前石窟公园的石砾采矿场  – 令人沮丧的住宅和商业价值。 自然恢复在贫瘠的景观上，但并没有解决平衡新发展的野生动物栖息地与社区娱乐需求的解决方案。 设计研讨会将人与人之间的风景和由自然形成的景观之间的并置成公园设计，其强烈的形式反映了该网站过去的使用，并描绘了人类活动和自然功能的未来机会。 40英亩的湖泊和湿地是计划的中心，提供大量的开放水域，并且还可以作为一个滞留盆地和自然过滤器，用于超过9700英亩的周边土地。

The former gravel mining site of Cornerstone Park was a dangerous eyesore – depressing residential and commercial values. Nature was reestablishing itself on the barren landscape, but no solution existed for balancing newly developing wildlife habitat with community recreation needs. Design Workshop translated this juxtaposition between landscapes shaped by man and those shaped by nature into a park design whose strong forms reflect the site’s past use and delineate future opportunities for human activity and natural function. The 40-acre lake and wetlands are the center of the plan – providing a large body of open water and also serving as a detention basin and natural filter for over 9,700 acres of surrounding land.
