Out of Austin Energy service area. 911 Addressing Review - Cathy Winfrey - 512-974-2398 AD1: This plat review is cleared; however, any changes to street names, street name labels, or street layouts will require a new review. NOTE: This proposed Subdivision is located inside Bastrop County. Please note that any address assignments to resulting lots or changes to existing addresses will be enacted by Bastrop County 911 Addressing. ATD Engineering Review - Amber Mitchell - 512-974-5646 No comment. Drainage Engineering Review - David Marquez - 512-974-3389 Release of this application does not constitute a verification of all data, information, and calculations supplied by the applicant. The engineer of record is solely responsible for the completeness, accuracy, and adequacy of his/her submittal, whether or not the application is reviewed for code compliance by city engineers. DE1. Construction plans, or an approved site plan prior to the plat, will be required for the proposed construction if the proposed construction does not meet LDC 25-5-2. If construction plans are to be proposed, the case number will need to be changed to .1A. DE2. Per the fiscal policy ordinance, the pond and its grading associated for compliance will need to be included in the fiscal estimate. DE3. To demonstrate compliance with DCM 1.2.2 for no adverse impact, submit the drainage model and associated exhibits to demonstrate no adverse impact for the proposed pond will be required per DCM section 2. This will include taking Atlas 14 into consideration. The fist link is to our recent code and criteria changes and the second is specifically for Atlas 14. Included in the calculations should be a demonstration of no increase of point discharge which will mean the flows will need to spread to match existing conditions. 1 http://austintexas.gov/cityclerk/postings/land_dev_rules_notices.htm http://www.austintexas.gov/edims/document.cfm?id=332437 DE4. Per DCM 1.2.oA drainage easement with required maintenance will be required for the water quality and detention pond. Environmental Review - Jonathan Garner - 512-974-1665 EV 1. Erosion and sedimentation control fiscal surety is not required for a Final Plat application without a Preliminary Plan. Remove this amount from the Fiscal Estimates worksheet. 3 of 18B-15PARD / Planning & Design Review - Thomas Rowlinson - 512-974-9372 UPDATE 0 (W/R) PR 1: The parkland dedication and park development fee is required per City Code §25-1-601 and must be paid before the subdivision may be approved (low density fee for a project with less than 6 dwelling units per acre). However, no parkland fee will be collected for the existing residence, so the fee for 4 units is required at this time. Bastrop County Appraisal District only shows one residence. Site plan in application only shows one residence. Any increase in units allowed by subdivision must satisfy parkland dedication at subdivision. The park fee bills have now been issued in AMANDA. The person named as an “Applicant” may pay online at Austin Build + Connect. The fee can be made in one payment though there are two bills. Email the PARD reviewer at thomas.rowlinson@austintexas.gov to request the bill numbers. When payment has been made, email the receipt to this reviewer to clear this comment. PR 2: Update note 11 on the plat: A fee-in-lieu of parkland dedication and park development has been paid for 4 residences. No fee was charged for the existing residence Subdivision Review - Sylvia Limon - 512-974-2767 SR 1. Add the Case # C8-2020-0038.0A, in the bottom right hand corner of each sheet. [LDC 25-1-83] SR 2.

The engineer of record is solely responsible for the completeness, accuracy, and adequacy of his/her submittal, whether or not the application is reviewed for code compliance by city engineers. WQ1. To demonstrate compliance with ECM section 1.6.5.A, submit cross sections and details to demonstrate the proposed pond will be in compliance. WQ2. Per appendix R-2 of ECM, submit an R table that demonstrates the pond is in compliance and sized for ECM standards. If construction plans are to be provided, an R-1 table will be required for the plat. WQ3. Per ECM 1.6.2B2 pertaining to stacked detention, outlet structures are recommended to be on the sedimentation side of the pond to prevent erosion. 5 of 18B-15 WQ4. Demonstrate erosion control per ECM 1.4.0 and ECM 1.6.2B1, a splitter box is typically required. For stacked detention we allow designs to demonstrate that a splitter is not needed if velocity of flows and erosion control are taken into consideration. WQ5. Provide Certification of Compliance 25-1-83 – Applications Related to a Closed Municipal Solid Waste Landfill. The certification form can be found at the following website: http://www.ci.austin.tx.us/watershed/downloads/engineers_cert_form.pdf Site Plan Plumbing - Cory Harmon - 512-974-2882 NO SITE PLAN PLUMBING REVIEW REQUIRED The proposed resubdivision (C8-2020-0038.0A) is outside of the zoning jurisdiction of the City of Austin and will not receive water or wastewater service from Austin Water Utility, therefore the Austin Plumbing Code is not applicable per Chapter 25-1.
