The proposed subdivision is currently served with City of Austin water and wastewater utilities. 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 any future water and wastewater utility improvements, offsite main extensions, system upgrades, utility relocations and or abandonments to serve each lot. WW2. Obtain copies of your current tap records from the AW TAPs office at 512-972-0000 and contact Brad Ward at 512-972-0339 to determine if any non-compliant tap or private plumbing violations will be created by the proposed subdivision and obtain his approval. Written approval from Mr. Ward will be required for successful plat release. 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 - Christine Perez - 512-974-3568 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. WQ 1. Please demonstrate compliance with Environmental Criteria Manual (ECM) 1.6.8 and Land Development Code (LDC) LDC 25-7-61(B)(3) regarding the on- site control of the 2-yr storm for erosion control purposes. ECM 1.6.8 states, “On-site control of the two-year storm is achieved when the developed- conditions peak runoff rate leaving the site for a given drainage area is less than or equal to the existing-conditions runoff rate. The flow rates can be considered equal if the developed rate is no more than one-half (0.5) cfs greater than the existing rate or if the developed rate is no more than one-half (0.5) percent greater than the existing rate and there are no existing erosion problems downstream of the site” (LDC 25-7-61). Please provide data and calculations necessary to verify compliance. WQ 2. Please provide compliance with § 25-1-83 which requires all commercial and multi-family applications for subdivision, site plan, and building permit on tracts greater than one acre or on tracts one acre or less, but within an abandoned landfill buffer as shown on the City of Austin closed landfill map to provide a: 1. City of Austin Certification of Compliance Form; 2. Certificate sealed by a Professional Engineer certifying the site is not over a closed landfill and describing the basis for that determination, or; 3. Development permit from the TCEQ, or; 4. Letter from TCEQ stating that the project is not subject to the requirements of TAC Ch. 330, Subchapter T. The form is on the City of Austin website at http://www.austintexas.gov/sites/default/files/files/Watershed/regulations/Landfill_Verification_ Form.pdf. B-0321 of 23 City Arborist Review - Caitlin Campbell - 512-974-1341 Please be advised that additional comments may be generated as update information is reviewed. If an update has been rejected, reviewers are not able to clear comments based on phone calls, emails, or meetings, but must receive formal updates in order to confirm positive plan set changes. CA 1: Please provide a tree survey for trees 19” and greater in diameter. The tree survey list must include the following: 1) 2) 3) Heritage trees must be indicated with an ‘H’ on the tree survey list; Multi-trunk trees must be indicated with an ‘M’ and each stem must be listed; List the particular species (such as Live Oak, Cedar Elm, Texas Ash, etc) for each tree. Indicating only Oak or only Ash for example, does not comply with ECM requirements. Indicate the date of the survey next to the tree list. The survey must not be older than 5 years. 4) CA 2: CA 3: Please provide a buildability study for the proposed second lot. Based on the maximum impervious cover allowed by code, please include conceptual building footprints, driveway, grading and utility route locations in relation to the protected and Heritage trees on the lot. Please be aware that resubdivisions cannot create a hardship that prevents reasonable use or access to the lot at the time of building permit submittals. The second lot will need to comply with tree preservation regulations at the time of building permit submittal. If there is a possibility that one or several of the trees on the proposed second lot may be considered dead, diseased or an imminent hazard, then I suggest having a third party arborist conduct a condition assessment of those trees to determine if they are worth designing around. Site Plan Plumbing - Brad Ward - 512-972-0339 Rejected Records indicate that there are possibly (2) Water and (2) Wastewater Taps on this property. One of each on the west side and one of each on the east side. Need field verification of which Taps are used by the existing structure, to determine whether a lot line crossing exists with the proposed lot line. Lot line crossing with private plumbing is prohibited by Plumbing Code, and re-subdivision may not cause a code violation. Industrial Waste Review - Rachel Reddig - 512-972-1074 Update #0 July 24, 2019 Approved IW1. The Industrial Waste signature line on the cover sheet is not needed. IW2. Based on the plans submitted, the requirements under Chapter 15-10 of the Austin City Code (Wastewater Regulations) do not apply.

Failure to construct the required sidewalks may result in the withholding of Certificates of Occupancy, building permits, or utility connections by the governing body or utility company." LDC 25-6- 351. • Remove note 17 regarding sidewalk payment. Sidewalk payment can be discussed during the time of residential review. TR3. The resubdivision of the site creates a sight distance issue for the proposed driveway, however it will be allowed due to the site being on a controlled intersection. Add the following note to the plat: • “The driveway for the site shall be located in a position that maximizes the visibility of a vehicle to the adjacent intersection.” End of report B-0323 of 23
