Please note that the projects listed below pertain primarily to stormwater analysis and modeling. Our Land Development page lists several additional projects for which stormwater management and conveyance were integral.
 Regional Stormwater Detention/Water Quality Improvement Ponds |
| Regional Pond S-7; Fairfax County, VA Lead Engineer for hydrologic analysis and design of regional stormwater management pond for 650-acre drainage shed. This facility was designed immediately upstream of an existing roadway containing two 60 inch raw water transmission mains. Two existing 72 inch culverts were present within the roadway embankment and two more were added. An emergency spillway was not possible for this facility, therefore the four 72 inch culverts were supplemented by a complex outlet structure that provided stormwater quantity and quality improvements while being able to pass the probable maximum flood. Two public meetings were held with adjacent residents to educate them about the project's importance and recreational trails were designed adjacent to the facility.

| Underground Stormwater Detention/Water Quality Improvement |
| Asthma and Allergy Center; Roanoke, VA Lead Engineer for 1-acre site development including planning, grading, parking layout, stormwater conveyance, sanitary sewer, water, and underground stormwater detention. The underground stormwater detention facility was unique in Roanoke because it did not have a gravity outfall. The stormwater is pumped from the facility at a rate equal to the predeveloped flow rate. Ongoing monitoring of this facility shows it to be functioning flawlessly.  Safeway Supermarket; Fairfax, VA Lead Engineer for designing underground stormwater management and water quality improvement structure (D.C. sand filter) to allow expansion of an existing Safeway supermarket.

| Watershed and Flood Plain Analysis |
| Churchville Avenue Storm Drain Improvements; Staunton, VA Lead Engineer for hydrologic study of 640-acre urban area comprised of 30+ subsheds, all of which were modeled using TR-55 and TR-20 methods. The data was used to design several thousand feet of large scale storm drain piping and box culverts along a busy urban collector roadway. Cattail Branch Floodplain Analysis; Leesburg, VA Lead Engineer responsible for HEC-2 analysis of existing major urban floodplain. Analyzed existing condition and three alternatives for crossing including box culverts, bridge, and concrete arch type culverts. Performed cost analysis and recommended arch type culverts as most economical given the required maximum water surface elevation. |
