Willard Intermediate School

Loudoun County, Virginia

At a glance: Terraset Elementary School (TES) is located on a 14.4352-acre parcel in Reston. The school was originally constructed in 1977 as a completely underground facility. The first step of the process for the expansion of this school was to gain approval of the Planned Residential Community Application (PRC) from the Fairfax County Board of Supervisors. This application required extensive coordination with the Reston Association Design Review Board and the Reston Planning and Zoning Committee. A total of 33,463 square feet of floor area were added to the existing 68,880-square-foot building.

The design for this facility included: site grading, storm and sanitary sewer layout and design, waterline layout and design, a two-phased erosion and sediment control plan, landscaping plan in accordance with Fairfax County requirements. The requirements of the PRC Plan as well as other zoning requirements also had to be met. SWM/BMP utilizing Low Impact Designs included conservation areas, pervious pavers for the entire parking lot, pervious pavement for the basketball courts and four filterra units. Stormwater management was also met using two 72-inch detention pipes. In addition, RDA prepared a Resource Protection Area (RPA) Delineation for the area adjacent to Snakeden Branch to confirm the location of the RPA for Fairfax County. One of the major challenges of this project involved tying the proposed facilities in with the existing site. Improvements were made to the existing infrastructure where necessary. We were able to meet the school’s site needs while addressing environmental and zoning requirements in addition to the concerns of the Reston Association. The greatest challenge of this project involved the merging of the proposed facilities with the existing underground facility on a very narrow site. As part of this project’s construction administration tasks, we answered RFIs, reviewed PCOs, and issued supplemental information, when necessary. This project was completed on-time and under budget.
