Construction of Olympians Park is complete! The 3.4-acre park contains an amphitheater, dog park, event lawn, picnic areas, sports courts and a jogging loop. The park was designed as a flexible outdoor space for the community and provides much needed green space in a dense urban area.

Jason in our Santa Rosa office has finished the great backyard project! The deck was finished this late fall. It was way more work than he and Matthew anticipated, but it turned out better than they could have hoped for. With the deck project finished they could finally install the last planting and install a pea gravel patio. They are happy to be done with nail guns and wheelbarrows of gravel!

Quadrigans are sheltering in place and working from home like so many of you out there. We are also taking the extra time at home to do some gardening. Emily, from our Santa Rosa office, moved into her new house recently and is at the beginning stages of her front yard paradise. Where does a garden start? With the soil of course! Dealing with clay soil, she decided to employ sheet mulching, with the idea that there is less digging, tilling and chemicals needed for a successful garden bed. It’s a compost in place idea that leaves the soil ecosystem intact, smothers weeds, holds more water and builds great soil over time. Let the worms do all the work! Stay tuned for garden photos next year.

Construction of Olympians Park continues! The old wood-mill hopper has undergone a makeover; a new mural, by artist Jose Di Gregorio, adorns the structure. The asphalt bike and running trail that runs underneath the hopper is beginning to take shape. In the bottom image, contractors are laying bricks, salvaged from the site for reuse, along the face of the new amphitheater stage.

Let’s face it, we like to geek out occasionally and this month we did just that! Brett traveled to the annual ASLA Conference on Landscape Architecture in San Diego. The annual meeting is a great opportunity to reenergize the spirit and reconnect with colleagues. It is also an incredible opportunity to explore works in landscape architecture throughout the region while getting to know a new city and its people. While in San Diego, Brett visited Balboa Park in which The Botanical Building and Lily Pond are located, pictured left.

It happens every year, right when the grasses start really looking gorgeous—whamm cut back to nothing but dead looking bunches. Please leave them in their glorious, amazing fall splendor! Deciduous grasses do best when you cut them back in late winter, right before the spring flush. And please, please NEVER cut back evergreen grasses.
Just a little friendly public service announcement from a concerned citizen…

The Quadriga team got a well-deserved day in the sun visiting di Rosa Center for Contemporary Art in Napa and Larson Family Winery near Sonoma. Di Rosa opened to the public in 1997, has multiple galleries and a sculpture meadow that the public can peruse on the weekends. Our team especially liked the large figurative ceramic sculptures by Viola Frey. Almost an entire gallery was dedicated to more than 100 pieces of her work, and blew us away with her use of bright colors and sheer size of ceramic pieces.
We followed the gallery with a picnic lunch and wine tasting at Larson Family Winery, topping the day with a cornhole tournament proudly won by John and Jessica. We highly recommend both locations for a fun day out and about in Northern California.

Jason in our Santa Rosa office has been putting his design knowledge to use in his own backyard, building a 15-foot by 40-foot redwood deck. Each weekend for the past month Jason, his husband Matthew, and assorted friends and family have tackled a different task. Starting with laying out the deck in string line, affixing brackets an existing concrete patio, excavating for piers, and then pouring concrete footings. This past weekend they installed the pressure treated beams and finally the deck is beginning to take shape. To be continued…..

Construction of Olympians Park begins June 2019! The park is central to The Mill at Broadway, an urban community located along the Broadway corridor. This sawdust hopper, pictured left, is a relic of Setzer Forest Products, the company which previously occupied the site. The Hopper is repurposed as an iconic representation of the site’s history and as a focal point at the core of the community. It is slated to receive a makeover, including a new paint job and lighting.

Water conservation and finding the right plant for the right place is at the heart of what we do here at Quadriga. This month we were fortunate to learn from Village Nurseries and Mountain States Nursery about low water and heat-tolerant alternatives to some of the more moderate water use plants we love. One interesting alternative we learned about from Village was Sporobolus wrightii (Giant Sacaton) which is a great substitute for the more invasive Cortaderia (pampas grass). This grass received high ratings for its appearance during its lowest irrigation treatment during the 2015-2017 UC Landscape Plant Irrigation Trials.

Two years in and our rain water garden has really grown in at Wright Charter School! Native sedges, yarrow, penstemon, and red bud have tripled in size around a swale which directs rain water back into the earth, rather than a storm drain. This educational feature, along with a rain water collection tank, was designed to smartly use storm water and help educate children about the importance of wise water use in our dry California climate.

Who needs 2 acres of high-water turf when you can have a low-water, native, and (let’s face it) more interesting grassland? Napa Health and Human Services’ revamped frontage landscape is nearing completion and the planting is really taking off!

As stewards of the land we try to be aware of products that are harmful to the environment. Ipe is a popular deck material but it’s contribution to deforestation has us investigating these alternative products: Accoya, Moso Bamboo, and Black Locust. We hope to use one of these environmentally sensitive products for WEST, a mixed-use housing project we are working on in West Sacramento.

Bill Mastick has retired, completing a period of transition that began in 2015. We will miss his exuberant laugh, his vast vocabulary, his leadership and, most importantly, his dog Carl. We are excited to see what he will do next! Over the past three years, management and leadership responsibilities have been assumed by Principals Christine Talbot and John Suesens. They will continue to guide Quadriga’s growth, development and relationships in the years to come. Congratulations, Bill!
