LANDSCAPING hen Bernadette Balics opened Eco- logical Landscape Design in Davis in 2001, she was one of just a few business- es in the Capital Region that designed landscapes according to eco-friendly and water-efficient principles. Today, she has lots of competitors, and there’s plenty of business for everyone. Balics’ industry is at the forefront of a major shift in how California is responding to a limited water supply as demands increase and climate change brings more extreme weather events like droughts that further destabilize the water sup- ply. Californians use ap- proximately 8-million-acre feet of water annually for urban use, according to a report from the Public Pol- icy Institute of California. Of that, nearly half goes to irrigating landscapes, more than 1.3 trillion gallons of water (because of changes in landscaping and in- creased awareness, that is down approximately 20 percent from just 10 years ago). In January, a draft of Gov. Gavin Newsom’s Water Resilience Portfolio was released, citing more than 100 recommendations to shore up California’s long-term water resiliency. The plan identifies orna- mental landscapes and turf as a target for reducing water use and looks to simplify the state’s Model Water Efficient Landscape Ordinance to help reach its goals. In its simplest terms, the ordinance requires residential and commercial projects with new landscapes more than 500 square feet and renovated landscapes more than 2,500 square feet to comply with a water budget using drought-tolerant plants irrigated with efficient technology such as smart controllers and drip irrigation. The water budget is calculated based on local weather, the plants used and the size of the landscape. It’s submitted as part of a project’s landscape plans to be reviewed, enforced and approved by cities, just like other building codes. Drive through new developments across the Capital Region like East Sacramento’s McKinley Village or Folsom’s Folsom Ranch — the larg- Building Standards Code — have com- plicated an already complex and diffi- cult regulation, resulting in fragmented adoption, implementation and manda- tory reporting throughout the state. Compounding the issue, MWELO’s current version is limited to the design and build of a landscape where the calculated water budget is theoretical, but doesn’t address maintenance where actual water effi- ciency comes into play. Additionally, it doesn’t address traditional landscapes with sprawling swaths of grass installed before MWELO limited turf to no more than 25 percent of the landscape. While compliance with regulations like MWELO es- tablishes a baseline for water efficiency, it’s part of a much larger conversation about how we sustain the planet. The ordinance presents an opportunity to shift the way we think about what an eco-friendly landscape can do when we move beyond com- pliance toward practices that conserve all natural resources and maximize water effi- ciency. That’s important for California as it seeks to strike a balance for an uncertain water supply among agricul- ture, the environment and cities, while it simultaneously addresses human activity that is shifting the climate. “A large part of that is the lack of knowledge. People just don’t have the special training to understand the landscape. And there’s still a lot of people in the landscape industry who don’t understand the ordinance or that they have to comply with a water budget.” 30 comstocksmag.com | May 2020 JULIE SAARE-EDMONDS SENIOR ENVIRONMENTAL SCIENTIST, DEPARTMENT OF WATER RESOURCES est master-planned community in the foothills in decades — or those popping up in Roseville, Rocklin, Elk Grove and Woodland, and one will see a distinctly different landscape than ones installed just 10 years ago. Low- to medium-water-use plants are surrounded by bark mulch with little or no grass, irrigated primarily with a drip system. That’s MWELO in action. But it’s not that simple. While versions of MWELO have been in place since 1992, updates — required every three years by the California Green Addressing barriers In 2009, the Department of Water Re- sources mandated the state’s roughly 540 land-use agencies — cities and counties — adopt the model ordinance, or implement stronger measures, and enforce it locally. That’s been a challenge. Julie Saare-Edmonds, senior environmental scientist at the DWR’s Water Use Efficiency Branch, says only about 26 percent of agencies submitted their mandatory reports document- ing implementation efforts in 2017,
