Sweetwater Authority Infrastructure Investment Secures Safe And Reliable Water For Its Customers

Chula Vista, Calif. – At its June 13 meeting, the Sweetwater Authority Governing Board adopted its preliminary budget for the 2018-2019 fiscal year and accepted and filed a Five-Year Water Rate study. Over the next five years, the Authority will invest $72 million in water quality improvements, a new 36-inch transmission main pipeline, and necessary safety work to the Sweetwater and Loveland Dams.

Why California’s Limit On Residential Water Use Doesn’t Really Exist

California has always been America’s leader on environmental policy, and water is no exception. So it was hardly surprising when the state made headlines across the nation in early June with a new policy on residential water use: Californians will be limited to 55 gallons per person per day for their indoor water needs. The rule is apparently the first of its kind in the nation. But lost in the excitement is the fact that water agencies have no way to measure how much water their customers use indoors.

Deferred Maintenance On City Storm Water System May Lead To Emergencies

A city of San Diego analysis delivered to the City Council’s Audit Committee Wednesday found that Storm Water Division infrastructure faces the largest deferred maintenance backlog of any asset type in the city amid chronically insufficient funding. Continued deficits could lead to more emergencies and an inability to meet water quality requirements, Principal Senior Performance Auditor Andy Hanau told the committee. The Storm Water Division is projected to need $891 million to keep up with infrastructure needs and water quality standards over the next five years. Only $433 million in funding has been identified, however, leaving a gap of about $458 million.

Nestlé Granted Three-Year Permit To Keep Piping Water Out Of California National Forest

The U.S. Forest Service has granted Nestle a new three-year permit to continue operating its bottled water pipeline in the San Bernardino National Forest. The agency announced the decision Wednesday, saying the permit has been offered to the company “with measures to improve the watershed’s health” along Strawberry Creek. The Forest Service took up the matter in 2015 after a Desert Sun investigation revealed Nestlé was piping water out of the mountains under a permit that listed 1988 as the expiration date.

Southern California’s Coastal Communities Could Lose 130 Feet Of Cliffs This Century As Sea Levels Rise

It’s not just beaches and sand that are disappearing as the ocean pushes inland. Sea level rise is also eating away at California’s coastal cliffs. The question is by how much, as Californians have heavily developed and continue to build along the edge of the Pacific. Scientists are now one step closer to projecting how these bluffs will fare this century — and the outlook is sobering. In Southern California, cliffs could recede more than 130 feet by the year 2100 if the sea keeps rising, according to a new study led by the U.S. Geological Survey.

The Right Way to Remove Your Lawn

If you have made the decision to replace your thirsty, water-guzzling grass, you need to plan your grass removal process carefully to ensure you leave healthy living soil ready for new landscaping in its place.  

Here’s how to do it: 

First, keep your grass moist until you remove it. Don’t withhold irrigation and let it turn brown as it dies off. Healthy microbes in your soil will die off along with the lawn. You want to work with those microbes to help create healthy soil for your new plants. It’s also a lot easier to remove fresh, moist grass than to try and pry out dead dry grass and weeds in hard dry soil.  

Keep your soil microbes healthy to support your new landscaping

Along the same lines, don’t “solarize” your landscaping in the effort to remove your lawn. Solarizing is sometimes used as a way to remove grass with chemicals. It uses a covering such as a heavy black plastic tarp to broil the lawn at high temperatures using sunlight and kill it. But that process kills everything, including healthy microbes you need for healthy soil. Yes, you can replace them with compost, but you will need to invest in a lot of compost to restore the good microbes after you’ve removed the grass by solarizing. 

 Solarizing also backfires because sterilized soil is ideal for weeks. The moment you remove the plastic, opportunistic weeds will move in fast to try and take over the ground. It isn’t because you failed to kill the weed seeds in the soil. New weeds can arrive in a flash, and there is nothing to prevent them taking over.  

Avoid compacting or tilling your soil when removing old turf

Avoid compacting your soil. If you use heavy equipment to remove your old turf, the weight of the equipment will compact the soil underneath. Try to minimize the use of heavy equipment and use walk-behind equipment with hand tools where possible, reserving the use of a tractor or scraper only where necessary.  

Avoid tilling your soil. Tilling soil breaks up and kills your soil microbes. Without the microbes, you’re guaranteed to have those weeds pop up for a long time until new soil microbes develop.  

When removing your grass, protect your trees. If you want to preserve your healthy trees while removing your lawn, you need to be careful with their roots. Don’t use any heavy equipment to remove turf around your trees. Avoid the entire area under the canopy of the tree’s branches. Tree root structures extend all the way out to the drip line at the edge of the leaves. Keep your trees well-watered during the removal process to help minimize root shock.  

Guard against shock to trees from reduced irrigation

When your new sustainable landscaping is installed, your previously existing trees may go into shock when irrigation is reduced overall in your garden. After all, this is one of the reasons for removing your lawn. Pay special attention to keeping the trees watered during the first year after your grass is removed, even if you remove the surrounding original irrigation.  

A good way to hand-water trees is to punch holes in a five-gallon plastic bucket. Fill the bucket, set it down at the edge of the tree canopy, and let the water slowly seep into the ground. Repeat the process three to four times to water your beautiful mature trees. This mimics the natural rainfall Mother Nature provides.
