The California Water Bill, AB 1881, needs your input to update the state?EUR??,,????'?????<???????????????????????(R)?EUR??,,????'????s Model Water Efficient Landscape Ordinance. There are still parts of the bill needing overview, suggestions and, most importantly, input from landscape professionals so a more holistic approach to water conservation can be attained.
In 2004, AB 2717 passed in California. It requested the California Urban Water Conservation Council (CUWCC) convene a Landscape Task Force of public and private agencies to improve the efficiency of water use in new and existing urban irrigated landscapes in the state. The task force adopted 43 recommendations, making changes to the AB 325 of 1990 and updating the Model Local Water Efficient Landscape Ordinance.
The Water Conservation in Landscaping Act of 2006 (AB 1881, approved by governor on Sept. 28, 2006) enacted many of the recommendations of the task Force. AB 1881 required the Dept. of Water Resources (DWR) not later than Jan. 1, 2009 to update the model ordinance and requires local agencies, not later January 1, 2010 to adopt the updated model ordinance or equivalent (or it will be automatically adopted by statute). Also, the bill mandates performance standards and labeling requirements for landscape irrigation equipment, including irrigation controllers, moisture sensors, emission devices, and valves to reduce the wasteful, uneconomic, inefficient, or unnecessary consumption of energy or water.
The public and professionals can comment and provide additional information to DWR. DWR will analyze and respond to these comments. The tentative schedule for the rulemaking:
February 2008: DWR will host public hearing on the draft of the updated Model Water Efficient Landscape Ordinance to begin the 45-day public comment period.
March-April 2008: DWR will analyze and respond to the public comment and submit updated Model Water Efficient Landscape Ordinance and rulemaking package to the Office of Administrative Law (OAL).
June 2008: OAL will begin a 30-day review period on updated Model Water Efficient Landscape Ordinance and the DWR rulemaking package.
July-Dec. 2008: DWR will submit an updated Model Water Efficient Landscape Ordinance for adoption.
Jan. 2009: DWR will adopt the updated Model Water Efficient Landscape Ordinance.
Jan. 2010: Local agencies, as required by law, will adopt an updated Model Water Efficient Landscape Ordinance.
Stephanie Landregan, the chief landscape architect for the Mountains Recreation Authority and the Conservation Authority and a Southern Calif. ASLA Chapter (SCCASLA) trustee, notes that landscape architects need to give their input because they don?EUR??,,????'?????<???????????????????????(R)?EUR??,,????'????t just specify irrigation, they also plan every aspect of a site including plantings and can give the DWR a broader perspective. ?EUR??,,????'?????<?????????????????The Irrigation Association is providing needed expertise to government agencies to help bring about ways to measure water in the future, but the landscape architects are suggesting there needs to be a balance here. One doesn?EUR??,,????'?????<???????????????????????(R)?EUR??,,????'????t have to propose Draconian measures to save water.?EUR??,,????'?????<????????????????? She also notes, ?EUR??,,????'?????<?????????????????We have a sufficient amount of research into plants that require less water or survive well on grey water.?EUR??,,????'?????<?????????????????
How to participate: As we go to press in late December, we?EUR??,,????'?????<???????????????????????(R)?EUR??,,????'????re told a draft of the entire updated Model Water Efficient Landscape Ordinance will be made available to the public at www.oal.ca.gov

The draft version of Assembly Bill 1881 will go into its final version in February of 2008, and be signed into law in March. However, there are still parts of the bill needing overview, suggestions and most importantly input from landscape architects so a more holistic approach to water conservation in California can be attained. In view of the ongoing drought in this state and the large cutbacks in water usage going into effect in 2008, the bill would require adoption of water conservation performance standards regulating irrigation equipment and the installation of meters to measure water use for landscaping purposes.
Stephanie Landregan, a Southern Calif. ASLA Chapter Trustee, Angela Woodward, past president of the Southern California ASLA and CCASLA delegate, as well as Andy Bowden, SCCASLA president are putting out a call to all landscape architects to do whatever they can to open up the discussion and give the legislators needed information to achieve this goal. They feel that one of the key aspects of this ordinance is that it addresses mainly industry concerns. ?EUR??,,????'?????<?????????????????Any legislation that isn?EUR??,,????'?????<???????????????????????(R)?EUR??,,????'????t holistic tends to become overbearing. It?EUR??,,????'?????<???????????????????????(R)?EUR??,,????'????s been very hard to get individuals to call in on this since they aren?EUR??,,????'?????<???????????????????????(R)?EUR??,,????'????t necessarily affected. Landscape architects tend to be client advocates.
?EUR??,,????'?????<?????????????????Most contractors protect the trade and are protected from the consumers by the licensing bureaus. Landscape architects don?EUR??,,????'?????<???????????????????????(R)?EUR??,,????'????t just specify irrigation, they also plan every aspect of a site including plantings, so they look at it in a broader sense. When this dialogue is carried on only among government agencies, they don?EUR??,,????'?????<???????????????????????(R)?EUR??,,????'????t always know all the ramifications. Angela Woodward?EUR??,,????'?????<???????????????????????(R)?EUR??,,????'????s alarm is because the discussion is now in the 11th hour, and so landscape architects need to be ever vigilant. ?EUR??,,????'?????<?????????????????We need other landscape architects, and those whom they represent, to look at this bill and voice their concerns and suggestions,?EUR??,,????'?????<????????????????? says Ms. Woodward. ?EUR??,,????'?????<?????????????????The decisions made now will directly affect all site planning in the future.?EUR??,,????'?????<?????????????????
Adding to that, Ms. Landregan says, ?EUR??,,????'?????<?????????????????The Irrigation Association is providing needed expertise to government agencies to help bring about ways to measure water in the future, but the landscape architects are suggesting there needs to be as balance here. One doesn?EUR??,,????'?????<???????????????????????(R)?EUR??,,????'????t have to propose Draconian measures to save water. As an example, one thing that would help is to double plumb?EUR??,,????'?????<????????????????????deal with what happens to the water before it goes to the ocean. Or require all water in new housing have a cistern and use that to water the garden. That?EUR??,,????'?????<???????????????????????(R)?EUR??,,????'????s the way to affect change and deal with the realities of water. This is a holistic way of dealing with the problem.?EUR??,,????'?????<?????????????????
This will affect turf installations, often considered the evil plant material. Turf requires a lot: fertilizers and nitrates in addition to the water. But pools use as much water as lawns, and they also have chlorine and other chemicals. Grass varieties are now hybridized, so most turf installations are tough and stand up to high traffic. There aren?EUR??,,????'?????<???????????????????????(R)?EUR??,,????'????t that many plant materials that can withstand that kind of abuse. ?EUR??,,????'?????<?????????????????We have a sufficient amount of research into plants that require less water or survive well on grey water,?EUR??,,????'?????<????????????????? says Ms. Landregan. ?EUR??,,????'?????<?????????????????We need to ask people to re-look at what constitutes a beautiful landscape. Can you have a huge meadow if you?EUR??,,????'?????<???????????????????????(R)?EUR??,,????'????re not playing sports on it?
?EUR??,,????'?????<?????????????????If you try to regulate turf, you?EUR??,,????'?????<???????????????????????(R)?EUR??,,????'????ll have the same response you had with the prohibition of alcohol. Let?EUR??,,????'?????<???????????????????????(R)?EUR??,,????'????s exercise a little more reason here and figure out how keep from swinging to far in any one direction. We are trying to maintain a very prudent and reasonable approach to this drought. Husbanding our resources is great but there are other ways. It?EUR??,,????'?????<???????????????????????(R)?EUR??,,????'????s important to determine what the reality is. Try double plumbing for starters. The providers don?EUR??,,????'?????<???????????????????????(R)?EUR??,,????'????t want to talk about that because they don?EUR??,,????'?????<???????????????????????(R)?EUR??,,????'????t make money on water they don?EUR??,,????'?????<???????????????????????(R)?EUR??,,????'????t sell. It?EUR??,,????'?????<???????????????????????(R)?EUR??,,????'????s a sticky situation for them.?EUR??,,????'?????<?????????????????
Landscape architects need water to do the kind of work they do. If there is no green, many other things go out of balance. Stormwater runoff gets out of control, there is reduced carbon sequestration. The list goes on. After the fires ten years ago, the local fire departments made Draconian suggestions such as stripping the hillsides for the setbacks. That led to mudslides. Fire is part of the cycle, so the question should be, how do you deal with that cycle.?EUR??,,????'?????<?????????????????
Angela Woodward feels it is better to intervene at this point in the drafting of the new legislation. ?EUR??,,????'?????<?????????????????We have the possibility of having legislation imposed on us but we have the opportunity to become partners in this legislation.?EUR??,,????'?????<?????????????????
?EUR??,,????'?????<?????????????????During the hearings there will be other people there for small changes, but those small changes may have large consequences because they aren?EUR??,,????'?????<???????????????????????(R)?EUR??,,????'????t discussed at length,?EUR??,,????'?????<????????????????? says Ms. Landregan. ?EUR??,,????'?????<?????????????????Anyone licensed in California should be concerned. They should weigh in as well as landscape architects in other states that have dry or drought conditions they are facing such as Georgia, Texas and dry states?EUR??,,????'?????<????????????????????what have they tried? What works? Watch out for the following?EUR??,,????'?????<??????????????????????(R)???????+?, etc.?EUR??,,????'?????<?????????????????
