The nature and intensity of the proposed development.
2. 
An analysis of the effect of the proposed development, activity or land use change upon the wildlife species and habitat, including critical freshwater and saltwater habitats, identified for protection.
3. 
A discussion on how the applicant proposes to mitigate any adverse impacts to wild-life habitats created by the proposed development. (See Sections 22.700.105, Wetland delineation report, and 22.700.110, Wetland mitigation plan/report).
D. 
Examples of mitigation measures to be included in the HMP report include, but are not limited to:
1. 
Establishment of buffer zones. When applicable, the order of sequence for buffer reductions shall be as follows:

b. 
Reduction of the overall buffer area by no more than twenty-five percent of the area required under the standard buffer requirement,
c. 
Enhancement of existing degraded buffer area and replanting of the disturbed buffer area,
d. 
The use of alternative on-site wastewater systems in order to minimize site clearing,
e. 
Infiltration of stormwater where soils permit,
f. 
Retention of existing native vegetation on other portions of the site in order to offset habitat loss from buffer reduction;
2. 
Preservation of native plants and trees essential to maintaining habitat function;
3. 
Limitation of access to habitat areas;
4.

Fees may be collected for this plan as specified in community development fee schedule. Where this plan is required for the protection of an eagle habitat, the USFWS Bald Eagle Management Guidelines and Conservation Plan for the Pacific Region shall be utilized.
(Ord. 598 (2021) § 4 (Appx. 1), 2021)
A. 
Whenever development is proposed in a geologically hazardous area or where required in this program, or when the department determines that additional soils and slope analysis is appropriate on a particular site, the applicant is required to submit a geotechnical or geological report that evaluates the surface and subsurface soil conditions on the site.
B. 
Qualifications.
1. 
Geotechnical reports shall be prepared by a geotechnical engineer.
2. 
Geological reports may be prepared by a licensed geologist or geotechnical engineer.
C. 
General Provisions. Report recommendations for earthwork, clearing or siting structures in geologically hazardous areas shall be based on existing site conditions rather than measures that have not yet been successfully approved, designed, or constructed (e.g., slope recontouring, slope retaining walls, vegetation improvements, bulkheads, etc.). Shoreline stabilization and retaining walls may only be utilized as an engineering solution where it can be demonstrated that:
1. 
An existing residential structure or other permitted existing public or private structures or public facilities such as roads or highways, cannot be safely maintained without such measures;
2. 
Other nonstructural methods of beach stabilization have been considered and determined infeasible; and
3. 
The resulting stabilization structure is the minimum necessary to provide stability for the existing structure and appurtenances. Minor repair activities on existing permitted structures (e.g., those that do not involve design modifications, changes in structure location, and/or demolition or abandonment of failed structure and replacement with new structure) are not subject to the following project submittal standards.
D. 
Geological Report Submittal Standards. A geological report is required for site development proposals that involve development activity or the installation of structures within a geologically hazardous area or shoreline setbacks, or as otherwise required pursuant to Chapters 19.300 and 19.400 as incorporated herein by reference, but do not involve or require engineering design recommendations. The following minimum information is required:
1. 
Site information regarding the Kitsap County shoreline environment designation and critical areas designations that affect site features;
2. 
Description of surface and subsurface conditions, including ground materials, vegetation, surface drainage, groundwater, and a preliminary geologic hazard assessment which includes the locations of structures and the identification of the slope and/or coastal processes occurring at the site and factors that contribute to them;
3. 
Review of available site information, literature, and mapping;
4. 
Detailed description of slope and other topographic features;
5. 
Conceptual siting of structures and general recommendations, which include methods and practices that avoid and/or reduce slope and shore impacts. Minimum recommendations should include upland and slope drainage control, groundwater control, site vegetation management, and erosion control.
E. 
Geotechnical Report Submittal Standards. A geotechnical report is required when the department or a geological report determines that a site development proposal requires additional site information such as engineering design recommendations, slope stability analysis, subsurface exploration and testing, coastal process analyses, or construction recommendations. Depending on the level of activity proposed, the report will either be a more limited geotechnical slope evaluation report or a full geotechnical design investigation report as described below.
1. 
Geotechnical Slope Evaluation Report. A geotechnical slope evaluation report is required when slope stability analyses are confined to addressing only existing surface and/or drainage conditions, including the relationship of natural and constructed slope features to proposed changes in environmental conditions such as drainage, vegetation removal and slope geometry. The following minimum information is required:
a. 
All the information required under subsection (D) of this section (Geological Report Submittal Standards);
b. 
Subsurface data, exploration logs, and testing data, when required by the geotechnical engineer;
c. 
Estimated (or surveyed) site plan with ground surface profiles and typical cross-sections;
d. 
Relative location of ordinary high water (OHW) on the surface profile and cross-sections, which includes mean higher high water (MHHW) for the site location, where applicable;
e. 
Soil strength parameters;
f. 
Stability analysis of existing site;
g. 
Analysis of the relationship of vegetation and slope stability; and
h. 
Conceptual site development plans and cross-sections.
2. 
Geotechnical Design Investigation Report. A geotechnical design investigation report is required for site development activities that propose design and construction measures at the slope crest, face and/or toe. If a designed structure does not impact slope stability or coastal processes, the report will not be required to perform all items listed under this section, as long as each item is addressed and the report details why a particular item does not apply. The report shall include all items considered necessary by the engineer to fully address the engineering design requirements of the site. The following minimum information is required:
a. 
All the information required under subsection (E)(1) of this section (Geotechnical Slope Evaluation Report);
b. 
Geotechnical requirements and measures to reduce risks;
c. 
Geotechnical criteria used for any designs including all critical dimensions, lateral earth pressures, soil bearing pressures, location and limits of structures on or near the slope, maximum constructed slope angles, minimum soil reinforcement embedment, soil compaction requirements, and structure heights;
d. 
Temporary construction slope stability recommendations and analysis of proposed final site stability measures;
e. 
Required construction specifications and construction monitoring procedures;
f. 
Revegetation and surface and ground-water management requirements;
g. 
Evaluation of erosion potential, recommendations for erosion avoidance and any proposed mitigation measures;
h. 
Detailed tabulation of all basic geotechnical engineering test results pertinent to design and construction, and when required for clarification, detailed examples of tests conducted for the project; and
i. 
Information outlined in the geotechnical design investigation report site evaluation checklist (see subsection (G) of this section).
F. 
Additional Requirements for Sites in Geologically Hazardous Areas. When a project site is located within a landslide-prone geologically hazardous area, as classified in Section 19.400.425, the following additional project submittal requirements shall apply:
1. 
Erosion Control Information. An evaluation of the erosion potential on the site during and after construction is required. The evaluation shall include recommendations for mitigation, including retention of vegetative buffers and a revegetation program. The geotechnical engineer shall provide a statement identifying buffer areas at the top or toe of a slope based on geotechnical site constraints and the impacts of proposed construction methods on the erosion potential of the slope.
2. 
Seismic Information. The geotechnical engineer shall submit a statement that the design criteria consider the one-in-one-hundred-year seismic event (an earthquake ground motion that has a forty percent probability of exceedance in fifty years). Calculations of soil bearing capacity, general soil stability, and wall lateral earth pressures shall be adjusted to reflect a one-in-one-hundred-year seismic event and the structural plans for the project shall be reviewed by the geotechnical engineer for consistency with these design criteria. Analysis for the one-in-one-hundred-year seismic event shall be based on a near crustal event having an assumed magnitude of six and one-half and occurring directly below the site. Based on regional studies performed by others, the department will allow the use of the following minimum general values of horizontal peak ground accelerations for this event:
a = 0.2g for fill, alluvial soils.
a = 0.17g for till, firm glaciated soils.
a = 0.15g for rock.
The appropriateness of the above accelerations shall be confirmed by the geotechnical engineer based on the actual site characteristics. Reduction in the above values may be considered when supported by the appropriate analytical evidence. Slope stability, lateral pressures, and liquefaction of the site shall be assessed by using subsurface soil, rock and groundwater conditions, as well as the seismic parameters discussed above.
3. 
Recommendations on Relative Site Stability. The geotechnical engineer shall make recommendations as to which portion of the site is the least prone to instability and the preferred location of the structure. The limits of any area proposed for grading activity shall be identified.
4. 
Construction Season Limitation. In general, no excavation will be permitted in landslide-prone geologically hazardous areas during the typically wet winter months. When excavation is proposed, including the maintenance of open temporary slopes, between October 1st and April 30th, technical analysis shall be provided to ensure that no environmental harm, threat to adjacent properties, or safety issues would result. In addition, recommendations for temporary erosion control and shoring/mitigating measures shall be provided. The technical analysis shall consist of plans showing mitigation techniques and a technical memorandum from the geotechnical engineer.
5. 
Revisions to Geotechnical Report. Further recommendations shall be provided by the geotechnical engineer should there be additions or exceptions to the original recommendations based on the plans, site conditions, or other supporting data. If the geotechnical engineer who revises the plans and specifications is not the same engineer who prepared the geotechnical report, the new engineer shall, in a letter to the department, express his or her agreement or disagreement with the recommendations in the geotechnical report and state whether the plans and specifications conform to his or her recommendations.
6. 
Plan and Specification Review. The geotechnical engineer shall submit a statement that in his or her judgment, the plans and specifications (if prepared by others) conform to the recommendations in the geotechnical report and that all portions of the site which are disturbed or impacted by the proposed development have appropriate measures or specifications that permit construction to occur while addressing slope stability so that the work does not create additional risk. The statement shall also indicate whether or not a relative gain in slope stability will be achieved after construction is complete.
7. 
Construction Inspection. A final inspection report shall be provided by the geotechnical engineer stating that construction has or has not implemented the design recommendations of the geotechnical report, and evaluating of any deviation from the design recommendations.
G. 
Geotechnical Design Investigation Report – Site Evaluation Checklist. The following are general report guidelines for geotechnical design investigation reports. The following guidelines are not intended to be all-inclusive. It is the responsibility of the geotechnical engineer to address all factors, which in their opinion are relevant to the site. The checklist information shall be included as part of the geotechnical design investigation report. All items listed below must be addressed in the report. Information shall be provided for those items which are not relevant to a given site to demonstrate why the items are not applicable.

Applications for development or operations with underground storage of petroleum products will be processed using the appropriate procedure as specified in existing Kitsap County ordinances.
E. 
Analysis for a specific parcel(s), using the criteria outlined below, will be employed to confirm if the soils present require a recharge area designation. Data collection will include, at a minimum, six soil logs to a depth of ten feet (or to a depth four feet below the lowest proposed excavation point, whichever is greater) for each acre in the parcel(s) being evaluated. At least one well, two hundred feet or greater in depth with an adequate drilling report, must be available within one mile. The associated data shall be analyzed and included in the hydrogeologic report to determine the presence of highly permeable soils with the recharge area designation. For development proposals within aquifer recharge areas of concern, the hydrogeological report may be based on a quarter-quarter section basis where the number of wells within a half-mile radius is thirty-six or more. To facilitate computer analysis, the evaluation may be done on a quarter-quarter section basis using the quarter-quarter section in which a parcel of interest is located and all the surrounding quarter-quarter sections, in place of the half-mile circle.
(Ord. 598 (2021) § 4 (Appx. 1), 2021)
A. 
Introduction. Cumulative impacts result when the effects of an action are added to or interact with other effects in a particular place and within a particular time. It is the combination of these effects, and any resulting environmental degradation, that should be the focus of cumulative impact analysis. While impacts can be differentiated by direct, indirect, and cumulative, the concept of cumulative impacts takes into account all disturbances. Thus, the cumulative impacts of an action can be viewed as the total effects on a resource, ecosystem, or human community, i.e., the sum of this action to all other activities affecting that resource no matter what entity is taking the actions.
Unlike direct and indirect impact assessments, the cumulative impact assessment entails a more extensive and broader review of possible effects. It should be recognized that while no “cookbook” approach to cumulative impacts analysis exists, a general approach is described here.
B. 
Approach.
1. 
Considerations.
a. 
The proximity of the projects to other similar projects either geographically or temporally;
b. 
The probability of actions affecting the same environmental system, especially systems that are susceptible to development pressures; and
c. 
The likelihood that the project will lead to a wide range of effects or lead to a number of associated projects.
2. 
Resources and Ecosystem Components. To determine which resources are cumulatively affected, consider:
a. 
Whether the resource is especially vulnerable to incremental effects;
b. 
Whether the proposed action is one of several similar actions in the same geographical area;
c. 
Whether other activities in the area have similar effects on the resource;
d. 
Whether the effects have been historically significant for this resource; and
e. 
Whether other analyses in the area have identified a cumulative effects concern.
3. 
Geographic Boundaries and Time Period. An appropriate spatial scope of the cumulative impacts analysis is determined by:
a. 
Identifying a geographic area that includes resources potentially affected by the proposed project;
b. 
Extending that area, where necessary, to include resources affected by the combined impacts of the project and other actions; and
c. 
Combining ecological boundaries with political boundaries when necessary to adequately delineate the assessment area.
4. 
Past, Present and Reasonably Foreseeable Future Actions. Consider:
a. 
Whether the environment has been degraded, and if so, to what extent;
b. 
Whether ongoing activities in the area are causing impacts; and
c. 
The trends of activities and impacts in the area.
5. 
Describing the Condition of the Environment. Describe:
a. 
How the environment to be affected by the project functions naturally and whether it has been significantly degraded;
b. 
The specific characteristics of the affected environment and the extent of change, if any, that has occurred in that environment; and
c. 
The natural condition of the environment or, if that is not available, some modified, but ecologically sustainable, condition to serve as a benchmark.
6. 
Using Thresholds to Assess Resource Degradation. Thresholds should be practical, scientifically defensible, and fit the scale of the analysis. They may be either numeric standards, qualitative standards or based on desired management goals.
(Ord. 598 (2021) § 4 (Appx. 1), 2021)
A. 
Any over-water structure that will exceed a length of fifteen percent of the shore-to-shore distance shall require a navigation study.
B. 
A navigation study, at a minimum, shall include:
1. 
Demonstration of the need for a structure longer than fifteen percent of the shore-to-shore distance;
2. 
The proposed structure length and its percent of the shore-to-shore distance;
3. 
Location of the nearest parks or public access points, especially those that provide haul-outs to recreational, scientific or tribal boaters/paddlers;
4. 
Number of days for which the tides (low and high) would render navigation under or around the proposed structure to be hazardous for paddlers or motorized boaters (if allowed in the water body); and
5. 
Any measures that could be taken to minimize impacts to navigation.
(Ord. 598 (2021) § 4 (Appx. 1), 2021)
When required, a shoreline mitigation plan shall include the following:
A. 
Requested biological and/or habitat surveys (Section 22.700.145) to determine the existing site condition.
B. 
A description of the existing conditions, functions and processes.
C. 
A plan for mitigating any development impacts so that the proposed development does not result in a net loss of those identified conditions, functions and processes.
D. 
The mitigation must be completed or installed prior to development activity, unless demonstrated infeasible.
E. 
The mitigation will require annual progress updates until the department determines the mitigation is successful.
F. 
Mitigation done as part of a shoreline mitigation plan shall be subject to all other mitigation requirements of the program.
(Ord. 598 (2021) § 4 (Appx. 1), 2021)
