New development that would require shoreline stabilization which causes significant impacts to adjacent or downstream properties shall be avoided or minimized.
D. 
When new, enlarged or replacement shoreline modifications for stabilization are proposed, the feasibility of nonstructural shoreline stabilization measures shall be evaluated. Nonstructural measures to protect public and private property include elevating or relocating structures, increasing buffers, enhancing vegetation, managing drainage and runoff. Nonstructural measures shall be required when determined feasible, and shall be preferred over structural shoreline stabilization methods.
E. 
Structural shoreline stabilization measures to protect public and private property shall be allowed only when necessity is demonstrated by conclusive evidence, documented by a geotechnical analysis that existing primary structures or infrastructure is in danger from shoreline erosion caused by currents or floods, and damage from such erosion will occur within three years of the geotechnical analysis. The geotechnical analysis should evaluate on-site drainage issues and address drainage problems away from the shoreline edge before considering structural shoreline stabilization.
F. 
When structural shoreline stabilization measures are allowed, the use of soft structural measures, such as bioengineered methods (e.g., jute netting and live staking) or biotechnical methods (e.g., erosion control matting and live cribbing) that provide restoration of ecological functions shall be used, unless a geotechnical report demonstrates that soft structural stabilization measures will not be sufficient and hard structural methods (riprap and gabion walls) are required. Such geotechnical analysis shall address the necessity for shoreline stabilization by estimating the time frames and rates of erosion and report on the urgency associated with the specific situation.
G. 
The size of structural shoreline stabilization measures shall be limited to the minimum necessary and publicly financed or subsidized shoreline erosion control measures shall not restrict appropriate public access to the shoreline except where such access is determined to be infeasible because of incompatible uses, safety, security, or harm to ecological functions.
H. 
Replacement of existing shoreline stabilization structures may be allowed based on demonstrated need. Waterward encroachment of replacement shoreline stabilization structures is allowed only for residences occupied prior to January 1, 1992, and when there are overriding safety or environmental concerns.
I. 
Publicly financed or subsidized shoreline erosion control measures shall not restrict appropriate public access to the shoreline except where such access is determined to be infeasible because of incompatible uses, safety, security or harm to ecological functions. Where feasible, incorporate ecological restoration and public access improvements into the project.
J. 
New stabilization structures for existing structures that are primarily residential are allowed only when no alternatives are feasible, including relocation or reconstruction of an existing structure, and less expensive than the proposed stabilization measure, and then only if no net loss of ecological functions will result.
(Ord. 1252 § 5 (Exh. A), 2021)
A.

(Ord. 1252 § 5 (Exh. A), 2021)
A. 
The maintenance, repair, and replacement of existing utilities is permitted in all shoreline environments.
B. 
Utilities shall be located in existing rights-of-way whenever feasible (including existing transportation rights-of-way), and where new over-water utilities are proposed they shall be located at existing or approved bridge crossings.
C. 
New utilities or the extension of existing utilities is prohibited in the natural environment and the urban conservancy environment unless an applicant can demonstrate there is no feasible alternative, and that all reasonable measures have been incorporated in the design to ensure that the utility is compatible with the purposes of the natural environment or urban conservancy environment as applicable to the maximum extent possible consistent with achieving the purpose for the utility.
D. 
New utility production and processing facilities and transmission facilities are prohibited in all shoreline environments with the exception of the continued operation of the hydropower facility in the hydropower environment consistent with any license issued by the Federal Energy Regulatory Commission.
E. 
Where utilities do exist, utility services routed through shoreline areas shall not be a sole justification for more intense development.
F. 
New utilities and/or utility facilities shall be located outside of shoreline setbacks, buffers, and vegetation management corridors to the greatest extent feasible. The shoreline administrator may allow new utilities and/or utility facilities within the shoreline setback, buffer, and/or vegetation management corridor upon finding that:
1. 
It is not feasible to locate new utilities and/or utility facilities outside the shoreline setback;
2. 
All reasonable measures have been incorporated in the design to ensure that the utility is compatible with the purposes of the shoreline environment designation where the utility will be located to the maximum extent possible consistent with achieving the purpose for the utility; and
3. 
The new utility and/or utility facility is subject to all mitigation conditions that may be imposed to address potential impacts of such facility on shoreline ecological functions.
(Ord. 1252 § 5 (Exh. A), 2021)
A. 
There are hereby established vegetation management corridors on the Snoqualmie River, Kimball Creek, and Borst Lake that are coextensive with the critical area buffers required by Article VI of this chapter through integrated critical areas standards, except in the urban riverfront shoreline environment designation where the vegetation management corridor extends 100 feet from the OHWM of the Snoqualmie River.
B. 
Within vegetation management corridors, the removal of vegetation, other than nonnative invasive species and danger trees, is prohibited except as specifically allowed by these regulations.
C. 
Within vegetation management corridors, vegetation may be removed and/or pruned to provide a permitted trail, boardwalk, or viewing platform for public access and enjoyment including accessory facilities such as individual picnic tables, interpretive or wayfinding signage, benches and water fountains. When permitted, clearing and vegetation removal shall be the minimum necessary to accommodate the permitted development. Trees removed, greater than 16 inches in diameter at breast height, shall be mitigated by a minimum ratio of three trees planted to one tree removed. Replanting shall be accomplished to the extent feasible with species native to the Snoqualmie River basin. Replanted areas shall be maintained as necessary to ensure that vegetation is fully reestablished within three years and shall be monitored for five years.
D. 
Within the vegetation management corridors of Borst Lake and the Snoqualmie River below Snoqualmie Falls, a limited number of put-in and take-out points for nonmotorized boating shall be permitted provided the total number, locations and design shall be reviewed for consistency with public safety and the protection of shoreline ecological functions.
E. 
Vegetation management activities shall be designed to achieve the following vegetation characteristics: diversity of plant species, continuity of habitat and ecological processes, production of snags and downed wood debris, and diverse habitat and edge conditions.
F. 
A vegetation management plan shall be prepared and submitted for approval by the administrator prior to the issuance of any permit or approval for development in the vegetation management corridor.
G. 
Nonnative or noxious species may be removed by manual or mechanical means. Herbicides may be used at the discretion of the administrator when demonstrated that use of manual or mechanical means is insufficient to remove and/or control nonnative or noxious species and when use of herbicides is consistent with King County Noxious Weed Control Program best management practices for control of nonnative or noxious species. Only the use of herbicides approved by the Department of Ecology is allowed.
H. 
Native vegetation removal, other than invasive species, on steep or unstable slopes is prohibited unless part of a project.
I. 
During construction, best management practices for erosion and sedimentation control during construction shall be employed. Vegetation removal that would likely result in significant erosion or the need for shoreline stabilization measures is prohibited.
