Hallmark was contracted by the Delta-Mendota Subbasin (DM Subbasin) to provide Project Management services to the agency, including all meeting facilitation for the Board of Directors, project controls, financial management, budget development and tracking, schedule management, consultant management, contract management, public outreach, and coordination of grant administration and reporting. The DM Subbasin was established in the 2003 Revision to Bulletin 118; a publication by the California Department of Water Resources which establishes Subbasin and Basin boundaries for the local management of groundwater. In July of 2023, the 23 DM Subbasin GSAs signed a Memorandum of Agreement to form one single GSP and in February of 2026, the DM Subbasin GSAs formed a Joint Powers Authority (JPA) to implement the single GSP to meet groundwater sustainability goals under the Sustainable Groundwater Management Act (SGMA).
The DM Subbasin JPA is governed by a 7-member Board of Directors and includes representatives from the Aliso Water District GSA Group, Central Delta-Mendota GSA Group, Farmers Water District GSA Group, Fresno County Areas A and B GSA Group, Grassland Water District GSA Group, Northern Delta-Mendota GSA Group, and the San Joaquin River Exchange Contractors GSA Group.
Results: The Hallmark Group managed the development of the Delta-Mendota Subbasin JPA and is the Project Manager supporting the implementation of the DM Subbasin GSP.
