Taking Water Harvesting to High School 

When I got a call from Amy Bell, lead Landscape Architect at Groundwork Studio, about providing a high school with water harvesting activities, I couldn’t resist.  Look at that rooftop on the south side of the school building, draining onto an gravel-covered opportunity site!

A project-based curriculum for high schools, Water Harvesting on Site, is one of the results.  Initiated in early 2017 at at ACE Leadership High School in Albuquerque, we developed a set of activities that guide students through the main steps of designing with rainwater.  We also provided a conceptual landscape plan for part of the school campus that would sink stormwater into earthworks (basin, swale, berm) for landscaping plants and store it in a water catchment tank for a garden bed.

The preliminary curriculum is now offered to educators who are interested in integrating Earth Sciences, Mathematics and Design lessons on a school campus or other local site.  The focus is on the place where students go almost every day, where they can relate to stormwater as a resource for growing food gardens and healthy landscapes.

The curriculum is aimed at project-based programs where instructional support and materials can be provided.  The activities can be connected to STEM standards (Science, Technology, Engineering, Mathematics), plus Art!  In addition to project-based learning, this could work for an independent study program or even home schooling.

Considering the children and youth in this age of climate change, we need to generate on-the-ground experiences that connect rainwater, soil, and plants, leading to resilient landscapes.

Adaptive Actions with Tijeras Creek

When I first visited the Tijeras Creek Remediation Project two years ago, it was to explore large-scale earthworks: a system of basins, swales, berms and spillways.  I discovered that much more is occurring there.  The project returns natural processes to the upper creek’s floodplain and expands watershed awareness and resiliency know-how.

Before: Degraded Environment

Following the expansion of A. Montoya Elementary School, stormwater from the parking lot and rooftops flowed through culverts that dumped onto the stream bank.  But when it rains just two-tenths (.2) inch, over 300,000 gallons flows into the area.  The intensity of the water carved out gullies, carrying pollutants from the parking lots.  As water rushed through the gullies, it carried loads of soil into the creek.  Some people used the area as a dumping ground. Thus:

  • Water pollution
  • Groundwater depletion
  • Invasive plants
  • Loss of bio-diversity
  • Degraded public space.

Ongoing: Resiliency

The opportunity to develop solutions that mimic nature was something that Jim Brooks couldn’t resist.  Jim has offered volunteers a variety of skill-building activities using permaculture principles.  As Jim describes it, “We’re treating the water with respect when it falls into the site.” The teams practice a variety of adaptive actions, revealing soil as a living thing.  It’s a long-term process that includes new basin and spillway installations this year.  

Thus:

  • Water Harvesting with earthworks
  • Groundwater supports floodplain.
  • Clean stormwater enters creek.
  • Water is stored in living systems.
  • The plant /soil / food web expands.

The earthworks and soil techniques are applicable in many places where development and nature meet, and volunteers are inspired to practice them in their own places.

Work Parties Dig It

Querencia Green is coordinating work parties with volunteers for the spring and summer.  We’ll start on Sunday, March 20 with Albuquerque Involved volunteers and anyone who wants to participate (wear suitable work clothes).  Tools are provided but you can bring your own. The project site at 24 Public School Road is only eight miles from Albuquerque’s eastern boundary.

We’re also sponsoring field trips with high school classes to increase outdoor experiential learning! Teachers can contact Joanne via the Contact page.

More news about the spring events appear on Facebook Tijeras Creek Remediation Project.  

During 2015 and 2016, project support is provided by the PNM Foundation, and field trips with Highland High School are supported by Albuquerque Involved.  Thanks to all who are part of the resilient solutions!

Environmental Education in Place

Many school campuses have portable buildings, eroded soils, and bare landscape areas.  At the School on Wheels High School in the South Valley, our Places We Live team saw an opportunity for a small earthworks project.

During rainstorms, a downspout on a portable building flowed next to the building and the water collected and evaporated in a low area.  A bio-retention basin could protect the building, improve soil, increase infiltration and nurture new plants.

Terry Dunbar on site before installation

Joanne McEntire of Querencia Green joined Science Teacher Terry Dunbar at School on Wheels and the Environmental Education Association of New Mexico (EEANM) to install the water harvesting project during the workshop series Places We Live.

The series began with an educators’ workshop to provide the place-based environmental education curriculum from Project Learning Tree.  The South Valley MainStreet board chair, James Aranda, provided a cultural overview of the  neighborhood, which created a greater “sense of place” for the group. Barbara Garrity of EEANM and McEntire explored the Places We Live curriculum.

To focus on issues of water and the important values of trees, McEntire provided activity materials and reviewed key components of rainwater harvesting.  To prepare for the earthworks installation, she designed the basin and arranged for the needed installation materials, and a few science students put in some preliminary time on the site.

A multi-age crew of students from Jimmy Carter Middle School and School on Wheels, plus educators and crew chiefs, made the installation workshop an energetic success!  We built a ‘splash basin’ under the downspout, dug a larger, shallow basin for the runoff, lined the sides with rocks, made “sponges” in the bottom of the basin to catalyze microbial activity, and covered the bottom with woody mulch.

The crew planted a Desert Willow tree and Autumn Sage on the edges of the basin, which will expand the native plant diversity at the school.

Teacher Terry Dunbar enjoyed the following day with his participating students: “When our crew members came in this morning, they grabbed their friends and took them out to the site to show off their work.  They’re proud of what they accomplished.”

Future possibilities for students in the expanded outdoor learning environment include observing microbes in the soil sponges, comparing it to the native soil, supplementary watering in the first dry season, and adaptive actions that repair or improve the site.  The other educators who joined the team hope to create water harvesting projects at their schools or homes.

This team project was made possible by the Albuquerque Community Foundation.  Crew

Trees, Hot Cities and Water

Re-thinking trees and rainwater

The connections between trees, stormwater, and the soil / water web are not always obvious in our cities and towns.  With the approach of El Nino, it will help to maintain a broad view of climate change and long-term drought, and to keep in mind the human inclination toward the hydro-illogical cycle!

Hot cities

The urban forest in the mid Rio Grande region has been in trouble for a while.  The drought and invasive insects have stressed older trees and caused many to die.  Impervious pavement increases with urbanization, which can increase the heat island effect.  The graphic report at Climate Central reveals that Albuquerque ranks second in the US with the biggest difference between urban and rural temperatures.

The researchers looked at summer urban heat islands (average daily urban-rural temperature differences) over the past 10 years.  Albuquerque’s urban area has soared 22 percent higher (in the cities) than in surrounding areas (with less impervious area) on some summer days. Hotter temperatures mean more ozone, a dangerous air pollutant.

More trees and parks, white roofs, and alternative materials for urban infrastructure can help reduce the effects of urban heat islands.  Climate Central

The Arbor Day Foundation provides a visually complex infographic showing the differences between an urban water system with a few trees compared to a thriving urban forest.  Look at the changes that occur on parking lots.

Treeless Parking Lots are unsightly, add to stormwater runoff and are a source of heat that is not only uncomfortable but increases air pollution.  Arbor Day Foundation

Earthworks, trees and water go together!

It’s encouraging to see results of a study Doubly Green Trees from the American Society of Agronomy: earthworks (bio-retention basins and swales) and trees function very well together.  Santa Fe based designer Aaron Kauffman reports that the water content in basins and swales is greater than in areas without earthworks.  In New Mexico, more water retention = healthier soil and plants.  No big surprises there, but more hands-on implementation within our communities is necessary.

Water infrastructure plus

With the global water crisis growing and the reality of climate change and financial impacts upon us, The Economist has joined the conversation.  “Working with the Flow” includes the infographic shown below.  Natural with engineered water infrastructure integrates more aspects of the natural ecosystem and produces more benefits, but financing systems need to go through a major paradigm shift.

Natural infrastructure provides services that underpin the way we manage our river basins and therefore the way we grow food, generate electricity, and supply water to cities.  At the same time, it maintains important biophysical processes, and endows our environment with species and habitats.  Critically, water drives our climate, and therefore climate change affects the hydrology we so heavily rely upon.  The majority of finance directed towards adaptation to climate change is used to solve water management challenges on the ground, and yet water is poorly integrated into climate change policy discussions and funding proposals.    Mark Smith, The Economist

As our older trees die off, we can adapt and create more resilient urban and rural landscapes.  Whether you live in a dense central area with numerous workplaces and homes, a neighborhood with single homes, or dwell beyond the fringes of the city, re-think trees, water, and soil.  Advocate for more classes and workshops, water harvesting and tree incentives, and skill-building programs to generate land and water resilience.

Planting the Water for Green Learning Spaces

Do you have a favorite school, one that you attended, or where your children learn?  Do the outdoor areas provide a natural experience?  It seems that many school campuses around Albuquerque have unused spaces that could offer students outdoor opportunities. Other schools feature water-friendly green infrastructure with new facilities that are designed by professionals.

The swale near the Highland High Science Building in fall season

A few years ago, the Science teachers at Highland High School were happy to move into a new Science building, but there was no landscaping near the main entrance.  Gale Borkenhagen teaches the Advanced Environmental Science class, and she connected with other teachers who realized that the barren space was not going to pass.

Stormwater from the rooftop flows onto the site through two downspouts.  A retired teacher, Maura Montoya, dug a swale to slow and convey the water.  Overflow water was then conveyed into a nearby bare space through a pipe under a sidewalk.  Gale generated small grants from local funders, and bought a number of diverse trees.  Students have helped maintain the grove, with custodians adding water as needed.

Gale Borkenhagen visits the grove in winter.

The grove now becomes a mini-oasis in monsoon season, and it’s a textured, colorful space year-round.  Many of the trees provide shade on the building (saving energy) and an “encounter with nature” that people need for mental health and functioning.

Creative teachers nurture the love of nature throughout the public and charter school systems.  Teachers and students are building and growing edible gardens, and rain barrels or tanks can store rooftop rainwater for use in the dry months of the growing season.  There’s a lot of rooftops on school sites in New Mexico’s cities and towns .

Exploring an unused space at Valle Vista School

Observing the low and high, pervious and impervious areas.

Recently, two visitors explored a barren space with teacher Mike Goss at Valle Vista Elementary School.  Here is an opportunity site for a small grove that students can plant and love.

Currently, the water that flows off the nearby rooftop collects in the space with very compacted dirt, and slowly evaporates.  Instead, it could infiltrate into broken, loosened up, amended soil within earthworks (basins and swales), allowing new plant roots to uptake the water.

 Old and New Drainage Infrastructure

Highland High – drainage area at downspout on old building

Like many old school campuses, Highland High has a number of degraded outdoor spaces and stormwater problems near old buildings.

Look for new buildings that are built by the Albuquerque Public Schools; they may feature green infrastructure that was included in the design and budget for the building’s construction.

The newest building on the Highland High campus features connected basins on two sides of the building, with trees and bunch grasses planted near each basin (below).

Inspiration on PBS KNME in January 2015

Water Blues Logo

New Mexico’s PBS station KNME will broadcast the documentary film WATER BLUES GREEN SOLUTIONS in January 2015.  The film presents US cities that are using stormwater to generate resilient landscapes in public parks, school yards and along streets.  Local Green Infrastructure supporters and designers made a request with Querencia Green to KNME to air the program – and KNME scheduled it on two stations.

  • Mon. Jan. 12          10:00 pm        KNME 5.1
  • Wed. Jan. 14           5:00 am         KNME 5.1
  • Sun. Jan. 25            9:00 pm         KNMD 9.1

The stories about urban water are from Philadelphia PA, Portland OR, The Bronx of  NYC and San Antonio TX (with its thorough water conservation and re-use strategy).  Neighbors and youth are involved in some of the featured projects, generating ecological know-how and job skills.

In addition to the video, WATER BLUES GREEN SOLUTIONS offers a website with tools for activating green solutions for flooding, pollution, and scarcity. It includes K-12 and higher education learning modules that could be adapted for arid places.  The video can be purchased on DVD.

“This initiative is designed to promote public education and awareness of “green infrastructure” and how natural processes can interface with and complement existing gray or manmade infrastructure. The ultimate project goal is an informed citizenry that is empowered to participate in the development of place specific strategies for addressing water issues.”   Penn State Media

Community work

Many  green infrastructure techniques that work in wet climates have been adapted to suit the Southwest’s arid places; numerous New Mexicans are testing and implementing them.  A few of our community places highlight water harvesting, soil building strategies and native plants that support pollinators and other wildlife.  Expertise is growing as open courses for practitioners are offered.

Local government agencies have started to change the rules about stormwater to encourage rainwater harvesting with beneficial uses.  There are several wonderful environmental education programs that guide young people to care for the Rio Grande watershed.

More inspiration is advisable.  Watch WATER BLUES GREEN SOLUTIONS.
