KCC 11.06.690(H) requires the work to be mitigated and reviewed through a critical area report.

This includes buildings, decks, and docks. Structures or improvements may be permitted by the adopted shoreline master program (SMP) or under the following circumstances, when properly mitigated: 1.

Full Breakdown
690(H), part of Kent's critical areas ordinance, states that unless an exception applies, no structures or improvements are permitted within the lake, river, stream, or naturally occurring pond buffer area, and specifically names buildings, decks, and docks as covered structures. 690(H)(6). Any of the listed exceptions must still be properly mitigated. 101. 58 RCW, a Kent dock project routes through both the shoreline permit process and the critical-area buffer review before construction can begin; the critical area review process is explicitly not meant to duplicate, but to run alongside, other required permits such as the shoreline substantial development permit.
Violations & Fines
Building a dock or other structure within a regulated lake, river, stream, or pond buffer without an approved exception or shoreline permit violates KCC 11.06.690(H) and is enforced through the city's critical areas and code enforcement provisions, which can require removal of the unpermitted structure and mitigation of any buffer damage before further permits are issued.
