18686 geologic hazards and the severity of soil problems which are constraints to development. Such geologic hazards exist when certain combinations of slope, soil conditions, and m0isture conditions render land unstable. 13. The statewide agricultural goal definition is based upon the U.S. Soil Conservation Service's Soil Capability Classification System. The majority of land in the metropolitan area is loca- ted on agricultural soils rated Classes I through IV and much of this area has already experienced urban development. The hillside soils are generally included in nonagricultural rated Classes V through VIII. 14. Commercial forest lands within the metropolitan area are general l o -cated in rural areas south of Eugene and Springfield with the largest concentration located southeast of Springfield, 16. The Willamette and McKenz-ie Rivers run through many jurisdictions, necessitating cooperative water management planning -.and considera- tion for downstream effects of actions taken by a single juris- diction, 16. Unless - special precautions are taken, development within the flood- way fringe (that portion. of the flood plain having a One percent per year chance of occurrence - al so known as a 100 year fl ood) i s subject to hazards to life and property from flooding,-, 17. Many portions of the floodway .fringe contain natural assets such as significant vegetation, wildlife and scenic areas and productive agricultural lands and are thus valuable for open space and recrea- tion. ' On the other hand, because of their central location, some f l oodway fringe areas, within the urban service area are important lands for urban development. 18 While development and in-filling have decreased the amount of open space (and associated vegetation and wildlife hab t at) within the urban service' area, the compact urban growth form has protected open space on the urban fringe and in rural areas-within the metropolitan area. 19. Compact urban growth results in pressure on open . space .within the current urban service area . Programs for presery i ng ' qual i ty open space wi th i n . the projected. urban service area become more impor- tant as the area grows. 20. Inventories of vegetation, wildlife, and wild 1 ife habitats resulted in the identification of significant areas, Water, wetlands and areas of diverse vegetation are the most productive wildlife habitats within 'the metropoI itan' area. over half the signif- icant vegetation and wildlife areas identified i n the inventories are already in public ownership.
