G. Fences and Decorative Freestanding Walls in the Historic District. Fences constructed in the Historic District shall comply with the Design Standards and Guidelines for the City’s Historic District.
H. Retaining Walls and Rockeries.
1. Retaining wall and rockery installations in all land use designation areas shall comply with the adopted City of Snohomish Design Standards and development regulations which are applicable to the area where the retaining wall is located, except that:
a. There shall not be a maximum height limit on retaining walls and rockeries located in the buildable area of a lot. However, the height of retaining walls and rockeries in the buildable area of a lot shall be the lowest necessary to achieve its intended functional purpose. If the proposed wall or rockery height exceeds the height limitation for the land use designation area where it is located it must be reviewed and approved by the Planning Director or designee on a project-by-project basis.
