A second policy issue is even more controversial. Developers, realtors, and some Lake Don Pedro property owners are pressing Tuolumne County to weaken its septic system rules. Under the current rules, there must be at least two feet of soil on a property before the County will allow specially designed septic systems. If there is only a foot or so of soil over bedrock, no system can be built on that property. CSERC staff has been actively engaged in meetings and study sessions - attempting to keep septic systems off shallow-soil properties, where septic systems are most likely to fail.
Whether it is oak mitigation planning or septic system rules, a strong policy can make a huge difference over time when applied to large numbers of new development projects. If weak new septic system rules allow lots to be created on shallow soils sites near local foothill reservoirs, there will be a high risk for pollution and also a greater loss of open space and scenic values. Likewise, without strict oak protection requirements, it will be easier for developers to wipe out open space and key rural values across the foothills of the local region.
