City Council Meeting <br />May 21, 2024 Page 5 <br /> <br />Engineering Standard Flexibility <br />The Applicant has submitted a memo, appended to this report, which identifies several <br />alternative design considerations necessitating flexibility from the City’s Engineering Design and <br />Construction Standards Manual. The Applicant has made the following requests: <br />1. Commercial lot side yard easement width – easement with reduction from 10’ to 5’ in <br />side yards to increase flexibility of site design. <br />2. Easement grading – increased slope in some easement areas, particularly near infiltration <br />basin potentially requiring revision of stormwater ponding outlot area. <br />3. Stillwater way trail stormwater conveyance – an alternative to a storm sewer system is <br />proposed by altering trail elevation relative to Stillwater Way, and passing stormwater <br />along a drainage ditch and under the required trail using stormwater drainage grates. <br />4. Driveway access and spacing – a minimum of 100’ separation between driveways is <br />proposed. <br />5. Internal turn lane taper and queuing lengths – retain proposed turn lanes as proposed <br />instead of lengthening and relocating property access points. <br />6. Wet pond safety and maintenance benches – a 4’ tall ornamental fence is proposed to <br />keep individuals from falling down wet pond embankments which have a slope over 3:1. <br /> <br />These requests should be reviewed by the City Engineer prior to an approval of the final <br />construction plans. If the final plat is approved, Staff suggest a condition that will require <br />conformance with the City’s adopted Engineering Design Standards Manual dated January 2022 <br />unless otherwise approved by the City. <br /> <br />Review Comments: <br />City Engineer Comments: <br />See attached memo dated April 15, 2024. The City Engineer has suggested that approval, if <br />granted, should be conditional upon addressing each review comment in the Engineer’s review <br />memo. Modifications to the plans are required in the City Engineer’s Memo. Additional information <br />is also required from the Applicant, and any public improvements shall be consistent with the City <br />Engineering Design Standards Manual dated January 2022. <br /> <br />Fire Chief Comments: <br />See attached memo dated March 27, 2024. Conditional approval is suggested. <br /> <br />Landscape Architect Comments: <br />See attached memo dated April 11, 2024. Conditional approval is suggested. <br /> <br />Valley Branch Watershed District: <br />The applicant has submitted a permit application to the Valley Branch Watershed District. Staff <br />are in communication with the VBWD and seeking to coordinate on permitting reviews and <br />timelines as necessary. <br /> <br />City Attorney Review: <br />The City Attorney has reviewed a title commitment and the final plat to produce a plat opinion. <br />The Applicant is currently in the process of addressing all comments of the plat opinion, and will <br />need to do so prior to recording of the final plat. A condition has been added.
