Summary
Anyone building or altering a pier, dock, or boat ramp in Clear Lake's foreshore or nearshore must first get an administrative encroachment permit from Lakebed Management. Placement is capped at a strip beginning ten feet inside extended property lines, measured from the 7.79-foot Rumsey high water mark.
4.1 When Required. No person shall undertake or carry out any of the following activities within the nearshore or foreshore without first obtaining an administrative encroachment permit from the Lakebed Management. (A) Constructing or placing any pier, boat ramp, boat launching facility, navigational structure, buoy, jetty, breakwater, marina, harbor, shorezone protective structure, or any other improvement, a portion of which lies within the foreshore or nearshore... 6.2 Placement of Piers, Docks, Buoys, Boat Ramps, and Launching Facilities. The placement of all piers, docks, buoys, boat ramps or launching facilities shall be permitted only within an area and to a depth defined as follows: (A) An area within lines extended parallel to and ten feet (10′) inward of property lines extending lakeward from the high water mark (7.79 feet Rumsey) into the foreshore and nearshore... (B) To a depth necessary for the safe mooring of a boat.
Full Breakdown
Lake County Code Chapter 23, the Clear Lake Shoreline ordinance, requires an administrative encroachment permit from Lakebed Management before anyone constructs or places a pier, dock, boat ramp, boat launching facility, navigational structure, buoy, jetty, breakwater, marina, harbor, or shorezone protective structure with any portion in the foreshore or nearshore (Sec. 1(A)). The same permit covers filling or dredging, placing cables, pipelines or conduits in the lake, and beach clearing. The Board of Supervisors sets the fees for the encroachment permit, a separate buoy permit, and any special event permit, all payable to Lakebed Management (Sec.
2). A permit does not need renewal unless construction fails to start within one year of issuance (Sec. 3). Placement standards under Sec. 79 feet Rumsey, into the foreshore and nearshore; structures shared by two or more adjacent properties can qualify for a zero lot line setback. Docks must also reach a depth sufficient for safe boat mooring. Concrete boat ramps are barred where they would displace wetland or riparian vegetation on residential parcels (Sec. 1(B)), and where permanent access structures cross wetlands, piers or elevated rail ramps are required instead to limit habitat loss (Sec.
1(A)). On commercial, resort, or public property, a boat ramp needs Planning Commission review and approval of the encroachment permit under Sec. 6(B), and the Commission may condition approval on a contribution to a lake-wide no-net-loss wetland program. An owner of a littoral parcel is generally limited to one pier or dock plus one or two launching facilities other than a boat ramp for use by the owner's family and guests (Sec. 3(A)).
Violations & Fines
Lakebed Management suspends an encroachment permit for violating its terms and revokes it if the holder fails to cure the violation within a 30-day suspension (Sec. 23-20.1(A)-(B)). The permittee gets ten days' written notice specifying the grounds and cure before suspension or revocation, and all construction must stop while a permit is suspended; a revoked permit requires restoring the site to its prior condition. A suspension or revocation can be appealed to the Planning Commission under Sec. 23-4.11. Any violation of Chapter 23 is an infraction punishable by a fine up to $100, or a misdemeanor punishable by a fine up to $500, up to six months in county jail, or both, and each day a violation continues counts as a separate offense (Sec. 23-20.2).
