1. All building structures shall conform to the standards set forth in Title 17C PCC, Construction and Infrastructure Standards – Building and Fire Codes.

2. Utility Lines. Utility lines, except for gas pipelines which are prohibited, may be permitted when no other conveyance alternative is available. The applicant must demonstrate that a utility line within a liquefaction or dynamic settlement area has been designed in a safe manner and the potential for rupture or failure has been minimized. Appropriate design feature such as above ground installation, restrained joint ductile pipe, welded steel pipe, pile supports, the use of high density polyethylene pipe fuse welded joints, increased wall thickness, special coating or other measures shall be employed. Automatic shutoff valves shall be provided on fluid or gas transmission lines when failure would create significant environmental or life/safety impacts. The line shall be located above ground and properly anchored and/or designed so that it will continue to function in the event of seismically induced ground deformation. Provision for automatic shut-off of utilities in a ground-rupturing event will be required.

3. Roads, Bridges, and Trails. Roads, bridges, and trails shall be allowed when mitigation measures are provided that ensure the roadway prism and/or bridge structure will not be susceptible to damage from seismic induced ground deformation. Mitigation measures shall be designed for static and seismic loading conditions in accordance with the most recent version of the American Association of State Highway and Transportation Officials (AASHTO) Manual and also for an estimated range of ground surface offset presented in the geotechnical report.

1. Buildings. Buildings shall be prohibited within fault rupture hazard areas and associated buffers.

2. Utility Lines. Utility lines, except for gas pipelines which are prohibited, may be permitted when it can be shown no other conveyance route alternative is available. The applicant must demonstrate that a utility line within fault rupture hazard area has been designed in a safe manner and the potential for rupture or failure has been minimized. Appropriate design features such as above ground installation, special layout, crossing angle, restrained joint ductile pipe, welded steel pipe, pile supports, the use of high density polyethylene pipe with fuse welded joints, increased wall thickness, special coatings or other measures shall be employed. Automatic shutoff valves shall be provided on fluid transmission lines when failure would create significant environmental or life/safety impacts. The line shall be located above ground and properly anchored and/or designed so that it will continue to function in the event of seismically-induced ground deformation. Provision for automatic shut-off of utilities in a ground-rupturing event will be required.

3. Roads and Bridges. Roads and bridges shall be allowed when all of the following conditions have been met:
