Walnut Creek Watershed

Final Impact Forecasts


Comparison of End Results (After 50 Years)

By comparing the current status of the Walnut Creek watershed with the results of the three proposed scenarios at the end of 50 years, it is evident that although all scenarios will experience some degradation, there are significantly different outcomes. It is obvious that unregulated growth provides no protection against water quality decline throughout the watershed. Mitigation and mitigation plus growth control measures are able to reduce the severity of the water quality decline. Mitigation efforts and mitigation efforts in conjunction with growth controls affect both the rate and the degree of decline. Although using mitigation greatly reduces the effect of urbanization, additional growth controls help to further stabilize development effects.
