There was enough rainfall over the winter season for the California State Water Resources Control Board to modify their Emergency Water Conservation Regulations. On May 18th, 2016 it was adopted to recognize persistent yet less severe drought conditions throughout California and require local agencies to develop and implement conservation standards based on their particular circumstances.
The new standard requires local water agencies to ensure a three-year supply of water assuming three more dry years in the future like the ones we experienced from 2012 to 2015. Water agencies that would face shortages under three additional dry years are required to meet a conservation standard equal to the amount of the shortage.
Makes sense to us who have long been on the band wagon to conserve water both indoors and out. Our local water districts have both kept their water conserving restrictions in place. Since up to 70% of summer water use comes from landscape irrigation it?s a good place to start.
Both San Lorenzo Valley Water District– http://www.slvwd.com – and Scotts Valley Water Districts – http://www.svwd.org – offer many tips and incentives to conserve water. Using less water-intensive plants, there are lists on their websites of drought-tolerant plants and water smart grasses, as well as replacing lawns with drought tolerant or native plants and/or permeable landscape materials such as mulch, decomposed granite, permeable pavers are just some of the ways you can keep your yard looking beautiful and also be water efficient.
Rebate programs from local water districts offer several landscaping credits including sprinkler to drip irrigation conversion credit, weather-based irrigation controller credit, replacement credit for converting an existing lawn to water-wise grasses, greywater laundry-to-landscape irrigation conversion, rainwater catchment and downspout diversion. Both districts have guidelines and procedures to apply for the rebates on their websites.
Additional rebates from the California State Department of Water Resources are available to single-family residences for lawn replacement. This rebate application is separate from the local water District?s and you need to go online and follow the state?s guidelines in order to be eligible for these additional funds. See www.SaveOurWaterRebates.com for the details.
The fun part begins when you redesign the area where you took out the lawn or modify the plantings in other beds to include same water use plants. It doesn?t make much sense if you have some plants that require more water than the others in the same bed. You have to water to the highest water use plant to keep everybody happy.
Hydrozoning is the practice of clustering together plants with similar water requirements to conserve water. A planting design where plants are grouped by water needs improves efficiency and plant health by avoiding overwatering or underwatering. As you move farther away from the water source your plantings should require less water.
Now is the time before it gets hot to look at your irrigation system, plant choices and rebate options to save water and money and recharge our aquifers.
