Water Resources


RMC is a recognized leader in water resources, integrated water supply, and recycled water planning in California, and we have been involved in strategic water supply planning since our founding in 1998.

San Diego Integrated Regional Water Management Program and Plan Update

San Diego County Water Authority

RMC has provided overall program leadership for the San Diego Integrated Regional Water Management (IRWM) program since 2007. We helped the Region establish the framework for success in developing and implementing the 2007 and 2013 IRWM Plans, and have supported the Region in continuing its eligibility to receive Proposition 84 funding from the California Department of Water Resources. Currently, RMC is providing programmatic support for the IRWM Program by managing Regional Water Management Group (RWMG), Regional Advisory Committee, and Tri-County Funding Area Coordinating Committee meetings and providing ad-hoc workgroup meeting preparation and facilitation as necessary. RMC is also working with the RWMG to conduct the regional project review, prioritization, and selection process and to support funding and public outreach, including specific outreach efforts to disadvantaged communities and Tribal Nations.

Water Conservation and Urban Water Management Plans

San Francisco Public Utilities Commission

Over the past several years, RMC has worked extensively with the Water Conservation Section of the San Francisco Public Utilities Commission (SFPUC) on water conservation-focused projects, including supporting implementation of a new city ordinance, outreach for a new grant program, and review of water audit reports. We also prepared the SFPUC Retail Conservation Plan to guide SFPUC staff in planning and implementing programs and activities that meet the conservation goals of Senate Bill 7x7 and the environmental agreements of SFPUC’s Water Supply Improvement Program. RMC continued to work with the conservation team on various tasks, such as an assessment of conservation data management software and an extensive water savings analysis for various conservation measures.

Local Groundwater Banking Feasibility Study

Eastern Municipal Water District

RMC identified water banking opportunities in the Upper Pressure and Canyon Subbasins for Eastern Municipal Water District (EMWD) and determined the facilities needed for conveyance, recharge, and extraction of banked water. The work included developing a suite of recharge and extraction scenarios that can then be pieced together to form banking alternatives to increase local supply reliability during droughts and emergencies, provide sustainable long-term supplies, and mitigate salt loading associated with recycled water use. RMC also updated EMWD’s existing MODFLOW-based groundwater model to support groundwater management projects and analyses within the EMWD water service area.

Oceanside Sustainable Groundwater Management Act (SGMA) Support

City of Oceanside

RMC is providing groundwater technical and planning support to the City of Oceanside to help address a wide variety of groundwater issues. Initial work included reviewing the California Statewide Groundwater Elevation Monitoring Plan prepared by San Diego County, and assisting the City in the formation of a Groundwater Sustainability Agency (GSA) format for the San Luis Rey Valley Groundwater Basin. The San Luis Rey Valley Groundwater Basin is a long, narrow coastal groundwater basin with a wide variety of groundwater users, including heavily urbanized areas on the west and agricultural lands and Native American tribal lands on the east.

Long-Term Water Needs and Supply Study
Amador Water Agency

RMC is developing a Long-Term Water Needs and Supply Study with Amador Water Agency (AWA) to support the study proposed by pending AB142 (Wild and Scenic River designation for the Mokelumne River above Pardee Reservoir) and to provide a planning document for AWA. Tasks include developing a long-term plan for meeting future demands and analyzing the effects of climate change on future water supply and a potential Wild and Scenic River designation on the Mokelumne River. The planning document will help AWA plan projects to ensure that the water needs of the agency’s current and future customers are met. RMC is also working with AWA staff to develop a 2015 Urban Water Management Plan that includes demand forecast and water supply analyses, climate change and water-energy assessments, and demand management measure updates.
