LANDSCAPING Of those homes already built, some builders have installed the allotted turf in front yards, but TRI Pointe Homes opted to use boulders and a variety of drought-tolerant plants instead. “We thought with all of the chang- es that have happened over the last several years over water usage, cus- tomers are now more apt to make that change as long as we put thought in how it will look,” says Holly Auwinger, TRI Pointe Homes’ director of sales and marketing. For streetscapes, medians and public landscaping throughout Fol- som Ranch, the city has selected a varied plant palette of water- efficient grasses, varieties suited to the region’s Mediterranean climate like olive trees, and California natives, including large shade trees such as sycamores and oaks. Drip irrigation and stream rotating nozzles will irrigate public spaces. Rotating nozzles mimic drops of water and are 30 percent more efficient than old sprinkler systems that lose vast amounts of water due to wind, evaporation and runoff, says Zach Perras, Folsom’s municipal landscape services manager. To maximize efficiency, Folsom began using centralized irrigation controllers in 2009 that can detect leaks down to the gallon with the capability to remotely shut off the leaking valve, says Perras. In the past, fixes required a manual dispatch to a leak’s location, and in some cases, that could take up to a week. Out with the old The most important thing to remem- ber, says Saare-Edmonds, is the vast majority of the landscape in Califor- nia is already built. Old technology and sprawling lawns aren’t part of MWELO’s mandate, but they are obvious targets for improving water efficiency. “Turf grass in Sacramento needs about 4 feet of water per year on top of normal rainfall to keep it green,” says William Granger, City of Sacra- 32 comstocksmag.com | May 2020 In Folsom Ranch, the city landscaped the public areas with water-efficient grasses and trees native to California. mento’s water conservation admin- istrator. In response, rebate programs to replace turf and update irrigation controllers from preset time-based models to high-tech versions that ir- rigate based on local weather and soil conditions are common throughout California for residential and com- mercial projects. Roseville’s weather-based con- troller rebate of up to $150 has been one of its most popular programs, providing nearly $150,000 in residen- tial customer rebates since November 2016, and nearly 2 million square feet of turf has been removed through its Cash for Grass program since 2008. Replacing that with drought-tolerant plants and a drip system has saved more than 67 million gallons of water since 2008, says Bobby Alvarez, Roseville’s water conservation administrator. Similarly, the City of Sacramento’s River-Friendly Landscape Program has replaced 562,000 square feet of turf since 2014, with the highest rebate in the region at $1.50 per square foot. This year, the city will spend about $500,000 on rebates through the program — which offers turf replacement, irri- gation efficiency upgrades and smart controller rebates — roughly a third of its water conservation budget. Education and outreach pro- grams are heavily promoted to drive water efficiency and MWELO compli- ance. Roseville offers workshops on MWELO for property managers and contractors and offers year-round landscaping workshops for residents. Folsom offers similar programming for residents, including eco-friendly landscape education — one which Balics presented in 2019 — and Water Wise House Calls, free in-person assessments of residents’ water use. There’s no shortage of online water-wise guidance, lists of low- water plants, free water-efficient landscape templates and apps, like Dropcountr, used in Folsom, which monitors personal water use and sends leak alerts in real time. Resources help bridge the gap in education, so those who aren’t aware of MWELO — often homeowners who want to renovate — are informed of best practices that align with the water efficient ordinance.
