Reservoirs and storage tanks for subdivisions

A. Subdividers must install storage tanks, appurtenances, and pipelines from the tank site to the subdivision proper in accordance with the department's standards or as otherwise approved by the director. Storage tanks with a capacity of 100,000 gallons or more must be of concrete construction. Storage tanks with a capacity of less than 100,000 gallons may be of steel, concrete, or other material as approved by the director. 1. For residential, hotel, apartment, business, industrial, airport, and commercial districts. Unless otherwise approved by the director, storage capacity required must be determined on the basis of fire flow duration, maximum daily flow, or 1,000 gallons per lot, whichever quantity or basis is greatest. 2. For rural and agricultural districts. Storage capacity required must be determined on the basis of 1,000 gallons per lot for rural districts and 2,000 gallons per lot for agricultural districts. B. Tank site lots, access roads, and pipeline easements must be offered to the County for dedication before the department's recommendation for final subdivision approval. C. Whenever a subdivider is required by the department to install a reservoir or storage tank, together with appurtenances of greater capacity than is required to serve the subdivider's subdivision, the department will make a lump sum reimbursement to the subdivider of the difference in cost, excluding the cost of appurtenances, of the larger reservoir or storage tank and the reservoir or storage tank that would otherwise have been required; except, however, that no reimbursement may be made where the larger reservoir or storage tank serves only areas of land under the same ownership as the subdivision in question. D. Where it is determined by the director that a subdivision does not require new, separate storage facilities, and that existing storage facilities and capacity are available, the subdivider will be assessed storage assessment fees in an amount established in the County's annual budget ordinance. E. Storage assessment fees may be used for any costs related to public reservoir or storage tank construction or maintenance within the County. ( Ord. No. 5761 , § 5, 2025; Ord. No. 3730, § 1, 2010)
