Washington Canal Park is located on a narrow 3-block site in SE, DC. The total project area of improvement is approximately 3 acres.

VIKA Capitol provided surveying and civil engineering services. The design includes innovative systems that will minimize energy consumption and maximize stormwater re-use. This also entails rain gardens to filter and direct water runoff to an underground storage tank that, together with stormwater runoff collected from adjacent buildings, will fulfill the majority of the park’s irrigation demands.

In response to a small portion of contaminated soil under the site, and to minimize contamination of groundwater, the rain gardens will have a waterproof liner and under-drainage system to collect the stormwater and keep it from percolating into the ground water. Because the stormwater generated by the site (and a majority of the surrounding buildings) will not leave the site, the stormwater pollutant load leaving the site will be zero. To meet current and future Anacostia Waterfront Initiative (AWI) stormwater management regulations, the stormwater reuse system will hold and treat at least the first 3.2 inches of rainfall.

Additional sustainable design features include:

  • Street tree pits that function as rain gardens to filter street runoff
  • Geothermal wells for heating and cooling the main pavilion
  • Heat recovery systems linking the waste heat of the skating rink to the pavilion
