Water Quality Review and Drainage Engineering Review in the Land Use Review Division perform pre-construction review for water quality and drainage regulations for development applications to ensure compliance with the Land Development Code and Criteria Manuals.

The following items are reviewed:

  • The pattern and quantity of stormwater discharge to ensure no adverse flooding impacts. (Land Development Code 25-7-61)
  • The treatment of stormwater for water quality purposes to ensure compliance with Land Development Code 25-8-211.
  • Assurance that stormwater discharge does not cause downstream erosion (Land Development Code 25-7-32).
  • Determination of drainage easement requirements (Land Development Code 25-7-152).
  • Floodplain requirements (Land Development Code 25-7-33 and 25-7-92) (FEMA and City of Austin fully developed 100-yr floodplain).

Any construction, whether site or building, requires a permit before construction begins. Further, for new subdivisions, public infrastructure such as streets and utilities must be accepted before building permits are issued.
