WQ1: Provide a water quality plan using the assumed impervious cover as described in Land Development Code Section 25-8-64. Include all items specified in the Subdivision Application Packet, Page 17. 11 of 13B-7 WQ2: 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 compliance. WQ3: Please provide Certification of Compliance 25-1-83 – Applications Related to a Closed Municipal Solid Waste following website: can http://austintexas.gov/sites/default/files/files/Planning/Applications_Forms/Landfill_Verification_Form.pd f Landfill. The certification found form the be at WQ4: ECM 1.6.5(A) states, “Full sedimentation/filtration or full sedimentation/biofiltration systems shall be required where the City is responsible for maintenance unless topographic constraints make this design unfeasible. Unfeasible is considered: assuming (for the purposes of this selection process only) a maximum ponding depth of three feet in the sedimentation basin, if it is not feasible to obtain an outlet for the drainage from the filtration basin within one hundred (100) feet of the crest of the filtration embankment, then the partial sedimentation/filtration configuration system may be used.” Wetlands Biologist Review - Staryn J Wagner - 512-974-2956 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. CEFs and their setbacks must be shown on all site plan sheets. Site visit completed on 1/19/2021 by Radmon Rice and Staryn Wagner. Several wetlands were identified. The additional wetlands were all found in what appeared to be previously disturbed areas and are presumed to be hydrologically connected to seeps. The dominant hydrophytic vegetation was Eleocharis sp, and Andropogon glomeratus. WB 1. Update 0. Clearly show the boundary of all wetland CEFs and clearly label the features: “WETLAND CEF” on all applicable plan sheets ECM 1.10.4. (This is not necessary for wetlands that will be destroyed and mitigated for.) Site Plan Plumbing - Cory Harmon - 512-974-2882 Pursuant to compliance with Sections 307.1, 609.6, and 721.1 of the 2015 Uniform Plumbing Code, add a plat note that conveys the following: Each Lot within this subdivision shall have separate sewer taps, separate water meters, and their respective private water and sewer service lines shall be positioned or located in a manner that will not cross lot lines. Engineering & Constructability - Jennifer Back, P.E. - jennifer.back@austintexas.gov 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. Transportation Engineering Group will be renamed to Land Review Engineering and Constructability Review Group. The City of Austin – Development Services (DSD) is not able to revise our review 12 of 13B-7 group title until the new version of our database software - AMANDA is fully rolled out. DSD has deemed it to be beneficial to implement a “Constructability” review for all projects submitted, whether located in the City of Austin or the ETJ. The Public Works Department along with other CoA utilities have been experiencing a large amount of construction re-work due to actual field conditions differing from the design construction drawings. Since the constructability review will be looking at multiple disciplines, there is a potential that our review comments may or may not be commented on by other review groups. Our constructability review is conducted to help resolve potential construction issues during the design phase of the project. This review is being done to benefit all involved in the construction project – Developer, Engineer of Record, Contractor and the City of Austin by having another set of eyes reviewing for common constructability issues. Constructability review can lead to enhanced quality, a reduction in change orders and information requests, cost savings, and optimized schedules which reduce the overall time of construction. EC 1. Transportation Criteria Manual Section 5.3.1(a) requires at least 10’ between a curb inlet opening and the edge of a driveway curb return. Provide a driveway layout for all lots that have a nearby curb inlet. I could not locate a storm sewer layout for the approved preliminary plan. For any lots that cannot meet the minimum distance, please email this reviewer to discuss a waiver. END OF COMMENT REPORT 13 of 13B-7
