You can just envision the developers salivating over the possibilities of this property.
South Fayette - if they were wise and really cared about property values and were thinking long-term instead how they can personally and politically benefit from this - would just leave the property "wild" and let it serve as a nature preserve and educational vehicle for children. That's it. Recreational uses aka ball fields? An insult. Housing (aka McMansions)? Ugly and another insult. Commercial development (aka chain stores, and traffic)? No way Jose.
Leave it be as is. Let it be quiet and let nature rule - for once.
