The Multibenefit Land Repurposing Program (MLRP) is a state-funded initiative to reduce reliance on overdrafted groundwater basins. The multibenefit land repurposing concept supports the strategic transition of least productive, most flood-prone irrigated land to new, lower water uses that will help reestablish sustainable groundwater supplies, and benefit landowners, adjacent communities and freshwater ecosystems.
The Greater Monterey County Integrated Regional Water Management (IRWM) Group has been awarded a $10 million grant by the California Department of Conservation through MLRP to strategically and voluntarily acquire and repurpose the least viable, most flood-prone portions of irrigated agricultural lands in the lower Salinas Valley.
IRWM is partnering with SVBGSA, the Central Coast Wetlands Group and the California Marine Sanctuary Foundation, to develop and implement this program. The Salinas Valley MLRP will support the acquisition of portions of agricultural ranches where interested landowners wish to transition farmlands to projects that increase groundwater recharge and storage, reduce flooding, and enhance water quality and base flow. Additional benefits can include habitat enhancement and public recreation opportunities. The program will focus efforts in the 180/400 Foot Aquifer, Eastside and Langley subbasins.
Recharge Suitability Mapping
The SVBGSA and MLRP partners working with Dr. Helen Dahkle and Dr. JayLee Tuil from the University of California Davis to develop a recharge suitability map and Multi-Criteria Decision Analysis (MCDA) tool. Recharge Suitability Mapping begins with identifying the local goals of groundwater recharge. A Multi-Criteria Decision Analysis (MCDA) will be an outcome of this work that will help the region prioritize suitable recharge locations.
To gather further community input for groundwater recharge in the Salinas Valley, please complete this survey to collect information about known areas of flooding and potential groundwater recharge sites. To participate in the Salinas Valley Recharge Work Group, contact SVBGSA Deputy General Manager Emily Gardner (gardnere@svbgsa.org) or indicate your interest on the survey. The Recharge Work Group will meet monthly over the next year to provide input for the creation of recharge suitability maps. The first meeting is Wednesday, Oct. 23, from 4-5 p.m. and will be virtual. Join the webinar here.
This program is funded by a Department of Conservation MLRP grant for the 180/400-Foot Aquifer, Eastside Aquifer, and Langley Area Subbasins.
The program will work with interested landowners who want to voluntarily retire portions of their irrigated lands that are more flood prone and least viable for production. Together they will develop multibenefit water resource projects that are compatible with adjacent, on-going farming operations. Optimal locations for farmland acquisition as part of this program include irrigated areas that are:
- Historic creeks and lakebeds
- Highly permeable soils
- Adjacent to waterways
- Frequently flooded
Interested landowners will be fairly compensated for these lands, which will be acquired by the program with support of four local land trusts. Lands acquired through this program will be transitioned into multibenefit projects. Example projects may include one or more of the following features:

Water scarcity and groundwater overuse are driving land use dilemmas in California, particularly in agriculture. One promising solution gaining traction is multi-benefit land repurposing, which involves transforming unproductive farmland to capture rain, floods, and diverted water for groundwater recharge.
