In all areas of special flood hazards, the following standards are required:

A. Anchoring.

1. All new construction permitted under LMC 14.34.082 and substantial improvements, including those related to manufactured homes, shall be anchored to prevent flotation, collapse or lateral movement of the structure resulting from hydrodynamic and hydrostatic loads including the effects of buoyancy.

2. All manufactured homes shall be anchored to prevent flotation, collapse, or lateral movement, and shall be installed using methods and practices that minimize flood damage. Anchoring methods may include, but are not limited to, use of over-the-top or frame ties to ground anchors.

B. Construction Materials and Methods.

1. All new construction and substantial improvements shall be constructed with materials and utility equipment resistant to flood damage;

2. All new construction and substantial improvements shall be constructed using methods and practices that minimize flood damage;

3. Electrical, heating, ventilation, plumbing, and air conditioning equipment and other service facilities shall be designed and/or otherwise elevated or located so as to prevent water from entering or accumulating within the components during conditions of flooding.

C. Utilities.

1. All new and replacement water supply systems shall be designed to minimize or eliminate infiltration of floodwaters into the system;

2. Water wells shall be located on high ground that is not in the floodway;

3. New and replacement sanitary sewage systems shall be designed to minimize or eliminate infiltration of floodwaters into the systems and discharge from the systems into floodwaters; and

4. On-site waste disposal systems shall be located to avoid impairment to them or contamination from them during flooding.

D. Subdivision Proposals.

1. Subdivision of areas of special flood hazard for the purpose of developing residential structures is prohibited. Where special flood hazard areas are part of an ownership with an area outside of the special flood hazard area that can be subdivided, flood hazard areas shall be designated and deeded as open space. Open space areas within a flood hazard area shall be deeded to either the subdivision lot owners association, the city of Lacey, or other public entity for protection and preservation, at the sole discretion and determination of the city of Lacey.

2. All subdivision proposals shall be consistent with the need to minimize flood damage.

3. All subdivision proposals shall have public utilities and facilities, such as sewer, gas, electrical and water systems, located and constructed outside of the area of special flood hazard.

4. All subdivision proposals shall have adequate drainage provided to reduce exposure to flood damage.

5. Where base flood elevation data has not been provided or is not available from another authorized source, it shall be generated for subdivision proposals and other proposed developments which contain at least fifty lots or five acres (whichever is less).

E. Storage of Materials and Equipment.

1. The storage or processing of materials that could be injurious to human, animal, or plant life if released due to damage from flooding is prohibited in special flood hazard areas.

2. Storage of other material or equipment may be allowed if not subject to damage by floods and if firmly anchored to prevent flotation, or if readily removable from the area within the time available after flood warning.
