in 1984 – “Agency Act”

  • Our Job: Achieve Sustainable

Groundwater Resources

  • Multi-jurisdictional: City of

Watsonville, parts of Santa Cruz, Monterey and San Benito Counties

Sustainable Groundwater Management Act

  • The Sustainable

Groundwater Management Act or SGMA (September 2014) requires that high priority, critically overdrafted groundwater basins such as the Pajaro Valley be brought into balance by 2040.

  • If not, the State Water

Resources Control Board may intervene and may impose pumping restrictions.

Grants to Fund Water Supply Projects

  • Approximately half of

constructed project costs were funded through grants

  • PV Water projects, which

focus on water conservation and optimize use of local resources, are competitive for federal and state funding

Existing Water Supply Facil ilities to Reduce Overdraft & Seawater In Intrusion

  • Harkins Slough Facility

– Managed Aquifer Recharge & Recovery – Stream flow diversion – 8,000 AF recharged since 2002

  • Recycled Water Facility

– 4,000 AFY irrigation season capacity – Drought tolerant supply – Reduces discharge of secondary effluent to marine sanctuary

  • Coastal Distribution System

– Over 21 miles of water conveyance pipeline

  • Blend Supplies

Paja jaro Valley Hydrologic Model

  • A hydrologic flow model to guide

water management decisions

  • Designed to reproduce all natural &

human components of the hydrologic system, and related climatic factors

  • Management & planning tool
  • Offset in water budget: 12,100 AFY

Basin Management Planning Update

In 2010 the PV Water Board established an Ad Hoc Basin Management Plan Committee to… “investigate all practical projects and programs that contribute to the efficient and economical management

  • f existing and supplemental water

supplies” and “serve as an advisory committee to the PV Water Board so that Board decisions are fully informed and affected and guided by the community’s interests”.

BMP Update Obje jectives

  • Prevent seawater intrusion, long-term groundwater
  • verdraft, land subsidence, and water quality

degradation;

  • Manage existing and supplemental water supplies to

control overdraft and to provide for present and future water needs;

  • Create a reliable, long-term water supply, which has

been identified as an important cornerstone of the long-term economic vitality of the Pajaro Valley;

  • Develop water conservation programs; and
  • Recommend a program that is cost effective and

environmentally sound.

Recharge Net Metering Pilo ilot Program

  • Provides financial incentive to landowners to capture and

recharge surface water runoff (> 100 AF)

  • Will improve aquifer conditions (quantity & quality)
  • Diversifies groundwater recharge opportunities
  • 5-year pilot program
  • Collaborative effort between the PV Water, UC Santa

Cruz, Resource Conservation District of Santa Cruz, & Landowners

  • Cost of Service Analysis (required per Proposition 218)

performed in two phases:

Phase II: Rate Calculation & Implementation

Calculation of rate structure to support

  • ngoing and forecasted expenditures

Phase I: Rate Setting Methodology & Development

Evaluation of available cost recovery mechanisms (i.e., Uniform Rates, Tiered Rates, Assessments)

Summary

  • Stakeholder involvement through committees has been a

critical component of recent successes.

  • Providing tools to committee members has been very useful in

improving understanding and building trust.

  • Public outreach to the broader community is also very
  • important. Board meetings tend to not be well attended.
