Lower Olentangy River Watershed

Final Impact Forecasts

Comparison of End Results (After 50 Years)

By comparing the current status of the Lower Olentangy River watershed with the results of the three proposed scenarios at the end of 50 years, it is evident that all scenarios will experience enough degradation to result in very poor water quality throughout the watershed. In general, it is obvious that unregulated growth provides no protection against water quality decline, while mitigation and mitigation plus growth control measures would be able to reduce the severity of the water quality decline. Mitigation efforts and mitigation efforts in conjunction with growth controls can affect both the rate and the degree of decline. However, although using mitigation and growth controls usually greatly reduce the effect of urbanization, this watershed would require much more stringent regulatory action if it is desirable to stabilize development effects.
