Advocacy & Sustainability Corner

WHAT’S IN THE WORKS AND ON THE HORIZON

The California Chapter’s Advocacy & Sustainability (A/S) Task Force was formed in January of this year. We considered what advocacy and sustainability means to us as members and a professional organization. We also considered what is it that we advocate for because “advocacy” can mean different things from one person to the next. As APLD California members, we advocate for:

  • Our rights as professionals to practice our craft.

  • Legislation that supports our profession and our commitment to the environment.

  • Our clients to enjoy healthy and beautiful living spaces designed by creative and qualified professionals.

  • Biological diversity, conservation, protection, and regeneration at all levels.

  • Cultural, social, and racial diversity, equity, inclusion (DEI), and equality.

We kicked off the with a brainstorming/information gathering session in which a graphic recorder created an illustration on the spot of our discussion. Here is a snippet of that illustration. To view the entire illustration and to learn more about this type of communication tool published in the May issue of Design Online, click here.

Based on the top priorities that were identified for us to engage in at this time, we formed these committees: Website, Legislation, Firescape Education, and Healthy Pots, Healthy Planet Committees. Here are reports from the committees about what’s in the works now.

by Marcia Scott, Vice-President, Sacramento District, Member of the Website Committee

Website:
Our A/S Task Force started as an exciting exercise in herding cats: We generated a lot of ideas (we’re designers after all) but needed organization to implement them. We also wanted to be able to share those ideas with all our California members. The obvious choice was to use our existing APLD California Chapter website. We have SO many ideas that we quickly noticed the existing A/S website page would not accommodate them – hence a tiny Website Committee was formed. We have lofty visions… 

We’re rebuilding the A/S page with the heading of Advocacy as the main page. Subheadings that align with what we advocate for, as described above, will be:

LEGISLATION — EDUCATION — ENVIRONMENT — DIVERSITY, EQUITY, AND INCLUSION (DEI) — OUTREACH

Our Website Committee’s goal is to have a working version for you to use before the end of this year. We sincerely hope our website becomes a regular landing place and valuable resource for our members.

by Sophia Cunningham, Chair, Bay Area District’s Diversity, Equity, and Inclusion Committee

Diversity, Equity, and Inclusion:
The Bay Area District of APLD CA formed its Diversity, Equity, and Inclusion (DEI) Committee in July 2020, following the social justice uprisings around the country. As we reflected on this watershed moment, it became overwhelmingly clear to us that we cannot effectively advocate for a sustainable future without including social justice in that advocacy. 

Our goal is for the APLD to reflect more truly the world around us: a multicultural world rich with diverse identities and experiences. We will provide APLD members with educational resources and practical tools to deepen their understanding of equity and justice issues within our profession, enabling members to incorporate DEI work into their own practices. 

The committee is looking forward to award-winning landscape designer and horticulturist, Wambui Ippolito, lecturing on historical and present-day immigrant influences in American landscapes, on July 7th at 3 p.m. Register here.

 

by Jodie Cook, Member of the FireScaping Committee

Firescape Education
Increasing fire danger throughout the state has made it more urgent that California’s design professionals receive comprehensive, standardized training in FireScaping the residential landscape. To fulfill this need, the A/S Task Force has convened a FireScaping Committee charged with researching and developing a science-based curriculum to make designing at-risk home landscapes both fire resistant and biodiverse. 

“Ecologically rich” and “fire-resistant” are not mutually exclusive terms.  While the task force is now in its early stages, our goal is to produce a program that design professionals, armed with vetted information, can use to create landscapes that protect homes while enhancing the wonderful biodiversity of our unique state.

 

by Karen Hunt and Lori Cox, Co-chairs of the Healthy Pots, Healthy Planet Committee

Healthy Pots, Healthy Planet:
In the midst of the Pandemic, the APLD Sustainability Committee launched the first phase of its "Healthy Pots, Healthy Planet" Initiative in March. The endgame is a major reach for us: the goal is to make a tangible difference in the reduction of plant pots made from virgin plastic and to yield more pots that are plantable. We will know we have made that difference when all of us in the Green Industry (in particular landscape designers, architects, contractors, and gardeners) can ask for and receive more sustainable pots that meet our performance expectations, and that those pots are readily available, affordable, and the norm. 

This is a major undertaking for APLD, but one that we think we can accomplish. We also know that we are playing "the long game," as they say.  Its success will hinge on many, many challenging activities that will take all of our Chapter’s members to help with, starting with expanding the sign-ups to the coalition and eventually including forming partnerships with dozens and dozens of companies, organizations, associations, and key governmental departments across the United States. Please begin learning about APLD's most ambitious program to date by clicking here.

by Francesca Corra, APLD, CA Chapter Past President, Member Legislation Committee

Legislation:
The Legislation Committee of the Task Force has been tracking about a dozen bills as they go through the California State legislative process this year. The process has been pretty interesting as we are guided by EEC (Environmental & Energy Consulting), so we are not just floundering on our own, trying to figure out what’s what. As a committee, we started out with a list of keywords to narrow the field and then picked the bills that were of the most interest to us. The bills we chose are mostly dealing with environmental issues. EEC sends us periodic updates, in the form of a matrix, so we can see the progress of the bills as they pass through different houses and committees. We have the option to lend our support to these bills if we so desire. The goals of this exercise are to become more familiar with our legislative process, foster alliances, and to create visibility of APLD as a leader in promoting environmental issues. Always, we are on the lookout for any bills that might affect our right to practice…eyes open and ears to the ground!

 
 

“Years ago, I wondered why I’d want to pay to be an APLD member. What did APLD have to offer me? Aside from the camaraderie (which, actually, is a big deal), and the idea-sharing (another big deal), for me the PRIMARY reason for becoming a member was retaining a landscape designer’s Right to Practice. 

I already was paying for a business license, paying my taxes to the state, and even buying business insurance. I’m thinking: I’m running a legitimate business, right? And my clients want my services. And I’m pretty well educated at what I do. So, how would I feel if the state dropped in to tell me I could no longer make money from providing services that I see are needed and wanted?

The Legislative Committee is coming up with ways to keep our identity – our Right to Practice.”

Marcia Jimenez Scott, Vice-President Sacramento District, Legislation Committee

 
by Deborah Robertson-Christman of the Legislation Committee

by Deborah Robertson-Christman of the Legislation Committee

Here’s an example analysis of a bill that’s being tracked: The wheels of government turn ever so slowly towards making change for the better. The environmental justice planning requirements bill SB 499 is amending a section of the government code to put more teeth into enforcing land uses that do not impact the health of disadvantaged communities and do not degrade the local area…water, air, soil. A hearing was scheduled for April 8 and was cancelled by the author Senator Connie Levya.

On the MWELO front, the Department of Water Resources (DWR) has reconvened the Landscape Stakeholders Advisory Group (LSAG). The Governor's Water Resilience Portfolio (WRP) identified simplifying MWELO as a priority task. AB 2515 gives DWR direction to update MWELO in synch with CA Building Standards (CALGreen). To that end, LSAG members are asked to think about how DWR would simplify MWELO, without weakening the standards, to make it more effective. If you’d like to join the LSAG contact Julie Saare-Edmonds at Landscape@water.ca.gov.

Designer Tools & Tips

 

WORKING WITH GRADES IN LANDSCAPE DESIGN

by Chris Grampp, Landscape Architect (#2499, California) Landscape Architecture Program Director, Merritt College Oakland, CA

by Chris Grampp, Landscape Architect (#2499, California)
Landscape Architecture Program Director, Merritt College
Oakland, CA

My teacher, employer, and mentor Edward Janelli used to say trees and grades were the two most important parts of a designed landscape. I agree with Edward. In their most primary state landscapes have two shapes: vertical and horizontal. Trees represent the vertical realm, and among the numerous things they do for a design, they establish spatial definition. The ground represents the horizontal realm, and is basically the floor upon which everything in a design comes to rest. Once trees and grades come into harmony with one another, a substantial part of a design is accomplished.   

Edward also used to say that the best grading design is the one that you’re not even aware of. What I took him to mean was that good grading design was so integrated with all the other parts of a project, that it didn’t stand out as an entity in and of itself. 

In this light, here are some ways that I’ve approached grading, and some suggestions for how you might also do so:

• when you start a project, get as much information about the lay of the land as you can. Ideally you’ll want to shoot elevations with a zip level, or have someone do it for you, and create a contour map. Without this information it’s going to be very difficult to assess drainage, estimate cut and fill quantities, calculate wall heights and stair layouts, and much more. 

• always pay attention to how water moves, and grade according. Water movement can make or break a design, and points to the need for a contour map or at least key spot elevations to determine high and low points. You can predict water movement pretty well with a contour map: just draw arrows perpendicular to the lines all over the map; where the arrows point is where the water wants to go. 

• color your topo map according to steepness of slope. A colored may will allow you to assess site potential quickly. Here how I do it (see accompanying diagram above):

Green: flat or nearly so (1-5%; conducive to gatherings, work areas)
Yellow: gentle (5-15%; a few stairs, walls probably not necessary)
Orange: moderate (15-33%; stairs, low-medium walls, rising installation costs)
Red: steep (33%+; high walls, erosion, high installation costs)
Blue: depression (rain garden, pond, wind shelter)

 
 

PROBLEM SOLVING IN THE LANDSCAPE — HILLSIDES DESIGN

From Uncomfortable Hillsides to a Meaningful, Tapestry Garden

Hillside gardens can be complicated for a variety of reasons.  A lot of the time they are inaccessible, yet offer the opportunity for a beautiful habitat garden from which ALL life can benefit. The most important prerequisite for a successful hillside garden is Patience! Patience in the process from the conception, to installation, then to maturation. Fortunately, we have been blessed with such Clients, and the resulting gardens are providing much joy year round.

If you have hillside situation you most likely live in the ECOTONE. I love this word so much! An ecotone is a region of transition between two biological communities. Much like a forest may meet a meadow, your hillside is likely part of a mountain range, or “wild” area that meets your outdoor living spaces. Alternatively, it may be that your home is part of a constructed community, and your hillside is a product of the grading process. Either way, your hillside provides an opportunity and a challenge.

BEFORE

AFTER

Common Hillside Issues:

  • Erosion Control

  • Drainage

  • Wildlife

  • Specialized Plant Selection

  • Proper Plant Establishment

  • Sun/Shade Exposure

 

BEFORE

PROGRESS

AFTER

 

A hillside garden is an opportunity for a tapestry-esque, mosaic approach. Looking to patterns in nature as a guide, paired with a blend of multiple shrubs suited for sloped conditions is most effective for success. Climate-appropriate and native shrubs carry less water weight than succulents and can root themselves more deeply for stabilization and drought tolerance. Grasses and perennials can be used as well, provided that they are suited for the site conditions and compatible with a variety of shrub roots.

BEFORE

AFTER

Polyculture is the key. When selecting plants, ALWAYS consider habitat and biodiversity. Pollinators and other non-human being numbers are dwindling at an alarming rate. Let’s re-imagine our landscapes to be about more than us. Native plants are the first line of defense in loss of habitat and biodiversity.


WORKING WITH SLOPES CASE STUDY
A Challenging Hillside in San Mateo

The slope was covered with overgrown shrubs and trees. The biggest challenge was the hill was mostly rock, making it impractical to do much regrading. It was critical to work with the existing contours of the land. Yet, the client wanted usable space at the top of the slope, providing views of Oakland on the other side of the San Francisco Bay. In addition, the back of the property was the only means for the neighbor to bring trash cans out for pick-up or access their own yard. So, there were many practical considerations in programming the site. 

A preliminary evaluation of the property found there had an eight-foot change in elevation from the sliding glass doors of the townhome to the base of the mature Cedar tree.

Half of the change in elevation was enabled with a four-foot wood retaining wall. The client did not like how much usable space was consumed with the old wood steps. The staircase was anti-climactic, leading people to a dry, overgrown hillside.  

It was more like an overgrown park than a usable back yard. The thick shrubs gave clues as to what might be found below. The soil was dry and compacted.

 

USDA soil map classifies the site as primarily Othents with slopes ranging from 5 to 75%. These steep slopes impede horizontal development of the soil on the surface. As a result of the eroding slope, fallen leaves or needles do not sit on the surface to be broken-down by organisms such as worms, ants and beetles. Sparse shrubs do well in these conditions. 

This sample was taken from the site and illustrates the fundamental challenge of the site: Roots had no choice but the find crevices in the rocks to survive. The data from the USDA, the sample rock and a soil sample provided enough information to prepare the client for the potential issues ahead. Analysis showed that the soil had a slightly acidic composition, almost completely devoid of nutrients.

There were only a few original trees that were tagged to remain after the transformation. A majestic cedar in the corner would be the centerpiece of the design. As a result, great care was taken in both the design and construction phases to allow the roots to remain intact. 

To create usable space on the upper tier, a combination of hardscape and synthetic lawn were agreed upon with the client. Because of the radical change from what they saw every day, 3D renderings helped them see and understand the transformation.

 

The finished project respected the original wood retaining wall, but moved the steps to an area of the yard that provided more room for a lower patio.

The Cedar tree plays a prominent role in the design, casting a wide shadow over the synethetic lawn on the upper terrace.

The transition from lower patio to upper terrace took advantage of the existing slope, and the path provided an opportunity for plantings that would thrive in the underlying soil conditions. 

The soil was amended and appropriate irrigation was introduced for draught-tolerant plants. 

In the rear, the existing cinderblock wall was painted a deep blue and trellises were built to allow Star Jasmine to grow over time.

Lighting was also vital to be able to use the terrace safely in the evening. The meandering steps and the change in elevation from hardscape to synthetic lawn required thoughtful placement of lights under step treads and along the path. 

The Australian Willow on the hillside also had two uplights illuminating its delicate leaves and branches. This thin screen of trees provided some privacy from adjacent townhomes. 

Oakland is only visible from the upper tier. The vista is well worth the journey up sixteen steps and the investment in a new dreamscape. 

 

DESIGNER PLANT PICKS — Hillside Holders

APLD California Designers offer up their favorite plants for erosion control on slopes.

DESCRIPTION: Devil Mountain Wholesale Nursery. 

 
 
 

Artemisia tridentata BIG SAGEBRUSH

This dense, semi-evergreen shrub ranges in height, depending on the amount of animal grazing and available moisture. The hairy, silver-gray leaves are narrow and wedge-shaped, with 3 to 5 teeth at the tip. The new growth is most attractive, so for a more refined look, prune out old stems periodically. The clusters of tiny pale yellow flowers are fairly inconspicuous. Use big sagebrush in full sun and well-drained soil, and be careful not to over water.

DESCRIPTION: Mountain States Wholesale Nursery.

 
 
 

Eriogonum giganteum, ST. CATHERINE’S LACE

Eriogonum giganteum grows to 4’ tall x 5’ wide with attractive wooly, gray, oval leaves. It is the largest of the Buckwheats. It’s also one of the most popular nectar sources for many butterflies, especially the California Blues & Hairstreaks. The profuse clusters of small white flowers start blooming  in April and continue until Fall, when the flowers age to a rusty color. St. Catherine’s Lace requires no summer water once established & tolerates clay, though it thrives best in well-drained soil.

DESCRIPTION: The Watershed Nursery.

 
 
 

Poa colensoi BLUE TUSSOCK

We love to use deep rooted grasses. One of our new favorites is Poa colensoi. We were introduced to this grass by the grass guru John Greenlee and we have successfully tested it in our lab garden in Topanga. It is a beautiful feathery grass with a blue green cast. It not only holds the slope but will also soften the angle of a steep slope.

Sloped Landscapes Around the State

 

Meadow Magic in Topanga Canyon

The natural beauty of the landscape inspired Campion Walker to design an extensive garden using dozens of found boulders from the property to dramatically anchor the house to the gardens. 

Our team extensively terraced the extreme slope to create flat, intimate areas and drought tolerant meadows for outdoor living. We used recycled broken concrete and a modular block retaining system to create magical hidden pathways throughout this stunning four acre property.

 
 
 
 

The Montclair Project in Oakland

This backyard is on a steep slope with retaining walls of Napa Basalt. Two deck levels built with recycled Trex nestled in between makes this garden space aesthetic and usable for the whole family.

 
 
 

Hillside Country Garden in Sonoma

The landscape design called for creating a contemporary, informal and relaxing habitat garden that offers various seating areas and connects seamlessly from the house.

We developed a design that celebrates and enhances the existing, natural boulder formations, stands of silhouetted native oaks and wild meadow grasslands. Due to the challenging topography and the rugged conditions of the site, the garden is being phased in over time

This was an opportunity to create a hillside garden on a steeply sloping site and to select Mediterranean plantings that include native trees, shrubs, wildflowers and related African and Australian plants that could thrive under these conditions. The gardens were designed to be connective and an integral part of the natural diversity inherent to this particular area. The result is an ever-changing seasonal transformation of textures and colours on this amazing site.

 
 
 

The Point Loma Project

My customers purchased a property in Point Loma, San Diego with the intent to have the existing structure demolished and a new, modern home built on the site.

The lot is located high on a hill and the views of the city and the bay are beautiful. The new, three-level house has wide glass pocket doors which allow for amazing views any time of day.

There is a 31.5 feet difference in elevation from the front sidewalk to the bottom of the lot. At the front door, the elevation is 142.5 feet above sea level, and at the lowest point of the garden, the elevation is 111’. The family room doors open to the top deck, at elevation 125’. 

The homeowners’ original request was to have a lap pool outside the family room, and the original plan was drawn as such. Unfortunately, the pool contractor’s quote so exceeded the clients’ budget, plans for the pool were abandoned. Building a pool on such a steep site and with the local soil characteristics requires caissons that are anchored on bedrock for support making such a project complex and costly. 

With the pool removed from the project, the oversized patio off the family room had a large fire table and a fountain proposed, which have yet to be built. Wide stairs with raised planters on both sides, and comfortable landings direct people to the garden lower level. 

Again, the project suffered several revisions. One of the original proposals was to install a rain water tank at the lowest level of the garden to capture all the rain water that could then be used to irrigate the garden. On steep sites like this one, the city requires homeowners to keep their water away from lower neighbor’s property. Again, due to the cost, this too was also removed from the project. 

What remained was the dry creek bed that runs along the length of the lot to capture the water that would otherwise spill over the neighbor’s lot and is now being pumped out of the property. 

The design calls for a deck floating over the dry creek bed made with the old salvaged wood from the existing house, but this remains to be built.

The garden now is 3.5 years old and the plants are doing very well. Point Loma temperatures are moderated by the ocean and plants don’t have to cope with as extreme of temperatures. 

The landscape is a mixture of fruit trees, succulents, grasses, Mediterranean and Australian shrubs. Flower colors were carefully selected to reference one of the client’s cultural requests.

Ipe wood fence built on top of concrete walls follows the entire edge of the lot, and keep the customer’s dogs safe from other animals.

 
 
 

Canyon View Terrace in Bel Air

My clients were busy healthcare professionals and needed a place to relax, entertain and wash away the day’s stress. The existing forlorn concrete patio didn't do justice to the spectacular view. We created two levels of patios, an upper paved patio off the house and a lower deck below in the canyon. The capacious upper deck features a Jacuzzi with a custom-built pergola, a dining area, and a bespoke bench and fire pit. Raised planter beds break up the expanse of bluestone paving and create intimate areas while still allowing plenty of room for hosting parties and get-togethers. The lower deck and hillside are planted with California native plants, creating a veritable wildlife sanctuary.

Hillside Garden in Century City

A series of terraces are the keynote of this 6,000 square foot project; these transform a formerly unusable slope into flower-filled spaces with plenty of seating – for conversation, contemplation and dining. The overall impact is one of Mediterranean flair – warm, lively and inviting.

The hillside meadow plantings, which include pearl acacia and Japanese blueberry trees along with the  white flowering Nierembergia Jessie, are interspersed with a dining area featuring a custom-designed shade and lighting pergola, a bird-friendly water feature, a cascading waterfall and raised vegetable beds.

Incorporated in the topmost terrace is a pad for a future cottage to overlook the garden. Currently, it’s being used as the kids’ campsite, complete with an adjacent fire pit for roasting marshmallows. There’s even a pen for the family pet – a Sulcata tortoise, one of the largest tortoise species in the world.

At the front of the house, Forest Pansy redbud trees provide year-round color and a succulent garden spotlights tilt-head aloes. Nearby, rain gardens were established in the parkway. In the side yard, cisterns provide the means of harvesting 2,100 gallons of stormwater.

 
 
 

Winship Park Residence in San Anselmo

This active family wanted to create usable outdoor spaces on their steeply sloping, irregular-shaped lot. They also prioritized using natural materials and sustainable landscape techniques such as flow-through permeable pavers, rain gardens, swales, and bioretention basins. The result is a series of level play-spaces, gathering areas and vegetable beds  carved out of the hillside, all while preserving mature oak and buckeye trees. The view from the deck encompasses an artistic staircase and boulder cascade unfolding onto a meadow of low water-use grasses. Timber from a Monterey pine removed from the site was re-purposed as a hillside bench. The varying spaces and levels are connected to each other by a path that is soft underfoot, made from redwood timbers and crushed stone.

Hillside Sanctuary in San Anselmo

This vast hillside landscape, situated on a hillside in San Anselmo, Northern California, has been evolving for several years, and is the personal sanctuary of Landscape Designer Eileen Kelly, owner of Dig Your Garden Landscape Design. This sustainable, dry garden also serves as Eileen's "living laboratory" where she observes and learns from the habits, tolerances and growth of her extensive selection of plants. They include hundreds of varieties of low water, low maintenance and pollinator plants. Some appropriately nestled amongst the majestic oak trees, others that thrive in the sunny spots, and others in shadier locations. The plant palette ranges from California natives to plants from other Mediterranean regions such as South Africa and Australia. Besides this extensive variety, Eileen's collection of low-water and fire-resistant succulents has flourished extensively over the years - they are her favorites. The garden also includes a few exotics from Hawaii and other regions. ​ Several patios and sitting areas have been incorporated throughout the landscape at different levels, positioned to enjoy the natural setting and the lovely views both near and far.

Design Details:

  • Stairways, pathways and patio areas throughout the landscape offer places to pause or linger to take in the natural surroundings and views both up close and in the distance.

  • Diverse plant varieties, including CA natives, succulents and plants from other Mediterranean regions offer an abundance of pollinator plants, biodiversity and ecosystem for the birds, the bees and the butterflies. ​

  • Retaining walls constructed with Sonoma fieldstone, patios, decking and a variety of seating areas with bluestone and other natural materials.

  • ​Decomposed granite (DG) and flagstone incorporated in the pathways and patio areas.

  • Drip irrigation with a Smart Controller to efficiently monitor water uses and water conservation. Several plans, especially the succulents that have been established have been removed from the irrigation system, and watered manually, occasionally during the summer months.

 

Eichler Update in Lucas Valley (also by Eileen Kelly)

​The front and back areas surrounding this Eichler home were updated with the mid-century modern aesthetic in mind. The front landscape updates include a series of concrete walls and minimalist plant design with a massing of barrel cactus, artichoke agaves, upright thatching reeds a Blue Palm (Brahea 'Clara'), Mediterranean Fan Palms and other easy-care plants. Designed to echo the home's Eichler minimalist design. The dramatic corten steel sculpture screen, designed by artist Jesse Small, offers a striking focal point adjacent to the front doorway. ​The back landscape updates include modern concrete retaining walls and pathways accented with gravel and pebbles. The stately "Gracie Modern Arbors" offer eye-catching visual appeal and growing support for 3 grape vines along a long pathway ramp. A 4th arbor frames a stairway to the hillside with a flowering Passion Vine. The sloped hillside areas were updated with low-water and low-maintenance plants that include CA natives, other Mediterranean plants and several succulents. The narrow switch-back pathway maneuvers through the hillside and is edged with stacked stone.

Design Details:​

  • Modern concrete retaining walls and pathways compliment the home's Eichler, mid-century modern design.

  • The front landscape updated with an artful Corten Steel sculpture screen, modern retaining walls and fire-safe gravel much throughout the garden.

  • Minimalist modern planting design with architectural succulents, palms  and other low water plants echo the mid-century modern design aesthetic for curb appeal and a low-maintenance update.

  • The back landscape is highlighted by the striking circular "Gracie Modern Arbors" by TerraTrellis offering sculptural focal elements and structures for grape vines and flowering vines.

 
 

Community Connections


A REGENERATIVE RELATIONSHIP IN PASADENA

with Studio Petrichor

 
StudioP_logo_RGB_circle_hires.png
 
 

After our initial education program at Jackie Robinson Community Center with Pasadena Water and Power, we were asked to embark on a series of educational workshops on regenerative practices such as lasagna mulching, hugelkultur, rainwater harvesting, and much more.

Sheldon Reservoir is the first location we were asked to inventory and analyze for the potential use of the regenerative principles and design practices that we live by. Could we optimize local water resources, suggest ways to repurpose green waste, and ultimately harvest water, both actively and passively? Through a series of community workshops, many powerful conversations, and a design plan for the corner of Conniston Road and Arroyo Boulevard, we created the first public hugelkultur berm installations in Pasadena.

With the support of our friends, neighbors of the Reservoir, and community members who wanted to learn something new, we began this project with a series of hands-on workshops in the community. With each successive workshop, the number of participants grew. Our greatest joy comes from hearing that those participants (especially those who didn’t know each other to begin with) are now working together in their own homes and communities to employ the new techniques they have learned.

The Slope Approach

by Suzie Wiest, Regional Marketing Representative

and Nicholas Staddon, Company Spokesperson

Some months ago, I remember reading an online article about slopes. And important to remember when we are talking about slopes, they come in all shapes and sizes. Slopes can bring out the worst in us, a sense of antipathy even. So, this remembered article I was reading online was titled, “Can this garden Be Saved? I have a steep slope.” Without a doubt, the mentioned garden was a challenge, however, of course, the answer was yes. Look at some of the stunning Gardens that have been created/constructed, and in some cases “bolted” on the sides of cliffs and mountains surrounding the Mediterranean. See Monty Don’s Gardens of Italy for inspiring solutions. 

So, I asked Suzie Wiest, colleague, friend, and fellow plant nut, to give us some of her favorite choices for slopes, and this is what she came up with ... 

For slope plantings, where you’d like to provide more control of the runoff to prevent erosion, varied plantings are most effective. A mix of trees, shrubs, perennials, and groundcovers create layers of vegetation, reducing the force as rainfall touches the soil.  You can also add a layer of mulch to open areas to further reduce the surface activity. 

Your site analysis of the soil, exposure, and drainage will determine which plants will work best, but below are selections with a history of excellent performance on hillsides:

 
 

Trees with root systems that hold the soil well and take up more water

Arbutus ‘Marina’

Arbutus ‘Marina’

Arbutus ‘Marina’ — Evergreen tree with pendulous clusters of urn-shaped pink flowers in spring and fall followed by ¾” strawberry-like berries; As the bark peels away, the beautiful shiny red new bark underneath is revealed; Drought-tolerant and fire-resistant; 50 ft tall with a 40 ft. canopy; available in standard tree or multi-branch forms; Smaller shrub species of A. unedo compacta is only 7-10’ tall x 7-10’ wide.

Cercis occidentalis — Deciduous tree and a profuse bloomer with clusters of magenta pea-shaped flowers along bare stems in early spring prior to the emergence of heart-shaped leaves; Drought-tolerant and fire-resistant; 20 ft tall with a 10-20 ft canopy; available in standard tree or multi-branch forms. Hummingbirds love the blooms and birds love the seed pods. This is a favorite of mine too!

Quercus agrifolia — Evergreen tree with deep green holly-like leaves, a wide and open canopy, and massively strong trunk and branches; Drought-tolerant and fire-resistant; 40-60 ft tall with a 40-60 ft canopy; available in standard tree or natural low-branching forms. Native to coastal ranges, this is another excellent habitat tree providing shelter and food for wildlife!
