This industrial growth will bring an estimated influx of at least 20,000 people to the Weber County area. Weber County Planning Commission has in the approved area to house the anticipated growth. Refer to the map . . . The subdivisions are as follows. South of the Westgate Mobil Park, along highway 89, a 100 lot subdivision called Country Place, will be built with a 60 space expansion on the mobil park. x four-ple- x lots are planned directly across from the mobil park, which will be known as Valley West Thirty-si- Estates. Road Pioneer Along another larger n is planned under the name of Win wood. Another subdivision is on the drawing board, but is not as yet approved, will fall slightly within and adjacent to the incorporated city limits of Plain City. It will be called Randall Acres. It is planned that all sub divisions will be served for sewer hook-up- s by a trunk line into Weber Central Sewer District (shown on the map as a dotted line.) wsc class A class in sports officiating for baseball and softball will be conducted at Weber State College from Feb. 5 through 21.

Part one was published in last week's CATALYST and it focused on general information about the Wasatch Fault. Part three will investigate quake preparation and emergency proceedures. The intent of this series is to inform and not scare the public. It's no secret that Weber County, and the entire Wasatch Front is located in an extremely hatardous potential zone for earthquakes. The Wasatch -- Fault Zone is potentially considered to be one of the Most laymen may be inclined to conclude that the Wasatch Fault must be dead, but what worries most geologists is that the fault is now apparently locked together. Locked faults store up energy for a big quake since they have no way to release quakes. The stress in small Utah Association Geological has predicted that a major earthquake of at least a 7.5 Richter scale intensity will hit the Wasatch Front within the next century. On the Richter scale, a 7.0 quake or higher will cause widespread destruction. Every increase of one whole number on the scale repreaents a ground ten times movement March 1975 The greater.

Fred a Weber State Pashley, Geologist and perhaps Ogden's foremost quake believes that expert anything built on the fault line would be wiped out in a major quake. He feels that a 7.5 quake along the fault non-serio- would destroy all buildings 1,500 feet west of the fault and 200 feet to the east. Some h.riWHwg in those areas may not coUapoe, but none would be salvageable. Generally the fault is at the foot of the mountains and Weber State College has some buildlngi right on top of the fault like: Maintenance building. Wildcat Stadium and the Dee Eventa Center is within 500 feet of the faultline. Some buildings 10 kilometers from the fault line built on sandy foundations might suffer more damage than thooe built on bedrock near the fault. BUILDINGS: Moat deaths In quakes are cauaed by txdkBngs collapsing. Prior to 1951 buildings in Utah were built only to withstand gravity and wind.

Most of Ogden's natural gas comes from Rock Springs., Wyoming through Weber Canyon, while only 5 per cent of the counties' electric cables are underground.

It took two weeks alone in 1975 to dear Ogden Canyon after a landslide.
