Flood Plain Review - Katina Bohrer - 512-974-3558 Site is located in North Fork Dry watershed and is located in the headwaters of two tributaries which do not have detailed study areas. Tribs are partially FEMA zone A (unstudied) and completely unstudied but within the CWQZ which indicates likelihood of more than 64 acres of drainage. Prelim plan shows 25 and 100-yr floodplains, easement, FEMA floodplains and an engineering report is provided which indicates that Atlas 14 was used to determine the extent of the floodplain. Associated modeling was provided and has been uploaded to our network. Workmaps are included in an attachment to the report. Floodplain Review of associated Project Assessment was completed on 5/6/2021. Applicant indicated that proposed crossings are to be built in the future, but not with the Prelim/Plat (obviously). FP review for Prelim/Plat was deemed to be complete, but the bolded information below needs to be checked at SubConst Stage: Modeling for proposed crossings shows localized rises in WSEL. Applicant has confirmed that all off site rises will be contained to drainage easement to be obtained as part of subdivision construction plan (or dedicated prior to Sub Const as part of the platting process for the adjacent properties). This process is acceptable as the roadway crossings may change up until the Sub Const stage which may affect the floodplain. FYI: Floodplain is shown to be contained to a delineated drainage easement in compliance with code and criteria. It does not, however, appear there is any information provided for bearings/metes & bounds for the easement itself. It is my understanding that a delineated easement to be dedicated by plat still needs to have enough information to be able to locate the easement on the property (measurements, bearings from known points, etc.). For questions related to easement delineation requirements on plats, please talk to the case manager. As this is a prelim plan, I believe that the easement delineation as shown is sufficient, but realize it may not be sufficient for platting. Transportation Planning - Martin Laws - 512-974-6351 TR1. TR2. On preliminary plans, provide a table specifying street classifications, right-of-way width, pavement width, cross-section (shoulders, curb and gutter, or ribbon curb) and sidewalk location (if applicable) in accordance with the TCM, Sec. 1.3.0. On preliminary plans, provide a plat note stating that streets will be constructed to City of Austin standards and dedicated as public right-of-way with the final plat. LDC 25-6-171(a). AW Utility Development Services - Bradley Barron - 512-972-0078 AW1. Per Utility Criteria Manual Section 2, §15-9, §30-2, §25-5, §25-9, and the Uniform Plumbing Code: The landowner intends to serve each lot with City of Austin water and wastewater utilities in accordance with approved Service Extension Requests 4905 (W) and 4906 (WW). Each lot must have a separate water and wastewater utility connection and no existing or proposed plumbing may cross lot lines. The landowner, at own expense, will be responsible for providing the water 3 of 13B-10and wastewater utility improvements, offsite main extensions, system upgrades, utility relocations and or abandonments to serve each lot. FYI. The landowner must pay the tap and impact fee once the landowner makes an application for a City of Austin water and wastewater utility tap permit. Water Quality Review - David Marquez - 512-974-3389 WQ1 Preliminary note 12 should be removed as per LDC 30-5-211. WQ2 Demonstrate or discuss how all impervious cover will be treated as per LDC 30-5-211. Areas in question are areas that drain away from the streets such as block M lot 35-44 or block a lots 1-10. WQ3 For the storm drain system that starts at Apogee, verify that there is enough cover and fall in the storm drain system to the point of the pond so that the system meet DCM section 5 standards. On Pallas for instance, inlets collect at approximately 590 to begin the storm drain. Water is in the pipe for over 3,000’ and discharges into pond b that appears to discharge into a pond that is in the 540’s elevation. This seems possible but the slopes are fairly low in that stretch and variances for minimum velocities would want to be avoided. Possible redesign to add ponds if flows cannot get to the pond may be needed if flows cannot reach the pond so it should be looked into now prior to locking in lot locations. WQ4 An erosion hazard zone analysis should be completed for the greenbelt trail if trails are to be added. Per DCM appendix E and LDC 30-5-261.

Zoning Land Development Review - Amy Combs - (512) 974-2786 ZR1. Please clarify what is meant by “single family lots” on the plan and application. Is it meant that the proposed lots would either be “Residential Detached (Yard House and Others)”, or “Zero Lot Line Detached (Yard House)” as described in Ordinance No. 20151217-080, Exhibit G? ZR2. Please replace all of the dark grey hatching representing the access easements on all of the flag lots on the face of the plan with a lighter hatching as shown on Sheet 2 of the plan in the “typical joint use easement” detail - all lot lines (including flag lot lines) need to be clearly shown on the face of the plan and the eventual final plat. All easement lines (existing and proposed) must be broken and a lighter weight than the lot lines. (30-1-113) ZR3. Please annotate each easement with the holder of the easement and recording information. (30-1- 113) use. (30-1-113) ZR4. On Sheet 4 Block A -What is the intended use of Lot 67?
