LIVERMOREPLANNING COMMISSION AGENDA REPORTTO:Chairperson West andMembers of the Planning CommissionPREPARED BY: Frank Guido, Associate PlannerREVIEWED BY:Paul Spence, Principal PlannerScott Lee, Senior PlannerDATE: October 19, 2010SUBJECT:Municipal Code Amendment 09-005 (amendment of WaterEfficient Landscape Ordinance)SUMMARY RECOMMENDATIONStaff recommends the Planning Commission recommend the City Council introduce anordinance amending Municipal Code, Chapter 13.25, Water Efficient Landscapes.BACKGROUNDIn July 1992, the State of California enacted the Water Conservation in Landscaping Act(Assembly Bill 325), resulting in a State Model Water Efficient Landscape Ordinance witha requirement for cities to adopt an equivalent ordinance. In December 1992, the Cityadopted an ordinance at least as effective as and closely adhering to the 1992 Statemodel, found at Chapter 13.25 of the Municipal Code, Water Efficient Landscaping(attached).In September 2006, the Governor signed Assembly Bill 1881 into law, which amendedthe original Water Conservation in Landscaping Act, including a requirement to updatethe Model Water Efficient Landscape Ordinance. In September 2009, the CaliforniaDepartment of Water Resources adopted a final updated model ordinance (Attached).The intent of the State's Model Water Efficient Landscape Ordinance is to achieveincreased landscape water use efficiency in new development.16
Since the City did not adopt an ordinance locally by this past January 1, 2010, theupdated 2009 State model is effective until such time the City adopts its own localversion. Staff has prepared the attached amended Chapter 13.25 as the City's updatedWater Efficient Landscape Ordinance.It is beneficial for the City to adopt its own amended ordinance as it can balanceflexibilities with additional sustainable practices to result in an amended ordinance that isat least as effective or more effective than the updated State Model Water EfficientOrdinance; that can cross reference other landscape related ordinances, policies, andcodes; and that is reformatted and reorganized to integrate into our Municipal Codeformat.The goal of the Water Efficient Landscape Ordinance is to save water, which in turnsaves the landowner in long-term water costs and is good for the environment. All otherjurisdictions in the State have a similar ordinance or use the State model, which createsconsistent standards for property owners and developers. This update does not changethe entitlement process for projects, the timeline for approval, nor create any new permitsor fees.In amending the City ordinance, staff consulted with Zone 7 Water Agency, CaliforniaWater Service Company, our own municipal Water Service, Livermore Area Recreationand Park District, a soil laboratory, the Irrigation Association, and a small selection ofirrigation auditors, landscape designers including Gates and Associates, architects,landscape maintenance companies, and builders to solicit input on the ordinance.PROJECT DESCRIPTION/ANALYSISSummary OverviewThe Model Water Efficient Landscape Ordinance places requirements on newlandscapes using very specific sets of requirements in landscape and irrigation design.The requirements are specific as to establishing a water budget; estimating landscapewater use from the expected water needs of selected plants; and determiningspecifications for soil management, irrigation system design, and grading.Side-by-Side Comparison DocumentAn 11-inch-by-17-inch document is provided in the packet, which consolidates andcompares side-by-side the 2009 updated State model (with modifications recommendedby StopWaste.Org as explained below); existing Municipal Code Chapter 13.25 text; andthe proposed Municipal Code Chapter 13.25 recommended by staff for adoption toimplement the updated State Model Water Efficient Ordinance.Stopwaste.org is the Alameda County Waste Management Authority and the AlamedaCounty Source Reduction and Recycling Board operating as one public agency.
