Water Quality/Drainage Reviewers in the Land Use Division perform pre-construction review for water quality and drainage for site plans and subdivision plans to assure compliance with the Land Development Code.
They check these things:
- The pattern and quantity of stormwater discharge to assure no adverse impacts.
- The control of water quality to assure compliance with the Land Development Code.
- Assurance that stormwater discharge does not cause downstream erosion.
- Determination of drainage easement requirements.
- Modification of floodplain (FEMA and City of Austin fully developed 100-yr floodplain).
Subdivision Plans are also reviewed for compliance with the Land Development Code on:
- Geometry (horizontal and vertical) of roadway design (local and collector streets)
- Pavement Design
- Inlet design
Site development permits for subdivisions and site plans are issued by the Engineering/Drainage Section of Watershed Protection Department (WPD) at the time of plan approval and related fiscal surety has been secured. Any construction, whether site or building, requires a permit to be issued before construction begins. Further, for new subdivisions, public infrastructure such as streets and utilities must have been accepted before building permits are issued.
