Langley Fork Park

Fairfax County, VA

christopher provided design and survey services throughout several stages of the initiative to facilitate site improvements and expansion of the existing recreational facilities at Langley Fork Park in McLean, Virginia. christopher performed boundary surveys and prepared plats for the exchange of land between the National Park Service and the Fairfax County Park Authority (FCPA), to transfer oversight and operation of the Langley Fork Park from the George Washington Memorial Parkway to FCPA.

Subsequently, christopher arborists tagged, identified and assessed more than 400 trees that were surveyed and mapped for a tree inventory over portions of the park that were identified for possible future development. Under a third task order, christopher worked with FCPA to prepare three conceptual layouts to replace one of the existing grass rectangular fields with two artificial surface rectangular fields. The two new rectangular fields were incorporated into the park setting with the two existing diamond fields and existing grass rectangular field that will remain, and parking was expanded and reconfiguration to provide parking and accessible routes to all fields. christopher performed a preliminary outfall analysis and a preliminary stormwater design for quantity and quality control to meet detention and outfall requirements. Stormwater measures included using the artificial field designed to meet guidelines for porous pavement, sizing a stone gallery under the field for detention, and incorporating a filtering structure with underground detention below the proposed parking lot. christopher used the preferred layout to update the Langley Fork Park Master Plan and to prepare a preliminary cost estimate.
