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. DE 1. Fiscal arrangements are required for street, detention, sidewalk, drainage, restoration, erosion controls, water quality ponds. Remember to include fiscal for sidewalks located next to greenbelts, open spaces, landscape areas, drainage easements, etc. [LDC 30-1-132] DE 2. Please explain the origin of plat note 19 regarding drainage easements. The City may request a plat note that states, “All drainage easements are hereby dedicated to the City of Austin.” Generally, Travis County does not want drainage easements dedicated to them. [LDC 30-4-151 and 152] DE 3. Please provide the following plat note, "Prior to construction, except detached single family on any lot in this subdivision, a site development permit must be obtained from the City of Austin." [LDC 30-4-61] DE 4. Please provide the following plat note, “All streets, drainage, sidewalks, erosion controls, and water and wastewater lines are required to be constructed and installed to City of Austin Standards”. [LDC 30-2-38] DE 5. Please provide the following plat note, “No structure shall be occupied until the water quality control and detention facility have been constructed, inspected, and accepted by the City of Austin.” [LDC 30-4-61] DE 6. Please provide the following plat note, “Prior to construction on lots in this subdivision, drainage plans will be submitted to the City of Austin for review. Rainfall run-off shall be held to the amount existing at undeveloped status by ponding or other approved methods.” [LDC 30-4-61] DE 7. It appears that there are concentrated flows and/or floodplain through the property. A drainage easement is required to the limits of the 100 year fully developed flow elevation.

Otherwise, submit the proposed easement with exhibits to this reviewer for processing. [LDC 30-4-151 and 152]. DE 8. Provide the recorded document for the proposed partially released drainage easement. A City of Austin Land Management Easement Release application may be required, if the existing easement is dedicated to the City. [LDC 30-4-151 and 152] 9 of 148 DE 9. Demonstrate the existing detention pond accounts for the proposed subdivision. The proposed subdivision appears to modify the original detention pond design. However, the engineering report only includes the original design. Provide updated analysis and models in the engineering report. Although the engineering report is missing the existing and developed drainage area maps associated with the existing detention pond constructed under C8J-2016-0188.1B, the water quality drainage area map provided (Sheet 13 of 123) indicates that the drainage areas by CBD divert more area to the existing ponds than originally designed. A portion of residential lots and Skytex Street ROW appear to be diverted to the existing pond. [LDC 30-4-61] DE 10. Provide the drainage area map associated with the preliminary plan sheet documenting drainage area calculations by CBD. There are several drainage areas in the calculations that are not clear in the maps. [LDC 30-4-61] DE 11.
