1. Marina is within a very active seismic area (Seismic Zone 4). Severe seismic action could disrupt communications, damage gas mains, cause extensive electrical hazards, and place extreme demands on the limited and widely dispersed resources of the fire department, resulting in failure to meet the fire and life safety needs of the community.

2. The local geographic, topographic, and climactic conditions pose an increased hazard in the acceleration, spread, magnitude, and severity of potential fires in the City of Marina and may cause a delayed fire response time, allowing further growth of a fire.

3. The types of roof coverings as set forth in the amendment are a more restrictive standard, which will better prevent fire damage, which can result from local conditions.
