BES Calendar features two projects from TERRA.fluxus

by Jason King

Just in time for 2012, the new calendars are available from the City of Portland, Bureau of Environmental Services and their Sustainable Stormwater Management program.  This annual publication shows off some of the interesting new projects built around Portland, and it was a nice surprise to see two months that included some of the recent work of TERRA.fluxus.  April features a couple of recent works – in particular the Vertical Wetland project completed at Move the House, project for Urban Development Partners, with art feature by Ivan McLean and funded by Metro, that funnels roof water through Corten sculpture visible from SE Division Street.

As mentioned in the calendar:

“Disconnecting a downspout is a simple way to remove roof runoff from the combined sewer system and protect water quality, and it offers opportunities for creative ways to disconnect.”

Also in June, a nice shot of the newly planted living wall at the same project, Move the House- showcasing the idea of vegetated walls, which contribute to sustainable site design – in this case screening the very prominent trash enclosure in the center of the outdoor plaza area – adding a burst of greenery to an item that is often considered an eyesore.   As mentioned in the calendar:

“Green Walls use vertical surfaces to green and beautify our cities.  Green walls can help reduce a building’s energy use and outdoor air temperatures, capture stormwater, or be used for urban agriculture “

Green Roofs featured on Design*Sponge

by Jason King

Surfing the web lately, I stumbled on a post from popular blog Design*Sponge offered some interesting images of a familiar green roof or two.   Some of the work I collaborated on with the non-profit iteration of Ecoroofs Everywhere between 2002-2005.  Another, seen below, is the Elgert/Sweeney Residence from 2008, the green roof designed by Jason King and installed by E2 in their new incarnation as a for-profit installation firm.  The project was designed by Brian Sweeney (BPS Architecture) and the green roof was used to fulfill Portland stormwater management manual guidelines.

Elgert/Sweeney Residence Green Roof

As Design*Sponge founder and columnist Grace Bonney reflected on a trip to Portland:

“One of ideas I wish Brooklyn would adopt is Portland’s love of living and edible roof gardens.  I’ve seen roof gardens in New York before, but I’ve never seen them used so frequently as I have here in Oregon. They’re on residential homes, commercial buildings and growing naturally on park buildings around town.”

The post included a number of other projects from Portland, and a few that I worked on with Ecoroofs Everywhere as a non-profit, including the Hawthorne Condominiums and the Orpinela Guesthouse, photos of which are found below.

Thanks to Ecoroofs Everywhere for the collaborations over the years as a non- and for-profit company, and for Design*Sponge for the info for reminder and coverage of these great projects.

A Trio of Noted Projects

by Jason King

Sifting around the wonder that is the internet, it is always a surprise to see something that references a project you’ve been involved in.  I managed the trifecta with references of recent project work in media and as part of educational materials.  Enjoy these little snapshots of projects.

HEALING ROOFTOPS

First, my friend and colleague Elizabeth Hart, who is a Sustainable Technologies Specialist at Tremco Roofing penned an article in Healthcare Development Magazine on ‘Green Roofs on Health Care Facilities‘, mentioning projects at Portland’s OHSU Hospital, as well as the Van Ness Medical Office Building in San Francisco, all projects designed by TERRA.fluxus.   The benefits of green roofs in hospitals is hard to quantify, but there are signs that this particular building type may be well-suited for multiple reasons for vegetated roofs.  As Hart mentions in her article:

“While the benefits can be attractive, a major setback for the green roof industry is that there is really no way to create a broadly applicable baseline for the benefits of adding a green roof.  Energy savings in the building, the capacity for storm water control, the exact number of years you can extend the life of the roof membrane – these factors shift with each unique building situation and green roof system.  They are living organisms and their functions vary widely with each microclimate, building type and method of install.  The lack of an easily quantifiable return on the investment can prove challenging in the early planning stages.  Despite this, green roofs seem to speak for themselves by how widely they have been adopted, and how rapidly they are changing the “nature” of hospital rooftops.”

 

INNOVATIVE IRRIGATION

Second, the 2011 Brochure for KISSS America – supplier of subsurface capillary irrigation, which TERRA.fluxus used on the OHSU CDRC Green Roof project, the first use on a green roof in the Portland area.  The beauty of sub-surface capillary irrigation is that it eliminates the issues with regular drip in porous, lightweight rooftop soils.   Click here for a link to the full PDF, showcasing some other great projects using this innovative technology.  A snapshot of the brochure showing the installation photos:

BROWNFIELD SUCCESS

Finally, a fact sheet published by the Environmental Protection Agency as part of their Brownfield program includes a ‘success story’ on the Emerson Street Garden, as formerly polluted site that was transformed by the community into a model for transforming underused properties into community assets.  TERRA.fluxus was involved in preliminary site planning for the garden, translating workshop comments and feedback into a roadmap for the site to follow as it took shape.  The site has evolved rapidly since these photos from last year, so will post more soon.  The fact sheet offers lots of background on the garden evolution, as well as resources related to brownfield redevelopment.

Got Urbanism?

by Jason King

In the upcoming April issue of Planning, the magazine of the American Planning Association, there is an interesting article by Jonathan Barnett, exploring the predominance of the use of the word ‘urbanism’ to describe the phenomena of the contemporary city.  Derived from a post on Landscape+Urbanism, – along with expanded conversations with PSU Professor Ethan Seltzer, fellow PSU Urban Studies student Allison Duncan, and landscape architecture colleague Brett Milligan -  Barnett takes this and gives shape to the range of terms, expanding and defining the range that exist – and hinting that even these 60 may just scratch the surface in common usage.

Pearl District Ecoroof Tour

by Jason King

Our second tour for Ecoroof Month (a partnership between Green Above Ground and Bureau of Environmental Services)  focused happened on some projects in Portland’s Pearl District, and a group of 25 people braved chilly temperatures to see a range of interesting projects.   Like the last tour, we chose accessible projects that our team worked on in some capacity to outline a range of different applications.   The tour started at the Asa Flats + Lofts, which offers a range of  intensive and extensive ecoroof, as well as a wide array of adjacent projects.

The final stop was closer to the Willamette River, viewing down from the Encore Condominiums – which features a 1500 s.f. vegetated roof featuring a lightweight system with pre-grown vegetated mats.  The goal of this project was to provide stormwater management, as well as to provide views from upper units to the smaller live-work structure below.

Quotable: The Green Roof Manual

by Jason King

A trip to Powell’s yesterday yielded a number of fine resources for the ever-expanding library.  One of note is the long-awaited publication by Ed Snodgrass and Linda McIntyre of a new resource, ‘The Green Roof Manual: A Professional Guide to Design, Installation, and Maintenance’ (Timber Press, 2010).

I spoke with Ms. McIntyre last year at length while they were in the midst of writing, and was happy to see both a reference to my Landscape Architecture editorial, as well as a nice quotation amidst the pages of the book (pages 164-165).  The focus of the discussion was based on the role of design not just for aesthetics, but as part of an integrated process to generate cost effective solutions to make projects a reality:

“Landscape Architect Jason King was able to safely eliminate most of the metal edging on a project and save about $2.50 per square foot.  He also tries hard to find appropriate local materials to save on transport costs, as well as for the ecological benefits.  No single tweak will necessarily save a lot of money, King says, but factoring costs into decision-making throughout the process can cut the price per square foot almost in half on some project. “That can make the difference between a green roof being built or having it value engineered out of the project.”

Hidden Hydrology Origins 3: Disappeared Streams Map

by Jason King

Over the next week, I have been outlining some of the inspirations and precedents related to the idea of Hidden Hydrology of Portland, as this project has been shaped and has evolves across many years to it’s present incarnation.  As I mentioned in the preliminary overview, one of the main inspirations was the map of ‘Disappeared Streams’ that was produced by Metro.  My first encounter with this map was during a presentation at DaVinci Arts middle school, as part of the preliminary planning for what would become their beautiful water garden.  At the time I was working with local non-profit Urban Water Works – and the students were showing off many of their water-related side projects, including hand-made flowforms, studies of water movement, and mapping.   One student had a GIS application that was showing the disappeared streams – which has stuck in my brain every since.  Metro now publishes it in map form – available at the Data Resource Center – along with many other great maps.

As I mentioned there are a few methodological caveats to this map – as it is not a historical representation of actual streams, but looking more specifically at locations of potential water routes.  From the map, some of this language:

Development patterns in the Metro region have historically resulted in piping, culverting, or filling of streams and stream beds.  A computer mapping program was used to evaluate the terrain in the region, and to generate areas where major streams (those draining 50+ acres of land) may once have existed.  While this does not represent an authoritative analysis, it does visually describe the effects of urbanization on the regions natural systems.  This exercise indicates that an estimated 388 miles of previously existing streams are now underground.”

The coding of the map is pretty striking (the choice of ‘blood’ red I think fitting) when viewed as a whole (above) particularly noting the core area of Portland that has been denuded of streams over the course of 150 years (below, closeup of City of Portland), where flatter areas were developed for Eastside residential, and margins on the Willamette filled in for industrial development.

You can also get a close-up view,including the central business district – seen in closeup below.  Notice the existing pattern, where streams are kept somewhat intact in the west hillsides (topography being somewhat of an antidote to piping), then quickly buried when they reach the urbanized area.  Tanner Creek, one of the hidden streams we will be studying closer, is captured as it originates from the Oregon Zoo and cuts through the northwest corner of downtown.

A relatively simple map that is more evocative than accurate, but does much to reinforce the ideology of what is hidden beneath our developed urban areas.  As I mentioned, it has stuck with me (and I’m glad Metro still has these available).  One of the stronger and original inspirations for the project, it continues to entertain and inspire investigation into our hidden hydrology.

REWIND: 2010, A Year in Review

by Jason King

What a great year.  Ok, while not a complete year (the firm began operations in mid-February), 2010 was a great start to TERRA.fluxus, with a number of highlights, projects, research, and exploration worthy of a recap.  Rather than a chronological walk through the year, there are a number of themes to be captured within the projects and activities of the firm, which ranged through the west from Washington & Oregon to California, and included a wide variety of explorations of planning, design, and urbanism.  Starting in the home office, I first moved to a shared space with Design Department, then finally to the current location at Tenpod, another  shared office space inside the Rocket Building on East Burnside, centrally located and packed with a range of creative folks.  The changes of scenery have been great, and the people I’ve met, make me feel fortunate to live and practice in Portland.

Starting a business is hard. This fact is not made easier by a tepid economic climate, but I felt I had the opportunity to grow and expand the nature of my experience and the potential for landscape architecture.  So I did so , because I thought I had something to offer clients and the community.  My business model is simple – do innovative client-based work in a range of areas, balanced with equal time for research and speculation of new ideas.  The ability to take on work that is meaningful, challenging, and vital is rare.  The opportunity to do it for a living is a gift.  So, in year number one, I must give thanks to my clients and collaborators, both old and new, who trusted me with their projects, ideas, sites, budgets, and visions.  I wholeheartedly appreciate it, and hope to continue to provide services in the upcoming year.

Green Above Ground

The work in the realm of Veg.itecture was front and center for TERRA.fluxus in 2010, including over 40,000 s.f. of projects designed and/or installed in 2010, augmenting the total ecoroof square footage i’ve worked on over the years to well over three acres.  Always trying to push the envelope for understanding vegetated roofing, I also compiled some new research related to the specific requirements of ecoroof irrigation in the Portland region in a presentation for an on-going group that I helped to co-found, the Green Roof info Think-tank, or GRiT, for short.  In addition, I published a DIY Guide to small scale ecoroofs, and also helped lead the Ecoroofs 2010 Tour as part of the annual ecoroof Vendor showcase that highlights the great companies in the industry throughout the region.

Built work included a number of great OHSU Projects including the Child Development Research Center (CDRC) which was constructed this year, and the Hatfield Research Center (HRC) and the main Hospital C-Wing projects that will be installed in early 2011.  Other projects include the ongoing development BPA 905 Building project, working with the GSA to provide stimulus-funded improvements to multiple roofs on this headquarters building in the Lloyd District.  This project will also happen in 2011.

A major highlight was winning the RFP and the award of the contract from Bureau of Environmental Services for the Ecoroof Design-Build Contract for the Green Above Ground Collaborative, along with wonderful partners Snyder Roofing, Teufel Landscape, Verde, and Cascade Design Professionals.  Our goal of 30,000 square feet of green roof, along with tours, education, a proposed video and mobilization of emerging, women, and minority-owned businesses will provide a ton of excitement through the next two years, expanding on our collective experience in the industry.   This award was also mentioned in local media publications such as the AGC Oregon newsletter and the DJC Oregon.

Media coverage was also thick for the arrival of Ty Pennington and the crew from Extreme Makeover: Home Edition, where the Green Above Ground crew participated in the fast-paced design of the vegetated roof for the Oregon Center for the Deaf in Salem.  It was wonderful to be involved in this great project that benefited so many, while giving green roofs some visible media coverage on a national forum.  A different small scale roof terrace for the Reliable Apartments went as well.  Outside of the region, I finished up Van Ness MOB (my first project in San Francisco) which will be built in 2011, and locally, got to see the completion of a few older projects done prior to starting TERRA.fluxus, such as the First+Main Building in downtown.

Visualizing Vegitecture

An adjunct to the built work around Green Above Ground, there are visuals to sell future projects.  Many of these were done, working with Tremco, for projects in California,  including the Wilshire-Rodeo roof terrace in Los Angeles, which re-envisioned a drab commercial rooftop into a lively outdoor meeting space.  Another LA project was for Cedars-Sinai Medical Center where views from patient rooms overlooked a gray gravel roof, which also led to significant heat gain in the building.  Moving to Oakland, there was also the Washington Medical Center which combined green walls and roofs to provide aesthetically-pleasing (and sustainable) views from patient roofs instead of drab rooftops and mechanical equipment.

This concept expanded on an idea I believed strongly in, that of biophilic design, which engages our connection to nature and natural materials and processes in the creation of healthy and restorative spaces.   While green roofs are great for a number of reasons, the connection to building occupants through visible engagement with nature is one with a special power in hospital settings, where these can aid in many health outcomes.  These visuals aid in convincing decision-makers of the beauty and utility of these concepts.

Urban Agriculture & Food

Continuing the theme of rooftops, this time mixed with food, I had the opportunity to again be involved in the planning, design, and installation of the Multnomah County Hope Garden, a rooftop urban agricultural showcase that provides food for local hunger-relief agencies.  This project, in its second year, donates over 500 pounds of locally-grown produce, cared for by the County’s Green Team, in just a small  200 s.f. area on their rooftop.   The work in urban agriculture led to some great networking, capture here in a great blurb on the ASLA Sustainable Sites PPN blog, which discussed my presentation up at University of Washington on urban agriculture ‘Designing for Urban Food‘ – where I shared the stage with great minds like Deb Guenther from Mithun, Keith McPeters’ from GGN, and Jeffrey Hou from UW.

I also meet some great folks teaching at UW, like Brandon Born and Thaisa Way whom have offered additional opportunities for learning and interaction.  While my time on the Food Policy Council came and went, there were some other exciting projects like the community based remediation of the Emerson Street Garden – a brownfield site turned community gardening, and the site planning for the WVMC Hospital Garden in McMinnville, planned to help feed patients fresh produce at the hospital.

Another highlight was the opportunity to show off the Chicken Cube, our ecoroof topped coop design-build project on this years Tour de Coops, an annual tour of innovative chicken homes put on by local non-profit group Growing Gardens.  The tour had over 300 people, and the coop even garnered some TV time with a short spot on the local show Garden Time – which was a blast – a good use of my fifteen minutes of fame.  On the subject of coops, I also had a great opportunity to be guest juror for an internal coop-design competition sponsored by SERA Architects, as part of a fundraiser for local arts group PICA.

In addition to chickens, the food cart phenomenon was in full gear, and one of my first commisions came working on design for a food cart pod on a derelict brownfield site in Southeast Portland for one of my favorite clients, Urban Development Partners.  This forward thinking developer took a vacant parcel which will eventually be built-out, and constructed this pop-up site, opening in July with a few pioneers.  The site has quickly filled up with over 15 carts, expanding to include covered areas and heaters for all-weather dining.  This planning and design experience also included a quote in the recently released book Cartopia, authored by friends and colleagues Kelley Roy and Kelly Rodgers, which is literally flying off the shelves since it’s October debut.

Ecology & Site Remediation

An ongoing project is the Bradford Street Property where I am conducting multi-year evaluation of remediation plantings done on this waterfront site along the Willamette River in North Portland.  There is also a remediation component for the Emerson Street Garden and 2011 offers opportunities for more specific technical aspects of phytoremediation as this aspect of the lead-contaminated site begins in earnest.  Another ecologically notable project that has also continued is the work around the wetland area for the Asante Court Park in Medford, Oregon.  This multi-phase project, working with uber client Asante Health System, began with wetland mitigation plantings, this year followed with the installation of the new park area plantings to provide more sustainable design than lawn and non-native plantings.  New phases include continue this theme with additional common area plantings and the addition of the stormwater outfall garden, which are in final design and approval process, to be installed in Spring of 2011.

great article showed up in Multi-Family News focused on sustainable landscaping, where I was able to drop some ideas on ecoroofs, efficient irrigation, appropriate plant selection, and ecological stormwater design.  These principles were also embedded in our proposal for the Min Zidell Garden at the National College of Natural Medicine, which unfortunately we did not get – but the experience working with the team and the great folks at NCNM was truly wonderful, and I’m sure the results will be fantastic.   Another small project includes LEED evaluation for Creekside Clinic in Medford, (operated by Asante).

This site-scale work continued with development of native plantings and LEED evaluation for the Reliable Apartments in Southeast Portland, and will continue into 2011 with some Metro-funded sustainable site improvements to the Move-the-House Apartments on 38th and Division.  The proposed work, in addition to flow-through planters and permeable pavement, will include a vertical wetland sculpture, habitat nodes throughout the site, a vertical green wall, and canopy ecoroofs.

The Urban Laboratory

The beginnings of the year continued the on-going activities related to the Oregon Solutions process for Community Gardening, along with the seminar class at University of Oregon investigating the ‘Urban Edge‘ of Portland.  Both of these projects were specifically representative of using the Portland region as a working laboratory for study.  In that vein, the work on Landscape+Urbanism also continued, with more focus on local issues and ideas as I study my home place in new and exciting ways.  The writing led to a great connection and interview with colleague Christian Barnhard for his great new podcast series LANDCAST.

Work also continues on the PDX Greenmap, to provide a resource for locating information on a range of sustainable resource throughout the Portland metro region.  Also, the next iteration of the urban laboratory to continue into the next year will be recently unveiled Hidden Hydrology Project – which will provide a more robust information gathering, analysis, mapping, and exploration of a range of topics concerning urbanism, water, and the definition of our place.

Community Building

Per my business model, I’ve had the opportunity to work on a number of community-based activities and projects around the region.  There are educational items like the  tour of sustainable sites in downtown for the World Affairs Council of Oregon as well as more expansive tours and workshops such as the great  Oregon Sustainability Experience that brings folks from out of town to learn from Portland about sustainability and urban agriculture.  I was also honored to be a juror for the BEST awards, which awards local businesses pushing the boundaries of sustainability.  Pro-bono work included the design for the Extreme Makeover Ecoroof, the Hope Garden Rooftop Agriculture, and the Willamette Valley Medical Center garden project.

Other projects include the afforementioned Emerson Street Garden included a series of workshops and alternatives that were developed over six months, culminating in the final design concept and groundbreaking in mid-summer.   My involvement in the garden sprang from the connections made during the Oregon Solutions Gardening project – which included representatives from the amazing Groundwork Portland – who have plans for many brownfileld sites throughout Portland.  A community-oriented proposal for the Seattle-based ideas competition Holding Patterns garnered an honorable mention from the judges as well, liking our take on the Urban Voids Matrix, a notion of ‘A Modular Approach to Building the Sustainable City’ that looks at the three typologies of the site, hole, and frame within a matrix of food, community, ecology, and materials.  This award-winning project offers potential for vacant properties not just in Seattle, but also in Portland, which will be explored further in the next year.

Check out the specific links for more information and references for this projects.

I, for one, can’t wait for 2011… it’s gonna be another great year.

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.

BES Ecoroof Contract Supports Minority & Women-Owned Business

by Jason King

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.
