Mitigation Requirements.
1. 
The applicant shall avoid all impacts that degrade the functions and values of a critical area or areas. Unless otherwise provided in this chapter, if alteration to the critical area is unavoidable, all adverse impacts to or from critical areas and buffers resulting from a development proposal or alteration shall be mitigated using the best available science in accordance with an approved critical area report and SEPA documents, so as to result in no net loss of critical area functions and values.
2. 
Mitigation shall be in kind and on site, when possible, and sufficient to maintain the functions and values of the critical area, and to prevent risk from a hazard posed by a critical area.
3. 
Mitigation shall not be implemented until after city approval of a critical area report that includes a mitigation plan, and mitigation shall be in accordance with the provisions of the approved critical area report.
E. 
Mitigation Sequencing. Applicants shall demonstrate that all reasonable efforts have been examined with the intent to avoid and minimize impacts to critical areas. When an alteration to a critical area is proposed, such alteration shall be avoided, minimized, or compensated for in the following sequential order of preference:
1. 
Avoiding the impact altogether by not taking a certain action or parts of an action.
2. 
Minimizing impacts by limiting the degree or magnitude of the action and its implementation, by using appropriate technology, or by taking affirmative steps, such as project redesign, relocation, or timing, to avoid or reduce impacts.
3. 
Rectifying the impact to wetlands, critical aquifer recharge areas, frequently flooded areas, and habitat conservation areas by repairing, rehabilitating, or restoring the affected environment to the historical conditions or the conditions existing at the time of the initiation of the project.
4. 
Minimizing or eliminating the hazard by restoring or stabilizing the hazard area through engineered or other methods.
5. 
Reducing or eliminating the impact or hazard over time by preservation and maintenance operations during the life of the action.
6. 
Compensating for the impact to wetlands, critical aquifer recharge areas, frequently flooded areas, and habitat conservation areas by replacing, enhancing, or providing substitute resources or environments.
7. 
Monitoring the hazard or other required mitigation and taking remedial action when necessary.
8. 
Mitigation for individual actions may include a combination of the above measures.
F. 
Mitigation Plan Requirements. When mitigation is required, the applicant shall submit for approval by the city a mitigation plan as part of the critical area report. The mitigation plan shall include:
1. 
Environmental Goals and Objectives. The mitigation plan shall include a written report identifying environmental goals and objectives of the compensation proposed and including:
a. 
A description of the anticipated impacts to the critical areas and the mitigating actions proposed and the purposes of the compensation measures, including the site selection criteria; identification of compensation goals; identification of resource functions; and dates for beginning and completion of site compensation construction activities. The goals and objectives shall be related to the functions and values of the impacted critical area;
b. 
A review of the best available science supporting the proposed mitigation and a description of the report author's experience to date in restoring or creating the type of critical area proposed; and
c. 
An analysis of the likelihood of success of the compensation project.
d. 
Performance Standards. The mitigation plan shall include measurable specific criteria for evaluating whether or not the goals and objectives of the mitigation project have been successfully attained and whether or not the requirements of this chapter have been met.
e. 
Detailed Construction Plans. The mitigation plan shall include written specifications and descriptions of the mitigation proposed, such as:

vi. 
These written specifications shall be accompanied by detailed site diagrams, scaled cross-sectional drawings, topographic maps showing slope percentage and final grade elevations, and any other drawings appropriate to show construction techniques or anticipated final outcome.
G. 
Monitoring Program. The mitigation plan shall include a program for monitoring construction of the compensation project and for assessing a completed project. A protocol shall be included outlining the schedule for site monitoring (for example, monitoring shall occur in years one, three, five, and seven after site construction), and how the monitoring data will be evaluated to determine if the performance standards are being met. A monitoring report shall be submitted as needed to document milestones, successes, problems, and contingency actions of the compensation project. The compensation project shall be monitored for a period necessary to establish that performance standards have been met, but not for a period less than five years.
H. 
Contingency Plan. The mitigation plan shall include identification of potential courses of action, and any corrective measures to be taken if monitoring or evaluation indicates project performance standards are not being met.
I. 
Financial Guarantees. The mitigation plan shall include financial guarantees, if necessary, to ensure that the mitigation plan is fully implemented.

The site plan review committee shall review the request and make a written finding that the request meets or fails to meet the modification criteria as part of the underlying permit approval.
B. 
Modification Criteria. A modification may be granted only if the applicant demonstrates that the requested modification includes the best available science and gives special consideration to conservation or protection measures necessary to preserve or enhance anadromous fish habitat.
C. 
Variances from the standards of this chapter may be authorized by the city. The hearing examiner shall process the variance as provided in Chapter 18.14 YMC.
D. 
Variances from the standards of the flood damage prevention ordinance (Chapter 18.19 YMC) may be authorized as provided in YMC § 18.19.050.

2. 
The special conditions and circumstances do not result from the actions of the applicant;
3. 
A literal interpretation of the provisions of this chapter would deprive the applicant of all reasonable economic uses and privileges permitted to other properties in the vicinity and zone of the subject property under the terms of this chapter, and the variance requested is the minimum necessary to provide the applicant with such rights;
4. 
Granting the variance requested will not confer on the applicant any special privilege that is denied by this chapter to other lands, structures, or buildings under similar circumstances;
5.
