GeoCapitol provided geotechnical and environmental services for Phase 1 of the 67-acre Hill East District Waterfront Redevelopment in Southeast, Washington, DC. Construction plans include two mixed-use buildings including 354 apartments, up to 40,000 SF of retail, and approximately 222 parking spaces.
GeoCapitol completed a Phase I and a limited Phase II Environmental Site Assessment (ESA) for parcels F-1, G-1, and G-2. The environmental reports were utilized to develop the Environmental Impact Screening Form (EISF), which is required by DC development agencies. GeoCapitol also provided geotechnical engineering design services which they completed concurrently with the limited Phase II ESA, significantly reducing the investigation costs for both studies.
The geotechnical and environmental investigation included drilling 14 soil test borings and screening soil samples with a photoionization detector (PID) to detect the presence of volatile organic compounds (VOCs). Based on their engineering analyses of the data collected, GeoCapitol provided recommendations for foundations, lower floor slabs, lateral earth pressures, subdrainage, earthwork, and excavation support. Separate reports were provided to the client detailing the findings of the geotechnical engineering study and Limited Phase II ESA.
