19.07.110 Critical area study1.
This section is included in your selections.

A. A critical area study shall be required when a development proposal will result in an alteration to one or more critical areas or critical area buffers or when required to determine the potential impact to a critical area.

B. The critical area study shall be in the form of a written report supported by graphic information prepared by a qualified professional using guidance based on the best available science consistent with the standards in Chapter 365-195 WAC and shall contain the following items, as applicable to adequately evaluate the proposal, proposed alterations, and mitigation:

1. Disclosure of the presence of critical areas, including a delineation and type or category of critical area, on the development proposal site and any mapped or identifiable critical areas on or off site within the distance equal to the largest potential required buffer applicable to the development proposal area on the applicant’s property;

2. A topographic and boundary survey;

3. A statement specifying the accuracy of the report and all assumptions made and relied upon;

4. A description of the methodologies used to conduct the critical area study, including references;

5. A scale map of the development proposal site;

6. Photographic records of the site before the proposed alteration occurs;

7. An assessment of the probable effects to critical areas and associated buffers, including impacts caused by the development proposal and associated alterations to the subject property and impacts to other properties and any critical areas or buffers located on them resulting from the development of the site and the proposed development;

8. A description of mitigation sequencing implementation described in MICC 19.07.100 including steps taken to avoid and minimize critical areas impacts to the greatest extent feasible;

9. Detailed studies, as required by this chapter, for individual critical area types in order to ensure critical area protection;

10. Assessment of potential impacts that may occur on adjacent sites, such as sedimentation or erosion, where applicable; and

11. A post-design memorandum prepared by a qualified professional confirming that the proposed improvements comply with the design recommendations.

C. The critical area study requirement may be waived or modified if the applicant demonstrates that the development proposal will not have an impact on the critical area or its buffer in a manner contrary to the purposes and requirements of this chapter.

1Code reviser’s note: Ord. 19C-06 repeals the former MICC 19.07.110, Shoreline master program. However, that ordinance is pending Department of Ecology approval, so that section is still in effect. The text of 19.07.110, Shoreline master program, is on file in the office of the city clerk.
