10.1 Local Water Planning

Transcription

1 10 COORDINATION WITH EXISTING LOCAL/REGIONAL PLANS Each of the IRWM agencies plan and execute both short-term capital improvement programs and long-term plans and management programs. It is their plans, reports, studies, and programs along with certain regional plans, documents, and programs that provide the foundation for the IRWM Plan and present a coordinated, integrated approach. In addition to the numerous planning documents listed in this section, key planning documents are also included as Appendices to this Plan, such as Appendix G: Salt and Nutrient Management Plan, Appendix H: Floodplain Management Plan, Appendix I: Groundwater Management and Facility Plan, and Appendix J: Climate Change Analysis Local Water Planning It is the intent of this IRWM Plan to be congruent with local plans and to include current, relevant elements of local water planning and water management issues common to multiple local entities in the Region. The IRWM planning does not replace or supersede local planning, but incorporates local planning elements. The IRWM Group shall coordinate water management activities and information with local water planners and stakeholders through IRWM Group meetings, workshops, outreach activities, and and website updates. Additionally, IRWM Plan strategies and priority projects are planned and implemented through extensive coordination and cooperation between Group members. Planning activities addressed in this teaming process include: Groundwater Management Urban Water Management Water Supply Management Wastewater Management Watershed Management City and County General Planning Low Impact Development Flood Protection Ecological Resource Management Salt and Salinity Management Emergency Response/Disaster Plans Many existing plans, including Water Supply Master Plans, Groundwater Management Plans, Watershed Management Plans, Water Reliability Assessments, Recycled Water Studies, Desalinization Feasibility Studies, and Long-Range Plans contain proposed 10-1

2 projects that are instrumental in meeting the goals and objectives of the Region. Projects within local and regional plans and studies have been incorporated into this IRWM Plan, and will continue to be implemented in coordination with those plans. Although this IRWM Plan addresses Region-wide water management issues, local plans may present efforts or goals specific to a local water or natural resource. In the case that a stated goal or activity of a local plan conflicts with, or is inconsistent with, this IRWM Plan the IRWM Group shall organize meetings with the local governments or agencies to identify inconsistencies between the plans and resolve any issues. As IRWM planning develops and progresses, the dynamic relationships between local plans and the IRWM Plan will continue to consider and incorporate: Consistency and coordination regarding local plan content and the IRWM Plan content, Relevant, accurate, and current local plan information and references of which the IRWM Plan is based, Water management issues and climate change adaptation and mitigation strategies from local plans into the IRWM Plan, and Limits, levels, management tools or criteria relevant to water management in local plans that are applicable to the IRWM Plan. Both local plans and this IRWM Plan will periodically be updated to reflect effective, integrated, and consistent water planning and management as the Region faces increasing challenges in managing its water supply due to climate change, increasing water demand as population increases, and uncertainty regarding the availability of water from the Sacramento-San Joaquin Delta and other sources. When the IRWM Plan is updated, the relevancy of the plans included here will be reviewed and the most updated or recent plans will be included. Table 10-1, Existing Local and Regional Plans, Documents, and s, demonstrates the multitude of plans and projects that the South Orange County IRWM Plan integrates into regional planning. 10-2

Therefore, by approaching the Region on a watershed basis, the availability of local water resources 10-8

9 can be clearly outlined. To meet the requirements of Sections J and L of the municipal National Pollution Discharge Elimination System (NPDES) Stormwater Permits issued jointly to the cities within the County, the Orange County Flood Control District and the, watershed chapters developed for the County s DAMP are updated annually. The chapters and their respective updates are developed by the Permittees of each watershed. The Permittees are comprised of each city within the geographic boundaries of the watershed in addition to the and the Orange County Flood Control District. A representation of coordination with an existing plan is the Southern California Comprehensive Water Reclamation and Reuse Study (SCCWRRS). This 6-year study evaluated the feasibility of maximizing the beneficial uses of recycled water through regional collaborative programs. The Study covered a 6 county area in southern California, included over 7,300 demand points and all wastewater supplies in its data bases. The SCCWRRS was a partnership between the U.S. Bureau of Reclamation and eight cost sharing partners. Three phases of the study have been completed: compilation of data to analyze the optimum use of reclaimed water; development of preliminary designs and costs for specific projects; and identification of short and longterm projects. Many of the findings, recommendations, and proposed projects were considered within this IRWM Plan. The IRWM Plan will continue to be coordinated with this Study and other planning documents that already have studied and considered many of the key factors within the IRWM Plan. The Projects in this IRWM Plan reflect effective, integrated, and consistent water planning and management as the Region faces increasing challenges in managing its water supply due to climate change, increasing water demand as population increases, and uncertainty regarding the availability of water from the Sacramento-San Joaquin Delta and other sources. The Projects integrate watershed management plans. The Projects also support implementation of DAMP and SCCWRRS, as well as local plans. The Smart Water Landscape Project implements MWDOC s Urban Water Management Plan, Runoff Reduction Studies, and other long range plans. The Shadow Rock Detention Basin Project assists in the municipal National Pollution Discharge Elimination System (NPDES) Stormwater Permits issued jointly to the cities within the County, the Orange County Flood Control District and the. In addition, the Trabuco Canyon Water District signed an MOU with the Trabuco Highlands Community Association (THCA) for the Project operation to coordinate land and water management. The Rockledge Ocean Protection Project implements the Laguna Beach s Sewer Capital Improvement Plan, as well as multiple plans associated with the Laguna Beach State Marine Conservation Area (SMCA) Local Land Use Planning Land use decisions and water management decisions are often under the purview of different agencies, yet the resources each agency manages are inextricably linked. Often, the relationship among these agencies is characterized as reactive in that one agency must act to accommodate a decision the other agency has made. Early communication is vital in changing the relationship from reactive to proactive. Local land use planning, regional water issues, and water management objectives are closely 10-9

10 related due to the overlap of issues present within the watershed management planning. Figure 10-1 shows land use for the region 78. Local land use planning and water supply planning are coordinated through a patchwork of existing State laws and policies. Regional wholesalers such as MWD base their water supply plans of regional growth projections developed by regional planning agencies. Urban Water Management Plans, as established by the Urban Water Management Planning Act, must be prepared by large water purveyors (3,000 acre-feet/year or 3,000 customers), must evaluate water supplies and demands over a 20-year period, and must be updated every five years. South OC WMA water districts routinely submit their UWMP to the state every 5 years and must consider land use in their water supply and demand projections. 78 Southern California Association of Governments 2008 Land Use Data 10-10

12 Municipal water conservation efforts and landscaping programs integrate land use and water planning. For example, MWDOC s South OC WSL Project integrates water management with land use planning by proposing to implement an aggressive landscape improvement program on publicly owned and other commercial landscapes properties. This requires careful coordination between the participating City s and land/property owners. Operation and maintenance measures are also considerations for determining the appropriate locations for removing non-functional turf, upgrading antiquated irrigation timers to weather-based self-adjusting irrigation timers, and converting high-volume spray irrigation to low-volume irrigation. The Water Smart Landscape Project will also reduce maintenance costs on both the landscape itself as well as asphalt street material (over 84 acres of existing landscape are targeted for improvement through this program). Senate Bills 610 and 221 (2001) were enacted by the State legislature to improve the coordination between land use planning and development and available long-term water supplies. These laws are intended to require assessment and verification, respectively, of water supply reliability prior to approval of specified large land use projects. SB 610 applies during the CEQA process, and SB 221 applies to subdivision approvals. Both laws require a demonstration of sufficient reliable 20-year water supplies to serve both the proposed project and other water users relying on the same water supplies, during normal, single dry, and multiple dry years. They require the water agencies responsible for water resource planning to work with the local land use agencies that often have little control over water supplies. In addition to some changes in the Urban Water Management Planning Act since the last UWMPs were submitted in 2005, Governor Schwarzenegger in his 20x2020 Plan determined that for California to continue to have enough water support its growing population, it needs to reduce the amount of water each person uses per day (Per Capita Daily Consumption, which is measured in gallons per capita per day). This reduction of 20 percent per capita use by the year 2020 is supported by legislation passed in November 2009 SB x 7_7 (Steinberg). Other State laws and policies play a more indirect role in coordinating land use and water supply planning. The OPR General Plan Guidelines encourages local governments to plan at a watershed level for better regional self-sufficiency and to consider adopting an optional water element in General Plans to address water supply and other water-related impacts of land use policies. Local agency formation commissions (LAFCOs) are regional agencies that approve local agency boundary changes; they perform municipal service reviews to evaluate how all services, including water, are delivered to developing areas of the state. 79 Local land use plans have assisted in the development of this IRWM Plan. In this way the IRWM Plan is consistent with and reflects projects that are linked to land use planning in the Region. Refer to Figure 10-1 for the Land Use Map. Plans and information that have contributed to the IRWM Plan include city General Plans - Land 79 California Water Plan Update 2009, Vol. 2, Chapter 24 Land Use Planning and Management 10-12

13 Use Elements, Storm Water Elements, and Water/Wastewater Elements; County of Orange Land Use Planning documents; and Southern California Association of Governments (SCAG) land use data. The General Plan also played a major role in evaluating projects for consistency with planned land use. Much of the land use data has assisted in the regional planning and projections of water demands, water use classifications, infrastructure master planning, and reliability planning into the future. The IRWM Plan will continue the essential link to local land use plans, and can be considered a planning document in return for many local land use plans. An exchange of knowledge, ideas, and expertise between land use and water resource managers in the Region is essential to improving planning efforts between the IRWM Plan and local land use plans. A high level of communication is necessary to ensure water managers and land use planners make informed, collaborative water management decisions on a region-wide basis. To facilitate communication and coordination between water managers and land use managers in the Region, the IRWM Group includes local land use planners and agencies in meeting notices and informational s regarding the IRWM planning process. Land use planners are encouraged to attend South Orange County IRWM Group meetings. Managing multiple water demands throughout the Region, adapting water management systems to the effects of climate change, and potentially offsetting climate change impacts to the water supply can be improved by a collaborative and informed relationship between land use and water planners. Future opportunities for a better working relationship between water managers and land use decision makers include: Coordinate changes to the IRWM Plan with land use planners Improve communication mechanisms for interacting with the land use planning community Consider future forums, policies, and projects that could improve water management efforts, such as regular meetings between water managers and land use planners Consider existing and planned future land use designation when planning and managing various water supply and water quality projects. Apply the Ahwahnee Principles for Resource Efficient Land Use to advocate a more proactive relationship between land use and water management 80. Utilize current land use and water issues and identify planning strategies which may be implemented, or explored in the future through the IRWM process
