Gardeners’ Guild is obsessed with weather.  Well – we are a landscape contracting company and we must adapt on a moment’s notice to rain, high winds and unseasonable heat or frost.  We also stay on top of long term forecasting because our clients depend on us to help them manage their resources.

I personally am obsessed with it. One, I need to since our San Francisco Bay Area readers are.  And two, I find it fascinating. 

Our recent heavy rain seems to suggest a wet winter.  Yes! More is predicted this weekend.  Will our reservoirs be full by next spring?  An article in the San Jose Mercury News and the most recent post on weatherwest.com has some indications based on weather forecast modeling.

We are still officially in a drought, however.  If you look at the map above you can see why.

However, there are parts of the Bay Area that have been downgraded to just “abnormally dry”.  These counties are Sonoma, Marin, San Francisco, San Mateo and Santa Cruz, Western Napa and Western Santa Clara. Unfortunately, Santa Clara County, as well as Contra Costa, Alameda, Solano, San Benito and Monterey remain officially in a drought. 

Water experts say that it would take a “very wet winter – all across the state – or perhaps two wet years – to end the drought statewide.

Forecasting from weatherwest.com post on October 25th described conflicting information that obscures any long term rainy season forecast. In his article, Daniel Swain says that climate modeling suggests a few possibilities:

  • Another Pacific high pressure ridge again
  • A warm winter
  • A possibility that Northern California’s will enjoy more precipitation than Southern California

Swain, in his last post, suggested that a La Niña was less likely. But his October article says we are “edging back to a La Niña-like” event. His evidence is cool water in the eastern Pacific and a warming trend for the tropical West Pacific.  This, he says is linked to an unusually high pressure system.

I wish could pass on better news.  And, of course we don’t know for sure.  That’s kind of frustrating. So continue rain dances, visualizing and we will continue offering advice on water conservation and irrigation that saves water.

The California drought map shown above represents the state as of November 10th. (2016). 

Some additional facts about the rain in October:
The October drenching was the wettest since 1921
San Francisco ‘s rainfall was 209% of average
But, the soil was dry and therefore the rain did not increase water levels as much as you would think.

SFPUC

Local Regulations

  • 10% voluntary reduction in water use compared to 2013 – all SFPUC customers. 
  • 25% reduction of landscape watering lifted as of July 1, 2016
  • Revert wastewater flow factors back to their original adjustments, effective July 1, 2016.

Prohibited water activities (State Requirements)

  • Watering outdoor landscapes that causes runoff to sidewalks, streets, and hardscapes
  • Using a hose without a shut-off nozzle
  • No washing of driveways, sidewalks or hardscape; except as needed for health and safety or to meet City of San Francisco standards
  • Using drinking water for soil compaction, dust control, or other non-essential construction purposes if non-potable water is available.
  • Watering outdoor landscapes with potable water during and within forty-eight (48) hours after a rain event.
  • Watering with potable water of ornamental turf on public street medians; 
  • Inefficient irrigation of landscapes outside of new homes and buildings
  • Using drinking water in non-recirculating fountains or decorative water devices. 

SFPUC Watering Recommendations

For a typical San Francisco property, reducing watering to once or twice a week, and/or the amount time that watering occurs, will help ensure efficient water use while keeping plants alive.

For steeply sloped areas, watering should be done in multiple start times to avoid runoff. Watering for 5 minutes, turn off for an hour, and then water again for another 5 minutes results in better absorption than 10 minutes straight. Consider replacing grass or high water use plants with drought-tolerant species or converting to drip irrigation.

If you are a Property Manager, you are likely knee-deep in budget season

Remember that landscaping can increase the value of a house from 5% to 12.7%.  On a $400,000 home 5.5% is $22,000; 12.7% adds $50,800.*  Conversely, a degraded or disorganized collection of plants detracts from a home or commercial building’s value.  Bob Vila says that the biggest mistake homeowners make is a lack of a coherent plan. Similar for commercial properties and residential communities.

With the long term in mind, make sure you have these 4 categories covered in your landscape budget for 2017.

Landscape management:

  • Allow for materials cost increases for items such plants, including annual color; mulch.
  • Mulch replenishment is important. It has a neat appearance and helps soil hold water.
  • Annual color replacement
  • Allowance for IPM (Integrated Pest Management) treatments

Irrigation upgrades and repairs**

  • An irrigation system installed more than ten years ago may be wasting water and costing you money. Ensuring efficiency may mean replacing and repairing.
  • Smart (or weather based) irrigation controllers can also save up to 30% off your water bill.
  • Converting from spray to drip is something to consider for your budget.
  • State of the art precision spray nozzles can improve spray irrigation efficiency and save water too.

Large Tree Care

  • Routine pruning and fertilization are important for the health of your trees – an important part of your asset. Older trees may need more maintenance.  With proper care your trees will last many years.
  • A tree care plan will alleviate the stress of emergency tree work needs.

Landscape Improvements**

  • Turf care includes aeration and soil building or possibly overseeding.
  • Because of California’s ongoing drought and San Francisco Bay Area restrictions, you may consider converting turf to drought tolerant plants.
  • Consider converting annual color to more permanent perennial plant material.
  • The useful lifespan for large shrubs or small trees is approximately 7 to 10 years. When plants are past their useful lifespan they should be replaced with new plant material.

Delosperma Firespinner2
Firespinner Iceplant “Delosperma”

There are a number of resources for firesafe landscaping.  This post summarizes some of the best practices, plus links for more information.

Tip 1: Create Defensible Space

Defensible space is the clearance created between a structure and the grass, shrubs, trees or any natural area that surrounds it. State of California says it is a property’s “front line of defense against wildfire”.

It is needed to slow or stop the spread of wildfire and also protects firefighters.

There are two zones; the first is 30 feet, the second, 100 feet.

Zone 1

  • Essentials are to remove dead plants, leaves, grass, weeds and woodpiles.
  • Remove branches that hang over your roof.
  • Keep tree branches a minimum of 10 feet from each other
  • Separate patio furniture and equipment that could catch fire

Zone 2

  • Keep grass height to be maximum of 4”
  • Vertical spacing between grass, shrubs and trees
  • Horizontal spacing between shrubs and trees.

Tip 2: Landscape Design

Note: no plant is fire-proof, but there are plants more fire resistant.

In addition to plant selection, factors such as size, height, density and spacing between plants are very important.

Marin County Firesafe promotes the use of masonry, gravel, stepping stone or stone walls and decorative rock.

Mulch does help conserve moisture. However, it will burn. Do not use it in garden beds near home our outbuildings. Note: stringy mulches ignite and burn more rapidly.

Tip 3: Landscape Maintenance

  • Regular irrigation is important. Plants with high moisture content will be less flammable. We must walk the fine line with enough, but not too much water. Dead and woody branches can more easily catch fire.
  • Control invasive weeds
  • Prune dead branches within tree canopy
  • Thin out dense shrubs to reduce fuel load
  • Clean up of dead branches
  • Selectively remove trees and shrubs to improve spatial separation

Sources include: State of California, County of Marin and Western Arborist

The State Water Resources Control Board, responding to pressure to relax water rationing from June 2015, is allowing water districts to set their own conservation targets based a projected additional three-year dry spell. 
An important caveat: the state will have oversight and each district will be required to submit a monthly water use report.  And, if projections are found to be unrealistic, there could be a return to state regulations.

Permanent Restrictions

  • Hosing down driveways or sidewalks
  • Washing cars without shut off nozzle
  • Using non recirculated water in decorative fountains
  • Causing runoff when watering lawns or within 48 hours of rainfall
  • Irrigating turf on public medians

California May 2016 Drought Map

The water picture for Northern California is quite different from Central and Southern California.  Sections of these areas remain parched.  The US drought monitor reports that 90 percent of the state remains in a drought.  See map. In fact, there are some communities whose supplies of water are limited.

Emphasis on Long Term Planning

The message was a sobering reflection on California’s future reality, in that it is likely to include more frequent drought years.  The Governor underscored the need for effective long term drought planning.
Felicia Marcus, chairwoman of the state’s Water Resources Control Board, said Our emphasis is on conservation as a way of life in California.” She also stated that we no longer have the luxury of taking our precious water for granted.
