H. Local Support

1. Provide any evidence that sufficient information was provided to affected agencies and systems regarding the proposed boundary modification.

Letters were sent directly to the four possibly affected agencies, Phone calls were made to these agencies to verify receipt of notification.

3. Provide any evidence that rebuts any opposition to the proposed boundary modification.

Montecito Water District is not in favor of the modification because it believes that it puts them at a disadvantage with respect to managing groundwater in the Toro Canyon area because it is part of the Carpinteria Groundwater Basin (CGB). However, we are proposing that Toro Canyon sub-basin be created as a sub basin of Carpinteria where the dividing sub basin boundary is the Jurisdictional boundary between the 2 agencies. This will allow CVWD to manage the CGB within its District and allow Montecito Water to manage the Toro Canyon Sub basin if it desire to.

I. Hydrogeologic Conceptual Model

1. Principal aquifer units within requested basin.
2. Lateral boundaries of the proposed basin, including:
   1. Geologic features that significantly impede or impact groundwater flow.
   2. Aquifer characteristics that significantly impede or impact groundwater flow.
   3. Significant geologic and hydrologic features and conditions of the principle aquifer units, as appropriate, including information regarding the confined or unconfined nature of the aquifer, facies changes, truncation of units, the presence of faults or folds that impede groundwater flow, or other groundwater flow restricting features.
   4. Key surface water bodies, groundwater divides and significant recharge sources.
3. Recharge and discharge areas within the basin.
4. Definable bottom of the basin or subbasin.

The department may waive this requirement for an internal boundary modification if the requesting agency is able to demonstrate that the proposed boundary modification is unlikely to affect sustainable groundwater management.

See attached document. Added the 1974 GTC Report which show on Plate 1 that Toro Canyon Sub-unit is a sub basin of the Carpinteria Basin.
