City of Sunset Valley Assumes Subdivision Regulation in ETJ

May 7, 2013 by Matthew Stewart

StewartKnown primarily as a premier shopping destination, the City of Sunset Valley is located southwest of downtown Austin and had a population of just under 800 people during the 2010 census. It is surrounded on all sides by the City of Austin.

When real property is located in the Extra Territorial Jurisdiction (ETJ) of a municipality, Chapter 242 of the Local Government Code (and State of Texas House Bill 1445 of the 77th Legislative Session) mandates that the municipality and affected county enter into a written agreement which identifies the jurisdictional review and approval process for subdivision applications (Local Government Code 242.001). The authority could rest solely with the city or the county, be divided geographically among the city and county with each keeping authority in only one portion, or a single combined office could be implemented to create a joint subdivision review process.

Well, recently Travis County and Sunset Valley have agreed to an interlocal agreement giving the sole authority for subdivision review in the ETJ of Sunset Valley to the City. This means that the County will not review any new subdivision plat applications, including resubdivision and amending plats, in the city limits or ETJ of Sunset Valley. The arrangement was approved by the City on April 4, and the Travis County Commissioners Court unanimously voted in favor last week.


Travis County will still issue development permits in the ETJ through the county office, and the county will still review septic permits and floodplain modification applications.
