coli, heavy oil, metals and PAHs.  If mycelium running through the bioswale made the soil spongier and more absorbent and if those same mycelium could help the plants thrive by “eating” more of the pollutants, then I maintain we would have an even spongier parking lot.  A spongier parking lot could better utilize and clean the water running off it into bioswales.  As its trees and plants grow better with less pollutants in its soil, the spongier parking lot will decrease the urban heat island effect even more and become an important strategy for both mitigating and adapting to climate change.

I hope you will read my previous three short blogs on mycoremediation/mycofiltration (http://plangreen.net/blog) to better understand the technology I am proposing.  I plan one more mycoremediation blog on monitoring.

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?

 

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!

Ban Studded Tires in Portland’s Legislative Agenda 2013

I’m Mary Vogel and I’m speaking on behalf of myself and my Woman Business Enterprise, PlanGreen. Thank you for this opportunity to testify on Portland’s Legislative Agenda for 2013!

As most of you know studded tires cut road life in HALF in Oregon!!!  I live in downtown Portland where my major forms of transportation are walking and biking, so I am able to see and hear the villains doing it—one click, click, click, clack, clack, clack at a time.

What I am suggesting is an additional point under the Transportation agenda on p. 36. That point is:

First, deal with a major and unnecessary cause of road wear & tear in Oregon by banning studded tires.

  • ODOT estimates that studded tires cause $40 million in damage to our roads each year.
  • During its lifespan, the average studded tire chews up ½ to ¾ ton of asphalt
  • That results in a fine dust that gets in the air, on the land and, eventually, is washed into our rivers.
  • Some of that dust also lodges in our lungs where it has an inflammatory and toxic effect
  • A Swedish study found that the toxic dust created by studded tires is 60 to 100% greater than the amount from regular tires
  • The extra damage from studded tires greatly increases our consumption of petroleum products and hence our carbon footprint
  • Modern studless snow tires are safer than studded tires in almost all driving conditions found in Oregon
  • Far snowier places like Minnesota, Wisconsin and Ontario have banned studded tires; Washington and Alaska may do so this year
  • Studded tires create unsafe conditions for all drivers by creating ruts in roads

While data show that only 10% of Oregonians west of the Cascades use studded tires, I think they all commute into downtown Portland every weekday.  It seems like every third car that passes me on my bike has them—raising the hair on the back of my neck with their aggressive sound. In the women over 50 age category, I may be one of the few who meet the level of “strong and fearless,” but I will admit that studded tires rattle my nerves and make me feel less safe. What they do to the pavement certainly makes the roads less safe for all cyclists.

So, not only do studded tires cost us a lot more in road maintenance, they cost us more in public health; they cost us more in carbon footprint; they cost us more in the livability of our cities. During a time of fiscal and climate crisis, to continue to allow studded tires is irresponsible!

Please ask the legislature to ban studded tires in Oregon!  Add First, deal with a major and unnecessary cause of road wear & tear in Oregon by banning studded tires to your points under Modernize & Enhance Transportation Funding. Or make it a separate point under the city’s Transportation agenda. But please do this today as we are long overdue!

Thank you for your time!
