Garberville Sanitary District Water System Improvements Project General Plan Conformance Review and Special Permit Record Number: PLN-2023-18803 Assessor Parcel Numbers: 032-121-009, 032-135-002, 032-211-011, 032-211-021, 032-211-035, 223-181-020, 223-181-024, 223-181-025, 223-183-003, 223-191-006 and 223-191-011 Garberville area A General Plan Conformance Review and a Special Permit for the Garberville Sanitary District (GSD) to replace the existing 180,000-gallon, in-ground, concrete, finished water storage tank (Hurlbutt/Main Tank) and a 20,000-gallon, failing, redwood drinking water storage tank (Wallan Tank) with two new increased capacity tanks. In addition, the failing Robertson Tank, which has been taken out of service, would be demolished. The new Main Tank would be an in-ground, approximately 550,000-gallon, pre-stressed concrete tank located on an adjacent parcel and similar elevation to the existing tank. The existing Wallan Tank would be replaced with an approximately 77,000-gallon bolted steel tank. Both of the existing tanks in operation are leaking and lack sufficient storage capacity for maximum daily consumption and fire suppression; they also do not meet current seismic design standards. In addition, the GSD proposes to replace or upgrade three booster pump stations (Upper Maple Lane Pump Station, Arthur/Alderpoint Pump Station, and Wallan Pump Station). The existing Upper Maple Lane Pump Station is located in the existing Hurlbutt Tank and would be demolished when the Hurlbutt Tank is demolished. A new Upper Maple Lane Pump Station would need to be constructed at the site of the new Main Tank. The existing Arthur Pump Station is in poor condition and has operational deficiencies that would be improved when this pump station is replaced by the Alderpoint Pump Station. The Wallan Pump Station is in poor condition and requires upgrades to meet the operational requirements of the new Wallan Tank. New backup generators would be installed at each replaced or upgraded booster pump station and at the Tobin Well. The proposed project includes conveyance of the existing Hurlbutt/Main Tank parcel (APN: 032-211-011) to the existing landowner and creation of a separate legal parcel for the proposed 550,000-gallon tank on APN: 032-211-021 for development of the access road and ground disturbances to install water lines to the new 550,000-gallon Main tank. The Special Permit is required for work proposed within the streamside management area (SMA) of an unnamed ephemeral stream on APN: 032-211-021. As Lead Agency, the Garberville Sanitary District adopted a Mitigated Negative Declaration (State Clearinghouse #2023100664) pursuant to Section 15074 of the CEQA Guidelines.
