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 12^thAve. 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.

Figure 2 The 3 car travel lanes would be necked down to a single “Sharrow” for motorized and non-motorized vehicles. Parking Lanes on both sides of the street would be kept to help the churches and businesses that would lose parking as the surface parking lots that dominate the street are re-developed. Planting Strips are my stand in for stormwater planters. The Parklets could also be “Street Seats” for restaurants and 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+.

Figure 2 PlanGreen’s Streetmix re-design of downtown Portland’s SW 12th Avenue–a low volume street that parallels the I 405 freeway.

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 12^th 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.

End Treeless Asphalt Deserts Downtown

Central City 2035 Key Element

Last year, as part of its Comprehensive Plan update process, Portland City Council passed CC 2035, an updated plan for the central city. The Key Elements of this plan give interested residents strong footing to address the surface parking lots in downtown’s West End as the fourth key element is: 4. Redevelopment. Encourage new development on surface parking lots and vacant lots..

Surface parking lot owners have negatively impacted the health and well-being of downtown residents for far too long. Besides the noise and air pollution that they bring to their neighbors these treeless asphalt deserts are more than 10 degrees hotter than surrounding areas. When it’s 105 degrees and smoky, walking by them for block after block is nearly unbearable–especially for the many downtown residents who use canes and walkers. Take a look at what I’m talking about–bearing in mind that this is DOWNTOWN Portland. . .

Image 7. SW 10th and Main St. looking north. Note the Museum Parking sign, the only hint that this lot is owned by Portland Art Museum although the Early Bird sign makes one think its City Center Parking. Photo by PlanGreen.

You might believe that with current real estate values, they will all be developed soon. But throughout the central city building boom in Portland, this hasn’t happened. In fact, Portland Art Museum’s lot depicted in Images 6 and 7 has been a surface parking lot for 88 years!

In August of 2017, commercial real estate consultant, Brian Owendoff explained to a Portland State University Real Estate class his opinion on why there will be little movement:

1. Land Price too high: very tough to make an apartment or office tower economically viable @ $600 SF for land cost.
2. The Inclusionary Zoning requirement reduces net operating income by 10%, more or less, making apartment development not economically viable.
3. Construction costs are very high due in large part to labor shortages.
All three result in project returns below what is acceptable for institutional investment or third party construction debt.

Some Solutions

Except for the fact that some of the owners of the lots (the Goodmans, the Schnitzers and Portland Art Museum) also have the capacity to develop them, Owendoff’s market-based explanation may help explain why we’ve seen no redevelopment of the treeless asphalt deserts during the building boom.. But we can change “the market”!!! I have long suggested as a solution to this problem: the City of Portland should TAX LAND AT A HIGHER RATE THAN BUILDINGS. By taxing land at or near its development potential, owners of land that is used at less than maximum productivity–e.g.,surface parking lots–would be paying a disproportionate amount in taxes in order to keep it that way. See Land Value Tax for Downtown Portland.

Meanwhile, we could require that surface parking lots, while they remain, take a page from Ecotrust parking lot. Owners must install trees and bioswales that manage ALL stormwater onsite. They could even become fun places to hold events.

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

Let’s demand more from downtown Portland’s surface parking lot owners. Tell City Council that it’s not fair to downtown residents and visitors that owners of surface parking lots help destroy our air and water quality–not to mention temperature and aesthetic quality–with such impunity. You can help end treeless asphalt deserts by developing a vision for what you’d like to see on one of them. Then get your vision out via mainstream and social media. Call the owner and present it to them too. Grab a space on City Council’s agenda and present your vision. And watch for my vision for the Portland Art Museum lot soon!

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.

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.

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.

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.

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.

PDX Climate Action Plan 2015 Needs Urban Design

June 24, 2015 Testimony of Mary Vogel, PlanGreen to Portland City Council

There is a great deal to like in the Portland/MultCo Climate Action Plan 2015 and I applaud it as far as it goes. But one of the things missing is attention to URBAN DESIGN not just Urban Form. It needs to include implementation actions on evaluating existing land use policies that shape urban design for impact on climate change. That mandate could be included on p. 80, Urban Form and Transportation Chapter under either Decision-Making or Planning Scenarios Evaluation.

Here’s one example! We need to change a policy that:

NW Townhouses w/short driveways and garages that dominate the sidewalk. The trees are on the wrong side of the sidewalk and will not last long in their present location.

NW Townhouses w/short driveways and garages that dominate the sidewalk. The trees are on the wrong side of the sidewalk and offer no protection or additional shade to the pedestrian. They will not last long in their present location. Cars parked in these driveways will block pedestrian passage altogether. Photo by PlanGreen

Promotes private automobile use

Leads to less community interaction

Makes our sidewalks less safe and useable for pedestrians

This NW Portland sidewalk is partially blocked by this van. Note the driveway apron that usurps 1.5 public parking spaces on the street.

Displaces on-street parking spaces that make pedestrians feel safer

Usurps public parking space

Makes sidewalks less useable by pedestrians

SW Hamilton Townhouses - No street trees

This SW neighborhood street is adjacent downtown. It has the requisite off-street parking, but no street trees or landscaping to protect residents from the freeway above–or give them incentive to walk anywhere.

Disrupts the look and feel of the neighborhood

Displaces street trees that both protect and add comfort for the pedestrian

Displaces garden space that could be used to grow food

That is the requirement for off-street parking for every new house more than 500’ from a transit stop. Please make sure that a review of this policy and other existing policies is part of the Climate Action Plan. That will greatly strengthen the plan!

I’m adding a couple of examples that were not in my original testimony in order to show both the worst and best of Portland’s central city urban design with regard to parking.

NW 24th Ave Garages - Abominable Streetscape

I know you’re thinking this is the BACK of the property but its the FRONT on a street in one of the densest neighborhoods in Portland, OR–NW 24th Ave. Similar streetscapes are not uncommon in NW Portland.

Even Portland’s numerous graffiti artists don’t seem to find these garage doors compelling places for their art–even though the doors front a street in one of the densest and most popular neighborhoods in Portland.

Most pedestrians don’t find this wasteland a compelling place to be either. In fact, they cross the street in order to avoid them. How does such awful urban design continue to exist in one of the most popular neighborhoods in Portland?

NW Pettygrove Condo Garage with single curb-cut

This NW Pettygrove condo building w/garage has a single curb-cut and is an example of how off-street residential parking should be handled–if it is necessary at all.

Okay, we can keep some off-street parking. In really popular neighborhoods that folks from the suburbs flock to on evenings and weekends, residents with cars can really benefit from off-street parking. This 12 unit condo building with it’s single driveway and garage exists immediately adjacent another abomination like the one above at NW 23rd & Pettygrove in Portland. This building is an example of how off-street parking should be done–if it is done at all.

Let me know your thoughts! I will pass them on to Portland policymakers and planners.

Gretchen Kafoury Memorial Street Trees Proposal

I’m happy to announce that the Urban Greenspaces Institute will be the Fund’s fiscal sponsor. Go to https://www.urbangreenspaces.org/support-our-work and put “Gretchen Fund” in the comment box.

March 15, 2015 – Portland, Oregon

Gretchen Kafoury, one of my heroine’s and neighbors here in downtown Portland, died Friday, March 13, 2015 at the age of 72. Two weeks earlier she had testified before Portland City Council on the need to get more affordable housing into South Waterfront, part of an Urban Renewal Area that started while she was in office. I, for one, expected many more years of her deep wisdom and boundless activism.

Treeless SW Columbia St. side of Gretchen Kafoury Commons, built by Housing Authority of Portland (now Home Forward) in 2000.

I am proposing Gretchen Kafoury Memorial Street Trees on SW Columbia Street–starting with the building that bears her name at SW 13th Ave. and Columbia. Gretchen Kafoury Commons has no trees on the Columbia St. side. Street trees here could block for its residents the view of !-405–and maybe some of its air and noise pollution too. They could also calm the traffic on the all too wide SW Columbia Street.

I propose to set up a memorial fund controlled by the Kafoury family or their designee. That fund would work with Portland Urban Forestry and its Bureaus of Transportation and Environmental Services and Home Forward to do the necessary infrastructure work to put in the street trees.

SW Columbia residences between SW 11th & 12th Avenues that need memorial trees

Depending upon the amount of money the fund is able to raise, it would move eastward on SW Columbia to install street trees in front of other buildings along the street that house low-income people.

Says Jeff Speck in his book Walkable City:. . . Often the first item in the budget to be cut, street trees are key to pedestrian comfort and urban livablity in so many ways. In addition to offering shade, they reduce ambient temperatures in hot weather, absorb rainwater and tailpipe emissions, provide UV protection, and limit the effects of wind. Trees also slow cars and improve the sense of enclosure by “necking down” the street space with their canopies. Speck points to a study of street trees in Portland that found that the presence of healthy street trees likely adds $15.3 million to annual property tax revenues–a 12 to 1 payoff on what Portland spends for tree planting and maintenance.

NW corner of SW Columbia & 12th Ave. low-income residence that needs memorial trees.

NE corner SW Columbia & 12th Ave low-income residence that needs memorial trees

NE Corner SW Columbia & 12th Ave needs memorial trees

That data makes Portland sound progressive with regard to street trees, but these photos hardly make Portland seem like the eco-city it advertizes to the world. After all, these buildings are NOT in some recently annexed part of the city that has not been brought up to standards. Rather they are in the residential part of the oldest part of our city–DOWNTOWN.

SW Columbia and SW Jefferson are part of Portland’s move towards one-way couplets that, back in the 70s, turned downtown streets into car sewers for suburban commuters to get to their jobs and back out again quickly. Everything was done for the convenience of the suburban commuter. Little thought was given to those who didn’t have the means to move out.

Now, the tide has turned and we need to narrow overly wide streets and widen too narrow sidewalks–AND PLANT TREES.. As more and more people are interested in living downtown, cranes are going up on many streets, closing all but one lane of streets that are two to three traffic lanes wide. Somehow, commuters make do. For example, drivers leaving downtown are now getting by on one lane on SW Jefferson as lanes are closed for construction between SW 11th and SW 12th Avenues (and also on SW 12th)–making me think that we could re-configure this roadway and that of its couplet street SW Columbia to accommodate wider sidewalks, street trees, green street (bioretention) facilities and a bike lane. Let’s make it happen!

Addendum 3-25-15

While wider sidewalks with street trees on SW Columbia and Jefferson would be my ideal, I had to re-think my vision last week after talking with Andrew Haliburton, PE, at KPFF who generously donated his time to estimate costs based upon previous projects. Andrew said that to widen the sidewalk would likely cost on the order of $180,000–and that’s just for one side of the street! (Do you ever wonder where the term “Highway Robbery” came from?) So, in order to accomplish this project in the next year or so, the best option seems to be to install the trees on the current sidewalk. More recently, Cevero Gonzalez from PBOT told me that in order to widen the sidewalk, the City would have to move a water main and that would take millions. We should all be asking why, when TriMet dug up the streets to put in bus pads a couple years ago, that didn’t trigger the water main move. It seems that its only needed for wider sidewalks!!!

The Mexican Consulate at SW 12th & Jefferson added four street trees to the Jefferson St. side in late 2010. They make a great addition to the street!

The Mexican Consulate at SW 12th & Jefferson seems to have added trees on SW Jefferson in 2010 when it made other improvements to its property. SW Jefferson has sidewalks of similar width as SW Columbia in the blocks in question. Already, the consulate’s trees are making a world of difference in both the pedestrian experience and the visitor/occupant experience. I expect that the money for both the sidewalk removal and street tree–about $1,000 per tree according to Andrew–will be privately raised.

Addendum April 12, 2015 – After three intense weeks of work and some nail-biting, it looks like it is, in fact, possible to plant at least one tree in front of Gretchen Kafoury Commons on the SW Columbia side within the current narrow sidewalk. First, I had to check with utility companies to assure that a tree would not interfere with their underground infrastructure. Comcast (I think) and NW Natural painted their response on the street, Century Link emailed and Portland Water Bureau called. I called Comcast specifically to verify with them as that was the utility line Portland Urban Forestry’s Rick Faber had mentioned as a potential problem. And they verified good to go!

Rick Faber had already confirmed two spots in front of New Avenues for Youth, a non-profit next door to Gretchen Kafoury Commons. I talked with Sean Suib, Executive Director there. He said he is happy to seek the cooperation of his board. And he expects to cooperate on the paperwork when the time comes.

Tomorrow I meet with Stephen Kafoury–hopefully about setting up the fund. Then it will take some folks who are really great at social media and marketing to get word out there. There certainly was an impressive turnout at the memorial service on April 4. I’m hoping to reach everyone who came–and more.

April 13, 2015 – I’m happy to announce that the Urban Greenspaces Institute will be the Fund’s fiscal sponsor. Go to https://www.urbangreenspaces.org/support-our-work and put “Gretchen Fund” in the comment box. I also hope that you will join Gretchen Kafoury Memorial Street Trees on Facebook.

June 12, 2015 – As a low-income business owner who has spent well over a month of pro bono work developing the Gretchen Kafoury Memorial Street Trees Fund with the encouragement of the Kafoury family, I was both delighted with the State of the County speech today at City Club Friday Forum and depressed that I was not able to get my effort to create this fund any attention. This would have been the perfect venue to raise the measly $3500 we need to plant trees in front of the low income housing in downtown Portland bearing Gretchen’s name. I fault myself especially. Instead of asking permission, I should have used a Gretchen strategy: Don’t bother with permission, just get up and make your announcement in the Q&A session before they can stop you! You can ask forgiveness afterward.

PLEASE CONTRIBUTE to the fund to make a green buffer against the air and noise pollution from I-405. Residents of Gretchen Kafoury Commons also need the slower traffic and more pleasant walking experience that street trees bring.

July 14, 2015 – There are many more buildings housing low-income people downtown that need street trees. I’ll post a few more, but feel free to post your own too. Dowtown is everyone’s neighborhood! Let’s make this into a tactical urbanism project and get something done.

The Carmelita overlooks I-405 Freeway and the too wide Jefferson St.

Chaucer Court and adjacent parking lot have no street trees. Many residents sit outside on SW 10th Ave.

The Pinecone on SW 11th Ave. has no street trees though it does have some nice cedars on the north end of the building.

Ongford on SW 11th has no trees.

11th Ave Lofts on SW Columbia has no trees.

Downtown Portland 2035

Posted January 28, 2015; Updated February 3, 2012

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

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

Implementation Actions: West End – Environment

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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