Brownfields to Veggies

by Jason King

The Emerson Street Garden was featured in a recent Portland Mercury  article “Gone to Seed: County Turns Empty, Foreclosed Lots into Urban Gardens” mentioning Multnomah County’s program ‘County Digs‘ which provides a mechanism for “giving away tax-foreclosed property to qualified organizations for use as urban gardens by governments, non-profits and religious organizations”

Joanne Green and Groundwork Portland's Cassie Cohen at the new Emerson Street Garden formerly home to Green's house.

The article, by Sarah Mink, offers some insight into the potential of vacant urban properties to be ‘remade’ as productive space.

SCATTERED AROUND Multnomah County are 384 vacant lots that stick out like little scars of a lousy economy. For years, the county has been trying to figure out what to do with these lots—empty land seized through property tax foreclosure. But now the county has finally hit on a new idea to bring life to the abandoned lots: turning them into urban gardens.

Joanne Green pointed to the freshly planted seeds that occupy one corner of the Northeast Portland vacant lot where her home once stood. Green lived in the house at 800 NE Emerson from the mid-1970s to the early ’80s, but after she moved, the house hit some hard times: It burned down and its owner stopped paying property taxes.

After entering property tax foreclosure, Multnomah County eventually took over the derelict patch and, under the new County Digs program, donated it tax free to nonprofit Oregon Sustainable Agriculture Land Trust (OSALT) who let Groundwork Portland turn it into a garden.

The vacant lots that County Digs is turning into foreclosure gardens aren’t properties caught up in the national foreclosure crisis—there are no banks with bad loans or mortgage defaults directly involved. Instead, these vacant lots are green spaces whose owners haven’t paid property tax in six years or more.

The properties could potentially be sold off to developers. But most are oddly shaped or poorly located strips leftover after the county either sold off or gave away more desirable properties to county offices, government entities, or affordable-housing groups. The smallest is a 62-square-foot triangle running along SW Hewett; another is a 566-square-foot strip bordering 12 homes along NE Beech and Failing that remained vacant because of a state mapping error. The largest is a 16,000-square-foot railroad spur on NE 87th.

Since 2005, Multnomah County has donated three plots, all in North and Northeast Portland, to the nonprofit OSALT to turn into gardens. The nonprofit gets the land for free, under the condition that it will always be used for agriculture. This month, the county is kicking the program into full swing, opening up 16 new properties that nonprofits can apply to start farming.

Someday soon, these tax foreclosures could be coming up roses.

Green and her neighbors planted their little garden, lined with hay bales and covered in a plastic tarp to keep off frost, this past summer. The fledgling Emerson Street Garden is part of a citywide Groundwork initiative to transform unused land into neighborhood resources. A team of Blazers Boys and Girls Club kids helped plant seeds last summer in the garden, after volunteers had stripped off the topsoil, which was contaminated with lead.

Now, plastic knives stuck into the soil read “potatoes” and “carrots”—Green even planted a cute little kale next to the garden water spout. “For the slugs,” she says.

“There was good times and bad times here, but I think the garden will be an improvement,” says Green.

CDRC Plantings

by Jason King

The final stage, installation of the sedum cuttings,  has gone in for the OHSU CDRC project, providing instant greening and transforming a bleak rooftop of pavers into the beginnings of a lush and functional vegetated roof.  A few odds and ends to complete, but for the most part ready for upcoming winter rain.  A few pics of the initial install of the vegetation, which should root in quickly and begin to fill in nicely.  This shot shows the Level 4 roof from the stairway.

And Level 4 from atop the penthouse.

PDX Greenmap (Beta Version)

by Jason King

I’ve been experimenting with simple online tools to create informative mapping applications to access information about Sustainable Sites throughout a particular area.  As a side project for information and tours, I have collected and worked with Google Earth and Google Maps for plotting points and doing simple displays, but I wanted something a bit more robust to give users and added level of information and interactivity.  Inspired by a former project of mine, using the Greenmap system, this beta version is called PDX Greenmap, a more focused map of sites in the Portland-Metro Region that are focused on innovative strategies for ecological landscape architecture.

As you can see from the beginning interface, there is a hierarchy of sites which are plotted using color-coded icons.  These cover some generalized categories including:

  • Ecological Restoration
  • Information + Education
  • Green Streets
  • Permeable Paving
  • Rain Gardens + Swales
  • Stormwater Art
  • Urban Agriculture
  • Vegitecture
  • Wildlife Habitat.

A closeup shows the icons in context, in this case for The Headwaters at Tryon Creek, as site that includes many different strategies in a smaller area.

The map also gives options for background maps, including my favorite ‘Terrain’ (seen in a closeup of downtown below).

Further scaling and map layers allows users to zoom in and change background display (including aerial photos) and to open up additional detail allowing integration of data to provide links, additional information, address, contacts, and geolocation information.

There is also the ability to create hybrid maps (overlaying streets information with aerials) for easier navigation.  The display pop-ups can be customized as well to include project photographs and other information as available.  (As I mentioned it is a beta, so those visiting the site will only find this test entry with full info for now).

Further zooming capability, matched with aerial photography, connects to interesting aspect of the ecological urbanism, including aggregations of projects such as the South Waterfront green roofs above, or a closer look at a four-block area of the Pearl District below, showing views of a number of different, but interconnected through proximity, examples of rooftop greening – including Lovejoy Block 1, The Asa Townhomes, The Wyatt, and Machineworks.  The aerial aspects also give views not normally accessible to city dwellers, showing some of the green above ground that is often missed.  More information will be embedded to show publically-accessible sites that people can visit to learn more.

The interface is ok, but could use some work for additional usability and display of information.  The goal is not to focus on issues of proprietary knowledge, but make this an open-source platform that can act as a resource for collecting information, leading those interested to model projects, and increase the visibility of the landscape architecture profession in the region.   I’d definitely be interested in 1) what other tools offer customization of mapping data with low cost and little technical programming knowledge, and 2) for those locally-based, who would be interested in working on the data and gathering more sites to provide a clear picture of the Portland areas rich legacy of innovative sustainable landscape architecture.

Kick the tires and let me know what you think.

Asante Court Park – Initial Plantings

by Jason King

Work on the second phase of Asante Court, a medical office park in Medford developed by Asante Health System, was recently installed, focusing on the small park area that is the cornerstone of the common open space amenities for future site tenants.  The design  fit low-maintenance plantings of sedges, rushes, and other native species within a network of landscaped areas that were already installed throughout the park.  This challenge of blending old and new, once established, will provide a rich tapestry of colors and textures.  The impetus for this concept was replacement for what was originally planned to be turf, and to connect the park landscaping to the adjacent wetland areas – showing Asante’s visible commitment to sustainable design principles

Landscape installation, as well as pads for future benches were implemented by Natural Systems Landscape from Medford.  The pads used an innovative product, Gravel-Lok to bind the aggregate while still maintaining permeability and providing an accessible surface.  The technology also offers the ability to use a range of different aggregate types for limitless possibilities.

The first phase (completed in 2009) was development of wetland mitigation along the linear corridors that surrounds the park.  This area mitigation was necessary due to construction of a crossing roadway bridge to connect the north and south sections of the property.   Future phases will incorporate common area plantings that will provide a transition from building sites to the wetland (seem below), blending development areas, to the right of the sidewalk, to the more natural landscape system of the linear wetland to the left.

This will continue through larger patch of remnant wetland landscape, with new landscaping wrapping and framing the already stunning natural amenity – augmenting and protecting the existing beauty of the existing ecological system.

The final phase (currently finishing design) involves the implementation of a new outfall for an intermittent stormwater drainage that exists on the site.  The open channel will be rerouted into a subsurface pipe that will daylight in a outfall feature that will dissipate flows while providing an amenity for the site.   Look for some concept plans soon on this latest phase, which is slated for construction in early 2011.

Credits for the project include the great folks at Asante Health System, landscape installation by Natural Systems Landscape (Medford), wetland mitigation by Schott & Associates (Aurora), and civil engineering from CEC Engineering (Medford).  Additional project credits for GreenWorks PC, where much of the early planning study and initial concept development was completed.

More OHSU Ecoroofs

by Jason King

As the OHSU CDRC project wraps up, a pair of other projects are currently underway, ready to start installation in a few weeks. These smaller roofs occupy the main building aggregation of the OHSU campus, including the Mark O. Hatfield Research Center and the C-Wing of main hospital building.  Both are  located on the fourth floor, separated by a 16 story tower and surrounding by taller building walls.  While not physically accessible except for maintenance, they are designed for low-maintenance and aesthetic views from surrounding structures.

The HRC is surrounded by larger buildings that wrap it on all sides, making it a challenge in developing a plant palette that will work in cool, damp, shady conditions.  The grid works off of the existing window pattern, creating a series of 8×8′ planted areas with maintenance walkways in between.  The area to the west is a staging area for an adjacent MRI – so needed to be kept open to allow for craning large magnets into place that are replaced every couple of years.  The ‘stream’ winding through the middle is a product of a natural existing drainage pattern of condensate from one of the upper roofs, breaking up the grid using  a combination of blue river rock and blue glass – making it a visible contrast to the vegetation when viewed from above.  Area will be planted with sedum cuttings and shade-tolerant perennials in different patches of texture, color, and flower.  The roof will have almost 1000 square feet of area when completed.

The C-Wing is more exposed to south facing sun, so includes a different mix of vegetation, as well as a slightly shallower depth of growing media due to structural capacity issues.  A lighter weight mix, at 2.5″ depth will keep saturated weights below 14 pounds per square foot to allow for maximum function with our allowable weight.  The bands work off existing windows to provide modulation to the thin expanse of rooftop, comprised of different mixes of sedum cuttings in three zones: 1) Green Cover; 2) Accent Bands, and 3) Color & Texture.  An access band continues from the “west roof”, allowing for maintenance and exiting from doors and roof hatch.  This roof will have over 1300 square feet of vegetated area, with a possible addition of 800 square feet to the south.

The proximity of these rooftops starts to develop a critical mass – along with a variety of other ecoroofs and terraces to greening the hill… and there are potentially more projects underway.  Check back for additional project updates on all of these projects.

BES Ecoroof Contract Supports Minority & Women-Owned Business

Contract gives Portland minority, women firms eco-roof work

From the DJC Oregon – Friday November 5, 2010 (by Nathalie Weinstein)

A quarter-million square feet of eco-roofs have been installed in Portland since the city’s Bureau of Environmental Services launched its Grey to Green initiative in 2008. But minority, women-owned and emerging small businesses say it’s still difficult for them to gain experience in what has become one of the city’s growing industries.

It’s not that these firms don’t have the technical know-how to perform eco-roof projects, said Dan Koffel, president of Snyder Roofing.  The problem lies, instead, with the fact that smaller minority- and women-owned businesses often can’t obtain bonding for eco-roof projects because they don’t have experience installing them.

The situation may change now that a $160,000 contract has been struck between the city and several companies, including Snyder Roofing, to get MWESB firms some experience in installing eco-roofs.

The city’s Grey to Green program is a five-year effort to install bio-swales, eco-roofs, street trees and other natural storm-water treatment systems around the city to prevent combined sewer overflows to the Willamette River. To construct an eco-roof, a waterproof membrane is placed on a conventional roof and covered with a growing medium that allows plants to grow. Eco-roofs significantly reduce storm-water runoff from building roofs, absorb carbon dioxide and insulate a building for better energy efficiency.

The city contracted with Snyder Roofing, landscape architecture firm TERRA.fluxus LLC, planting expert Teufel Landscape, Cascade Design Services and green workforce nonprofit Verde to identify and install up to 30,000 square feet of eco-roofs in Portland during the next two years. As part of the city’s efforts to get minorities and women involved in city contracts, 30 percent to 40 percent of all subcontracting dollars attached to the eco-roof effort will go to minority- and women- owned businesses, according to Alan Hipólito, executive director of Verde.

“Diversity in contracting is important anytime the government comes to the marketplace,” Hipólito said. “Sustainable development should be universally understood to mean economic, environmental and social equity. That triple bottom line is the idea behind the effort.”

The eco-roof contract also is expected to help identify prominent places within minority and low-income communities to install eco-roofs. With an eye toward encouraging building owners to install the systems, the BES offers an incentive of $5 per square foot of eco-roof. But the city says it has been tough to spread the news that the incentive exists.

“We advertise and send e-mails about it to Metro,” said Amy Chomowicz, eco-roof program administrator with the BES. “Then we wait for projects to come to us. But not everyone wants to listen to what the government has to say. With Snyder out there identifying projects for us, we can involve a broader sector of our community, as well as perform environmental projects outside of more affluent neighborhoods.”

No eco-roof sites have been nailed down yet, Hipólito said, but he would like to see an eco-roof go up at places such as the Baltazar Ortiz Center and the Native American Youth Family Center in Northeast Portland. He hopes the green roofs will encourage younger minorities to pursue careers in sustainable design.

“Developing eco-roofs at recognized institutions for communities of color presents an opportunity for people to learn what it is, why it’s there and who built it,” Hipólito said. “If they are in middle or high school, they can learn about opportunities for careers in construction and even to be the person who designs and engineers the eco-roof.”

Hipólito and Snyder Roofing this week met with members of the Metropolitan Contractor Improvement Partnership and the National Association of Minority Contractors Oregon chapter to develop a list of minority and women-owned firms to perform the painting, hauling and other contracts involved with an eco-roof installation. Soon, Snyder will begin meeting with these firms to talk about bid opportunities.

“With more projects like this, our children should be able to say to yours, ‘We had an opportunity to actively participate in environmental sustainability; I had an opportunity to build this,’ ” said Tony Jones, executive director of the Metropolitan Contractor Improvement Partnership.

Construction: OHSU CDRC Ecoroof

by Jason King

Some progress on the OHSU CDRC Ecoroof project, which is slowly coming together (and trying to hop-scotch around other building related construction).  In the past couple of weeks, the insulation, drain board, and irrigation has gone in for many of the areas.  The irrigation connected from ground level, brought up to the roof, then routed and cut into the insulation under the surface with stub-outs at valve boxes and other equipment.

The leak detection tape was installed at perimeters and around drains prior to installation of the additional layers.

Irrigation was installed at the third floor point-of-connection and routed up the side the building (no penetration of the building envelope was allowed).  These will be flashed with a metal cover to match the rest of the building flashing and protect the piping.

After a layer of filter fabric, the subsurface capillary irrigation is going in on Level three.  As pavers had yet to arrive, areas were marked out for layout, and irrigation was installed in planted areas.

The pavers started going in soon after – which are necessary for egress – and also form a small patio space on Level 3 for building users.

The Level three roof was finished off with edging & pavers.  There are some accessories like drain boxes and gravel edging material still has to go down, but it’s almost ready for some plants!

On Level 4, ecoroof components, irrigation, and growing media for the strip of ecoroof adjacent to the pathway and interior building hallway were starting to go in.

Also on Level 4, an additional evening crane lift staged more bags of growing media across the roof and media began to be spread.

Heading up on friday, where significant progress has been made on planting Level 3 and finalizing Level 4 – so more photos to follow.
