Changes to the Subdivision Application Process

To allow the City to complete reviews in compliance with the new mandates included in HB 3167, the City has amended Titles 25 and 30 of the Land Development Code (LDC). These changes were passed by City Council on an emergency basis at the August 22, 2019 council meeting and take effect on September 1, 2019.

The Travis County Commissioners Court is scheduled to consider the changes to Title 30 of the LDC applicable to subdivisions in the City of Austin’s Extra-Territorial Jurisdiction (ETJ) with Travis County reviewed by the joint City of Austin / Travis County Single Office at its August 27, 2019 meeting.

Staff will adopt emergency rules that accompany the ordinance prior to September 1st. A high-level summary of the changes is detailed here:

  • Modified review times to be 30 calendar days and 15 calendar days for updated applications;
  • Modified requirements for approval to allow subdivision cases to be heard by either Zoning and Platting or Planning Commission without limitation to adopted neighborhood plan or geographic location;
  • Added provisions to the LDC to clarify that following action other than approval of a subdivision application by the commission, the application may be returned to either commission for subsequent consideration following the submittal of updated information by the applicant;
  • Modified the subdivision application life to be 90 calendar days for Preliminary Plans and Plats and 1 year for associated Subdivision Construction Plans. The application life has been modified to begin when the application is accepted for formal review rather than the current practice of beginning on the date of acceptance for completeness check;
  • Created a Subdivision Project Assessment application and process, to coordinate the evaluation of the code compliance of a proposed subdivision application;
  • Requires the completion of a Project Assessment application for all subdivisions that propose a variance or waiver from adopted code or criteria or a discretionary approval of an alternative compliance measure. A variance request filed with the Project Assessment application will result in an assessment of the variance request, a proposed staff recommendation on the variance or waiver, and a board of commission recommendations where applicable. The variance assessment and staff recommendation will apply to the formal application for subdivisions submitted within the 180-day timeframe;
  • Defined and created a review and approval process for “Minor Plats”;
  • Created a process to provide that a Minor Plat with no associated variances may be administratively approved as provided in 212 and 232 of the LGC;
  • Establish a defined order of approvals in the land development application process - Zoning, Preliminary Plan, Plat, Subdivision Construction Plans, Site Development Permit. This change eliminates most concurrent reviews of subdivision applications and requires final approval of previous prerequisite applications before filing for the next permitting phase;
  • Completeness check will be enhanced to require a complete submittal;
  • Establish prerequisite requirements for the formal acceptance of subdivision applications, including:
    • Completed vested rights determinations, if applicable;
    • Final Council approval of all zoning processes, required or requested, including covenant amendments or terminations;
    • Identification of transportation requirements, including verification of proposed street intersection and driveway access locations by the appropriate jurisdiction;
    • Utility service information including final approved water or wastewater service extension requests, if required;
    • A completed Project Assessment and recommendations for all variances or waivers from code or criteria;
    • Information regarding floodplain delineation or modifications, if the current adopted models are being modified;
    • Parkland dedication verification, if a fee in lieu is being requested;
    • Engineering fiscal estimates; and
    • Identification and final approval of any non-standard real estate documents that may be required based on the design of the proposed development.
