Alpine County Board of Supervisors Resolution No. R2003-18 Attachment B Page 1 MITIGATION MONITORING PROGRAM INTRODUCTION This document describes the County Mitigation Monitoring Program (MMP) for the 2001 Kirkwood Specific Plan (Specific Plan), the Mountain Master Development Plan (MMDP), and the wastewater treatment plant upgrade (WWTP). [Kirkwood Recirculated Revised Final Environmental Impact Report (Alpine County et al, 2002) (FEIR)]. Pursuant to 14 C.C.R. § 15367, Alpine County was the lead agency for the Environmental Impact Report (EIR) that analyzed the impacts of the Specific Plan, the MMDP, and the WWTP. Since the FEIR’s certification, KMR has requested that Alpine County approve the Specific Plan as modified by Alternative E in the FEIR. Alternative E reduces the Specific Plan’s proposed development in Kirkwood North, Ski-In/Ski-Out, as well as the overall population growth in the valley. [FEIR at page 5-11]. As a result, the Specific Plan, as modified by Alternative E, would result in less environmental impacts than would the Specific Plan as it was first defined in the FEIR’s “Proposed Project.” [FEIR at pages 5-37 to 5-39]. Given KMR’s request that Alpine County consider approval of the Specific Plan as modified by Alternative E, the Proposed Project that is the subject of this MMP includes: The 2001 Kirkwood Specific Plan as modified by Alternative E of the FEIR; The Mountain Master Development Plan (MMDP); and The wastewater treatment plant upgrade (WWTP). The MMP is presented pursuant to California Public Resources Code § 21081.6(a), which requires public agencies to “adopt a reporting and monitoring program for the changes made to the project or conditions of project approval adopted in order to mitigate or avoid significant effects on the environment.” [See also 14 C.C.R. § 15091(d)]. A MMP is required for the Proposed Project because the EIR has identified potentially significant adverse impacts, and mitigation measures have been identified to mitigate or avoid those impacts. The numbering of the individual mitigation measures follows the numbering sequence as found in the Kirkwood Recirculated Revised Final Environmental Impact Report (FEIR, Alpine County et al, 2002). All revisions to mitigation measures resulting from public comment and staff review of prior drafts of the environmental document have been incorporated into this MMP. The MMP includes, and identifies, those mitigation measures that Alpine County found to be within the responsibility and jurisdiction of a public agency other than Alpine County, and that can and should be adopted by such other agency. 14 C.C.R. § 15091(a)(3). In accordance with state statutes, adoption of the MMP will occur prior to, or concurrently with, adoption of the Proposed Project for which the program has been developed. ---PAGE BREAK--- Alpine County Board of Supervisors Resolution No. R2003-18 Attachment B Page 2 PURPOSE AND STRUCTURE OF THE MMP An MMP is intended to serve the following functions: • Ensure that mitigation measures are implemented. • Provide feedback to agency staff and decision makers about the effectiveness of the mitigation measures. • Provide learning opportunities for improving mitigation measures on future projects. • Identify the need for enforcement action before irreversible environmental damage occurs. The table that follows this introductory text is the body of the MMP. For each mitigation measure required as a condition of project adoption, the following information is provided in the table. Impact and Mitigation Measures The MMP follows the organization of the FEIR’s impact analysis. Action Required For every mitigation measure, one or more actions are described. These are the heart of the MMP as they define the means for implementing mitigation measures and, in many cases, the criteria for determining whether measures have been implemented. In some cases, the mitigation measure itself provides adequate detail, so the information under Action Required is merely a summary. In other cases, substantial new information regarding how a measure is to be implemented is provided. Timing Requirement Each action must take place during or prior to some element of the Proposed Project or project development or approval. Some measures will be applied through the entire term of the Proposed Project, some will be applied at specific junctures, and others will be necessary only if certain circumstances arise. Responsible Party This is the entity responsible for actual, on-the-ground implementation of the mitigation measure. In most instances, the “project proponent” is identified as the Responsible Party. This could be KMR for activities they undertake at the community level, KMPUD for the WWTP, or individual developers for specific residential of commercial projects. In some cases, the Responsible Party is a governmental entity or agency creation of an ordinance). Review Authority This is the agency or individual with oversight of the mitigation measures’ implementation. The Review Authority will oversee the Responsible Party’s efforts to implement the mitigation measure and determine whether the effort is adequate to meet the intent of the mitigation measure. Because the Tri County Technical Advisory Committee (TC-TAC) will play the central oversight role in insuring that mitigation measures are implemented and effective (see Overall Mitigation Monitoring/Project Review below), the TC- TAC is most often identified as the Review Authority. For measures involving the ski area special use ---PAGE BREAK--- Alpine County Board of Supervisors Resolution No. R2003-18 Attachment B Page 3 permit area or other National Forest System resources, the Forest Service is often listed with TC-TAC. In a few instances, other state or federal agencies will have an active oversight role and are also listed as Review Authorities. Enforcement Authority This is the entity, typically a regulatory agency, with the legal authority to assure that the required mitigation measure has been applied and that the intended reduction in impacts has occurred. This is typically not TC-TAC, because of that committee’s advisory role. Where enforcement will ultimately be a county function, the appropriate county official or office is identified. For impacts to National Forest System resources, the Forest Service is included in this role. In instances where other state or federal agencies have enforcement authority for a particular measure, they are also identified. OVERALL MITIGATION MONITORING/PROJECT REVIEW Biennial Review Every 2 years KMR or its successor will provide a report on development progress to date, and projected development for the next 2 years. The report will contain information on the following: • Status of total development within the resort. • Construction and phasing of necessary infrastructure and utilities. • Status of any required off-site improvements necessary to support development of the resort. • Compliance with required mitigation monitoring and conditions of approval for the Proposed Project. The report will be reviewed at a regular meeting of the TC-TAC. Copies of the report, along with the comments of TC-TAC, will be forwarded to the planning commissions and boards of supervisors of all three counties and will be made available to the public. KMR will provide a summary of the report to all property owners within the resort. Biennial Fiscal Impact Analysis Review: A. KMR has provided the County with an analysis entitled the Kirkwood Mountain Resort Kirkwood Specific Plan Fiscal Impact Analysis and dated April 2003 (“2003 Fiscal Impact Analysis”). The 2003 Fiscal Impact Analysis describes the fiscal impacts on Alpine County of the development contemplated under the Kirkwood Specific Plan. The 2003 Fiscal Impact Analysis indicates that for the budget year 2001/02, Kirkwood produced a surplus of County revenues over the costs of County Services in the approximate amount of $714,588.00. [2003 Fiscal Impact Analysis page ii, Table ES-19]. The 2003 Fiscal Impact Analysis further indicates that, at complete build-out of the Specific Plan, the County’s annual revenues from future development under the Specific Plan will exceed the expected County costs of services by $2,024,181.00. [April 2003 Fiscal Impact Analysis page iv, Table ES-2]. ---PAGE BREAK--- Alpine County Board of Supervisors Resolution No. R2003-18 Attachment B Page 4 B. During the required biennial review of the project impacts, KMR and the County will evaluate the cost of the County's services resulting from development under the revised Specific Plan. C. If the conclusions provided in that evaluation differ by more than thirty (30%) from the corresponding conclusions of the 2003 Fiscal Impact Analysis, then KMR shall submit a revised fiscal report for County review and approval. If the evaluation indicates that the County's actual cost of service exceeds the projected annual revenues from taxes, fees and assessments plus any cumulative surplus of revenues, then the County and KMR agree to jointly evaluate mechanisms for increasing County revenues or reducing County expenses so that there is not a net negative number. If after approval of the revised Specific Plan, actual annual County expenses exceed taxes, fees and assessments plus any cumulative surplus of revenues, the County shall have no obligation to approve further development under the revised Specific Plan. D. KMR and the County shall resolve any controversy or claim related to this Fiscal Review Requirement pursuant to this provision, which shall survive the expiration or termination of the Fiscal Review Requirement. In the event of a dispute involving the cost or level of County services provided, KMR and the County shall provide each other documentation justifying their respective positions. (ii) KMR and the County shall first seek to resolve any dispute by negotiations between authorized representatives. (iii) If the dispute has not been resolved by negotiations within thirty days of it having been raised by either KMR or the County, either KMR or the County may initiate mediation of the dispute by sending the other entity a written request that the dispute be mediated. (iv) Should the mediation not result in a settlement of any or all issues, either KMR or the County may request declaratory relief as to the responsibilities of the parties in a court of competent jurisdiction. The prevailing party in any such action shall be entitled to recover its reasonable attorney’s fees, expert witness fees, and costs. 10-Year Review During the tenth year following approval of the Proposed Project, KMR or its successor will retain a qualified consultant to review the development for compliance with the mitigation requirements in this MMP and any other conditions of approval of the Proposed Project. The selection of the consultant will be mutually agreed to by TC-TAC. The consultant will identify any shortcomings and make recommendations for adjustment to mitigation measures or conditions of approval to overcome those shortcomings. Additionally, the consultant will identify any new circumstances or unanticipated impacts that were not foreseen when the FEIR was certified and the Proposed Project approved. The consultant will recommend whether or not a supplemental EIR may be necessary. The consultant’s report and recommendations will be reviewed at a regular meeting of TC-TAC. Prior to the meeting, the report will be made available to the public. TC-TAC will consider the report and forward recommendations, along with the consultant’s report, to the planning commissions and boards of supervisors of all three counties. It will be clear that a decision regarding preparation of a supplemental EIR will be made by the lead agency subject to the requirements of CEQA. Further action, including additional mitigation measures, adjustments ---PAGE BREAK--- Alpine County Board of Supervisors Resolution No. R2003-18 Attachment B Page 5 to the Proposed Project and additional conditions of approval may be considered and imposed in accordance with the requirements of CEQA and other applicable laws, ordinances, and regulations. ---PAGE BREAK--- Alpine County Board of Supervisors Resolution No. R2003-18 Attachment B Page 6 KIRKWOOD SPECIFIC PLAN MITIGATION MONITORING PLAN Impact and Mitigation Measure Action Required Timing Requirement Responsible Party Review Authority Enforcement Authority 4.1 GEOLOGY, SOILS, AND GEOLOGIC HAZARDS Soil disturbance and erosion.
