Maintenance Building

To minimize the visual impact of the 5,000 square foot Maintenance Building, part of the structure was built into the ground, giving it a low profile. (July 2014 photo)

Park Center

As part of stormwater management, the parking areas are water permeable, allowing rainwater to pass through the asphalt to an underlying stone bed. Water is then absorbed by underlying soil. (July 2014 photo)

Caretaker's House

The House was strategically built on the hill to the southwest of the parking area to provide the caretaker with exceptional views over the entire park to enhance security. (December 2013 photo)

Multi-Use Trail System

As part of the new reservoir project, many of the park’s trails have been improved, realigned, or reconnected in order to limit environmental impacts, reduce user conflicts, improve accessibility, and reduce fall-line impacts and steep grades.
