2. Explain the methods used to identify interested local agencies and public water systems in the affected basin(s):

Each of the six local agencies with water supply, water management and land use authority were contacted. Five of the six are working together to form a GSA and process this basin boundary revision. The 6th agency, the City of Ojai, preferred to serve on technical committees since only a small portion of the City overlies the upper Ventura River Basin and the City obtains its groundwater from the Ojai Groundwater Basin. Discussions have been held with the Public Works Director of the City of Ojai, Greg Grant and an email has been sent to him indicating the application is being made to modify the boundary. The City of Ojai sits on the Ojai Basin Groundwater Management Agency and through that agency has been working on the boundary modification for the Ojai Basin and it?s shared boundary with the Upper Ventura River basin. E-mails were sent to local mutual water companies and public water systems notifying them of the application to modify the boundary of the Upper Ventura River basin and the ongoing work to form a GSA by the participating five agencies. Letters were also sent to all well owners in and near the basin.

3. Provide information regarding the nature of consultations with affected or interested agencies. Attach and cite any copies of correspondences with local agencies and public water systems and/or any other persons or entities consulted.

H. Local Support

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

Copies of correspondence to affected agencies and water systems are in part F.3. of this submittal. In addition the five agencies forming the GSA (City of Ventura, Casitas Municipal Water District, Meiners Oaks Water District, County of Ventura and Ventura River Water District) have been actively reviewing and processing the basin modification since December 2015 as evidenced by the meeting agendas attached in Part F.4.

2. Provide a list of all affected agencies and affected systems that submitted comments and/or documents in support or opposition to the proposed boundary. The agency submitting their support or opposition for a boundary modification must provide a copy of a resolution formally adopted by the decision-making body of the affected agency or system or a letter signed by an executive officer or other official with appropriate delegated authority who represents the agency or system. Attach copies of the resolution and/or signed letter detailing the support or opposition submitted.

Affected Agencies: ? Casitas Municipal Water District ? City of San Buenaventura ? County of Ventura ? Meiners? Oaks Water District ? Ventura River Water District ? City of Ojai ? Ojai Water Conservation District ? Ojai Basin Groundwater Management Agency Affected Agencies that submitted comments: ? Comments from the County of Ventura on the draft technical report were provided and discusses at an internal meeting of the GSA formation committee on March 8, 2016. The County of Ventura?s comments have been incorporated ? The City of Ventura provided input by having their groundwater geologist, Curtis Hopkins meet several times with Jordan Kear to discuss boundary issues which were then incorporated into the proposed modification. Letters and resolutions of support will be submitted as available in the future. We have no reason to believe that letters of opposition will be forthcoming.

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

Only one rebuttal was prepared. It was in response to a water right concern voiced by Rancho Matilija MWC. See the letters dated March 7, 2016 and March 15, 2016 addressed to Rancho Matilija MWC in Section F.5. See also section II(A)(3) of Technical Memorandum by Kear Groundwater. The Response to comment letter dated May 23, 2016 addresses comments from the SWRCB, Santa Barbara Channel Keeper and Surfrider Foundation.

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.
