DEPARTMENT COMMENTS: The request is for the approval of the Easton Park 4B East Preliminary Plan. The plan is comprised of 3 lots on 21.067 acres, proposing 1 mixed residential lot, and 2 other lots for greenbelt/open space/drainage easement, and approximately 1,905 linear feet of right-of-way/streets. The property connects to William Cannon Road to the north and will realign a portion of Finial Drive (formerly named Colton Bluff Springs Road). The applicant also proposes to abandon a portion of Finial Drive for the realignment. The owners have submitted an application for this process with Travis County, and has received pre-approval from utility providers and other parties to the street abandonment area. Staff will be coordinating the abandonment application with the final plat application (out of this preliminary plan) to Court for final approval. Sidewalks are proposed on all streets. The proposed lots comply with the PUD zoning requirements for use and lot size. Parkland will be in compliance with the PUD. Water and wastewater will be provided by the City of Austin. Staff recommends approval of the preliminary plan, subject to the conditions listed in the attached comment report. After the conditions are met, the plan will comply with LDC 30-2-84. The conditions include remove or update notes, define easements, update engineer’s report and drainage information, etc. These are administrative actions that require no discretionary review. An application that has been approved with conditions may be updated to address those conditions until the application expires and the plan does not need to be heard before the Commission again. STAFF RECOMMENDATION: Staff recommends approval of the preliminary plan, subject to the conditions listed in the comment report dated February 24, 2022 and attached as Exhibit C.

[LDC 25-8, Article 1] Flood Plain Review - Katina Bohrer - 512-974-3558 Reviewer notes: Culvert modeling initially reviewed and approved with PA for C8J-2020-0148% and C8J-2021-0043PA. At the PA stage, the proposed culverts (proposed to be built under different plans than this) resulted in adverse flood impacts which must be proven to be mitigated by the time the culvert is permitted to be built (i.e. subdivision construction). The applicant’s engineer indicated that they would pursue easement acquisition to prove compliance with No Adverse Impact requirements at Sub Const. NOTE TO REVIEWER: Floodplain report, including pre, post, and FEMA FP maps is contained as an appendix to the Engineer’s report (in AMANDA as 12/15/21 Eng Report). In Date: 10/7/2021 Notice to applicant: 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 at Katina.Bohrer@austintexas.gov FP1. The site, as shown on the plan provided, is not in compliance with the following sections of the Land Development Code. Please correct your application to be in compliance with Code. 30-4-5 – Determination of the 100-year floodplain 30-4-7 – Computation of Stormwater Runoff 30-4-31 – Single Office Authorized to Require Drainage Studies 30-4-33 – Floodplain Maps, Delineation, and Depiction 30-4-61 – Criteria for Approval of Development Applications 30-4-62 – Certificate of Professional Engineer Required for Certain Alterations and Improvements 30-4-64 – Design and Construction of Drainage Facilities and Improvements 30-4-152 – Dedication of Easements and Rights-of-Way Detailed information: a. The associated HMS/RAS for floodplain was not included in the submittal. Please submit the associated modeling for a complete case file and concurrence it still matches the current submitted plan. b. Why is the entire subdivision construction plan for Prospect Park (adjacent lot) provided for this submittal? Was it to prove that the Prospect Park project is taking into account the Cota Vista crossing and the rises will be contained to drainage easement on that property? c. The previously reviewed and approved modeling for this project showed a rise in Water Surface Elevation upstream of the proposed Cota Vista Drive crossing. It appears that the lot just upstream of Cota Vista is a proposed DE/Open Space lot which is fine for this site; but it will need to be proven that the lots upstream of this site have adequate drainage easement to contain the post project floodplain. The easement will be necessary to get subdivision construction approval. (FYI: Prospect Park is to the south [C8J-2021-0148%] and an unknown Easton Park subdivision to the north [maybe it’s Easton Park 3A [C8J- 2018-0105%]? Per GIS, it appears that the lot to the north of the tributary is unplatted, but I suspect it’s actually within one of the Easton Park submittals]) (highlighted lot below is the one I’m concerned about, it is directly to the west of the Easton Park 4B East Prelim, and on the north side of the tributary – it will need to be proven that the post project floodplain is contained to drainage easement in this area at Subdivision Construction)  FP2. The site, as shown on the plan provided, does not meet requirements set in the Drainage Criteria Manual Section 1 “Drainage Policy.” Please correct your application to be in compliance with Criteria. Detailed information: a. The associated HMS/RAS for floodplain was not included in the submittal. Please submit the associated modeling for a complete case file and concurrence it still matches the current submitted plan. FP3. The modeling provided does not meet requirements set in the Drainage Criteria Manual Section 2 “Determination of Storm Run Off.” Modeling must be in compliance with criteria prior to approval. Detailed Information: a. The associated HMS/RAS for floodplain was not included in the submittal. Please submit the associated modeling for a complete case file. FP4. The modeling provided does not meet requirements set in the Drainage Criteria Manual Section 6 “Open Channels.” Modeling must be in compliance with criteria prior to approval. Detailed Information: a. The associated HMS/RAS for floodplain was not included in the submittal. Please submit the associated modeling for a complete case file and concurrence it still matches the current submitted plan.
