VIKA Capitol prepared a stream survey within Alger Park in SE, DC. The survey was needed for the design and retrofit of Low Impact Development (LID) stormwater management facilities.
Components of the new survey include:
- Longitudinal profile of the new reach (~1,600 ft)¾(Along the stream thalweg, measurements will be taken at every grade change or every 50 ft., whichever is lesser)
- 15 cross sections
- Horizontal and vertical location of approximately 6 stormwater outfalls.
- Horizontal and vertical locations of utilities marked from the DC One Call within the park boundary
- Horizontal and vertical locations of underground municipal utilities: storm sewer, sanitary sewer, water lines (horizontal location only), and any other municipal utilities located within surrounding streets
