Show Master plan study sites hazards, economic & geologic A Master Plan study for Pleasant Grove City was presented to the Planning Commission at a recent meeting, according to Building Inspector Fred Christensen. The study ws made by 22 students from Brigham Young University's Geography Department. Areas covered in the study include history and preservation, topography, vegetation, climate, geology, surface and ground water, soils, population, transportation, economic base, commercial activities, ac-tivities, housing quality and solid waste disposal. The 87 page document contains pictures and maps and has a complete com-plete bibliography. i One of the items included under , geologic hazards states that there are many possible geologic hazards j of Pleasant Grove, particularly along the mountain front. ' These I include earthquakes, landslides, ! floods and mudflows. It further states that The Wasatch ! . Fault runs along the hills and mountains of east Pleasant Grove. In the past, seismic activity has been high along this fault. The Wasatch Fault is one of the highest seismic risk areas in the western United States. The study says that the present risk from faulting is highest in areas where development has taken place near the Wasatch Fault in Pleasant Grove. This risk can be minimized during future development of the foothills by increased awareness of the fault and methods used to deal with faulting and urban development. develop-ment. , -i Land-use factors which should be considered in the fault area include building occupancy, building height, slope, surface materials, structural systems and quality of construction. The study also notes that as Pleasant Grove's population increases in-creases a nd the urban area expands, there wiil be a tendency to build in this hazardous fault zone. It probably is not feasible to prohibit land-use in the fault zone, but precautions should be taken to minimize the loss of life and property in the evnt of fault movement, the document states. Included in the study is a statement that mudflows from canyons along the Wasatch Front have been a major problem the last few years. Pleasant Grove has debris basins at the mouths of both Battle Creek and Grove Creek Canyons to help prevent such a disaster. Regarding ground water, the study states that Pleasant Grove is built upon alluvial fans from Grove and Battle Creeks, as well as Lake Bonneville sediments. The eastern half of town is well drained due to its elevated nature and the alluviam underneath. The area from about Main Street west and west of Highway 89 on the south is built upon lake sediments and is only about 25-75 feet above the level of Utah Lake. These areas have high water tables and present problems to basements and septic systems. In the summer of 1984 much of the western half of the city had a water table depth of only 3-15 feet. As a result of this problem Pleasant Grove requires more stringent regulations for septic systems than Utah County. Many septic systems in this area are failing. The solution is to connect all involved into the municipal sewer system, the study notes. This is currently underway and will continue con-tinue as funds are available. There is a small area on the east side of the city which isunstable enough to cause structural problems. The area is small and building permits are reviewed on an individual basis. Pleasant Grove has institutions in all three groups of economic activity: ac-tivity: primary, secondary and tertiary. Primary industries are those that take natural resources from the earth, including farming and grazing. Secondary industries are the manufacturing firms, and tertiary industries are those activities which rely on human services. Most residents of Pleasant Grove work in another city. The majority of these work in the Geneva Steel Plant south of Lindon. Other places of occupation outside the Pleasant Grove City Limits are McNally Mountain States Steel in Lindon BYU in Provo and Salt Lake County ' Bayly Manufacturing is the largest employer within Pleasant Grove City with between 200 and 299 employees. Next is Western Utility Contractors with 85; Western Staes construction, 70; Jim Walter Corp 50-99; Ashrock Inc., 50; Skyline ndustries, 20-49; Global Coatings Inc. 20-49; and Southam and Warburton Aluminum, 40. The majority of the employed people of Pleasant Grove work in the tertiary industries, retail, trade, and services. Approximately 41 per cent are employed in some type of these activities. About 61 per cent work in technical and administrative sup port occupations, while 49 r work in service jobs.
