Provide drainage easement for the conveyance of off-site flows through the property. The drainage easements shall encompass the limits of the 100 year fully developed flow per LDC 25-7-152 and shall meet the minimum widths specified in DCM 1.2.4.G. Verify the floodplain information shown on the Cover Sheet. The flood map appears to be incorrect. Remove General Note 23. The erosion hazard zone analysis shall be completed with the preliminary plan. ATD 1. DE 1. DE 2. DE 3. DE 4. Provide an erosion hazard zone (EHZ) analysis per DCM Appendix E. DE 5. DE 6. DE 7. DE 8. DE 9. DE 10. DE 11. DE 15. DE 16. DE 17. DE 18. Show the limits of the delineated erosion hazard zone as determined by the EHZ analysis per DCM Appendix E. Verify existing drainage area boundaries. It appears that drainage area 1a and 1h have been merged. Verify Note 4 of the Existing Drainage Conditions notes. A curve number of 90 does not reflect good condition at greater than 75% of grass cover per DCM Table 2-5. Provide documentation showing that the existing development was approved to participate in the Regional Stormwater Management Program. It is not included in the Engineering Report as the plans state. Provide verification that a previous RSMP agreement covers the proposed development per DCM 8.2.2. Visit the City of Austin's RSMP website at https://www.austintexas.gov/department/regional-stormwater-management-program for the Feasibility meeting Request Form and follow the instructions provided to setup a RSMP Feasibility meeting if one has not already been had. Note that detention may be required. Show all proposed drainage easements on preliminary plan. All drainage easements are to be located adjacent to property lines (not centered on property lines). [LDC 25-7-151] Provide additional information and clarification on the proposed storm drain lines. The proposed storm drainage appears incomplete as it just ends without connecting into an outfall. [LDC 25-7-61] DE 12. Remove the word public from the proposed storm drain labels. DE 13. Specify the type of easement the proposed storm drain is located within. DE 14. Show how stormwater control measures will convey flow off-site. [LDC 25-7-61] Ensure all existing storm drain infrastructure is shown on the storm drain plans per the subdivision application instructions. There appear to be pipes and structures missing. Include the size and material of the infrastructure. Verify that the grading plans are complete. The plans show proposed grades that do not tie into existing contours. [LDC 25-7-61] Specify the limits of proposed roadway improvements to existing roadways. The grading plans appear to show new proposed grades for existing roadways. [LDC 25-7-61] Revise engineering report. There is a statement in the Drainage and Stormwater Management section that is inaccurate. The requirement for on-site detention is not based on the amount of impervious cover. See code and criteria sections LDC 25-7-61, DCM 1.2.2. Environmental Review - Mike McDougal - 512-974-6380 Tuesday, August 30, 2022 EV 01 After additional research, an administrative variance is not required to cross the Critical Water Quality Zone with Elmont Drive per LDC 25-8-262(D). Remove the reference to the variance from the coversheet. Flood Plain Review - Kena Pierce - 512-978-1832 Applicant must remedy all compliance issues without creating additional compliance issues with the LDC and/or Criteria manuals. A response that fails to correct an issue, or which creates other issues does not comply with the LDC and is insufficient to address the comments. The comments provided describe an issue that must be remedied in order for the application to be approved. Any specific examples are provided as a courtesy and are not intended as an exhaustive list, especially as the site may be updated to have additional compliance issues. Contact this reviewer if you have any questions, kena.pierce@austintexas.gov. FP 1.

Previously reviewed and approved by Kristi (though several comments indicated that confirmation of compliance would be needed at future stages). Update 4 officially allowed because it’s been a hot minute since the last review (i.e. 1 year) and the engineer has changed and the plan has changed somewhat. Modeling comments below are from a complimentary review of the model completed by Katina on 2/14/2022. Based on a follow-up meeting with the engineer on May 2, 2022, the actual review and approval of any floodplain modifications proposed with this development are actually approved at time of subdivision construction or site plan stage, so at this point we really need to see “proof of concept” since we don’t have things like finalized grading plans. Project Area on main stem: XS 10477 to halfway between 8080/7560; both sides of the creek are the project area between XS10477 and XS9169, left side only for the remaining project area. Project Area on Trib1 is from XS543 to outfall on the left side of the creek. UPDATE 4: Corrected Effective RAS and HMS modeling provided on May 25, 2022 and located on LUR file system, Proposed RAS modeling and updated report provided on June 20, 2022 directly to reviewer and saved on WPD file system. Applicant needs to provide proposed version of the models to DSD Intake at next update. RAS modeling has been accepted as meeting No Adverse Impact requirements. NOTE TO FP REVIEWER: Modeling will need to be confirmed to still match proposed grading, NAI regulations, and that easement contains the post project floodplain on future site development submittals. See other “deferred” comments below which will also need to be addressed at the appropriate site development stage.” During subdivision construction/ site development stage, refer to this PA deferred comments to ensure work is in compliance with code.
